Embodiment Construction

[0008] The vacuum forming process of the female mold is a kind of female mold engraved with the pattern of the leather pattern, and the smooth film material is formed in the mold to form a leather-shaped skin in the shape of the interior part or the same station of the machine after the skin is made. The process in which the skin is vacuum adsorbed onto the substrate.

[0009] The raw materials used are skins with no skin texture on the surface, which can be PP-FOM skins, TPO skins, and TPU skins; first cut the skins according to the size of the interior parts to be processed, and then put the cut skins on the loading trolley , sent into the heating frame by the automatic feeding trolley, the heating frame moves to the heating box for heating, the heating temperature of the upper surface of the skin is 185°C±5°C, the heating temperature of the lower surface of the skin is 175°C±5°C, and the heating time is 30 Seconds, then the skin heating frame is sent into the forming hydrau...

Abstract

A vacuum molding technology for an automobile instrument-panel surface-skin female mold relates to processing technologies of automobile interior decorative parts, and mainly aims at solving the problems that skin lines are deformed or loss and the like by employing a conventional male mold vacuum molding technology. The above purpose is realized according to the following steps: selecting a raw material surface skin which does not have skin lines on the surface; putting the tailored surface skin on a charging table vehicle, sending to a heating frame via an automatic charging vehicle, moving the heating frame into a heating box for heating, then sending the surface-skin heating frame into a molding hydraulic machine which comprises an upper mold and a lower mold, processing the up-mold surface to form various skin lines or patterns, inserting into a mold bottom plate for locking through a mold-locking pin on the equipment, elevating the lower mold and the upper mold for molding under the driving force of the an oil cylinder, clamping the surface skin in the middle, forming a sealed cavity at the edge of the mold provided with a mold temperature control machine; closing the mold and vacuumizing, so as to form the skin lines and the profile through adsorption, cooling and sending to a demolding program. The technology comprises the advantages that there are not deep drawing and deformation loss of skin lines.

Description

Technical field: [0001] The invention relates to a processing technology of an automobile interior trim part, in particular to a female mold vacuum forming technology capable of processing skin textures or patterns while the skin of an automobile instrument panel is formed in a mould. Background technique: [0002] For mid-to-high-end models, the skin molding of interior parts (including instrument panels, door inner panels, etc.) is an indispensable process. At present, the male mold vacuum forming process is commonly used, that is, the skin with skin texture is used, and the male mold is vacuum-absorbed by heating, and the skin is adsorbed on the mold to obtain the desired shape or composited on the substrate. Get the products you need directly. Its shortcoming is that the existing epidermis with skin pattern is single, and in addition, when vacuum forming on the sun, the skin texture at the position with high stretching height is deformed or lost, which seriously affects...
