Description
Technical field
The utility model relates to a kind of hot runner mechanism, particularly relates to a kind of needle valve type hot runner mechanism for upside-down mounting mould, for mould.
Background technology
The hot flow path of current traditional upside-down mounting mould needle valve, easily occur that product appearance is bad, shaping adjustment technology difficulty is larger, and final products defective products is high.
Chinese patent 201020660946.8, discloses a kind of Novel inverse installation die, it is characterized in that: it is primarily of cover half, dynamic model, guide pillar, guide pin bushing, pull bar composition; Described fixed half and moving half is slipped by guide pillar, guide pin bushing; Described cover half comprises fixed die ejector, cover half push rod fixed head, cover half die cavity, and one end of fixed die ejector is arranged on cover half push rod fixed head, and the other end of fixed die ejector penetrates cover half die cavity; Described dynamic model comprises dynamic model thimble, dynamic model die cavity, and one end of dynamic model thimble penetrates dynamic model die cavity, and dynamic model die cavity is provided with multiple pore; On the cover half push rod fixed head that the two ends of described pull bar are articulated in cover half respectively and dynamic model.This structure is relatively traditional, causes product quality to improve.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, a kind of compact conformation is provided, by the needle of upper end needle and lower end needle forming station stepwise, injection moulding production stability and bad order rate are significantly increased, the needle valve type hot runner mechanism for upside-down mounting mould that production cost is reduced.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of needle valve type hot runner mechanism for upside-down mounting mould, comprise product, also comprise hot flow path mold insert and Re Zui, described product is positioned at the bottom of hot flow path mold insert, the lower end of described hot mouth is located in hot flow path mold insert, the bottom of described hot mouth is provided with sprue bush, and the bottom of described sprue bush is provided with upper end needle, and the bottom of described upper end needle is provided with the lower end needle extended to product.
As preferably, described lower end needle and upper end needle are integrated distribution, and described sprue bush and hot mouth are integrated distribution.
As preferably, the diameter of described lower end needle is less than the diameter of upper end needle.
The processing of this needle is simple, and easy accessibility, result of use is obvious.
Therefore, the needle valve type hot runner mechanism for upside-down mounting mould of the present utility model, compact conformation, reduces costs, and promotes working (machining) efficiency high, improves mould Adapter Property.
