[0002] Injection molding is a method for producing industrial products. Rubber and plastic injection molding are commonly used. Injection molding can be further categorized into compression molding and die casting. An injection molding machine is the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting materials using plastic molding molds. Injection molding is accomplished using an injection molding machine and molds.

[0003] Copy paper holders are generally produced by injection molding. During the injection molding process, in order to speed up the molding of the holder, the mold is cooled. Generally, water is sprinkled on the mold surface to cool the mold. However, the mold cannot be cooled at the same time, which affects the cooling effect of the mold.

The outer ring of the I-shaped wheel is wrapped with a pull rope 29. The other end of the pull rope 29 is connected to the push plate 27. Through the setting of the rotating motor 28, the rotation of the rotating motor 28 can drive the I-shaped wheel connected thereto to rotate. The rotation of the I-shaped wheel causes the pull rope 29 to separate from it or rewrap around its surface. The pull rope 29 can drive the push plate 27. Move, the middle parts of the left and right ends of the mold body 9 are provided with holes and grooves, and the push plates 27 are adapted to the inner cavity of the holes and grooves.

[0026] A liquid inlet is provided on one side of the top of the right mold 19, and a sealing plug 20 is clamped in the inner cavity of the liquid inlet. The material of the sealing plug 20 is metal iron. Through the setting of the material of the sealing plug 20, the electromagnet 14 can be connected to the sealing plug 20 when powered on. The electromagnet 14 can drive the sealing plug 20 to separate from the liquid inlet, which is convenient for injection molding.

[0027] Working principle: When in use, the transmission structure drives the mold body 9 to move. When the mold body 9 moves to the injection position, the electromagnet 14 contacts the top of the sealing plug 20 under the action of the electric telescopic rod 12 and the electric telescopic rod 2 13. The electromagnet 14 is energized, and the electromagnet 14 and the sealing plug 20 are magnetically attracted. At this time, the bottom of the injection tube 17 contacts the top of the mold body 9, and the electric telescopic rod 2 13 contracts. The electric telescopic rod 2 13 drives the sealing plug 20 to separate from the liquid inlet through the electromagnet 14. The electric telescopic rod 12 contracts, and the electric telescopic rod 12 drives the sealing plug 20 and the injection tube 17 to move. The sealing plug 20 moves away from the liquid inlet, and the injection tube 17 gradually approaches the liquid inlet. When the injection tube 17 moves to the top of the liquid inlet, the injection molding machine body 7 works, and the injection molding machine body 7 injects the injection liquid into the inner cavity of the mold body 9 through the injection tube 17. After the injection is completed, the electric telescopic rod The retracted rod 12 is extended, and the sealing plug 20 is moved to the top of the liquid inlet again. The electric telescopic rod 2 is extended, and the electric telescopic rod 2 is driven by the sealing plug 20 to engage with the liquid inlet. The electromagnet 14 is powered off, and the hydraulic telescopic rod 10 is extended. The hydraulic telescopic rod 10 drives the injection mold body 9 connected thereto to move into the coolant. The mold body 9 is cooled in the coolant, and the transmission structure drives the mold body 9 to move. After the mold body 9 is cooled, when demoulding is required, the mold body 9 moves to the outside of the water tank 1 under the action of the transmission structure and the hydraulic telescopic rod 10. The air compressor 22 and the rotary motor 1 24 and the rotary motor 2 28 are all working. The operation of the rotary motor 28 separates the pull rope 29 from the I-wheel, and the rotation of the rotary motor 1 24 separates the right mold 19 and the left mold 18. The operation of the air compressor 22 causes the push plate 27 to extrude the injection molded part, and the injection molded part and the mold body 9 can be quickly separated.
