1. Attention should be paid to rubber mold design

(1) Collect necessary data, including product drawings, samples, design specifications and reference drawings.

(2) Understand whether the production property of the parts is trial production or mass production, so as to determine the structural properties of the mold.

(3) Whether the shape characteristics, size (minimum hole margin, hole diameter, material thickness, maximum shape), accuracy requirements and material properties of the part meet the requirements of stamping process are analyzed.

(4) Determine the reasonable stamping process plan.

(5) Determine the mold structure.

2. Rubber mold is the mold that natural rubber or synthetic rubber is made into rubber molding parts. Also known as rubber mold, rubber pressure mold, rubber vulcanization mold. Metal model used for pressing rubber products. Generally, steel is made by mechanical processing according to the drawing requirements, and heat treated to improve its hardness and wear resistance. Mold cavity and product structure are the same, cavity size must consider different rubber shrinkage, on the basis of product size to enlarge or reduce, in order to get the appropriate product size.

3. According to the different mold structure and product production process, rubber mold can be divided into four common molds: pressing mold, die casting mold, injection molding mold, extrusion molding mold, and some special rubber mold for producing special rubber products, such as inflatable mold, dipping mold, etc.
