Description

Technical Field

[0001] This utility model relates to the technical field of mold changing moving devices, specifically a height-adjustable mold changing trolley. Background Technology

[0002] Currently, it is known that existing hydraulic presses, such as those mainly used for manufacturing automotive interior parts, often lack height-adjustable mold-changing devices. The closest comparable devices use electric motors for transmission, which also suffer from the inability to adjust height. A search revealed a Chinese patent with authorization publication number CN218342930U, which discloses a height-adjustable rapid mold-changing moving device. This device includes a rapid mold-changing carriage, track assemblies located on both sides of the bottom of the carriage, and a drive mechanism positioned between the bottom and the track assemblies. The device includes an upper template, a lower template, and lifting support plates fixed to the left and right sides of the upper and lower templates respectively. A hydraulic cylinder drive system and a telescopic hydraulic cylinder are installed between the upper and lower templates. The hydraulic cylinder drive system is fixed to the lower template. The drive mechanism is fixed to the bottom of the lower template. A pin locking device is also provided between the upper and lower templates. The advantages are: strong applicability, applicable to most hydraulic presses, applicable to most conventional molds, and high efficiency in height adjustment. Compared with the transmission method of conventional mold changing trolley devices, this device can quickly and conveniently adjust the height.

[0003] However, in actual use, due to the height of the track components, the quick mold change vehicle body needs to be lifted by equipment to contact the track components. This method is not only cumbersome, but also prone to positional deviation, causing derailment. Utility Model Content

[0004] To address the problem that existing mold-changing trolleys are inconvenient to deploy onto tracks, this invention provides a mold-changing trolley with adjustable height.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A height-adjustable mold-changing trolley includes a lower mold plate, with column assemblies mounted at the four corners of the top surface of the lower mold plate, and an upper mold plate mounted on the top surface of the column assemblies; a drive mechanism located at the top of the lower mold plate, with its top end connected to the bottom surface of the upper mold plate; and a lower support mechanism located at the bottom of the lower mold plate, comprising a lifting plate and a limiting rod, with the limiting rod inserted through the bottom surface of the lower mold plate, its bottom end connected to the top surface of the lifting plate, a lead screw threaded to one side of the lifting plate, pulleys mounted at the four corners of the bottom surface of the lifting plate, and a motor mounted on the top surface of the lower mold plate, the output end of which is connected to the top end of the lead screw.

[0007] Furthermore, brackets are installed at the four corners of the bottom surface of the lower template, and rollers are rotatably connected to the bottom end of the brackets.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it provides a mobile support for the mold changing trolley, the rollers can rotate freely, the trolley can be easily moved on the workshop floor, it is convenient to move the trolley to the mold changing position, reduce the difficulty of manual pushing, and reduce the labor intensity of operators.

[0009] Furthermore, the bottom surface of the roller is slidably connected to a slide rail.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the rollers and slide rails work together to provide a precise moving track for the mold changing trolley. The trolley slides along the slide rails, avoiding deviation or slippage during movement, ensuring the accuracy of the trolley's movement path. This is especially suitable for mold changing scenarios with high requirements for movement accuracy, and it also reduces the shaking of the trolley during movement, ensuring the stability and safety of the mold during transportation.

[0011] Furthermore, the column assembly includes an outer cylinder, the top surface of the lower template is fitted with the outer cylinder, and a lifting rod is slidably connected inside the outer cylinder. The top end of the lifting rod extends to the top of the outer cylinder and is connected to the bottom surface of the upper template.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, when the drive mechanism adjusts the height of the upper template, the lifting rod can extend and retract within the outer cylinder, enhancing the stability of the connection between the upper and lower templates and preventing the upper template from tilting or swaying. This structure provides reliable guidance and support for the height adjustment of the mold changing trolley, ensuring a smooth and safe height adjustment process.

[0013] Furthermore, the outer wall of the lifting rod is provided with scale lines.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it provides operators with an intuitive height reference. When adjusting the height of the upper template, the lifting distance can be accurately controlled by reading the scale lines, achieving precise height adjustment to meet the accurate requirements of different molds for installation height and avoid affecting the mold installation and use effect due to height adjustment errors.

[0015] Furthermore, the driving mechanism includes a hydraulic cylinder, a chassis is mounted on the bottom end of the hydraulic cylinder, the chassis is connected to the top surface of the lower template, and a top plate is connected to the output end of the hydraulic cylinder, the top plate is connected to the bottom surface of the upper template.

[0016] The advantage of adopting the above-mentioned further solution is that it can provide a stable and large driving force, and quickly and smoothly realize the raising and lowering of the upper template.

[0017] Furthermore, a gap is provided between the motor and the hydraulic cylinder.

[0018] The advantage of adopting the above-mentioned further solution is that maintaining the distance can prevent the two from interfering with each other during operation and ensure that their respective functions are performed normally.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This height-adjustable mold-changing trolley, through the coordinated use of a column assembly, drive mechanism, motor, and lower support mechanism, enables autonomous height adjustment. This not only facilitates mold-changing operations but also allows the trolley to smoothly navigate onto the track. The lower and upper mold plates, along with the column assembly, form the trolley's basic frame, providing stable support for the mold. The drive mechanism connects the upper and lower mold plates, allowing adjustment of the upper mold plate's height to accommodate mold changes of varying heights. In the lower support mechanism, a motor drives a lead screw, which in turn moves a lifting plate along a limit rod, adjusting the trolley's overall height above the ground. This ensures the pulleys contact the bottom, providing support for the trolley's overall structure, until the rollers at the bottom of the lower mold plate contact the slide rail, completing the trolley's mounting operation.

[0028] Please see Figures 1-5This utility model provides a technical solution: a height-adjustable mold-changing trolley, including a lower mold plate 100, with column assemblies 300 respectively installed at the four corners of the top surface of the lower mold plate 100, and an upper mold plate 200 installed on the top surface of the column assemblies 300; a drive mechanism 400, which is located on the top of the lower mold plate 100 and its top end is connected to the bottom surface of the upper mold plate 200; and a lower support mechanism 500, which is located at the bottom of the lower mold plate 100 and includes a lifting plate 5001 and a limiter. A limiting rod 5002 is inserted into the bottom surface of the lower template 100. The bottom end of the limiting rod 5002 is connected to the top surface of the lifting plate 5001. A lead screw 5004 is threaded onto one side of the lifting plate 5001. Pulleys 5003 are installed at the four corners of the bottom surface of the lifting plate 5001. A motor 600 is installed on the top surface of the lower template 100. The output end of the motor 600 is connected to the top end of the lead screw 5004. The lower template 100, the upper template 200, and the column assembly 300 constitute the basic frame of the mold changing trolley, providing stable support for the mold. The drive mechanism 400 connects the upper and lower templates and can adjust the height of the upper template to adapt to the mold changing needs of different heights. In the lower support mechanism 500, the motor 600 drives the lead screw 5004 to rotate, which in turn drives the lifting plate 5001 to rise and fall along the limit rod 5002, adjusting the overall height of the trolley off the ground and causing the pulley 5003 to contact the bottom, so that it can support the overall structure of the mold changing trolley until the roller 900 at the bottom of the lower template 100 can contact the slide rail 700, thereby completing the upper rail operation of the mold changing trolley.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As an embodiment of this utility model, further, brackets 800 are installed at the four corners of the bottom surface of the lower template 100, and rollers 900 are rotatably connected to the bottom end of the brackets 800 to provide mobile support for the mold changing trolley. The rollers 900 can rotate freely, so that the trolley can be easily moved on the workshop floor, making it convenient to move the trolley to the mold changing position, reducing the difficulty of manual pushing and reducing the labor intensity of operators.

[0031] As one embodiment of this utility model, the bottom surface of the roller 900 is slidably connected to the slide rail 700. The roller 900 and the slide rail 700 cooperate to provide a precise moving track for the mold changing trolley. The trolley slides along the slide rail 700, avoiding deviation or slippage during movement and ensuring the accuracy of the trolley's movement path. This is especially suitable for mold changing scenarios with high requirements for movement accuracy, and it can also reduce the shaking of the trolley during movement, ensuring the stability and safety of the mold during transportation.

[0032] As one embodiment of this utility model, the column assembly 300 further includes an outer cylinder 3001. The outer cylinder 3001 is mounted on the top surface of the lower template 100. A lifting rod 3002 is slidably connected inside the outer cylinder 3001. The top end of the lifting rod 3002 extends to the top of the outer cylinder 3001 and connects to the bottom surface of the upper template 200. When the drive mechanism 400 adjusts the height of the upper template 200, the lifting rod 3002 can extend and retract within the outer cylinder 3001, enhancing the stability of the connection between the upper and lower templates and preventing the upper template from tilting or shaking. This structure provides reliable guidance and support for the height adjustment of the mold changing trolley, ensuring a smooth and safe height adjustment process.

[0033] As one embodiment of this utility model, the outer wall of the lifting rod 3002 is further provided with scale lines 3003, providing operators with an intuitive height reference. When adjusting the height of the upper template 200, the lifting distance can be accurately controlled by reading the scale lines 3003, achieving precise height adjustment to meet the precise requirements of different molds for installation height, and avoiding the impact of height adjustment errors on mold installation and usage.

[0034] As an embodiment of this utility model, the driving mechanism 400 further includes a hydraulic cylinder 4001, a chassis 4002 is mounted on the bottom end of the hydraulic cylinder 4001, the chassis 4002 is connected to the top surface of the lower template 100, the output end of the hydraulic cylinder 4001 is connected to a top plate 4003, and the top plate 4003 is connected to the bottom surface of the upper template 200, which can provide a stable and large driving force to quickly and smoothly realize the lifting and lowering of the upper template 200.

[0035] As an embodiment of this utility model, a gap is provided between the motor 600 and the hydraulic cylinder 4001. Maintaining this gap can prevent mutual interference between the two during operation and ensure that their respective functions are performed normally.

[0036] Specifically, the working principle of this height-adjustable mold-changing trolley is as follows: In the initial state, the motor 600 drives the lead screw 5004 to rotate. The lead screw 5004 is threadedly engaged with the lifting plate 5001, causing the lifting plate 5001 to rise along the limit rod 5002, causing the pulley 5003 to contact the ground and support the overall structure of the mold-changing trolley. As the lifting plate 5001 continues to rise, until the roller 900 at the bottom of the lower template 100 contacts the slide rail 700, the upper rail operation is completed. At this time, the trolley can slide freely along the slide rail 700 via the roller 900, precisely moving to the mold changing position. When the height of the upper template 200 needs to be adjusted to fit different molds, the hydraulic cylinder 4001 of the drive mechanism 400 is activated. The base plate 4002 at the bottom of the hydraulic cylinder 4001 is fixed to the top surface of the lower template 100, and the top plate 4003 at its output end is connected to the bottom surface of the upper template 200. The upper template 200 is raised and lowered by hydraulically driving the top plate 4003. At the same time, the lifting rod 3002 of the column assembly 300 extends and retracts synchronously inside the outer cylinder 3001 to ensure that the upper template 200 rises and falls smoothly and avoids tilting and swaying. The scale lines 3003 on the outer wall of the lifting rod 3002 allow the operator to accurately control the lifting distance. Throughout the process, the motor 600 and the hydraulic cylinder 4001 maintain a distance from each other and do not interfere with each other, stably performing their respective functions to achieve flexible adjustment and precise movement of the mold changing trolley, and efficiently complete the mold changing work.
