Description
Technical Field
The invention relates to a mold exhaust assembly, in particular to a tidal sand mold exhaust spring air needle assembly.
Technical Field
In the casting production of a full-automatic green sand molding production line, the labor intensity of workers can be greatly reduced, and the production efficiency is greatly improved. However, due to the limitation of equipment, some special products have high requirements on the air permeability of the molding sand, and the current automatic production sand mold cannot meet the process requirements required by production, which will result in a large amount of waste products.
Disclosure of Invention
The invention aims to overcome the defects and provide the exhaust spring air needle assembly for the green sand mold, the requirement of actual production can be met by adjusting the air permeability of the sand mold, and meanwhile, different product structures are avoided.
According to the technical scheme, the tidal sand mold exhaust spring air needle assembly comprises a cover plate, an air needle, a guide sleeve, a guide post and a spring, wherein the guide sleeve is fixed on the cover plate, the air needle is arranged at the top of the guide sleeve, the top of the air needle extends to the outside of the guide sleeve, the bottom of the air needle is arranged at an inner hole of the guide sleeve, the spring is further arranged inside the guide sleeve, the bottom of the spring is fixed on the cover plate, the guide post is arranged in the center of the spring, the length of the guide post is smaller than that of the spring, and the top of the spring is connected with the bottom of the air needle.
As a further improvement of the invention, the bottom of the cover plate is provided with a bolt hole.
As a further improvement of the invention, a circle of lug boss is arranged outside the guide sleeve.
As a further improvement of the invention, the guide column is fixed at the bottom of the air needle.
As a further improvement of the invention, the size of the guide post is shorter than that of the spring by more than 80 mm.
The invention has the advantages that: can make the exhaust requirement of sand mould satisfy the technological requirement, simple and convenient, the gas needle length of this design is through spring control simultaneously, and general usefulness is strong, adapts to most product structure, avoids increasing the degree of difficulty for the design, reduce cost.

Detailed Description
The invention is further elucidated in the following on the basis of the drawing.
As shown in fig. 1-3, the tidal sand mold exhaust spring air needle assembly includes a cover plate 1, an air needle 5, a guide sleeve 2, a guide post 3 and a spring 4, the guide sleeve 2 is fixed on the cover plate 1, the air needle 5 is arranged at the top of the guide sleeve 2, the top of the air needle 5 extends to the outside of the guide sleeve 2, the bottom of the air needle 5 is arranged at the inner hole of the guide sleeve 2, the spring 4 is further arranged inside the guide sleeve 2, the bottom of the spring 4 is fixed on the cover plate 1, the guide post 3 is arranged at the center of the spring 4, the length of the guide post 3 is smaller than that of the spring 4, and the top of the spring 4 is connected with the bottom of the air needle.
The bottom of the cover plate 1 is provided with a bolt hole 7 for fixing the whole assembly on a die.
And a circle of bosses 6 are arranged outside the guide sleeve 2 and limit the guide sleeve 2.
The guide post 3 is fixed at the bottom of the air needle 5.
The size of the guide post 3 is shorter than that of the spring 4 by more than 80mm, and the compression amount of the die is met.
The working process of the invention is as follows:
step 1: the shaping plate 13 is at the initial position, the shaping is started, the shaping plate moves into the middle parts of the upper sand-shaped frame and the lower sand- shaped frame 10 and 11,
step 2: the upper sand mold frame 10 is pressed down with the upper compacting plate 8, and the lower sand mold frame 11 is pressed up with the lower compacting plate 9.
And step 3: the height compensation columns 12 on the upper compacting plate 8 contact and compress the air pins to start the sand shooting. And after the sand shooting is finished, the upper and lower compacting plates and the upper and lower sand mold frames return.
And 4, step 4: after the upper and lower compacting plates and the upper and lower sand mold frames are retracted, the shaping plate 13 moves leftward, returns to the initial position, and then the upper sand mold frame 10 moves downward and the lower sand mold frame 11 moves upward to start mold assembling.
And 5: and the upper sand mold frame 10 and the lower sand mold frame 11 are combined to form a complete sand mold. The cavity or riser 14 is vented to atmosphere through a gas needle to improve venting.
