Description

Technical Field

[0001] This utility model relates to the field of die casting technology, specifically to a die casting equipment for automotive die casting parts. Background Technology

[0002] Die casting is a type of pressure casting part. It is made by using a pressure casting machine equipped with a casting mold. The heated metal such as copper, zinc, aluminum or aluminum alloy is poured into the feed port of the die casting machine and then cast into copper, zinc, aluminum or aluminum alloy parts with the shape and size limited by the mold. Such parts are usually called die castings.

[0003] In the die casting process, liquid material is mostly squeezed laterally into the inner cavity of the mold to form the die. This may result in material accumulating at the outlet of the die casting device and solidifying together with the die casting formed in the inner cavity of the mold. This requires time to process later, which greatly reduces the efficiency of die casting and also makes subsequent demolding work inconvenient.

[0004] Therefore, it is necessary to provide a die-casting equipment for automotive die-casting parts to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a die-casting equipment for automotive die-casting parts to solve the problems existing in the background technology. The technical solution of this utility model addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-casting equipment for automotive die-casting parts, comprising a processing table, a fixed mold fixedly installed at the top center of the processing table, and a die-casting cavity opened at the top of the fixed mold; a horizontally movable moving mold is provided on one side of the top of the processing table, the moving mold cooperating with the fixed mold to form a mold cavity; a fixed base is also fixedly installed on the top of the processing table, a hydraulic rod is vertically arranged on the fixed base, and a die-casting block corresponding to the die-casting cavity is connected to the bottom of the hydraulic rod; an electric push rod for driving the moving mold to move is provided on the side of the moving mold away from the fixed mold, and an ejection mechanism is installed on one side of the fixed mold.

[0007] Preferably, the top center of the fixed seat is provided with a connecting seat, which is fixedly connected to the outer wall of the hydraulic rod, and the bottom of the die-casting cavity is a frustum-shaped structure and is connected to the mold cavity through a transport hole.

[0008] Preferably, the bottom of the die-casting cavity is connected to a bottom groove, a spring is provided in the bottom groove, and a movable block matching the shape of the bottom of the die-casting cavity is connected to the top of the spring.

[0009] Preferably, a support base is fixed on one side of the top of the processing table, and the electric push rod is installed on the top of the support base, with its telescopic end connected to the moving mold.

[0010] Preferably, a limiting groove is provided on the top of the processing table, and a limiting block that slides with the limiting groove is fixed at the bottom of the moving mold.

[0011] Preferably, the ejection mechanism includes fixed long plates symmetrically arranged on both sides of the fixed mold. The fixed long plates have through holes, and connecting long plates pass through the through holes. The two ends of the connecting long plates are limited by fixed blocks, and ejection rods are connected to the side facing the mold cavity.

[0012] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, during the downward movement of the die-casting block, the material and the movable block are first moved downward together. When the movable block moves to the point where the transport hole is exposed, the material is transported into the mold cavity for molding through the transport hole. The movable block is designed to match the bottom shape of the die-casting cavity, so that when the movable block moves to the bottom of the die-casting cavity, the top of the movable block is flush with the bottom of the transport hole. The material can be squeezed into the mold cavity and the transport hole. By introducing an equal amount of material into the die-casting cavity before each molding, excess material can be avoided from condensing with the material inside the mold cavity, reducing the waiting time for subsequent processing and speeding up the overall work efficiency.

[0015] When it is necessary to eject the die-casting part, this utility model only requires pushing the connecting plate towards the fixed mold to move the ejector rod into the mold cavity and eject the die-casting part. When the moving mold moves to the point of splicing with the fixed mold, it will squeeze the ejector rod to be flush with one side of the mold cavity, which will not affect the normal die-casting operation. It is simple, convenient and low cost. Attached Figure Description

The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-6A die-casting equipment for automotive die-casting parts includes a processing table 1, a fixed mold 2 fixedly installed at the top center of the processing table 1, and a die-casting cavity 9 opened on the top of the fixed mold 2; a horizontally movable moving mold 3 is provided on one side of the top of the processing table 1, and the moving mold 3 cooperates with the fixed mold 2 to form a mold cavity; a fixed base 4 is also fixedly installed on the top of the processing table 1, and a hydraulic rod 5 is vertically installed on the fixed base 4, and a die-casting block 6 corresponding to the die-casting cavity 9 is connected to the bottom of the hydraulic rod 5; an electric push rod 15 for driving the moving mold 3 to move is provided on the side of the moving mold 3 away from the fixed mold 2, and an ejection mechanism 7 is installed on one side of the fixed mold 2.

[0026] like Figure 1-6 As shown, the top center of the fixed base 4 is provided with a connecting base 8, which is fixedly connected to the outer wall of the hydraulic rod 5. The bottom of the die casting cavity 9 is a frustum-shaped structure and is connected to the mold cavity through the transport hole 10. The operator can use existing technology to introduce the material into the die casting cavity 9, and then control the die casting block 6 to move downward toward the inside of the die casting cavity 9 through the hydraulic rod 5 to introduce the material into the mold cavity through the transport hole 10 for molding.

[0027] like Figure 1-6 As shown, the bottom of the die-casting cavity 9 is connected to a bottom groove 11. A spring 12 is installed in the bottom groove 11, and a movable block 13 matching the shape of the bottom of the die-casting cavity 9 is connected to the top of the spring 12. When the material enters the die-casting cavity 9, the elastic force of the spring 12 causes the movable block 13 to block the transport hole 10. The material is on top of the movable block 13. During the downward movement of the die-casting block 6, the material and the movable block 13 will move downward together. When the movable block 13 moves to the point where the transport hole 10 is exposed, the material will be transported into the mold cavity for molding through the transport hole 10. The movable block 13 is matched with the bottom shape of the die-casting cavity 9 so that when the movable block 13 moves to the bottom of the die-casting cavity 9, the top of the movable block 13 is flush with the bottom of the transport hole 10. The material can be squeezed into the mold cavity and the transport hole 10. By introducing an equal amount of material into the die-casting cavity 9 before each molding, excess material can be avoided from condensing with the material inside the mold cavity, reducing the waiting time for subsequent processing and speeding up the overall work efficiency.

[0028] like Figure 1-6 As shown, a support base 14 is fixed on one side of the top of the processing table 1. An electric push rod 15 is installed on the top of the support base 14, and its telescopic end is connected to the moving mold 3. The movement of the moving mold 3 can be controlled by the electric push rod 15.

[0029] like Figure 1-6 As shown, a limiting groove 16 is provided on the top of the processing table 1, and a limiting block 17 is fixed at the bottom of the moving mold 3 to slide in the limiting groove 16. The limiting block 17 and the limiting groove 16 enhance the limiting function of the moving mold 3 and prevent the moving mold 3 from deviating during the movement.

[0030] like Figure 1-6 As shown, the ejection mechanism 7 includes fixed long plates 701 symmetrically arranged on both sides of the fixed mold 2. The fixed long plates 701 have through holes 702, and connecting long plates 703 pass through the through holes 702. The two ends of the connecting long plates 703 are limited by fixed blocks 704, and an ejection rod 705 is connected to the side facing the mold cavity. When it is necessary to eject the die casting, it is only necessary to push the connecting long plates 703 towards the fixed mold 2 to drive the ejection rod 705 to move into the mold cavity and eject the die casting. When the moving mold 3 moves to splice with the fixed mold 2, it will squeeze the ejection rod 705 to be flush with one side of the mold cavity, which will not affect the normal die casting operation.

[0031] Working Principle: During use, the operator can use existing technology to guide the material into the die-casting cavity 9. Then, the hydraulic rod 5 controls the die-casting block 6 to move downwards towards the die-casting cavity 9, guiding the material through the transport hole 10 into the mold cavity for molding. During the downward movement of the die-casting block 6, the material and the movable block 13 will move downwards together. When the movable block 13 moves to the point where the transport hole 10 is exposed, the material will be transported into the mold cavity for molding through the transport hole 10. The movable block 13 is designed to match the bottom shape of the die-casting cavity 9, so that when the movable block 13 moves to the bottom of the die-casting cavity 9, the top of the movable block 13 is flush with the bottom of the transport hole 10, allowing the material to be just squeezed into the mold cavity. Before each molding, an equal amount of material is introduced into the die-casting cavity 9 inside the mold cavity and the transport hole 10, which can prevent excess material from condensing with the material inside the mold cavity, reducing the waiting time for subsequent processing and speeding up the overall work efficiency. The limit block 17 and limit groove 16 set up enhance the limiting function of the movement of the moving mold 3, preventing the moving mold 3 from deviating during the movement. When it is necessary to eject the die-casting part, it is only necessary to push the connecting plate 703 towards the fixed mold 2 to drive the ejector rod 705 to move into the mold cavity to eject the die-casting part. When the moving mold 3 moves to the point of splicing with the fixed mold 2, it will squeeze the ejector rod 705 to be flush with one side of the mold cavity, which will not affect the normal die-casting work.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
