Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy die casting pressing devices, in particular to an aluminum alloy die casting processing regulating pressing device. Background Art

[0002] Aluminum alloy die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour the heated liquid aluminum alloy and other metals into the inlet of the die-casting machine. The die-casting machine is die-cast to cast aluminum alloy parts of the shape and size restricted by the mold. Such parts are usually called die-castings.

[0003] The existing pressing device for aluminum alloy die-castings cannot freely adjust the thickness of the die-castings, and different molds need to be replaced, which is more troublesome, and the supporting force at the adjustment point of the telescopic rod is poor and easy to be damaged; the existing pressing device for aluminum alloy die-castings lacks a limiting structure, which may cause misalignment and affect the quality of the castings, and long-term die-casting will cause wear between the molds and cause irreversible damage. Therefore, the demand for an aluminum alloy die-casting processing and adjustable pressing device is increasing.

[0004] Therefore, in order to solve the above problems, an adjustable pressing device for aluminum alloy die casting processing is proposed in the market. Summary of the invention

[0005] The purpose of the utility model is to provide an adjustable pressing device for processing aluminum alloy die castings to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A processing and adjustable pressing device for aluminum alloy die-castings comprises a lower die and an upper die, wherein a first limiting groove is provided inside the lower die, a hydraulic rod is fixedly connected to the top of the upper die, a punching block is fixedly connected to the bottom center of the upper die, a punching groove is provided at the top center of the lower die, a fixing rod is fixedly connected to the bottom edge of the upper die, a limiting plate is fixedly connected to the outside of the fixing rod, a fixing shell is spirally connected to the outside of the fixing rod, limiting holes are provided on the outsides of the fixing rod and the fixing shell, a fixing pin is spirally connected to the inside of the limiting hole, and an operating table is fixedly connected to the bottom end of the lower die.

[0008] Preferably, a spring is fixedly connected inside the first limiting groove, a buffer plate is fixedly connected to the top of the spring, a first rubber layer is fixedly connected to the top of the buffer plate, a wear-resistant layer located above the first rubber layer is fixedly connected inside the first limiting groove, and a second rubber layer is fixedly connected to the bottom end of the fixed shell.

[0009] Preferably, the spring, the buffer plate and the first rubber layer form a group, there are two groups in total, and they are symmetrically arranged inside the first limiting groove.

[0010] Preferably, the fixing rod, the limiting plate, the fixing shell, the limiting hole, the fixing pin and the second rubber layer form a group, there are two groups in total, and they are symmetrically arranged on the surface of the upper mold.

[0011] Preferably, a punching block is slidably connected inside the punching groove, and the shape of the punching block is completely consistent with the punching groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, by setting the lower mold, the first limiting groove, the upper mold, the stamping block, the stamping groove, the fixed rod and the fixed shell and other components, the fixed rod and the fixed shell are set below the upper mold, and the overall length of the fixed rod and the fixed shell can be freely adjusted by spiral rotation, and then the fixing pin is screwed into the limiting hole for double fixing, which greatly improves the supporting force of the telescopic rod. The fixed rod and the fixed shell are a telescopic rod structure. When the upper mold is pressed down, the fixed rod and the fixed shell will enter the inside of the first limiting groove to support the upper mold, increase the distance between the upper mold and the lower mold, and achieve the effect of adjusting the thickness of the aluminum alloy die-casting, thereby solving the problem that the existing pressing device of the aluminum alloy die-casting cannot freely adjust the thickness of the die-casting, and different molds need to be replaced, which is more troublesome, and the supporting force of the telescopic rod adjustment part is poor and easy to be damaged;

[0014] 2. In the utility model, by setting components such as a fixing rod, a fixing shell, a first limiting groove, a limiting plate, a second rubber layer, a spring, a buffer plate, a wear-resistant layer and a first rubber layer, the length of the fixing rod and the fixing shell is greater than the stamping block, and the fixing shell will enter the first limiting groove one step ahead. The insertion of the fixing rod and the fixing shell into the first limiting groove can play a limiting role to prevent displacement during the die-casting process and affect the quality of the aluminum alloy component. The wear-resistant layer can protect the first limiting groove to prevent wear of the first limiting groove. The spring, the buffer plate, the first rubber layer and the second rubber layer can play an effective shock-absorbing and buffering effect to protect the upper mold and the lower mold and reduce the impact force on the lower mold when the upper mold is pressed down, thereby solving the problem that the existing pressing device of the aluminum alloy die-casting lacks a limiting structure, may cause dislocation, and affects the quality of the casting, and long-term die-casting will cause wear between the molds and cause irreversible damage.
