Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, specifically relating to a die casting mold for a shell. Background Technology

[0002] In the die-casting process of housing production, the spraying of release agent is a crucial step. The release agent forms a protective film on the mold surface, reducing the adhesion of molten metal to the mold, thus ensuring smooth demolding of the housing and protecting the mold, extending its service life. However, traditionally, the release agent for die-casting housings is mostly sprayed manually, which has several drawbacks. Firstly, manual spraying is inefficient, requiring operators to frequently spray the mold, increasing labor intensity, and easily leading to uneven spraying, resulting in some areas having too much or too little release agent, affecting the demolding effect and surface quality of the housing. Secondly, during die casting, the mold temperature is high, posing certain safety hazards for manual spraying. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 9 As shown, a die-casting mold for a shell includes a base plate 1. A vertical plate 2 is fixedly connected to the upper surface of the base plate 1, and a horizontal plate 3 is fixedly connected to the upper surface of the vertical plate 2. A column 4 is fixedly connected to the bottom of the horizontal plate 3 and the upper surface of the base plate 1. A hydraulic push rod 5 is fixedly connected to the bottom of the horizontal plate 3, and an upper mold 6 is fixedly connected to the bottom of the hydraulic push rod 5. A lower mold 7 is fixedly connected to the upper surface of the base plate 1. A rectangular hole 8 is opened inside the vertical plate 2. Guide posts 9 are fixedly connected to the left and right sides of the inner wall of the rectangular hole 8. A hollow cylinder 10 is sleeved on the surface of the guide post 9. The front and rear sides of the hollow cylinder 10... Each side has a circular hole 11. A spray pipe 12 is fixedly connected to the inner wall of the circular hole 11. An infusion pump 13 is fixedly connected to the upper surface of the base plate 1. An outlet hose 14 is fixedly connected to the outlet end of the infusion pump 13. The surface of the outlet hose 14 is fixedly connected to the inner wall of the spray pipe 12. An inlet hose 15 is fixedly connected to the inlet end of the infusion pump 13. A servo motor 16 is fixedly connected to the upper surface of the base plate 1. A rotating shaft 17 is fixedly connected to the output end of the servo motor 16. A strip ring 18 is fixedly connected to the surface of the rotating shaft 17. The surface of the strip ring 18 is in contact with the surface of the spray pipe 12.

[0030] The rectangular hole 8 has a length greater than the hollow cylinder 10, the height of the rectangular hole 8 is equal to the height of the hollow cylinder 10, and there are two guide posts 9, which are located on the upper and lower sides of the spray pipe 12 respectively.

[0031] The spray pipe 12 includes a round pipe 121, a sealing block 122, a dispensing pipe 123, and a nozzle 124. The surface of the round pipe 121 is fixedly connected to the inner wall of the round hole 11, and the inner wall of the round pipe 121 is fixedly connected to the surface of the liquid outlet hose 14. Both the upper and lower sides of the round pipe 121 are fixedly connected to one end of the dispensing pipe 123, and the other end of the dispensing pipe 123 is fixedly connected to the liquid inlet end of the nozzle 124. The back side of the sealing block 122 is fixedly connected to the front side of the round pipe 121.

[0032] It should be noted that the upper mold 6 can be moved up or down by the hydraulic push rod 5, and the hollow cylinder 10 can only move left or right within the rectangular hole 8 by the guide column 9. The infusion pump 13 is a diaphragm pump or a plunger pump. When the infusion pump 13 is turned on, the release agent can enter the circular tube 121 through the outlet hose 14. Then, the release agent is sprayed out evenly in a mist form through the nozzle 124. At the same time, the servo motor 16 rotates at a speed of 10-20 r / min. The servo motor 16 drives the strip ring 18 to perform eccentric circular motion. Then, the strip ring 18... The spray pipe 12 is driven to swing back and forth, with each swing lasting 3-5 seconds, ensuring that the release agent forms a protective film of uniform thickness (0.1-0.3mm) on the mold surface. When the strip ring 18 rotates from left to right, the spray pipe 12 is moved from the left side of the lower mold 7 to the right side of the lower mold 7 through the strip ring 18. When the strip ring 18 rotates from right to left, the spray pipe 12 is moved from the right side of the lower mold 7 to the left side of the lower mold 7 through the strip ring 18. At this time, the release agent can be evenly sprayed onto the bottom surface of the upper mold 6 and the top surface of the lower mold 7 through the left and right swinging spray pipe 12.

[0033] like Figures 1 to 11 As shown, a circular box 19 is fixedly connected to the upper surface of the base plate 1. A cover 20 is fitted onto the surface of the liquid inlet hose 15. The surface of the circular box 19 is threadedly connected to the inner wall of the cover 20. A retaining ring 21 is bonded to the surface of the liquid inlet hose 15. The upper surface of the retaining ring 21 is in contact with the inner wall of the cover 20. A positioning ring 22 is fixedly connected to the inner wall of the circular box 19. A filter cylinder 23 is fitted into the inner wall of the positioning ring 22. The upper and lower sides of the filter cylinder 23 are in contact with the inner wall of the circular box 19 and the bottom of the retaining ring 21, respectively. The inner wall of the filter cylinder 23 is in contact with the surface of the liquid inlet hose 15. A connecting pipe 24 is fixedly connected to the back of the circular box 19.

[0034] The axis of the circular box 19 coincides with the axis of the positioning ring 22.

[0035] It should be noted that the positioning ring 22 can be used to position the filter cylinder 23 placed inside the circular box 19. The filter cylinder 23 is made of a stainless steel filter screen with a filter aperture of 0.25mm. After the box cover 20 is screwed onto the circular box 19, the filter cylinder 23 can be fixed inside the circular box 19 through the cooperation of the circular box 19, the box cover 20 and the retaining ring 21, and the liquid inlet hose 15 is connected to the circular box 19. At the same time, the filter cylinder 23 inside the circular box 19 will filter the mold release agent entering the liquid inlet hose 15, so that impurities will not enter the infusion pump 13 and the nozzle 124 along with the mold release agent. This reduces the risk of wear and blockage of the precision components inside the infusion pump 13 and the nozzle 124 by impurities, and greatly improves the service life of the infusion pump 13 and the nozzle 124.

[0036] The working principle of this utility model is as follows: Before spraying the release agent, the connecting pipe 24 is connected to the infusion pipe on the release agent storage tank, and the connecting pipe 24, the circular box 19 and the infusion hose 15 are filled with release agent. When spraying the release agent, the distance between the upper mold 6 and the lower mold 7 is adjusted to a suitable size by the hydraulic push rod 5. Then, by starting the servo motor 16, the servo motor 16 drives the strip ring 18 to rotate from left to right. At this time, through the cooperation of the strip ring 18, the circular pipe 121, the vertical plate 2, the rectangular hole 8, the guide column 9 and the hollow cylinder 10, the circular pipe 121 moves from left to right. During the movement of the circular pipe 121 from left to right, the infusion pump 13 is turned on, and the release agent is sprayed out evenly in a mist form through the nozzle 124 by the infusion pump 13. By moving the circular pipe 121, the release agent can be evenly sprayed on the bottom surface of the upper mold 6 and the top surface of the lower mold 7.

[0037] When the circular tube 121 moves to the far right, the servo motor 16 drives the strip ring 18 to move from right to left, and the circular tube 121 moves from right to left. At this time, the release agent can be sprayed evenly on the bottom surface of the upper mold 6 and the top surface of the lower mold 7 again. When the circular tube 121 returns to the far left, the infusion pump 13 is turned off, so that no more release agent is sprayed from the nozzle 124. At the same time, the servo motor 16 stops driving the strip ring 18 to rotate. At this time, the circular tube 121 can be stopped at the far left.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
