Detailed Implementation

[0017] 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.

[0018] Example

[0019] like Figures 1-4 As shown, this utility model provides a technical solution: a zinc alloy handle anti-bubble die-casting mold, including a base 1 and a drive mechanism 22. A first mold 2 is fixedly connected to the top of the base 1. A groove 3 is opened on one side of the first mold 2. A mold groove 4 is opened on the inner wall of the groove 3. A fixing hole is opened on the top surface of the mold groove 4. A fixing pipe 5 is fixedly connected to the inner wall of the fixing hole. A partition plate 6 is fixedly connected to the inner wall of the fixing pipe 5. An exhaust pipe 7 and a feed pipe 12 are fixedly connected to the top of the fixing pipe 5. A sliding sleeve 9 is slidably sleeved on the outer surface of the exhaust pipe 7. A filter plate 10 is fixedly connected to the inner wall of the sliding sleeve 9. A fixing frame 8 is fixedly connected to one side of the first mold 2. The inner wall of the fixing frame 8 is fixedly connected to the outer surface of the exhaust pipe 7. A plurality of first vent holes 11 are opened on the inner wall of the groove 3.

[0020] In the above embodiments, the fixed pipe 5 and the partition 6 are used for separation, with zinc alloy material flowing on one side of the partition 6 and air flowing on the other side. When the first mold 2 and the second mold 13 come into contact to form a seal, zinc alloy material is injected into the mold groove 4, and the air inside the mold groove 4 will be discharged to the air flow side along with the injection of zinc alloy material, and finally discharged through the exhaust pipe 7, thereby preventing the formation of air bubbles in the zinc alloy material inside the mold groove 4. The sliding sleeve 9 and the filter plate 10 can prevent dust from entering through the exhaust pipe 7, and the sliding sleeve 9 facilitates the replacement of the filter plate 10. At the same time, the bend of the exhaust pipe 7 and the downward radial opening can also prevent dust from entering the interior of the mold groove 4 through the exhaust pipe 7.

[0021] The output end of the drive mechanism 22 is fixedly connected to the second mold 13, and a protrusion 14 is fixedly connected to one side of the second mold 13. The outer surface of the protrusion 14 is slidably connected to the inner wall of the groove 3.

[0022] A template 15 is fixedly connected to one side of the protruding plate 14, and the outer surface of the template 15 is slidably connected to the inner wall of the mold groove 4.

[0023] The second mold 13 has multiple second ventilation holes 16 on one side, and one end of the second ventilation hole 16 is fixedly extended through the outside of the protrusion plate 14.

[0024] Through the above embodiments, the first vent hole 11 and the second vent hole 16 can prevent residual air from being unable to escape when the first mold 2 and the second mold 13 come into contact, thereby increasing the sealing effect between the first mold 2 and the second mold 13. At the same time, the template 15 can seal the mold groove 4, thereby facilitating the entry of zinc alloy material into the mold groove 4 to be die-cast into parts.

[0025] The second mold 13 has multiple grooves 17 on one side. A mold plate 18 is slidably connected between the inner walls of two grooves 17. Two telescopic rods 19 are fixedly connected to one side of the mold plate 18. One end of the telescopic rod 19 is fixedly connected to the inner wall of the groove 17. A spring 20 is provided on the outer surface of the telescopic rod 19. One end of the spring 20 is fixedly connected to one side of the mold plate 18, and the other end of the spring 20 is fixedly connected to the inner wall of one side of the groove 17.

[0026] The inner wall of the groove 3 is provided with a groove 21 that is adapted to the template 18, and the inner wall of the groove 21 is slidably connected to the outer surface of the template 18.

[0027] Through the above embodiments, the die plate 18 can enter through the groove 21, thereby sealing the mold groove 4. Since the die plate 18 is located inside the mold groove 4, after the zinc alloy material is die-cast, the drive mechanism 22 can drive the die plate 18 to pull the zinc alloy handle out of the mold groove 4, thereby facilitating the removal of the zinc alloy handle.

[0028] Working principle:

[0029] like Figures 1-4 As shown, in use, the first mold 2 is fixed by the base 1, and the second mold 13 is driven by the drive mechanism 22. The movement of the second mold 13 will drive the template 15 and the protruding plate 14 into the mold groove 4 and the recess 3 respectively. At this time, due to the air flow generated by the movement, the air in the recess 3 will be discharged through the first vent hole 11 and the second vent hole 16, while the air inside the mold groove 4 will be discharged from the air flow side. At the same time, the mold plate 18 slides into the mold groove 21 and compresses the spring 20. Then the first mold 2 and the second mold 13 contact to form a seal. Zinc alloy material is injected into the mold groove 4. The zinc alloy material enters from the feed pipe 12, and the air inside the mold groove 4 will be discharged to the air flow side with the injection of zinc alloy material, and finally discharged through the exhaust pipe 7, thereby avoiding the formation of air bubbles in the zinc alloy material inside the mold groove 4.

[0030] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
