Embodiment approach

[0041] As an embodiment of the present invention, a rotating tube 452 is installed in the inner tube 451; the rotating tube 452 and the inner tube 451 can rotate mutually; the rotating tube 452 and the inner tube 451 Displacement cannot occur in the length direction; the side wall of the rotating tube 452 is provided with jet holes along the tangential direction;

[0042]When working, after the blowing pipe 45 is inserted into the mold 3, the controller controls the start of the cylinder 2 41 to insert the inner pipe 451 into the middle of the parison. The gas enters into the inside of the parison through the air injection holes on the rotating tube 452. Since the air injection holes are distributed along the tangential direction, when the air injection holes are spraying, the rotating tube 452 is subjected to the reaction force in the tangential direction, so that the rotating tube 452 rotates, and the gas entering the parison The high-pressure gas in the parison evenly acts ...

Abstract

The invention belongs to the technical field of blow molding, and particularly relates to a blow molding process for children's slide components. The blow molding process for the children's slide components comprises the following steps of S1, uniformly mixing 70 percent by mass of polyethylene, 20 percent by mass of carbon fiber reinforced polypropylene and 10 percent by mass of additive to obtain a preparation raw material of a slide component, wherein the additives comprise an anti-ultraviolet stabilizer, an anti-static agent and an anti-aging agent; S2, heating the raw material obtained inthe step S1 to a molten state, and then extruding the raw material through an extruder to obtain a parison; S3, putting the parison obtained in the step S2 into a forming device, introducing compressed air, blowing up the parison, and obtaining a formed slide component; S4, taking out the formed slide component obtained in the step S3, cutting off tailings, deflashing, then conducting polishing treatment, removing burrs on the surface of the slide component, and obtaining a finished slide component. According to the blow molding process for the children's slide components, a preparation method is simple, and the prepared slide component is high in strength, good in mechanical performance, not prone to cracking and long in service life.

Description

technical field [0001] The invention belongs to the technical field of blow molding, in particular to a blow molding process for children's slide parts. Background technique [0002] Blow molding mainly refers to hollow blow molding (also known as blow molding). It is a method of forming a hollow product from a hot-melt parison closed in a mold by means of gas pressure. It is a fast-growing plastic molding method. The mold used for blow molding only has a female mold (also called a concave mold). Compared with injection molding, the equipment cost is lower, the adaptability is stronger, the plasticity is good, and it can form complex undulating curves (or shaped products). At the same time, when the existing blow molding device is producing plastic barrels, it mainly stretches into the inside of the parison through the blowing pipe to blow air, so that the parison is subjected to inflation, extruded on the inside of the mold, and then cooled and formed. In the production de...
