[0028] Example 1

[0029] An injection molding machine that facilitates mold disassembly, see Figure 1-Figure 5 As shown, it includes an injection molding machine 1, a first cylinder 2, a mold 3, a mounting plate 4, a fixing plate 11, a fixing mechanism 5, a clamping mechanism 6 and a lifting mechanism 7. A fixing plate 11 is welded to the front side of the upper portion of the injection molding machine 1, and the first cylinder 2 is bolted to the fixing plate 11. Two mounting plates 4 are connected to the front side of the upper portion of the injection molding machine 1. The mounting plates 4 are located behind the fixing plates 11. The front mounting plate 4 is slidably connected to the injection molding machine 1, and the rear mounting plate 4 is fixedly connected to the injection molding machine 1. The rear side of the telescopic rod of the first cylinder 2 is connected to the front mounting plate 4. The mold 3 is installed on the sides of the two mounting plates 4 that are close to each other. The fixing mechanism 5 is arranged on the mounting plate 4, the clamping mechanism 6 is arranged on the mounting plate 4, and the lifting mechanism 7 is arranged on the mold 3.

[0030] See also Figure 1-Figure 3As shown, the fixing mechanism 5 includes a gear box 51, a guide rod 52, a screw 53 and a motor 54. Four guide rods 52 are connected at intervals on the sides of the two mounting plates 4 that are away from each other. The gear box 51 is slidably arranged between the four guide rods 52 on the front side, and the gear box 51 is also slidably arranged between the four guide rods 52 on the rear side. Motors 54 are bolted to the right sides of the upper parts of the two gear boxes 51. The output shafts of the two motors 54 are respectively connected to the input ends of the adjacent gear boxes 51. Four screws 53 are connected to the output ends of the two gear boxes 51. The screws 53 are distributed in a rectangular shape. The screws 53 are threadedly connected to the mounting plate 4 and the mold 3. The output shafts of the two motors 54 are connected to the adjacent screws 53. The output shafts of the motors 54 rotate forward through the gear box 51 to drive the screws 53 to rotate forward, so that the screws 53 move outward and separate from the mold 3.

[0031] See also Figure 1 and Figure 4 As shown, the clamping mechanism 6 includes a second cylinder 61, a first clamping plate 62 and a second clamping plate 63. The second cylinder 61 is symmetrically bolted to the front side of the rear mounting plate 4. The first clamping plate 62 is connected to the side of the telescopic rod of the second cylinder 61 that is close to each other. The second clamping plate 63 is slidably arranged on the two first clamping plates 62. The second clamping plate 63 is slidably connected to the rear mounting plate 4. The second clamping plate 63 is located in front of the first clamping plate 62. The rear mold 3 is located between the two first clamping plates 62. The first clamping plate 62 and the second clamping plate 63 are both L-shaped. Soft pads are arranged on the inner sides of the first clamping plate 62 and the second clamping plate 63. The first clamping plate 62 and the second clamping plate 63 move inward to limit the mold 3.

[0032] See also Figure 1 and Figure 5 As shown, the lifting mechanism 7 includes a rotating shaft 71, a hanging ring 72, a full gear 73, a volute spring 74 and a contact block 75. The upper part of the two molds 3 is rotatably provided with a rotating shaft 71, and the middle part of the two rotating shafts 71 is welded with a hanging ring 72. The rotation of the rotating shaft 71 will drive the hanging ring 72 to rotate upward, and then people can hang the hook of the crane on the hanging ring 72, and then lift the mold 3 by the crane. The left side of the two rotating shafts 71 is connected with a full gear 73, and the right side of the bottom of the front rotating shaft 71 is connected with a contact block 75. The second clamping plate 63 on the right side moves forward and contacts with the contact block 75. A volute spring 74 is connected between the front rotating shaft 71 and the front mold 3.

[0033] When the device is needed, people first place the device in the designated position, then start the first cylinder 2, control the extension of the telescopic rod of the first cylinder 2, drive the front mounting plate 4 and the mold 3 to move backward, the front mounting plate 4 moves backward and drives the front gear box 51 to move backward, so that the front mold 3 fits with the rear mold 3, and the two full gears 73 mesh with each other, and then close the first cylinder 2, and then pull the second clamping plate 63 forward, so that the two second clamping plates 63 are respectively located on the left and right sides of the front mold 3, and at the same time, the second clamping plate 63 on the right side moves forward and contacts with the contact block 75, and the second clamping plate 63 squeezes the contact block 75 to rotate upward, and the contact block 75 rotates upward to drive the front rotating shaft 71 to rotate, and the volute spring 74 is deformed, and the front rotating shaft 71 can drive the rear rotating shaft 71 to rotate through the meshing of the full gear 73, and the rotating shaft 71 drives the hanging ring 72 to rotate upward, and then start the second cylinder 61, control the second cylinder The telescopic rod 61 is extended, driving the first clamping plate 62 and the second clamping plate 63 to move inward, so that the mold 3 can be limited by the first clamping plate 62 and the second clamping plate 63, and then the second cylinder 61 is closed, and then people start the motor 54 and control the output shaft of the motor 54 to rotate forward. The forward rotation of the output shaft of the motor 54 drives the screw 53 to rotate forward through the gear box 51, so that the screw 53 moves outward, and the screw 53 moves outward and drives the gear box 51 to move outward. The guide rod 52 plays a guiding role. When the screw 53 is separated from the mold 3, the motor 54 is turned off, and people can hang the hook of the crane on the hanging ring 72, and pull the mold 3 up by the crane, so that the mold 3 rises up, thereby completing the disassembly of the mold 3, and then start the second cylinder 61, control the telescopic rod of the second cylinder 61 to shorten, drive the first clamping plate 62 and the second clamping plate 63 to move outward and reset, and then close the second cylinder 61, and then push the second clamping plate 63 to the rear side to reset.

[0034] Example 2

[0035] Based on Example 1, see Figure 1 and Figure 6 As shown, a locking mechanism 8 is also included, and the locking mechanism 8 includes a slide plate 81, a first elastic member 82, a clamping block 83 and a second elastic member 84. The left and right sides of the rear mold 3 are symmetrically slidably arranged with slide plates 81, and the front side of the second clamping plate 63 is in contact with the slide plate 81. The first elastic member 82 is connected between the rear sides of the four slide plates 81 and the rear mold 3. The left and right sides of the front mold 3 are symmetrically slidably arranged with clamping blocks 83. The clamping blocks 83 can be moved outward to clamp the slide plate 81, thereby fixing the two molds 3 to prevent the two molds 3 from shaking. The second elastic member 84 is connected between the side where the four clamping blocks 83 are close to each other and the front mold 3.

[0036] When people pull the second clamping plate 63 forward, the second clamping plate 63 will squeeze the slide plate 81 to move forward, and the first elastic member 82 will be stretched. When the slide plate 81 contacts the block 83, the slide plate 81 will squeeze the block 83 to move inward, and the second elastic member 84 will be compressed. When the slide plate 81 passes over the block 83, the second elastic member 84 will return to its original state, driving the block 83 to move outward and reset. The block 83 can clamp the slide plate 81, thereby fixing the two molds 3. When the molds 3 rise upward, the two molds 3 can be prevented from shaking. When the two molds 3 need to be removed, people first push the slide plate 81 backward. The slide plate 81 will squeeze the block 83 to move inward, and the second elastic member 84 will be compressed. When the slide plate 81 passes over the block 83, the second elastic member 84 will return to its original state, driving the block 83 to move outward and reset. At the same time, the first elastic member 82 will return to its original state, driving the slide plate 81 to move backward and reset, so that the slide plate 81 releases the mold 3.

[0037] See also Figure 1 and Figure 7 As shown, it also includes a guide mechanism 10, which includes a guide plate 101 and a magnet 102. The two first clamps 62 are slidably provided with a guide plate 101 on one side close to each other, and the two second clamps 63 are slidably provided with a guide plate 101 on one side close to each other. The upper parts of the four guide plates 101 on one side close to each other are connected to the magnet 102. The upward movement of the mold 3 will drive the magnet 102 and the guide plate 101 to move upward. The guide plate 101 plays a guiding role, thereby preventing the mold 3 from shaking.

[0038] When the first clamping plate 62 and the second clamping plate 63 move inward, they will drive the guide plate 101 and the magnet 102 to move inward, so that the magnet 102 attracts the mold 3. When the mold 3 moves upward, it will drive the magnet 102 to move upward. The upward movement of the magnet 102 drives the guide plate 101 to move upward. The guide plate 101 plays a guiding role, thereby preventing the mold 3 from shaking. When the mold 3 continues to move upward and separates from the magnet 102, under the action of gravity, the guide plate 101 can move downward and reset, driving the magnet 102 to move downward and reset.

[0039] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
