Abstract
The utility model relates to a new casting molding box, which comprises a sand box and a molding box body enclosed in the sand box. A pouring path is arranged between a molding chamber positioned on the bottom part of the molding box body and a pouring opening arranged on the top part of the sand box for communication. The utility model is characterized in that the pouring opening is fixedly provided with a bucket-shaped pouring cup. The section of the cup bottom of the pouring cup is provided with a filtering net. The pouring cup can be a sand enclosing cup made of molding sand. The utility model can prevent melting slag and other impurities from entering the molding cavity in order to improve the qualified rate of casting finished products. Meanwhile, the utility model can effectively prevent molten metal from splashing to increase the operating safety.
Description
The utility model relates to Casting Equipment.More particularly, be a kind of casting molding box that is used for pouring cast part.
Casting molding box of the prior art is made of sandbox and the molding box body that encloses in sandbox, offers the sprue gate at its sandbox top, has running channel straight-through between sprue gate and the die cavity.There are the following problems for this version:
1, die cavity together injects in Zhi Tong running channel related molten slag, sand grains and the sand group etc. wherein of molten metal that leave, and is formed on cast(ing) surface, or is included in the foundry goods, causes the foundry goods mechanical performance not reach designing requirement, makes the percent defective of foundry goods high.
2, narrow sprue gate causes the injection difficulty of molten metal to increase, and time has molten metal to splash to cause casualty accident.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of novel casting molding box is provided, and enters die cavity to stop foreign material such as molten slag, sand grains, improves the qualification rate of foundry goods.Another purpose of the present utility model is to improve the sprue gate external form, splashes to avoid molten metal, improves security.
The purpose of this utility model is achieved through the following technical solutions.
The utility model comprises sandbox and the molding box body that encloses in sandbox.The die cavity of molding box body bottom be opened between the sprue gate at sandbox top, the running channel connection is arranged.Design feature of the present utility model is on described sprue gate, fixedly installs bucket-shaped cup, on the cup end section of cup screen pack is set.
Compared with the prior art, the utlity model has following advantage:
1, the setting of screen pack can effectively stop molten slag, sand grains or other foreign material to enter die cavity in the utility model, and then improves the qualification rate of casting finished products.
2, the setting of bucket-shaped cup in the utility model makes that the accurate injection of molten metal is more easy, can effectively avoid splashing of molten metal, and seepage etc. have improved processing safety.
3, the utility model is simple in structure, easy to implement.
Accompanying drawing is the utility model structural representation.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing, in sandbox 1, make molding box body 2 by molding sand, die cavity 3 is positioned at the bottom of molding box body 2, and the sprue gate is opened in the top of sandbox 1, the left and right sides outer setting hanger 9 of sandbox 1.Between die cavity 3 and sprue gate, there is running channel to be communicated with, comprises the sprue 8 that is connected with the sprue gate, be connected the cross gate 6 of sprue 8 belows, and be connected the ingate 7 between cross gate 6 and the die cavity.In the present embodiment, on the sprue gate, fixedly install bucket-shaped cup 4, on the cup end section of cup 4 screen pack 5 is set.Cup 4 can be to enclose the sand cup by what molding sand was made.This height that encloses the sand cup can be at 5～10cm, and enclosing sand will have certain thickness, and compacting, in order to avoid broken up by molten metal when cast.In addition, cup 4 can also be made by other exotic material, and is fixed by molding sand.
Claims (2)
1, a kind of novel casting molding box, comprise sandbox (1) and enclose molding box body (2) in sandbox (1), at the die cavity (3) that is positioned at molding box body (2) bottom and be opened between the sprue gate at sandbox (1) top, there is running channel to be communicated with, it is characterized in that on described sprue gate, fixedly install bucket-shaped cup (4), on the cup end section of cup (4) screen pack (5) is set.
2, novel casting molding box according to claim 1 is characterized in that described cup (4) encloses the sand cup for what made by molding sand.
