Abstract
The utility model proposes a kind of punch-pin of engine front mounting bracket precoated sand mold, its composition includes: template, convex model chamber is opened up in template, it include levorotation chamber in convex model chamber, right type chamber and the running channel installation position between levorotation chamber and right type chamber, running channel is installed by bolt at running channel installation position, running channel installation position is lower than template surface 1cm-1.2cm in vertical direction, so that running channel is during installation and when penetrating sand, it is more stable, in the rear end of convex model chamber, boss is set, boss is located at right type chamber rear portion, it is to cooperate the fluting on cavity plate that boss, which is arranged, it is more efficient that boss forms arenaceous shell at this, but also has the function of air discharge duct, part mark is additionally provided in levorotation inner cavity surface.The beneficial effect is that: the left right model chamber setting of the utility model and the setting running channel installation position between left right model chamber can effectively provide and penetrate sand efficiency, the presence of boss can increase the edge thickness of arenaceous shell after molding, facilitate the casting of subsequent product.
Description
Technical field
The utility model relates to core shooter tooling field, a kind of engine front mounting bracket precoated sand mold is particularly related to
Punch-pin.
Background technique
Front-suspension bracket is the main component of the engine of automobile, is generally positioned to be the exhaust side of engine, cylinder body lower left,
As shown in Figure 1, front-suspension bracket to a variety of service performances such as the ride comfort of vehicle, stability, passability and fuel economy all
There is important influence.Front-suspension bracket generally is made in the way of sand casting in the related technology, and casting industry is general
All over sand mold is made of precoated sand mold, precoated sand is generally injected by manufacturing process by core shooter has heating dress
In the mold set, high-temperature heating so that close to die surface precoated sand by heat cure, and then form sand mold, the casting of the prior art
Mold used in during making, after moulding by casting is cooling, easily there is the defects of trachoma, viscous sand, burning into sand, entire casting in casting
Intensity is inadequate, does not meet technical requirements, irregular so as to cause product quality, and moulding low efficiency, moulding labor cost are high, nothing
More production costs are increased in shape, product qualification rate hardly results in guarantee.
Utility model content
The utility model to solve problems of the prior art, proposes a kind of engine front mounting bracket overlay film sand mo(u)ld
The punch-pin of tool.
The technical solution of the utility model is achieved in that
A kind of punch-pin of engine front mounting bracket precoated sand mold, including template, open up convex model in the template
Chamber includes levorotation chamber, right type chamber and the running channel installation between the levorotation chamber and the right type chamber in the convex model chamber
Running channel is installed by bolt at the running channel installation position in position, and boss, the boss position is arranged in the rear end of the convex model chamber
In the right type chamber rear portion, part mark is additionally provided in the levorotation inner cavity surface.
Tooling hole is opened up at the template back, big centre hole, small centre hole, location hole are additionally provided in the template,
The small centre hole is located at the punch-pin cavity bottom, fixation hole is equipped in the side of the template, in the bottom of the template
Equipped with bottoming hole, the bottoming hole is located at the lower section of the convex model chamber.
It was equipped with step around the convex model chamber one week, in vertical direction, the step is lower than the upper table of the template
Face.
The beneficial effects of the utility model are: the left right model chamber of the utility model is arranged and is arranged between left right model chamber
Running channel installation position can effectively provide and penetrate sand efficiency, and the presence of step can increase the edge thickness of arenaceous shell after molding, have
Help the casting of subsequent product；
Since cavity is big at levorotation chamber, part mark is set at the surface of levorotation chamber, so that the part mark of casting is more
It is clear to add, and is not likely to produce the connection of mark font；
The product manufactured using the utility model, high yield rate, subsequent mechanical procedure of processing are reduced, and are thereby reduced artificial
With the cost of material.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
