Abstract

The invention discloses a separation system of a runner condensed material in a die. The separation system comprises a feed inlet, wherein a screw rod is arranged below the feed inlet; the screw rod is connected with a fixed die; a main runner and a sub runner are arranged in the fixed die; a moving die is matched with the fixed die; a concave air flue is arranged at the end part of the moving die; one end of the air flue is connected with air pumps, and the other end of the air flue is connected with cutting knives; each cutting knife comprises a cutter mounting seat and a cutter; each cutter is formed through connecting a cutter head and a cutter body; and a rotatable limiting shaft is arranged on each cutter head. The separation system has the benefits that the runner condensed material can be automatically separated from a finished product and the die during production of the plastic die, the production efficiency is improved while the quality of the produced product is guaranteed, the runner condensed material can be used for feeding again after being minced, and the resource is saved.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to a separation system for condensate in a flow channel in a mould. Background technique [0002] With the rapid development of the plastics industry, the application of plastic molds is becoming more and more extensive, but in actual production, the product and the flow channel aggregate usually need to be separated manually. At present, there are two common separation methods: [0003] The first is the ejection mechanism of the gating system condensate. Among all kinds of gates, except point gates and latent gates, the gating system condensate and plastic parts are connected together and separated from the mold when demolding. Then it is separated by hand, which causes a large weld mark at the gate of the product, poor product quality, unsightly surface, and even damages the product when the gate is manually removed or the outer surface of the product is removed when the pouring ...
