In crankcase casting industry, the quality of injection system structure design directly influences the qualification rate of casting.Mesh
Before, the conventional injection system structure of crankcase uses bottom filling, and the running gate system passes through cylinder holes core bottom using iron liquid,
High temperature iron liquid can produce substantial amounts of gas after being contacted with cylinder holes core, if crankcase cylinder holes core because structure need, it is necessary to
It is provided separately, then motion enters die cavity in advance upwards naturally in the gap that generation gas will be between core and core, treats iron liquid completely extremely
When covering gap, gas can not just exclude at this, so that casting produces stomata in this place, after causing crankcase blank to process
There is gas hole defect and scrap, passing rate of processing is low, causes economic loss and product brand honor to reduce.
Utility model content
The purpose of this utility model is：It can be produced after being contacted for high temperature iron liquid in the prior art with cylinder holes core a large amount of
Gas, gap of the gas between core and core enter die cavity in advance, causes crankcase blank gas hole defect occur after processing
And the technical problem scrapped, the utility model provide a kind of crankcase gap bridge cover plate running gate system, the running gate system is provided with
The gap bridge cover plate for preventing iron liquid from being contacted with cylinder holes core, prevent gap of the gas between core and core from causing gas into die cavity in advance
Hole defect, improve passing rate of processing.
The technical solution adopted in the utility model is as follows：
A kind of crankcase gap bridge cover plate running gate system, including bottom plate and several crankcase cylinders set respectively side by side
Hole core, the cylinder holes core are arranged with outside core outside, hollow die cavity, institute are provided between the cylinder holes core and outside core
State and be provided with stacker at the top of bottom plate, cylinder holes core is placed on the stacker, and the bottom plate is provided with for being noted to die cavity
Enter iron liquid enters cast gate and a cast runner, and a cast runner includes being arranged at the feed liquor runner of stacker both sides and through undertaking
The gap bridge runner that seat is set, the feed liquor runner and gap bridge flow passage, it is described enter cast gate be arranged at feed liquor runner and pass a bridge and flow
One of junction in road, the feed liquor runner connect with die cavity, are provided with the top of gap bridge runner for preventing iron liquid and cylinder
The gap bridge cover plate of hole core contact.
Further, the gap bridge cover plate is detachably connected with gap bridge runner.
Further, the stacker is detachably connected with bottom plate.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. the utility model crankcase gap bridge cover plate running gate system is provided with the mistake for preventing that iron liquid from contacting with cylinder holes core
Bridge cover plate, prevent gap of the gas between core and core from entering die cavity in advance, allow iron liquid with gas caused by cylinder holes core with iron
Liquid is flowed, and is emitted in mouth region so as to allow the gas in gas and die cavity in iron liquid to enter, so as to obtain qualified casting, is carried
High passing rate of processing；
2. the utility model running gate system is provided with the crankcase cylinder holes core that several are set respectively side by side, can once pour
Several crankcases are noted, obtained crankcase blank is easily split；
3. the utility model gap bridge cover plate is detachably connected with gap bridge runner, stacker and bottom plate are detachably connected, it is easy to
Gap bridge cover plate and stacker are changed.
