Abstract

The utility model discloses a film-coated sand shell mold for producing a flat gasket. The film-coated sand shell mold comprises a shell, wherein a plurality of die cavities are arranged in the shell; and a sprue gate of a through hole structure is arranged in the middle of the shell. When the film-coated sand shell mold disclosed by the utility model is in use, the shells are overlapped and then form a casting mold; molten iron is cast in the die to cast the flat gasket; a plurality of flat gaskets can be cast at one step; in addition, the film-coated sand shell mold is high in strength; the sizes of the die cavities are accurate; the cast products are completely qualified in size; the defects of sand holes and air holes are eliminated; and the finished product rate of a casting reaches over 98 percent.

Description

A kind of precoated sand shell mould of producing flat shim
Technical field
The utility model relates to flat shim and makes the field, specifically is a kind of precoated sand shell mould of producing flat shim.
Background technology
The flat shim product is the annex on the high iron chair, and product requirement two planes are smooth, and profile and endoporus morpheme size are accurate, no casting flaw (like pore, shrinkage cavity, sand hole etc.), and castings material requires GB/T450-10.In light weight because of flat shim, demand is big, as uses the ordinary sand casting explained hereafter, foundry goods is prone to produce casting flaws such as distortion, sand hole, pore, and the moulding area is big, production efficiency is low, production task is accomplished difficulty.
The utility model content
The technical problem that the utility model will solve provides a kind of precoated sand shell mould of producing flat shim, and it is low to solve ordinary sand casting explained hereafter flat shim production efficiency, the problem of product low precision.
The technical scheme of the utility model is:
A kind of precoated sand shell mould of producing flat shim comprises housing, is provided with a plurality of die cavities in the described housing, and the middle part of housing is provided with the sprue gate of through-hole structure.
Described a plurality of die cavity is at the up column distribution of housing, and is provided with guiding gutter between adjacent two die cavities in every row die cavity group.
Four jiaos of described housing are set to chamfering structure.
The advantage of the utility model: when the utility model uses that a plurality of shell moulds are stacked, form casting mold then; Toward the interior pouring molten iron casting of mould flat shim, it once can cast a plurality of flat shims then, and because the intensity of precoated sand shell mould is high; Cavity dimension is accurate, and the product size after the cast is qualified fully, has eliminated sand holes; Gas hole defect, casting yield reaches more than 98%.
Description of drawings
The vertical view of the utility model.
The specific embodiment
See Fig. 1; A kind of precoated sand shell mould of producing flat shim; Comprise that four jiaos is the housing 1 of chamfering structure, the middle part of housing 1 is provided with the sprue gate 2 of through-hole structure, is provided with eight die cavities 3 in the housing 1; And the structural arrangement of 3 one-tenth two rows of eight die cavities, four row, and be provided with guiding gutter 4 between adjacent two die cavities 3 in every row die cavity group.
