Problems solved by technology

[0002] In the existing mold for producing soles, in order to eliminate the resistance of the gas due to the foaming displacement of the EVA (ethylene-vinyl acetate copolymer) material after thermal expansion, the mode of punching holes on the mold has been adopted, although the resistance of the gas has been solved. , but due to the existence of air holes, the formed product has a physical appearance, which affects the appearance of the finished product. Some products also become waste products due to poor exhaust and incomplete molding, and the production efficiency is low; in addition, in the mold After using for a period of time, there will be a situation where the air holes are blocked and the air holes need to be re-drilled. Because the mold has many air holes, it is easy to cause deformation and rupture of the mold, which shortens the service life of the mold.
The molding of the product requires the mold to be heated to above 150°C and cooled to below 20°C. Generally, the heat is transferred to the mold through the heat conduction plate to heat it. The thickness of the mold greatly affects the heating time, and the heating is through external heating. Prone to uneven heating
Cooling generally uses room temperature water to shower the mold shell, but due to the influence of air temperature and water temperature, the cooling time is long, the product setting effect is unstable, the water cannot be recycled, the cost is high, the efficiency is low, and there are certain unfavorable factors for environmental protection. , which will prolong the overall production time

Abstract

The invention discloses an efficient shoe sole mold integrating heating and cooling. The efficient shoe sole mold integrating heating and cooling comprises an upper mold plate and a lower mold plate; a mold core is arranged on the inner surface of the upper mold plate; a mold cavity is formed in the inner surface of the lower mold plate; the mold core and the mold cavity are detachably installed on the upper mold plate and the lower mold plate correspondingly; the outer surfaces of the upper mold plate and the lower mold plate are each detachably connected with a heating and cooling plate; the inner surface of each heating and cooling plate is provided with a heating and cooling channel performing back and forth parallel circulating; one end of each heating and cooling channel is connected with an inlet, and the other end of each heating and cooling channel is connected with an outlet; each heating and cooling channel is covered with a heat conduction partition plate; and sealing rings are arranged on the edges of the heating and cooling channels in a surrounding manner. According to the efficient shoe sole mold integrating heating and cooling, by means of the heating and cooling plates which are detachably connected, the purposes that fast heating and cooling are performed on the formed surface of the mold, the structure is simple and easy to make, the manufacturing cost is low, the sealing worry is avoided, and popularization is easy are achieved, the manufacturing period is shortened, the production efficiency is improved, and the production cost is greatly lowered.
