Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane production technology, and in particular to an injection molding device for waterproof membrane production that facilitates demolding. Background Technology

[0002] Waterproof membrane is a seepage-proof material made from high-molecular polymers. It is widely used in construction, transportation, subways, tunnels, and engineering projects. Its main function is to prevent liquid leakage and gas evaporation. In rock engineering, waterproof membranes primarily serve as seepage prevention and isolation, but also provide reinforcement and protection. It is mainly used for seepage prevention in earth-rock dams, rockfill dams, masonry dams, concrete dams, tailings dams, sewage reservoir dams, canals, and storage ponds; for seepage prevention lining in subways, basements, and tunnels; for seepage prevention in highway and railway foundations; and in sanitary landfills in conjunction with geotextiles, bentonite waterproofing blankets, and other geosynthetic materials. The production of waterproof membranes requires the use of injection molding equipment.

[0003] Current waterproof membrane injection molding equipment has certain shortcomings in use. When demolding is required after injection molding, the waterproof membrane tends to stick to the inside of the mold, thereby reducing the demolding efficiency and production efficiency of the waterproof membrane. To address this issue, we propose an injection molding device for waterproof membrane production that facilitates demolding. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through its injection mold, support plate, electric telescopic rod, top support rod, and push plate, utilizes the electric telescopic rod to move the push plate up and down, thereby pushing and demolding the injection-molded waterproof membrane. Through its circulating cooling pipes, connectors, and control water valves, it can connect to external circulating cooling water to achieve water cooling of the injection mold, reducing the adhesion of the waterproof membrane and assisting in demolding. This facilitates rapid demolding of the injection-molded waterproof membrane and effectively increases the injection efficiency of the waterproof membrane. Attached Figure Description
