Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an electric spark machine tool fixing clamp used for processing injection molds. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. Injection molding requires the use of injection molds, and injection molds often need to be processed by EDM machines.

[0003] The EDM machine tool, also known as CNC EDM machine tool, EDM, spark machine, etc., is a kind of electrical processing equipment. When the Soviet Lazarenko couple studied the phenomenon and cause of the damage of switch contacts by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can make the local metal melt, oxidize and corrode, thus creating and inventing the EDM method.

[0004] The traditional EDM machine tool has a single clamping function, which can only realize clamping based on the X and Y axis directions of the machine tool, but cannot realize the biased clamping of the connection. When opening the bevel groove on the mold, the XY axis moving mechanism of the spark machine mechanism needs to cooperate with each other to complete the processing. However, this method causes a large movement error of the machine head, which affects the processing accuracy.

[0005] Therefore, how to provide an EDM machine tool fixing fixture for injection mold processing to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0006] In view of this, the purpose of the present application is to provide an EDM machine tool fixing fixture for injection mold processing, so as to solve the problem that when opening a bevel groove on the mold, the XY axis moving mechanism of the spark machine mechanism needs to cooperate with each other to complete the processing. However, this method leads to a large movement error of the machine head, thereby affecting the processing accuracy.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A fixing fixture of an electric spark machine tool for processing injection molds comprises a base plate, one side of the top end of the base plate is rotatably connected to a rotating block via a rotating shaft, the rotating block is fixedly connected to a clamping table, the side of the clamping table away from the rotating block is fixedly connected to an arc plate via a fixing frame, the side of the arc plate is provided with worm gears, the other side of the top end of the base plate is fixedly connected to two support plates, a worm is rotatably connected between the two support plates, the worm is meshed with the worm gears, and one end of the worm is fixedly connected to an adjusting handwheel.

[0009] Preferably, a clamping plate and a fixed plate are respectively installed on both sides of the top of the clamping platform, and a sliding groove is opened at the top of the clamping platform, and the sliding groove is slidably connected with a movable plate.

[0010] Preferably, a threaded rod is threadedly connected to the middle portion of the fixed plate, and a terminal end of the threaded rod is rotatably connected to the movable plate.

[0011] Preferably, mounting holes are provided at the four corners of the base plate.

[0012] Preferably, the center of the arc-shaped plate corresponds to the rotation axis.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The clamping table in the utility model can be adjusted and rotated in the horizontal direction, so that the workpiece can be processed at an angle. When in use, the workpiece is placed on the top of the clamping table, and then the threaded rod is rotated. At this time, the workpiece is clamped by the fixed plate and the clamping plate. When the workpiece needs to be processed at an angle, the worm is driven to rotate by the hand-cranked wheel, and the worm drives the arc plate to rotate with the rotating shaft as the center through the worm teeth, thereby realizing the deflection of the entire clamping table, and then high-precision bevel processing of the workpiece can be achieved, so that the processing groove direction is consistent with the X or Y axis direction of the spark machine head, reducing the influence of the head movement error on the processing accuracy.
