Forming die of injection molding machine

Abstract

The invention discloses a forming die of an injection molding machine. The forming die comprises a base, mounting holes are formed in the four corners of the base, a lower die is fixedly connected to the upper end of the base, a mounting cavity is formed in the middle of the upper end of the lower die, limiting rods are mounted at the four corners in the mounting cavity, penetrating holes are formed in the four walls in the mounting cavity, and limiting holes are formed in the four corners of the top end wall of the lower die. Fixing bolts are installed on the left side wall and the right side wall of the lower die, air pipes are mounted on the front end wall and the rear end wall of the lower die, fixing rings are mounted at the roots of the two air pipes, an inner die is mounted in the mounting cavity, a plurality of forming cavities are formed in the inner die, and a plurality of air holes are formed in the inner bottom end walls of the multiple forming cavities. A lower die seat is composed of two parts, and the inner die is mounted in the lower die through fixing blots in a pin tensioning mode. When in use, the inner die can be taken out and mounted at will and is convenient to take out, subsequent replacement of dies of different sizes for injection molding is facilitated, the whole lower die does not need to be replaced, convenience and rapidness are achieved, and the practicability of the forming die is improved.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a molding die for an injection molding machine. Background technique [0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The injection molding function The plastic is heated and high pressure is applied to the molten plastic, causing it to shoot out and fill the mold cavity. [0003] In the existing technology, the lower mold of the forming mold of the injection molding machine is generally a whole. When it is processed and used, it is inconvenient to replace the mold. After long-term use, some dust and garbage generated inside are inconvenient to discharge and accumulate inside the mold, resulting in a decrease i...

[0003] In the existing technology, the lower mold of the forming mold of the injection molding machine is generally a whole. When it is processed and used, it is inconvenient to replace the mold. After a long time of use, some dust and garbage generated inside is inconvenient to discharge and accumulate inside the mold, resulting in a decrease in the stability of the mold and affecting the use of the mold
