Embodiment Construction

[0036] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0037] The invention relates to a production process for in-mold forming articles, comprising the following steps:

[0038] ① Mix the raw material particles and foam glue well, and stir evenly, so that each raw material particle is covered with a layer of glue layer; specifically, the minimum requirement for the glue layer is: the surface of the raw material particles must be covered with foam Bubble glue.

[0039] ② Put the raw material particles with a glue layer on the outside into the cavity of the forming mold;

[0040] ③Heat and pressure to make the foaming glue produce foaming and bonding, so that adjacent plastic particles are tightly bonded to each other through the glue layer. Preferably, a flat heat transfer die-casting machine is used to realize heating and pressing, and the heating temperature is...

Abstract

The invention discloses a manufacturing process of intra-mold molding supplies. The manufacturing process comprises the following steps that 1, matching is carried out on raw material particles and foaming glue, and sufficient stirring is conducted, so that the outer surface of each raw material particle is covered with a glue layer; 2, the raw material particles with the outer surfaces provided with the glue layers are put in a cavity of a molding mold; and 3, heating and pressing are conducted, the foaming glue is made to generate foaming bonding, and the adjacent plastic particles are firmly bonded together through the glue layers. Compared with the prior art, material selection is quite rich, and the manufacturing process has the characteristics that the cost is low, products are varied, and the appearance effect is good.

Description

technical field [0001] The invention relates to the field of processing and molding of sporting goods or daily necessities, in particular to a production process of in-mold forming products, which can be protective gear, floor mats, seat cushions, insoles, shoe soles and shoe uppers. Background technique [0002] In-mold molding products generally use processes such as injection molding or heating foaming to form products in the mold that match the shape of the cavity. Injection molding process is a traditional method of producing shapes for industrial products. It is generally divided into rubber injection molding and plastic injection molding. Plastic injection molding is to inject molten plastic into the mold of plastic products under pressure. After cooling and molding, you can get the desired products. kinds of plastic parts. [0003] The heating foaming process refers to the use of raw materials such as plastics, adding catalysts, foam stabilizers, foaming agents and ...
