Abstract
This utility model relates to a kind of combinatory core, including the first core (1) and the second core (2), first core (1) and the second core (2) are linked together by scissor lever (3), and the first free portion (31) and the second free portion (32) rotary shaft (33) around scissor lever (3) of scissor lever (3) relatively rotate；First standing part (34) of described scissor lever (3) is fixed on the first core (1), second standing part (35) is fixed on the second core (2), is provided with spring (4) between the first free portion (31) and the second free portion (32).This utility model solves the problem easily damaging fusible pattern during combinatory core is loosed core, and improves loose core efficiency and fusible pattern quality, it is provided that a kind of combinatory core.
Description
Technical field
This utility model relates to mould applications, particularly relates to the combinatory core of a kind of investment casting mold.
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 fusible pattern, 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 fusible pattern, it is provided that a kind of combinatory core.
A kind of combinatory core, including the first core and the second core, the first core and the second core by scissor friendship
Fork lever links together, and the first free portion of scissor lever and the second free portion are around scissor lever
Rotary shaft relatively rotates, and makes the distance between the first standing part of scissor lever and the second standing part become
Change；First standing part of described scissor lever is fixed on the first core, and the second standing part is fixed on Second-Type
On core, being provided with spring between the first free portion and the second free portion, described spring supporting is at scissor lever
Between first free portion and the second free portion so that form space between the first core and the second core.
As preferably, described spring one end is fixed in the first free portion, and the other end is fixed in the second free portion.
As preferably, for removably connecting between described spring and scissor lever.
As preferably, described spring is torsionspring.
The beneficial effects of the utility model: this utility model utilize scissor lever and spring control the first core and
The distance in space between second core, when loosing core, compresses the distance between the first free portion and the second free portion the most adjustable
Distance between whole first standing part and the second standing part, thus progressively adjust space between the first core and the second core
Size, make the first core and the second core can overall extraction out and the quality of fusible pattern will not be improve with damage fusible pattern, and can
Improve efficiency of loosing core；This utility model reduces the deadweight of core, and makes combinatory core location the simplest, reduces
Mould holistic 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 combinatory core.
Fig. 2 is the left view schematic diagram of combinatory 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 combinatory core, Fig. 2 be the left view schematic diagram combinatory core of combinatory core
Left view schematic diagram.As shown in Figure 1 and Figure 2, the present embodiment provides a kind of combinatory core.
A kind of combinatory core, including the first core 1 and the second core 2, the first core 1 and the second core 2 pass through shears
Formula intersection lever 3 links together, and the first free portion 31 of scissor lever 3 and the second free portion 32 are around scissor
The rotary shaft 33 of intersection lever 3 relatively rotates, and makes the first standing part 34 and the second standing part 35 of scissor lever 3
Between distance change；First standing part 34 of described scissor lever 3 is fixed on the first core 1, and second
Standing part 35 is fixed on the second core 2, is provided with spring 4, institute between the first free portion 31 and the second free portion 32
State between the first free portion 31 and the second free portion 32 that spring 4 is supported on scissor lever 3 so that the first core
1 and second forms space between core 2.
Described spring 4 one end is fixed in the first free portion 31, and the other end is fixed in the second free portion 32；Described
For removably connecting between spring 4 and scissor lever 3；Described spring 4 is torsionspring, what deserves to be explained is: described
The upper surface of the first core 1 and the lower surface of the second core 2 are provided with the die cavity coordinated with mould.
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.
