[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By passing the molten plastic into the interior of the lower mold, the output end of the pneumatic telescopic rod is pressed downward, and the movable plate drives the upper mold to move downward, and a convex block is provided at the bottom of the upper mold to press the ejector plate, so that the molten plastic will not drip into the interior of the installation groove. The engagement between the lower mold and the upper mold can shape the plastic product. The molten plastic transfers the temperature to the side wall of the lower mold. At this time, cooling water can be passed into the interior of the cooling groove through the water inlet, so as to cool the side wall of the lower mold. The cooling water can be evenly contacted with the outer side of the lower mold, so that the cooling of the lower mold can be more uniform, avoiding the residual molten plastic inside the lower mold caused by uneven cooling, and also making the plastic product after uniform cooling can be quickly taken out;

[0018] Furthermore, in order to prevent the cooling water from contacting the lower mold for a long time and causing its own temperature to rise, the cooling water can be cooled by the cooling coil, thereby effectively extending the use time of the cooling water. When the cooling water temperature rises, the cooling water is discharged and collected, and waits for secondary use after the temperature drops, reducing the waste of water resources;

[0019] 2. When cooling water is introduced to cool the lower mold, the water will pass through the filter. The filter can block some impurities from entering the cooling tank. At the same time, the filter at the other end can block scale to prevent scale from clogging other collection devices after being discharged with the cooling water. The threaded rod is rotated to drive the clamping plate to move to one side, so that the filter can be pulled up and down inside the installation box, thereby realizing the removal and cleaning of the filter, avoiding blockage in the state of long-term use, effectively increasing the cleanliness of the cooling water during use, and reducing impurities from entering the cooling tank.

[0020] Furthermore, when the lower mold and the upper mold are engaged, the pressing blocks at the four corners below the movable plate will press the pressing plate, so that the elastic airbag below the pressing plate discharges the gas inside it through the hose and transports it to the inside of the fixed rod, thereby pushing the piston rod inside the fixed rod, and the cleaning brush at one end of the piston rod is driven and rubbed against the filter, thereby cleaning the surface of the filter, thereby effectively extending the service life of the filter and avoiding the clogging of the filter during use that affects the cooling of the water inlet.
