Description

technical field

[0001] The invention relates to the technical field of manufacturing automobile interior decoration products, in particular to a cold forming mold for automobile carpets. Background technique

[0002] Car carpets are installed on the floor of the vehicle's inner compartment to play the role of shock absorption, noise reduction, heat insulation, etc., and are the main products of automotive interior parts. The production process of traditional car carpets includes blank heating, pressing, cutting, trimming and other processes. Because thermoforming consumes a lot of energy and is prone to deformation and other problems, some car carpets use cold forming technology. The existing automobile carpet cold forming mold includes upper mold base, upper mold, lower mold, lower mold base, binder plate and cooling water pipe, etc., wherein the binder plate is connected with the upper mold or lower mold by screws. The forming mold uses a pressing plate to press the blank...
