Problems solved by technology

However, nitrite is a highly toxic substance. During the slush molding operation, the high-temperature nitrite magma pool is open, which is very dangerous to the operators. During these operations of uncured plastic slurry, the nitrite molten slurry is likely to seep into the plastic in the mold, making the product contain a certain amount of nitrite, which poses a potential threat to the health of consumers

Embodiment Construction

[0025] Please refer to FIG. 1 , which is a cross-sectional view of the plastic forming device of the present invention. The plastic forming device includes a box body 1 , an opening 2 and a heating device 3 . The box body 1 is a semi-closed box body, the opening 2 is arranged on the upper part of the box body 1, a semi-closed cavity is formed inside the box body 1, and there is enough space inside to accommodate the heating device 3, molds, etc., and the heating device 3 is placed in the box body 1 side wall.

[0026] In order to make the plastic forming effect better, solidify more uniform, and yield higher, the plastic forming device further includes a baffle 4 arranged between the opening 2 and the heating device 3, and the baffle 4 is a heat insulating material, which can be nitric acid Aluminum fiber cotton, etc. The baffle plate 4 separates the mold placed at the opening 2 from the heating device 3 to reduce or prevent the mold placed at the opening from being subjecte...

Abstract

The invention provides a method for taking shape the plastics, including the following steps: (1)pour the plastics into the molding tool;(2)put the molding tool with the plastics into the device filled with the heat air, let it heat up homogeneous, making the outside layer of the plastic in the molding tool solidify by heat. The invention still provides the a device the used for the implement the of the above- mentioned the taking shape plastics, the it includes the body the of the box, the openings and the fever device, the body the is the half closed body, the openings the is in the body' the s upper part, the inner the part of the body the forms the half closed room, the fever equipment places in the sideboard of the body. The method that taking shape the plastics is safe without poisonous, the operation is simple, the finished product rate is high and effective.

Description

technical field [0001] The invention relates to a plastic forming method and its device, in particular, the invention relates to a plastic forming method and its device in the slush molding process of thermosetting plastics. Background technique [0002] Plastic is a material with high molecular weight synthetic resin as the main component, which can be molded into a certain shape under certain conditions (such as temperature, pressure, etc.) and remains unchanged at room temperature. [0003] According to the performance of the surface after heating, plastics can be divided into two categories: thermosetting plastics and thermoplastics. The characteristic of the former is that at a certain temperature, after a certain period of heating, pressurization or adding a hardener, a chemical reaction occurs and hardens. The chemical structure of the hardened plastic changes, the texture is hard, insoluble in solvents, and it will no longer soften when heated. If the temperature is...
