Description
Technical Field
The utility model relates to the technical field of hot-press molding equipment, in particular to an ultrathin film heating forming die device and a pneumatic press.
Background
The hot press molding may be divided into vacuum molding and compression molding, and the pressing manner is different. Most of compression molding is to place plastic in a mold, heat and soften the plastic, and then apply pressure to mold the plastic. The pressure source applied in vacuum forming can be single-side vacuum pumping, or one side is vacuum pumping, and the other side is high pressure. Compared with other processing methods, the hot-press forming has the advantages of cheap die, uniform thickness of finished products and the like.
The important characteristics of the hot-press molding material include the following two characteristics:
firstly, plastic memory: the memory of the plastic can make the plastic become rubber-like after being heated, and the plastic is tightly attached to a mould, which is an important characteristic of the material. Due to this characteristic, the poorly formed product can be heated outside the mold to restore it to its original flat plate shape.
Second, heat strength and heat elongation: thermal strength and thermal elongation are two properties associated with plastic memory. The heat strength is the strength left by the plastic after heating. Some plastics lose all their strength and become soft and sticky when heated, but some plastics still have strength rebound when heated. A plastic with high heat strength can be stretched over a mold, but a low heat strength plastic will tear quickly when stretched. Therefore, the material with strong hot strength is the material with high hot tearing strength.
The prior art has the following defects:
1. the mold design is too complex;
2. the manufacturing cost is high;
3. the down force of the motor-driven screw is limited, and larger clamping pressure cannot be provided.
