Technical Field
[0001] This utility model relates to the field of automatic assembly of mold guide pillars, and in particular to an automatic assembly unit for precision mold guide pillars. Background Technology
[0002] In the automatic assembly process of molds and guide pillars, press fitting machines play a crucial role. Traditional guide pillar assembly often relies on manual operation, which is easily affected by human factors, leading to accuracy deviations and low efficiency. With the development of industrial automation, press fitting machines have become one of the key pieces of equipment for improving assembly accuracy and production efficiency. Through precise pressure and displacement control, press fitting machines ensure that guide pillars can be quickly and accurately embedded in the mold, avoiding product defects caused by uneven force or improper assembly.
[0003] Existing technologies, such as the utility model patent with publication number CN208374679U, disclose a press-fitting machine. This patent includes a frame, with a nut tightening device at the top of the frame. The nut tightening device is connected to a lifting cylinder and a parallel moving cylinder installed orthogonally to each other. A pressure cylinder is mounted on the base plate of the frame, installed vertically with its movable end facing upwards. A double press-fitting frame is also provided at the end of the movable rod of the pressure cylinder, and a positioning clamp is provided on the double press-fitting frame. Applying this solution allows for the mechanized completion of the press-fitting process, which is beneficial for improving the level of automation in production.
[0004] In the existing technology, when using a press machine to assemble guide pillars and molds, the operator must first place the mold on the press machine's worktable and insert the guide pillar into the mold's pre-drilled hole. During this process, the operator must hold the mold with their hand to prevent it from shifting, thereby ensuring the mold's stability. When the press machine reaches the preset pressing depth, the operator releases their hand. However, this operation method is not only unsafe and cumbersome, but also affects the assembly efficiency. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0031] Please see Figures 1 to 5 The present invention provides an automatic assembly unit for precision mold guide pillars, comprising: a press machine 1, a pressure plate 5, and an auxiliary structure 7. A control button 2 is installed on one side of the press machine 1, an electric push rod 3 is installed on the inner wall of the press machine 1, a push plate 4 is installed at the output end of the electric push rod 3, and the pressure plate 5 is fixed on the lower surface of the push plate 4 by means of the auxiliary structure 7. An adjustment structure 6 is provided on the inner wall of the press machine 1, and the auxiliary structure 7 is provided on the lower surface of the push plate 4.
[0032] In the embodiments of this utility model, please refer to Figures 2 to 4The adjusting structure 6 includes a fixed plate 601, which is fixedly connected to the press-fitting machine 1. Two connecting grooves 602 are formed on the upper surface of the fixed plate 601. Two positioning blocks 603 are slidably connected to the inner walls of each of the two connecting grooves 602. The two positioning blocks 603 form a group. A single positioning plate 604 is fixedly connected to the upper surface of each group of positioning blocks 603. An auxiliary plate 605 is fixedly connected to one side of the positioning plate 604, and a connecting frame 606 is fixedly connected to one side of the auxiliary plate 605. Gear 607 is rotatably connected to the inner wall of 06. Two telescopic rods 608 are fixedly connected to one side of the auxiliary plate 605. One end of the two telescopic rods 608 is fixedly connected to the same clamping plate 609. Springs 610 are sleeved on the arc surface of the telescopic rods 608. The two ends of the springs 610 are fixedly connected to the clamping plate 609 and the auxiliary plate 605 respectively. Several clamping blocks 611 are fixedly connected to one side of the clamping plate 609. Handrail 612 is fixedly connected to the other side of the clamping plate 609. A rack 613 is fixedly connected to one side of the fixed plate 601. The rack 613 meshes with the gear 607. The mold can be positioned by setting the adjustment structure 6, making the assembly process of the guide pillar and the mold more stable and safe. It avoids the need for manual support during the assembly process of the guide pillar and the mold, which not only improves safety but also improves assembly efficiency. A soft pad 614 is fixedly connected to one side of the positioning plate 604. The soft pad 614 is a rubber pad. The soft pad 614 can prevent the positioning plate 604 from directly contacting the mold and prevent the mold from wearing. The phenomenon is that a limiting rod 615 is fixedly connected to the inner wall of the connecting groove 602. The limiting rod 615 and the positioning block 603 are slidably connected. The limiting rod 615 can limit the positioning block 603, so that the positioning block 603 will not deviate during the movement. Roller balls 616 are fixedly connected to both sides of the positioning block 603. The cross-section of the roller balls 616 is circular. The roller balls 616 can reduce the friction of the positioning block 603, so that the positioning block 603 moves more smoothly in the connecting groove 602.
[0033] In the embodiments of this utility model, please refer to Figure 5The auxiliary structure 7 includes a fixing block 701, which is fixedly connected to a push plate 4. A screw 702 is threaded onto the inner wall of the fixing block 701. One end of the screw 702 is fixedly connected to a connecting plate 703, and the other end of the screw 702 is rotatably connected to a fixing frame 704. Two limiting frames 705 are fixedly connected to the lower surface of the push plate 4, and the limiting frames 705 and the fixing frame 704 are slidably connected. Several fixing rods 708 are fixedly connected to the lower surface of the push plate 4. Each of the arc surfaces of the fixing rods 708 is slidably connected to a limiting ring 707. The limiting rings 707 are fixedly connected to a pressure plate 5. Fixing frames 706 are fixedly connected to both sides of the pressure plate 5. The frame 704 is slidably connected. The auxiliary structure 7 allows for easy installation or removal of the pressure plate 5, preventing wear and tear on the pressure plate 5 during prolonged use and ensuring a more stable assembly between the guide post and the mold. The arc surface of the connecting plate 703 is provided with anti-slip textures 709, which are evenly distributed on the connecting plate 703. These textures increase the friction of the connecting plate 703, preventing slippage of the hands when rotating the connecting plate 703. Guide blocks 710 are fixedly connected to both sides of the fixed frame 704. Due to the small size of the guide blocks 710, the fixed frame 704 can be better inserted into the fixed frame 706.
[0034] The working principle of the precision mold guide post automatic assembly unit provided by this utility model is as follows: By setting the adjustment structure 6, the mold is first placed on the fixed plate 601. Then, the handle 612 is pulled to move the clamping plate 609, causing the clamping plate 609 to separate the clamping block 611 from the gear 607. During the movement, the clamping plate 609 will drive the spring 610 and the telescopic rod 608 to stretch. Then, the auxiliary plate 605 is moved to move the positioning plate 604. The positioning plate 604 drives the positioning block 603 to move in the connecting groove 602 of the fixed plate 601. At the same time, the auxiliary plate 605 will also drive the gear 607 in the connecting frame 606 to rotate on the rack 613. Then, the above steps are repeated so that the two positioning plates 604 clamp the mold. Then, the handle 612 is released. When released, spring 610 will drive the clamping plate 609 to move, so that the clamping block 611 on the clamping plate 609 will engage with the inside of the rack 613. At this time, the fixing is completed. Then, the guide post is inserted into the reserved hole of the mold. Then, press the control button 2 to start the electric push rod 3 in the press machine 1, so that the electric push rod 3 drives the push plate 4 to move. The push plate 4 drives the pressure plate 5 to move, so that the pressure plate 5 assembles the guide post and the mold. Among them, the soft pad 614 can prevent the positioning plate 604 from directly contacting the mold, preventing the mold from being worn. The limit rod 615 can limit the positioning block 603, so that the positioning block 603 will not deviate during the movement. The ball 616 can reduce the friction of the positioning block 603, so that the positioning block 603 moves more smoothly in the connecting groove 602.
[0035] By setting the auxiliary structure 7, the pressure plate 5 is first moved to drive the limiting ring 707 to move, so that the limiting ring 707 is inserted into the fixing rod 708 under the push plate 4. Then, with the help of the anti-slip texture 709, the connecting plate 703 is rotated, so that the connecting plate 703 drives the screw 702 to rotate inside the fixing block 701. The screw 702 then drives the fixing frame 704 to move inside the limiting frame 705, so that the fixing frame 704 is inserted into the fixing frame 706. At this time, the fixing of the pressure plate 5 is completed. The anti-slip texture 709 can increase the friction of the connecting plate 703 and prevent the personnel from slipping their hands when rotating the connecting plate 703. Since the guide block 710 is small in size, it can better insert the fixing frame 704 into the fixing frame 706.
[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
