Problems solved by technology

[0003] Metal molds have a long manufacturing cycle and high growth costs, and the metal molds are heavy and difficult to move
Therefore, the research and development of new products will undoubtedly increase the cost, which is not conducive to the research and development of new products.
[0004] Gypsum molds are widely used molds due to their rich gypsum raw materials, low cost, simple operation, and short production cycle. However, they have the disadvantages of high hardness, easy damage under high pressure, poor heat dissipation, and easy bursting at high temperatures.
[0005] Cement mold has high hardness and is easily damaged when the pressure is high, and the heat dissipation is not good, the high temperature is easy to burst, and the molding is not precise
[0006] Dense, affecting the quality of blow molding products

Abstract

The invention discloses a glass reinforced plastic (GRP) blow mold. The blow mold comprises a mold body and a connecting insert which are fixedly connected with each other, wherein, the mold body consists of an upper mold and a lower mold of the same structure; a lower mold cavity is arranged on the lower mold; a cooling water chamber is arranged on the rear face of the lower mold cavity and is equipped with a water inlet and a water outlet; and a hard cooling water pipe is arranged at a mold closing edge of the upper end of the lower mold, and two ends of the water pipe respectively extend out of the mold body. The GRP blow mold is low in cost and is manufactured quickly.

Description

technical field [0001] The invention relates to a blow mold, in particular to a blow mold made of glass fiber reinforced plastic. Background technique [0002] According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. In the blow molding industry, metal molds, plaster molds and cement molds are used. [0003] Metal molds have a long manufacturing cycle and high growth costs, and metal molds are heavy and difficult to move. Therefore, the research and development of new products undoubtedly increases the cost, which is not conducive to the research and development of new products. [0004] Gypsum molds are also widely used molds due to their rich gypsum raw materials, low cost, simple operation and short production cycle, but they have the disadvantages of high hardness, easy damage under high pressure, poor heat dissipation, and easy bursting at high temperatures. [0005] Cement mol...
