Description
Technical field
The invention belongs to metal casting technique field, be specifically related to the parison mold mould of a kind of precast.
Background technology
In casting process, mould is one of mechanism of most critical needed for casting technique, and it the most directly determines casting
The structure of part and the Forming Quality of cast member can also be determined.
In prior art, cast member is often allowed to have most basic structure as first type part, experiences a series of the most again
Processing technique be increasingly becoming qualified product.As can be seen here, the quality of first type part finally determines the quality of product.In reality
In casting process, the liquid metal of high-temperature fusion enters die cavity by running channel, owing to natively having certain volume in die cavity
Gas, when causing cast, this gas cannot be escaped and be mixed with motlten metal and ultimately cause cast member and have substantial amounts of bubble.This
Outward, owing to the volume of mould own is relatively big and structure is often irregular, and the volume of die cavity is less, thus result in liquid metal pole
Easily produce irregular cooling because of the low temperature that had of mould, cause pouring into a mould work and cannot be smoothed out thus cause casting
Part size and problem off quality, virtually add time and the cost of casting technique, reduce the production of cast member
Efficiency, produces enterprise and adversely affects.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that the parison mold mould of a kind of precast, it is possible to
Pre-Anti-bubble is generated by uniformly cooling down size and the quality ensureing cast member.
For solving prior art problem, the invention discloses the parison mold mould of a kind of precast, be used for casting bowl-shape at the beginning of
Type part, including the upper die and lower die of alloy material, the bottom of upper mold has a protuberance matched with the inner surface of first type part,
The top of lower mold has a recess matched with the outer surface of first type part；Upper die and lower die are closely detained by fixing structure
Close, when both fasten, between protuberance and recess, form die cavity；The top of upper mold offers sprue gate and some gas outlets respectively,
Sprue gate is connected with die cavity by running channel, and gas outlet is connected with the top of die cavity by gas off-take.
Preferably, gas off-take is the pyramidal structure that internal diameter is sequentially reduced from bottom to top.
Preferably, sprue gate is positioned at the central authorities at upper mold top, and gas outlet arranges around sprue gate even circumferential.
Preferably, sprue gate is the pyramidal structure that internal diameter is sequentially reduced from top to bottom.
Preferably, upper mold is further opened with cold air road, and the centrage in upper cold air road is the most equal with the distance of boss surface, from
And uniformly cool down upper mold；Lower mold is further opened with lower cold air road, and the centrage in lower cold air road is the most equal with the distance of recess surface, from
And uniformly cool down lower mold；Upper cold air road is all connected with cold air source with lower cold air road.
Preferably, sprue gate is additionally provided with foam ceramic filter.
The invention have the benefit that
1. mould is itself divided into two parts, can change the size of die cavity thus for casting by the control of motion
The first type part of different-thickness；Additionally pass through in upper mold, set out air flue and gas outlet to be discharged by the air in die cavity thus anti-
The most just there is bubble in type part, improve the quality of just type part.
2. gas off-take is pyramidal structure, and big top and small bottom, thus makes the partial melting metal entering gas off-take hold
Continuous rise during gradually cooled thus gas off-take is blocked, it is to avoid motlten metal is right to outward leakage from gas off-take
Staff on the scene causes physiological damage, and the gas off-take of this pyramidal structure is also beneficial to the demoulding.
3. upper die and lower die all offer cold air road, and different cold air roads and the distance between corresponding recess and protuberance
The most equal, thus the quality of type part at the beginning of making motlten metal to be cooled down uniformly thus ensureing.
Accompanying drawing explanation
Fig. 1 is the sectional view of released state of the present invention；
Fig. 2 is the sectional view of buckling state of the present invention；
Fig. 3 is the sectional view of casting condition of the present invention.
Reference:
1 upper mold；1.1 sprue gate；1.2 running channel；1.3 protuberance；Cold air road on 1.4；1.5 gas off-take；2 lower molds；2.1 recess；
2.2 times cold air roads；3 fixing structures；4 die cavities；5 foam ceramic filters；6 first type parts.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating the present invention
Technical scheme, and can not limit the scope of the invention with this.
As shown in Figures 1 to 3, the parison mold mould of a kind of precast, it is used for casting bowl-shape just type part 6, including alloy material
Upper mold 1 and lower mold 2.The bottom of upper mold 1 has a protuberance 1.3 matched with the inner surface of first type part 6, the top of lower mold 2
Portion has a recess 2.1 matched with the outer surface of first type part 6；Upper mold 1 and lower mold 2 are closely fastened by fixing structure 3,
When both fasten, between protuberance 1.3 and recess 2.1, form die cavity 4.The top of upper mold 1 offers sprue gate 1.1 and some respectively
Gas outlet, sprue gate 1.1 is positioned at the central authorities at upper mold 1 top, and gas outlet arranges around sprue gate 1.1 even circumferential.Sprue gate 1.1
Being connected with die cavity 4 by running channel 1.2, gas outlet is connected with the top of die cavity 4 by gas off-take 1.5.
The pyramidal structure that sprue gate 1.1 is sequentially reduced from top to bottom for internal diameter, is additionally provided with ceramic filter in sprue gate 1.1
Net 5；The pyramidal structure that gas off-take 1.5 is sequentially reduced from bottom to top for internal diameter.Toppling over of motlten metal is easy at sprue gate 1.1, and
There is enough space mounting foam ceramic filters 5.The pyramidal structure of gas off-take 1.5 be not only beneficial to enter motlten metal therein and
Time cooling blocked thus prevent motlten metal from leaking and endanger the health of staff, and the beneficially demoulding.
Upper mold 1 is further opened with cold air road 1.4, and the centrage in upper cold air road 1.4 is homogeneous with the distance on protuberance 1.3 surface
Deng, thus uniformly cooling upper mold 1；Lower mold 2 is further opened with lower cold air road 2.2, the centrage in lower cold air road 2.2 and recess 2.1 table
The distance in face is the most equal, thus uniformly cooling lower mold 2；Upper cold air road 1.4 is all connected with cold air source with lower cold air road 2.2.Two
Cold air road can uniformly cool down upper and lower mould 2 thus uniformly cooling just type part 6 is to reach qualified quality.
After the demoulding, the burr on first type part, the burr being cooled into such as motlten metal in gas off-take and running channel, can pass through
Electric mill is removed.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
