Embodiment 1

[0026]The present invention is a spoiler high-gloss blow molding process, which includes the following process steps in sequence: raw material drying, feeding, raw material heating, mold opening, screw extrusion, mold closing, air blowing, exhaust, and mold opening; Among them, the mold is heated by steam in the stages of mold opening, screw extrusion and mold closing, and there is also a process step of cooling the mold between the exhaust and mold opening processes. A waterway is set in the mold involved in the mold opening and closing process, and saturated steam is passed into the waterway when the mold steam is heated, and cold water is passed into the waterway when the mold is cooled. In the process step of cooling the mold, after the cooling is completed, the compressed air is passed through the water circuit to blow out the residual moisture. In the raw material drying process, the modified acrylonitrile-butadiene-styrene plastic is added to the dehydrator for drying, ...

Embodiment 2

[0028] The difference from Embodiment 1 is that, as Figure 1 to Figure 8 shown (for illustration purposes, image 3 The fourth cylinder, the fifth cylinder and the sixth cylinder are not shown), in the process step of cooling the mold 5, after the cooling is completed, a process of scraping the residual cooling water in the water channel 1 with the wiper 2 is provided. A ring-shaped or semi-circular wiper blade 2 is arranged at one port of each waterway 1. The wiper blade 2 is made of aluminum alloy or silicon rubber, and a ferromagnetic suction block 3 is fixed inside the wiper blade 2. The ball 4 made of permanent magnet material compatible with the suction block 3 is arranged outside the waterway 1. The mold 5 is made of martensitic or ferritic stainless steel. The waterway 1 set on the mold 5 is U-shaped or L-shaped. 5 is fixedly provided with several air cylinders or hydraulic cylinders, and a push block 7 is fixedly arranged on the piston rod of each air cylinder or hy...

Abstract

The invention discloses a spoiler high-gloss blow molding process, which comprises the following process steps in sequence: raw material drying, feeding, raw material heating, mold opening, screw extrusion, mold closing, air blowing, exhaust, and mold opening ; Among them, the mold is heated by steam in the stages of mold opening, screw extrusion and mold closing, and there is also a process step of cooling the mold between the exhaust and mold opening processes. The invention can realize rapid cooling and rapid heating, can make the extruded material smooth in the mold, can greatly shorten the cooling time of the product, and improve the production efficiency; the finished product has no marks and pits on the surface, and basically does not need to be polished, even if it needs to be polished The time required is also greatly shortened and the grinding efficiency is improved; high-gloss blow molding technology is an advanced production process, which improves the surface of the product, reduces the subsequent processing process, greatly reduces production costs, protects the environment and reduces pollution. .

Description

technical field [0001] The invention relates to a spoiler highlight blow molding process. Background technique [0002] The high-gloss blow molding process can be used in many ways; the traditional method is to use a mold temperature machine to heat the mold. This method has many shortcomings and cannot meet the rapid heating and cooling in high-gloss blow molding. The amplitude is small, and there are many air marks, pits and grooves on the product surface. Due to the high hardness and poor fluidity of the plastic, the surface of the product produced by this process is very rough, which cannot meet the demand, and the mold expands when the temperature rises, and shrinks when the temperature cools down, making the clamping force unstable. [0003] The patent with the publication number CN101791843A: the steam heating system to control the rapid temperature change of the injection mold, through the integration of steam boiler, steam storage and steam controller and other mod...
