Die for automobile carpet production and using method of die

Abstract

The invention discloses a die for automobile carpet production and a using method of the die. The die is driven by an external driving device to be subjected to die assembly, an internal space formedafter die assembly of the die is a cavity, a heating device is arranged in the die, circulating cooling pipes are arranged on the outer side of the die, a plurality of hollow grooves in divergent distribution are arranged on the inner cavity side wall of the cavity, the configuration mode of the circulating cooling pipes is the same as that of caulking grooves, a ceramic layer is arranged on the inner cavity side wall of each hollow groove, and metal parts are arranged on the surface of the ceramic layer; and when the driving device drives the die to be subjected to die assembly for press fitof a board, the metal parts expand in size under heating, and the hollow grooves are gradually filled and leveled up in the divergent direction in a saturated extrusion state. According to the die, air is discharged as far as possible by the divergent caulking grooves formed in the surface of the cavity, quality of produced products is improved, and the service life of the die is prolonged.

Description

technical field [0001] The invention relates to an injection mold, in particular to a mold used for the production of automobile carpets and its application method. Background technique [0002] The carpet on the car floor is called a molded carpet, which is a carpet production process. With this process, the carpet fits perfectly on the car floor without unevenness at all. The underbody of the car is bare metal, so there is usually an underlayment between the carpet and the metal floor, usually the underfill is made up of mass underlayment or polygon underlayment. Both are thicker, but Mass pads are thicker and have a rubber-like consistency, while Poly pads are lighter, thinner, and easier to handle. The texture, thickness and material of carpets are slightly different in production methods and models. There are mainly pile carpets, carpet rubber carpets, silk loop carpets, 3D three-dimensional guard room carpets, and pure wool carpets on the market. [0003] In the pro...

AI Technical Summary

Problems solved by technology

[0003] In the process of automobile carpet manufacturing, mold hot pressing is usually used, but in the process of mold pressing, due to the existence of certain drops and gaps on the surface of the mold, as well as the contact between the mold and the plate (usually a template) and the process of deformation of the plate , the air is not discharged in time, and the residue remains on the surface of the cavity of the mold, resulting in holes on the surface or inside of the produced carpet, which reduces the quality and life of the carpet
