Description

Technical Field

[0001] The utility model relates to the technical field of elastic foam material molding and processing, in particular to an elastic foam material molding device. Background Art

[0002] Polyurethane rigid foam is a high molecular polymer made of isocyanate and polyether as the main raw materials, mixed with a variety of additives such as foaming agent, catalyst, flame retardant, etc. through special equipment, and foamed on-site by high-pressure spraying. There are two types of polyurethane foam: soft foam and hard foam. Soft foam has an open-cell structure, and hard foam has a closed-cell structure. In the molding process of polyurethane elastic foam materials, traditional equipment has low processing efficiency, complex demoulding structure, and inconvenient material collection.

The utility model designs a molding device for polyurethane elastomer foam material, and the hydraulic telescopic rod drives the extrusion plate to extrude the raw material and extrude extrusion holes to enter multiple shaping cylinders for shaping. When one end of the shaping cylinder moves to the inside of the socket, the molded material will fall into the discharge trough under the action of the demolding baffle, and finally be collected by the collection frame, so that multiple polyurethane elastic foam materials can be extruded at one time, and demolding is convenient and collection is convenient, which improves the molding production efficiency of the polyurethane elastic foam material, and effectively solves the problem of low efficiency and inconvenience in demolding and collection during the molding process of the polyurethane elastic foam material.

[0004] However, the volume of the molding device of the elastomeric foam material is too large, and it occupies a large area when in use. At the same time, when demolding and unloading, the demolding baffle is used for limiting, and the shaping cylinder is moved to separate the elastic material from the shaping cylinder and fall into the unloading trough. However, it is not considered that the other end of the elastic material is in the extrusion hole, which can easily cause the other end of the finished product to be damaged during the unloading process.
