Description

Technical Field

[0001] This utility model relates to the field of camera housing processing, and in particular to a mold for camera housing. Background Technology

[0002] The molds for processing camera housings are usually made using injection molding, a method of industrial product manufacturing that is widely used in the production of camera housings. The molds are usually made of metal and include an upper mold core and a lower mold core. The surface of the upper mold core is recessed inward to form several molding cavities. The bottom and side walls of the molding cavities are respectively provided with arc-shaped molding areas and molding platforms. These designs allow the injection molding material to cover and fill the entire molding area well.

[0003] A search revealed Chinese Patent Publication No. CN221187315U, which discloses a mold for camera housings. By incorporating a fixed plate, support rod, connecting plate, sliding sleeve, sliding rod, buffer spring A, buffer spring B, and rubber pad, it solves the problem that existing molds for camera housings cannot reduce the impact force on the mold during stamping, thus affecting the mold's service life.

[0004] In the above technical solution, the impact force brought by mold stamping is reduced by the cooperation of structures such as fixed plate, connecting plate, sliding sleeve, and two sets of buffer springs. However, after injection molding, residue will be attached to the lower mold and needs to be cleaned before the next injection molding. During cleaning, it is necessary to bend over and insert your hands into the lower mold to wipe it, which results in a long cleaning time and cannot guarantee the cleaning effect. Therefore, a mold for camera housing is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a mold for a camera housing, comprising a base plate 1, a lower mold 2 fixedly connected to the top of the base plate 1, a bracket 3 fixedly connected to the top of the base plate 1, a cylinder 4 fixedly connected to the top of the bracket 3, an upper mold 5 fixedly connected to the output end of the cylinder 4, a cavity 6 formed in the inner wall of the lower mold 2, a loop tube 7 fixedly connected to the inner wall of the cavity 6, several sets of loop tubes 7 being arranged and evenly distributed within the cavity 6, each set of loop tubes 7 being connected through a vertical pipe, a connecting pipe 8 fixedly connected to the outer wall of the loop tube 7, a pump body 9 fixedly connected to the port of the connecting pipe 8, and the input end of the pump body 9 being connected to an external pipe to introduce tap water. The temperature of tap water provides a certain degree of heat dissipation for the lower mold 2. The surface of the lower mold 2 is provided with a mounting bracket 15. A handle 16 is fixedly connected to the outer wall of the mounting bracket 15. The handle 16 is convenient for the hand to hold and move the mounting bracket 15. A second set of sponge 17 is glued to the side of the mounting bracket 15 away from the handle 16. The surface of the mounting bracket 15 is provided with sponge 17. The sponge 17 can clean the surface of the lower mold 2 and can be coated with anti-rust oil, which is convenient for quick application to the inner wall of the lower mold 2. After the upper mold 5 is embedded, it can extend the service life of the mold. The surface of the lower mold 2 is provided with a guide component, and the surface of the mounting bracket 15 is provided with a positioning component.

[0033] Reference Figures 3-5 The pump body 9 is fixedly connected to the upper surface of the base plate 1. The guide assembly includes a sliding groove 10, which is opened on the upper surface of the lower mold 2. A ball bearing 11 is provided inside the sliding groove 10. The outer wall of the ball bearing 11 is adapted to the inner wall of the sliding groove 10. A support plate 12 is rotatably connected to the top of the ball bearing 11. The upper surface of the support plate 12 is on the same horizontal line as the upper surface of the lower mold 2, so as not to affect the embedding of the upper mold 5. The support plate 12 can slide back and forth in the inner wall of the sliding groove 10. The positioning assembly includes a positioning hole 13, which is opened on the upper surface of the support plate 12. A positioning post 14 is fixedly connected to the inner surface of the mounting bracket 15. The inner wall of the positioning hole 13 is adapted to the outer wall of the positioning post 14. The positioning post 14 can be inserted into the interior of the positioning hole 13 to quickly connect the mounting bracket 15 to the support plate 12.

[0034] Reference Figures 4-5 The outer wall of the mounting bracket 15 has a mounting groove 18. The inner wall of the mounting groove 18 is fixedly connected to a telescopic rod 19. The movable end of the telescopic rod 19 is attached to the side of the sponge 17 near the Velcro 21. The inner wall of the mounting groove 18 is fixedly connected to a spring 20. The telescopic force of the telescopic rod 19 and the spring 20 can ensure that the first set of sponges 17 is attached to the corner of the lower mold 2. The outer wall of the sponge 17 is fixedly connected to Velcro 21. The outer wall of the mounting bracket 15 is fixedly connected to Velcro 22. Velcro 21 and Velcro 22 are glued to each other, which facilitates the replacement of the sponge 17 inside the mounting bracket 15.

[0035] Working principle: Insert the positioning pin 14 into the positioning hole 13. At this time, the mounting bracket 15 moves the sponge 17 into the lower mold 2. Manually hold the handle 16 to move it. The support plate 12 is forced to move the ball bearing 11 inside the sliding groove 10, so that the sponge 17 can adhere to the inner wall of the lower mold 2 for wiping. After the sponge 17 has circled the lower mold 2, force is applied to the mounting bracket 15 to disengage the positioning pin 14 from the positioning hole 13. Then, the mounting bracket 15 is fully placed inside the lower mold 2 and moved back and forth. The second set of sponges... 17 is attached to the bottom of the lower mold 2 and wiped. After the inside of the lower mold 2 is cleaned, the injection liquid is poured into the lower mold 2. The cylinder 4 is started to drive the upper mold 5 to be embedded in the lower mold 2. After standing for a period of time, the pump body 9 draws in tap water and injects the water source into the multiple sets of loop tubes 7 through the connecting pipe 8. The pipe wall of the loop tube 7 is attached to the cavity 6 to conduct heat to the heat source. After the pump body 9 repeatedly draws out the heat-conducted water source, it injects room temperature tap water again, which shortens the cooling and molding time of the camera shell and ensures the mold production efficiency.

[0036] 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.
