BMC reflector mould supplier and manufacturer

BMC car light mould background technology:

BMC material is a thermosetting material, which is mixed with various inert filler materials, multi-fiber reinforcement materials, catalysts, stabilizers and pigments to form a composite material for pressing plastics. The glass fiber accounts for 10-30. %, the fiber length is generally 6 ~ 12mm; in special cases, in order to meet the mechanical properties, the fiber length to 25mm.
BMC materials are light and corrosion resistant. The advantages of good insulation, etc., can process various free-form surfaces with complex shapes, not only meet the requirements of light distribution, but also produce high precision and stability of automobile lamp mirrors. With the advancement of science and technology and the rapid development of industrial molds, the competitiveness of new product development is getting bigger and bigger, and the requirements for new products of automobile lamp reflectors are becoming more and more strict. The molding process of the prior art is time-consuming and labor-intensive. Inefficiency, high scrap rate, product accuracy does not meet the requirements of use.
For example, in the BMC mold development process of the lamp, the position of the BMC glue in the prior art is at the top of the product, and the flow rate of the inlet gate starts to flow to the bottom at the high point during the mold clamping injection, and finally to the high-end molding. Such a flow will be too high pressure, resulting in a large pressure on the mold. When the mold is used in mass production, repeated production will reduce the service life of the mold; it is easy to trap the gas, and the mold is heated when the mold is closed. The mold causes the heat in the mold to be reserved. There is a large amount of trachoma in the molding of the product, and the cost of the product is increased due to the numerous manual manufacturing processes. The precision and safety are far from satisfying the market for the lamp products. Requirements.

BMC lamp mold Technical summary

The utility model discloses a BMC vehicle lamp mould, which comprises an upper web, a fixed template, a cavity, a core, a movable template, a die foot, a thimble plate and a lower web which are arranged from top to bottom in sequence, and the fixed template is fixed. The fixed mold insert has a movable mold insert which is matched with the fixed mold insert to form a split runner, and the fixed template is provided with a main passage running through the fixed mold insert and communicating with the branch passage, and the branch passage is connected with the inlet gate. The inlet gate is connected with the middle of the core, and the bottom end of the ejector plate is provided with an injection molding machine ejector rod passing through the lower web. The fixed template is symmetrically provided with two cavities, and the movable template has two positions corresponding to the two cavities. The core has two split runners connected to the main flow passage. The two split runners communicate with the two cavities through two inlet gates respectively, which reduces the injection pressure of the mold and shortens the filling time, and the heat in the mold can be uniformly diffused. Easy to form, reduce labor costs, improve production quality, easy to operate and fill, while ensuring delivery and quality, and extending mold life.
