Abstract

The invention relates to a three-dimensional inner-mould inlay injection (IML) product heating and punching method. A molding die and a punching die are combined into a heatable combined die. An IML product is formed and punched by one step in a combined die closing process. The combined die comprises an upper die part and a lower die part, wherein the upper die part consists of four guide sleeves, an upper formwork, a punch head fixing plate, a discharging plate and a punch head; a heating rod and a thermoelectric couple are embedded on the side faces of the punch head fixing plate respectively and connected with a control meter through an electric cable respectively; the lower die part consists of a lower formwork, a ball guide sleeve, four guide pillars, two base plates and a concave formwork; and two heating rods and one thermoelectric couple are embedded on the side faces of the punch head fixing plate respectively and connected with the control meter through the electric cable respectively. By the method, the punching qualification rate of the IML product is up to 90 percent; the production time of the product is shortened; and the production efficiency and the quality of the product are improved. The punching method is easy to operate and the product positioning is accurate, so the method meets requirement of large-scale mass production.

Description

technical field [0001] The invention relates to a three-dimensional IML product punching method, in particular to a three-dimensional IML product heating punching method, which is applied to an IML product that needs to be formed and punched at one time. Background technique [0002] Usually, IML products are shaped first and then punched, which will increase a lot of intermediate turnover and operation time, and reduce production efficiency and product quality; while three-dimensional IML products can be combined by heating and punching. For one step, the production time of the product is greatly shortened and the product quality is improved. Therefore, the design and development of the heating punching method for the three-dimensional IML product is necessary. Contents of the invention [0003] The purpose of the present invention is to provide a new punching method for the shortcomings of the punching process of IML products, that is, the problems of many intermediate t...
