Problems solved by technology

[0003] The injection mold needs to be demolded after the plastic melt is cooled and solidified. Generally, the demoulding part will be inserted into the mold cavity during the mold closing process, and the demoulding part is generally provided with barbs. When demoulding, Use the barb to pull out the plastic product, this structure is easy to cause damage to the plastic product during demoulding, thus increasing the defective rate

Abstract

The invention relates to a plastic injection mold. The plastic injection mold comprises a mold seat, a fixed mold body, a movable mold body and an injection nozzle. Two left rectangular guide slots and two right rectangular guide slots are separately formed in the left and right sides of the movable mold body; left guide posts and right guide posts are slidably mounted in the two left rectangular guide slots and the two right rectangular guide slots, separately; a left fixed arm and a right fixed arm are symmetrically and fixed arranged on the left and right sides of the lower end of the movable mold body; combined arms are fixedly arranged on the lower ends of the left fixed arm and the right fixed arm; a connecting groove is formed in the center of the upper end of the fixed mold body; the injection nozzle is mounted in the connecting groove; an injection cavity is formed in the fixed mold body; a main runner communicating to the connecting groove is arranged on the upper end of the injection cavity; and a rectangular injection matched cavity matched with the injection cavity is formed in the center of the upper end of the movable mold body. The plastic injection mold provided by the invention is simple in structure, stable to operate and reasonable in design, and the defective percentage can be decreased.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a plastic injection mold. Background technique [0002] Injection mold is a tool for producing plastic products; it is also a tool for giving plastic products a complete structure and precise dimensions. Injection mold is a device used in mass production of certain complex-shaped parts, specifically referring to plastic that is melted by heat. Machine high-pressure injection into the mold cavity in the injection mold, after cooling and solidification, the finished plastic product is obtained. [0003] The injection mold needs to be demolded after the plastic melt is cooled and solidified. Generally, the demoulding part will be inserted into the mold cavity during the mold closing process, and the demoulding part will generally be provided with barbs. When demoulding, The barb is used to pull out the plastic product. This structure is easy to cause damage to the plastic product dur...
