Description

Technical Field

[0001] This utility model belongs to the field of mold replacement technology, specifically referring to a mold transfer device. Background Technology

[0002] In industrial production, molds need to be changed frequently, making it a crucial step. Traditional mold replacement methods require manual disassembly, a process that is not only time-consuming and labor-intensive but also prone to operational errors, impacting production efficiency. Manually handling molds is not only physically demanding but also inefficient. Furthermore, the weight of the molds increases the risk of accidents during transport, threatening the safety of operators. On the other hand, some simple transfer equipment cannot accurately position and secure the molds, allowing them to shake, shift, or even fall during transport. This can damage the molds, affecting production progress, and potentially harm surrounding equipment and personnel, especially with large molds that require multiple people to disassemble and install. Therefore, improving mold replacement efficiency and reducing operator workload have become urgent problems to be solved in these fields. Utility Model Content

[0003] In order to overcome the problems of the existing technology, this utility model designs a mold transfer device, which can facilitate the handling and movement of molds and improve efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a mold transfer device, including a base, a frame, a lifting mechanism and a mold support;

[0005] The base is equipped with casters at the bottom, and the frame is mounted on the base. The frame includes a base frame, guide rods and a top frame. Two base frames are mounted on the upper sides of the base, and two guide rods are mounted on the top of each of the two base frames. The top frame is mounted on the top of the two guide rods mounted on the same base frame.

[0006] The lifting mechanism includes a lifting frame and a drive mechanism. Two sliding bearings are provided on both sides of the lifting frame. The lifting frame is mounted on the guide rod through the sliding bearings. The drive mechanism is used to drive the lifting frame to slide up and down along the guide rod.

[0007] The mold bracket is mounted on the lifting frame, and the mold bracket is provided with a mold positioning component for fixing the mold.

[0008] Furthermore, the drive mechanism includes a motor and a screw. The screw is installed between the top frame and the base frame. Rolling bearings are installed on both the top frame and the base frame. The top and bottom ends of the screw are provided with mounting shafts. The mounting shaft at the bottom end of the screw cooperates with the rolling bearing on the base frame, and the mounting shaft at the top end of the screw cooperates with the rolling bearing on the top frame. The motor is installed above the top frame and is used to drive the screw to rotate. Lifting nuts are provided on both sides of the lifting frame, and the lifting nuts cooperate with the screw.

[0009] Furthermore, the drive mechanism also includes a chain, a sprocket, and a protective cover. The mounting shaft at the top of the screw passes through the top frame and is fixedly connected to the sprocket. The motor shaft is connected to the connecting shaft at the top of the screw on one side via a coupling. The sprockets at the tops of the two screws are connected by a chain. The protective cover is used to cover the chain and the sprocket.

[0010] Furthermore, it also includes a control module, which is fixed above the base, and the motor is electrically connected to the control module.

[0011] Furthermore, it also includes height limit sensors, of which there are two. The two height limit sensors are respectively installed at the upper and lower ends of one of the guide rods, and the height limit sensors are electrically connected to the control module. The height limit sensors are photoelectric sensors, and the photoelectric sensors are blocked when the lifting frame moves to the height limit sensor position.

[0012] Furthermore, it also includes a height adjustment button, which is electrically connected to the control module and is disposed on the frame. The height adjustment button includes an up button, a pause button, and a down button.

[0013] Furthermore, the mold positioning assembly includes buffer positioning blocks and locking bolts. Buffer positioning blocks are located at two opposite corners of one end of the mold bracket. These blocks are used to buffer and prevent the mold from being pushed in from the other side of the mold bracket. Threaded holes are provided on both sides of the mold bracket, and the locking bolts are installed in these holes. When the locking bolts are tightened, they press against the side of the mold to prevent it from moving and slipping off the mold bracket.

[0014] Furthermore, the bottom of the mold bracket, on the side away from the buffer positioning block, is provided with two locking clamps. These locking clamps are used to fasten onto the hooks of the storage rack in the mold storage cabinet, fixing the relative position of the transfer device and the mold storage cabinet.

[0015] The mold bracket has an L-shaped stepped interface at its end away from the buffer positioning side. This interface is designed to mate with the complementary shape of the end of the mold storage rack in the mold storage cabinet, serving as a left and right limiting element.

[0016] The beneficial effects of this mold transfer device are as follows: the base is equipped with casters, allowing the transfer device to move flexibly, improving the convenience and efficiency of mold transfer and reducing manual labor intensity; the motor-driven screw drives the lifting frame to slide along the guide rod, achieving stable and precise lifting, eliminating the need for manual handling of molds; the buffer positioning block and locking bolt on the mold bracket accurately position and fix the mold; the control module, combined with the height limit sensor and lifting button, achieves precise motor control and flexible height adjustment, ensuring safe operation of the equipment.

[0025] Furthermore, the drive mechanism 32 includes a motor 321 and a screw 322. The screw 322 is installed between the top frame 23 and the base frame 21. Rolling bearings are installed on both the top frame 23 and the base frame 21. The top and bottom ends of the screw 322 are provided with mounting shafts. The mounting shaft at the bottom end of the screw 322 cooperates with the rolling bearing on the base frame 21, and the mounting shaft at the top end of the screw 322 cooperates with the rolling bearing on the top frame 23. The motor 321 is installed above the top frame 23 and is used to drive the screw 322 to rotate. Lifting nuts 311 are provided on both sides of the lifting frame 31, and the lifting nuts 311 cooperate with the screw 322.

[0026] Furthermore, the drive mechanism 32 also includes a chain, a sprocket, and a protective cover. The mounting shaft at the top of the screw 322 passes through the top frame 23 and is fixedly connected to the sprocket. The rotating shaft of the motor 321 is connected to the connecting shaft at the top of the screw 322 on one side through a coupling. The sprockets at the tops of the two screws 322 are connected by a chain. The protective cover is used to cover the chain and the sprocket.

[0027] In another embodiment, the guide rod 22 is hollow, and the screw 322 is installed inside the guide rod 22. The guide rod 22 has a strip-shaped opening on the side facing the mold bracket 4. Both sides of the lifting frame 31 are connected to the lifting nut 311 through connecting rods. The lifting nut 311 cooperates with the screw 322. The connecting rod passes through the strip-shaped opening. The sprockets at the top of the four screws 322 are connected by chains.

The buffer positioning blocks 41 are used to block and buffer the mold pushed in from the other side of the mold support 4. Threaded holes are provided on both sides of the mold support 4, and the locking bolts 42 are installed in the threaded holes. When the locking bolts 42 are tightened, they can press against the side of the mold to prevent it from moving and avoid the mold slipping off the mold support 4.

[0032] Furthermore, the bottom of the mold bracket 4 on the side away from the buffer positioning block 41 is provided with two locking clamps 43. The locking clamps are used to fasten to the hooks of the storage rack of the mold storage cabinet, fixing the relative position of the transfer device and the mold storage cabinet.
