Abstract
The invention discloses an improved structure of a hot runner valve disc. The improved structure comprises mold cavity plates, the valve disc, a valve needle, a horizontal runner and a vertical runner, wherein the horizontal runner and the vertical runner are formed between the mold cavity plates. The valve disc is arranged in the vertical runner, the center of the valve disc is provided with a valve needle hole along the axis of the valve disc, the valve needle is arranged in the valve needle hole, one end of the horizontal runner is communicated with the valve needle hole, the upper side face of the valve disc is provided with a valve disc washer, and the center of the valve disc washer, corresponding to the valve needle hole of the valve disc, is provided with a valve needle hole consistent with the valve needle hole of the valve disc. The valve disc is simple in structure, can effectively avoid upward-overflowing of solutions and stuck phenomena of the valve needle and the like, and improves molding quality.
Description
Technical field
The present invention relates to the hot flow path field, relate in particular to a kind of hot flow path valve disc structure-improved.
Background technology
At present, the hot flow path valve disc that uses, it is higher to temperature in melt liquid is flowed through horizontal run, usually cause solution along the needle hole overflow in valve disc to the valve disc upper side, when spillage run up to a certain amount of just may occur the sclerosis be set on the valve disc upper side, thereby cause needle stuck, have a strong impact on Forming Quality.
Summary of the invention
In order to overcome defects, the invention provides a kind of hot flow path valve disc structure-improved, this valve disc is not only simple in structure, and can effectively avoid the phenomenons such as solution overflow, needle be stuck, improves Forming Quality.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of hot flow path valve disc structure-improved, comprise mould an actor's rendering of an operatic tune plate, valve disc, needle and be formed at horizontal run and vertical runner between mould an actor's rendering of an operatic tune plate, described valve disc is placed in vertical runner, described valve disc center is provided with the needle hole along its axis, described needle is placed in this needle hole, described horizontal run one end and the hole conducting of described needle, be provided with the valve disc pad at described valve disc upper side, the place, needle hole of this corresponding described valve disc in valve disc pad center is provided with the needle hole consistent with it.Like this, there be stopping and cooling effect of valve disc pad, can avoid melt liquid upwards to overflow valve disc upper side and curing molding obstruction.
As a further improvement on the present invention, described valve disc pad is rounded, and is provided with semicircle breach at its corresponding valve disc fixing rivet place.
The invention has the beneficial effects as follows: by the corresponding valve disc pad that is provided with the needle hole on the valve disc upper side, effective temperature-reducing and stop that the melt liquid upper reaches overflows, thus avoid needle stuck, improve forming quality of products.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is valve disc gasket construction schematic diagram of the present invention.
By reference to the accompanying drawings, make the following instructions:
1---mould an actor's rendering of an operatic tune plate 2---valve disc
3---horizontal run 4---are runner vertically
5---needle hole 6---valve disc pad
The specific embodiment
A kind of hot flow path valve disc structure-improved, comprise mould an actor's rendering of an operatic tune plate 1, valve disc 2, needle and be formed at horizontal run 3 and vertical runner 4 between mould an actor's rendering of an operatic tune plate, described valve disc is placed in described vertical runner, described valve disc center is provided with the needle hole 5 along its axis, described needle is placed in this needle hole, described horizontal run one end and the hole conducting of described needle, be provided with valve disc pad 6 at described valve disc upper side, the place, needle hole of this corresponding described valve disc in valve disc pad center is provided with the needle hole consistent with it.Like this, there be stopping and cooling effect of valve disc pad, can avoid melt liquid upwards to overflow valve disc upper side and curing molding obstruction.
Preferably, above-mentioned valve disc pad is rounded, and is provided with semicircle breach at its corresponding valve disc fixing rivet place.
