Turnover double pulp sucking automatic molding machine for molded product and production method of molded product

Abstract

The invention relates to a turnover double pulp sucking automatic molding machine for a molded product and a production method of the molded product. According to the method provided by the invention,upper and lower pulp sucking molds respectively enter a pulp box to suck a pulp at the same time to form an upper blank material layer and a lower blank material layer, cold mold extrusion is quicklycompleted through driving of a turnover mechanism, the upper and lower pulp sucking molds are closed to make the upper and lower blank material layers combined to form a thick blank product with a double thickness, and hot pressure molding is performed through hot press upper and lower molds; the machine provided by the invention has the practical effects of simplifying assembly space, accelerating the production speed, increasing the thickness and shock absorbing space of the molded product, gaining the buffering shock-absorbing effects, and making the surfaces smooth.

Description

technical field [0001] The invention relates to a molded product flip double-suction automatic molding machine and a manufacturing method for manufacturing molded products, especially a method that can simplify assembly space, speed up manufacturing, increase the thickness of molded products and shock-absorbing space, and The invention relates to a double-suction automatic molding machine and a manufacturing method for a molded product which has the effect of gaining cushioning and shock absorption and which makes the surface all smooth. 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 environmental protection, it has become the mainstream of r...

AI Technical Summary

Problems solved by technology

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

[0007] 2. The thickness cannot be increased, resulting in poor shock absorption effect

When traditionally manufacturing 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 the thickness cannot be increased. Generally, it is only suitable for molding with a smooth appearance and no thickness. Small products that are too thick (such as bowls, plates, cup lids, etc.), if you want to manufacture thicker molded products with better shock absorption effects (such as packaging materials with better shock absorption effects), traditional manufacturing methods difficult to achieve

[0008] 3. 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

[0009] 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.
