Injection molding machine color changing method

Abstract

The invention discloses an injection molding machine color changing method. The method comprises inside color changing and outside color changing which are cooperated with each other. The inside color changing comprises steps of: a. preparing protection tools; b. cleaning a material pipe; c. preheating and drying the material pipe; d. forming a material semi-finished product; e. forming a material finished product; f. processing the material finished product; g. cooling the material pipe; and h. processing of a color changed finished product. The method reduces color changing time, increases the color changing efficiency, and saves the production cost.

Description

technical field [0001] The invention relates to a process flow of an injection molding machine, in particular to a method for changing the color of an injection molding machine. Background technique [0002] With the development of industrial technology, the refinement of machines and the refinement of division of labor, more and more workers are waiting or machine waiting time in the production process, and how to reduce waiting time and improve efficiency has always been the unremitting efforts of producers direction. [0003] The Chinese patent with the application number 200810216632.6 discloses the name "multi-color, multi-material high-gloss injection mold", which includes a fixed mold and a moving mold. Corresponding to each slideway, there are mold core sliders of different shapes, and there is a driving device for pushing the mold core slider into or out of the inner cavity of the movable mold through the slideway in the sea of ​​the movable mold. Start the drivin...

[0003] The Chinese patent with the application number 200810216632.6 discloses the name "multi-color, multi-material high-gloss injection mold", which includes a fixed mold and a moving mold. Corresponding to each slideway, there are mold core sliders of different shapes, and there is a driving device for pushing the mold core slider into or out of the inner cavity of the movable mold through the slideway in the sea of ​​the movable mold. Start the driving device to push out the previous core slider, and at the same time push the next core slider into the inner cavity of the movable mold for positioning. During this process, it takes a long time to start the driving device. The operation of the mold core slider can only wait, and the operator also needs to wait for a long time in this process, which results in extremely low work efficiency, which can not maximize the effective working time of the machine and equipment, and wastes the staff working hours, which undoubtedly brought huge losses to the enterprise and greatly increased the operating costs of the enterprise

Another example is the Chinese patent application No. 201010142967.5, which discloses an invention patent titled "Car Inner Handle and Its Two-color Injection Molding Method". The film is connected with the second injection molding system, and the mold is equipped with a rotating mechanism, which rotates 180 degrees, and the cavity of the body mold and the coating film is interchanged. The patent solves the problem of the structural strength of the product, but it involves more injection molding systems And its equipment, and each injection molding system and its equipment are operated according to the normal process when working, which has too much waiting time in the operation work, which invisibly increases the operating cost of the enterprise
