[0036] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] This utility model embodiment specifically provides a quick mold change machine; please refer to... Figures 1-6 The system includes a workbench 1, on which an injection molding assembly 11 is installed. The bottom of the workbench 1 is provided with a mold changing chamber 12 with an open front side. The injection molding assembly 11 is an existing mature component used to inject thermoplastic raw materials into the mold 7 for forming operations.

[0038] Furthermore, the mold changing machine also includes a conversion component 2 installed in the mold changing chamber 12. The upper surface of the worktable 1 is provided with a mold changing port 13 that communicates with the mold changing chamber 12, through which different types of molds 7 are changed.

[0039] The conversion component 2 includes a first moving part 3, a driving component 4, a guide frame 5, and a second moving part 6. The first moving part 3 is disposed inside the mold changing chamber 12. The driving component 4 is used to drive the first moving part 3 to move up and down. The guide frame 5 is fixedly installed inside the mold changing chamber 12. The second moving part 6 is slidably installed on the guide frame 5. The first moving part 3 and the second moving part 6 are used to install the mold 7 in a detachable manner.

[0040] Specifically, the first moving part 3 includes a first support 31, and a first locking post 32 is fixedly installed on the upper surface of the first support 31. The number of first locking posts 32 is set to two or more, so as to facilitate subsequent connection with the mold 7.

[0041] The guide frame 5 is parallel to the length of the workbench 1. The second moving part 6 includes a second support 61 that is slidably mounted on the guide frame 5. The upper surface of the second support 61 is provided with a placement groove 62. A second locking post 63 is fixedly mounted on the placement groove 62 to provide installation space for the mold 7.

[0042] During implementation, the bottom end of the mold 7 abuts against the support 31 and the placement groove 62, and the bottom surface of the mold 7 is provided with a first slot 71 and a second slot 72 for insertion with the first locking post 32 and the second locking post 63, so that when the mold 7 is connected to the first support 31 or the second support 61, it can maintain horizontal locking through the connection between the locking post and the slot, thereby improving the stability of movement.

[0043] It is worth noting that mold 7 is a commonly used mold structure in the prior art. When implementing it, it is only necessary to open a slot at the bottom to meet the requirements of this technical solution.

[0044] Furthermore, the side of the guide frame 5 closest to the second moving member 6 is open, and a slide bar 51 is integrally fixed on the inner side of the guide frame 5. A groove 64 for sliding along the slide bar 51 is opened on the outer side of the second support 61. The slide bar 51 and the groove 64 are kept parallel, so that the second support 61 can move stably along the slide bar 51 through the groove 64. At the same time, the movement mode of the second support 61 can be restricted, so that the second support 61 can only slide left and right along the guide frame 5, so as to provide stable and reliable support for the placement of the mold 7.

[0045] In practice, the guide frame 5, the second moving part 6, and the first moving part 3 of the same height form a set of mold changing structure. There are three mold changing structures along the height direction of the mold changing chamber 12. Each mold changing structure is used to place a mold 7 with a mold cavity structure. The internal mold cavity structures of the three sets of molds 7 are different, which facilitates the forming of different objects and enables quick mold changing when it is necessary to switch the processing of object types.

[0046] The first moving part 3 can quickly separate the molds 7 on the three mold changing structures from the second moving part 6 and transport them upward, so that the molds 7 can be raised from the mold changing port 13 to cooperate with the injection molding assembly 11 for production.

[0047] Among them, a baffle 8 is fixedly installed on the inner wall of the mold changing chamber 12 in the area that matches the height of each mold changing structure. There are also three baffles 8. The baffles 8 are used to abut against the outer side of the second support 61, so that when the second support 61 moves the mold 7 to below the mold changing port 13 and aligns it, it can be intercepted by the baffles 8. The setting position of the baffles 8 can be set according to the limit movement stroke position of the second support 61 below the mold changing port 13 during actual use, so that the second support 61 can move the mold 7 accurately to below the mold changing port 13.

[0048] The second support 61 has a through groove in the middle. The through groove is open in the direction close to the first support 31, and the size of the through groove is larger than that of the first support 31. This allows the mold 7 to move from the second support 61 to below the mold changing port 13. The first support 31 moves upward, allowing the first locking post 31 to engage with the first locking groove 71. The mold 7 is then moved upward from the second support 61 and rises from the mold changing port 13 for injection molding.

[0049] Furthermore, a lifting groove 14 is provided on the outer side of the workbench 1. The drive assembly 4 includes a slider 41 that is slidably connected along the lifting groove 14, a synchronous seat 42 that is fixedly connected to the outer side of the slider 41, a motor 44 that is threadedly connected to the outer side of the synchronous seat 42 and the lead screw 43, and whose output shaft is fixed to the lead screw 43. The slider 41 is fixedly connected to the outer side of the first support 31, so that the movement of the slider 41 drives the first support 31 to move up and down.

[0050] In practice, the motor 44 drives the lead screw 43 to rotate, thereby enabling the lead screw 43 to drive the synchronous seat 42 and the slider 41 to move up and down, thus controlling the up and down displacement of the first support 31.

[0051] The motor 44 is fixed to the workbench 1 via a motor mount 45. The motor mount 45 is fixedly installed on the placement surface or the outside of the workbench 1 to provide stable installation and operation for the motor 44.

[0052] By adopting the above technical solution, there are three different molds 7. When it is necessary to switch molds 7, the first support 31 can be moved down first, so that the mold 7 falls onto the previously separated second support 6, and the first support 31 can continue to move down until it is at the bottom of the mold changing structure. Then, the mold 7 to be replaced can be manually pushed to the right by the second support 6 to reset. Then, the mold 7 to be replaced can be manually pushed by the worker to move the second support 61 to the bottom of the mold changing port 13, and the first support 31 can be moved up to connect with the mold 7 and continue to move up, so that it can be removed from the mold changing port 13 for use.

[0053] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
