Description

An automated clamping device for shell casting Technical Field

[0001] This utility model relates to the field of shell casting technology, and in particular to an automated clamping device for shell casting. Background Technology

[0002] Shell casting is a casting method in which preheated and hardened molding sand is placed on a metal mold heated to 180 to 280 degrees Celsius. The molding sand is a high-strength thermosetting material, such as silica sand or zircon sand. This mixture with resin forms a thin-shell mold, which is then poured to obtain the casting. Often, a mold consists of two shell molds joined together, clamped together or bonded with resin. Once the shell molds are assembled, casting can begin. Some castings, such as drill bits, can be made into a single shell mold. The material preparation process and shell-making process vary slightly from factory to factory. The shell casting clamping device is used to hold and fix the outer shell mold during casting, preventing misalignment due to heat impact or thermal expansion.

[0003] Existing shell casting molds typically involve simple upper and lower mold closing, followed by simple clamping or mechanical / hydraulic fixation. This fixation method is relatively basic. During shell casting, thermal expansion and contraction can cause misalignment, leading to casting tilt, misalignment marks, and affecting casting quality. Furthermore, clamping devices usually require manual clamping, lacking sufficient automated clamping capabilities and offering limited operational convenience. Therefore, we propose an automated clamping device for shell casting to address these issues. Summary of the Invention

[0030] The beneficial effects of this solution are as follows: By combining the upper mold 1 and the lower mold 2 into one unit, the clamping adapter 5 is attached to both sides of the lower mold 2, and the top of the automatic clamping component 4 is clamped onto the clamping adapter 5. Due to the gravity of the upper mold 1, when it moves downward, the auxiliary automatic clamping block 6 can assist in clamping and installing on the automatic clamping component 4, completing the secondary clamping. The automatic clamping is convenient. The adjusting and fixing sleeve 7 is pulled upward to disengage from the clamping support frame 3, so that the automatic clamping component 4 can swing back and forth, thereby disengaging from the clamping adapter 5 and the auxiliary automatic clamping block 6. The assembly and disassembly are convenient, the automatic clamping is stable, and the assembly and disassembly are convenient.

[0031] When the mold is closed, the anti-offset column 10 can be stably inserted into the positioning anti-offset tube 9, so that it is not easy to tilt or shift during mold closing and casting. At the same time, the automatic clamping component 4, clamping adapter 5 and auxiliary automatic clamping block 6 are installed stably during clamping, and the anti-offset fixation is stable.

The adjusting and fixing sleeve 7 is engaged with the connection between the fixing clamping support frame 3 and the automatic clamping component 4, which provides support for the clamping support frame 3. The upper mold 1 is provided with clamping adapter seats 5 and auxiliary automatic clamping blocks 6 on both sides.

[0048] When the upper mold 1 and the lower mold 2 are assembled into one piece, the clamping adapter 5 first fits and engages with both sides of the lower mold 2, and then the top of the automatic clamping component 4 engages with the clamping adapter 5. Due to the gravity of the upper mold 1, it can move downward automatically to complete the automatic clamping. The auxiliary automatic clamping block 6 can assist in clamping and is installed on the automatic clamping component 4 to complete the secondary clamping. The automatic clamping component 4 is installed in the gap between the clamping adapter 5 and the auxiliary automatic clamping block 6, making automatic clamping convenient.

[0049] Pulling the adjusting fixed sleeve 7 upwards causes it to disengage from the clamping support frame 3, changing the fixed connection between the clamping support frame 3 and the automatic clamping assembly 4 from a fixed connection to a hinged connection. This allows the automatic clamping assembly 4 to swing back and forth, thus disengaging from the clamping adapter seat 5 and the auxiliary automatic clamping block 6. This makes disassembly and assembly convenient, and the automatic clamping is stable.

[0050] The upper mold 1 is provided with plug-in anti-deviation pillars 10 on both the front and rear sides, and the lower mold 2 is provided with positioning anti-deviation tubes 9 on both the front and rear sides. When the upper mold 1 and the lower mold 2 are closed, the plug-in anti-deviation pillars 10 can be stably plugged into the positioning anti-deviation tubes 9, so that it is not easy to tilt or deviate during mold closing and casting. At the same time, the automatic clamping component 4, the clamping adapter seat 5 and the auxiliary automatic clamping block 6 are installed stably when clamping, and the anti-deviation fixation is stable. The clamping adapter seat 5 plays an auxiliary clamping and anti-deviation effect, resulting in high casting accuracy. The device is easy to automate clamping operations, has excellent clamping and assembly capabilities, is easy to operate, and has high mold closing accuracy, excellent anti-deviation and anti-misalignment capabilities, and high casting accuracy.
