Abstract

The invention discloses a kind of vertical pouring structures 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, and type chamber is obtained after mould assembly, and a cast gate is arranged in each type chamber top.After clay sand mold and overlay film sand mold mould assembly, iron plate is covered in sand mold two sides and facade and is fixed.The present invention can significantly improve the presentation quality of well lid by clay sand mold and the disadvantages of being used in mixed way, overcome clay sand mold poor air permeability of overlay film sand mold;Using vertical pouring structure, the shaping speed of well lid is accelerated, eliminates operation hidden danger, realizes the batch production of well lid.

Description

A kind of vertical pouring structure for producing well lid in batches
Technical field:
The present invention relates to a kind of integrated cast structure for producing well lid, in particular to a kind of vertical pouring knot for producing well lid in batches Structure belongs to casting field.
Background technique:
Using traditional vertical-parting injection molding technique in the Foundry Production of well lid, but this technique is in life Also the shortcomings that having it in terms of producing large-scale well lid and limitation.For vertical-parting injection molding for large cavity, especially type chamber is deeper Casting mold, the hardness of sand mold is not easy uniformly.The large-scale well lid of bunchiness is arranged in casting, adjacent sand mold to be cast behind it, Water translocation is more serious.Due to water translocation, occurs high wet layer in type, substantially reduce sand mold intensity.Therefore in molten metal Dynamic and static pressures effect under, type chamber will deform and influence dimensional accuracy, or even casting mold is caused to collapse, and casting is scrapped.
Overlay film sand mold is solid resin film, and moisture can be ignored, in addition its good permeability, clay sand mold generates when being poured Moisture can exclude in time, the problem of high wet layer in this way, can be readily solved.
In addition, during producing well lid, the casting method being poured using single sandbox, low efficiency, molten iron wave Fei great, there is carry the problems such as dangerous.
Summary of the invention:
The purpose of the present invention is to solve the above problem and provides a kind of vertical pouring structure for producing well lid in batches.For Reach above-mentioned purpose, the invention adopts the 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 precoated sands Type and a platform, it is characterised in that: the clay sand mold and overlay film sand mold replace marshalling on platform, obtain after mould assembly Type chamber;A cast gate is arranged in each type chamber top.
The size of the clay sand mold and overlay film sand mold is 1200mm × 1200mm.
After the clay sand mold and overlay film sand mold mould assembly, iron plate is covered in sand mold two sides and facade and is fixed.
The beneficial effects of the present invention are:
Clay sand mold and the disadvantages of being used in mixed way, overcome clay sand mold poor air permeability of overlay film sand mold, can significantly mention The presentation quality of high well lid.Using vertical pouring structure, the shaping speed of well lid is accelerated, operation hidden danger is eliminated, realizes The batch production of well lid.
Detailed description of the invention
Fig. 1 is the vertical pouring structural schematic diagram before capping iron plate of the present invention.
Fig. 2 is the vertical pouring structural schematic diagram after capping iron plate of the present invention.
Wherein, 1 is overlay film sand mold, and 2 be cast gate, and 3 be clay sand mold, and 4 be type chamber, and 5 be platform, and 6 be iron plate.
Specific embodiment
Following further describes the present invention with reference to the drawings, first will be having a size of 1200mm as shown in attached drawing 1, Fig. 2 The clay sand mold 3 of × 1200mm and the overlay film sand mold 1 having a size of 1200mm × 1200mm are successively alternately arranged neatly, are placed on flat Type chamber 4 is obtained on platform, after mould assembly.Then iron plate 6 is covered in the two sides of sand mold and facade to fix, become " to have from " no case " operation Case " operation.4 top of type chamber is equipped with cast gate 2, and each cast gate 2 is connected with casting machine, while being poured iron into all type chambers 4 Water.According to the demand of well lid, poring rate is determined, and make current-following inoculation, until filling type chamber 4.Above-mentioned casting journey is repeated Sequence, until all models chamber 4 is all poured.After cooling, well lid is taken out from sand mold, well lid cast gate 2 is processed, and is completed Well lid is poured program.
Above-described is only one embodiment of the present invention.For those of ordinary skill in the art, not Under the premise of being detached from the invention design, various modifications and improvements can be made, belongs to protection scope of the present invention.
