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
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of engine front mounting bracket;
Fig. 2 is the main view of the utility model；
Fig. 3 is the rearview of the utility model；
Fig. 4 is the structural schematic diagram of running channel.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
A kind of cavity plate of engine front mounting bracket precoated sand mold as shown in Fig. 1 ~ Fig. 4, including template 1, before template 1
Side opens up concave die cavity 2, and tooling hole 15 and big centre hole 13, small centre hole 14 through template 1 are offered on rear side of template 1,
It include levorotation chamber 3, right type chamber 4 and the running channel position 9 between levorotation chamber 3 and right type chamber 4 in concave die cavity 2, in concave die cavity 2
Rear portion outside first row air drain 5 is set, rectangular fluting is located on first row air drain 5, so that first row air drain 5 becomes
Segmented air discharge duct is respectively equipped with second row air drain 6 and third air discharge duct 7, levorotation chamber 3 in the outside of levorotation chamber 3 and right type chamber 4
It is respectively provided with the 4th air discharge duct 8 with the front of right type chamber 4, the 4th air discharge duct 8 is located at the two sides of running channel position 9, and fluting 10 is located at
The rear portion of levorotation chamber 3, and be connected to levorotation chamber 3, after molding, fluting 10 and 5 common discharge of first row air drain.
Second row air drain 6 is identical as 5 shape of first row air drain, and the size of second row air drain 6 and third air discharge duct 7
For 1.15-1.2:1,2 it is found that when penetrating sand with reference to the accompanying drawings, since the cavity of levorotation chamber 3 is greater than the cavity of right type chamber 4, to make
The exhaust efficiency of the left and right sides balances, so levorotation chamber 3 needs exhaust velocity faster, so second row air drain 6 is greater than third
Air discharge duct 7.
1 back of template open up tooling hole 15 for installation into penetrating sand machine, be additionally provided in template 1 big centre hole 13,
Small centre hole 14, location hole 12 and sand mouth 11 is penetrated, small centre hole 14 is located at 2 bottom of concave die cavity for ejecting molding arenaceous shell,
Particular number and distribution determine that big centre hole 13 is located at the quadrangle of template 1, for separating cavity plate template according to the structure of mold
With the punch-pin template being used cooperatively with cavity plate template, front and the two connection that sand mouth 11 is located at concave die cavity 2 are penetrated, sand mouth 11 is penetrated
It is 4, is respectively provided with two in levorotation chamber 3 and right 4 front of type chamber and penetrates sand mouth 11, running channel position 9 is arranged in intermediate adjacent two and penetrates
Between sand mouth 11, running channel position 9 is penetrated on the inside of sand mouth 11 with intermediate two and is connected to, and after molding, running channel is placed at running channel position 9, due to
Running channel position 9 is connected to 11 side of sand mouth is penetrated, and can be effectively prevented at running channel position 9 and the phenomenon that sand leakage occurs.
First row air drain 5,6. third air discharge duct 7 of second row air drain are directly connected to the external world, and the 4th air discharge duct 8 is independent
Air discharge duct, and be not connected to directly with the external world, the 4th air discharge duct 8, which is located at, penetrates the ipsilateral of sand mouth 11, and the 4th air discharge duct 8 is as auxiliary row
Air drain cannot influence penetrating sand machine to penetrating in sand mouth 11 and penetrate sand, so the 4th air discharge duct 8 is set as individual slots, not connect directly with the external world
It is logical, prevent the 4th air discharge duct 8 influence to penetrate sand mouth 11 into sand.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
