Problems solved by technology

Existing manual devices are labor-intensive in actual mass production, and the delayed curing time is controlled manually by watching the clock. The foaming density of the product is uneven, and it is difficult to control defects such as air bubbles and material shortages, resulting in low yield and large waste. Problems and deficiencies such as low efficiency, high cost of labor and material consumption, and poor consistency of product quality

Abstract

The invention discloses a pneumatic gasbag-type semi-automatic polyurethane foaming and molding device, which consists of a mold part, a pneumatic mold-closing and mold-locking part, a pneumatic sealing part, a rotary supporting part and an electrical control part. By adopting the technical scheme that a pneumatic air cylinder is controlled to automatically lock a mold and open or seal the air vent of the mold through a time sequence and the mold is opened and closed by using an upper gasbag and a lower gasbag, the problems of the conventional manual devices such as low rate of finished products, serious waste, low production efficiency, high labor cost and material cost, and poor consistency of the quality of products are solved. The provided pneumatic gasbag-type semi-automatic polyurethane foaming and molding device makes pneumatic foaming and molding production fulfill the aims of reducing labor intensity, improving the rate of finished products, reducing waste, improving production efficiency, decreasing labor cost and material cost and improving the consistency of the quality of the products through a time-controlled pneumatic semi-automatic operation mode.

Description

technical field [0001] The present invention relates to a foam molding device, specifically refers to a device for two-component polyurethane foam molding products, which utilizes an air bag to open and close the mold, and uses a time-controlled pneumatic cylinder to automatically lock the mold, open or block the exhaust port of the mold. Pneumatic air bag semi-automatic polyurethane foam molding device. Background technique [0002] The two-component polyurethane foam molding device of the prior art is a hand-molded mold device connected and opened by hinges, from mold opening, pouring, mold closing, mold locking, rotating mold, air blocking port, delayed curing , to open the mold and take out the whole production process of the product, all completed by manual operation. Existing manual devices are labor-intensive in actual mass production, and the delayed curing time is controlled manually by watching the clock. The foaming density of the product is uneven, and it is dif...
