Abstract
The utility model discloses a vertical pouring structure of batch production well lid, including a plurality of clay sand moulds, a plurality of tectorial membrane sand mould and a platform. The size of clay sand mould and tectorial membrane sand mould is 1200mm, and clay sand mould and tectorial membrane sand mould NULL on the platform are neat, obtains the die cavity after closing the type, and every die cavity upper portion sets up a runner. Clay sand mould and tectorial membrane sand mould are fixed with the top iron and screw board in sand mould both sides and facade after closing the type. The use that mixes of clay sand mould and tectorial membrane sand mould is passed through in the invention, has overcome clay sand mould gas permeability subalternation shortcoming, can show the appearance quality who improves the well lid, adopt vertical pouring structure for the shaping speed of well lid, eliminated operation hidden danger, realized the batch production of well lid.
Description
Technical field:
The present invention relates to a kind of cast structure of producing well lid, particularly a kind of vertical pouring structure producing well lid in batches, belongs to casting field.
Background technology:
What adopt in the Foundry Production of well lid is traditional vertical-parting injection molding technique, but this technique also has its shortcomings and limitations in the large-scale well lid of production.Vertical-parting injection molding is for the darker casting mold of large die cavity, particularly die cavity, and the hardness of sand mold is not easily even.The large-scale well lid of arrangement bunchiness is when pouring into a mould, and adjacent sand mold to be cast after it, water translocation is comparatively serious.Due to water translocation, there is high wet layer in type, sand mold intensity is reduced greatly.Therefore under the using dynamic and static pressures effect of molten metal, die cavity will deform and affect dimensional accuracy, and even cause casting mold to cave in, foundry goods is scrapped.
Overlay film sand mold is solid resin film, and moisture can be ignored, and adds its good permeability, and the moisture produced during the cast of clay sand mold can be got rid of in time, and the problem of high like this wet layer can be readily solved.
In addition, in the process of producing well lid, adopt single sandbox to carry out the casting method of pouring into a mould, efficiency is low, and molten iron waste is large, there is the problems such as carrying danger.
Summary of the invention:
The object of the invention is to solve the problem and provide a kind of vertical pouring structure producing well lid in batches.In order to achieve the above object, present invention employs following technical scheme:
A kind of vertical pouring structure producing well lid in batches of the present invention, comprises multiple clay sand mold, multiple overlay film sand mold and a platform, it is characterized in that: described clay sand mold and overlay film sand mold replace marshalling on platform, obtain die cavity after mould assembly; Described each die cavity top arranges a cast gate.
Described clay sand mold and the size of overlay film sand mold are 1200mm × 1200mm.
After described clay sand mold and overlay film sand mold mould assembly, add a cover iron plate fixing in sand mold both sides and facade.
Beneficial effect of the present invention is:
Clay sand mold and overlay film sand mold used in combination, overcomes the shortcomings such as clay sand mold poor air permeability, can significantly improve the presentation quality of well lid.Adopt vertical pouring structure, accelerate the shaping speed of well lid, eliminate operation hidden danger, achieve the batch production of well lid.
Accompanying drawing explanation
Fig. 1 of the present inventionly adds a cover the vertical pouring structural representation before iron plate.
Fig. 2 of the present inventionly adds a cover the vertical pouring structural representation after iron plate.
Wherein, 1 is overlay film sand mold, and 2 is cast gates, and 3 is clay sand molds, and 4 is die cavities, and 5 is platforms, and 6 is iron plates.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further, as shown in accompanying drawing 1, Fig. 2, first the clay sand mold 3 being of a size of 1200mm × 1200mm is alternately arranged neatly successively with the overlay film sand mold 1 being of a size of 1200mm × 1200mm, is placed on platform, after mould assembly, obtains die cavity 4.Then add a cover iron plate 6 to fix in the both sides of sand mold and facade, become " having case " operation from " without case " operation.Die cavity 4 top is provided with cast gate 2, and each cast gate 2 is connected with casting machine, simultaneously toward pouring molten iron in all die cavities 4.According to the demand of well lid, determine poring rate, and make current-following inoculation, until fill die cavity 4.Repeatedly carry out above-mentioned cast program, until all die cavities 4 are all poured.After cooling, from sand mold, take out well lid, well lid cast gate 2 is processed, complete well lid cast program.
Above-described is only one embodiment of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, some distortion and improvement can also be made, all belong to protection scope of the present invention.
