Demand For Automotive Mould Is Increasing
-
In the development of the automobile industry, the demand for Automotive mould has increased. Plastic products have greatly promoted the development and construction of the automobile industry and the quality of automobile moulds has been determined. At the same time, automotive products are constantly being updated. Only by mastering the key to the production of plastic parts molds, the new molds can meet the needs of the development of the automotive industry. Automotive lamp molds occupy a large market share in automotive molds. Car lights are the collective name for all car lighting systems. Several important parts are transparent parts, electroplated parts, etc., so the design and manufacturing requirements for automobile lamp molds are very high. The main components of the lamp are: lens, decorative frame, lampshade, reflector, etc. The lens is the outermost transparent part of the car light. Generally, car lights are white and transparent, with A-level curved surfaces and super hard coatings, which are the most important car parts.
For automobile lamp mold, it is divided into two parts: fixed mold and mobile mold. The fixed mold temperature control system includes 4 cooling water channels (4 in and 4 out). The dynamic mold temperature control system consists of 5 cooling water channels (5 in and 5 out). In order to reduce the molding cycle and improve the quality of the plastic lamp, the location of the water channel must be reasonably designed so that the temperature around the mold cavity can be roughly balanced.
To this end, the cooling channel uses a combination of "vertical water pipe + inclined water pipe + diaphragm well". This cooling system is best to use vertical water pipes, then inclined water pipes, and must use diaphragm water wells. As a last resort, the cooling water channels of this combined form are evenly arranged and close to the cavity, and the molding cycle is successfully controlled within 35 seconds, which is suitable for the molding of large quantities and high-precision plastic lamps.
The difference from Flower Pot Mould is that the automobile lamp mold adopts a common gating system and is fed by a fan gate tower. Compared with the previously used hot runner gating system, not only the cost is greatly reduced, but the light transmittance of the lamp is better.
