Abstract

The utility model discloses an improved mold cooling device. The improved mold cooling device comprises a bottom mold (1), a water cooling insert (4), a water inflow tube (5) and a water outflow tube (6), wherein an annular groove is formed in a back cavity, corresponding to the center of a wheel, of the bottom mold (1), the water cooling insert (4) is arranged on the annular groove, a cavity is formed between the water cooling insert (4) and the annular groove, the water cooling insert is provided with water inflow holes and water outflow holes, and the water inflow holes and the water outflow holes are distributed in center symmetry. The water inlet of the water inflow tube (5) is blocked, and two through holes (5-1) are symmetrically formed in the side wall of the pipe wall of the water inlet and parallel to the radial cross section of the annular groove. The temperature gradient distribution uniformity in the casting process is effectively improved by the mold cooling device, and the difficulty for controlling process molding is reduced on the premise that cooling strength is guaranteed and the mechanical performance of the wheel center and production efficiency are improved.

Description

Improved equipment for cooling die
Technical field
The utility model relates to mould, particularly equipment for cooling die.
Background technology
Progressively exploration application along with Water Cooling Technology, the methods for cooling that water channel adds stifled weldering is dug at bed die center, to solving the problem of " mechanical performance that cast aluminum-molykote composite material wheel disk final set causes reduces ", obtain better effects, improved the setting rate of core wheel and rising head, improved casting production efficiency.
But this methods for cooling has following problem: the one, and the annular cooling conduit road intensity of cooling of employing " wind hole section " structure is strong and technique controlling difficulty is larger, casting process simulation shows that the thermograde at foundry goods core wheel position has abnormal low temperature region, can cause in forming process the feeding problem of damming, spoke and wheel rim place casting are very easily had a negative impact; The 2nd, the welding stress that produces after machine repeatedly go up at the stifled weldering of water channel welding position and the thermal stress of cold and hot exchange is leaked water channel weld cracking, causes whole bed die to be scrapped, and producing cost wastes and Judge Method in Determining Supplying Risks; The 3rd, singly entering the Inlet and outlet water mode singly going out can have a negative impact to the spoke near water inlet place.
Summary of the invention
Be intended to solve the weak point of above-mentioned waterway cooling structure, the utility model provides a kind of mould water cooling plant that improves the mechanical property at casting production efficiency and wheel disk position.
The technical scheme that the utility model technical solution problem adopts is: improved equipment for cooling die, comprise that bed die, water-cooled are inserted, water inlet pipe, outlet pipe, corresponding wheel center position, bed die back of the body chamber arranges annular groove, water-cooled is set on annular groove inserts, water-cooled insert and annular groove between form cavity, water-cooled is inserted inlet opening, apopore is set, and inlet opening and apopore Central Symmetry distribute.
The water inlet shutoff of described water inlet pipe, water inlet tube wall side is symmetrical arranged two through holes, and through hole plane is parallel with the radial cross-section of annular groove.Guarantee water flow and cooling effect, can realize a water intake mode that enters scene 2.
The utility model carries out rounding to wedge angle position, avoids thermal stress centrostigma, water inlet pipe and water outlet pipe is assembled to water-cooled insert after, corresponding bed die apopore position needs to position in patchhole mistake proofing.
The beneficial effects of the utility model are, use but form of the cooling bed die central water-cooling of inserting, changing the cellular type salient point type of cooling is in the past that water channel is evenly full of the cooling mode of back plane, again in conjunction with controlling bed die cooling and plane and core wheel apart from distance, effectively improve the temperature gradient distribution uniformity of casting process, under the prerequisite that guarantees intensity of cooling raising core wheel mechanical performance and production efficiency, reduced the difficulty that technological forming is controlled; Next has avoided core wheel rising head place in batch production cold and heat succeed each other too violent and cause weld cracking to scrap the situation of whole bed die, has saved Mold Making maintenance cost and has also reduced enterprise's Judge Method in Determining Supplying Risks.
Accompanying drawing explanation
Fig. 1 is background technology bed die central water-cooling die structure dwg.
Fig. 2 is bed die central water-cooling die structure dwg of the present utility model.
Fig. 3 is the water-cooled of the present utility model schematic diagram of inserting.
Fig. 4 is that water-cooled of the present utility model is inserted and inlet tube and outlet tube assembling schematic diagram.
1. bed dies in figure, 2. stifled soldering iron plate, 3. singly enters water inlet pipe, and 4. water-cooled is inserted, 5. water inlet pipe, 5-1. through hole, 6. outlet pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: improved equipment for cooling die, comprise that bed die 1, water-cooled insert 4 and water inlet pipe 5, outlet pipe 6, bed die 1 corresponding wheel center position, back of the body chamber arranges annular groove, water-cooled is set on annular groove and inserts 4, water-cooled insert 4 and annular groove between form cavity, water-cooled is inserted inlet opening, apopore is set, and inlet opening and apopore Central Symmetry distribute.
The water inlet shutoff of described water inlet pipe 5, water inlet tube wall side is symmetrical arranged two through hole 5-1, and two through hole 5-1 planes are parallel with the radial cross-section of annular groove.Guarantee water flow and cooling effect, can realize a water intake mode that enters scene 2.
The utility model carries out rounding to wedge angle position, avoids thermal stress centrostigma, water inlet pipe and water outlet pipe is assembled to water-cooled insert after, corresponding bed die apopore position needs to position in patchhole mistake proofing.
When wheel disk needs are cooling, the water inlet pipe 5 tube wall through hole 5-1s of cooling water by Fig. 2 form two and flow to influent stream and enter in cooling 4 the water channel inserted, after contacting with bed die 1 cooling surface, begin to cool down effect after water channel is full of cooling water, by strong exchange capability of heat and thick large mould heat storage capacity effective cooling wheel center and the rising head of cooling water, after finally by outlet pipe 6 corresponding to bed die 1 apopore, cooling water being discharged, complete cooling.
