Description

Technical Field

[0001] This utility model relates to the technical field of injection molds, and in particular to a mold for mass production of electrical switches. Background Technology

[0002] Electrical switches are an important part that protects the internal electrical components and provides physical support. They are produced by injecting molten plastic material into a mold for mass production and applying high pressure to solidify it. This method is suitable for producing electrical switch components with complex shapes and structures.

[0003] In the current injection mold manufacturing process, the mold can only be opened after it has cooled down. However, in some mass-produced injection molds, the heat dissipation capacity of the internal mold is generally lower than that of the external mold during the cooling process. The heat dissipation speed cannot be synchronized, which causes the switching components in mass production to not be able to be opened at the same time, affecting normal processing. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the current mass production mold for electrical switches, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a batch production mold for electrical switches, which solves the problem that "in the process of existing injection molds, the mold can only be opened after the mold has cooled down. However, in the process of cooling down some batch production injection molds, the heat dissipation capacity of the internal mold is generally lower than that of the external mold, and the heat dissipation speed cannot be synchronized, which causes the switch components produced in batches to not be opened at the same time, affecting normal processing".

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A mold for mass production of electrical switches, comprising:

[0009] The main unit includes a worktable. Two sets of limiting plates are fixedly connected to the upper surface of the worktable, and a moving plate is slidably connected between the limiting plates. An electric push rod is installed on one side surface of the moving plate, and a fixed plate is provided on the other side surface of the moving plate. The lower surface of the fixed plate is fixedly connected to the limiting plate, and multiple sets of fixed molds are fixedly connected to one side surface of the fixed plate.

[0010] The heat dissipation unit includes a fixed pipe fixedly connected to the surface of a fixed plate, a cooling pipe fixedly connected to the top input end of the fixed pipe, a support plate fixedly connected to the surface of the cooling pipe, one side surface of the support plate fixedly connected to the fixed plate, a water pump fixedly connected to the bottom input end of the cooling pipe, and the other end of the water pump fixedly connected to the bottom output end of the fixed pipe. A protective shell is fitted over the surface of the cooling pipe, and one side surface of the protective shell is fixedly connected to the fixed plate. A flow component is provided on the other side surface of the fixed plate.

[0011] As a preferred embodiment of the mass production mold for electrical switches described in this utility model, the flow component includes multiple sets of fans disposed inside the fixed mold, and the surfaces of the fans are all fixedly connected to connecting plates. The two sides of the multiple sets of connecting plates are respectively fixedly connected to the fixed plate and the protective shell.

[0012] As a preferred embodiment of the mass production mold for electrical switches described in this utility model, the fixing tube is designed in a grid pattern, and the inner wall surface of the fixing tube is closely fitted with the outer surface of the mold.

[0013] As a preferred embodiment of the mass production mold for electrical switches described in this utility model, the cooling tube is S-shaped, and gaps are provided on both sides of the cooling tube.

[0014] As a preferred embodiment of the mass production mold for electrical switches described in this utility model, the protective shell has two sets of ventilation slots on both the upper and lower sides, and a filter plate is fixedly connected inside each ventilation slot.

[0015] As a preferred embodiment of the mass production mold for electrical switches described in this utility model, the surface of the workbench is provided with a guide groove that cooperates with the fixed plate, and a guide plate is fixedly connected to the bottom surface of the inner wall of the guide groove, the guide plate being wedge-shaped.

[0016] The beneficial effects of this utility model are:

[0017] The power supply starts the water pump, causing the cooling water inside the fixed tube to flow to the cooling tube. Then, the cooling water flows from the output end at the top of the cooling tube into the input end of the fixed tube, thus achieving a circulation of cooling water between the fixed tube and the cooling tube. At the same time, the fixed mold, which is in close contact with the fixed tube, transfers heat to the cooling water inside the fixed tube, and then enters the cooling tube along with the flow of cooling water. Next, the power supply starts the fan, which accelerates the airflow on the surface of the cooling tube, thereby carrying away the heat inside the cooling tube. Finally, the cooled water is pumped back into the fixed tube by the power of the water pump. This not only synchronizes the heat dissipation capacity of multiple fixed molds, but also improves the overall heat dissipation capacity. Attached Figure Description

[0031] The flow component 206 includes multiple sets of fans 206a disposed inside the fixed mold 105, and the surfaces of the fans 206a are all fixedly connected to the connecting plates 206b.

[0032] Furthermore, the fixing tube 201 has a grid-shaped design, and the inner wall surface of the fixing tube 201 is in close contact with the outer surface of the fixed mold 105, so that the cooling water inside the fixing tube 201 can carry away the heat of multiple fixed molds 105.

At the same time, the fixed mold 105, which is in close contact with the fixed tube 201, transfers heat to the cooling water inside the fixed tube 201, and then enters the cooling tube 202 along with the flow of cooling water. Next, the fan 206a is started by power to accelerate the air flow on the surface of the cooling tube 202, thereby taking away the heat inside the cooling tube 202. Finally, the cooled water is made to flow back into the fixed tube 201 by the power of the water pump 203.
