Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, specifically a fast self-release die casting mold. Background Technology

[0002] Die casting molds are specialized tools used to rapidly inject molten metal into a mold cavity under high pressure, which then cools and solidifies to obtain metal castings with the desired shape, size, and properties. They are the core components of die casting production, determining the shape, precision, quality, and production efficiency of the die castings. However, the demolding mechanism of traditional molds often requires a lot of manual assistance, and the demolding process is not smooth enough, which can easily lead to damage to the die castings during demolding and reduce the product qualification rate. Utility Model Content

[0003] The purpose of this invention is to provide a fast self-release die-casting mold to solve the problem mentioned in the background art that the demolding mechanism of traditional molds often requires a lot of manual auxiliary operations, the demolding process is not smooth enough, and the die-casting parts are easily damaged during demolding, which reduces the product qualification rate.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a rapid self-release die-casting mold, comprising: a moving mold 1; a fixed mold 2 placed on one side of the moving mold 1; a first forming slide core 5 slidably disposed inside the moving mold 1; a second forming slide core 6 slidably disposed inside the moving mold 1, the second forming slide core 6 cooperating with the first forming slide core 5, and inclined sleeves 4 symmetrically fixed inside both the first forming slide core 5 and the second forming slide core 6; inclined fixing rods symmetrically fixed inside the fixed mold 2, the inclined fixing rods 3 cooperating with the inclined sleeves 4; ejector pins 9 symmetrically slidably disposed inside the moving mold 1; an inner sliding plate 8 slidably disposed inside the moving mold 1, one end of the ejector pin 9 being fixedly connected to the inner sliding plate 8; and a driving part placed on one side of the moving mold 1, the driving part being connected to the inner sliding plate 8.

[0027] It should be noted that in this embodiment, the output end of the external hydraulic cylinder is fixed to the side fixing seat 10. The output end of the hydraulic cylinder drives the side fixing seat 10 and the moving mold 1 to move as a whole to complete the mold opening and closing process. The moving mold 1 closes on one side of the fixed mold 2. The guide rod 18 on one side of the fixed mold 2 is guided and engaged with the guide sleeve 19. When the mold is closed, the inclined fixing rod 3 enters the inclined sleeve 4 opened in the first forming slide core 5 and the second forming slide core 6. The inclined fixing rod 3 moves and adjusts the first forming slide core 5 and the second forming slide core 6 through the inclined sleeve 4. The first forming slide core 5 and the second forming slide core 6 slide within the moving mold 1 and are limited to slide. The first forming slide core 5 and the second forming slide core 6 are moved to the middle position. The first forming slide core 5 and the second forming slide core 6 are engaged with the forming protrusion of the moving mold 1 and combined with the fixed mold 2 to perform die casting. The molten metal is guided from the press through the gating 7. The molten metal enters the mold and fills the cavities of the moving mold 1, fixed mold 2, first forming slide core 5, and second forming slide core 6. After the molten metal is formed, when it is necessary to demold the metal pot, the output end of the external hydraulic cylinder drives the side fixing seat 10 and the moving mold 1 away from the fixed mold 2. The moving mold 1 drives the first forming slide core 5 and the second forming slide core 6 to move as a whole. The inclined sleeve 4 and the inclined fixing rod 3 guide and slide. When the moving mold 1 moves, the first forming slide core 5 and the second forming slide core 6 move outward, and the outward movement completes the demolding. The output end of the cylinder 16 drives the side fixing plate 11 to move. When the side fixing plate 11 moves, it drives the inner sliding plate 8 to slide inside the moving mold 1. The inner sliding plate 8 slides to the outside of the second limiting rod 13. The inner sliding plate 8 presses the spring 14. The inner sliding plate 8 drives each ejector pin 9 to move. The ejector pins 9 eject the formed metal pot on the moving mold 1, and the demolding work is completed.

[0028] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the drive unit includes a side mounting base 15, which is symmetrically mounted on one side of the moving mold 1 by bolts. A cylinder 16 is mounted on one side of the side mounting base 15. A side fixing plate 11 is fixedly connected to the output end of the cylinder 16. The inner side of the side fixing plate 11 is fixedly connected to the inner sliding plate 8. A plurality of third limit rods 17 are symmetrically fixed to one side of the side fixing plate 11. The third limit rods 17 are slidably connected to the side mounting base 15.

[0029] It should be noted that in this embodiment, the output end of the cylinder 16 drives the side fixing plate 11 to move. When the side fixing plate 11 moves, it drives the inner sliding plate 8 to slide and adjust within the moving mold 1. The inner sliding plate 8 drives each ejector pin 9 to move and adjust, thereby completing the ejection of the formed metal pot part from the moving mold 1.

[0030] In one embodiment, such as Figure 1 and Figure 5As shown, multiple second-position limit rods 13 are slidably arranged inside the inner sliding plate 8. The second-position limit rods 13 are fixedly connected to the moving mold 1, and springs 14 are sleeved on the outer side of the second-position limit rods 13.

[0031] It should be noted that in this embodiment, the second limiting rod 13 limits the sliding inside the inner sliding plate 8, thereby restricting the sliding position of the inner sliding plate 8 within the moving mold 1 and improving stability.

[0032] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a first limiting rod 12 is symmetrically slidably arranged inside the side fixing plate 11, and the first limiting rod 12 is fixedly connected to the moving mold 1.

[0033] It should be noted that in this embodiment, the side fixing plate 11 slides on the outside of each first limiting rod 12, thereby improving the adjustment stability of the side fixing plate 11.

[0034] In one embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, a side fixing seat 10 is fixedly connected to one side of the moving mold 1, and multiple limiting side blocks 20 are symmetrically fixed to one side of the fixed mold 2.

[0035] It should be noted that in this embodiment, the output end of an external hydraulic cylinder is installed and fixed to the side fixed seat 10, and the output end of the hydraulic cylinder drives the side fixed seat 10 and the moving mold 1 to move and adjust as a whole.

[0036] In one embodiment, such as Figures 1 to 4 As shown, a plurality of guide rods 18 are symmetrically fixed to one side of the fixed mold 2, and a plurality of guide sleeves 19 that cooperate with the guide rods 18 are symmetrically fixed to the inside of the moving mold 1. A sprue 7 is provided inside the fixed mold 2.

[0037] It should be noted that in this embodiment, the guide rod 18 cooperates with the guide sleeve 19 to guide the mold closing process between the moving mold 1 and the fixed mold 2.
