Abstract
Many runners of door and window frame needle valve formula are with step -by -step gluey mechanism, cover half and movable mould including injection mold set up the runner plate on the cover half, set up the runner in the cover half, injection moulding's door and window frame in cover half and movable mould, its characterized in that: the cover half in set up 10 above runners, the runner of hiding is connected down respectively to each runner, sets up the hydro -cylinder on runner plate upper portion with the corresponding position of runner, the needle valve is connected to the piston rod of hydro -cylinder, the needle valve cooperatees with the end opening of runner. Through setting up the runner more than 10 in the cover half, and every runner passes through the hydro -cylinder and drives the needle valve shutoff to each position of guaranteeing the door and window frame can both obtain abundant moulding plastics, defects such as weld mark that can the long and narrow shape working of plastics surface of effectual elimination, sink mark, cold burden spot, and the hide runner of formula, and the door and window frame back that makes the trace of moulding plastics hide, thus guarantee that its appearance is pleasing to the eye.
Description
Technical field
This utility model is related to injection mold, and the more particularly to many cast gates of sash needle valve are with stepping gluing mechanism.
Background technology
Sash working of plastics on automobile is overall long and narrow and again relatively thin due to it, and when being therefore molded, sizing material is in die cavity
Poor fluidity, if injection pressure is not enough or cast gate is few, is easily caused the sash yield rate of injection mo(u)lding, there is welding on surface
Trace and slitter edge, are outward appearance gadget additionally, due to sash, and the cast gate of existing injection mold is usually located at working of plastics front, is molded into
There is cast gate trace on the sash surface of type, and impact product is attractive in appearance.
Content of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art to exist, and provides a kind of injection trace to be located at working of plastics
The back side, weldless trace, the many cast gates of sash needle valve making working of plastics good looking appearance are with stepping gluing mechanism.
The many cast gates of this utility model sash needle valve with the technical scheme of stepping gluing mechanism are：Determining including injection mold
Mould and dynamic model, cover half arranges runner plate, arranges cast gate, the sash of injection mo(u)lding in fixed half and moving half, it is special in cover half
Levy and be：In described cover half arrange more than 10 cast gates, connect tunnel gate under each cast gate respectively, runner plate top with pour
Mouth opposite position setting oil cylinder, the piston rod of oil cylinder connects needle-valve, and needle-valve is matched with the lower mouth of cast gate.
The utility model discloses a kind of many cast gates of sash needle valve are with stepping gluing mechanism, when injection mold is started working
When, by the barrel of injection machine, the sizing material that heat is melted is delivered to the runner plate of injection mold, sizing material is delivered to each and pours by runner plate
In mouthful, now oil cylinder drives needle-valve to block the lower mouth of cast gate, when filling sizing material in each cast gate, and reaches certain pressure
When, oil cylinder drives needle-valve upwards, so that the lower mouth of cast gate is opened, now in all cast gates, sizing material is injected simultaneously in die cavity, realizes same
Stepping glue.The many cast gates of this programme sash needle valve with stepping gluing mechanism, by the cast gate of setting more than 10 in cover half, and
Each cast gate drives needle-valve closure by oil cylinder, thus ensureing that each position of sash can be sufficiently molded, and can have
The defects such as the weld mark of elimination thin-and-long plastic part surface of effect, shrink mark, cold burden speckle, and the cast gate of submarine, make injection trace hidden
The sash back side hidden, thus ensure its good looking appearance.
The many cast gates of this utility model sash needle valve, with stepping gluing mechanism, arrange 12 cast gates in described cover half.Root
According to the length of sash, rationally setting cast gate quantity.
Brief description
Fig. 1 is the schematic perspective view with stepping gluing mechanism for the many cast gates of sash needle valve；
Fig. 2 is the structural representation with stepping gluing mechanism for the many cast gates of sash needle valve.
Specific embodiment
This utility model is related to a kind of many cast gates of sash needle valve with stepping gluing mechanism, as shown in Fig. 1 Fig. 2, including
The fixed half and moving half of injection mold, cover half arranges runner plate 1, arranges cast gate 2, injection mo(u)lding in fixed half and moving half in cover half
Sash 3 it is characterised in that：In described cover half, more than 10 cast gates 2 are set, under each cast gate, connect tunnel gate 4 respectively,
Oil cylinder 5 is set with cast gate opposite position on runner plate 1 top, and the piston rod of oil cylinder connects needle-valve 6, under needle-valve and cast gate 2
Mouth matches.When injection mold is started working, by the barrel of injection machine, the sizing material that heat is melted is delivered to the runner of injection mold
Plate 1, sizing material is delivered in each cast gate 2 runner plate, and now oil cylinder 5 drives needle-valve 6 to block the lower mouth of cast gate 2, when each
Fill sizing material in cast gate, and when reaching certain pressure, oil cylinder 5 drives needle-valve 6 upwards, so that the lower mouth of cast gate 2 is opened, now institute
There is sizing material in cast gate to be injected simultaneously in die cavity, realize with stepping glue.The many cast gates of this programme sash needle valve with stepping gluing mechanism,
By arranging the cast gate 2 of more than 10 in cover half, and each cast gate drives needle-valve 6 to block, thus ensureing door and window by oil cylinder 5
Each position of frame can be sufficiently molded, and can effectively eliminate the weld mark of thin-and-long plastic part surface, shrink mark, cold burden
The defects such as speckle, and the cast gate of submarine, make the sash back side that injection trace is hidden, thus ensureing its good looking appearance.Described determines
12 cast gates 2 are set in mould.According to the length of sash, rationally setting cast gate 2 quantity.
