Description
Technical field
The present invention relates to Low Pressure Casting Technology field, specially a kind of improved low pressure casting die.
Background technology
The mould that current low pressure casting is used, is mostly steam vent connection exhaust plug structure, when type is filled, it is easy to can quilt
Block, cause die venting bad, the body of casting dense structure's property and mechanical strength produced be not high, qualification rate is low, is taking
It is mostly during the body of casting by the upper mould frictional force pull-up body of casting, is so easy to unexpected situation about coming off occur.
The content of the invention
It is an object of the invention to provide a kind of improved low pressure casting die, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of improved low pressure casting die, including lid
Plate, pull bar, suspension rod, discharge duct, venting plug, core, upper mould, die cavity, inlet, oil cooling service pipe, pull bar motion bar and lower mould,
The die cavity is located between upper die and lower die, and the lower mould middle part is provided with inlet and lower mould top is provided with oil cooling service pipe, institute
State mould two ends and be mounted on pull bar and suspension rod, the pull bar bottom is provided with pull bar motion bar structure, and the upper mould middle part is provided with
Discharge duct, discharge duct top is provided with venting plug, and the upper mould bottom is provided with core, the cover plate by pull bar and
Hanger erection is in upper mould upper end.
Preferably, the upper mould bottom is provided with equidistant steam vent.
Preferably, the inlet inner side is provided with ceramic protective sleeve.
Preferably, the lower mould top is provided with staggered parallel between a plurality of oil cooling service pipe and oil cooling service pipe.
Compared with prior art, the beneficial effects of the invention are as follows：The improved low pressure casting die, realizes casting
Consecutive solidification, simplifies the complexity of operation, and can effectively ensure casting fills type effect, eliminates the casting such as volume gas, slag inclusion and lacks
Fall into, while oil cooling device is avoided there are the defects such as shrinkage cavity and porosity in body of casting cooling procedure, improve production efficiency, while
Improve the qualification rate of the body of casting.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of improved low pressure casting die, including cover plate 1, drawing
Bar 2, suspension rod 3, discharge duct 4, venting plug 5, core 6, upper mould 7, die cavity 8, inlet 9, oil cooling service pipe 10, pull bar motion bar 11
With lower mould 12, positioned between upper mould 7 and lower mould 12, the middle part of the lower mould 12 is provided with inlet 9 and the top of lower mould 12 to the die cavity 8
Oil cooling service pipe 10 is installed, the top of the lower mould 12 is provided with staggered parallel between a plurality of oil cooling service pipe 10 and oil cooling service pipe 10,
The inner side of the inlet 9 is provided with ceramic protective sleeve, and the two ends of upper mould 7 are mounted on pull bar 2 and suspension rod 3, the bottom of the pull bar 2
The structure of pull bar motion bar 11 is provided with, the middle part of the upper mould 7 is provided with discharge duct 4, and the bottom of upper mould 7 is provided with equidistant exhaust
Hole, the top of the discharge duct 4 is provided with venting plug 5, and the bottom of upper mould 7 is provided with core 6, and the cover plate 1 passes through the He of pull bar 2
Suspension rod 3 is arranged on the upper end of upper mould 7.
The present invention is improved：The bottom of lower mould 12 add oil cooling service pipe 10, can effectively avoid water meson or its
His meson causes the defects such as shrinkage cavity and porosity when being cooled down to the body of casting, and cooling velocity is fast, improve production efficiency.
The present invention is improved：Discharge duct 4 is provided with the middle part of upper mould 7 and top is provided with venting plug 5, the structural improvement
Original exhaust structure, it is to avoid molten metal blocks blast pipe, causes exhaust bad and body of casting dense structure's property and machinery occurs
Intensity situation not high,
The present invention is improved：The structure of pull bar motion bar 11 is provided with the bottom of pull bar 2, the pull bar motion bar 11 is flexible, is taking
During the body of casting, first drive pull bar motion bar 11 to bend, buckle the body of casting, be pulled upwardly mould 7, after upper mould 7 is removed, drive pull bar to live
Lever 11 is straightened, and removes the body of casting.Improve it is original by the upper frictional force of mould 7 by body of casting pull-up, it is to avoid taking the mistake of the body of casting
The body of casting comes off and deforms caused by vibration or other reasonses in journey, improves the qualification rate of the body of casting.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be in other specific forms realized.Therefore, no matter
