Abstract
The utility model discloses a low-pressure casting mould which comprises an upper mould, a fixed seat, a lower mould, a lower sprue sleeve and an upper sprue sleeve, wherein the middle of the upper mould is provided with a mould cavity, the lower mould is fixedly mounted on the upper portion of the fixed seat, the lower sprue sleeve is connected with a liquid raising tube, and the upper sprue sleeve is coaxially arranged above the lower sprue sleeve. The lower mould is provided with a sprue communicated with the mould cavity and a sprue sleeve mounting hole coaxial with the sprue, the upper sprue sleeve is mounted in the sprue sleeve mounting hole in a sleeved mode, the middle of the upper mould is provided with a first taper hole, a big-head end of the first taper hole is close to the mould cavity, the fixed seat is provided with a mounting hole used for the lower sprue sleeve to penetrate through, the middle of the lower sprue sleeve is provided with a second tape hole, and the small-head end of the second taper hole is close the upper sprue sleeve. When the low-pressure casting mould is subjected to pouring, melt enters into the mould cavity through the liquid raising tube, the lower sprue sleeve, the upper sprue sleeve and the sprue, and the low-pressure casting mould ensures that the melt does not easily solidify during the whole process. The upper sprue sleeve and the lower sprue sleeve are made of ceramic materials, and therefore the service life of the upper sprue sleeve and the lower sprue sleeve is prolonged.
Description
Technical field
The utility model relates to a kind of processing equipment, is specifically related to a kind of low pressure casting die.
Background technology
Existing low pressure casting die is when cast, liquation directly injects in the die cavity through stalk and cast gate, filling type, boosting, in the pressure maintaining period, by the liquation in the stalk cast product carried out feeding, because the bore of stalk is normally fixing, when cast gate is excessive, can increase the product setting time, reduce the product yield of production efficiency and product, and if the dwell time long, be easy to cause liquation condensing in stalk, greatly shorten the service life of stalk.And existing sprue bush adopts ferrous material to make, and it is subject to the corrosion of liquation, has shortened the service life of sprue bush.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of die life, low pressure casting die that production efficiency is high of improving.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of low pressure casting die, it comprises that the middle part offers the patrix of die cavity, holder, the counterdie of fixed installation holder top, the submarine gate cover that is connected with stalk and the coaxial upper sprue bush that is arranged on submarine gate cover top, offer the cast gate that is connected with die cavity and the sprue bush installing hole coaxial with cast gate on the counterdie, in the upper sprue bush suit sprue bush installing hole, the middle part of upper sprue bush offers the first bellmouth, the stub end of this first bellmouth is near die cavity, offer the installing hole that passes for submarine gate cover on the holder, the middle part of submarine gate cover offers the second bellmouth, and the little head end of this second bellmouth is near upper sprue bush.
Wherein, sprue bush and submarine gate cover are made by ceramic material on this.
Wherein, be provided with screen pack between upper sprue bush and the counterdie.
Wherein, be filled with heat-insulation layer between submarine gate cover and the holder.
(3) beneficial effect
Compared with prior art, the utility model is when cast, and liquation enters in the die cavity through stalk, submarine gate cover, upper sprue bush and cast gate, has guaranteed that solution is difficult for solidifying in whole process; And upper sprue bush and submarine gate cover adopt ceramic material to make, and prolonged the service life of upper sprue bush and submarine gate cover.
Description of drawings
Fig. 1 is the structural representation of the utility model low pressure casting die.

Should upper sprue bush 3 and submarine gate cover 4 made by ceramic material, this structural design has prolonged service life of upper sprue bush and submarine gate cover.
Be provided with screen pack 6 between upper sprue bush 3 and the counterdie 2, so effectively avoided holding furnace and slag inclusion upper, that sprue bush is interior to enter in the die cavity, improved the quality of foundry goods.
Be filled with heat-insulation layer 7 between submarine gate cover 4 and the holder 5, improved the heat-insulating property of submarine gate cover.
It below only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
