[0007] The outer wall of the mold is provided with rectangular and spiral installation grooves equidistantly along its height direction, a cooling pipe matched with it is arranged in the installation groove, a shell is sleeved on the outer surface of the cooling pipe, and groove bodies are respectively provided on the shell corresponding to the upper and lower ends of the cooling pipe, and a water inlet joint body and a water return joint body connected to the end of the cooling pipe are respectively provided in the two groove bodies, and a detection device for controlling the position of the connecting rod is also provided on the bottom surface of the workbench.

[0008] Furthermore, the detection device includes a detection block and a proximity switch. Detection blocks are respectively provided at the upper and lower ends of the connecting rod. A groove is provided on the bottom surface of the workbench corresponding to the detection block at the upper end, and an L-shaped mounting frame is provided on the bottom surface of the workbench corresponding to the detection block on the lower side. Proximity switches are respectively provided on the groove and the L-shaped mounting frame at the corresponding detection blocks.

[0009] Furthermore, the two detection blocks are symmetrically arranged at the middle position of the connecting rod.

[0010] Furthermore, a second installation groove for connecting the cooling pipe is provided on the inner wall of the shell.

[0011] Furthermore, the first installation groove and the second installation groove are arc-shaped structures that cooperate with each other and are compatible with the cooling pipe.

[0012] The advantages of the utility model compared with the existing technology are:

[0013] 1. Through the use of the rectangular structure and spiral cooling pipe, the mold can be quickly cooled after hot pressing, and the formed product can be quickly cooled, avoiding a long waiting time;

[0014] 2. Under the action of the detection block and the proximity switch, the detection block can be driven to move toward the proximity switch during the up and down movement of the connecting rod. When it is close to the proximity switch, the detection distance is reached, so that the proximity switch is activated, thereby effectively detecting the up and down movement position of the demoulding mechanism, thereby improving the use efficiency of the device.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, a hot press machine for producing plastic tableware comprises a workbench 1, a mold 2 is arranged on the top surface of the workbench 1, a hot press plate 3 which can move up and down is arranged at the position corresponding to the mold 2, moving rods 10 which can slide up and down are arranged at both ends of the bottom surface of the mold 2, and a connecting rod 11 is arranged between the two moving rods 10;

[0022] The outer wall of the mold 2 is provided with rectangular and spiral mounting grooves 4 equidistantly arranged along its height direction, a cooling pipe 5 matched therewith is arranged in the mounting groove 4, a shell 6 is sleeved on the outer side of the cooling pipe 5, and groove bodies 7 are respectively provided on the shell 6 corresponding to the upper and lower ends of the cooling pipe 5, and a water inlet joint body 8 and a water return joint body 9 connected to the ends of the cooling pipe 5 are respectively provided in the two groove bodies 7, the water inlet joint body 8 is connected to an external power water source, and the water return joint body 9 is connected to a water storage cylinder through a pipeline, so that circulating cold water can be formed inside the cooling pipe 5, thereby quickly cooling the product after hot pressing. A detection device for controlling the position of the connecting rod 11 is also provided on the bottom surface of the workbench 1.

[0023] like Figure 2 As shown, the detection device includes a detection block 12 and a proximity switch 15. The detection blocks 12 are respectively provided at the upper and lower ends of the connecting rod 11. A groove 13 is provided on the bottom surface of the workbench 1 corresponding to the detection block 12 at the upper end, and an L-shaped mounting frame 14 is provided on the bottom surface of the workbench 1 corresponding to the detection block 12 at the lower side. Proximity switches 15 are respectively provided on the groove 13 and the L-shaped mounting frame 14 at the corresponding detection blocks 12, and a controller is also provided on the workbench 1 (not shown in the figure). The proximity switch 15 and the power input member for controlling the demolding mechanism are electrically connected to the controller through wires.

[0024] like Figure 2 As shown, the two detection blocks 12 are symmetrically arranged in the middle of the connecting rod 11.

[0025] like Figure 3 As shown, a second mounting groove 16 for connecting the cooling pipe 5 is also provided on the inner wall of the housing 6 .

[0026] like Figure 3As shown, the installation groove 1 4 and the installation groove 2 16 are arc structures that cooperate with each other and are compatible with the cooling pipe 5, so that the stability of the cooling pipe 5 during use can be ensured.

[0027] In specific use, the water inlet joint body 8 is first connected to the external power water source, and the water return joint body 9 is connected to the water storage cylinder through a pipeline, so that circulating cold water can be formed inside the cooling pipe 5. After the product is hot-pressed, the rectangular and spiral cooling pipe 5 can quickly cool the mold 2 and the hot-pressed product inside it, thereby avoiding a long waiting time before demoulding.

[0028] During the demoulding process, the moving rod 10 and the connecting rod 11 are driven to move upward, and at the same time, the upper detection block 12 is driven to move upward. When it moves to a position close to the proximity switch 15, the proximity switch 15 receives a detection signal. Under the action of the controller, the power input part of the demoulding mechanism is shut down, so that the up and down moving position of the demoulding mechanism can be effectively detected, thereby improving the use efficiency of the device.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
