In this way, the utility model relates to a novel under casting mould for piston of loosing core, with original manual production methods change for semi -automatic mechanized production, adopt semi -automatic casting machine production head casting combustion chamber piston, process is controlled by time relay, duty cycle is stable, controllable, can effectively guarantee the product castability, improves the as cast production efficiency of combustion chamber piston, has reduced the waste of casting material, has reduced to say behind the product processing volume, has improved the economic value of product.
Description
Technical field
The utility model relates to Piston Casting mould, particularly relate to a kind of novel under to loose core casting piston mould.
Background technology
Along with the day by day maturation of domestic engine technology, its market demand progressively increases, in order to improve production capacity, the machining process monitoring ability of product, semi-automatic casting machine of loosing core under my company has purchased, and progressively carry out this technique, product quality and production efficiency are obtained for and significantly improve, but the piston of such as certain type 105 cylinder diameter, because head combustion chamber requires casting, combustion chamber cannot be arranged at piston-top surface, the mode of loosing core by hand only can be adopted to produce.But the mode productivity ratio of hand-operated core pulling is extremely low, labour intensity is high again, namely adds the labour intensity of workman, again reduces production efficiency, cannot meet Production requirement.
Rising head is arranged in piston-top surface by traditional lower core-pulling die, the object of perfect foundry goods is obtained again by the pressure cooling of internal mold, but it exists, and quality is low, the shortcoming of founding materials waste, significantly increases casting cost and the processing cost of product, thus affects the market value of product.
Utility model content
The technical problem that the utility model mainly solves be to provide a kind of novel under to loose core casting piston mould, original manual production mode is changed to semi automatic machineization to produce, semi-automatic casting machine is adopted to produce head casting piston of combustion chamber, technical process is controlled by the time relay, working cycles is stable, controlled, can effectively ensure product castability, improve the production efficiency of piston of combustion chamber casting, reduce the waste of founding materials, reduce road processing capacity after product, improve the economic worth of product.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: casting piston mould of loosing core under providing one novel, comprise backform, external mold, positioning sleeve, internal mold and side riser, described backform one end is embedded in external mold top, one end is higher than plane on external mold in addition, described side riser vertically connects the side of external mold, it is inner that described positioning sleeve one end is embedded in external mold baseplane, one end is higher than baseplane in addition, and described internal mold is sleeved on the inner and end face of positioning sleeve higher than positioning sleeve end face.
In the utility model preferred embodiments, described side riser side is provided with sprue and cross gate, and described cross gate one end is connected to side riser bottom, and one end is connected with bottom sprue in addition.
In the utility model preferred embodiments, described sprue and side riser erect center line and become 15 ~ 25 degree of angles to arrange, and sprue top is horn mouth shape.
In the utility model preferred embodiments, described side riser inner surface is provided with heat-insulation layer.
The beneficial effects of the utility model are: casting piston mould of loosing core under the utility model one is novel, original manual production mode is changed to semi automatic machineization to produce, semi-automatic casting machine is adopted to produce head casting piston of combustion chamber, technical process is controlled by the time relay, working cycles is stable, controlled, can effectively ensure product castability, improve the production efficiency of piston of combustion chamber casting, reduce the waste of founding materials, reduce road processing capacity after product, improve the economic worth of product.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 be of the present utility model novel under to loose core the structural representation of casting piston mould one preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment provides following technical scheme.
A kind of novel under to loose core casting piston mould, comprise backform 1, external mold 2, positioning sleeve 3, internal mold 4 and side riser 5, described backform 1 one end is embedded in external mold 2 top, one end is higher than plane on external mold 2 in addition, described side riser 5 vertically connects the side of external mold 2, described positioning sleeve 3 one end is embedded in that external mold 2 baseplane is inner, and one end is higher than baseplane in addition, and described internal mold 4 is sleeved on the inner and end face of positioning sleeve 3 higher than positioning sleeve 3 end face.
Further, described side riser 5 side is provided with sprue 6 and cross gate 7, described cross gate 7 one end is connected to side riser 5 bottom, one end is connected with bottom sprue 6 in addition, sprue 6 and side riser 5 erect center line and become 15 ~ 25 degree of angles to arrange, and sprue 6 top is horn mouth 61 shape, be beneficial to casting stream smooth.
In above-mentioned, under casting die of loosing core side riser 5 is placed in piston side, between cross gate and piston blank, whole side riser 5 inner cavity surface is provided with heat-insulation layer, improves side riser 5 position insulating power, and the cooling water cavity Final 8 on recycling backform 1 and internal mold 4 freezes but piston blank, piston blank is cooled rapidly, and strengthen the thermograde relatively emitting port part, force the aluminium liquid in side riser 5 chamber to flow into foundry goods, reach the object of Piston Casting feeding.
The beneficial effects of the utility model are: casting piston mould of loosing core under the utility model one is novel, original manual production mode is changed to semi automatic machineization to produce, semi-automatic casting machine is adopted to produce head casting piston of combustion chamber, technical process is controlled by the time relay, working cycles is stable, controlled, can effectively ensure product castability, improve the production efficiency of piston of combustion chamber casting, reduce the waste of founding materials, reduce road processing capacity after product, improve the economic worth of product.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
