Mold for integrally forming assembled product and injection molding machine

Abstract

The invention discloses a mold for integrally forming an assembled product and an injection molding machine. The mold comprises a wall mold plate, a rear mold plate and a hot runner assembly, a mold cavity used for product forming is formed between the front mold plate and the rear mold plate, the mold cavity comprises a first forming cavity, a second forming cavity and a communicating cavity located between the first forming cavity and the second forming cavity, the first forming cavity and the second forming cavity communicate with each other through the communicating cavity, and the ejection end of the injection nozzle of the hot runner assembly is arranged close to the communicating position of the first forming cavity and the second forming cavity, so that high-temperature melt glue can flow and diffuse towards the first forming cavity and the second forming cavity at the communicating cavity, the flowing path of melt glue can be relatively reduced, and the risk that the melt glue becomes a cold material because the whole mold cavity is not filled with the melt glue is reduced. In addition, two parts can be simultaneously formed on one mold, the cost is saved, and the productivity is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold and an injection molding machine for integral molding of bottled products. Background technique [0002] At present, taking the lower trim of the automobile door panel as an example, the lower trim of the automobile door panel includes two parts assembled and assembled. For the two parts, two sets of molds are generally used for production, occupying two injection molding machines, which relatively increases the production cost. [0003] Moreover, in the prior art, there is a mold capable of molding the above two parts in a set of molds, and the mold is molded by injecting glue on the side of the mould, which is acceptable for smaller plastic products, but for larger plastic products Products, by injecting glue on the side of the mold, it is easy to cause the plastic to become a cold material before the entire cavity is filled when the plastic is formed in the cavity of the ...

[0002] At present, taking the lower trim of the car door panel as an example, the lower trim of the car door panel includes two parts assembled and assembled. The two parts are generally produced by two sets of molds, occupying two injection molding machines, which relatively increases the production cost.

[0003] Moreover, in the prior art, there is a mold capable of molding the above two parts in a set of molds, and the mold is molded by injecting glue on the side of the mould, which is acceptable for smaller plastic products, but for larger plastic products Products, by injecting glue on the side of the mold, it is easy to cause the plastic to become a cold material before the entire cavity is filled when the plastic is formed in the cavity of the mold, and it is easy to produce material flowers or flow lines on the surface of the plastic product
