Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a mold exchange platform. Background Technology

[0002] Molds are an indispensable tool in industrial production. They are used to process the shape of objects by changing the physical state of materials and are known as the "mother of industry". When it is necessary to change the mold during the molding process, a mold changing device is usually required.

[0003] Traditional mold changing devices typically use clamps to fix and move molds, but this is cumbersome and inefficient. To address the shortcomings of traditional mold changing devices, a mold changing device using multiple shafts and servo motors has emerged. This device can ensure that if one servo motor fails, the other motors can still work normally, thus ensuring the safety and reliability of the device. However, the use of multiple servo motors results in a complex structure and high manufacturing costs.

[0004] Therefore, there is an urgent need for a mold changing device that is simple in structure, low in cost, easy to operate, and more efficient to meet the needs of modern industrial production. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a mold exchange platform that is simple in structure, low in cost, easy to operate, and more efficient.

[0006] To address the aforementioned problems, this utility model provides a mold exchange platform, including a mold exchange frame and a mold replacement mechanism mounted on the mold exchange frame. The mold replacement mechanism includes multiple rollers rotatably mounted on the mold exchange frame and a drive motor fixed on the mold exchange frame for driving the rollers to rotate. Each roller includes a front drive roller, a rear drive roller, and at least one driven roller sequentially arranged between the front drive roller and the rear drive roller. One end of the front drive roller, one end of the rear drive roller, and one end of the driven roller are each fixed with a gear and a chain for meshing with the gears. The drive motor includes a first motor and a second motor. A first clutch is fixed between the first motor and the mold exchange frame. The output end of the first motor is drivenly connected to the input end of the first clutch, and the output end of the first clutch is fixed to the other end of the front drive roller. A second clutch is fixed between the second motor and the mold exchange frame. The output end of the second motor is drivenly connected to the input end of the second clutch, and the output end of the second clutch is fixed to the other end of the rear drive roller.

[0007] Compared with existing technologies, the advantages of this utility model are as follows: This utility model adopts a dual-motor and dual-clutch combined chain gear transmission assembly, which effectively simplifies the structure and reduces costs. This dual-motor design allows for flexible switching of working modes. Even if one motor fails, the other motor can continue to work, ensuring the continuity of mold changing operations, improving mold changing efficiency, avoiding downtime caused by single motor failure, and enhancing production safety, stability, and reliability. Operation is also more convenient. Specifically, when the first motor is working, it engages with the first clutch, driving the front drive roller to rotate via the gears and chain. Under the synergistic effect of the first motor, other rollers are driven to rotate, ultimately achieving the goal of multiple rollers rotating simultaneously. When the first motor is working, the second motor is disengaged from the second clutch and is in a non-working state. Conversely, when the second motor is working, it is engaged with the second clutch, driving the rear drive roller to rotate. Under the synergistic effect of gears and chains, it drives other rollers to rotate synchronously. When the second motor is working, the first motor is disengaged from the first clutch and is in a non-working state. This design effectively avoids downtime caused by single motor failure, improves production safety and stability, and ensures the smooth operation of the production process.

[0008] As an improvement, at least a pair of uprights are fixed to the mold changing frame, positioned on either side of the frame. Each upright is equipped with a grating ruler for measuring mold height. This improvement, by fixing the uprights to the mold changing frame and installing the grating ruler, enables automatic measurement of mold height. If the mold height is incorrect, the mold changing operation immediately stops, effectively eliminating safety hazards caused by incorrect mold placement, preventing accidents caused by cross-use of molds, and improving production safety. Furthermore, the automatic measurement function is unaffected by manual intervention or duplicate mold identification card numbers, simplifying the operation process and improving work efficiency.

[0009] As an improvement, the bottom of the mold changing frame is equipped with a translation mechanism for driving the mold changing frame to move left and right on the track. The translation mechanism includes a first and a second set of drive wheels supported on both sides of the bottom of the mold changing frame, a first motor for driving the rotation of the first set of drive wheels, and a second motor for driving the rotation of the second set of drive wheels. This improvement, by setting a translation mechanism at the bottom of the mold changing frame, enables the mold changing frame to move left and right on the track. Operators can quickly align the mold changing frame with the injection molding machine, simplifying the mold changing process, improving mold changing efficiency, reducing the labor intensity of operators, and increasing production efficiency. The translation mechanism adopts a structure combining a motor and wheels, which is simple in structure, easy to install and maintain, and has high reliability and stability. At the same time, it can achieve precise control to ensure accurate docking between the mold changing frame and the injection molding machine, further improving mold changing efficiency, reducing the labor intensity of operators, and increasing production efficiency.

[0010] As an improvement, a set of mold changing mechanisms is arranged side-by-side on the mold changing frame. A driven wheel set is positioned between the first and second driving wheel sets, located between the mold changing mechanisms and supported at the bottom of the mold changing frame. This improvement, by arranging a set of mold changing mechanisms side-by-side on the mold changing frame and adding a driven wheel set for auxiliary support, enables rapid mold changing, reduces the number of times the mold changing frame needs to be moved, and improves operational efficiency. Simultaneously, the driven wheel set can effectively support excessively heavy molds or mold changing frames that are too long in the lateral direction, preventing the mold changing frame from tilting or vibrating during movement, improving the safety of mold changing operations, reducing the risk of production accidents, saving manpower and resources, and increasing production efficiency.

[0011] As an improvement, multiple partitions are spaced apart from front to back on the mold changing frame. These partitions are located between adjacent rollers and are lower than the top height of the rollers. This improvement effectively fills the gaps between adjacent rollers by adding partitions to the mold changing frame, providing support for the molds sliding on the rollers. This ensures smooth sliding of the molds on multiple rollers, preventing jamming or displacement, improving mold changing efficiency, and enhancing the overall stability and reliability of the mold exchange platform.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2As shown, in this utility model, the mold exchange platform includes a mold changing frame 1 and a mold changing mechanism 2 disposed on the mold changing frame 1. The mold changing mechanism 2 includes multiple rollers rotatably disposed on the mold changing frame 1 and a drive motor fixed on the mold changing frame 1 for driving the rollers to rotate. The rollers include a front drive roller 31, a rear drive roller 32, and at least one driven roller 33 sequentially disposed between the front drive roller 31 and the rear drive roller 32. A gear 41 is fixed to one end of the front drive roller 31, one end of the rear drive roller 32, and one end of the driven roller 33, and is provided with a gear for meshing. The chain 42 connected to the gear 41 drives a motor including a first motor 51 and a second motor 52. A first clutch 61 is fixed between the first motor 51 and the mold changing frame 1. The output end of the first motor 51 is connected to the input end of the first clutch 61. The output end of the first clutch 61 is fixed to the other end of the front drive roller 31. A second clutch 62 is fixed between the second motor 52 and the mold changing frame 1. The output end of the second motor 52 is connected to the input end of the second clutch 62. The output end of the second clutch 62 is fixed to the other end of the rear drive roller 32.

[0019] When the first motor 51 is working, it engages with the first clutch 61, driving the front drive roller 31 to rotate. With the coordinated action of the gear 41 and chain 42, it drives the other rollers to rotate, ultimately achieving simultaneous rotation of multiple rollers. When the first motor 51 is working, the second motor 52 disengages from the second clutch 62 and is in a non-working state. Conversely, when the second motor 52 is working, it engages with the second clutch 62, driving the rear drive roller 32 to rotate. With the coordinated action of the gear 41 and chain 42, it drives the other rollers to rotate synchronously. When the second motor 52 is working, the first motor 51 disengages from the first clutch 61 and is in a non-working state.

[0020] This utility model adopts a dual-motor and dual-clutch combined chain gear transmission component, which effectively simplifies the structure and reduces costs. This dual-motor design can flexibly switch working modes. Even if one motor fails, the other motor can continue to work, ensuring the continuity of mold changing operations, improving mold changing efficiency, avoiding downtime caused by single motor failure, improving production safety, stability and reliability, and making operation more convenient.

[0021] like Figure 2As shown, at least a pair of columns 11 are fixed on the mold changing frame 1, with the pair of columns 11 arranged on the left and right sides of the mold changing frame 1. A grating ruler 12 for measuring mold height is installed on each column 11. Specifically, the grating ruler 12 includes a transmitter and a receiver fixed on the pair of columns 11, and the mold height is measured through the coordinated operation of the transmitter and receiver. This improvement, by fixing the columns 11 and installing the grating ruler 12 on the mold changing frame 1, achieves automatic measurement of mold height. When the mold height is incorrect, the mold changing operation immediately stops, effectively eliminating safety hazards caused by incorrect mold insertion, avoiding safety accidents caused by cross-use of molds, and improving production safety. At the same time, the automatic measurement function is unaffected by manual intervention or duplicate mold identification card numbers, simplifying the operation process and improving work efficiency.

[0022] like Figure 3 As shown, the bottom of the mold changing frame 1 is equipped with a translation mechanism 7 for driving the mold changing frame 1 to move left and right on the track. The translation mechanism 7 includes a first drive wheel set 71 and a second drive wheel set 72 supported on both sides of the bottom of the mold changing frame 1, a first moving motor 81 for driving the rotation of the wheel of the first drive wheel set 71, and a second moving motor 82 for driving the rotation of the wheel of the second drive wheel set 72. This improvement, by setting the translation mechanism 7 at the bottom of the mold changing frame 1, realizes the left and right movement of the mold changing frame 1 on the track. The operator can quickly align the mold changing frame 1 with the injection molding machine, simplifying the mold changing process, improving mold changing efficiency, reducing the labor intensity of the operator, and improving production efficiency. The translation mechanism 7 adopts a structure of motor combined with wheel set, which is simple in structure, easy to install and maintain, and has high reliability and stability. At the same time, it can achieve precise control to ensure that the mold changing frame 1 is accurately docked with the injection molding machine, further improving mold changing efficiency, reducing the labor intensity of the operator, and improving production efficiency.

[0023] like Figure 3 As shown, a set of mold changing mechanisms 2 are arranged side-by-side on the mold changing frame 1. A driven wheel set 73 is arranged between the first drive wheel set 71 and the second drive wheel set 72. The driven wheel set 73 is located between the set of mold changing mechanisms 2 and supported at the bottom of the mold changing frame 1. This improvement, by arranging a set of mold changing mechanisms 2 side-by-side on the mold changing frame 1 and adding the driven wheel set 73 for auxiliary support, enables rapid mold changing, reduces the number of times the mold changing frame 1 is used, and improves operational efficiency. At the same time, the driven wheel set 73 can effectively support excessively heavy molds or mold changing frame 1 with excessive lateral length, preventing the mold changing frame 1 from tilting or vibrating during movement, improving the safety of mold changing operations, reducing the risk of production accidents, saving manpower and resources, and improving production efficiency.

[0024] In this utility model, the first driving wheel set 71, the second driving wheel set 72 and the driven wheel set 73 each include a pair of rollers arranged in front and behind and a connecting shaft fixed between the rollers. The rollers are rotatably mounted at the bottom of the mold changing frame 1 through bearings. The connecting shaft of the first driving wheel set 71 is connected to the output end of the first moving motor 81, and the connecting shaft of the second driving wheel set 72 is connected to the output end of the second moving motor 82.

[0025] like Figure 2 As shown, multiple partitions 9 are spaced apart from front to back on the mold changing frame 1. The partitions 9 are located between two adjacent rollers and their height is lower than the top height of the rollers. This improvement, by setting partitions 9 on the mold changing frame 1, effectively fills the gap between adjacent rollers, provides support for the mold sliding on the rollers, ensures that the mold slides smoothly on multiple rollers, avoids jamming or displacement, improves mold changing efficiency, and enhances the overall stability and reliability of the mold exchange platform.

[0026] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
