Energy-saving and material-saving special-shaped gate runner molding parts

Abstract

The invention relates to an energy-saving and material-saving special-shaped sprue runner forming part used in the injection molding process of LED brackets. The forming part is a plate-shaped whole, and the two side plates of the forming part are respectively the front plate surface and the back plate surface, the front plate surface is provided with a flow channel, and the back plate surface is provided with a molding cavity, and the A special-shaped gate passing through the plate body of the molding part and connecting the two is provided between the runner of the mold and the molding cavity. The runner and the molding part in the present invention constitute a plate-shaped whole, and the PDA resin for injection molding can be directly injected into the flow on the back plate surface of the energy-saving and material-saving special-shaped gate runner molding part from the material pot and the nozzle mouth. and then injected into the molding cavity of the LED bracket product through the special-shaped gate that penetrates the molded component plate. Due to the shortened injection molding path and stable filling of the special-shaped gate structure, the yield of the injection molded LED bracket is high, and the utilization rate of the mold and resin is high. Energy saving and material saving, the product cost of unit LED bracket is greatly saved.

Description

technical field [0001] The invention relates to an energy-saving and material-saving special-shaped sprue runner forming part used in the injection molding process of LED brackets. Background technique [0002] At present, in the LED bracket injection molding process, the structural design of the LED lead frame and the design of the LED bracket injection mold have gradually become bottlenecks, and are increasingly unsuitable for LED chip design, LED supporting product design, and energy-saving and low-carbon industries advocated by the state. Explosion of ideas. Existing LED bracket injection molds have a single design structure for the glue inlet flow channel, relying on ordinary nozzles and resin flow channels to feed glue, and the efficiency of each glue injection is very low, the filling is unstable, and the shape and structure of the gate on the mold each time are rough and difficult for injection molding. The yield rate of LED brackets is low, the utilization rate of ...

Problems solved by technology

Existing LED bracket injection molds have a single design structure for the glue inlet flow channel, relying on ordinary nozzles and resin flow channels to feed glue, and the efficiency of each glue injection is very low, the filling is unstable, and the shape and structure of the gate on the mold each time are rough and difficult for injection molding. The yield rate of LED brackets is low, the utilization rate of molds and resins is low, and the product cost per unit of LED brackets is high. The traditional resin flow method and gate design can no longer meet the production upgrade, technology improvement and high-speed development of the LED industry. Therefore, customers urgently need new products. The emergence of unique runners and gate molding parts to solve long-term problems, and improve the production efficiency of the LED bracket injection molding process, enhance product competitiveness and reduce costs
