Description

Technical Field

[0001] The utility model relates to the technical field of pouring and foaming molding equipment, in particular to a pouring and foaming molding all-in-one machine. Background Art

[0002] In modern industrial production, pouring foam molding technology is widely used in the manufacture of various lightweight, high-strength foam plastic products, such as polyurethane foam and polystyrene foam, due to its high efficiency, energy saving and environmental protection. These foam plastic products play an important role in many fields such as construction, automobiles, home appliances, packaging, etc., and the market demand is huge.

[0003] The preparation of polyurethane damping foam elastic pads with high rebound performance usually also requires pouring foam molding preparation operations. The traditional pouring foam molding process is usually divided into two steps: first, various chemical raw materials are evenly mixed and injected into the mold; second, a chemical reaction and foaming occur in the mold, and finally a hard foam plastic product is produced. Although this process requires low investment and has great flexibility, it has disadvantages such as large raw material loss, low labor productivity, and potential unsafe factors in manual operation.

[0004] Currently, in order to achieve efficient production results, a pouring and foaming molding all-in-one machine is usually used to complete the production operation. Such pouring and foaming molding machines are generally equipped with corresponding feeding mechanisms, discharging mechanisms, and mixing mechanisms to achieve mixing and stirring using the mixing mechanisms. However, the top of such pouring and foaming molding machines is generally directly exposed to the outside. This direct exposure not only easily allows dust to enter and affect product quality, but also causes waste gas from the production process to be directly discharged into the processing workshop, polluting the air in the workshop and causing inconvenience to users. In view of this, we have proposed a pouring and foaming molding all-in-one machine. Utility Model Content
