In order to solve the above technical problems, the utility model provides a kind of small sand core three-in-one mould of bevel housing,
Include the upper die and lower die of mutually opposed installation, be respectively arranged with mutually independent die cavity in the upper die and lower die, it is described on
It is also respectively provided in mould and lower die and penetrates Sha Kou with what the die cavity was respectively communicated with, penetrating in sand mouth and lower die in the upper mold
It is semicircle to penetrate Sha Kou, mandril is respectively provided with around the die cavity in die cavity and lower die in the upper mold, described
Exhaust passage is provided between 6 die cavitys in lower die, the exhaust passage runs through the lower die, is additionally provided in the lower die
The air discharge duct connected respectively with 6 die cavitys and the exhaust passage.
More preferably, the quantity of the die cavity is for 6 and identical two-by-two.
More preferably, the quadrangle in the upper die and lower die is both provided with release link.
More preferably, the diagonal of the upper die and lower die is accordingly respectively arranged with two positioning pins.
More preferably, the air discharge duct is 1~2, depth 0.2mm.
More preferably, the depth of the exhaust passage is 0.8mm.
More preferably, the gap of the mandril and jogger hole is 0.15mm.
Compared with the prior art, the beneficial effects of the utility model are：
1st, by setting 6 identical and mutually independent two-by-two die cavitys in the upper die and lower die of one set of die, in this way may be used
Realize that it is two pieces to make three kinds of small sand cores and each small sand core simultaneously in one set of die, so as to substantially reduce being fabricated to for mold
This, while the quantity for occupying core shooting machine equipment is reduced, and then increase production chains, labour degree is reduced, improves production efficiency；
2nd, an exhaust passage for running through entire mold is set by the centre position of 6 independent die cavitys in lower die,
Simultaneously setting connect respectively with 6 independent die cavitys and exhaust passage together or twice air discharge duct, can make in this way die cavity exhaust lead to
It freely and is independent of each other, so as to improve the yield rate of small sand core.
Description of the drawings
Fig. 1 is a kind of structure diagram of the small sand core three-in-one mould upper mold of bevel housing.
Fig. 2 is a kind of structure diagram of the small sand core three-in-one mould lower die of bevel housing.
It illustrates：1- upper molds, 11- release links, 12- penetrate Sha Kou, 13- mandrils, 14- die cavitys, 15- positioning pins, 2- lower dies,
21- penetrates Sha Kou, 22- mandrils, 23- die cavitys, 24- exhaust passages, 25- air discharge ducts, 26- release links, 27- positioning pins.
Specific embodiment
The utility model is further described with preferred embodiment below in conjunction with the accompanying drawings.
It is a kind of structure diagram of the small sand core three-in-one mould upper mold of bevel housing as shown in Figure 1, including 6 moulds
Chamber 14, this 6 die cavitys 14 are identical and mutual indepedent two-by-two, also in each die cavity 14 around be both provided with mandril 13,
Gap setting between the mandril 13 and jogger hole is 0.15mm.It further includes in the upper mold 1 and is penetrated with what 6 die cavitys 14 were respectively communicated with
Sand mouth 12, it is semicircle that these, which penetrate sand mouth 12,.The quadrangle of upper mold 1 is provided with release link 11, in addition upper mold 1 one of them
There are two positioning pins 15 for diagonal upper setting.
A kind of structure diagram of the small sand core three-in-one mould lower die of bevel housing is illustrated in figure 2, including 6 moulds
Chamber 23, this 6 die cavitys 23 are identical and mutual indepedent two-by-two, also in each die cavity 23 around be both provided with mandril 22,
Gap setting between the mandril 22 and jogger hole is 0.15mm.It further includes in the lower die 2 and is penetrated with what 6 die cavitys 23 were respectively communicated with
Sand mouth 21, it is semicircle that these, which penetrate sand mouth 21,.The quadrangle of lower die 2 is provided with release link 26, in addition lower die 2 one of them
There are two positioning pins 27 for diagonal upper setting.An exhaust passage 24 for running through entire lower die 2, the row are further included in the lower die 2
Gas channel 24 is arranged between 6 die cavitys 23 and area is big as possible, and in addition the depth of the exhaust passage 24 is set as 0.8mm.
Be additionally provided in lower die 2 connected respectively with 6 independent die cavitys 23 and exhaust passage 24 together or twice air discharge duct 25, the row
The depth of air drain 25 is set as 0.2mm.
The 2 mutually opposed installation of above-mentioned upper mold 1 and lower die, therefore the die cavity 23 in the die cavity 14 and lower die 2 in upper mold 1 can be one by one
It is corresponding, three kinds of small sand cores can be produced in this way in one set of die, and each sand core is this part.Using the mould in the utility model
Tool can substantially reduce the cost of manufacture of mold, while reduce the quantity for occupying core shooting machine equipment, and then increase production chains, drop
Low labour degree improves production efficiency.In addition, die cavity 23 in die cavity 14 and lower die 2 in upper mold 1 lower die simultaneously independently of each other
The exhaust of die cavity 23 in 2 is not interfere with each other independently of each other yet, and each die cavity 23 can in this way reached in precoated sand cavity filling process
Double-exhausting effect, so as to improve the yield rate of small sand core.
The producing principle of the utility model is as follows：The utility model mold is installed on shell molding machine, checks Plant in good condition
Afterwards, mold heater switch is opened, heating tube heats die cavity, after mold temperature reaches set temperature, starts coremaking；Upper and lower mould
Precoated sand in the sand hopper of both sides is injected the die cavity of mold by molding, both sides sand-shooting head compaction mold, compressed air by penetrating sand mouth
Interior, precoated sand cures in die material, and curing terminates to open upper and lower mould, ejects sand core by mandril, sand core is taken out,
Prepare to start next group of coremaking operation.
The above only expresses the preferred embodiment of the utility model, and description is more specific and detailed, but not
Can the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that the ordinary skill people for this field
For member, without departing from the concept of the premise utility, several deformations can also be made, improves and substitutes, these all belong to
In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
