Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1 to Figure 5 As shown, the side core-pulling injection mold of the present invention includes a fixed mold 1 and a movable mold 2, the movable mold 2 is provided with a lower cavity, the lower cavity is fixed with a core 3, and the fixed mold 1 is provided with an upper cavity , after closing the mold, the upper and lower cavities are closed to form a complete cavity. More specifically, the fixed mold is formed by screwing the upper fixed mold seat plate and the lower fixed template, and the upper cavity is located on the lower surface of the fixed template. The movable mold 2 of the present embodiment is formed by screwing the movable mold seat plate 2.1, the spacer 2.2, the backing plate 2.3 and the movable template 2.4 from bottom to top; the core 3 is screwed and fixed on the backing plate 2.3 and the passive templa...

Abstract

The invention discloses a side core-pulling injection mold, which includes a fixed mold and a movable mold, the movable mold is provided with a horizontal chute, and a core-pulling slider is slidably fitted in the horizontal chute, and a pointing core is arranged inside the core-pulling slider The side insert block; there is a hinge shaft on the outside of the core-pulling slider, and the swing rod is fitted in the gap on the hinge shaft. The end of the rod away from the hinge shaft is provided with a linkage pin; the side of the fixed mold is connected with a vertical rectangular frame through the protruding mounting block, and the linkage pin is slidingly fitted in the vertical rectangular frame; each vertical rectangular frame is formed by a T-shaped top pressure plate It is composed of a U-shaped frame, and an adjustment screw for changing the distance between the outer horizontal plate and the mounting block of the T-shaped top pressure plate to clamp or loosen the U-shaped frame is provided between the inner vertical plate of the T-shaped top pressure plate and the installation block. The mold can realize the adjustable side core pulling distance, and the time interval between side core pulling and mold opening can be adjusted.

Description

technical field [0001] The invention relates to the field of injection mold equipment, in particular to a side core-pulling injection mold. Background technique [0002] Plastic products have the advantages of high strength, light weight, and low price. They are widely used in various fields of daily life, and in many fields, such as automobile manufacturing, plastic products have largely replaced metal products under the demand for lightweight . At present, in the field of injection molding in my country, a large number of high-end injection molds with complex structures and long lifespans that can be formed at one time still need to be imported in large quantities every year. Therefore, the market prospects for the demand and application of the above-mentioned high-end molds are broad. [0003] Among the above-mentioned high-grade one-time molding molds, there is a type of side core-pulling injection mold that occupies a large share; the characteristic of this type of mol...
