Technical Field

[0001] The utility model relates to the field of injection molding devices, in particular to an injection molding device for processing a battery cover. Background Art

[0002] The injection molding device is a device that integrates plasticizing, injection, cooling, and demolding functions. It uses the screw or plunger of the injection molding machine to heat and plasticize the plastic raw materials in the barrel, and then injects the molten plastic into the mold cavity through the injection device. After cooling and shaping, the battery cover product is obtained.

[0003] When using an injection molding machine to perform injection molding on the battery cover, the mold is first installed on the turntable of the injection molding machine, and then the injection molding machine is started to drive the injection molding component to slide downward on the top of the injection molding machine, so that the injection molding plate on one side abuts against the mold, and the battery cover raw material is injected into it for injection molding. After the processing is completed, the turntable is started to rotate to rotate the injected mold out, and at the same time, the other mold is rotated to the bottom of the injection molding component to continue the injection molding process. Since the battery cover just after injection molding is tightly fitted with the inner wall of the mold, it is difficult to remove it from the inner wall of the mold immediately, which increases the injection molding time and reduces the efficiency of the injection molding process.

[0020] The effect achieved by the above components is: by setting up protective blocks, several outlets of the air duct can be protected so that only the internal wind can be sprayed outward, and external dust is not easy to enter the interior of the air duct, avoiding blockage and affecting use.

[0021] The beneficial effects of the utility model are:

[0022] By setting an ejection device, when using an injection molding machine to perform injection molding on the battery cover, the mold will first be installed on the turntable on the injection molding machine, and then the injection molding machine will be started to drive the injection molding assembly to slide downward on the top of the injection molding machine, so that the injection molding plate on one side abuts on the mold, and the battery cover raw material is injected into it for injection molding.
