Abstract
The utility model discloses a die for an aluminum rear cover of a motor. The die comprises a stripping die plate, a die plate and a sand box, wherein the stripping die plate is arranged between the die plate and the sand box; the die plate passes through the stripping die plate and then extends into the sand box; a sand mould in match with the die plate is arranged in the sand box; the stripping die plate, the die plate and the sand box are integrally connected by locating pins; and an ejector rod is arranged on the stripping die plate. By adopting the die, the sand mould can be prevented from being damaged during drawing, and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of mould, specifically a kind of mould for aluminium matter motor rear cover.
Background technology
In elevator, motor rear cover is complex-shaped, adds man-hour, because the motor rear cover pattern draft is little, complex-shaped, very easily causes sand mold to damage when molding, and production efficiency is low.
Summary of the invention
The problem that exists in order to overcome prior art, the purpose of this utility model is to provide a kind of mould for aluminium matter motor rear cover, adopts this mould can not cause sand mold to damage when molding, and production efficiency is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of mould for aluminium matter motor rear cover is characterized in that: this mould comprises stripping pattern plate, template and sandbox, and described stripping pattern plate is arranged between template and sandbox; Template extend in sandbox after passing stripping pattern plate, is provided with the sand mold suitable with template in sandbox, and stripping pattern plate, template and sandbox link together by alignment pin; Be provided with push rod on stripping pattern plate.
In the utility model, stripping pattern plate is that the aluminium matter of thickness 20mm is dull and stereotyped.The length of stripping pattern plate is greater than the length of template.Gap between stripping pattern plate and template is 0.5mm.
Be provided with pin-and-hole outside sandbox, alignment pin is arranged in pin-and-hole after passing stripping pattern plate, template.
Adopt the utility model can not cause sand mold to damage when molding, production efficiency is high.The utility model is applicable to that apperance is high, pattern draft is little, in the foundry goods moulding of difficult molding.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of mould for aluminium matter motor rear cover described in the utility model is seen Fig. 1, and this mould comprises stripping pattern plate 1, template 2 and sandbox 3, and stripping pattern plate 1 is arranged between template 2 and sandbox 3; Template 2 extend in sandbox 3 after passing stripping pattern plate 1, is provided with the sand mold 4 suitable with template 2 in sandbox 3, and stripping pattern plate 1, template 2 and sandbox 3 link together by alignment pin 5; Be provided with push rod 6 on stripping pattern plate 1.
Stripping pattern plate is that the aluminium matter of thickness 20mm is dull and stereotyped, and stripping pattern plate length is greater than template.Intermediate shape coordinates with it, and fit clearance is 0.5mm, and making stripping pattern plate and template do the used time at push rod can free lifting.During moulding, template is fixed on moulding machine, and after sand mold compacting, push rod withstands stripping pattern plate, holds sandbox and sand mold by stripping pattern plate, upwards ejects apperance.
Adopt the utility model can not cause sand mold to damage when molding, production efficiency is high, is applicable to that apperance is high, pattern draft is little, in the foundry goods moulding of difficult molding.
