Description

Technical Field

[0001] The utility model relates to the technical field of sand box positioning and closing devices, in particular to a lost foam casting sand box positioning and closing device. Background Art

[0002] The size and positioning of the sand box in the lost foam casting sand box positioning and closing device play a vital role in the casting of finished parts. If the upper and lower sand boxes are not accurately combined together, it is easy to cause the internal sand mold to move and deviate during mold removal or box turning, which will eventually lead to deviations in product size. The positioning of the sand box closing device generally uses positioning pins on the outside to ensure that the upper and lower sand boxes of the sand box can be tightly closed when closing the box.

[0003] The existing sand box positioning and closing device adopts a double-box positioning and merging method, which requires positioning pins to ensure the closing and merging. The lack of pre-positioning and closing causes the guide deviation of the box opening of the upper sand box during the downward movement, making it difficult to manually align and merge the upper and lower sand boxes. Utility Model Content

[0004] The utility model aims to provide a lost foam casting sand box positioning and closing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions, the lost foam casting sand box positioning and closing device comprises a positioning and closing box rail and a pneumatic cylinder seat, the interior of the positioning and closing box rail is movably installed with a built-in closing box mechanism, and the top of the built-in closing box mechanism is movably installed with a lower closing box locking mechanism, the pneumatic cylinder seat is installed on both sides of the lower closing box locking mechanism, the top of the pneumatic cylinder seat is penetrated by a pneumatic locking rod, hydraulic rods are installed on both sides of the outside of the positioning and closing box rail, and a fixed box is fixed to the top of the hydraulic rod, an upper closing box frame is welded at a fixed position on the fixed box, and an upper closing box group is installed inside the upper closing box frame, and a hydraulic cylinder is arranged at the front end of the positioning and closing box rail.

[0006] Preferably, the upper box closing frame is hydraulically combined with the built-in box closing mechanism through a fixed box and a hydraulic rod.

[0007] Preferably, the pneumatic locking rod and the pneumatic cylinder seat are driven to engage inside the upper closing box assembly on the upper closing box frame.

[0008] Preferably, the built-in box closing mechanism comprises a pneumatic guide rod, a built-in rail and a box closing frame, the movable part of the box closing frame is provided with a built-in rail, and the front end of the box closing frame is installed with a pneumatic guide rod.

[0009] Preferably, the box closing frame is pneumatically driven to the inside of the positioning box closing rail through the internal rail, and the pneumatic guide rod on the box closing frame is inserted into the inside of the hydraulic cylinder.

[0010] Preferably, the lower closing and locking mechanism comprises a closing plate and a pneumatic rod, and the pneumatic rod is installed around the closing plate.

[0011] Preferably, the closing plate is pneumatically driven to rise and fall by a pneumatic rod, and the closing plate is lifted and merged into the upper closing frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model sets a box closing frame, which is aligned with the closing box inside the hydraulic cylinder. The hydraulic cylinder is hydraulically inserted into the pneumatic guide rod. The pneumatic guide rod and the hydraulic cylinder can hydraulically close the box. The lower closing box locking mechanism assembly is positioned and closed by the box closing frame and the built-in rail. The upper closing box frame and the fixed box are hydraulically acted on by the hydraulic rod. The upper closing box frame and the upper closing box assembly can close the box to the inside of the positioning closing rail. The sand box positioning closing device can adopt multiple closing methods to position and close the sand box for lost foam casting. No positioning pins are needed to ensure the merging of the closing boxes. The closing box frame and the built-in rail can be used to pre-position the closing box to avoid the guide deviation of the box opening during the downward movement of the upper sand box.

[0014] 2. The utility model uses a pneumatic rod to move the closing plate. When the upper closing frame and the fixed box are hydraulically acted upon by the hydraulic rod, the upper closing frame and the upper closing group can close the box to the inside of the positioning closing rail. The pneumatic rod can be started first to lift the closing plate to the bottom of the upper closing frame and the upper closing group to pre-position the closing box, thereby preventing the upper sand box from having a guide deviation during the downward movement of the box opening, facilitating manual alignment and merging inspection of the upper and lower sand boxes, and avoiding the occurrence of closing deviation.
