Description

Technical Field

[0001] The utility model relates to the technical field of flat plate vulcanizing machine equipment, in particular to a vulcanizing molding device with a heat recovery function. Background Art

[0002] Vulcanization molding equipment is also called automatic tablet press, rubber vulcanizer, small tablet press and hot press molding machine. It is very suitable for mixing and processing of chemical raw materials such as polymers in the rubber and plastic industries and batching tests. Put plastic or rubber raw materials in the mold and sandwich them between the upper and lower heating plates. In order to shape the raw materials, pressure is applied under the heating plate to form the rubber plastic parts.

[0003] However, after the vulcanizer completes the vulcanization of rubber and plastic parts, the temperature of the electric heating plate is usually cooled slowly by natural cooling, which will cause energy waste. If the heat energy of the electric heating plate is recovered for other purposes, the heat energy of the vulcanizer can be fully utilized and the energy consumption of other processing processes can be reduced. Therefore, those skilled in the art hereby propose a vulcanization molding device with heat recovery function. Utility Model Content

[0029] like Figures 1 to 3 As shown, the utility model provides a vulcanization molding device with a heat recovery function, comprising a flat vulcanizer 1 erected on the ground and a heat recovery component 2 arranged at the back of the flat vulcanizer 1;

[0030] The plate vulcanizer 1 includes a base 11, guide rails 14 fixed at the four corners of the top surface of the base 11, and a hydraulic facility 13 mounted on the top of the guide rails 14, and a movable seat 15 that moves up and down along the guide rails 14 is connected to the hydraulic output shaft of the hydraulic facility 13, wherein a heating plate 16 is provided on the side of the movable seat 15 and the base 11 that are close to each other.

[0031] The heat recovery assembly 2 includes a water tank 21 and a water pump 22, and two hollow rectangular frames 25 sleeved on the outer surface of the heating plate 16, and a water outlet pipe and a water return pipe are arranged between the hollow rectangular frame 25, the water tank 21 and the water pump 22. The inside of the hollow rectangular frame 25 is hollow, and the material of the hollow rectangular frame 25 is brass, which is used to transfer the heat of the heating plate 16 to the aqueous solution in its inner cavity.

[0032] The water outlet pipe includes a water inlet pipe 23 connected to the water outlet port of the water pump 22 through a pipe joint, a water inlet bellows 24 penetrating the left side of the upper and lower hollow rectangular frames 25, and the end of the water inlet bellows 24 converging with each other and the end of the water inlet pipe 23 away from the water pump 22 are connected through a tee pipe 26. The water return pipe includes a water outlet bellows 27 penetrating the right side of the upper and lower hollow rectangular frames 25, and a water return pipe 28 penetrating from the top of the water tank 21, and the end of the water return pipe 28 away from the water tank 21 and the end of the water outlet bellows 27 converging with each other are connected through a tee pipe 26.

[0033] The water pump 22 is connected to the water tank 21 through a water pipe, and the top and right side of the water tank 21 are provided with circular holes for the return pipe 28 and the water pipe to pass through. A faucet is provided on the right side surface of the water tank 21 for the hot water in the water tank 21 to flow out. The four corners of the movable seat 15 are provided with bearings that slide with the guide rail 14. An electric control box 12 is provided on the side wall surface of the base 11 to control the overall operation of the plate vulcanizer 1.

[0034] According to the preferred technical solution provided above, the workflow of the solution is described as follows:

[0035] Under the setting of the electric control box 12, after the heating plate 16 is set to vulcanize the rubber workpiece, the water pump 22 starts to drive the water in the water tank 21 to circulate slowly. Therefore, when the heating plate 16 on the movable seat 15 and the base 11 gradually heats up to the vulcanization operation temperature and the workpiece is vulcanized, the water in the hollow rectangular frame 25 does not circulate, so as not to affect the normal vulcanization operation.

[0036] After the heating plate 16 completes the vulcanization of the rubber workpiece, the heating plate 16 is in a non-operating state, but its temperature will be transferred to the water inside the hollow rectangular frame 25 through the hollow rectangular frame 25, and the water pump 22 will draw water from the water tank 21, and inject cold water into the hollow rectangular frame 25 through the water inlet pipe 23 and the water inlet bellows 24. While the water inside the hollow rectangular frame 25 takes away the temperature, the water will also flow back into the water tank 21 from the water outlet bellows 27 and the water return pipe 28. Under the action of multiple cycles, the water inside the water tank 21 is heated, and the hot water can be used in other operations of industrial production.

[0037] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
