Description
Technical field
This utility model relates to a kind of mould, particularly relates to a kind of investment casting mold be easy to and loose core.
Background technology
Model casting typically refers to fusible material is made apperance, makes shell at apperance Surface coating refractory material, then
Apperance is discharged shell, thus obtains the founding method of the casting mold without die joint.Due to the widely used wax material system of apperance
Make, therefore often model casting is referred to as " lost-wax casting ".First operation that model casting produces manufactures fusible pattern exactly, and fusible pattern is to use
Form the model in the medium-sized chamber of fire-resistant shell.Production use mostly pressure the method manufacture of pasty state mould material press-in die is melted
Mould, needs when fusible pattern is complex-shaped to arrange die cavity on core, for preventing core during loosing core from interfering with fusible pattern, needs
Combinatory core to be used, during work, first extracts the mid portion of combinatory core, then extracts its remaining part of combinatory core
Point.But actual production process finding, this combinatory core, during loosing core, is extracted out after mid portion, the core on upper strata
Directly fall downward stratotype core, easily damages apperance, and this combinatory core to there is also deadweight excessive, location difficulty is not
Foot.
Utility model content
The purpose of this utility model be for the deficiencies in the prior art in place of, overcome during combinatory core is loosed core hold
The problem of easy damaged apperance, it is provided that a kind of investment casting mold.
A kind of investment casting mold, including mold and lower mold, also includes the first core and the second core, the first core
And second core be arranged between mold and lower mold, the first core and the second core are connected to by scissor lever
Together, the first free portion of scissor lever and the second free portion turn around the rotary shaft of scissor lever is relative
Dynamic, make the distance between the first standing part of scissor lever and the second standing part change；Described scissor
First standing part of intersection lever is fixed on the first core, and the second standing part is fixed on the second core, and first freely
It is provided with support bar between part and the second free portion, described support bar is provided with nut, rotate nut and make first certainly
Relatively rotated by between part and the second free portion.
As preferably, the first end of described support bar is fixed in the first free portion, and the second end is through second certainly
By the through hole in part, described nut is arranged on the second end, is positioned at below through hole, and described the second end is provided with and spiral shell
Female screw thread coordinated.
As preferably, for removably connecting between first end and first free portion of described support bar.
As preferably, described nut is wing nut.
The beneficial effects of the utility model: this utility model utilizes scissor lever and support bar to control the first core
And second distance in space between core, when loosing core, rotating that nut makes can between the first free portion and the second free portion
To relatively rotate, under the first core self gravitation effect, the first standing part and the second standing part move closer to, so that
First core and the second core can overall be extracted out, it is to avoid during loosing core, core influences each other thus damages apperance, improves
The quality of apperance, and improve efficiency of loosing core；This utility model reduces the deadweight of core, and combinatory core is positioned
The simplest, reduce die cost.
Accompanying drawing explanation
For clearer explanation the technical solution of the utility model, required use in embodiment being described below
Accompanying drawing is briefly described, it should be apparent that, drawings discussed below is only embodiments more of the present utility model, for this
From the point of view of the those of ordinary skill in field, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing.
Fig. 1 is the isometric view of investment casting mold.
Fig. 2 is the first core and the isometric view of the second core.
Fig. 3 is the left view schematic diagram of the first core and the second core.
Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is clearly and completely illustrated.
Embodiment
Fig. 1 be the isometric view of investment casting mold, Fig. 2 be the isometric signal of the first core and the second core
Figure, Fig. 3 are the left view schematic diagram of the first core and the second core, provide a kind of investment casting mold in the present embodiment.
As shown in Figure 1 and Figure 2, a kind of investment casting mold, including mold 1 and lower mold 2, also include the first core 3 He
Second core 4, the first core 3 and the second core 4 be arranged between mold 1 and lower mold 2, the first core 3 and the second core 4
Linked together by scissor lever 5, the first free portion 51 and the second free portion 52 of scissor lever 5
Rotary shaft 53 around scissor lever 5 relatively rotates, and the first standing part 54 and second making scissor lever 5 is solid
The distance determined between part 55 changes；First standing part 54 of described scissor lever 5 is fixed on the first core 3
On, the second standing part 55 is fixed on the second core 4, is provided with and props up between the first free portion 51 and the second free portion 52
Strut 6, described support bar 6 is provided with nut 61, rotates nut 61 and makes the first free portion 51 and the second free portion 52
Between relatively rotate.
As it is shown on figure 3, the first end 62 of described support bar 6 is fixed in the first free portion 51, the second end 63 is worn
Crossing the through hole 56 in the second free portion 52, described nut 61 is arranged on the second end 63, is positioned at below through hole 56, and described
It is provided with, on two ends 63, the screw thread coordinated with nut 61；The first end 62 of described support bar 6 and the first free portion 51 it
Between for removably connecting；Described nut 61 is wing nut；What deserves to be explained is: the upper surface and second of described first core 3
The lower surface of core 4 is provided with the die cavity coordinated with mould.
When loosing core, rotating the wing nut on support bar, making can phase between the first free portion and the second free portion
To rotation, under the first core self gravitation effect, the first core and the second core move closer to, and treat the first core and Second-Type
After core laminating, the first core and the second core one are extracted out.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in
Change or replacement, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is as the criterion with the protection domain of claims.
