Abstract

The utility model relates to a profile-followed chaplet for fixing a sand core, which belongs to the technical field of casting and has the technical scheme that: the profile-followed chaplet is made of thin metal sheets with different sizes, is slightly bossed in the middle, and has a certain strength and elasticity; the materials used by the profile-followed chaplet are the same as casting materials; the melting point of the profile-followed chaplet is slightly higher that the melting point of a metal to be cast; and the surface of the profile-followed chaplet is clean without oil, rust and steam. The profile-followed chaplet for fixing the sand core has the beneficial effects that: the difficulty in a casting process of a product is simplified, the complexity grade of the process of the product is reduced, the accuracy in size and profile position of the product is improved, particularly great superiority is provided for a box body with complicated inner cavity and shell type product casting, the problems of core breaking, floating and the like of the products are solved, the yield of the products is improved, the production efficiency of the products is improved, the production cost is reduced, and the market competitiveness of the products is improved.

Description

A kind of fixedly core is used the conformal stud

Technical field

The utility model relates to a kind of fixedly core and uses the conformal stud, belongs to casting technology field.

Background technology

At present, in foundry engieering, using the supporter of special shape is that core is carried out supplemental support is a kind of general practice to stud.The shape of stud is varied, the plane, circular arc, ∏ shape or the like, size is different in size, select shape, the size of stud according to the position of stud in foundry goods, the shape of die cavity, the wall thickness of foundry goods.But many for core assembly, compartment is many, the complicated cavity product of disconnected chamber, disconnected outstanding core and wall thickness dimension, the strict product of the accuracy of form and position; Just need design and produce many different, studs that size is different; Each stud also will measure its required height with walk; Workload is quite big, becomes an outstanding weak link that influences moulding, following core efficient.Therefore, be badly in need of a kind of broad-spectrum fixedly core of innovation and use the conformal stud.

Summary of the invention

The purpose of the utility model overcomes above defective exactly, develops a kind of fixedly core and uses the conformal stud

The technical scheme of the utility model is: the conformal stud is processed with the different foil of size; Middle slightly microprotrusion has certain intensity and elasticity, and material therefor is identical with casting material; The fusing point of a little higher than casting metal of its fusing point, surface clean, oily, rustless, the no aqueous vapor of nothing.

The beneficial effect of the utility model is: simplified product the casting technique difficulty, reduced the complex process class of product, improved the product size precision and the accuracy of form and position, especially have more superiority for inner chamber complicated casing and housing series products foundry goods; Solve problems such as the folding core of this series products, the core that wafts, improved the yield rate of this series products; Improve production efficient, reduced production cost, improved the competitiveness of product in market.

The specific embodiment

Specify the details and the working condition of the utility model in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4.The different foil of conformal stud 1 usefulness size is processed, and middle slightly microprotrusion has certain intensity and elasticity; Material therefor is identical with casting material, and ironcasting is processed with mild steel, and cast copper and aluminum casting are processed with fine copper and fine aluminium respectively; The fusing point of a little higher than casting metal of its fusing point; To guarantee that conformal stud 1 does not have enough strength support cores before foundry goods solidifies fully, in process of setting, fuse surface clean, oily, rustless, the no aqueous vapor of nothing simultaneously well with foundry goods; Preferably zinc-plated or zinc-plated, want strict pickling before electroplating.During use, the number of conformal stud 1 will rationally be confirmed, makes it have enough Area of bearing.When being applied to whole outstanding core situation, conformal stud 1 will descend between integral sand core 2 and the outstanding core position 3 of core; When being applied to make up outstanding core situation, conformal stud 1 will descend between cover core 4 and the outstanding core 5 of middle pressure, and can not descend between outstanding core 5 of middle pressure and end core 6.The beneficial effect of the utility model is: simplified product the casting technique difficulty, reduced the complex process class of product, improved the product size precision and the accuracy of form and position, especially have more superiority for inner chamber complicated casing and housing series products foundry goods; Solve problems such as the folding core of this series products, the core that wafts, improved the yield rate of this series products; Improve production efficient, reduced production cost, improved the competitiveness of product in market.

Claims

One kind fixedly core use the conformal stud; It is characterized in that: conformal stud (1) is processed with the different foil of size; Middle slightly microprotrusion has certain intensity and elasticity, and material therefor is identical with casting material; The fusing point of a little higher than casting metal of its fusing point, surface clean, oily, rustless, the no aqueous vapor of nothing.
