Description

Technical Field

[0001] This utility model relates to the field of mold fixing technology, specifically to a fixing fixture for mold processing. Background Technology

[0002] A mold is a tool that uses external force to shape a blank into a part with a specific shape and size. It is widely used in blanking, die forging, cold heading, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. During mold production, the blank material needs to be fixed on the processing equipment by a fixture, and its interior is processed to make its internal shape meet the standard of the part.

[0003] For example, the utility model patent with publication number CN223114959U describes a fixing fixture for mold processing, including a base and a support plate. A fixing seat is fixedly connected to one side of the base, and a motor is fixedly connected to the top surface of the fixing seat. In this utility model, the motor drives the pulley to rotate, and the pulley drives the threaded rod to rotate through the pulley on the transmission belt. The threaded rod drives the fixing block to rotate on the threaded movable block. The arc groove on the fixing block is adapted to the arc mold, and the edge of the fixing block is adapted to the solid mold, which enhances the fixing effect of the mold. The motor drives the threaded rod to rotate, and the threaded rod drives the threaded movable block to move. The movable block quickly drives the support plate on the transmission rod and the transmission rod. The height of the support plate is adjusted to suit the usage habits of users of different heights and improve the efficiency of fixing the mold.

[0004] However, existing fixed tooling requires tool setting after fixing the mold to improve machining accuracy, which reduces the machining efficiency of the mold.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0020] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, the present invention provides a fixing fixture for mold processing, comprising: a worktable 1, a fixing mechanism 3 for positioning and fixing the mold; a limiting groove 2 is installed on the circumference of the worktable 1, and the fixing mechanism 3 is limited by the limiting groove 2 when fixing the mold, so that the fixing mechanism 3 can fix the mold in the center.

[0022] The fixing mechanism 3 includes: a cylinder 31, which is fixedly mounted on a fixing plate 32. The fixing plate 32 is fixedly mounted on the edge of the bottom of the workbench 1, and four fixing plates 32 are distributed circumferentially; the piston rod of the cylinder 31 slides through the fixing plate 32, and a moving block 33 is fixedly connected to the piston rod of the cylinder 31. The moving block 33 is slidably mounted in the limiting groove 2. A clamping plate 34 is fixedly mounted on the top of the moving block 33. The clamping plate 34 is slidably mounted on the top of the workbench 1. The piston rod of the cylinder 31 pushes the moving plate to move, and the moving plate drives the clamping plate to move. The plate 34 moves, allowing the clamping plate 34 to clamp the mold and fix it. The clamping plate 34 has multiple vertical through slots, in which mounting blocks 35 are slidably installed. One end of the mounting block 35 has an arc-shaped groove, in which a vertical fixing rod is fixedly installed. A roller 36 is rotatably installed on the fixing rod. The roller 36 contacts the mold. After the rollers 36 on both sides of the mold clamp the mold in the center, the mold can move in another direction, so that the clamping plate 34 in the other direction can fix the mold in the center, improving the positioning accuracy of the mold.

[0023] Furthermore, the length of the mounting block 35 is greater than the thickness of the clamping plate 34, allowing the roller 36 to contact the mold before the clamping plate 34. After the roller 36 contacts the mold, the clamping plate 34 slides on the mounting block 35, thereby clamping and fixing the mold. This prevents the fixing rod from wearing out due to vibration of the mold during processing and ensures the stability of the processing.

[0024] It should be noted that the spacing between adjacent rollers 36 is smaller than the width of the mold, resulting in a smaller spacing between the mounting blocks 35 installed on a mounting plate 37. During the process of the rollers 36 clamping the mold, the mold will not directly contact the surface of the clamping plate 34 between adjacent fixing blocks, thus affecting the clamping of the mold in another direction.

[0025] Mounting block 35 is fixedly mounted on mounting plate 37. Multiple limiting rods 38 slide and pass through mounting plate 37. One end of limiting rod 38 is fixedly connected to clamping plate 34, and the other end of the limiting rod is fixedly connected to limiting block. A spring 39 is sleeved on limiting rod 38. One end of spring 39 is fixedly connected to mounting plate 37, and the other end of spring 39 is fixedly connected to limiting block. When clamping plate 34 moves, clamping plate 34 drives limiting rod 38 to move, limiting rod 38 drives limiting rod 38 to move, limiting block drives spring 39 to move, spring 39 pushes mounting plate 37 to move, mounting plate 37 drives mounting block 35 to move, mounting block 35 drives fixing rod to move, fixing rod drives roller 36 to move, so that roller 36 contacts mold. After mold is clamped, mounting plate 37 continues to move, and spring 39 is stretched. Mounting plate 37 contacts mold, so that mold is firmly fixed.

[0026] It should be added that a traction rope and two fixed pulleys are used to replace one of the aligned cylinders 31. The two ends of the traction rope are respectively connected to the same side of the two aligned moving plates, and the traction rope passes through the two fixed pulleys, which are installed on the fixed plate 32. The fixed pulleys cause the direction of the traction rope to turn 90° twice. When the piston rod of the cylinder 31 pushes one moving plate to move, the moving plate pulls the other moving plate to move through the traction rope. Furthermore, by installing a spring 39 between the fixed plate 32 and the moving plate corresponding to the replaced cylinder 31, both moving plates can be reset.

[0027] Working principle: First, one set of cylinders 31 is activated. The piston rod of cylinder 31 pushes the moving plate to move, which in turn moves the clamping plate 34. The clamping plate 34 moves the mounting plate 37 via spring 39, which in turn moves the mounting block 35. The mounting block 35 then moves the roller 36 to contact the mold. After the roller 36 clamps the mold in the center, another set of cylinders 31 is activated, causing the other set of rollers 36 to clamp the mold in another direction. The moving plate stretches the spring 39, causing the clamping plate 34 to clamp and fix the mold. The first set of cylinders 31 continues to push the moving plate to move, so that the four clamping plates 34 clamp and fix the four sides of the mold respectively, ensuring the firmness of the fixation, thereby ensuring the processing accuracy, positioning the mold, reducing the number of mold tool settings, and improving the processing efficiency of the mold.
