Abstract
The utility model relates to a pump case casting mould. The pump case casting mould comprises a front pressure plate and a back pressure plate. Four pump case module sets are distributed on the front and back pressure plates; each module set comprises two modules which are transversely symmetrically arranged. On the back pressure plate, each module is equipped with a flow gate at one end towards the middle of the back pressure plate; each flow gate is communicated with a sprue between the module sets on the back pressure plate; a sand collecting slot is formed in the tail end of the sprue. The pump case casting mould disclosed by the utility model is simple in structure, convenient to operate, and capable of effectively avoiding phenomena such as unstable wall thickness, cold shut or sand holes of a casting piece during equal-pressure uniform-flow casting performed by a DISA casting process, so that the qualification rate of casting products is improved.
Description
Technical field
The utility model relates to a kind of mold, especially a kind of pump case mold.
Background technology
At present, when pump case is as shown in Figure 1 cast, due to the restriction of template, often by a plurality of modules laterally putting in groups.If while waiting stream cast according to DISA pouring technology is isobaric, because the location of cylindrical core print is inaccurate, and the position that running channel arranges is unreasonable, and occur that casting section thickness is unstable, the phenomenon such as cold shut or sand holes.
Summary of the invention
The purpose of this utility model is to provide a kind of deficiency of the prior art that overcomes, and avoids occurring that wall thickness is unstable in the casting of described pump case, the technical scheme of the problem such as cold shut or sand holes.
The technical solution of the utility model is:
A pump case mold, comprises pressure plate and back-pressure plate.On described positive and negative pressing plate, be laid with four pump case module groups, each module group comprises the module that two lateral symmetry are arranged.On described back-pressure plate, each module is equipped with ingate towards the one end in the middle of pressing plate, and described ingate is connected with the sprue between the module group of being located on this back-pressure plate; End at described sprue is provided with sand catcher.
The length of described ingate is 32mm.
On described pressure plate, the two ends of each module group are equipped with the core print of a wedge shape.
The beneficial effects of the utility model:
The utility model is simple in structure, easy to operate, can effectively avoid when waiting stream cast according to DISA pouring technology is isobaric, occurs that casting section thickness is unstable, the phenomenon such as cold shut or sand holes, has promoted the qualification rate of cast product.
Accompanying drawing explanation
Fig. 1 is pump case foundry goods schematic diagram of the present utility model.
Fig. 2 is the back-pressure plate schematic diagram in the utility model.
Fig. 3 is the pressure plate schematic diagram in the utility model.
Wherein: 1-back-pressure plate; 2-module; 3-sprue; 4-ingate; 5-sand catcher; 6-pressure plate; 7-core print.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figures 2 and 3, the utility model comprises pressure plate 1 and back-pressure plate 6.On described positive and negative pressing plate, be laid with four pump case module groups, each module group comprises the module 2 that two lateral symmetry are arranged.On described back-pressure plate 6, each module is equipped with ingate 4 towards the one end in the middle of pressing plate, and described ingate 4 is connected with the sprue 3 between the module group of being located on this back-pressure plate.The length of described ingate 4 is 32mm, more amid a sharp increase than of the prior art, thereby has increased the area of ingate, has improved the problem of foundry goods ingate trachoma.Described sprue 3 is positioned at the darker position of back-pressure plate 6, thereby can adopt rising pouring pouring technology when cast, makes steadily stamp of molten iron, to prevent foundry goods generation cold shut.End at sprue 3 is also provided with sand catcher 5, and the floating sand in the time of can collecting molten iron stamp in die cavity is inner and affect the quality of foundry goods to avoid it to enter foundry goods.On described pressure plate 1, the two ends of each module group are equipped with the core print 7 of a wedge shape, make the location of positive and negative pressing plate more accurate, avoid occurring the unsettled problem of casting section thickness.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
Claims (3)
1. a pump case mold, comprises pressure plate and back-pressure plate, it is characterized in that being laid with four pump case module groups on described positive and negative pressing plate, and each module group comprises the module that two lateral symmetry are arranged; On described back-pressure plate, each module is equipped with ingate towards the one end in the middle of pressing plate, and described ingate is connected with the sprue between the module group of being located on this back-pressure plate; End at described sprue is provided with sand catcher.
