Description
Technical field
The utility model relates to the mould of foundry goods core, relates in particular to a kind of block structure of taking out of turbine case runner core box, belongs to the machine casting field.
Background technology
As shown in Figure 1, be existing turbine case runner core box structure, comprise: a whole set of core box 6 that dynamic model 1 and quiet mould 2 constitute, be provided with two snail hull shape core cavitys arranged side by side and corresponding mutually in dynamic model 1 and the quiet mould 2, that is: left half core cavity 3, right half core cavity 4, the top of a left side half core cavity 3 and right half core cavity 4 respectively is provided with the core that is connected with the core cavity and penetrates sand mouth 5, and dynamic model 1 and quiet mould 2 mutual correspondences snap together and constitute an one-piece core box 6.
When making core, above-mentioned this core box structure is with snail hull shape core in two, get core after, stick together again, repair die joint then.Because these work all are by manually carrying out, be difficult to guarantee uniformity bonding, finishing, the visual position that can't see of core cavity is difficult to obtain cleaning, makes the turbine case core cavity easily produce fash, and inner chamber has fash turbine case foundry goods, can only become waste product.Thereby caused man power and material's waste, increased production cost.Simultaneously, make the qualification rate of product descend.If accidentally inner chamber there is fash turbine case foundry goods to be assembled on the automobile, will cause turbocharger to stop up the serious consequence that automobile is called back.
In order to address the above problem, in dynamic model and quiet mould, two snail hull shape core cavity core boxes beating in two are modified into a cover integral turbine shell core box structure, two corresponding mutually middle parts that respectively are arranged on dynamic model and quiet mould of snail hull shape core cavity, the top of core cavity respectively is provided with the core that is connected with the core cavity and penetrates Sha Kou, and dynamic model and the mutual correspondence of quiet mould snap together the back and constitute an one-piece core box.This core box structure can be produced the integral sand core one-shot forming naturally, has avoided because snail hull shape Niu Xin is made in two, get core after, the core cavity that bonding by manually carrying out again, finishing etc. caused produces the fash problem.But because turbine case core cavity flow passage structure is a groove structure, this eddy current road lumen channels directly can not play core, therefore, still remains to be improved.
The utility model content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of block structure of taking out of turbine case runner core box is provided, and it can be installed in the integral turbine shell core box, when ejecting core, together ejects together with taking out block structure; Extract the loose piece assembled mold out, extract loose piece again out and be installed in loose piece on the loose piece assembled mold, then, directly trip out core, core is just produced naturally by one-shot forming, thereby, improved qualification rate and the product quality of snail hull shape Niu Xin; Simultaneously, improve production efficiency, reduced cost.
The purpose of this utility model is realized by following technical scheme.
A kind of turbine case runner core box take out block structure, it is characterized in that: comprising: the loose piece assembled mold, place several loose pieces on the loose piece assembled mold, wherein,
The loose piece assembled mold is provided with a chassis, is provided with several holes below this chassis, is provided with and is fixed with a steady pin in several holes respectively; The top on chassis is provided with a central shaft, is provided with several alignment pins around keeping at a certain distance away above the chassis of mold central shaft;
Be respectively equipped with the dowel hole that matches with several alignment pins above the chassis on several loose pieces, several loose pieces are around loose piece assembled mold central shaft, and be installed on the alignment pin on the chassis by the dowel hole on the loose piece, several loose pieces after the assembling constitute a whole piece of taking out for the hodmadod shape with the loose piece assembled mold.
Hole below described steady pin and the chassis is a tight fit.
Dowel hole on described several loose pieces and several alignment pins on the chassis are for movingly.
The middle part of described central shaft is provided with an axis hole.
Described chassis is discoid.
The beneficial effects of the utility model: the utility model can be installed in the integral turbine shell core box, when ejecting core, together ejects together with taking out block structure; Extract the loose piece assembled mold out, extract loose piece again out and be installed in loose piece on the loose piece assembled mold, then, directly trip out core, core is just produced naturally by one-shot forming.Thereby, improved qualification rate and the product quality of snail hull shape Niu Xin; Simultaneously, improve production efficiency, reduced cost.
