A kind of die casting
Technical field
The utility model relates to mould, relates in particular to a kind of mould of producing the pattern complexity, dividing mould linking requirement height, the thin alloy of hollow wall.
Background technology
The value of alloy handicraft is good looking appearance, so manufacturer needs the constantly product of the new profile of design.And the existing mould of producing alloy handicraft, a mold can only be produced a kind of product of profile.Along with the eliminating of product, mould has also just lost value, causes huge waste like this.
And the pattern of alloy handicraft is very complicated usually, causes the branch mould of mould complicated, is easy to generate that the branch mould is connected bad and that folder is made a slip of the tongue is big, causes the back processing difficulties.
And alloy handicraft is generally the product of hollow, thin-walled, so die sinking is difficult to find impetus, puts forth effort inequality when ejecting, and causes the product distortion.
The utility model content
The utility model provides a kind of die casting at the above-mentioned defective of prior art, with brand-new structure, makes mould have shared property, thereby cuts the waste.
Further, the utility model distributes rationally the branch mould, solves the problem of product easy deformation when dividing the problem that is connected bad between the mould and die sinking to eject.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of die casting is characterized in that: comprise mould, slide block, core rod in external mold, the mould, mould is embedded in the external mold in the described mould; Slide block is provided with guide rail, can be in mould the guiding lower slider of mould; Core rod is arranged in mould mould central authorities, forms die cavity jointly with slide block.
Preferably, described slide block is at least two, and the contact-making surface of mould and horizontal plane acutangulate in slide block and the mould.
Preferably, described slide block is four, contact-making surface and slide block degree at 45 angle between the slide block.
Preferably, the contact-making surface of mould and horizontal plane angle are 70 ° in described slide block and the mould.
As can be seen from the above technical solutions, the utility model is made up of mould, slide block, core rod in external mold, the mould, for the little profile variation of product, only needing to change slide block gets final product, and mould can be used in external mold and the mould, the product that bigger variation is arranged for product size also only needs more mould and slide block in the die change, and can shared external mold, has saved huge cost in actual production.Further, the utility model slide block is divided into four, degree at 45 angle is distributed in the die cavity of mould sealing in the mould between slide block and the slide block, oblique formula can solve because of thermal expansion problem causes die parting line and be connected bad problem, slide block is provided with guide rail, its stability, the slip smoothness is very good, also is that other type structure mould is unrivaled; The contact-making surface of mould and horizontal plane angle are 70 ° in the utility model slide block and the mould, and slide block simultaneously upwards and outwards withdraw from, is held out product under the effect of push rod, and the impetus that ejects is an entire product, the situation of product distortion can not occur.

The specific embodiment
Below in conjunction with the specific embodiment the utility model is described in further detail.
With reference to shown in Figure 1, the utility model comprises mould 2 in external mold 1, the mould, slide block 3, core rod 4, in the mould mould 2 embed with external mold 1 in; During slide block 3 was arranged in the die cavity of 2 sealings of mould in the mould, slide block 3 was provided with guide rail, can be in mould the guiding lower slider of mould 2; Core rod 4 places mould mould 2 central authorities, constitutes die cavity jointly with each slide block, and contact-making surface between the slide block and slide block degree at 45 angle.In process of production, if the product design change in size is bigger, only need more mould, slide block, core rod in the die change, and external mold 1 and the guide pillar 5 that is located on the external mold can be shared, the mould of an existing relatively mould one usefulness has been saved wide variety of materials, reduces production costs; And be that profile slightly changes for product, then only need to change slide block and core rod gets final product, saved these two parts of mould in external mold and the mould especially.
Referring to shown in Figure 2, mould 2, slide block 3, core rod 4 all place on the supporting plate 12 in the mould, and thimble 11 is installed on the ejector retainner plate 10, and thimble 11 penetrates supporting plate 12 and touches mutually with slide block.The contact-making surface of mould 2 becomes 20 ° of angles in slide block 3 and the mould with vertical plane, promptly become 70 ° of angles with horizontal plane, during die sinking, under the motion of ejector retainner plate, drive thimble bump slide block 3, the contact-making surface of mould 2 is obliquely upward to withdrawing from the guiding lower edge slide block 3 of four slide blocks mould 2 in mould and the mould, whole finished product is held out, the demoulding easily, and be unlikely to put forth effort uneven with the finished product face damage.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
