Aluminum alloy die-casting mold

Abstract

This utility model discloses an aluminum alloy die-casting mold, belonging to the field of aluminum alloy die-casting technology. The mold stabilizing assembly has two symmetrical sets, and the aluminum alloy automatic mold opening assembly is located between the two sets of mold stabilizing assemblies. In this manner, the first cylinder is activated to drive the transmission rod to move. When the transmission rod moves, it pushes the transmission plate to move in the same direction. The second positioning rod and the first positioning rod on the transmission plate are slidably disposed in the second positioning groove and the first positioning groove, respectively. The first positioning groove and the second positioning groove are '7' shaped, so the transmission plate gradually moves upward. Simultaneously, the upward movement of the transmission plate drives the clamping plate to move upward. When the second positioning rod and the first positioning rod move to the horizontal groove at the upper end of the second positioning groove and the fixing rod, the transmission plate and the clamping plate do not move upward but only move horizontally. The horizontally moving clamping plate interlocks the clamping groove and the recess. Under the clamping of multiple sets of clamping plates, the upper mold and the lower mold are clamped and fixed.

Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy die casting technology, specifically to an aluminum alloy die casting molding mold. Background Technology

[0002] Aluminum alloy is an alloy material formed by adding a certain amount of other alloying elements to aluminum as the base material.

[0003] In existing technologies, aluminum alloys are lightweight, high-strength, corrosion-resistant, and easy to process and form. They are key structural materials for achieving weight reduction, energy saving, and durability in fields such as aviation, transportation, construction, and electronics. Aluminum alloys are often produced by die casting molds. Aluminum alloy raw materials are poured into the lower mold, and then the upper mold is placed on top of the lower mold and the two are pressed against each other. The upper and lower molds are fixed by multiple sets of bolts, thereby producing aluminum alloys.

[0004] However, in the production of aluminum alloys, traditional die-casting molds use multiple sets of bolts to fix the upper and lower molds to their surfaces. Disassembling and assembling the molds requires tools, which is very time-consuming and labor-intensive and not convenient.

[0005] Based on this, the present invention designs an aluminum alloy die-casting mold to solve the above problems. Utility Model Content

[0008] An aluminum alloy die-casting mold includes an upper mold and a lower mold, and also includes a mold stabilizing component and an aluminum alloy automatic mold opening component;

[0009] The upper mold is slidably disposed on the upper surface of the lower mold;

[0010] The lower mold is equipped with a mold stabilizing component that can stabilize the connection between the upper mold and the lower mold.

[0011] The lower mold is equipped with an automatic mold opening component for aluminum alloys.

[0012] The mold stabilizing assembly is provided in two symmetrical sets, and the aluminum alloy automatic mold opening assembly is located between the two sets of mold stabilizing assemblies;

[0013] The mold stabilizing component includes a driving component and a clamping component, which are connected. The clamping component has two symmetrical sets, and the driving component is located between the two sets of clamping components.

[0014] Furthermore, a forming chamber is provided on the upper surface of the lower mold, and a storage chamber and a placement chamber are provided inside the lower mold. A through hole is provided on the bottom surface of the inner wall of the forming chamber. Multiple sets of through holes are symmetrically distributed, and the through holes connect the forming chamber and the storage chamber, and the storage chamber and the placement chamber are connected.

[0015] Furthermore, the inner wall side surface of the lower mold is provided with a first positioning groove and a second positioning groove, and multiple sets of the first positioning groove and the second positioning groove are symmetrically distributed. Multiple sets of through grooves are provided on the two end surfaces of the lower mold, and the through grooves extend into the interior of the lower mold.

[0016] Furthermore, the drive assembly includes a fixed rod, a second positioning rod, a transmission plate, a first positioning rod, an annular block, a transmission rod, a first cylinder, and a lifting ring. The fixed rod is fixedly disposed on the inner wall side surface of the lower mold. The first cylinder is rotatably disposed inside the lower mold. The lifting ring is fixedly disposed at the end of the first cylinder. The middle outer surface of the transmission rod is fixedly connected to the output end of the first cylinder. The transmission plate is slidably disposed inside the lower mold. The transmission plate has two symmetrical sets. The second positioning rod and the first positioning rod are both fixed on the side surface of the transmission plate. The annular block is fixedly disposed on the lower inner wall of the transmission plate.

[0017] Furthermore, the outer surface of the fixing rod is rotatably connected to the inner wall of the lifting ring, the first positioning rod and the second positioning rod are slidably connected to the first positioning groove and the second positioning groove respectively, and the transmission rod has annular grooves on its outer surfaces at both ends, and the annular block is rotatably connected to the annular groove.

[0018] Furthermore, the clamping assembly includes a clamping plate and a fixing block. The fixing block is fixedly disposed on both end surfaces of the upper mold, and the fixing block is provided in two sets symmetrically distributed. The clamping plate is fixedly disposed on the upper surface of the end of the transmission plate, and the clamping plate is located outside the lower mold.

[0019] Furthermore, the end of the transmission plate is slidably connected to the through groove, the outer surface of the fixing block is provided with a groove, and the side surface of the end of the clamping plate is provided with a clamping groove, which is slidably connected to the groove.

[0020] Furthermore, the automatic mold opening assembly for aluminum alloy includes a push plate, ejector pins, and a second cylinder. The second cylinder is fixedly installed inside the placement chamber. The lower center of the push plate is fixedly connected to the output end of the second cylinder.

After the aluminum alloy is formed in the mold, the upper mold is removed from the lower mold. Then, the second cylinder is started to drive the push plate to move upward. The upward movement of the push plate will drive the ejector pin to move upward. Multiple sets of ejector pins will lift the formed aluminum alloy from the inside of the forming chamber, making it convenient to remove the aluminum alloy.

When the aluminum alloy raw material is placed in the forming chamber and the upper mold is placed on top of the lower mold, the first cylinder is activated to drive the transmission rod to move. Since the transmission rod is rotatably connected to the transmission plate, the transmission rod will push the transmission plate to move in the same direction when it moves. The second positioning rod and the first positioning rod on the transmission plate are slidably set in the second positioning groove and the first positioning groove, respectively. The first positioning groove and the second positioning groove are in the shape of '7', so the transmission plate will gradually move upward. When the transmission plate moves upward, it will drive the clamping plate to move upward. When the second positioning rod and the first positioning rod move to the horizontal groove at the top of the second positioning groove and the fixed rod, the transmission plate and the clamping plate will not move upward but will only move horizontally. The horizontally moving clamping plate will lock the clamping groove and the recess into each other. Under the clamping of multiple sets of clamping plates, the upper mold and the lower mold are clamped and fixed. Attached Figure Description
