Description

Technical Field

[0001] This utility model relates to the technical field of molds, specifically to rapid cooling molds. Background Technology

[0002] Injection-molded phone casings are an indispensable component in modern smartphone manufacturing. They are produced through an injection molding process, which involves injecting molten plastic material at high temperatures into a mold, where it cools and forms the desired casing shape.

[0003] The mobile phone casing is produced by molding. Demolding is the last part of the mobile phone casing molding process. It mainly separates the dried mobile phone casing from the mold core to prevent the mobile phone casing from sticking to the surface of the mold core or remaining in the conical clamp during demolding. This would affect the next demolding process, cause blockage of the conical clamp, and reduce the yield.

[0004] Currently, there are many types of shell removal equipment on the market, but during the glue removal process, the phone shell often sticks to the inner wall of the mold or the outer wall of the mold column. In mass production, operators cannot quickly separate individual sticky cases, which leads to reduced production efficiency. Therefore, an easily separable mold is needed. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling mold, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid cooling mold, including a workbench, wherein a through hole is provided on the upper surface of the workbench, and a cooling mold fixedly connected to the lower surface of the workbench is provided below the through hole;

[0007] A ventilation pipe is fixedly connected to the lower surface of the cooling mold. A valve is fixedly connected to one end of the ventilation pipe near the cooling mold, and an air pump is fixedly connected to the other end of the ventilation pipe. The air pump is fixedly connected to the lower surface of the workbench.

[0008] Four support rods are fixedly connected to the upper surface of the workbench, and a support plate is fixedly connected to the upper surface of the support rods.

[0009] The lower surface of the support plate is fixedly connected to a storage bin, the lower surface of the storage bin is fixedly connected to a feed pipe, and the plate also includes an extrusion column. The end of the feed pipe away from the storage bin is fixedly connected to the upper surface of the extrusion column, and the upper surface of the extrusion column has a slot with the same size as the opening of the feed pipe. A discharge port is formed at the bottom of the slot, and a side opening communicating with the discharge port is formed at the bottom of the extrusion column.

[0010] Optionally, a gap is left between the extrusion column and the cooling mold.

[0011] Optionally, a dust cover is snapped onto the upper surface of the workbench, and the upper surface of the dust cover has a through hole that is slidably connected to the support rod. The extrusion column is fixedly installed inside the dust cover.

[0012] Optionally, four support columns are fixedly connected to the upper surface of the dust cover, a tray is fixedly connected to the upper surface of the support columns, an electric push rod is fixedly connected to the upper surface of the tray, and the electric push rod is fixedly connected to the lower surface of the support plate.

[0013] Optionally, the upper surface of the support plate is provided with a feed inlet, and a dustproof plate is snapped onto the upper surface of the feed inlet.

[0014] Optionally, a support frame is fixedly connected to the lower surface of the workbench.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] I. This utility model delivers air into a cooling mold, where the incoming air moves upward along the inner wall of the mold, thereby causing the cooled mobile phone casing to detach from the mold. By using gas for demolding, the mobile phone casing film can be protected from damage to the maximum extent, and demolding efficiency can be improved, ensuring the product qualification rate.

[0017] Furthermore, the evenly distributed discharge ports allow the solution to enter the gaps more uniformly, making the phone casing film more uniform. This prevents uneven thickness distribution of the phone casing film from causing different cooling efficiencies, which could damage the phone casing during demolding and improve the efficiency of finished products.

[0018] Second, this utility model can prevent uncooled solution from coming into contact with impurities in the air through the dust cover, thereby preventing contamination of the mobile phone casing film solution, making the mobile phone casing film purer and improving the product qualification rate.

Detailed Implementation

[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. Example 1

[0026] Please see Figures 1 to 5 The present invention provides a technical solution: a rapid cooling mold, including a workbench 1, a through hole on the upper surface of the workbench 1, and a cooling mold 14 fixedly connected to the lower surface of the workbench 1 below the through hole.

[0027] A ventilation pipe 19 is fixedly connected to the lower surface of the cooling mold 14. A valve 20 is fixedly connected to one end of the ventilation pipe 19 near the cooling mold 14, and an air pump 12 is fixedly connected to the other end of the ventilation pipe 19. The air pump 12 is fixedly connected to the lower surface of the workbench 1.

[0028] More specifically, in this embodiment, after the liquid solution has cooled and solidified in the cooling mold 14, the valve 20 is opened, and the air pump 12 is activated. The air pump 12 pumps air into the cooling mold 14 through the ventilation pipe 19. The incoming air moves upward along the inner wall of the cooling mold 14, thereby causing the cooled mobile phone casing to detach from the mold. By using gas to demold the mobile phone casing, the film on the mobile phone casing can be protected from damage to the maximum extent, and the demolding efficiency can be improved, ensuring the product qualification rate.

[0029] Furthermore, in this embodiment, four support rods 5 are fixedly connected to the upper surface of the workbench 1, and a support plate 7 is fixedly connected to the upper surface of the support rods 5.

[0030] The lower surface of the support plate 7 is fixedly connected to the storage bin 10, the lower surface of the storage bin 10 is fixedly connected to the feed pipe 11, and also includes an extrusion column 15. The end of the feed pipe 11 away from the storage bin 10 is fixedly connected to the upper surface of the extrusion column 15, and the upper surface of the extrusion column 15 is provided with a slot 18 that is the same size as the opening of the feed pipe 11. A discharge port 17 is provided at the bottom of the slot 18, and a side passage 16 communicating with the discharge port 17 is provided at the bottom of the extrusion column 15.

[0031] A gap 21 is left between the extrusion column 15 and the cooling mold 14.

[0032] More specifically, the liquid solution is stored in the storage bin 10 and then enters the slot 18 of the extrusion column 15 through the feed pipe 11. The solution in the slot 18 enters the side opening 16 through the discharge port 17 and then flows into the gap 21, thus completing the purpose of filling the mold with solution.

[0033] Furthermore, the evenly distributed discharge port 17 allows the solution to enter the gap 21 more evenly, making the mobile phone casing film more uniform. This prevents the mobile phone casing film from having different cooling efficiencies due to uneven thickness distribution, thus avoiding damage to the mobile phone casing during demolding and improving the efficiency of finished products. Example 2

[0034] Based on the above embodiment, a dust cover 2 is snapped onto the upper surface of the workbench 1, and a through hole is opened on the upper surface of the dust cover 2 to be slidably connected to the support rod 5. The extrusion column 15 is fixedly installed inside the dust cover 2.

[0035] More specifically, in this embodiment, the dust cover 2 that is snapped onto the workbench 1 can prevent the uncooled solution from coming into contact with impurities in the air, thereby preventing contamination of the mobile phone casing film solution, making the mobile phone casing film purer and improving the product qualification rate. Example 3

[0036] Based on the above embodiments, four support columns 3 are fixedly connected to the upper surface of the dust cover 2, a tray 4 is fixedly connected to the upper surface of the support columns 3, an electric push rod 6 is fixedly connected to the upper surface of the tray 4, and the electric push rod 6 is fixedly connected to the lower surface of the support plate 7.

[0037] More specifically, in this embodiment, when it is necessary to lift the extrusion column 15, the electric push rod 6 is activated, the electric push rod 6 drives the tray 4 to move, the tray 4 drives the dust cover 2 to move through the support column 3, and the movement of the dust cover 2 drives the extrusion column 15 to move, which reduces the amount of manual labor and improves work efficiency. Example 4

[0038] Based on the above embodiments, a feed inlet 9 is provided on the upper surface of the support plate 7, and a dustproof plate 8 is snapped onto the upper surface of the feed inlet 9.

[0039] More specifically, in this embodiment, the feed inlet 9 fixedly connected to the upper surface of the support plate 7 is provided with a ramp, which can allow the solution to enter the storage bin 10 better. The dustproof plate 8 snapped above the feed inlet 9 can effectively protect the solution raw material from contact with impurities in the air and protect the purity of the raw material.

[0040] Furthermore, in this embodiment, a support frame 13 is fixedly connected to the lower surface of the workbench 1.

[0041] The support frame 13 under the workbench 1 allows the mold to adapt to more locations, improving the mold's practicality and operability.
