Hot-runner injection mould device for inclined pouring gate

Abstract

The invention discloses a hot-runner injection mould device for an inclined pouring gate. The hot-runner injection mould device for the inclined pouring gate structurally comprises a hot runner, a valve needle, a nozzle, a fixing bolt, pistons, an injection mould main body and a fixed mould, wherein the hot runner is arranged above the injection mould main body and is in through connection; the valve needle is connected to the right upper side of the injection mould main body; one end of the bottom of the valve needle is inserted into the middle part of the nozzle; the valve needle and the nozzle are in buckled connection through a clamping buckle; the fixing bolt is in screwed connection with the injection mould main body through a threaded connecting hole; two pistons are provided, and the pistons are arranged on the two sides of the upper part of the injection mould main body respectively; the injection mould main body is arranged inside the fixed mould. Through arrangement of an automatic cooling mechanism, when the temperature during using of the hot-runner injection mould device for the inclined pouring gate is too high, the injection mould can be automatically cooled, so that equipment protection is facilitated and the improvement on the situation of too high temperature of a workshop is facilitated; in addition, through adoption of a water circulating cooling method, high environment friendliness is achieved and no waste is produced.

Description

technical field [0001] The invention relates to the field of injection mold devices, in particular to a hot runner injection mold device for inclined gates. Background technique [0002] Hot runner molds are widely used in various industrial developed countries and regions in the world today. Hot runner molds have many advantages, which can reduce waste and improve product quality. During the hot runner mold molding process, the temperature of the plastic melt is accurately controlled in the runner system. Plastic can flow into each cavity in a more uniform state, resulting in parts of consistent quality. The gate quality of the parts formed by the hot runner is good, the residual stress is low after demoulding, and the deformation of the parts is small. Therefore, many high-quality products on the market are produced by hot runner molds. For example, many plastic parts in familiar MOTOROLA mobile phones, HP printers, and DELL laptops are made of hot runner molds. [000...

Problems solved by technology

[0003] However, when the existing hot runner injection mold device for inclined gate is used, because the product is formed by hot runner injection molding, it is easy to cause the mold temperature to be too high and the cooling time to be slow, which is not conducive to the protection of the injection mold, and it is easy to cause damage to the workshop. The temperature is too high and the working environment is bad
