Description

Connector injection mold convenient to drawing of patterns Technical Field The utility model belongs to the technical field of connector molds, and particularly relates to a connector injection mold convenient to demold. Background Injection molding is a manufacturing process widely applied to plastic product production, and a product with a required shape is obtained by injecting molten plastic material into a mold cavity and cooling and solidifying the molten plastic material. In the prior art, a connector injection mold is assembled and locked, injection molding materials are added into the mold, the fluidity of the injection molding materials in the mold is utilized, the temperature is reduced and cooled, a connector model is formed, and then the connector is taken out. In the prior art, after the connector is injection molded, the upper die is difficult to separate from the lower die due to internal pressure, so that the die is difficult to separate, and extra power is needed to separate the upper die from the lower die during demolding, therefore, the connector injection mold convenient for demolding is provided for the problems. Disclosure of utility model In order to overcome the defects in the prior art and solve at least one technical problem in the background art, the utility model provides a connector injection mold convenient to demold. The technical scheme includes that the connector injection mold convenient to demolding comprises a lower mold, a plurality of guide holes are formed in the top of the lower mold, a plurality of positioning pins are fixedly connected to the top of the lower mold, a mold core is fixedly connected to the top of the lower mold, a plurality of guide rods are slidably connected to the side walls of the guide holes, an upper mold is fixedly connected to the top of the guide rods, a plurality of positioning holes are formed in the bottom of the upper mold, the positioning holes correspond to the positioning pins, a cavity is formed in the bottom of the upper mold, an injection molding opening is formed in the top of the cavity, a plurality of first grooves are formed in the top of the lower mold, air cylinders are fixedly connected to the inner side walls of the bottoms of the first grooves, a plurality of air rods are arranged in the tops of the air cylinders, and guide plates are fixedly connected to the tops of the air rods.
