Polyurethane foaming module capable of automatically removing excess materials

Abstract

The invention relates to a polyurethane foaming module capable of automatically removing excess materials. The foaming module comprises a bottom frame, a bottom mold erected on the bottom frame and atop frame, wherein a top mold is installed on the top frame, a pushing mechanism is used for pushing the bottom mold and the top mold to complete mold closing and mold opening, two guide rails are symmetrically arranged on the outer side of the bottom mold, moving parts are movably installed at tops of the guide rails, racks are arranged at bottoms of the guide rails, bottom columns are installedon the moving parts, and a driving mechanism is further installed on the moving parts. The foaming module is advantaged in that after module production completion, the arranged driving mechanism drives a transmission gear to rotate so that the transmission gear transversely moves along the rack, and the moving parts are pushed to transversely move along the guide rails, the tensioning assembly isdriven by the top frame to drive a scraper knife to move along a top edge of the bottom mold, residual materials left on the bottom mold can be quickly shoveled out through the scraper knife, the moldcan complete the next pouring procedure, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing, in particular to a polyurethane foaming module for automatic removal of excess material. Background technique [0002] Polyurethane elastomers are used for rollers, conveyor belts, hoses, auto parts, shoe soles, synthetic leather, wires and cables, and medical artificial organs, etc. Soft foams are used as pads for vehicles, homes and clothing, and hard foams are used for Thermal insulation, sound absorption, packaging, insulation and low-foaming synthetic wood. [0003] During the production process of polyurethane foam products, the polyurethane material needs to be poured into the corresponding mold. During the molding process, the gap after the mold is closed will have residual material overflowing. Affected by gravity, the residual material will accumulate in the bottom mold. In the edge area, after production, the staff need to manually remove the remaining material with ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the technical problems existing in the prior art, the present invention provides a polyurethane foaming module that automatically removes excess material to solve the problem that in the above molding process, excess material overflows in the gaps after the molds are closed, and is affected by gravity. The material will accumulate in the edge area of ​​the bottom mold. Therefore, after production, the staff need to manually remove the remaining material with a knife or hand. The manual cleaning efficiency is low. If the remaining material is not clear, it will easily affect the normal production of subsequent products.
