Abstract

The utility model relates to a cooling mechanism, in particular to a cooling mechanism for a hot runner die. The cooling mechanism for the hot runner die comprises a hot runner spray nozzle. The hot runner spray nozzle is arranged in a hot runner insert. A cooling mechanism is arranged in the hot runner insert and comprises a cooling water inlet, a cooling water outlet and a cooling water circuit; the cooling water inlet, the cooling water outlet and the cooling water circuit are communicated; and the hot runner spray nozzle is surrounded by the cooling water circuit. The cooling mechanism for the hot runner die has a simple structure. The product period is shortened. The production efficiency is improved.

Description

The cooling body that is used for hot runner mould
Technical field
The utility model patent relates to a kind of cooling body, relates in particular to the cooling body that is used for hot runner mould
Background technology
Present traditional hot-runner nozzle temperature is higher, if do not design cooling system near nozzle, can cause mould gate position temperature height, is not easy cooling, has both prolonged mold cooling time, also easily produces the phenomenon of reeling off raw silk from cocoons.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and near a kind of temperature of product cast gate that effectively reduces is provided, and shortens the cooling body that is used for hot runner mould in formed product cycle.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cooling body that is used for hot runner mould, comprise hot-runner nozzle, described hot-runner nozzle is located in the hot flow path mold insert, be provided with cooling body in the described hot flow path mold insert, described cooling body comprises cooling water inlet, coolant outlet and cooling water channel, described cooling water inlet, coolant outlet and cooling water channel are connected, and described cooling water channel is around hot-runner nozzle.To having increased hot flow path mold insert and independent cooling water channel thereof near the hot runner mould nozzle, reduced near the temperature of product cast gate, shortened the cycle of formed product, improved production efficiency, also can prevent the phenomenon of reeling off raw silk from cocoons.
As preferably, the sidewall of described cooling water channel and hot flow path mold insert is conducted, and is provided with the water route plug at the conducting orifice place, is provided with four water route plugs in the described cooling water channel.
As preferably, described hot flow path mold insert fixes by screw and mould, and the knuckle of described hot flow path mold insert is a fillet.
Therefore, the cooling body that is used for hot runner mould of the present utility model, simple in structure, shorten production life cycle, enhance productivity.
