Rubber mold design basics:
First, the classification of the rubber mold
Rubber mould according to the mould structure and products divided into: production process and forming mold, die-casting molding mold, injection molding, extrusion molding mold four commonly used mold, as well as some special rubber mold, special rubber products, such as inflatable mold, rubber mold, etc.
1. Pressure molding mould
Also known as the common molding. Mixing, it is processed into a certain shape and weigh the semi-finished rubber directly into the mould, and then into pressure, heating plate vulcanizing machine. Rubber vulcanization molding under pressure, heating effect.
Features: mould has simple structure, strong commonality and wide use of surface, easy to operate, it occupies a larger proportion in rubber moulded products.
2. Die casting molding
Is also called the mold or mold and extruded method. It is to mix, simple shapes, limited must be refined rubber or plastic piece of semi-finished products into die mold cavity, through die casting pressure squeeze the rubber plug, and makes the rubber vulcanization shape through pouring system into the mold cavity.
Features: more complicated than the common molding, suitable for ordinary moulding production can't suppress or narrowly pressed thin, long flexible products, as well as complicated shape, difficult to feed rubber products. Using this kind of mold production products good compactness, the quality is superior.
3. Injection molding mould
It is pre heating into plastic state of the gating system of injection mould rubber injection mold vulcanization.
Features: complex structure, is applicable to large and thick wall, thin, shape complex products. High efficiency, stable quality, can realize automatic production.
4. Extrusion mould for
Through the nose of the molding made into all kinds of cross section shape of the rubber profile semi-finished products, to achieve the objective of the preliminary model, and then after cooling to finalize the design to the vulcanizing tank for sulfide or used as the preform molding method need semi-finished rubber.
Features: high efficiency, stable quality, can realize automatic production.
