LED bracket injection molding mold and method

Abstract

The invention discloses an LED (Light Emitting Diode) support injection moulding die and a method. The LED support injection moulding die comprises a lower fixing plate, die feet, a bearing plate, a male template, a female template and an upper fixing plate which are sequentially arranged in an overlapping manner from bottom to top, wherein a runner plate is arranged in the female template, is 7mm thick, and is provided with a main runner on the surface in a concave way, and the width, the depth and the bilateral slant angles of the main runner are respectively 1.8mm, 1.5mm and 20 DEG. Through arranging various specific runners on the runner plate, molten plastic can flow in the runners more smoothly, the plastic feeding efficiency is higher, the filling is more stable, the yield of the LED supports produced by injection moulding is higher, and the quality is better, moreover, through arranging the runners, the travel of each runner is effectively shortened, and the generation of excess materials are greatly reduced, so that the material utilization is greatly improved, the unit cost of the LED support product is reduced, the productive benefit of LED support injection process is improved, the product competitiveness is enhanced, the cost is reduced, and the production upgrade, technical promotion and high-speed development of LED industry can be satisfied.

Description

technical field [0001] The invention relates to the technology in the field of LED brackets, in particular to an injection molding mold and method for LED brackets. Background technique [0002] LED (light-emitting diode) is a new type of semiconductor light-emitting device, which has the advantages of small size, large scattering angle, good uniformity of light emission, high reliability, low power consumption, fast response speed, etc., and the light-emitting colors include various colors including white light. , so it is widely used in various electronic products. [0003] 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 si...
