Abstract
The invention relates to a gas engine rack die, in particular to a main core box of a gas engine rack die, characterized in that the main core box for a gas engine rack die is formed by mutually buckling a moving die and a stationary die, wherein the middle of the moving die and the middle of the stationary die are respectively provided with a moving die sand core cavity and a stationary die sand core cavity which mutually correspond; two sides of the bottom of the moving die sand core cavity are respectively fixed with one locating block; two sides of the stationary die sand core cavity are respectively provided with a slideway; the slideways on two sides are respectively matched with a slide block provided with a screw hole; two sides of the stationary die are respectively fixed with a fixed baffle provided with a through hole through which one bolt passes; and the bolt is matched with the screw hole arranged on the slide block. The invention has the advantages of peculiar structure, high manufacture efficiency, high precision and being easy for operation, prolongs the service life of the die, improves die size precision and satisfies volume production.
Description
Technical field
The present invention relates to a kind of gas engine frame mould, especially relate to a kind of main core box of gas engine frame mould.
Background technology
The gas engine frame needs high-tech, highly difficult foundry goods, it has complicated inner-cavity structure, present main core box structure heaviness, difficult, thin water jacket core box easy deformation, back-up sand, consolidation inconvenience are torn the core complicated operation open, long period of operation makes the core box distortion easily, is difficult to satisfy high-quality, frame castings exploitation efficiently and batch process.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of structure uniqueness be provided, produce the efficient height, the precision height, easy to operate, increased die life,, improved the die size precision, satisfied the main core box of a kind of gas engine frame mould of producing in batches.
The present invention realizes in the following way:
A kind of main core box of gas engine frame mould, it is characterized in that: it is to be formed by dynamic model and corresponding mutually fastening of quiet mould, the middle part of this dynamic model and quiet mould is respectively equipped with two corresponding mutually dynamic model core cavity and quiet sand core cavitys, at each fixing a positioning block of the two bottom sides of dynamic model core cavity, both sides at quiet sand core cavity respectively are provided with a slideway, respectively are combined with a slide block that has a screw on the slideway of both sides; The both sides of quiet mould respectively are fixed with a fixed dam that is provided with through hole, pass a bolt in the through hole of fixed dam respectively, and this bolt is combined together with the screw that is located on the above-mentioned slide block;
On the described bolt spring is installed;
Between described slide block and the slideway for movingly.
1) structure uniqueness: the detachable that main core box provided by the invention changes is in the past split core box, design core box structure is two parts: comprise dynamic model and quiet mould, the middle part of this dynamic model and quiet mould is provided with two corresponding mutually inner chamber core cavitys, each is provided with and fixing a positioning block in the bottom of dynamic model core cavity, both sides at quiet sand core cavity respectively are provided with a slideway, one slide block respectively is installed on the slideway, between slide block and the slideway for movingly; The both sides of quiet mould respectively are fixed with a fixed dam, pass a bolt in the through hole of both sides fixed dam respectively, and this bolt links together with the screw that is located on the slide block, and spring respectively is installed on the bolt; Dynamic model and the mutual correspondence of quiet mould snap together and constitute an one-piece core box.The present invention makes the integral sand core one-shot forming, has reduced production cost, has improved product quality and production efficiency.
2) implement simple and easy, simple for production, easy to operate, prolongation die life: the core box of splitting provided by the invention has effectively guaranteed the sand mold dimensional accuracy, has simplified the core box structure, is convenient to the back-up sand consolidation.The water jacket core box structure of novelty has been guaranteed the simplification production of elongated thin jacket core, has guaranteed fast, high-quality, the exploitation and the batch process of frame castings efficiently.The casting dimension qualification rate improves 51% than like product.
3) core box structure provided by the invention has been guaranteed the simplification production of elongated thin jacket core.Stop the sand mold distortion, solved the puzzlement that scale error appears in elongated core box long-term production.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of main core box of gas engine frame mould, as shown in Figure 1: it is to be formed by dynamic model 1 and corresponding mutually fastening of quiet mould 2, the middle part of this dynamic model 1 and quiet mould 2 is respectively equipped with two corresponding mutually dynamic model core cavity 3 and quiet sand core cavitys 4, at each fixing a positioning block of the two bottom sides of dynamic model core cavity 3, respectively be provided with a slideway 6 in the both sides of quiet sand core cavity 4, respectively be combined with a slide block 7 that has a screw on the slideway 6 of both sides; The both sides of quiet mould 2 respectively are fixed with a fixed dam 8 that is provided with through hole, pass a bolt 9 in the through hole of fixed dam 8 respectively, and this bolt 9 is combined together with the screw that is located on the above-mentioned slide block 7.
On the described bolt 9 spring is installed.
Between described slide block 7 and the slideway 6 for movingly.
