AI Technical Summary
During the non-continuous injection production process of existing injection molding machines, the temperature drop at the casting port often causes gas marks or wavy textures to appear at the injection port, which cannot meet customer requirements and waste production costs.
A casting port and cavity connection structure is designed. By setting a flow channel and a transition block on the cavity template, the casting port of the flow channel is connected with a transition block, so that the melt is sprayed into the cavity through the transition block.
Through the connection between the runner and the cavity, the melt is uniformly sprayed into the cavity after the interval time, avoiding the occurrence of air marks or wave textures and improving product quality.
