Rubber molding mold types and characteristics

The following is a table of several common rubber molding mold types and their characteristics:

What materials are used for rubber molding molds?

Common rubber molding mold materials include metal, silicone, and polyurethane. Metal molds are usually made of steel, which is suitable for mass production due to its high hardness and wear resistance. Silicone molds have good flexibility and high temperature resistance, and are suitable for manufacturing rubber products with complex shapes. Polyurethane mold combines the characteristics of metal mold and silicone mold, and has high wear resistance and flexibility.

Rubber molding mold manufacturing process

Mold design: According to product requirements and specifications, carry out three-dimensional design of the mold. Factors such as product shape, size, and material fluidity are considered during the design process to ensure that the mold can meet the expected molding effect and product quality requirements.

Material selection: According to the requirements of the product and the mold, select the appropriate mold material. Common mold materials include metal (such as aluminum alloy, steel), silicone, polyurethane, etc. Material selection should take into account the wear resistance, high temperature resistance, dimensional stability and other factors of the mold.

Mold processing: according to the mold design, use CNC machine tools, electric discharge machining and other processes to process the mold materials. The machining process includes milling, turning, drilling, wire cutting, etc. to obtain the required mold shape and size. During the processing, the precision and surface quality of the mold need to be guaranteed.

Mold assembly: Assemble the processed mold parts, including mold cavity, mold core, positioning pin, guide column, etc. Ensure that the various parts of the mold work in harmony for smooth molding of rubber products.

Mold debugging: Debug the assembled mold, adjust the opening and closing, pressure, temperature and other parameters of the mold through mold testing and adjustment to obtain the best molding effect. During the mold debugging process, multiple trial molds and fine-tuning may be required until the product requirements are met.

Production verification: After the mold debugging is passed, the production verification will be carried out, and a batch of samples will be produced for inspection and testing. The verification results are used to confirm the stability of the mold and the consistency of product quality, and make necessary adjustments and improvements.

How to maintain the rubber molding mold?

Rubber molding molds need regular maintenance and maintenance during use to prolong their service life. Maintenance work includes cleaning the mold surface, repairing mold damage, applying mold surface lubricant, etc. In addition, the correct use of molds and the avoidance of excessive pressure and temperature can also reduce the wear and damage of molds.

Innovations in Rubber Molding Molds

With the development of science and technology, rubber molding molds are also constantly innovating. The application of some new mold materials, such as ceramic molds and composite molds, has better wear resistance and thermal conductivity, which can improve production efficiency. In addition, the application of 3D printing technology also provides new possibilities for the manufacture of rubber molding molds.

The production process of rubber products?

1. Preparation of rubber raw materials

First, the raw material for rubber is prepared. Usually rubber latex, rubber granules or rubber blocks are used as raw materials. According to the product requirements, the rubber raw materials are weighed and mixed, and an appropriate amount of auxiliary materials such as fillers, plasticizers and vulcanizing agents are added.

2. Rubber mixing

Send the mixed rubber raw materials into the rubber mixer for mixing. During the mixing process, the filler in the rubber raw material is uniformly dispersed through the action of mechanical shear and heat energy, and the elasticity and plasticity of the rubber are enhanced.

3. Rubber molding

Send the mixed rubber material into the molding machine for molding. Common molding methods include compression molding, injection molding, and extrusion molding. Compression molding is suitable for making rubber products of smaller dimensions, injection molding is suitable for complex shaped products, and extrusion molding is suitable for continuous length products.

4. Rubber vulcanization

The molded rubber products need to be vulcanized to improve their wear resistance and strength. Rubber products are placed in a vulcanization furnace, and the rubber is cross-linked by heating to form a final product with better strength and elasticity. The vulcanization time and temperature depend on the type of rubber and product requirements.

5. Trimming and inspection

Vulcanized rubber products need to be trimmed and inspected. Trimming refers to modifying the appearance of the product according to product requirements, such as removing burrs and trimming edges. Inspection is the quality inspection of products, including inspection of dimensions, appearance and performance.

6. Packaging and storage

Qualified rubber products are packaged and marked after inspection. According to the characteristics and requirements of the product, select the appropriate packaging material, and carry out appropriate labeling and packaging. Then store the packaged products in a dry, ventilated warehouse, away from moisture and direct sunlight.

The above is the general production process of rubber products. Different types of rubber products may have some differences, but the overall process is similar. In the whole production process, strict control of the quality of raw materials, parameters of processing technology, and quality inspection and control are the keys to ensure the quality and performance of rubber products.
