Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and in particular to a mold for easy demolding of internal plastic parts for audio equipment. Background Technology

[0002] With the significant improvement in people's quality of life, the market demand for consumer electronics products has shown explosive growth, and audio equipment, as a popular category, is no exception. The battery box inside the audio equipment serves as the carrier of the internal lithium battery and requires the use of molds in the production process. Molds are tools used in industrial production to shape items. They use specific shapes and structures to shape raw materials into the required product shape under certain process conditions.

[0003] Currently, after production is completed using traditional molds, plastic parts are prone to getting stuck in the lower mold, making them difficult to demold. In this case, manual demolding is required, which may require the use of tools to pry and pull, which is not only time-consuming and labor-intensive, but also affects the subsequent production of plastic parts.

[0004] In response to the technical problem of the lack of a demolding structure after the plastic parts inside the mold are produced, this application proposes a mold for plastic parts inside an audio system that facilitates demolding. Utility Model Content

[0005] The purpose of this invention is to address the lack of a demolding structure for plastic parts after production. This invention provides a convenient demolding mold for internal plastic parts in audio equipment. A push plate ejects the plastic parts from the lower mold, facilitating demolding, reducing the difficulty of manual operation, improving production efficiency, and allowing the disc-shaped condenser to cool the plastic parts in the lower mold, thus shortening the molding cycle and further increasing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold for easily demolded internal plastic parts of an audio device, comprising a base, with support columns fixedly connected to the four corners of the top of the base, a top plate fixedly connected to the top of the support columns, a hydraulic cylinder fixedly connected to the top of the top plate, a lower pressure plate fixedly connected to the driving end of the hydraulic cylinder, connecting rods fixedly connected to both sides of the bottom end of the lower pressure plate, a rotating shaft rotatably connected to the inner wall of the connecting rods, a control plate fixedly connected to the outer wall of the rotating shaft, a lower mold fixedly connected to the top of the base, push plates slidably connected to both sides of the inner wall of the bottom end of the lower mold, a discharge assembly provided at the bottom end of each push plate, a water tank provided at the front end of the base, a pump body fixedly connected to the right end of the water tank, and a cooling assembly provided at the right end of the pump body.

[0007] Furthermore, the discharge assembly includes movable plates that are all disposed at the bottom end of the push plate. The outer wall of the movable plate is slidably connected to the inner wall of the base, and the opposite ends of the movable plates on the left and right sides are both located below the control plate.

[0008] Furthermore, two reset springs are fixedly connected to opposite ends of the movable plates on both the left and right sides, and the opposite ends of the reset springs are fixedly connected to the inner wall of the base.

[0009] Furthermore, the cooling assembly includes a water inlet pipe fixedly connected to the right end of the pump body, a disc-shaped condenser pipe fixedly connected to the other end of the water inlet pipe, the disc-shaped condenser pipe being located below the lower mold, a water outlet pipe fixedly connected to the other end of the disc-shaped condenser pipe, and the other end of the water outlet pipe fixedly connected to the top of the water tank.

[0010] Furthermore, an upper mold is fixedly connected to the bottom end of the lower pressure plate, and the upper mold is located above the lower mold.

[0011] Furthermore, a spring coil is fixedly connected to the outer wall of the rotating shaft, and the other end of the spring coil is fixedly connected to the inner wall of the connecting rod.

[0012] Furthermore, each of the connecting rods on the left and right sides is fixedly connected to a limiting plate at one end, and the top of the limiting plate is close to the bottom of the control plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the upper and lower molds are closed, the connecting rod drives the control plate to move below the moving plate. When the upper mold rises, the control plate will move the moving plate to the right, so that the push plate pushes out the plastic battery box in the lower mold, which facilitates demolding, reduces the difficulty of manual operation, and improves production efficiency.

[0015] 2. In this utility model, water in the water tank is pumped to the disc-shaped condenser tube by the pump body, so that the disc-shaped condenser tube cools the plastic parts in the lower mold, which shortens the molding cycle of the plastic parts and improves production efficiency.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a mold for easily demolded internal plastic parts of an audio device, comprising a base 1, with support columns 2 fixedly connected to the four corners of the top of the base 1, a top plate 3 fixedly connected to the top of the support columns 2, a hydraulic cylinder 4 fixedly connected to the top of the top plate 3, a lower pressure plate 20 fixedly connected to the drive end of the hydraulic cylinder 4, connecting rods 6 fixedly connected to both sides of the bottom end of the lower pressure plate 20, a rotating shaft 7 rotatably connected to the inner wall of the connecting rods 6, a control plate 8 fixedly connected to the outer wall of the rotating shaft 7, a lower mold 11 fixedly connected to the top of the base 1, and push plates 12 slidably connected to both sides of the inner wall of the bottom end of the lower mold 11. (See reference...) Figure 4 Each push plate 12 has a movable plate 13 at its bottom end. The outer wall of the movable plate 13 is slidably connected to the inner wall of the base 1. The opposite ends of the movable plates 13 on both sides are located below the control plate 8. Two reset springs 14 are fixedly connected to the opposite ends of the movable plates 13 on both sides. The opposite ends of the reset springs 14 are fixedly connected to the inner wall of the base 1. The bottom end of the lower pressure plate 20 is fixedly connected to the upper mold 5, which is located above the lower mold 11. The outer wall of the rotating shaft 7 is fixedly connected to the spring coil 9, and the other end of the spring coil 9 is fixedly connected to the inner wall of the connecting rod 6. The opposite ends of the connecting rods 6 on both sides are fixedly connected to the limit plate 10, and the top of the limit plate 10 is close to the bottom end of the control plate 8.

[0025] Specifically, when the connecting rod 6 drives the control plate 8 to move downward and contact the moving plate 13, the moving plate 13 cannot move up or down, so the moving plate 13 will squeeze the control plate 8, causing the control plate 8 to rotate into the connecting rod 6. When the connecting rod 6 drives the control plate 8 to move upward, the limiting plate 10 at the bottom of the control plate 8 restricts the control plate 8 from flipping downward, causing the control plate 8 to squeeze the moving plate 13 to move towards the middle, while stretching the return spring 14. After the moving plate 13 pushes the plastic part out through the push plate 12, the return spring 14 pulls the moving plate 13 back to its original position, and the push plate 12 also returns to its position under gravity. A heating wire is installed in the upper mold 5. The heating wire converts electrical energy into heat energy to heat and melt the plastic raw material, so that it forms the shape of a battery box in the mold and waits for cooling.

[0026] Reference Figure 5 A water tank 15 is provided at the front end of the base 1. A pump body 16 is fixedly connected to the right end of the water tank 15. A water inlet pipe 17 is fixedly connected to the right end of the pump body 16. A disc-shaped condenser pipe 18 is fixedly connected to the other end of the water inlet pipe 17. The disc-shaped condenser pipe 18 is located below the lower mold 11. A water outlet pipe 19 is fixedly connected to the other end of the disc-shaped condenser pipe 18. The other end of the water outlet pipe 19 is fixedly connected to the top of the water tank 15.

[0027] Specifically, the disc-shaped condenser tube 18 is made of copper alloy. Copper has excellent thermal conductivity and can quickly and effectively transfer heat, allowing the water in the disc-shaped condenser tube 18 to absorb the heat in the lower mold 11, thereby accelerating the cooling of the plastic parts in the lower mold 11 and enabling them to be molded quickly. A water inlet is fixed above the water tank 15, which can add water to the water tank 15.

[0028] Working principle: During use, the plastic raw material is placed into the lower mold 11. Then, the hydraulic cylinder 4 is activated, causing the lower pressure plate 20 to move downwards. The lower pressure plate 20 then drives the connecting rods 6 on both sides to insert into the inner wall of the base 1. The connecting rods 6 cause the control plate 8 to contact the moving plate 13, thus causing the control plate 8 to rotate into the connecting rod 6 and drive the rotating shaft 7 to rotate. The rotating shaft 7 then retracts the spring coil 9. When the connecting rod 6 moves below the moving plate 13, the spring coil 9 will spring back the control plate 8 to its original position. Simultaneously, the lower pressure plate 20 moves downwards, causing the upper mold 5 to close with the lower mold 11. The heating wire in the upper mold 5 is activated to heat and melt the plastic raw material in the lower mold 11. After cooling, the pump body 16 at the right end of the water tank 15 is started. The pump body 16 pumps the water in the water tank 15 to the disc-shaped condenser tube 18 through the water inlet pipe 17. The disc-shaped condenser tube 18 rapidly cools the lower mold 11, accelerating the molding of the plastic part. The water in the disc-shaped condenser tube 18 will return to the water tank 15 through the water outlet pipe 19. After the plastic part is molded, the hydraulic cylinder 4 is started to drive the lower pressure plate 20 to move upward, thereby driving the connecting rod 6 to move upward. The connecting rod 6 then drives the control plate 8 to move upward. When the control plate 8 moves upward, it squeezes the moving plates 13 on both sides towards the middle. The moving plates 13 then squeeze the push plate 12 upward, causing the push plate 12 to demold the plastic part in the lower mold 11.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
