Injection mold

Abstract

The invention discloses an injection mold. The injection mold comprises a fixed mold plate, fixed mold kernels, a movable mold plate, movable mold kernels, a mold core, an ejector sleeve, oil cylinders, a push plate, a bottom needle plate, a surface needle plate, a sliding block insert, a sliding block seat and a connecting rod mechanism, wherein a plurality of pairs of the fixed mold kernels and the movable mold kernels are arranged on the fixed mold plate and the movable mold plate, and a plurality of mold cavities are formed between each pair of the fixed mold kernel and the movable mold kernel; and actions of core pulling and pushing out of the mold are respectively controlled through the two groups of the oil cylinders, and the sliding block insert can slide out of the mold cavities like arcs through arc-shaped fit of the sliding block seat, the sliding block insert and the movable mold kernels during core pulling. By adopting the injection mold disclosed by the invention, injection molding of a plurality of products can be completed by closing the mold once while the finished product rate of the products is ensured, the production efficiency is greatly improved, market and production requirements are met, and the injection mold further brings a great deal of economic benefits to manufacturers.

Description

technical field [0001] The invention relates to a mold, in particular to an injection mold, which belongs to the technical field of molds for plastic processing. Background technique [0002] In our daily life, plastic products are widely used, such as some daily necessities in people's daily life, such as shampoo bottles, cosmetic bottles, etc. Plastic products have won unanimous praise from the public because of their advantages such as light weight and low production cost. Plastic products are all processed by injection molding machines and injection molds, because the shapes of the products to be injected are different, and the molds that need to be used are also different. Existing injection molds are composed of a fixed template, a fixed mold core, a movable template, a movable mold core, a core, and a guide rod. The fixed mold core and the movable mold core are respectively fixed on the fixed template and the movable template. A mold cavity is formed between the cor...

Problems solved by technology

But for some products with complex structure, such as attached figure 1 The bottle cap shown in , the bottle cap is installed on some large bottles containing shampoo, shower gel, etc. When injecting the bottle cap, it is first necessary to pull out the core in the arc-shaped bottle mouth H after opening the mold. Then eject the injection molded part, because the curved bottle mouth H that bends downward at the front end has high requirements on the angle and strength of the core pulling. It brings great difficulty, so in order to ensure the yield of this product, the existing molds in production can only process one product at a time, which can neither meet the market demand nor reduce the production efficiency
