[0014] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0015] Embodiment 1:

[0016] like Figure 1-Figure 4As shown, the utility model discloses a mold frame plate processing clamping device, including a base plate 1 and a baffle plate 2 arranged on one side of the base plate 1, the baffle plate 2 is arranged vertically upward, and a processing platform 3 is formed by bulging upward at the middle part of the base plate 1, the upper surface of the processing platform 3 is horizontal, the processing platform 3 and the baffle plate 2 are abutted against each other, and side clamping mechanisms are arranged on the base plate 1 at both ends of the processing platform 3, and the two side clamping mechanisms are used to clamp the mold frame plate, and a downwardly concave assembly cavity 4 is arranged on the processing platform 3 opposite to the front of the baffle plate 2, and a group of first slide rails 5 are arranged at the bottom of the assembly cavity 4, the first slide rails 5 are perpendicular to the front of the baffle plate 2, and a moving seat 6 is slidably arranged on the first slide rails 5, the moving seat 6 is a hollow structure with an opening upward, and a movable top block 7 is arranged in the moving seat 6, and the movable top block 7 is arranged on both sides away from one end of the baffle plate 2. A rotating shaft 8 is rotatably connected with the side wall of the movable seat 6, and a torsion spring 9 is sleeved on the rotating shaft 8. The two ends of the torsion spring 9 are respectively fixedly connected to the movable top block 7 and the side wall of the movable seat 6. A limiting shaft 11 is arranged on both sides of the movable top block 7 near one end of the baffle 2, and a limiting long hole 12 is arranged on the side wall of the movable seat 6 corresponding to the limiting shaft 11, and the limiting shaft 11 extends into the limiting long hole 12. Under the action of the torsion spring 9, when the movable top block 7 is in a natural state, the limiting shaft 11 is located at the uppermost end of the limiting long hole 12, and a part of the movable top block 7 is exposed above the movable seat 6 and the processing platform 3. A first hydraulic cylinder 10 is arranged in the assembly cavity 4 away from one end of the baffle 2, and the telescopic end of the first hydraulic cylinder 10 is connected to the movable seat 6, and the first hydraulic cylinder 10 drives the movable seat 6 to reciprocate on the first slide rail 5.

[0017] A processing platform 3 is formed by a protrusion in the middle of the bottom plate 1, and the upper surface of the processing platform 3 is in a horizontal state. The baffle 2 is located on one side of the bottom plate 1 and contacts the processing platform 3. The baffle 2 can locate the base plate on the processing platform 3 on the reference plane. The side clamping mechanisms on both sides can clamp and locate the two sides of the base plate to maintain the left and right positioning. In the actual processing process, when the base plate is initially placed on the processing platform 3, due to the baffle 2 at the rear, its position must be relatively forward, and it is very easy to interfere with the movable top block 7. In this application, a concave assembly cavity 4 is set on the processing platform 3 in front of the baffle 2, and the first slide rail 5 and the first hydraulic cylinder 10 are used to drive the movable seat 6 to move back and forth. The movable seat 6 is hollow inside, and the movable top block 7 is set in the movable seat 6, which is rotatably connected to the movable seat 6 through the rotating shaft 8, and the torsion spring 9 is used to cause the movable top block 7 to partially protrude from the processing platform 3 in a natural state. Therefore, when the mold plate is initially placed on the processing platform 3, even if it interferes with the mold plate, the movable top block 7 will be pressed into the inside of the moving seat 6, and will not cause damage to the mold plate. At this time, the staff can push the mold plate inward to disengage it from the movable top block 7. At this time, the movable top block 7 bounces upward under the action of the torsion spring 9. Due to the action of the limit long hole 12 and the limit shaft 11, the highest position of the movable top block 7 is limited. At this time, the movable top block 7 partially protrudes from the processing platform 3, and the side facing the baffle 2 is a vertical plane. Under the action of the first hydraulic cylinder 10, the moving seat 6 and the movable top block 7 are pushed forward to push the mold plate toward the baffle 2. At the same time, the side clamping mechanism is used to limit the left and right positions of the mold plate to achieve positioning on all sides with high positioning accuracy.

[0018] Of course, the hollow structure inside the movable seat 6 can accommodate the entire movable top block 7. In the natural state, the end of the movable top block 7 close to the baffle 2 is exposed above the processing platform 3, and the rotating shaft 8 is naturally located on the movable seat 6 below the processing platform 3. When the mold frame plate is pushed, the movable top block 7 close to the end of the baffle 2 is in contact with the mold frame plate. At this time, the movable top block 7 receives an upward thrust, and due to the action of the limit shaft 11 and the limit long hole 12, the movable top block 7 is kept in this position, so it can generate thrust on the mold frame plate and maintain a stable state, and the clamping of the mold frame plate is stable and reliable.

[0019] The position-limiting long hole 12 is an arc-shaped hole, and the center of the arc where the position-limiting long hole 12 is located coincides with the central axis of the rotating shaft 8. By adopting the arc-shaped position-limiting long hole 12, and its center coincides with the central axis of the rotating shaft 8, when the movable top block 7 rotates around the rotating shaft 8, the position-limiting shaft 11 can smoothly move around the rotating shaft 8 in the position-limiting long hole 12, so that the movable top block 7 can move smoothly as a whole, and the width of the position-limiting long hole 12 only needs to be the same as or slightly larger than the diameter of the rotating shaft 8, which can improve the strength of the movable seat 6.

[0020] The structure of the side clamping mechanism is as follows: a group of second slide rails 13 are respectively arranged on the bottom plates 1 at both ends of the processing platform 3, the second slide rails 13 are parallel to the baffle 2, and a side pressure block 14 is slidably connected to the second slide rails 13. The side pressure block 14 is L-shaped, and the lower end of the side pressure block 14 is slidably connected to the second slide rail 13. The upper end of the side pressure block 14 extends toward one end of the processing platform 3, and a second hydraulic cylinder 15 is arranged on the bottom plate 1 away from one end of the processing platform 3, and the telescopic end of the second hydraulic cylinder 15 is connected to the side pressure block 14.

[0021] The side clamping mechanism uses the second slide rail 13 and the second hydraulic cylinder 15 to drive the side pressure block 14 to move, thereby clamping the mold frame plate on the processing platform 3 to the left and right. Since the second slide rail 13 is arranged on the bottom plate 1 and its position is lower than the processing platform 3, the side pressure block 14 used is an L-shaped structure, so that its lower end can be connected to the second slide rail 13, and its upper end can extend into the processing platform 3. Of course, the part of the upper end of the side pressure block 14 extending to the processing platform 3 can fit with the processing platform 3, so that it can be more stable during the movement, keep the balance of the side pressure block 14, and clamp the mold frame plate with higher accuracy.

[0022] The first slide rail 5 is a dovetail structure.

[0023] The second slide rail 13 is a dovetail structure.

[0024] The first slide rail 5 and the second slide rail 13 both adopt a dovetail structure, so that the first slide rail 5 and the moving seat 6, the second slide rail 13 and the side pressure block 14 can withstand a large force other than the slide rail direction. That is, when the moving seat 6 and the movable top block 7 and the side pressure block 14 are subjected to the reaction force of the mold frame plate, they can only move along the slide rail direction on the corresponding first slide rail 5 or second slide rail 13, and will not be displaced in other directions. Therefore, the first slide rail 5 and the second slide rail 13 with a dovetail structure can make the moving seat 6 and the side pressure block 14 more capable of staying on the first slide rail 5 and the second slide rail 13, and can bear a greater force and have better stability.
