Abstract

The invention discloses a full-rubber-leakage-proof hot runner system. The full-rubber-leakage-proof hot runner system is formed by completely and tightly attaching a spraying layer and a feeding layer together, a hot runner formed by corresponding grooves is formed in the contact surface between the spraying layer and the feeding layer, a temperature controller is arranged around the hot runner,a main nozzle is arranged on the spraying layer, one end of the main nozzle is open to the outside, the other end of the main nozzle is connected with the hot runner, the feeding layer is provided with a feeding port, one end of the feeding port is connected with the outside, and the other end of the feeding port is connected with the hot runner. According to the full-rubber-leakage-proof hot runner system, the hot runner formed by the corresponding grooves is formed in the contact surface between the spraying layer and the feeding layer, the main nozzle is formed in the spraying layer, and the feeding port is formed in the feeding layer, so that the whole system has high sealing performance, and the problem of rubber leakage in the prior art is solved.

Description

technical field [0001] The invention relates to the field of mold injection molding, in particular to a full leak-proof glue hot runner system. Background technique [0002] At present, the development direction of hot runner molds is widely used in all walks of life, such as automobiles, cosmetics packaging, household appliances, medical supplies, household appliances, etc. It is a typical modern energy-saving injection molding product, which saves labor, saves cost materials, and improves production capacity. Due to the use of hot runners, the product can be molded directly. [0003] Existing hot runner molds generally have glue leakage. The normal location of glue leakage is usually from the following places: 1. The plane between the injection nozzle and the runner plate; 2. The plane between the runner plate and the hot nozzle; 3. 1. The connection between the hot nozzle and the flange thread; 4. The sealing position of the hot nozzle and the joint of the mold. In orde...
