[0019] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please refer to Figures 1-5, the technical solution of a schematic diagram of a rapid cooling mechanism for the EVA raw material disc embryo of the utility model: It includes a rotating disc 1, and a fixing frame 2 is arranged on the left side of the rotating disc 1. And a cooling mechanism 3 is vertically arranged on the top surface of the fixing frame 2. The other end of the cooling mechanism 3 extends to the lower end of the fixing frame 2. A plurality of die pads 4 are arranged on the rotating disc 1 in a circular array. And a mold 5 is arranged on each die pad 4. And each mold 5 is vertically aligned with the cooling mechanism 3 in sequence. A first coolant circulation pump is connected in series between each die pad 4 through an inlet and outlet pipe. The cooling mechanism 3 includes a cylinder fixing plate 31. And a cylinder assembly 32 is vertically arranged in the middle of the cylinder fixing plate 31. And a universal pressing assembly 33 is arranged at the lower end of the cylinder assembly 32. The lower end of the universal pressing assembly 33 is connected with a cooling plate 34. A second coolant circulation pump 35 is connected to the cooling plate 34 through an inlet and outlet pipe.

[0021] The cylinder assembly 32 includes a cylinder 321, and a universal joint 322 is arranged at the lower end of the cylinder 321.

[0022] The universal pressing assembly 33 includes a guide plate 331. And a plurality of guide holes 332 are opened through at the four corners of the guide plate 331. And a guide rod 333 and a spring 334 are movably sleeved in each guide hole 332. A plurality of stable sliding rods 335 are vertically arranged on the left and right sides of the top surface of the guide plate 331. And the other end of each stable sliding rod 335 penetrates through the cylinder fixing plate 31.

[0023] The rod diameter of the guide rod 333 is 1 - 1.5 cm smaller than the aperture of the guide hole 332.

[0024] The cooling plate 34 is of a hollow structure. An inlet 342 and an outlet 343 are respectively opened through on the side of the cooling plate 34. The cooling plate 34 has the same structure as the die pad 4.

[0025] Working principle:

[0026] First, when the rotating disc 1 rotates to shift an injected mold 5 under the cooling mechanism 3, the cylinder 321 descends. Through the universal pressing assembly 33, the cooling plate 34 descends to abut against the top surface of the mold 5. It should be noted that the top surfaces of each mold 5 are not on the same horizontal plane. Therefore, when the cooling plate 34 abuts against the mold 5, due to the design that the rod diameter of the universal joint 322 and the guide rod 333 is 1 cm smaller than the aperture of the guide hole 332, the cooling plate 34 has a universal swinging function. Therefore, when abutting against the top surface of the mold 5, it will adapt to the top surface of the mold 5 to fit, maximizing the fitting surface. Then, the second coolant circulation pump 35 circulates to supply coolant to the cooling plate 34 to cool the upper end of the mold 5. And the lower end of the mold 5 circulates to supply coolant to the die pad 4 through the first coolant circulation pump for cooling, so as to quickly cool and shape the mold and improve production efficiency. When the cooling time is reached, the rotating disc 1 rotates a mold 5 pitch to carry out the next station work.
