Production equipment and production process of a low-cost large-scale plastic part

Abstract

The invention relates to a production equipment and production process of low-cost large-scale plastic parts. The feeding and extrusion are divided into three steps. The machine is aligned with the mold of the next station, and the feeding and extrusion steps are repeated according to the set feeding time and sequence. In the production process of the present invention, the large-scale mold is not moved, but the extruder is moved by moving devices such as guide rails, thereby realizing the production of large-scale production parts at different stations.

Description

technical field [0001] The invention relates to a chemical production equipment and process, in particular to a production equipment and a production process of low-cost large-scale plastic parts. Background technique [0002] In chemical production, especially in the production of large plastic parts, such as plastic parts weighing more than 10 kg, the most common method is to use large and super large injection machines and large molds. Large and ultra-large injection machines are expensive, often costing millions of dollars, and small enterprises have limited purchasing power and production is hindered. In addition, large injection machines and large molds are large in size and weight, and are not easy to move during production, and they are rarely moved in actual production, so they cannot be used conveniently and flexibly according to needs; moreover, the mold wall thickness of large plastic parts is relatively large. The cooling time is long. In order to completely co...

Large and ultra-large injection machines are expensive, often costing millions of dollars, and small companies have limited purchasing power, hindering production

In addition, large injection machines and large molds are large in size and weight, and are not easy to move during production, and they are rarely moved in actual production, so they cannot be used conveniently and flexibly according to needs; moreover, the mold wall thickness of large plastic parts is relatively large. The cooling time is long. In order to completely cool the large plastic parts, the large injection machine often has to work and stop working once the time is up. After the large plastic parts are completely cooled, they will continue to work. This will cause a waste of the injection molding machine, and some plastic parts Instability, when the injection molding machine is not working, if it is left for too long, the plastic will easily decompose in the barrel, which will easily lead to unstable performance of the final produced plastic parts
