[0022] The cooling mechanism 6 is used to improve the molding efficiency of the product in the molding groove 501, thereby accelerating the production work. At the same time, the pushing mechanism 7 is used to improve the convenience of demoulding the molded product, thereby further improving the work efficiency.

[0023] Further Figure 1-4As shown, it is worth specifically explaining that the cooling mechanism 6 includes a cooling pipe 601, which is arranged in the lower template 5, and the cooling pipe 601 is fixedly connected with a water inlet pipe 602 at the front outer side of the lower template 5, and the cooling pipe 601 is fixedly connected with a water outlet pipe 603 at the rear outer side of the lower template 5, a first pump 605 is installed on the water inlet pipe 602, and a second pump 606 is installed on the water outlet pipe 603, the water inlet pipe 602 and the water outlet pipe 603 are arranged on the right side of the base 1 and are connected to a water collecting tank 604, and the cooling pipe 601 is arranged in a circular shape in the lower template 5 and is arranged around the molding groove 501.

[0024] By operating the first pump 605, the cooling water in the water collecting tank 604 is extracted and cooled through the cooling pipe 601, thereby cooling and molding the product in the molding groove 501. At the same time, by operating the second pump 606, the circulation of cooling water in the cooling pipe 601 is accelerated, thereby improving the cooling efficiency, thereby improving the molding efficiency and accelerating production.

[0025] According to the above working process, it can be known that: through the cooling mechanism 6, the electrical connector formed by the upper template 4 and the lower template 5 can be quickly and evenly cooled to improve its forming efficiency, thereby reducing the forming time and greatly improving the processing efficiency of the electrical connector.

[0026] Further Figure 1 and Figure 2 As shown, it is worth specifically explaining that the pushing mechanism 7 includes a connecting plate 701, which is movably arranged in the base 1 and arranged below the lower template 5. A top block 702 matching the forming groove 501 is fixedly connected to the top of the connecting plate 701, and fixed plates 703 are respectively fixedly connected to the front and rear sides of the connecting plate 701. A buffer pad 705 is fixedly connected to the bottom of the fixed plate 703. A slide bar 704 is penetrated and slidably arranged on the fixed plate 703.

After cooling and molding, the upper mold plate 4 is lifted by the cylinder 3. At this time, the connecting plate 701 and the top block 702 move upward under the elastic force of the spring 706, thereby realizing the ejection of the molded product in the molding groove 501, and improving the demoulding efficiency. The convenience of the demoulding process is improved.

[0028] This scheme has the following working process: when this device is used, the cylinder 3 is operated to make the upper template 4 press the product in the molding groove 501 to be pressed and formed, and the first pump 605 is operated to extract the cooling water in the water collecting tank 604 and cool the lower template 5 through the cooling pipe 601, so that the product in the molding groove 501 is cooled and formed, and at the same time, the second pump 606 is operated to accelerate the circulation of cooling water in the cooling pipe 601, thereby improving the cooling efficiency. At the same time, in the process of pressing the upper template 4 downward, the top block 702 moves downward in the molding groove 501, thereby pushing the connecting plate 701 to move downward, and the fixed plate 703 slides on the sliding rod 704 to squeeze the spring 706 to cause it to shrink. After cooling and forming, the upper template 4 is lifted by the cylinder 3. At this time, the connecting plate 701 and the top block 702 move upward under the elastic force of the spring 706, thereby realizing the ejection of the molded product in the molding groove 501, and improving the demolding efficiency.

[0029] In summary: by setting up the cooling mechanism 6, the electrical connector formed by the upper template 4 and the lower template 5 can be quickly and evenly cooled, so as to improve its molding efficiency, thereby reducing the molding time and greatly improving the processing efficiency of the electrical connector; by setting up the pushing mechanism 7, in cooperation with the cooling mechanism 6, the rapid cooling and molding can be achieved, and when the upper template 4 and the lower template 5 are separated, the finished product in the molding groove 501 can be removed, thereby improving the demolding efficiency of the product and greatly improving the convenience of demolding.
