The working principle and the using process of the invention are as follows: when the plastic mold convenient for cooling forming is used, only ice blocks which can be dry ice are required to be placed in the ice box 8, then the ice box 8 is pushed into the cooling chamber 3, and then the feed liquid of the plastic product is poured into the plastic forming mold cavity 2, and because the bottom end of the plastic forming mold cavity 2 is positioned in the cooling chamber 3, the cold air generated by the ice blocks can accelerate the cooling forming of the feed liquid of the plastic product in the plastic forming mold cavity 2, so that the working efficiency is improved;

when an operator needs to push the ice box 8 into the cooling chamber 3, the bottom end of the ice box 8 is pushed into the cooling chamber 3 from the front surface of the base 1, the inner slide block 18 slides into the side slide groove 19, the ice box 8 can be pushed into the cooling chamber 3 smoothly until the end plate 7 is pushed into the end groove 17, the limit pin 4 is rotated downward forcibly, the top end of the hemispherical telescopic clamping block 10 is pushed into the spring groove 11, the bottom end of the limit pin 4 can be rotated to the front surface of the end plate 7, the top end of the hemispherical telescopic clamping block 10 is clamped into the hemispherical clamping groove 16 at the bottom of the round rod 9 under the action of the spring in the spring groove 11, then the rotary handle 5 is pinched and the threaded rod 12 is rotated clockwise, and the bottom end of the threaded rod 12 gradually pushes the extrusion block 13 to the front surface of the end plate 7, until the extrusion block 13 is tightly attached to the front surface of the end plate 7, the end plate 7 and the ice box 8 can be stably limited, so that the ice box 8 cannot slide in the subsequent use process, and simultaneously, cold air in the ice box 8 is not easy to leak, when the ice box 8 needs to be taken out and ice blocks need to be replaced, the rotary handle 5 is screwed anticlockwise, so that the extrusion block 13 is not tightly attached to the end plate 7, then the limiting pin 4 is forcibly rotated upwards, so that the bottom end of the limiting pin 4 can be rotatably removed from the front surface of the end plate 7, the top end of the hemispherical telescopic fixture block 10 is clamped into the hemispherical clamping groove 16 on the side surface of the round rod 9 under the action of the spring in the spring groove 11, so that the limiting pin 4 is limited, and the limiting pin 4 and the extrusion block 13 cannot cause any blockage to the end plate 7, at the moment, the ice blocks in the ice box 8 can be replaced only by directly pulling out the end plate 7 and the ice box 8 by holding the pull handle 6;

when the end plate 7 is pushed into the end groove 17, the top end of the clip gasket 14 is also squeezed into the inner portion of the clip groove 15, and when the end plate 7 is fixed and limited by the limiting pin 4 and the squeezing block 13, the top end of the clip gasket 14 is squeezed to deform and fills the inner portion of the clip groove 15, so that the cold air in the cooling chamber 3 cannot leak from the connecting gap between the end plate 7 and the end groove 17, thereby ensuring that the ice cubes in the ice box 8 are fully utilized, and when the clip gasket 14 is subsequently damaged and aged, only the end plate 7 and the ice box 8 need to be drawn out, then the top end of the clip gasket 14 is pinched and pulled outwards forcefully, so that the outer snap ring 23 is squeezed to deform and pulled out from the inner portion of the annular clip groove 24, the bottom end of the clip gasket 14 is squeezed to deform, and the inner clip 21 is moved out from the inner portion of the inner clip groove 22, can be smooth move out the bottom of returning shape seal ring 14 from the inside of gasket groove 20, thereby smooth will return shape seal ring 14 and pull down and change, follow-up when installing shape seal ring 14, only need to return the inside of the bottom forceful crowded gasket groove 20 of shape seal ring 14, and make interior dop 21 by the inside of crowded draw-in groove 22, and make outer snap ring 23 by the inside of crowded ring groove 24, the bottom card that will return shape seal ring 14 that can be smooth is in the inside of gasket groove 20, thereby accomplish the change of returning shape seal ring 14.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
