Problems solved by technology

The existing hot nozzles are all S136 steel hot nozzles. This kind of hot nozzle is difficult to process hard and dissipates heat quickly. In order to keep the plastic raw materials in the hot nozzle in a molten state, the current practice is to heat There is a heating ring on the mouth, so that the plastic material must be sealed under the heating ring, that is, the closed ring must be closely matched with the cavity
In order to meet the above requirements, technicians need to improve the processing accuracy of the cavity, otherwise, there will be glue overflow at the contact part of the hot nozzle and the cavity, and then the plastic raw material will be immersed in the heating ring, so that the heating ring will be short-circuited and the entire heat sink will be burned. mouth, eventually affecting the normal work of the hot nozzle
If you choose to carry out maintenance, not only need to replace the new heating coil, invest manpower and material resources, but also greatly reduce production efficiency, thereby increasing the investment of enterprise costs

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as Figure 1 to Figure 3 As shown, a hot runner hot nozzle, the hot nozzle 1 is a copper hot nozzle, it can be a copper hot nozzle, beryllium copper hot nozzle, bronze hot nozzle and other copper hot nozzles, and this solution uses red copper hot mouth.

[0016] The hot nozzle 1 has an integrated structure and is divided into two parts: the installation end 11 and the glue inlet end 12 . The installation end 11 is a disc shape, which is used for connecting with the heating plate 3 to absorb heat in a large area. The glue inlet 12 is in the shape of a square prism, and concave surfaces 121 are provided on the four sides and the top surface of the glue inlet 12, and a concave platform 123 is provided between adjacent two sides and near the installation end 11. , a corner 122 is formed at a position away from the installat...

Abstract

The invention provides a hot nozzle of a hot runner. The hot nozzle is characterized of being a copper hot nozzle, the copper hot nozzle is provided with a mounting end and a rubber inlet end; the rubber inlet tend is in a regular quadrangular shape, and concave surfaces are arranged on the four side surfaces and the top surface of the rubber inlet end; a concave platform is formed in a part between the adjacent two side surfaces and close to the mounting end, a corn is arranged at a part, far away the mounting end, and rubber holes communicated with a hot nozzle main rubber are formed in the four corners. When the hot nozzle of the hot runner is applied to a hot runner technique, the hot nozzle does not need to be sleeved by a heating ring, so that a problem that the heating ring burns the hot nozzle due to rubber leakage is avoided, the service life of the hot nozzle is prolonged, and the production efficiency of the corporation is improved; and the hot nozzle has the advantages of easiness in processing, low cost and the like.

Description

technical field [0001] The invention relates to the field of hot runner pouring, in particular to a hot runner nozzle. Background technique [0002] The hot runner means that the plastic raw material sent from the nozzle of the injection machine to the gate is always in a molten state. It does not need to be solidified and taken out as waste every time the mold is opened. The melt remaining in the gating system can be injected into the mold when it is injected again. cavity. During the entire production process, when the plastic raw material passes through the nozzle, it must first enter the heating plate for insulation and diversion before injecting the plastic through the hot nozzle. The purpose is that the plastic raw material must be in a molten state before entering the cavity. The existing hot nozzles are all S136 steel hot nozzles. This kind of hot nozzle is difficult to process hard and dissipates heat quickly. In order to keep the plastic raw materials in the hot n...
