[0003] However, during the injection molding process of the handlebar rear shell, since the handlebar rear shell has a certain curvature, the cycle for the rubber material in the cavity to cool and form the handlebar rear shell is prolonged, thereby increasing the production cost of the handlebar rear shell. Summary of the invention

[0004] In order to improve the production cost problem of a handlebar rear cover, the present application provides a handlebar rear cover mold.

[0006] A rear shell mold is provided in a direction, comprising an upper mold, a lower mold and a cooling device, wherein the upper mold is slidably connected to the surface of the lower mold, and a cavity for injection molding is formed when the upper mold and the lower mold are closed. An injection hole is provided on the surface of the upper mold away from the lower mold, and the injection hole is connected to the cavity. The cooling device comprises a cooling component, and the cooling component comprises a water inlet pipe, a guide pipe and a water outlet pipe. One end of the water inlet pipe is connected to an external water pipe, and the other end of the water inlet pipe is embedded in the lower mold and connected to the end of the guide pipe. The inclined height of the guide pipe increases as the distance to the cavity decreases. One end of the water outlet pipe is connected to the surface of the guide pipe, and the other end of the water outlet pipe protrudes from the surface of the lower mold. Water in the external water pipe passes through the water inlet pipe and the guide pipe in turn and is discharged from the water outlet pipe.

[0007] By adopting the above technical scheme, the water in the external water pipe passes through the water inlet pipe and the guide pipe in turn and is discharged from the water outlet pipe. The inclination height of the guide pipe increases as the distance to the cavity decreases. When the rear shell of the steering handle is processed, the upper mold and the lower mold are combined to form a cavity, and the rubber enters the cavity through the injection hole. The rubber and the cavity exchange heat, the inner wall of the cavity is heated, the inner wall of the cavity exchanges heat with the pipe surface of the guide pipe, the guide pipe is heated, the guide pipe is fully in contact with the water and exchanges heat, and the water is discharged from the water outlet pipe after heating, thereby achieving stable cooling of the inner wall of the cavity, accelerating the efficiency of cooling the rubber in the cavity to form the rear shell of the steering handle, shortening the production cycle of the rear shell of the steering handle, and thus reducing the production cost of the rear shell of the steering handle.

[0008] Optionally, the water outlet pipe separates the guide pipe into cooling section 1 and cooling section 2, wherein the cooling section 1 is close to the inner wall of the cavity, and the cooling section 2 is close to the inner wall of the injection hole.

[0009] By adopting the above technical scheme, the first cooling section is close to the inner wall of the cavity, and the second cooling section is close to the inner wall of the injection hole. The rubber is injected into the cavity through the injection hole, and the rubber transfers heat energy to the injection hole.

The second tube wall of the cooling section is heated up, and the second tube wall of the cooling section exchanges heat with water to achieve initial cooling of the rubber. The initially cooled rubber enters the cavity, and the inner wall of the cavity exchanges heat with the rubber. The inner wall of the cavity is heated up, and the inner wall of the cavity exchanges heat with the first tube wall of the cooling section.

The circulating impeller is coaxially connected to the end of the reciprocating screw rod 1 facing the water outlet end of the water outlet pipe, and the water discharged from the water outlet pipe impacts the circulating impeller blades and drives the circulating impeller to rotate.

[0017] By adopting the above technical solution, the water discharged from the outlet pipe impacts the circulating impeller blades, driving the circulating impeller to rotate. The circulating impeller is coaxially connected to the two ends of the reciprocating screw, driving the second reciprocating screw to rotate, driving the scraper to slide on the surface of the filter along the second axis of the reciprocating screw, and the scraping end of the scraper approaches the surface of the filter and scrapes away impurities, thereby achieving directional cleaning of the surface of the filter, thereby ensuring the stability of the filter in filtering water.

At the same time, an inner wall of the cavity is in full contact with the rubber material and heat exchange is performed. After the inner wall of the cavity is heated up, the heat energy is transferred to the pipe wall of the cooling section 1 3131.
