Abstract
The utility model discloses a hollow camshaft sand core mold. The mold comprises a stationary mold and a movable mold, wherein the stationary mold and the movable mold are provided with electric heating holes which penetrate through the mold body; thermocouples are arranged in the electric heating holes; multiple cavities are formed in parting surfaces of the stationary mold and the movable mold; an air exhaust groove is formed between every two cavities; a core-pulling mechanism is arranged on a parting surface between the stationary mold and the movable mold; a core-pulling pin guide mechanism is arranged on the parting surface; an orientation mechanism is arranged on the movable mold; multiple core support fixing seats are arranged on each cavity. Gases in the cavities are emitted under the action of sand ejection pressure, so that the ejected sand can be compact and is reliably cured, the sand core yield is improved, and the minimum diameter of the sand core can be 6mm. Meanwhile, multiple cavities are formed in the parting surface, so that batch production of the sand core can be realized.
Description
Technical field
The utility model belongs to casting technology field, is specifically related to a kind of hollow camshaft core mold.
Background technology
Casting, is that Metal Melting is smelt and meets necessarily required liquid and water in casting mold, obtains the technical process of the foundry goods (part or blank) of reservation shape, size and performance through cooled and solidified, after leveling processing.Casting is one of fundamental technology of modern mechanical manufacturing industry, and the development of foundry machinery industry indicates a national production strength.The blank of Foundry Production is with low cost, for part complex-shaped, that particularly have complicated inner cavity, more can demonstrate its economy; Its adaptability is wider simultaneously, and has good comprehensive mechanical performance.
In cast hollow camshaft, need in sand mold, place core, so that form cavity volume in the camshaft that casting forms, because camshaft is more elongated, therefore needed core is more elongated, adopts current mould to manufacture the core core-breaking rate of gained higher, and every modulus amount is few, can not mass production, cannot meet large production requirement.
Utility model content
The purpose of this utility model is to provide a kind of hollow camshaft core mold, and when manufacturing elongated core, every sand core output quantity is many, and the yield rate of core is high.
For achieving the above object, technical solution adopted in the utility model is:
This mould comprises quiet mould, and quiet mould connects dynamic model; Quiet mould and dynamic model are equipped with the electrical heating hole connecting in die body, and thermocouple is set in electrical heating hole; On the die joint that quiet mould is connected with dynamic model, all there are a plurality of die cavities, between every two die cavities, are provided with exhaust groove; Core-pulling mechanism is arranged on the die joint between quiet mould and dynamic model, is provided with the pin guiding mechanism of loosing core on die joint; On dynamic model, be provided with detent mechanism; On each die cavity, be provided with a plurality of stud holders.
Preferably, stud holder is embedded on die cavity.
Preferably, dynamic model and quiet mould are equipped with 8 die cavities.
The beneficial effect that this core mold produces is: on the die joint being connected with dynamic model at quiet mould, die cavity is set, between every two die cavities, be provided with exhaust groove, gas in die cavity is discharged under shooting pressure effect, can make to penetrate sand consolidation, solidify reliable, improve core yield rate, core diameter minimum can reach 6 millimeters.Meanwhile, die joint upper impression is a plurality of, can realize the mass production of core.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram of dynamic model or quiet mould die joint.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, this mould comprises quiet mould 1, and quiet mould 1 connects dynamic model 2; Quiet mould 1 and dynamic model 2 are equipped with the electrical heating hole 10 connecting in die body, the interior thermocouple that arranges of electrical heating hole 10; On the die joint 3 that quiet mould 1 contacts with dynamic model 2, all have a plurality of die cavities 4, described die cavity 4 is semicircle, between every two die cavities 4, is provided with exhaust groove 5; Core-pulling mechanism 6 is arranged on the die joint 3 between quiet mould 1 and dynamic model 2, is provided with the pin guiding mechanism 7 of loosing core on die joint 3; On dynamic model 2, be provided with attitude reference device 8; On each die cavity 4, be provided with a plurality of stud holders 9.
The preferred a kind of embodiment of this mould is that stud holder 9 is embedded on die cavity 4.
The preferred a kind of embodiment of this mould is that dynamic model 1 and quiet mould 2 are equipped with 8 die cavities 4.
This mould is placed on core shooter and uses, thermocouple heating mould, and core sand is injected mold cavity 4 from top, and after thermocouple is heating and curing, the pin of loosing core exits, and quiet mould 1 is separated with dynamic model 2 disengagements, takes out the plug of making.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model is limited; in the protection domain of spirit of the present utility model and claim, any modification and change that the utility model is made, all fall into protection domain of the present utility model.
