Abstract
A kind of core structure for processing workpiece with hole, including core, core inside are provided with cavity, and core bottom is provided with down sprue pipe, and cavity side side wall is provided with branch's pouring channel tube, and described branch's pouring channel tube one end connects cavity, and the other end is stretched out outside core；The core is " recessed " type structure, and the port position of core bottom is provided with cover plate, and core port both ends pass through bolt and cover plate fastens；Designed by the special construction of core, gas can be stayed in molten iron casting in cavity, effectively prevent and bubble is produced on product, increase the qualification rate of product.
Description
Technical field
Casting technology field is the utility model is related to, is specifically related to a kind of core structure for processing workpiece with hole.
Background technology
Process during pulley of the workpiece with hole as produced magnesium iron, magnesium iron water and the pouring channel tube of cast produce gas, gas
Die cavity is flowed into molten iron, the product of cast forms very big stomata on pouring channel tube periphery.It can not repair on request, cause percent defective
It is high, reduce production efficiency.
The content of the invention
In view of above-mentioned technical problem, the utility model provides a kind of core structure for processing workpiece with hole, can avoid
Gas produces on product, effectively prevents product from bubble occur, and product qualified rate reaches 100%.
To achieve these goals, technical scheme is used by the utility model：A kind of core for processing workpiece with hole
Structure, including core, core inside are provided with cavity, and core bottom is provided with down sprue pipe, and cavity side side wall is poured provided with branch
Deferent, described branch's pouring channel tube one end connect cavity, and the other end is stretched out outside core；
The core is provided with cover plate for " recessed " type structure, the port position of core bottom, and core port both ends pass through spiral shell
Bolt fastens with cover plate；
It is cavity structure in the core, cavity inside is provided with evaporative pattern；
Described cavity is cylindric；
A kind of core structure of described processing workpiece with hole, in addition to bend pipe pouring channel tube, bend pipe pouring channel tube and down sprue
Pipe connects；
A kind of core structure of described processing workpiece with hole, in addition to circular cross-runner, bend pipe pouring channel tube are connected to ring
On shape cross gate；
A kind of core structure of described processing workpiece with hole, it is to set some bend pipe pouring channel tubes and main pouring channel tube, institute
State some bend pipe pouring channel tubes to be both connected on circular cross-runner, circular cross-runner is connected with main pouring channel tube；
The casting technique of the workpiece with hole is；
Take square bottomless mould to fill resin sand, cylindrical mold is put into resin sand center, adhesive is then added, treats
Taken out after sand shaping；The one end of the core of taking-up with recess is covered into cover plate, and tightened by bolt, forms core cavity knot
Structure；Down sprue pipe is set in cavity bottom, on the cavity sidewalls pre-buried branch's pouring channel tube；Said structure is passed through into down sprue Guan Lian
One end of bend pipe pouring channel tube is connected to, the bend pipe pouring channel tube other end is connected on circular cross-runner；Molten iron flows into from main pouring channel tube, leads to
Cross circular cross-runner pipe to be further separated into some bend pipe pouring channel tubes, molten iron bottom is returned into down sprue pipe, and then enters cavity
It is interior, branch's pouring channel tube is then flowed into again, now, the gas in molten iron is stayed in cavity, and molten iron is poured into a mould in each pipe in top,
Work pieces process is completed, is produced after work pieces process in bend pipe pouring channel tube periphery bubble-free.
The casting technique another kind core structure processing technology of the workpiece with hole is：
Cylindrical evaporative pattern is taken, down sprue pipe is welded in evaporative pattern bottom, branch is welded in the side wall of evaporative pattern side and is poured
Deferent；Said structure is positioned in square dies, filling sand is carried out between evaporative pattern and mould, adds adhesive, treats resin sand
After sizing, drying, remove outer mold；Cavity is formed after evaporative pattern disappears in core；Then ring is connected to by down sprue pipe
Shape cross gate, molten iron flow into from main pouring channel tube, are further separated into by circular cross-runner pipe in some bend pipe pouring channel tubes, molten iron bottom
Return into down sprue pipe, and then enter in cavity, be then flowed into branch's pouring channel tube again, now, the gas in molten iron stays in
In cavity.
Designed by the special construction of core, gas can be stayed in molten iron casting in cavity, effectively prevent production
Bubble is produced on product, increases the qualification rate of product.
