Description

Back mold, mold, molding device and injection molding production line

Technical Field

The utility model relates to the technical field of molds, and in particular to a rear mold, a mold, a molding device and an injection molding production line.

Background Art

The rear mold refers to the rear part of the mold, that is, the part opposite to the front mold. Its main functions include: ① forming the external shape and size of the injection molded part to ensure the quality and precision of the injection molded part. ② determining the closing height of the mold and the injection process parameters. ③ providing a channel for the injection molded part to be demolded and ejected. ④ bearing the injection pressure and the impact of the injection machine to ensure the stability and reliability of the mold. ⑤ facilitating the installation and commissioning of the mold.

At present, the existing rear mold structure has a similar ratio between the lower and upper parts, which makes it easy to deflect during the injection molding process. The deflection will cause the peripheral thickness of the output product to be uneven, resulting in defective products, causing material waste and increased costs.

The mold body 1 includes a carrier 11 and a molding member 12, the molding member 12 is arranged on the carrier 11, and the molding member 12 protrudes from the upper part of the carrier 11, and the pusher body 2 is arranged around the molding member. The carrier has a receiving groove 111, the molding member 12 and the pusher body 2 are both located in the receiving groove 111, the pusher body 2 is arranged on both sides of the molding member 12, and the pusher body 2 is slidably arranged in the receiving groove 111, and when the product is formed, the product is pushed out by the pusher body 2. Furthermore, a limiting step 112 is provided on the outer surface of the carrier 11, and the setting of the limiting step 112 facilitates the movement of other components to be limited. In this embodiment, there are two limiting steps 112, which are respectively located on opposite sides of the carrier 11. It should also be noted that in order to further improve the fixing effect of the molding 12, the carrier 11 and the molding 12 are an integral molding structure in this embodiment.

In specific application, the pusher body 2 includes a first pusher block 21 and a second pusher block 22.
