Problems solved by technology

Due to the limitations of these process methods, the shortcomings are mainly manifested in: 1. The decoration effect is simplistic; 2. The production process is complicated and the efficiency is low, which makes the overall cost of the product higher; 3. Chemical solvents are used in the implementation process. Pollution to water, air, workers and the product itself, not environmentally friendly

Embodiment Construction

[0009] Injection molding process for in-mold inserts of the present invention comprises the following steps:

[0010] Step 1. Use ink to print the desired pattern on the substrate. The substrate used is ABS (acrylonitrile-butadiene-styrene copolymer) material with a thickness of 0.5 mm.

[0011] Step 2, forming the printed base material into the desired shape using positive pressure and vacuum; the specific realization process is as follows (shown in conjunction with the accompanying drawings):

[0012] The base material 6 is heated by the upper heating plate 5 and the lower heating plate 7, and after reaching the temperature required for thermoforming of the material itself, the base material 6 is moved to the forming area under the action of the conveying device. After arriving at the molding area, the upper mold 1 and the lower mold 3 are closed to form a closed space; the vacuum facility starts to work, and the vacuum is sucked through the vacuum port 4 at the bottom of th...

Abstract

The invention discloses a mould-embedded insert injection molding processing method which comprises the following steps of: printing a required pattern on a substrate by using ink; processing the substrate into a required shape by using a positive pressure-adding-vacuum method; putting the substrate into a mould to be ejected after superfluous edges are punched by using a punching mould. The invention has the advantages of rich decorative effect, high efficiency and low cost, meets the environmental requirements and is suitable for automotive interiors and the surface decoration of shells of household appliances.

Description

technical field [0001] The invention relates to a process method suitable for the surface decoration of automobile interior parts and home appliance shells, in particular to a process method for producing resin moldings with decorative surfaces by injection molding of in-mold inserts. Background technique [0002] At present, the surface decoration of automotive interior parts and the surface decoration of home appliance shells mainly adopts spraying, water transfer printing and other processes. Due to the limitations of these process methods, the shortcomings are mainly manifested in: 1. The decoration effect is simplistic; 2. The production process is complicated and the efficiency is low, which makes the overall cost of the product higher; 3. Chemical solvents are used in the implementation process. It pollutes water, air, workers and the product itself, and is not environmentally friendly. Contents of the invention [0003] The technical problem to be solved by the pr...
