Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: a quick-change injection mold structure, including an extrusion plate 1, with multiple sliding sleeves embedded in the extrusion plate 1, and anti-deviation rods 5 slidably connected within the sliding sleeves. One end of each anti-deviation rod 5 is connected to the same fixed plate 2. Installation grooves 10 are provided on one side of the extrusion plate 1 and one side of the fixed plate 2. A first mold 3 and a second mold 4 are respectively installed in the two installation grooves 10. Installation and removal devices 8 are provided on the inner walls of both installation grooves 10. The installation and removal devices 8 include two side grooves 811 and two movable grooves 802. Movable blocks 804 are slidably connected within the movable grooves 802. A snap-fit ​​block 810 is connected to one side of the movable block 804. A clearance groove 805 is provided on one side of the movable block 804. A first spring 808 is connected to one side of the clearance groove 805. A connecting block 803 is connected to one side of the movable block 804, and the same pull bracket 801 is connected to one side of each of the two connecting blocks 803. A snap-fit ​​groove 812 is provided on one side of the side grooves 811. A connecting groove 809 is provided on one side of the mounting groove 10. The movable groove 802 is provided on one side of the inner wall of the mounting groove 10. The snap-fit ​​block 810 has an inclined surface on one side and is inserted into the snap-fit ​​groove 812 on one side. Multiple side grooves 811 are provided on one side of the first mold 3 and the second mold 4. The other end of the first spring 808 is connected to one side of the inner wall of the movable groove 802. One side of the connecting block 803 extends out of the movable groove 802 through the connecting groove 809, and the outer wall of the connecting block 803 is slidably connected to the inner wall of the connecting groove 809. A fixing groove 806 is provided on one side of the inner wall of the allowance groove 805, and a fixing rod 807 is slidably connected in the fixing groove 806. The other end of the fixing rod 807 is connected to one side of the inner wall of the movable groove 802, and the first spring 808 is sleeved on the outside of the fixing rod 807. Sliding grooves 6 are provided on both sides of the inner wall of the mounting groove 10, and sliding blocks 7 are slidably connected in the sliding grooves 6. Multiple sliding blocks 7 are respectively connected to one side of the first mold 3 and the second mold 4 on one side.

[0029] In a specific implementation, by setting up the installation and removal device 8, pressing the pull bracket 801 causes the pull bracket 801 to move the connecting block 803 to one side. The connecting block 803 then moves the movable block 804, which in turn moves the locking block 810 to one side. This causes the locking block 810 to slide out of the locking groove 812, thus causing both locking blocks 810 to lose their fixing effect on the first mold 3 and the second mold 4. This allows the first mold 3 and the second mold 4 to be removed to one side, avoiding the need for bolt disassembly which would result in excessive operation time and reduced maintenance efficiency. During installation, pressing the first mold 3 and the second mold 4 causes the side groove 811 on one side of the first mold 3 and the second mold 4 to press against the inclined surface on one side of the locking block 810, causing the locking block 810 to move to one side. The compression causes the first spring 808 to contract. After the first mold 3 and the second mold 4 are installed in place, the snap-fit ​​block 810 is reset and moved by the rebound force of the first spring 808, so that the snap-fit ​​block 810 is inserted into the snap-fit ​​groove 812 to fix the first mold 3 and the second mold 4, thereby improving the installation efficiency. The first spring 808 is supported by the fixing rod 807 to prevent the first spring 808 from bending during compression and affecting the rebound effect of the first spring 808. The first mold 3 and the second mold 4 are placed in the drive module, and the drive module is equipped with a drive hydraulic cylinder, so that the hydraulic cylinder drives the extrusion plate 1 to move, and the extrusion plate 1 drives the second mold 4 to move, so that the second mold 4 fits with the first mold 3. This technology is prior art and does not need to be described in detail.

[0030] A protective device 9 is provided between the first mold 3 and the second mold 4. The protective device 9 includes a sliding groove 901 and a plug-in bracket 905. The sliding groove 901 is opened on one side of the first mold 3 and connected to it. A stop bracket 903 is slidably connected to the inner wall of the sliding groove 901. A plurality of second springs 904 are connected to one side of the stop bracket 903. The other end of the second spring 904 is connected to one side of the inner wall of the sliding groove 901. One side of the plug-in bracket 905 is connected to one side of the second mold 4. A plurality of support grooves are opened on one side of the inner wall of the sliding groove 901, and a support rod 902 is slidably connected in the support groove. The other end of the support rod 902 is connected to one side of the stop bracket 903, and the second spring 904 is sleeved on the outside of the support rod 902. After the first mold 3 and the second mold 4 are fitted together, the outer wall of the plug-in bracket 905 is inserted into and fitted into the sliding groove 901.

[0031] In a specific implementation, by setting up a protective device 9, after the second mold 4 is moved to fit against the first mold 3, the insertion bracket 905 on one side of the second mold 4 is inserted into the sliding groove 901 on one side of the first mold 3. The insertion bracket 905 presses against the abutment 903 on one side, causing the abutment 903 to move to one side and press against the second spring 904. The rebound force of the second spring 904 makes the abutment 903 and the insertion bracket 905 fit tightly together, thereby improving the sealing effect between the insertion bracket 905 and the sliding groove 901. The insertion bracket 905 blocks and seals the gap between the first mold 3 and the second mold 4, preventing the injection molding material from overflowing from the gap and causing damage to the surrounding area.

[0032] Working principle: During use, the extrusion plate 1 drives the second mold 4 to move, bringing the second mold 4 closer to and fitting with the first mold 3. The insertion bracket 905 on one side of the second mold 4 is inserted into the sliding groove 901, sealing the gap between the first mold 3 and the second mold 4 and preventing the injection molding material from overflowing from the gap and causing injury to surrounding personnel. When the first mold 3 and the second mold 4 need maintenance after long-term use, pressing the pull bracket 801 causes the pull bracket 801 to move the connecting block 803 to one side, which in turn causes the connecting bracket to move the movable block 804. The movable block 804 then moves the locking block 810, causing the locking block 810 to slide out of the locking groove 812. This causes the two locking blocks 810 to lose their fixing effect on the first mold 3 and the second mold 4, allowing the first mold 3 and the second mold 4 to be removed for maintenance. This reduces the disassembly operation of the first mold 3 and the second mold 4 and improves maintenance efficiency.
