Description

Technical Field

[0001] The invention relates to the technical field of sponge molding, and in particular to a sponge foaming molding and curing device. Background Art

[0002] Sponge foaming is a manufacturing process for producing porous elastic materials. The sponge foaming process mainly involves mixing and reacting specific chemical substances, and manufacturing sponges with porous structures through heating, expansion, curing and other steps. Therefore, sponges have good softness, elasticity and water absorption and are widely used in many fields. Due to the sponge foaming process, the typical sponge production adopts a one-step box foaming method. The raw materials are added to the forming box after high-speed stirring to complete chain growth, foaming, cross-linking, curing and other reactions to form a sponge product with a porous structure. Since a large amount of gas will be generated during the sponge foaming process, these gases will cause the sponge volume to expand rapidly. The sponge needs to be pressed to prevent it from deforming before solidifying and affecting the dimensional accuracy of the final product. In the existing technology, the sponge is mostly pressed by a pressing plate. During the pressing process, the sponge produces foaming or solidification reactions inside, and a small amount of sponge will adhere to the bottom of the pressing plate after the sponge processing is completed. At this time, the staff needs to clean the sponge residue at the bottom of the pressing plate. During this process, the staff may need to bend down and reach into the bottom of the pressing plate for cleaning. In this state, the staff may have a visual blind spot, which may make it difficult to clean the sponge residue at the bottom of the pressing plate, thereby affecting its subsequent use effect.
