Description

Technical Field

[0001] This utility model belongs to the field of transportation and transfer technology, specifically a mold transfer mechanism. Background Technology

[0002] When processing certain agricultural products and fruits, a pressure molding process is required. This process typically utilizes molds, where the product is placed in a mold cavity and pressure is applied using a press to shape it. However, because some agricultural products and fruits are prone to springback after being compressed, continuous pressure must be maintained within the mold for a certain period to achieve the final shape. Therefore, a self-locking mechanism is usually incorporated into the mold structure to achieve continuous pressure molding. To ensure consistency in molding time across batches, molds are often stacked sequentially from bottom to top for storage and transport.

[0003] Some existing problems include: the overall height of the molds after stacking is relatively high, and existing mold-removing devices have certain difficulties in clamping and manipulating them, making it difficult to achieve stable and accurate pick-and-place operations. In addition, there is a certain distance between the stacking station and the delivery station. If a simple two-point direct transfer method is used, the overall efficiency is low; while excessive speed may pose safety hazards. Therefore, a more suitable mold transfer mechanism is proposed to solve the above technical problems. Utility Model Content

[0004] To address the above problems, this utility model provides a mold transfer mechanism to solve the issues of inconvenience in picking up and placing molds when they are stacked to a high position, low picking and placing efficiency, and low safety factor.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A mold transfer mechanism includes a horizontally arranged support arm, a support frame connected to the bottom of the support arm to support and raise it, and an auxiliary bracket located in the middle of the support arm. The space between the auxiliary bracket and the support frame forms a first working position and a second working position. The first working position is used to place a mold stacking device, and the second working position is used to place a mold delivery device.

[0007] The auxiliary support is equipped with a transition platform for temporarily placing the mold, and the support cross arm is equipped with at least two spaced clamping mechanisms for sequentially moving and transferring the mold from the first working position, the transition platform, and the second working position.

[0008] As a further improvement to the above solution, a support plate is fixedly installed on the upper surface of the transition platform to support the mold.

[0009] As a further improvement to the above solution, a reinforcing plate is fixedly installed on the top surface of the supporting cross arm, and a guide rail is fixedly installed on the reinforcing plate to facilitate the guiding movement of the clamping mechanism. Limiting components for limiting the clamping mechanism are also fixedly installed at both ends of the guide rail.

[0010] As a further improvement to the above solution, a rack is also provided on the top of the reinforcing plate, and a drive mechanism is provided on the clamping mechanism. The drive mechanism and the rack cooperate with each other to reciprocate above the support crossarm.

[0011] As a further improvement to the above solution, the clamping mechanism includes a slide that moves on the support cross arm, a connecting seat that can move vertically and vertically below the slide, a first drive component that is fixedly mounted on the slide, and the output end of the first drive component is connected to the connecting seat.

[0012] The bottom of the connecting seat is movably provided with sliding seats symmetrically arranged along the central axis of the connecting seat. Each sliding seat on each side is fixedly provided with a clamping component for clamping the mold. A second drive assembly is also connected to one side of the sliding seat.

[0013] As a further improvement to the above solution, the top of the connecting seat is fixedly provided with several guide members that slide relative to the slide, for linear guidance of the connecting seat's up and down movement.

[0014] A limiting post is also fixedly installed on the top of the connecting seat. The limiting post slides against the slide, and a limiting platform is fixedly installed on the top of the limiting post.

[0015] As a further improvement to the above solution, the clamping member has an "L"-shaped structure with one end facing downwards, and the end facing downwards also has a clamping boss. The clamping boss is detachably engaged with the positioning groove on the mold to achieve stable clamping of the mold.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The clamping mechanism is erected at a high position by a support frame, auxiliary bracket, and support crossarm, with reserved first and second working positions for cooperation with the mold stacking device and mold delivery device. This ensures a small movement distance between the clamping mechanism and the mold, facilitating control during clamping and transportation. The transition platform and two clamping mechanisms allow the mold to be transferred to the transition platform first, and then transported to the mold delivery device at the second working position, avoiding excessively long transfer distances for the clamping mechanism. Transferring the mold to the transition platform allows for easy adjustment of different clamping mechanisms, improving transfer efficiency and avoiding safety risks during the transfer process.

[0018] 2. By setting a reinforcing plate at the top of the support crossarm, the supporting effect of the support crossarm can be strengthened. The guide rail and rack can facilitate the clamping mechanism to smoothly reciprocate on the support crossarm, thereby completing the transportation of the mold.

[0019] 3. The slide and the connecting seat are driven by the first drive component to lift and lower the position, thereby completing the picking and placing of the mold from one position to another. Under the action of the limiting post and the limiting stage, the vertical clamping stroke of the connecting seat and the clamping parts can be limited. Especially when the first drive component fails, it can play a final safety guarantee to prevent the connecting seat, clamping parts and the clamped mold from falling. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] like Figure 1-5As shown, the specific solution of this embodiment is as follows: a mold transfer mechanism includes a horizontally arranged support arm 1, a support frame 2 connected to the bottom of the support arm 1 to support and raise it, and an auxiliary support 3 located in the middle of the support arm 1. The space between the support frame 2 and the auxiliary support 3 on both sides forms a first working position 4 and a second working position 5. The first working position 4 is used to place a mold stacking device, and the second working position 5 is used to place a mold delivery device. For details, please refer to the attached document. Figure 3 ;

[0028] The auxiliary support 3 is provided with a transition platform 6 for temporarily placing the mold. At least two clamping mechanisms 7 are movably arranged at intervals on the support cross arm 1. In this embodiment, two clamping mechanisms 7 are provided to transport and transfer the mold sequentially from the first working position 4, the transition platform 6, and the second working position 5. Specifically, the clamping mechanism 7 on the side closer to the first working position 4 takes the mold off the mold stacking device and then places it on the transition platform 6. Further, a support plate 61 is fixedly provided on the upper surface of the transition platform 6 for supporting the mold. The clamping mechanism 7 on the side closer to the second working position 5 clamps the mold placed on the transition platform 6 and then places it on the mold delivery device. Thus, in this application, the mold can be quickly and safely transferred by the two clamping mechanisms 7 in conjunction with the transition platform 6 in the middle position.

[0029] As a preferred embodiment of the above, a reinforcing plate 11 is fixedly provided on the top surface of the supporting cross arm 1. The reinforcing plate 11 is specifically a flat plate structure. A guide rail 12 is fixedly provided on the reinforcing plate 11 to facilitate the guiding movement of the clamping mechanism 7. Limiting members 14 for limiting the clamping mechanism 7 are also fixedly provided at both ends of the guide rail 12. In this embodiment, the limiting member 14 is specifically a limit limit switch. The limit switch is connected to the controller signal of the entire device. When the limit switch is triggered, the controller controls the clamping mechanism 7 to stop moving. The scheme of using the limit switch in conjunction with the controller to control the device moving on the guide rail to stop moving is the prior art and is provided on equipment that needs to move in a straight direction, such as machine tools. It will not be described in detail here.

[0030] The top of the reinforcing plate 11 is also provided with a rack 13. The clamping mechanism 7 has a drive mechanism. The drive mechanism and the rack 13 cooperate with each other to reciprocate above the support cross arm 1. Specifically, the drive mechanism includes a fixed drive motor. The output shaft of the drive motor is connected to a drive gear. The drive gear meshes with the rack 13. Therefore, when the motor starts, the movement control of the clamping mechanism 7 on the support cross arm 1 can be realized through the cooperation of the gear and the rack 13.

[0031] As a preferred embodiment of the above embodiments, the clamping mechanism 7 includes a slide 71 that moves on the supporting cross arm 1. In this embodiment, the drive motor of the drive mechanism is fixedly mounted on the slide 71, and a connecting seat 72 that can move vertically is provided below the slide 71. (Refer to the attached drawing) Figure 4 , 5 A first drive assembly 75 is fixedly installed on the slide 71. The output end of the first drive assembly 75 is connected to the connecting seat 72. Specifically, the first drive assembly 75 is an electric push rod. Several guide members 73 that slide and cooperate with the slide 71 are fixedly installed on the top of the connecting seat 72 for linear guidance of the up and down movement of the connecting seat 72. A limiting post 74 is also fixedly installed on the top of the connecting seat 72. The limiting post 74 slides and cooperates with the slide 71. A limiting platform 741 is fixedly installed on the top of the limiting post 74. The limiting post 74 and the limiting platform 741 can prevent the connecting seat 72 and the mold below from falling when the first drive assembly 75 fails, thus achieving mechanical protection.

[0032] The bottom of the connecting seat 72 is movably provided with sliding seats 76 symmetrically arranged along the central axis of the connecting seat 72. Each sliding seat 76 on each side is fixedly provided with a clamping member 77. The clamping member 77 has an "L"-shaped structure with one end facing downwards, and the downward-facing end also has a clamping boss 771. The clamping boss 771 is detachably engaged with the positioning groove on the mold to achieve stable clamping of the mold. A second drive assembly 78 is also connected to one side of the sliding seat 76. The second drive assembly 78 is a cylinder. During the specific clamping and transfer of the mold by the clamping mechanism 7, the drive mechanism first drives the sliding seat 71 to move to the top of the mold. Then, driven by the first drive assembly 75, the connecting seat 72 and the clamping member 77 descend. Driven by the second drive assembly 78, the clamping member 77 clamps the mold. After the mold is clamped, it is driven to rise by the first drive assembly 75. After the drive mechanism moves the slide 71 to the next position, the first drive assembly 75 drives the connecting seat 72 to descend. After the mold is placed, the second drive assembly 78 drives the clamping member 77 to release the mold. Then, the first drive assembly 75 drives the connecting seat 72 and the clamping member 77 to rise. The drive mechanism drives the slide 71 to move to the mold removal position again, ready to pick up and transfer the next mold.
