Description
Technical field
The present invention relates to Hot runner Technology field, more specifically, it relates to a kind of cooling water jacket structure of injection mold.
Background technology
The plastics that in general plastic mould is processed all are thermoplastic raw materials, and during production, injection machine adds plastic raw materials
Heat arrives required temperature, makes its fusing, then the raw material of fusing is injected into the die cavity of plastic mould, is melted in mold cavity
The plastic raw materials of change cooled and solidified, sizing in mould, then mold, eject the part of shaping.In hot flow path heater,
The temperature of hot nozzle is very high, causes cast gate position localized hyperthermia, and during product cooling, melt will be because of temperature at cast gate
Too high solidification is slow, influences the disconnected glue of cast gate, causes the product surface at cast gate PUR trace, yield rate easily occur
It is low, and injection cycle is grown.
But the method for existing TOP-TIP Re Zui heads increase cooling fortune water is：Close to nozzle core on cavityplate
Two straight cooling water channels of place processing, be connected with the water route on mould, but water route is straight-through water route, to nozzle core
Cooling effect is undesirable；And when using the annular water channel being centered around around nozzle head, because difficulty of processing is big, processing cost is too high,
It should not use.
The content of the invention
In view of the deficienciess of the prior art, it is an object of the invention to provide a kind of cooling water noose of injection mold
Structure, it has good cooling results, the simple advantage of processing.
To achieve the above object, the invention provides following technical scheme：
A kind of cooling water jacket structure of injection mold, including solid plate and hot nozzle, the cover half plate surface are provided with shoulder hole,
The shoulder hole includes upper hole and lower opening, and the fortune water jacket being bonded with the inwall of lower opening, the hot nozzle are provided with the lower opening
Through fortune water jacket, the bottom wall of the lower opening is provided with the resigning hole that heat supply nozzle passes through, and the fortune water jacket top is coaxially arranged with
The locating piece to be fitted with upper hole, the fortune water jacket outer circle wall are provided with tank, formed between the tank and lower opening inwall
Cooling water channel, the water inlet pipe and return pipe communicated with cooling water channel is respectively arranged with the solid plate.
By using above-mentioned technical proposal, upper hole and lower opening are used for location and installation fortune water jacket, and resigning hole is used for heat supply nozzle
Pass through, and at the cast gate for reaching lower section；By opening up tank in the circumferential wall of fortune water jacket, make between tank and the inwall of lower opening
Cooling water channel is formed, the solid plate at cast gate can be pointed to and cooled down, reduces heat transfer, makes solid plate not continue to rise
Temperature；In addition it can also make quickly to cool down at cast gate, be easy to disconnected glue, improve operating efficiency；Water route is in surround shape, cold compared to straight water route
But effect is good；Compared to annular water channel is processed in solid plate, transport that the processing mode of water jacket is simple, and processing cost is low.
Further, the tank in the shape of a spiral and be wound on fortune water jacket outer circle wall on, the water inlet pipe and return pipe
The both ends with tank are connected respectively.
By using above-mentioned technical proposal, the both ends of water inlet pipe and return pipe respectively with tank are connected, and current is flowed
Through whole cooling water channel, by setting spiral helicine tank, the film-cooled heat of cooling water channel can be increased, further increase cooling
Effect.
Further, the outer circle wall that the fortune water jacket is located above tank is provided with first annular groove, first ring
Shape groove is embedded with the first sealing ring being adjacent to lower opening.
By using above-mentioned technical proposal, due to certain gap be present between fortune water jacket and lower opening inwall, show in capillary
As under effect, current easily spread in gap, cause the generation of water leakage situation；By setting resistant to elevated temperatures first sealing ring,
The water resistance overflowed out of tank can be interposed between below the first sealing ring, prevent leak.
Further, the second annular groove is coaxially arranged with the end face that the fortune water jacket is bonded with the bottom wall of lower opening, it is described
The second sealing ring being adjacent to the bottom wall of lower opening is provided with second annular groove.
By using above-mentioned technical proposal, due to capillarity, flow downwardly in resigning hole, in some instances it may even be possible to flow into cast gate
Place, causes damage of product；By setting the second sealing ring, current can be obstructed in fortune water jacket bottom wall, prevent current flow into from allowing
In the hole of position, yield rate is improved.
Further, the hot nozzle includes nozzle core, and the outer coaxial sleeve of the nozzle core, which is provided with, to be extended downward into outside hot nozzle
Gland, the outer circle wall that the gland is located at outside hot nozzle is coaxially arranged with to offset with fortune water jacket inwall, and will transport water jacket stretching
Pushing out ring on lower opening inwall.
By using above-mentioned technical proposal, during installation, first fortune water jacket is arranged in shoulder hole, then loaded gland,
By interference fit, make pushing out ring be caught in fortune water jacket you, and support greatly, make the connection of fortune water jacket and lower opening inwall closer, enter
And the first sealing ring is further compressed, increase sealing effectiveness；Gland can also carry out location and installation to nozzle core.
Further, the locating piece is connected by bolt with solid plate, and fortune water jacket is pushed against downwards to the bottom of lower opening
Wall.
By using above-mentioned technical proposal, locating piece is connected with solid plate by bolt, it is downward for water jacket will be transported
Push against, and the second sealing ring of fortune water jacket bottom is further compressed, so as to increase sealing effectiveness.
Further, the locating piece side is provided with positioning plane, and the upper hole profile is consistent with locating piece profile.
By using above-mentioned technical proposal, plane is positioned by setting, will fortune water jacket load in shoulder hole when, for pair
Locating piece is positioned, and is easy to screw to be aligned, and positions plane in addition and also has rotation stop effect.
In summary, the invention has the advantages that：
1st, by setting spiral helicine tank on fortune water jacket, there is good cooling effect, fortune water jacket processing is simple, is processed into
This is low；
2nd, by setting the first sealing ring and the second sealing ring, good sealing effectiveness can be kept, avoids leak；
3rd, by setting gland further to increase sealing.
