Abstract
The invention relates to a stacking mould hot runner system. The stacking mould hot runner system comprises a hot runner rear plate, a diversion plate and a hot runner front plate; a needle valve-typesingle nozzle is arranged in the diversion plate; the needle valve-type single nozzle comprises a guide sleeve arranged on the diversion plate, a valve needle A which is coaxially inserted in the guide sleeve and a heating sleeve pipe A which is arranged in the hot runner front plate; an injection nozzle is arranged in the tip end of the heating sleeve pipe A; the valve needle A is coaxially inserted in the heating sleeve pipe A, and a flow guiding passage is formed between the outer peripheral surface of the valve needle A and the inner side wall of the heating sleeve pipe A; the tip end ofthe valve needle A can be inserted in the injection nozzle to seal the injection nozzle; a part, which is located at the tail end of the valve needle A, in the guide sleeve is provided with a cylindrical cavity A; a spring A is arranged in the cavity A; and the valve needle A is in axial slidable match with the guide sleeve. By adopting the stacking mould hot runner system, a hydraulic or pneumatic structure for driving the valve needle to move is omitted, so that manufacturing cost is greatly lowered.
Description
technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a hot runner system for stacked moulds. Background technique [0002] The laminated injection mold is a new type of injection mold with high efficiency, quickness and energy saving, and it has been gradually promoted and used in our country. Stacked injection molds are most suitable for forming large flat parts, shallow cavity shell parts, small multi-cavity thin-walled parts and parts that require mass production. Different from conventional molds, the cavities of laminated injection molds are distributed on two or more parting surfaces in an overlapping arrangement. Compared with conventional molds, the clamping force of laminated injection molds is only increased by 5% to 15%, but the output can be increased by 90% to 95%, which greatly improves equipment utilization and productivity, and greatly reduces production. cost. According to the traditional laminated mo...
