Generally, the two connectors are equipped with gaskets, rubber, silicone and PTFE. It has good performance, high sealing and easy installation. The size and specifications of the clamp are different according to the different equipment scenarios. Larger clamps are made of preforms for injection molding. However, after the existing preforms are formed, they need to cooperate with external cooling devices to achieve cooling, and the separation of the preforms needs to be done manually, and the automaticity is low.

[0026] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0029] See also Figures 1 to 5 The main structure of the device body includes an upper template 1 and a lower template 2. A clamping die 3 is provided on one side adjacent to the upper template 1 and the lower template 2. When the two clamping dies 3 are attached together, a completed clamp skin is formed. A grouting port 4 is connected to the top of the upper template 1. The grouting port 4 is connected to the inside of the clamping die 3.

[0030] In order to facilitate grouting, a convex card and a concave cavity are respectively provided on the adjacent sides of the upper template 1 and the lower template 2, and the concave cavity and the convex card are adapted to each other, thereby achieving enhanced sealing;

[0031] In order to leave a gap for grouting, an outer peripheral frame 5 is provided on the outer side of the upper template 1 and the lower template 2. The outer peripheral frame 5 is a hollow rectangular structure. The sides of the two outer peripheral frames 5 are connected to the upper template 1 and the lower template 2 with diagonal braces 6. Through the design of the diagonal braces 6, a gap is left between the upper template 1 and the outer peripheral frame 5 to facilitate grouting of external equipment.

[0032] In order to achieve spray cooling, the outer side of the outer frame 5 away from the template is connected with a hollow plate 13, the center of the hollow plate 13 is a hollow cavity, and a spraying part 14 is provided at the cavity position of the hollow plate 13, and the spraying part 14 is provided with a plurality of nozzles;

[0033] A liquid inlet 15 is connected to one side of the hollow plate 13, and the liquid inlet 15 is connected to the external cooling liquid through a pipeline. The pipeline part can also be connected to an external pump body. A plurality of leaks 16 are opened on the outside of the hollow plate 13 at the bottom, and the leaks 16 facilitate the overflow of the sprayed water.

[0034] See also Figure 1 , Figure 2 and Figure 5 In order to realize automatic pressing and separation, side plates 7 are arranged at both ends of one side adjacent to the two peripheral frames 5. The side of the side plate 7 away from the template is fixed to the external plate component. Side cavities 8 are opened at both ends of the side plate 7. A double-headed motor 12 is embedded in the center of the side plate 7. The two driving ends of the double-headed motor 12 penetrate the side plate 7 and are connected to threaded rods 9 through couplings. The ends of the threaded rods 9 are rotatably connected to the inner wall of the side cavity 8. The outer threaded sleeve of the threaded rod 9 is provided with a nut sleeve 10.

[0035] The outer periphery of the nut sleeve 10 is matched with the inner periphery of the side cavity 8, so that the nut sleeve 10 can be limited. The two nut sleeves 10 on the same side are symmetrically distributed. The two nut sleeves 10 are provided with a pull rod 11 on the side close to the template. The two ends of the pull rod 11 are designed with arc surfaces. The centers of the two ends of the pull rod 11 are provided with center holes. The two ends of the pull rod 11 are hingedly connected to the template and the nut sleeve 10. The hinge is realized by two side plates and a pin passing through the center hole. The two pull rods 11 on the same side are correspondingly symmetrically designed with the nut sleeve 10.

[0036] When the double-headed motor 12 is running, it can drive the two threaded rods 9 to rotate synchronously, and further through the adaptation and limitation of the nut sleeve 10 and the side cavity 8, the synchronous movement of the two nut sleeves 10 is achieved.

[0037] The above-mentioned components and electrical equipment are all existing technologies or existing feasible technologies. The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0038] How it works

[0039] When the preform production device for the clamp skin is needed, the double-headed motor 12 is started to drive the threaded rod 9 to rotate, so that the nut sleeve 10 moves toward each other synchronously, so that the pulling rod 11 moves synchronously, and the outer peripheral frame 5 and the upper and lower templates move toward each other, and the concave cavity and the convex clamp are matched to achieve fixation;

[0040] The external equipment inputs iron slurry through the grouting port 4 to fill the clamp concave mold 3. After the grouting is completed, the external pump body is started to allow the cooling water to spray and cool the upper and lower templates through the nozzle;

[0041] The cooled liquid overflows through the leak 16;

[0042] After cooling is completed, the double-headed motor 12 is started again to drive the threaded rod 9 to rotate, so that the nut sleeve 10 moves synchronously, so that the outer frame 5 and the upper and lower templates are separated from each other, thereby realizing automatic separation, taking out the shaped clamp skin, and completing the processing.
