Double-color mold with sequential slider drive mechanism

Abstract

The invention discloses a double-color mold with a sequential slider drive mechanism, which comprises two fixed mold plates, two movable mold plates, an ejector plate and an ejector rod, the fixed mold plates are positioned on the upper parts of the movable mold plates, and are provided with fixed mold inserts, the movable mold plates are provided with movable mold cavities, the cores of the fixed mold inserts and the movable mold inserts correspond to each other, and are formed into cavities along with sliders positioned on the sides of the tops of the movable mold plates, the movable mold plates, the ejector plate and the ejector rod are connected sequentially from the top down, the ejector plate is divided into two sections, the first section of ejector plate is positioned on the upperpart of the second section of ejector plate, and is provided with a stripping block set, the upper end of the stripping block set is contacted with the slider, the second section of ejector plate is provided with a push pin, one side of each fixed mold plate, which corresponds to the stripping block set, is also provided with a pressing block set, and the lower end of the pressing block set is contacted with the slider. The invention avoids the problem that products are injured due to the secondary action of the slider, thus increasing the yield, and meanwhile, the invention also overcomes the problem that the slider can shift due to centrifugal force when rotating along with the movable mold plates.

Description

technical field [0001] The invention relates to a sequential driving structure of primary and secondary sliders of a two-color mold, in particular to a two-color mold with a sequential driving mechanism of the sliders, and belongs to the technical field of mold manufacturing. Background technique [0002] At present, many plastic products are processed by injection molding. The appearance of plastic products is mainly determined by the surface requirements of the mold cavity, such as scratches, mirror polishing, etc., or later such as spraying, silk screen, etc. to improve the appearance. This method virtually increases the manufacturing process, increases the cost, and is not conducive to environmental protection. With the development of industry, the single-color injection molding in the past has developed into the current two-color and three-color injection molding. At the same time, the difficulty of mold injection molding has also increased, especially for products with...

Problems solved by technology

[0003] At present, in the market, the slider is generally opened after the first molding, and then pressed into it by the second closed mold. This will easily cause the slider to crush the product, making the product look bad and unacceptable to customers; there are also auxiliary devices to control the primary slider. After molding, it is in a closed state to secondary molding, but it is only suitable for sliders with short strokes and small inclinations, and cannot be widely used
