Positioning structure of die-casting mold

Abstract

The utility model discloses a positioning structure of a die-casting mold, and the mold comprises a lower die sleeve and a support block, the positioning structure and a connecting structure are arranged between the lower die sleeve and the support block, the positioning structure comprises a cylindrical positioning block and a positioning bolt, the upper part of the positioning block is matched with the lower die sleeve, the middle part and the lower part of the positioning block are matched with the support block, and the positioning bolt is arranged on the support block; and a bolt hole with an opening on the lower end is arranged inside the positioning block, and the upper part of the positioning bolt stretches into the bolt hole to be connected with the positioning block. Due to adopting the positioning structure, the positioning precision of the die sleeve and the support block is high, and the problem of the damage of the mold and a press machine caused by easiness in position deviation of the support block and the die sleeve in the casting process can be effectively overcome.
  • Description

    Positioning structure of the casting mold

    FIELD

    Background technique

    A method of casting is the casting of liquid forging, casting on a dedicated usually completed casting mold.

    Die casting is commonly used by the positioning pin die housing is fixedly connected to the mold foot. However, in the casting production process, since the offset between the position of the die pin and die sets, it can easily lead to damage to the mold and the press. Therefore, how to improve the positioning accuracy between the die and mold sets of feet is an urgent need to address the problem.

    Chinese Patent Publication No. Authorization: CN202088334U, authorized announcement December 28, 2011, discloses a mold fixing structure includes two templates, the template is fixed to a positioning block, said positioning block is provided there are holes provided in the hole in the fixture block, said fixture block with the pore size matches the block is provided with projections on the card, a spring between the clamping block and the template; template another card has a limit plate, the stop plate is provided with the card stopper protrusion corresponding to the block on the card. The invention is a positioning structure for positioning the two templates. Accordingly, the invention deficiency is, single function, can not be used for positioning the mold die housing feet.

    SUMMARY

    The present invention is to overcome the lack of a single casting mold of the prior art functions, can provide a structure for positioning the mold die sets foot and precise positioning of the casting mold.

    To achieve the above object, the present invention adopts the following technical scheme:

     Positioning structure types of die casting mold, said mold comprising a lower mold and a sleeve mold feet, positioning structure and the connecting structure provided between the lower mold and the mold pin sleeve, said positioning structure comprising a cylindrical positioning block and bolts , the upper and the lower mold block positioning sleeve cooperating positioning block, the lower leg cooperating with the die, die bolts provided on the foot; positioning block equipped with an open lower end of the bolt holes, the bolt extends into the upper locating hole and the bolt positioning block is connected.

    The positioning structure of the present invention can accurately position the sleeve and the lower mold die pin connection structure of the mold and the lower mold pin fixedly connected sleeve; and a positioning structure such that the connection structure for the subsequent connecting operation becomes simple and fast.

     by a connecting structure provided between the die and the die sets several feet spaced bolts like configuration. The length of the connecting bolts is 140 to 250 mm.

     The present invention effectively overcomes casting engineering, between the mold and die sets foot easily shift position, the press mold and cause problems of damage.

     During operation the lower mold and the mold sleeve positioning pin connection comprises the steps of:

     First, the positioning structure and the positioning block fixed to the positioning bolts;

     Then, the positioning pieces into the positioning holes of the lower mold set, accurate positioning between the lower position and the mold die set pin;

     Finally, the connection structure is connected to the lower die housing is fixed mold pin.

    Advantageously, an annular chamfered upper edge of the positioning block. The mating annular chamfered positioning operation block mold and the lower mold chase foot easier.  Advantageously, the upper side surface of the positioning block is inclined to the axis of the positioning block, the angle between the side surface and is positioned with an upper surface of the vertical block is O. 5 degrees to 3 degrees. This structure is provided so that the positioning block with the lower mold sleeve easier.

     Advantageously, the diameter of said positioning block is from 40 to 60 mm, the height of the positioning block is 30-50 mm.

     Advantageously, the positioning bolt length is 180-290 mm, the diameter of the bolt is positioned 20 to 36 mm.

     As a preferred fit between the positioning sleeve and the lower mold block gap O. 03 O. 05 mm mm. With a limited size of the gap, improves the positioning accuracy between the positioning sleeve and the lower mold block.

     Preferably, as with the gap between the positioning pin and the die block is O. 03 O. 05 mm mm. With a limited size of the gap, improves the positioning accuracy between the positioning pin and the mold block. Accordingly, the present invention has the following advantages:

     (I) a positioning structure such that the subsequent connection structure connecting operation becomes simple, quick;

     (2) high precision positioning between the mold and the mold pin sleeve, effectively overcome in casting engineering, between the mold and die sets foot easily shift position, the press mold and cause problems of damage.

    BRIEF DESCRIPTION

    FIG. 2 is a schematic cross-sectional view of the portion AA of FIG. I.

    FIG: lower mold chase I, die 2 feet, positioning blocks 3, 4 bolts, connecting bolt 5.

    detailed description

    The following disclosure further description of the accompanying drawings and do specific embodiments.

    Example I is shown in FIG positioning structure of a die casting mold, said mold comprising a lower mold and a sleeve mold foot, I 2, connecting structure and a positioning structure disposed between the mold and the lower mold chase foot, the positioning said positioning structure comprising a cylindrical block 3 and bolts 4, is connected by a screw connection structure 3 are arranged equally spaced between the die and the die housing provided in the foot 5. Length of the connecting bolt 180 is halo meters.

     As shown in FIG. 2, the upper and the lower mold block positioning sleeve cooperating positioning block, the lower leg cooperating with the die, die bolts provided on the foot; positioning block equipped with an open lower end of the bolt holes, positioning an upper bolt extending into the bolt hole and connected to the positioning block.

    An annular chamfered upper edge positioning block. An upper side inclined toward the axis of the positioning block positioning block and an upper side surface of the positioning angle between the vertical plane of the I block.

    Diameter  The positioning block is 50 mm and a height of 40 mm positioning block.

    positioned bolt length of 250 mm and a diameter of 30 mm bolts.

    With the gap between the positioning block and the lower die sets is O. 04 mm. With the gap between the positioning pin and the die block is

    O. 03 Halo meters.

    FIG. I, there are provided two positioning structures and three sets of the connection structure between the lower mold and the mold pin according to the present embodiment.

    The operation sets the lower mold and the mold positioning pin connection comprises the steps of:

    First, the two bolts were placed in the bolt holes in the foot mode, the two positioning blocks are fixedly connected to the upper end of the positioning bolt; [0037] Then, the two blocks are placed in the lower mold positioning sleeve positioning holes, the positioning accuracy and the lower mold die set pin;

    Finally, with three connecting bolts sleeve fixedly connected to the lower mold and the mold pin.The present invention relates to a mold technical field, particularly relates to a mold and the mold sleeve precise positioning pin positioning structure of the die casting mold
