Abstract

The utility model discloses a needle valve formula cooling hot runner system, including hot mouth body, the point is chewed to hot mouth, runner department, mould, its characterized in that still includes cooling jacket, cooling jacket sets up the outside of runner department. The utility model discloses the cooling water jacket that increases both had done benefit to arranging in mould water route and can guarantee again that the temperature cooling of hot nozzle glue outlet is even, the product defect that the high temperature phenomenon that better avoids appearing in production leads to with spout out uneven scheduling problem.

Description

Needle valve type cooling hot runner system

Technical Field

The utility model relates to a needle valve formula cooling hot runner system belongs to plastic mould technical field.

Background

The valve needle can appear in the big mouth of a river hot mouth of reality needle valve formula and seal not firmly glue in the actual production process, glues a mouthful wire drawing, and the temperature is on the high side, leads to product glue mouthful department to have black line, phenomenon such as yellow, is that the hot tip temperature of chewing is too high to lead to plastics raw materials to decompose under the condition of high temperature and leads to, and present product front end all does not have the water carrying structure. If the temperature of the glue opening is too low, the glue breaking position of the glue opening of the product has a breaking difference. Therefore, how to adapt the glue outlet temperature to the production of the grinding tool product is a problem to be solved by the technical personnel in the field.

Disclosure of Invention

The utility model aims at providing a rational design, the heat of solving among the prior art is chewed the point high-temperature that leads to and is penetrated gluey unbalance, technical problem such as product appearance colour difference is obvious.

In order to realize the above object, the utility model provides a needle valve formula cooling hot runner system, including hot mouth body, the point is chewed to heat, runner department, the mould still includes cooling water jacket, cooling water jacket sets up the outside of runner department.

As an improvement to the above technical solution, the cooling water jacket is disposed in a mold cavity of the mold, and the cooling water jacket and the mold cavity form a cavity.

As an improvement on the technical scheme, the die is provided with a water inlet hole and a water outlet hole, and the water inlet hole and the water outlet hole are communicated with the cavity.

As an improvement to the above technical solution, the cooling water jacket is screwed with the gate driver.

Compared with the prior art, the beneficial effects of the utility model are that: the cooling water jacket added in the mold cavity of the mold is beneficial to the arrangement of a mold water path and can ensure the uniform cooling of the temperature of the hot nozzle glue outlet, thereby better avoiding the problems of product defects, unbalanced injection and the like caused by high temperature phenomenon in the production.
