[0034] The circular surface of the drain pipe 201 is fixedly connected with two fixed plates 210, one side of each of the two fixed rods is threadedly connected with a screw rod 211, one end of the screw rod 211 is fixedly connected with a pull plate 212, one side of the pull plate 212 is abutted with the filter plate 206, the pull plate 212 moves to press the filter plate 206, the pull plate 212 plays a role in improving the stability of the filter plate 206, one side of the drain pipe 201 close to the filter plate 206 is fixedly connected with a sealing strip 213, the other side of the sealing strip 213 is abutted with the filter plate 206, the filter plate 206 is pushed by the pull plate 212 to be attached to the sealing strip 213 for pressing, and the sealing strip 213 plays a role in improving the sealing performance between the filter plate 206 and the drain pipe 201.
[0035] As shown in Figure 5 and Figure 6 , the protection structure 3 comprises a support plate 31, the lower surface of the support plate 31 is fixedly connected with the base 1, the upper surface of the support plate 31 is fixedly connected with an inclined plate 32, the upper surface of the inclined plate 32 is fixedly connected with two guide plates 33, the lower surface of the inclined plate 32 is fixedly connected with a support rod 34, the lower surface of the support rod 34 is fixedly connected with the base 1, the inclined plate 32 is located below the moving module 9, the upper surface of the inclined plate 32 is fixedly connected with a buffer plate 35, the plastic part falls on the buffer plate 35 of the inclined plate 32, and the buffer plate 35 plays a role in buffering to avoid hard contact and breakage as much as possible.
[0036] Working principle: when the plastic parts need to be injection molded, the plastic particles enter the heating device 5 through the feeding device 6 to become fluid, the driving cylinder 8 drives the dynamic module 9 to adhere to the static module 7, then the plastic particles are pushed between the static module 7 and the static module 7 through the heating device 5, and a certain shape of plastic parts is formed through the concave-convex between them. At this time, the water source in the water tank 10 is guided into the water inlet pipe 11 by the driving of the water pump, and the water source in the two water inlet pipes 11 is in circular contact with the dynamic module 9, so that the dynamic module 9 is cooled, and at the same time the temperature of the plastic parts is reduced. When the circulating water enters the water tank 10 again through the water inlet pipe 11, the circulating water in the water tank 10 is cooled again by the fan and then recycled for use. However, the circulating water used for many times will produce some rust particles in the water inlet pipe 11, as well as impurities in the air and plastic particles.

Then, the inner groove 208 rotates the side plate 207, the iron rod 204 rotates the connecting plate 205 in the fixed frame 202, the filter plate 206 rotates to the side of the drain pipe 201 and is attached to the sealing strip 213 through the connecting plate 205, and then the two screw rods 211 are rotated. The screw rod 211 moves the pull plate 212 through the fixed plate 210, the pull plate 212 plays a role in improving the stability of the filter plate 206, the pull plate 212 extrudes the filter plate 206 and the sealing strip 213, and the sealing strip 213 plays a role in improving the sealing property between the filter plate 206 and the drain pipe 201, so that the filter plate 206 and the drain pipe 201 are sealed and limited. At this time, open the water outlet valve, and the circulating water used for many times is discharged through the drain pipe 201 in the water tank 10, while the rust particles are blocked by the filter plate 206. Through the blocking and filtering of the rust particles, the filtered circulating water can be normally discharged, reducing the degree of pollution.
[0037] When the plastic parts are not taken in time after injection molding and fall off, the plastic parts will fall off the buffer plate 35 after being separated from the static module 7, and the plastic parts will slide from the surface of the buffer plate 35 and the two guide plates 33 to the collecting frame, and the buffer plate 35 plays a role in buffering to avoid hard contact and cracking as much as possible, so as to effectively avoid the plastic parts from falling into the water tank 10 and causing water stains and oxidation.
