Description

Technical Field

[0001] The invention relates to the technical field of mold demoulding, and in particular to an integrated hydraulic demoulding force monitoring device. Background Art

[0002] In the mold forming process, demoulding is a key step. The integrated hydraulic demoulding force monitoring device is mainly used in manufacturing fields such as plastic injection molding, rubber molding, metal die casting and composite material molding. By real-time monitoring of demoulding force, it ensures smooth demoulding of products and protects the mold. It is suitable for high-precision parts production and automated production lines.

[0003] The existing demoulding device is driven by a hydraulic system, but the hydraulic system and the mold are mostly separated, resulting in a large and complex structure, inconvenient installation and replacement, and problems such as uneven or excessive demoulding force are prone to occur during the demoulding process, resulting in mold damage or product defects, and it is difficult to monitor the magnitude of the demoulding force in real time. Therefore, it is of great practical significance to develop an integrated hydraulic demoulding force monitoring device with a compact structure, easy installation and replacement, and the ability to monitor the demoulding force in real time. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an integrated hydraulic demolding force monitoring device, which solves the shortcomings of the existing hydraulic demolding device mentioned in the above background technology, namely, the structure is bulky and complicated during use, the hydraulic rod rotates due to external force during the demolding process, the mold cannot be calibrated in real time, and the device cannot be provided with a convenient disassembly and replacement structure.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an integrated hydraulic demolding force monitoring device, comprising a heavy-duty hydraulic cylinder, a demolding force sensor, an anti-rotation chuck column, a lower mold protection type connecting column, an adjustable calibration connecting column and a replaceable demolding rod, a symmetrical fixed plate is installed at the rear of the heavy-duty hydraulic cylinder, a replaceable connecting column is installed below the hydraulic rod of the heavy-duty hydraulic cylinder, and a demolding force sensor is installed below the demolding force sensor, an anti-rotation chuck column is installed below the anti-rotation chuck column, a replaceable demolding rod is installed below the anti-rotation chuck column, an outer column connecting rod is installed between the bottom of the heavy-duty hydraulic cylinder and the structural fixed plate, and an adjustable anti-impact safety limiter is installed above the structural fixed plate, a lower mold protection connecting column is installed below the structural fixed plate, and the interior of the lower mold protection connecting column is embedded with the anti-rotation chuck column, and an adjustable calibration connecting column is installed below the lower mold protection connecting column.

[0006] Preferably, the rear of the heavy-duty hydraulic cylinder is designed with double-sided tripods, which are connected to a symmetrical fixing plate by screws. Four reinforcing studs are installed around the heavy-duty hydraulic cylinder. The reinforcing studs are threadedly connected to the outer column connecting rod. The outer column connecting rod is designed with a side section for easy tightening and is threadedly connected to the structural fixing plate.

[0007] Preferably, the structural fixing plate and the adjustable anti-impact safety limiter are threadedly connected, and a fastening nut is installed on the adjustable anti-impact safety limiter to prevent the thread from loosening due to vibration.

[0008] Preferably, the heavy-duty hydraulic cylinder is connected to the replaceable connecting column by threads, and the replaceable connecting column is designed with a side section for easy tightening, and the replaceable connecting column is connected to the demoulding force sensor by threads.

[0009] Preferably, the demoulding force sensor is designed with symmetrical threaded holes around it, and is connected to the anti-rotation chuck column by threads. The anti-rotation chuck column is designed with four arc-shaped fillets, and is connected to the outer column connecting rod in a sleeve-type manner to achieve an anti-rotation effect.

[0010] Preferably, the anti-rotation chuck column and the replaceable demolding rod are connected by a threaded nut, the anti-rotation chuck column and the lower mold protection type connecting column are connected by a sleeve type, and the lower mold protection type connecting column and the structural fixing plate are connected by a threaded connection.

[0011] Preferably, the lower mold protection connecting column and the adjustable calibration connecting column are connected by a crescent groove thread.

[0012] Preferably, the working steps of the integrated hydraulic demoulding force monitoring device are as follows:

[0013] S1. Install the symmetrical fixing plate at the designated work location through threaded connection. The symmetrical fixing plate can be installed horizontally or vertically. After the heavy-duty hydraulic cylinder and the reinforcement studs are fastened and connected, the outer column connecting rod is threadedly connected to the reinforcement studs. The lower end of the outer column connecting rod is threadedly connected to the structural fixing plate. The demoulding force sensor is selected according to the material required for demoulding. The replaceable connecting column is selected according to the thread size of the demoulding force sensor. The lower end of the replaceable connecting column is designed with an external thread, and the demoulding force sensor is designed with an internal thread. The two are fastened and connected through threads;

[0014] S2. After the demoulding force sensor is selected, first connect the anti-rotation chuck column and the outer column connecting rod by a sleeve, and then connect the anti-rotation chuck column and the demoulding force sensor through symmetrically distributed threaded holes to prevent the hydraulic rod in the heavy-duty hydraulic cylinder from rotating and causing demoulding deviation;

[0015] S3. To prevent the mold from being damaged due to excessive lifting of the heavy-load hydraulic cylinder, an adjustable anti-impact safety limiter installed on the adjustment structure fixing plate plays a protective role. The adjustable anti-impact safety limiter can adjust its extended length by twisting it in different circles. The locking nut installed on it can ensure that the adjustable anti-impact safety limiter will not loosen in an environment with large vibration.

[0016] S4. The replaceable demoulding rod is replaced according to different molds. The external thread on the upper end of the replaceable demoulding rod is connected to the internal thread on the lower end of the anti-rotation chuck column and is fastened with a nut. The anti-rotation chuck column and the replaceable demoulding rod are nested and installed in the lower mold protection type connecting column. The upper end of the adjustable calibration connecting column is designed with four symmetrically distributed crescent grooves, which are connected to the four threaded holes on the lower end of the lower mold protection type connecting column through screws to achieve fine-tuning alignment between the adjustable calibration connecting column and the lower mold.

[0017] The present invention provides an integrated hydraulic demoulding force monitoring device, which has the following beneficial effects:

[0018] 1. The present invention effectively prevents the hydraulic rod of the heavy-duty hydraulic cylinder from rotating due to external force during the demoulding process through the sleeve-type connection between the anti-rotation chuck column and the outer column connecting rod, thereby avoiding demoulding deviation. The arc-shaped rounded corner design of the anti-rotation chuck column is closely matched with the outer column connecting rod to ensure that the transmission direction of the demoulding force is always vertical, significantly improving the precision and stability of demoulding, and solving the problem of incomplete demoulding or mold damage caused by the rotation of the hydraulic rod in traditional demoulding devices.

[0019] 2. The device adopts modular design. The demoulding force sensor and the replaceable demoulding rod are connected by threads, and the adapter parts can be quickly replaced according to different mold requirements. This design not only simplifies the maintenance and replacement process of the equipment, but also improves the versatility and flexibility of the equipment, so that it can be widely used in various manufacturing fields such as plastic injection molding, rubber molding, metal die casting, etc., to meet the precise requirements of different processes for demoulding force.

[0020] 3. The device is equipped with an adjustable anti-impact safety limiter. The extension length can be adjusted by thread, which can effectively limit the stroke of the hydraulic rod and prevent mold damage or equipment failure caused by excessive lifting. In addition, a locking nut is installed on the safety limiter to ensure that the limiter will not loosen in a working environment with large vibrations, further improving the safety and reliability of the equipment and extending the service life of the mold and equipment.

[0021] 4. Through the crescent groove thread connection of the adjustable calibration column and the lower mold protection column, the device can achieve precise alignment and fine-tuning with the mold. This design not only simplifies the installation and debugging process, but also ensures the accuracy of demoulding force transmission, avoids demoulding failure or product defects caused by alignment deviation, and significantly improves production efficiency and product quality.
