Description

A kind of casting mould assembling improvement structure

Technical field

The utility model relates to die casting technical fields, and in particular to a kind of casting mould assembling improvement structure.

Background technique

In the prior art, casting mould upper casing sand core and lower casing sand core generally use viscose glue and are screwed during mould assembling Mode come guarantee cast quality.One, design has adhesive glassine tank in lower casing sand core, and viscose is placed in adhesive glassine tank, and glue is solid after molding Change clings；Two, sand core is locked using self-tapping screw between upper casing sand core and lower casing sand core, but actual production process by The case where will appear failure mode during adhesive curing is bad and screw locking when productive temp is fast, cause to rise when casting Phenomena such as case, runout, causes casting to be scrapped, and self-tapping screw haves the defects that the rate of recovery is low low with the service life.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of casting mould assembling improvement structure, solves above-mentioned Technical problem.

In order to solve the above technical problems, the technical scheme adopted by the utility model is:

A kind of casting mould assembling improvement structure, including upper casing sand core and lower casing sand core, the upper casing sand core and the lower casing sand Case card slot is formed at the molding of core, case card is connected in the case card slot, the shape of the case card is similar to I-shaped, described The material of case card is steel alloy.

Further, the case card is equipped with pattern draft, and the pattern draft is 4 °.

Further, the case card is equipped with gradient.

Further, the number of the case card slot is 6.

Further, the shape of the end face of the case card is similar to " trapezoidal ".

Compared with prior art, the beneficial effects of the utility model are as follows:

The utility model provides a kind of casting mould assembling improvement structure, substitutes the prior art by clamping case card at case card slot In self-tapping screw mould assembling is locked, avoid screw failure mode, be easy to appear the case that rises, artillery fire phenomenon, and case card Manufacturing cost it is lower, the larger easy recycling of volume, deflection small service life is high.It is easy to use.

Specific embodiment

The utility model in order to better understand is further fairly set out in the utility model below with reference to embodiment Hold, but the protection content of the utility model is not limited solely to the following examples.In the following description, a large amount of tools are given The details of body more thoroughly understands in order to provide to the utility model.However, aobvious and easy to those skilled in the art See, the utility model may not need one or more of these details and be carried out.

As shown in Figure 1 and Figure 2, in the prior art, upper casing sand core 1 and lower casing sand core 2, upper casing sand core 1 are covered in lower casing sand core 2 On molded, in which: adhesive glassine tank 3 is equipped in lower casing sand core 2.

Embodiment

In the application, a kind of casting mould assembling improvement structure, including upper casing sand core and lower casing sand core, in which: 1 He of upper casing sand core The prior art is identical, and adhesive glassine tank 3 is not contained in lower casing sand core 2.

As shown in Figure 3, Figure 4, case card slot 4, the case card are formed at the molding of the upper casing sand core and the lower casing sand core The number of slot 4 is 6, and case card 5 is connected in the case card slot 4, and the case card 5 is connected in the case card slot 4 by manual, To locking at the molding of upper casing sand core and lower casing sand core, the material of the case card 5 is steel alloy, and manufacturing cost is lower, body The larger easy recycling of product, deflection are small.

As shown in Figure 5, Figure 6, the shape of the case card 5 is similar to I-shaped, and the end surface shape of the I-shaped is Similar to " trapezoidal ", the case card 5 is equipped with pattern draft 6, and the pattern draft is 4 °, is convenient for the sand mold in casting mould It can be good at demoulding.In addition, the case card is equipped with gradient 7, play the role of being that under external force, case card can be by shell Card is increasingly tighter at the molding of sand core and lower casing sand core.

Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, this field Other modifications or equivalent replacement that those of ordinary skill makes the technical solution of the utility model, it is practical without departing from this The spirit and scope of new technique scheme should all cover in the scope of the claims of the utility model.

The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, for this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
