[0031] See also Figure 1-5This embodiment provides a technical solution based on the first embodiment: the cooling assembly 200 includes a water tank 201 and a refrigerator 202 installed on one side of the upper end surface of the workbench body 1. The refrigerator 202 can quickly cool the water in the water tank 201. The refrigerator 202 is arranged on one side of the water tank 201. A connecting pipe 1 203 is fixedly connected to one side of the water tank 201. One end of the connecting pipe 1 203 is connected to a serpentine cooling pipe 204.

An electric push rod 7 is fixedly installed between the four corners of the upper end surface of the upper mold 3 and the U-shaped bracket 2. The input end of the electric push rod 7 is connected to the power supply through an external cable. Positioning rods 8 are fixedly installed at the four corners of the lower end surface of the upper mold 3. Positioning slots 9 matching the positioning rods 8 are provided at the four corners of the lower mold 5. The mutual cooperation between the positioning rods 8 and the positioning slots 9 can limit and fix the upper mold 3 and the lower mold 5. A through groove is provided at the bottom of the L-shaped support plate 101 to facilitate the movement of the sliding rod 2 110.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, the electric push rod 7 is first started to drive the upper mold 3 to overlap with the lower mold 5, and the positioning rod 8 is inserted into the positioning slot 9, and then the molten rubber is poured into the feed port. After confirming that the cavity is full, the refrigerator 202 is started to cool the water tank 201, and the circulating pump 206 is started to pump the cooling water in the water tank 201 into the serpentine cooling pipe 204. The serpentine cooling pipe 204 exchanges heat with the lower mold 5, and then the water after heat exchange enters the water tank 201 through the connecting pipe 205 and is repeatedly cooled by the refrigerator 202, so as to quickly and evenly cool and dissipate the heat of the plastic part. The rotating handle 104 is turned to drive the cooling water in the water tank 201 to cool the plastic part. The transmission rod 105 at one end of the rotating rod 103 rotates, and the transmission rod 105 drives the ejector plate 6 at the top of the sliding rod 108 to move through the cooperation of the transmission rod 2 106. The ejector plate 6 moves and drives the sliding rod 2 110 to move in the sleeve 109. The sliding rod 2 110 drives the rack 115 to move while moving. Since the rack 115 is meshed with the driving gear 114, the driving gear 114 is driven to rotate. Through the mutual cooperation of the rack 115, the driving gear 114 and the damping bearing, the ejector plate 6 can be limited and locked, thereby effectively driving the ejector plate 6 to evenly eject the bottom of the plastic part.
