[0023] Example:

[0024] Reference Figure 1-Figure 4As shown, this embodiment proposes an adjustable quick clamping mechanism for mold customization processing, which is arranged on the peripheral side of a feeding mechanism 1. A mold body 2 is transported on the feeding mechanism 1, including a driving part, a pair of first abutting parts 7 and a pair of second abutting parts 14. The first abutting part 7 has a displacement space perpendicular to the stroke direction of the driving part. The second abutting part 14 is connected to the driving part and pushes the mold body 2 to move until it is abutted and fixed with the first abutting part 7. A linkage component is provided at a set distance from the first abutting part 7 to one side of the driving part. The linkage component is suitable for adjusting the distance between the pair of first abutting parts 7. The second abutting part 14 pushes the small-sized mold body 2 to move until the inner side of the mold body 2 reaches a distance inside the outermost end of the first abutting part 7. The driving part acts on the linkage component to make the pair of first abutting parts 7 approach each other. When the mold body 2 continues to move inward, it is released and abutted with the first abutting part 7. What this embodiment achieves is that when clamping the mold body 2 of different specifications and sizes, through the setting of the linkage component, the mold body 2 of smaller size may not form abutment with the first abutment part 7 after passing a distance from the outermost end of the first abutment part 7. If the initial size of the mold body 2 is less than the minimum initial distance between a pair of abutment parts, then the first abutment part 7 and the second abutment part 14 cannot form a clamping effect on the mold body 2; in order to prevent this situation, after the mold body 2 moves a distance toward the first abutment part 7, the mold body 2 will act on the linkage component to make the pair of abutment parts close to each other, and at this time, it can adapt to the clamping of the mold body 2 of smaller specifications. Through the above scheme, when the mold body 2 is larger, it can be clamped and fixed directly between the first abutment part 7 and the second abutment part 14. When the mold body 2 is smaller, after the mold body 2 is pushed to a certain distance, the driving part will cooperate with the linkage component to reduce the distance between the pair of first abutment parts, thereby adapting to the clamping of the mold body 2, thereby realizing automatic adjustment according to the mold body 2 of different specifications.

[0025] Specifically, the linkage assembly is configured as an articulated link assembly 9, which includes a first articulated portion, a second articulated portion, and two movable slide grooves 11 that respectively move the first articulated portion laterally and the second articulated portion longitudinally, and a paddle 10 is provided at the second articulated portion, and a driving portion is provided with a linkage rod 6, and the abutment portion is connected to the first articulated portion, and at the same time, the articulated link assembly 9 is symmetrically provided with two corresponding abutment portions. When the driving portion drives the mold body 2 to clamp, the driving portion causes the linkage rod 6 to move toward the paddle 10, and when the mold body 2 enters the outermost end of the first abutment portion 7 for a distance and does not form an abutment, the mold body 2 continues to move, allowing the linkage rod 6 to act on the paddle 10, thereby causing the second articulated portion to move away from the first abutment portion 7, so that the first articulated portion is close to the center of the pair of abutment portions, so that the pair of first articulated portions are close to each other, thereby completing the purpose of supporting the mold body 2. The distance between the linkage rod 6 and the paddle 10 determines that the mold body 2 starts to act on the paddle 10 after moving to a “certain distance” from the first abutting portion 7 , so that the pair of first abutting portions 7 approach each other.

[0026] In fact, Figure 3 As shown, the second hinged portion (the end connected to the paddle 10) actually has a movable slot at the bottom, and the movable slot connected to the first hinged portion (the end connected to the slider 12 or the first abutting portion 7) can be a sliding plate with a transverse slot provided on the sliding plate.

[0027] Reference Figure 1 , Figure 3 As shown, the adjustable quick clamping mechanism for customized mold processing also includes an L-shaped main board 8 for mounting the driving part and the first abutting part 7. The driving part is mounted on the outer side of the vertical end 15 of the L-shaped main board 8, and the driving part is preferably configured as a cylinder; an avoidance groove 16 (such as Figure 1 , Figure 4 As shown in the figure, the top surface of the horizontal end of the L-shaped main board 8 is in the same height as the feeding plane of the feeding mechanism 1, so that the mold body 2 can directly fall into the top surface of the horizontal end of the L-shaped main board 8 for support. The piston rod of the cylinder passes through the vertical end 15 of the L-shaped main board 8 and is provided with an extension rod 13. The top of the connecting rod 6 is connected to the extension rod 13. The bottom of the connecting rod 6 passes through the avoidance groove 16 and is connected to the avoidance rod 3. The avoidance rod 3 bypasses the bottom of the feeding mechanism 1 and forms a U-shaped structure. The top of the avoidance rod 3 is connected to the second abutment portion 14. Such a setting, referring to Figure 1 When the part of the avoidance rod 3 on the right side moves to the left side, it will not interfere with the feeding mechanism 1, and it will not occupy too much space. In order to enhance the stability of the avoidance rod 3, a stopper with a hole can be fixedly set at the bottom of the vertical end 15 of the L-shaped main board 8 (refer to Figure 1 The left side of the avoidance rod 3 is inserted into the hole of the limiting part to ensure the stability of the avoidance rod 3 when it moves.

[0028] Reference Figure 1 and Figure 3 A reset portion 5 is fixedly installed at the end of the extension rod 13. In the initial state, the reset portion 5 is located within the conveying range of the feeding mechanism 1; when the mold body 2 passes through the second abutment portion 14, the driving portion is started and the second abutment portion 14 pushes the mold body 2 toward the first abutment portion 7; to prevent the reset portion 5 from interfering with the first abutment portion 7, the width of the reset portion 5 does not exceed the width of the avoidance groove 16; after clamping and processing the mold body 2, the driving portion drives the second abutment portion 14 to reset, and at the same time the reset portion 5 is reset along with the extension rod 13, so that the mold body 2 is reset to within the conveying range of the feeding mechanism 1, and the reset portion 5 resets the mold body 2 by utilizing the reset of the driving portion, which is reasonably designed and does not occupy additional space and does not require additional driving components.

[0029] Reference Figure 3 The bottom of the first hinged portion is connected to a slider 12, which is connected to the first abutting portion 7. A pair of sliders 12 are provided with return springs between the avoidance groove 16, which can be as follows Figure 3 As shown, Figure 3 A fixed block is also provided at the edge of the avoidance groove 16, and the fixed block is fixedly connected to the other end of the reset spring. After the connecting rod 6 pushes the paddle 10 and moves the abutting part, the mold body 2 is pushed to reset by the reset part 5, and the reset spring is reset to reset the slider 12 and the first hinge part, thereby resetting the second hinge part and the paddle 10.

[0030] Refer to the figure Figure 2 , Figure 3 and Figure 4 The first abutting portion 7 and the second abutting portion 14 have the same shape, and their cross sections are both right-angled trapezoids, and the four inclined surfaces of a pair of first abutting portions 7 and a pair of second abutting portions 14 form abutting surfaces that are connected to the mold body 2. Of course, the cross sections of the first abutting portion 7 and the second abutting portion 14 can also be set to reasonable shapes such as triangles.

[0031] Reference Figure 1 , Figure 2 A push plate 4 is fixedly installed on the back of a pair of second abutting portions 14, and the push plate 4 is fixedly connected to the avoidance rod 3; when the mold body 2 is narrow, the push plate 4 can push the mold body 2 to move and form an abutment clamp with the first abutting portion 7.
