Problems solved by technology

[0003] However, there are some problems in the existing ones. Most of the existing molding injection molding operations require injection molding and mold taking; and then prepare for the next injection molding; but most of the existing molding injection molding adopts a separate method, separating the injection molding part and the mold clamping part. , to achieve independent operation; in the actual production process, the increase in the path of the injection molding part and the mold clamping part will not only accelerate the cooling of the liquid; , so in the case of small parts, the uniform distribution of liquid in each cavity cannot be guaranteed; in addition, traditional ejection needs to be done on the same side, thus limiting the operating range

Abstract

The invention discloses a forming injection mold and an injection molding method thereof. The forming injection mold comprises an injection molding plate, an upper mold arranged below the injection molding plate, a lower mold arranged below the upper mold, a bottom plate arranged on the lower mold and a driving assembly arranged at the cooperation position of the injection molding plate and the upper mold; then the injection molding plate is placed on the upper mold; then an injection molding portion and a mold closing portion are combined, and blockage caused by long-time retention of injection molding liquid to a nozzle opening is reduced; meanwhile, a vertical forming injection molding processing mode is adopted so that molds with different specifications can receive uniform injection molding liquid; and injection molding liquid in a mold groove is prevented from being distributed unevenly during transverse machining, the forming mold is subjected to automatic demolding through springs while the injection molding plate is jacked up by limiting pins, in addition, the material pushing speed and distance of the mold after demolding are set according to the driving assembly, and damage to different injection molding materials is avoided.

Description

technical field [0001] The invention relates to an injection molding device, in particular to a molding injection mold and an injection molding method thereof. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding; at a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and after cooling and solidification, a molded product is obtained. . [0003] However, there are some problems in the existing ones. Most of the existing molding injection molding operations require injection molding and mold taking; and then prepare for the next injection molding; but most of the existing molding injection molding adopts a separate method, separating the injection molding part and the mold clamping part. , to achieve independent operation; in the actual production process, the increase in the path of the injection molding part and the mo...
