[0003] However, existing molds generally do not have a heating function when in use, so the temperature in the mold will be uneven during the production process of the protective cover. There is a temperature difference between the liquefied plastic that enters the mold first and the liquefied plastic that enters the mold later, which will cause uneven cooling of the protective cover and reduce the production quality of the protective cover.

[0020] As a technical optimization solution of the present invention, the installation component includes a screw 307, and the upper end of the screw 307 passes through the upper mold base 3 and is threadedly connected to a nut 301, which facilitates the disassembly of the upper module 305 and makes it easier for staff to inspect and repair the heating tube 308.

[0021] As a technical optimization solution of the present invention, the upper surfaces on both sides of the upper module 305 are fixedly connected to the limiting blocks 306, and the height of the limiting blocks 306 is greater than the diameter of the heating tube 308. The limiting blocks 306 can limit the distance between the upper module 305 and the upper mold base 3, and prevent the heating tube 308 on the upper surface of the upper module 305 from being squeezed and damaged when the upper module 305 is installed.

[0022] As a technical optimization solution of the present invention, a support frame 101 is provided on the outer side of the lower mold base 2, and the lower end of the support frame 101 is fixedly connected to the upper surface of the base 1, the lower surface of the support frame 101 is fixedly connected to the cylinder 302, and the lower end of the cylinder 302 is fixedly connected to the upper surface of the upper mold base 3, the inner surface of the support frame 101 is provided with a slide groove 102, and the inside of the slide groove 102 is slidably connected with an elastic telescopic rod 104, the side surface of the upper mold base 3 is provided with a limiting groove 309, and one end of the elastic telescopic rod 104 extends into the inside of the limiting groove 309, and the upper surface of one end of the elastic telescopic rod 104 is fixedly connected to a toggle plate 103, and the upper mold base 3 can be limited by the elastic telescopic rod 104 and the limiting groove 309, and the operation stability of the upper mold base 3 is improved, thereby avoiding misalignment between the upper mold base 3 and the lower mold base 2.

[0023] When the present invention is in use, the starter 304 is first turned on by the temperature controller 303. At this time, the starter 304 will heat the heating tube 308 on the upper surface of the upper module 305, so that the upper module 305 will be heated by the heating tube 308. Then the cylinder 302 on the lower surface of the support frame 101 is started, so that the upper mold base 3 is pushed to the lower mold base 2, and then the liquefied plastic is injected between the upper module 305 and the lower module 201 through the injection port 202. When the plastic enters between the lower module 201 and the upper module 305, the heating tube 308 heats the upper module 305, so that the liquefied plastic that enters between the upper module 305 and the lower module 201 at the front end will not be cooled first. When the liquefied plastic is full, the starter 304 and the heating tube 308 are turned off by the temperature controller 303. At this time, the liquefied plastic will be cooled at the same time, avoiding uneven cooling of the protective cover after injection molding.
