Multi-segment slurry downward suction automatic molding machine for molded products and manufacturing method

Abstract

The invention relates to a multi-segment slurry downward suction automatic molding machine for molded products and a manufacturing method for manufacturing the molded products. The manufacturing method mainly comprises the steps that a first lower slurry suction die and a second lower slurry suction die enter different slurry boxes respectively, meanwhile a first billet layer and a second billet layer are formed when slurry suction is completed, then a transfer die sequentially drives the dies to be subjected to extrusion molding and die combination, so that the first billet layer and the second billet layer are combined and become a thick billet product with double thickness, and the molded products are formed after die combination and hot pressing formation of upper and lower dies. The manufacturing method has the practical advantages that the manufacturing speed is increased, the thickness of the molded products is increased, the shock absorption space of the molded products is enlarged, the buffer and shock absorption effect is improved, the molded products with inner and outer different thickness and/or inner and outer different colors and/or inner and outer different use characteristics can be manufactured and formed, and the surfaces of the mold products are excellent surfaces.

Description

technical field [0001] The invention relates to a molded product multi-stage suction automatic molding machine and a manufacturing method for manufacturing molded products, especially a method that can speed up the manufacturing speed, increase the thickness of the molded product and the shock-absorbing space, so as to increase the buffering and shock-absorbing effect , and can manufacture molded products with different hardness inside and outside and / or different colors inside and outside and / or different use characteristics inside and outside, and the molded products have excellent surfaces. Background technique [0002] Plastic products made of plastic materials are easy to release toxins and cause serious pollution to the environment. They are difficult to recycle and reuse, or are difficult to recycle and decompose, and the cost of recycling is huge, which has caused serious damage to global environmental protection for many years. In today's era of high awareness of en...

AI Technical Summary

Problems solved by technology

[0006] 1. Traditionally, when manufacturing molded products, the adsorption action on the blank layer can only be carried out on one side (the side attached to the mold surface), so the overall dehumidification rate of the blank layer is slow and inconsistent, which in turn affects the manufacturing speed. lead to slow manufacturing

[0007] 2. When traditionally manufacturing molded products, the slurry suction mold can only cover the mold surface with a single layer of blank material layer at one time. The blank material layer cannot be stacked in multiple layers, so the thickness cannot be increased, resulting in poor shock absorption effect. Generally, only It is suitable for small products with smooth appearance and no need to be too thick (such as bowls, plates, cup lids, etc.). effective packaging materials), traditional manufacturing methods are still difficult to achieve

[0008] 3. In the traditional manufacturing of molded products, the suction mold can only cover the mold surface with a single layer of blank material layer at one time, and the blank material layer cannot be stacked in multiple layers, so it is impossible to manufacture different hardness and / or different colors inside and outside. and / or molded products with different usage characteristics inside and outside

[0009] 4. There are non-advantages on the surface, resulting in a low sense of value

It is known that there are obviously two surfaces on one side of the molded product: one side is a good side and the other side is a non-high side. It is suitable for packaging products with low value (such as packaging eggs). When using high-performance products (such as mobile phones), there will be "non-advanced surfaces" in the packaging materials of molded products, resulting in poor visual perception and lowering the value of the overall product

[0010] Because conventional molded products are slow in manufacturing speed, hard to increase in thickness, and have a non-advantageous surface, the promotion of the use of molded products is greatly restricted, and they cannot be directly used for packaging high-value products.
