The new scheme can be coordinated by setting a bottom box, a double-headed threaded rod, a mold base and other devices, so that the device can easily limit and fix the mold base and the mold cover, avoid lifting the mold cover when the device is injecting material, and affect the injection molding of the product, which is beneficial to the molding of the socket shell; by setting a lifting rod, a lifting plate, a mold base and other devices, the device can be easily demolded from the product in the mold, which is beneficial for the staff to take the product out of the mold and improve work efficiency.

[0032] The following combined Figures 1 to 4 , the workflow of the electrical appliance shell cover injection mold for accelerating product curing provided in this application is introduced.

[0033] In the first step, by starting the electric slide 5, the electric slide 5 slides on the slide rail 4, driving the connecting plate 6 and the upper mold 7 to move to the top of the lower mold 9. The telescopic tube 21 is stretched during the movement of the connecting plate 6, so that the injection molding material inside the material box 16 is injected into the lower mold 9 through the telescopic tube 21.

[0034] The second step is to start the motor 18. At this time, the output end of the motor 18 drives the first rotating shaft 19, the first pulley 22 and the stirring rod 20 to rotate. By rotating the stirring rod 20, the injection molding material inside the material box 16 can be stirred to avoid the solidification of the injection molding material. The first pulley 22 drives the belt 25 to move while rotating, so that the second pulley 24, the second rotating shaft 23 and the first bevel gear 26 rotate.

[0035] In the third step, by storing cold water in the second installation groove 8, the cooling of the lower mold 9 can be accelerated, and the electrical appliance shell cover inside the lower mold 9 can be quickly solidified. When the cold water in the second installation groove 8 is heated by the lower mold 9 and cannot cool the lower mold 9, the first water pump 13 and the second water pump 15 are started, so that the cold water in the water tank 11 can enter the second installation groove 8 through the second connecting pipe 14, and the hot water in the second installation groove 8 can enter the water tank 11 through the first connecting pipe 10, and the hot water can be cooled by the semiconductor cooling plate 12 arranged in the water tank 11.

[0036] It can be seen that the electrical appliance shell cover injection mold provided in the present application can achieve rapid cooling and solidification after the electrical appliance shell cover is injected. At the same time, the upper mold 7 and the lower mold 9 can be water-cooled and air-cooled to make the upper mold 7 and the lower mold 9 cool quickly. In the process of cooling the upper mold 7 and the lower mold 9, the injection molding material inside the material box 16 can also be stirred, thereby avoiding the injection molding material inside the material box 16 from solidifying, resulting in the phenomenon that the injection molding material cannot be used, which greatly facilitates the use of the staff.
