Problems solved by technology
However, for rough castings, the surface of the opening of the cavity is rough and uneven. When this method is used for pressure testing, there will be water and air leakage at the opening of the cavity, making it impossible to perform pressure testing.
After all the castings are finished, the pressure inspection is carried out. The risk cost for the casting manufacturer is high, especially for iron castings. If leakage occurs, the castings will be scrapped, resulting in a waste of finishing costs.

Embodiment Construction
[0014] Such as figure 1 — image 3 Shown is the cavity pressure detection device of the card-type blank casting of the present invention. The pressure detection device is used to detect the casting 1 such as figure 1 Shown is a cavity 2 with openings on the opposite side of the cavity 2 and the sealing performance of the blank casting cavity with the outer end faces of the two openings parallel. The pressure detection device includes a door-shaped card tool 6, a door-shaped card tool 6 The two side walls correspond to the two open ends of the casting cavity 2. Between the two side walls of the door-shaped card tooling 6 and the open end of the casting 1, there is a rubber pad 3 for sealing the opening of the casting and a rubber pad for pressing The pressure plate 5 of 3, the two side walls of the door-shaped card tooling 6 are threadedly connected with a plurality of force-pushing screws 4 for pressing the pressure plate 5, and the pressure plate 5 is respectively provided with...

The invention relates to a clamp-type blank casting cavity pressure detection device in the sealing performance detection technology of the casting cavity. The two opening ends of the cavity correspond to each other, and a rubber pad for sealing the opening of the casting and a pressing plate for pressing the rubber pad are provided between the two side walls of the door-shaped clip tooling and the opening end of the casting. The two side walls of the type tooling are threadedly connected with a number of strong pushing screws that press the pressure plate, and the pressure plate is respectively provided with an inlet and an outlet connected with the casting cavity, the inlet is connected with the inlet pipe, and the outlet is connected through the outlet pipe. Connect with pressure gauge. The pressure detection device of the present invention is specially suitable for the pressure detection of the cavity of the casting with the cavity having symmetrical openings and the outer end faces of the two openings are parallel, the detection tooling is convenient to disassemble and the detection efficiency is high.
Description
Technical field [0001] The invention relates to a sealing detection technology for a casting cavity, in particular to a cassette type blank casting cavity pressure detection device, which is used to detect the blank casting cavity with an opening on the opposite surface of the casting cavity and the outer ends of the two openings are parallel. Sealing performance. Background technique [0002] Some castings with cavities in the foundry industry are generally used as oil cavities, circulating water cavities, compression cavities, etc. Therefore, they must be pressure tested during quality inspection to ensure that the cavity has good sealing and no leakage. risk. At present, the pressure inspection of this type of casting cavity is to process bolt holes on the flange surface of the cavity opening after finishing the casting, connect the plate with the opening of the cavity with bolts, and then perform hydraulic pressure inspection. However, for the rough castings, the surface of...
