Description

Technical Field

[0001] The utility model relates to the technical field of zinc alloy die-casting molds, in particular to a zinc alloy die-casting mold with an inclined top molding and a lateral core pulling mechanism. Background Art

[0002] The die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a special die-casting forging machine. The basic process of die-casting is: the molten metal is first cast and filled into the mold cavity at a low or high speed. The mold has a movable cavity surface, which is pressurized and forged as the molten metal cools, which not only eliminates the shrinkage defects of the blank, but also makes the internal structure of the blank reach the broken grains in the forged state.

[0003] The existing Chinese utility model patent with reference announcement number: CN219464724U discloses a zinc alloy die-casting mold with inclined top molding and lateral core pulling mechanism. The utility model includes a lower mold base, and the upper side of the lower mold base is symmetrically fixedly connected with two supporting bottom blocks, and the lower mold base between the two supporting bottom blocks is provided with a buffer stripping plate, and the upper side of the buffer stripping plate is movably connected with a lower fixed mold seat, and the upper side of the lower fixed mold seat is provided with a first mold core installation groove, and the lower mold core is fixedly provided in the first mold core installation groove. The mold of the utility model has high precision, good quality and long service life, and can effectively solve the problem of doubling the number of mold production, thereby improving production capacity and production efficiency. The mold is fully formed, reducing the subsequent drilling process steps, reducing the investment of manpower and material resources, reducing production costs, and ensuring the normal progress of the production plan.

[0004] The side core and the bottom mold of the existing mold with a lateral core pulling mechanism are in contact with each other. During the die-casting process, molten metal may enter the gap between the side core and the bottom mold, making the open hole structure on the side of the casting unable to penetrate. In addition, the existing mold is tightly fitted between the casting and the bottom mold after the die-casting is completed, making it very inconvenient to demold the casting. Utility Model Content

The movable plate and the top column apply a vertical upward force to the casting embedded above the bottom mold, so that the casting falls off the bottom mold. In this way, the demoulding operation can be completed during the resetting of the bottom plate, thereby facilitating the removal of the casting after the die-casting operation is completed.

[0032] The movable end of the pneumatic spring 112 is fixedly connected to the rear side vertical surface of the slider 110. A slope structure matching the oblique wedge structure on the bottom surface of the limit block 15 is arranged at the upper rear portion of the slider 110. A side core structure is arranged at the front end of the slider 110. The side core structure of the slider 110 passes through the end of the slide plate 19 and is inserted into the interior of the bottom mold 114.

[0033] The side of the bottom mold 114 is provided with an open hole structure matching the side core structure of the slider 110, a sliding connection is formed between the movable plate 115 and the bottom mold 114, a connecting rod 116 passes through the bottom plate 113 and the bottom mold 114, and a sliding connection is formed between the connecting rod 116 and the bottom plate 113 and the bottom mold 114, a top column 118 passes through the bottom plate 113 and the bottom mold 114, and the top end of the top column 118 and the top surface of the bottom mold 114 are in the same plane.

[0034] Specifically, the support frame 1 can limit the displacement distance of the cooperative plate 117, the limit rod 11 can limit the movement direction of the bottom plate 113, and limit the displacement distance of the chute plate 19, the top plate 12 can fix the position of the inclined top 13, the pouring port 14 can facilitate the pouring of molten metal, the limit block 15 can limit the position of the slider 110, the connecting plate 16 can fix the position of the top mold 18 with the receiving plate 17, the receiving plate 17 can support the top mold 18, the top mold 18 can facilitate die casting, and the chute plate 19 can limit the movement of the slider 110.

[0035] When in use, it is first necessary to fix the top plate 12 and connect the hydraulic equipment with the front and rear sides of the support frame 1 and the bottom plate 113. During the die-casting process, the bottom plate 113 is driven upward by the hydraulic equipment so that the top surface of the bottom plate 113 contacts the bottom surface of the slide plate 19. Then the hydraulic equipment will drive the bottom plate 113 and the slide plate 19 to move upward. During the upward movement of the slide plate 19, the inclined top 13 is inserted into the interior of the slider 110, so that the slider 110 moves forward and stretches the pneumatic spring 112. When the top surface of the slide plate 19 contacts the receiving plate 17, the side core structure of the slider 110 will pass through the slide plate 19, and the end of the side core structure will be inserted into the opening structure of the bottom mold 114. When die-casting is performed, the side core connects the facades on the left and right sides of the die-casting space, thereby ensuring the opening of the side of the casting after the die-casting operation is completed. The hole structure can be through-connected. After the die-casting is completed, the hydraulic equipment drives the bottom plate 113 to move downward, and the slide plate 19 will move downward with the bottom plate 113 under the action of its own gravity. At this time, the slider 110 is reset by the reaction force of the inclined top 13 and the pneumatic spring 112. When the bottom surface of the cooperative plate 117 contacts the top surface of the support frame 1, the position of the cooperative plate 117 will be limited by the support frame 1, and the hydraulic equipment continues to drive the bottom plate 113 to move downward, so that the relative position between the top column 118, the movable plate 115 and the bottom mold 114 changes, and a vertical upward force is applied to the casting embedded above the bottom mold 114 through the movable plate 115 and the top column 118, so that the casting falls off the bottom mold 114. In this way, the demolding operation can be completed during the resetting process of the bottom plate 113, thereby facilitating the removal of the casting after the die-casting operation is completed.
