Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold for processing elevator door hanging panels. Background Technology

[0002] The main function of elevator door rollers is to support the opening and closing of elevator doors, helping them slide on the tracks to allow people and goods to enter and exit the elevator car. Generally, elevator door rollers are made of metal or cast iron, featuring high load-bearing capacity, rust resistance, and wear resistance.

[0003] For example, the multi-station, multi-specification continuous stamping die for elevator hall and car doors, with authorization announcement number "CN217858484U," uses a cylinder to reset the die, which pushes the clamping component to move the sheet metal one station. This not only shortens the sheet metal movement time but also ensures proper fit between the sheet metal and the die body. It also occupies little space and eliminates the need for external drive equipment. However, this device requires stamping to process the elevator door panels, resulting in significant noise pollution that can negatively impact the health of nearby workers. Furthermore, the device does not allow for quick die replacement, leading to prolonged die changes and reduced efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the device affecting the health of operators and low work efficiency, and to propose an elevator door hanging plate processing mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an elevator door panel processing mold, including a box and a mold. The box is slidably connected to the mold surface through a slide rail on its inner surface. The box surface is provided with a mold changing device. An outer shell is fixedly connected to the box surface, and the outer shell penetrates the box surface. The outer shell surface is provided with a noise reduction adjustment device. Through-hole plates are symmetrically fixedly connected to the box surface. Material changing ports are symmetrically opened on the box surface. A worktable is fixedly connected to the inner surface of the box. The worktable is slidably connected to the mold surface through a slide rail on its surface. The mold is slidably connected to a protruding part of the inner wall of the box through a through-hole on its surface.

[0007] Preferably, the mold changing device includes a multi-stage electric push rod and a bracket. One end of the bracket is fixedly connected to the housing. The inner wall of the bracket is fixedly connected to the multi-stage electric push rod. The telescopic end of the multi-stage electric push rod is fixedly connected to the push plate. The rear end of the push plate is symmetrically fixedly connected to a sliding rod. The outer walls of the sliding rods on both sides are slidably connected to through holes opened on the surface of the housing.

[0008] Preferably, a hydraulic cylinder is fixedly connected to the inner surface of the outer shell, and the telescopic end of the hydraulic cylinder passes through the surface of the outer shell and is fixedly connected to the surface of the stamping block.

[0009] Preferably, the surface of the box has an opening, and multiple support rods are fixedly connected to the surface of the box.

[0010] Preferably, the noise reduction adjustment device includes a support box and a second motor. The surface of the support box is fixedly connected to the surface of the outer shell. The surface of the support box is fixedly connected to the second motor via a bracket. The output shaft of the second motor passes through the surface of the support box via a bearing and is fixedly connected to one end of a threaded rod. One end of the threaded rod is rotatably connected to the inner surface of the support box. The surface of the threaded rod is threadedly connected to a threaded block. A crossbar is symmetrically fixedly connected to the surface of the threaded block. One end of each of the crossbars on both sides passes through a slide rail opened on the surface of the support box and is fixedly connected to one end of a connecting rod. One end of each of the connecting rods on both sides is fixedly connected to a baffle.

[0011] Preferably, the surface of the baffle is slidably connected to the through hole on the surface of the through-hole plate, the inner surface of the baffle is provided with a sound insulation cotton layer, and the surface of the support box is fixedly connected to one end of a plurality of support rods.

[0012] The elevator door panel processing mold proposed in this utility model has the following advantages: Through the cooperation of a noise reduction adjustment device and the housing, the elevator door panel is placed into the workbench surface inside the housing through a material exchange port on one side. It can then be transported by operators or other feeding equipment. The output shaft of the second motor rotates, driving the threaded rod to rotate, which in turn drives the threaded block to move downwards. This causes the threaded block to drive the crossbars on both sides to move synchronously, which in turn drives the connecting rods on both sides to move synchronously. The connecting rods on both sides then drive the baffles on both sides to move synchronously, ensuring that one side of the baffles is approximately in contact with the surface of the elevator door panel, thus maintaining a relatively sealed state inside the housing. The extension end of the hydraulic cylinder extends, causing the stamping block to cooperate with the mold to process the elevator door panel material. The noise generated during stamping is blocked by the sound insulation cotton layer inside the housing and the baffles, reducing the noise intensity transmitted to the outside. The relative sealing of the housing by the baffles on both sides further reduces the noise generated during processing, minimizing the impact on the health of the operators.

[0013] By coordinating the mold changing device and the housing, the multi-stage electric push rods are controlled to operate. The extension ends of the multi-stage electric push rods extend, driving the push plate to move synchronously. The push plate can drive the sliding rods on both sides to slide within the through holes on the surface of the housing. When the push plate moves to fit against the mold, it will push the mold to move synchronously, allowing the push rod to push the mold out of the housing for easy replacement by the operator. The first motor is stopped, and the new mold is pushed into the housing. This allows for quick mold replacement, improving the working efficiency of the device. Attached Figure Description

[0028] Working principle:

[0029] When processing elevator door mounting plates:

[0030] Preparation process:

[0031] When mold 7 needs to be replaced, the multi-stage electric push rod 901 is controlled to work, causing the telescopic end of the multi-stage electric push rod 901 to extend and drive the push plate 904 to move synchronously. The push plate 904 can drive the slide rods 903 on both sides to slide in the through holes on the surface of the housing 1. When the push plate 903 moves to fit with mold 7, it will push mold 7 to move synchronously, so that the push rod 903 can push mold 7 out of the housing 1 for easy replacement by the operator. Then, the first motor 901 is stopped, and the new mold 7 is pushed into the housing 1.

[0032] Processing procedure:

[0033] The elevator door mounting plate is placed into the workbench 8 inside the housing 1 through the material exchange port 5 on one side. It can be transported by the operator or other feeding equipment. At the same time, the external power supply of the second motor 202 is turned on, and the output shaft of the second motor 202 is started to rotate, which drives the threaded rod 207 to rotate. The threaded rod 207 drives the threaded block 203 to move downward, which drives the crossbars 204 on both sides to move synchronously. The crossbars 204 on both sides drive the connecting rods 205 on both sides to move synchronously, which drives the baffles 206 on both sides to move synchronously. One side of the baffles 206 on both sides is in close contact with the surface of the elevator door mounting plate, so that the inside of the housing 1 can be in a relatively sealed state. The external power supply of the hydraulic cylinder 11 is turned on, and the extension end of the hydraulic cylinder 11 is started to extend, which drives the stamping block 10 to cooperate with the mold 7 to process the raw material of the elevator door mounting plate. The noise generated during stamping is blocked by the sound insulation cotton layer 3 inside the housing 1 and the baffle 206, reducing the noise intensity transmitted to the outside.
