Abstract
The invention discloses a kind of vertical pouring structure for producing well lid in batches, including multiple clay sand molds, multiple overlay film sand molds and a platform.The size of clay sand mold and overlay film sand mold is 1200mm × 1200mm, and clay sand mold and overlay film sand mold replace marshalling on platform, die cavity is obtained after mould assembly, and each die cavity top sets a cast gate.After clay sand mold and overlay film sand mold mould assembly, add a cover iron plate in sand mold both sides and facade and fix.The present invention is used in mixed way by clay sand mold and overlay film sand mold, the shortcomings of overcome clay sand mold poor air permeability, can significantly improve the presentation quality of well lid；Using vertical pouring structure, the shaping speed of well lid is accelerated, eliminate operation hidden danger, realize the batch production of well lid.
Description
Technical field：
The present invention relates to a kind of integrated cast structure for producing well lid, more particularly to a kind of vertical pouring structure for producing well lid in batches belongs to casting field.
Background technology：
Traditional vertical-parting injection molding technique is used in the Foundry Production of well lid, but this technique also has its shortcomings and limitations in terms of large-scale well lid is produced.The vertical-parting injection molding casting mold deeper for large cavity, particularly die cavity, the hardness of sand mold is difficult uniformly.The large-scale well lid of bunchiness is arranged in cast, adjacent sand mold to be cast behind it, water translocation is more serious.Due to water translocation, occur wet layer high in type, substantially reduce sand mold intensity.Therefore under the dynamic and static pressures effect of molten metal, die cavity will deform and influence dimensional accuracy, or even cause casting mold to cave in, and casting is scrapped.
Overlay film sand mold is solid resin film, and moisture can be ignored, and adds its good permeability, and the moisture that clay sand mold is produced when pouring into a mould can be excluded in time, and the problem of wet layer so high can be readily solved.
In addition, during well lid is produced, the casting method poured into a mould using single sandbox, efficiency is low, molten iron wastes big, there are problems that carrying.
The content of the invention：
A kind of vertical pouring structure for producing well lid in batches is provided it is an object of the invention to solve the above problems.In order to achieve the above object, present invention employs following technical scheme：
A kind of vertical pouring structure for producing well lid in batches of the present invention, including multiple clay sand molds, multiple overlay film sand molds and a platform, it is characterised in that：The clay sand mold and overlay film sand mold replace marshalling on platform, and die cavity is obtained after mould assembly；Described each die cavity top sets a cast gate.
Described clay sand mold and the size of overlay film sand mold are 1200mm × 1200mm.
After the clay sand mold and overlay film sand mold mould assembly, add a cover iron plate in sand mold both sides and facade and fix.
The beneficial effects of the present invention are：
Clay sand mold and overlay film sand mold are used in mixed way, and the shortcomings of overcome clay sand mold poor air permeability, can significantly improve the presentation quality of well lid.Using vertical pouring structure, the shaping speed of well lid is accelerated, eliminate operation hidden danger, realize the batch production of well lid.
Brief description of the drawings
Fig. 1 is the vertical pouring structural representation added a cover before iron plate of the present invention.
Fig. 2 is the vertical pouring structural representation added a cover after iron plate of the present invention.
Wherein, 1 is overlay film sand mold, and 2 is cast gate, and 3 is clay sand mold, and 4 is die cavity, and 5 is platform, and 6 is iron plate.
Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings, as shown in accompanying drawing 1, Fig. 2, size is placed on platform for the overlay film sand mold 1 that the clay sand mold 3 and size of 1200mm × 1200mm are 1200mm × 1200mm is alternately arranged neatly successively first, die cavity 4 is obtained after mould assembly.Then add a cover iron plate 6 in the both sides of sand mold and facade to fix, " having case " operation is become from " without case " operation.The top of die cavity 4 is provided with cast gate 2, and each cast gate 2 is connected with casting machine, while toward pouring molten iron in all of die cavity 4.According to the demand of well lid, poring rate is determined, and make current-following inoculation, until filling die cavity 4.Above-mentioned cast program is repeated, until all die cavities 4 are all poured.After cooling, well lid is taken out from sand mold, 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, various modifications and improvements can be made, belongs to protection scope of the present invention.
