DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Example 1: See Figure 1-Figure 5 The present invention provides a technical solution: an injection molding machine aluminum template welding device, comprising a workbench 1, a fixed plate 2 is fixedly connected to the back of the workbench 1, a welding device 3 is fixedly connected to the top of the fixed plate 2, and also includes:

[0033] The movable mechanism 4 comprises a connecting plate 401, a connecting plate 401 is provided on the side of the workbench 1 away from the fixed plate 2, a slider 403 is slidably connected to the inner wall of the connecting plate 401, a pressing plate 402 is provided on the top of the slider 403, a side of the pressing plate 402 close to the connecting plate 401 is fixedly connected to the connecting plate 401, a first sliding rod 405 is fixedly connected to the side of the pressing plate 402 away from the fixed plate 2, a pushing rod 404 is slidably connected to the outer wall of the first sliding rod 405, a first spring 408 is fixedly connected to the side of the pushing rod 404 away from the slider 403, and the first spring 408 is provided to push and press the pushing rod 404 to ensure that the pushing rod 404 is firmly fitted with the pressing plate 402, a side of the first spring 408 away from the slider 403 is fixedly connected to the load-bearing plate 406, and the slider 4 03 A positioning rod 407 is fixedly connected to one side close to the push rod 404, and the outer wall of the positioning rod 407 is in contact with the first spring 408. The outer wall of the positioning rod 407 is slidably connected to the push rod 404, and a contact rod 410 is provided on the inner wall of the positioning rod 407. Support rods 409 are fixedly connected to the left and right sides of the contact rod 410. By providing the support rods 409, the load-bearing plate 406 can be effectively supported, so that after the load-bearing plate 406 completes pressing the first spring 408, the support rods 409 can limit the movement of the load-bearing plate 406, thereby ensuring that the first spring 408 does not rebound. Two groups of support rods 409 are fixedly connected to the contact rod 410 on one side thereof, and the moving mechanism 4 is provided in two groups and are symmetrically arranged with the middle of the workbench 1 as the center, and the push rod 404 is used to fix the load-bearing plate 406.

[0034] The working principle of this embodiment is as follows: when the template needs to be welded, firstly, the two ends of the template are placed inside the load-bearing plate 406, then the load-bearing plate 406 is moved, and during the movement of the load-bearing plate 406, the positioning rod 407 connected thereto also moves accordingly, and the movement of the positioning rod 407 drives the slider 403 to slide on the inner wall of the connecting plate 401, and at the same time, the sliding of the positioning rod 407 also causes the first spring 408 and the pushing rod 404 to be displaced, thereby pushing the first sliding rod 405 and the pressing plate 402 to move synchronously, and when the load-bearing plate 406 moves into position, After that, the load-bearing plate 406 is pressed to make it approach the connecting plate 401. During this process, the first spring 408 is squeezed and begins to shrink. The shrinking spring will apply a thrust to the push rod 404, and the push rod 404 will slide along the positioning rod 407 and the second sliding rod 506 toward the connecting plate 401. When the push rod 404 slides a certain distance and contacts with the connecting plate 401, the load-bearing plate 406 is firmly fixed with the help of the pushing force of the pressing plate 402 and the first spring 408, thereby ensuring that the template can be quickly fixed and facilitating subsequent movement operations.

[0035] Example 2: Please refer to Figure 6-Figure 7On the basis of the first embodiment, the present invention provides a technical solution: it also includes a rotating mechanism 5, which includes a bottom plate 501, a telescopic rod 502 is fixedly connected to the side of the bottom plate 501 close to the moving mechanism 4, and a clamping plate 503 is rotatably connected to the side of the telescopic rod 502 away from the bottom plate 501 through a first rotating shaft, and an arc rod 504 is fixedly connected to the outer wall of the clamping plate 503, and a second sliding rod 506 is fixedly connected to the side of the arc rod 504 away from the clamping plate 503, and the clamping plate 503 is used to drive the arc rod 504 to rotate, and a clamping plate 505 is provided on the outer wall of the second sliding rod 506, and the inner wall of the clamping plate 505 is slidably connected to the outer wall of the second sliding rod 506, and a second spring 507 is fixedly connected to the bottom of the side of the clamping plate 505 away from the arc rod 504, and the second spring 507 contacts the outer wall of the second sliding rod 506, and the second spring 507 is used to pull the clamping plate 505 to fit together, and the arc rod 504 and the clamping plate 505 The pull rope 508 is arranged to pull the insertion rod 509 to move the card plate 503.

[0036] The working principle of this embodiment is as follows: when the left and right sides of the template pass through the inner wall of the load-bearing plate 406, they will come into contact with the clamping plate 505. As the template continues to squeeze the clamping plate 505, the clamping plate 505 will slide along the second slide bar 506. During this process, the movement of the clamping plate 505 will stretch the second spring 507 until the clamping plate 505 is completely fitted with the template. The clamping plate 505 will stop moving. At this time, the template is firmly fixed by the clamping plate 505. When the template needs to be rotated during welding, the clamping plate 503 is rotated. 503 drives the arc rod 504 to rotate synchronously, and the arc rod 504 further drives the second slide bar 506 to tilt. When the second slide bar 506 tilts, it will pull the clamp plate 505 to rotate accordingly, thereby realizing the adjustment of the template angle. When the card plate 503 rotates, its notch will align with the insertion rod 509. At this time, with the help of the pulling force of the pull rope 508, the insertion rod 509 is moved and embedded in the notch of the card plate 503, thereby completing the fixation of the rotation position of the card plate 503 and ensuring that the template remains stable at the adjusted angle.

[0037] Example 3: Please refer to Figure 8 On the basis of the first and second embodiments, the present invention provides a technical solution: it also includes a clamping mechanism 6, the clamping mechanism 6 includes a motor 601, the side of the motor 601 close to the fixed plate 2 is fixedly connected to the fixed plate 2, the output end of the motor 601 passes through the fixed plate 2, the output end of the motor 601 is rotatably connected to the connecting plate 401 through a bearing, the motor 601 is used to drive the clamping mechanism 6 to rotate, the side of the output end of the motor 601 away from the connecting plate 401 is fixedly connected to a fixing ring 602, the top of the fixing ring 602 is fixedly connected to a connecting rod 604, the side of the connecting rod 604 away from the fixing ring 602 is rotatably connected to a rotating plate 605 through a second rotating shaft, and the side of the connecting rod 604 close to the output end of the motor 601 is fixedly connected to the fixing ring 602, and the fixing ring 602 is fixedly connected to the top of the fixing ring 602. An elastic plate 603 is fixedly connected, and the elastic plate 603 is used to fix the template again. An elastic rope 606 is fixedly connected to the bottom of the elastic plate 603 close to the rotating plate 605. By setting the elastic rope 606, the rotating plate 605 can be pulled so that the rotating plate 605 is always in a fixed state with respect to the template, thereby ensuring that the template is also in a fixed state when the angle is rotated. The side of the elastic rope 606 away from the elastic plate 603 is fixedly connected to the rotating plate 605. The connecting rod 604, the rotating plate 605, the elastic rope 606 and the elastic plate 603 are arranged in two groups and are symmetrically arranged with the middle part of the fixing ring 602 as the center. The elastic rope 606 is used to pull the rotating plate 605 to move closer to the elastic plate 603.

[0038] The working principle of this embodiment is as follows: when the template contacts the clamping mechanism 6, it will first touch the rotating plate 605. Under the pushing action of the template, the rotating plate 605 rotates outward and opens, and the template immediately begins to slide into the inside of the clamping mechanism 6 along the guide of the rotating plate 605. At the same time, the elastic rope 606 is stretched, and the template contacts the elastic plate 603 and applies a thrust to it, causing the elastic plate 603 to expand and deform outward. In this way, the template can fit tightly and completely with the elastic plate 603. Thereafter, the elastic plate 603 rebounds inwardly by its own elastic restoring force, pulling the elastic rope 606 back. When the elastic rope 606 shrinks, it will pull the rotating plate 605 to rotate back to the initial position, thereby further stabilizing the template. When the angle of the template needs to be adjusted, the motor 601 is started, and the motor 601 drives the relevant components to rotate until the template rotates to the required precise angle. Under the coordinated clamping action of the elastic plate 603 and the rotating plate 605, the template will not have position deviation during the rotation process and after it is rotated into place, so that better welding can be performed.
