Abstract
The utility model relates to a special cold iron sand core, which comprises a sand core body. The sand core body comprises a peripheral surface and support core heads which are arranged at the two ends of the peripheral surface; a sand core cavity is formed by the support core heads and the peripheral surface of the sand core body and is provided with an open end; a recessed plane is formed at the open end of the sand core cavity; an exhaust hole is formed in the recessed plane, and is communicated with the sand core cavity; the peripheral surface of the sand core body and the two support core heads are molded integrally. By the sand core, the operation time for making a sand core by filling gaps with multiple pieces of cold iron and molding sand in a matched manner in the prior art is shortened, the using amount of raw materials and auxiliary materials such as molding sand, resin and a curing agent is reduced, the defects of hole shrinkage, looseness, air holes and the like formed inside products are overcome and reduced, and the workload of subsequent cleaning and grinding of the products is reduced, thereby reducing the production cost and increasing the production efficiency.
Description
Technical field
The utility model relates to castings production field, the special chill core in especially a kind of thermoelectricity air inlet class parts of Casting production.
Background technology
In castings production, can use at core, form by core the position that inner chamber, hole and the foundry goods profile of foundry goods can not be shaked out, in order to obtain qualified foundry goods, core must have enough strength and stiffness; Outside the timely discharge type of gas energy that in the process forming at foundry goods, core produces; When foundry goods shrinks, resistance is little, easily sand removal.In thermoelectricity air inlet class parts of Casting is produced, because of product operating characteristic, require all very high to interiors of products and surface quality, very strict, in the time producing, must use chill, conventional production is all the polylith chill differing in size according to product structure design, be arranged in die surface, centre reserves certain interval, fill and the core made with molding sand, in the time arranging chill, to spend a large amount of labor hours like this, chill gap is due to the bad plug of sand, while smashing not consolidation, follow-up work meeting is produced to very large difficulty, during as matched moulds, want stop-off mould, or repair and move with coating reinforcement etc., because chill is put bad, to product, follow-up polishing work also increases very large workload, between the bad or chill of chill management and control, sand is not smash consolidation and can be had a huge impact product quality yet, the serious product rejection that causes, therefore product is all great, from several tons to tens tons, can bring very large loss to production company.This special chill core of ad hoc meter for this reason.
Utility model content
The purpose of this utility model is in order to solve the existing defect of core in the production of thermoelectricity air inlet class parts of Casting in prior art, provide a kind of and reduce the coremaking operation time, the supplementary material consumptions such as energy-saving sand, resin and curing agent, avoid and reduce interiors of products and produce the special chill core of the defects such as shrinkage cavity, loose and pore.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of special chill core, comprises core body, and described core body comprises a side face and is arranged on the support core print at described side face two ends, the side face formation core cavity of this support core print and described core body, and this core cavity has an openend;
The open end of described core cavity is provided with a recessed plane, in this recessed plane, is provided with exhaust outlet, and this exhaust outlet is communicated with described core cavity; The side face of core body and two supporting-cores are first body formed.
The special chill core of above-mentioned one, is provided with the circumferential reinforcement that extends along described core body side face and from radial reinforced rib that described in the interior side direction of described core body side face, recessed plane is extended in described core cavity.
The special chill core of above-mentioned one, the openend of described core cavity is surrounded by two cross sections and described two sides of supporting core print of described core body side face, and two cross sections of core body side face coordinate with profile on external mold.
The special chill core of above-mentioned one, is equipped with hole for hoist on described two support core prints.
The special chill core of above-mentioned one, the material of described core body is chill material.
The beneficial effects of the utility model are: the side face of this chill core and two supporting-cores are first body formed, have overcome traditional to coordinate molding sand to fill and the existing interiors of products of core made produces the defect of shrinkage cavity, loose and pore by polylith chill; Outside the timely discharge type of gas that the exhaust outlet that recessed plane is provided with can produce core in time; After foundry goods moulding, carrying out fixture while getting core, owing to being by pneumatic or electronic clamp core, use other power lifting core, at two holes for hoist that support to be provided with on core prints, lifting is got to core and played effect easily; Reduce the coremaking operation time, the supplementary material consumptions such as energy-saving sand, resin and curing agent, avoid and reduce interiors of products producing the defects such as shrinkage cavity, loose and pore, reduce the workload of the follow-up cleaning polishing of product, thereby reduce production costs, and enhance productivity.
Brief description of the drawings
Fig. 1 is front schematic view of the present utility model;
Fig. 2 is the schematic diagram of the utility model reverse side.
Detailed description of the invention
For making that architectural feature of the present utility model and effect of reaching are had and further understand and be familiar with, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As shown in Figure 1 and Figure 2, a kind of special chill core, comprise core body 1, the material of core body is preferably chill, core body 1 comprises a side face 2 and is arranged on the support core print 3 at side face 2 two ends, this support core print 3 forms core cavity 4 with the side face 2 of core body, and this core cavity 4 has an openend;
The open end of core cavity 4 is provided with a recessed plane 5, in this recessed plane 5, is provided with exhaust outlet 6, and this exhaust outlet 6 is communicated with core cavity 4; The side face 2 of core body and two support core prints 3 are one-body molded.
In order to strengthen the Rigidity and strength of core, in core cavity 4, be provided with the circumferential reinforcement 7 extending along core body side face 2 and the radial reinforced rib 8 extending from the recessed plane 5 of interior side direction of core body side face 2.
Further improve as the utility model, the openend of core cavity 4 is surrounded by the cross section 21 of core body side face 2 and the sides of cross section 22 and two support core prints, and two cross sections 21 and 22 of core body side face coordinate with profile on external mold; On two support core prints 3, be equipped with hole for hoist 31.
It is one-body molded that the side face 2 of this chill core and two support core prints 3, overcome traditional to coordinate molding sand to fill gap and the existing interiors of products of core made produces the defect of shrinkage cavity, loose and pore by polylith chill; Outside the timely discharge type of gas that the exhaust outlet 6 that recessed plane 5 is provided with can produce core in time; After foundry goods moulding, carrying out fixture while getting core, owing to being by pneumatic or electronic clamp core, use other power lifting core, at two holes for hoist 31 that support to be provided with on core prints 3, lifting is got to core and played effect easily; This core has reduced tradition and has coordinated molding sand to fill gap and the coremaking operation time of the core made by polylith chill, the supplementary material consumptions such as energy-saving sand, resin and curing agent, avoid and reduce interiors of products producing the defects such as shrinkage cavity, loose and pore, reduce the workload of the follow-up cleaning polishing of product, thereby reduce production costs, enhance productivity.
