[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 4 , the utility model provides a technical solution:

[0020] A clamping device for processing mold parts includes a base 1, a support base 2 symmetrically installed above the base 1, an electric push rod 3 installed on one side of the support base 2, and a clamping block 4 installed on the output shaft end of the electric push rod 3. A cavity 6 is provided inside the clamping block 4, a ladder block 5 is installed in the middle of the cavity 6, and clamping rods 7 in contact with the ladder block 5 are installed on both sides. Through holes are opened at both ends of the cavity 6, and a clamping block 8 is provided at one end of the clamping rod 7 that passes through the through hole, and a spring 10 is sleeved in the cavity, a movable rod 9 is installed at one end of the ladder block 5, and a moving mechanism for driving the movable rod 9 to move is installed inside the cavity.

[0021] During use, when clamping general mold parts, first place the mold on the base 1, then start the electric push rod 3 to drive the clamping blocks 4 on both sides to move toward the mold parts to achieve clamping. When clamping thin-walled tubular mold parts, first drive the clamping blocks 4 to move to the inside of the mold parts through the electric push rod 3, and then start the moving mechanism to drive the movable rod 9 to move. The movable rod 9 drives the trapezoidal block 5 to move and squeezes the clamping rods 7 on both sides so that the clamping rods 7 move toward the outside of the cavity 6 until the clamping block 4 at one end just contacts the inner wall of the mold part to achieve the effect of clamping and fixing, thereby avoiding the problem of easy damage to the mold parts by clamping from the outside, and can be adjusted according to the size of the inner diameter of the mold parts to clamp and fix the thin-walled tubular mold parts.

[0022] A rubber wear-resistant pad is installed on one side of the clamping block 4 to improve the firmness of the clamping.

[0023] A limit plate is symmetrically installed inside the cavity 6, and the tightening rod 7 passes through the limit plate. One end of the spring 10 contacts the inner wall of the cavity 6, and the other end is connected to the limit plate.

[0024] One end of the pressing rod 7 close to the ladder block 5 is provided with an inclined surface matching therewith.

[0025] The moving mechanism includes a fixed frame 11 installed inside the cavity 6, a gear 13 installed on one side of the fixed frame 11, and a rack 12 installed on the outside of the movable rod 9. The gear 13 and the rack 12 are meshed with each other. A servo motor is installed on one side of the fixed frame 11 to drive the gear 13 to rotate.

[0026] Start the servo motor to drive the gear 13 to rotate, and with the cooperation of the rack 12, drive the movable rod 9 to move, thereby driving the ladder block 5 to move, and squeeze the clamping rods 7 on both sides, so as to adjust the moving position of the clamping rods 7 to achieve the purpose of clamping and fixing. After the processing is completed, drive the gear 13 to rotate in the opposite direction, so that the ladder block 5 moves away from the clamping rod 7. At this time, the elastic force is restored by the spring 10, and then the clamping rod 7 is driven to move into the cavity 6, thereby releasing the clamping.

[0027] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
