[0001] This utility model relates to the field of machining oblique holes in mold plates, specifically to a device for forming oblique holes in mold plates. Background Technology

[0002] Currently, when processing some mold plates, it is necessary to drill holes in the mold plates. The requirements for drilling are that the holes be inclined inward and not through. Because the holes are relatively deep, after the holes are formed, waste chips will enter the holes during the drilling process and are difficult to remove, affecting the smoothness of the holes. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a device for forming oblique holes in a mold plate.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a mold plate inclined hole forming device, including a bracket, a base plate movably inserted at the middle end of the bracket, two symmetrically arranged clamping plates slidingly arranged on the lower surface of the base plate, fixing plates fixed at both ends of the base plate on the bracket, a drilling assembly provided on the lower surface of the fixing plates, a U-shaped fixing frame fixedly arranged on the upper surface of the two fixing plates, a U-shaped connecting frame movably inserted on the fixing frame, the bottom of both ends of the connecting frame fixed to the base plate, two vertically arranged upright plates fixed at the middle end of the upper surface of the fixing frame, L-shaped connecting rods movably inserted at both ends of the upright plates, the vertical end of the connecting rods fixed to the connecting frame, a horizontally arranged movable plate between the two upright plates, a rectangular groove penetrating through the middle end of the movable plate, an arc groove formed at the diagonal of the rectangular groove, a Y-shaped pushing block rotatably inserted at the middle end of the rectangular groove, a vertically arranged rotating shaft fixed at the middle end of the pushing block, and the bottom of the rotating shaft rotatably penetrating through the fixing frame.

[0005] Preferably, a long plate is fixedly provided on the upper surface of the base plate, and a lead screw with opposite threads at both ends is rotatably provided inside the long plate. Fixed rods are slidably provided at both ends of the long plate, and the fixed rods are L-shaped with the end away from the long plate fixedly connected to the clamping plate.

[0006] Preferably, the drilling assembly includes a vertical plate, which is vertically fixed to the lower surface of a fixed plate. An L-shaped support plate is fixedly installed on the vertical plate, and an inclined electric push rod is fixedly installed on the support plate. A placement plate is coaxially fixed to the output end of the electric push rod, and a drilling machine is fixedly installed on the side of the placement plate away from the electric push rod.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] In this invention, after the inner inclined hole is machined on the mold plate, it is subsequently driven by a second motor at the machining station. At the same time, since the inclined groove inside the mold plate is set upward as a whole, and under the continuous action of the mold plate moving repeatedly, the waste chips that fall into the groove during drilling are discharged, thus avoiding affecting the smoothness of the hole.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-5As shown, this utility model provides a device for forming oblique holes in a mold plate, including a support 1. A base plate 11 is movably inserted into the middle end of the support 1. Two symmetrically arranged clamping plates 16 are slidably arranged on the lower surface of the base plate 11. Fixing plates 2 are fixedly installed on the support 1 at both ends of the base plate 11. Drilling assemblies are provided on the lower surface of the fixing plates 2. A fixing frame 3 with an inverted U-shape is fixedly installed on the upper surface of the two fixing plates 2. A connecting frame 31 with an inverted U-shape is movably inserted into the fixing frame 3. The bottom ends of the connecting frame 31 are fixed to the base plate 11. The upper surface of the fixing frame 3... Two vertically arranged upright plates 32 are fixedly provided at the middle end. L-shaped connecting rods 33 are movably inserted at both ends of the upright plates 32. The vertical end of the connecting rods 33 is fixed on the connecting frame 31. A horizontally arranged movable plate 34 is provided between the two upright plates 32. A rectangular groove 35 is opened through the middle end of the movable plate 34. An arc groove 36 is opened at the diagonal of the rectangular groove 35. A Y-shaped pushing block 37 is rotatably inserted into the middle end of the rectangular groove 35. A vertically arranged rotating shaft 38 is fixed at the middle end of the pushing block 37. The bottom of the rotating shaft 38 rotatably passes through the fixed frame 3.

[0018] A long plate 12 is fixedly mounted on the upper surface of the base plate 11. A lead screw 13 with opposite threads at both ends is rotatably mounted inside the long plate 12. Fixed rods 15 are slidably mounted at both ends of the long plate 12. The fixed rods 15 are L-shaped and the end away from the long plate 12 is fixedly connected to the clamping plate 16. When the lead screw 13 is driven to rotate, the fixed rods 15 threaded at both ends of the rotating lead screw 13 will push the clamping plate 16 to clamp the side wall of the mold plate placed on the base plate 11, avoiding the problem of shaking and deviation during drilling. A first motor 14 is fixedly mounted on one end of the long plate 12. The output end of the first motor 14 is coaxially fixed at one end of the lead screw 13. The first motor 14 can provide power for the rotation of the lead screw 13, which is convenient for the operator to operate.

[0019] The bottom of the clamping plate 16 is fixed with a support plate 17 that is perpendicular to itself. The clamping plate 16 and the support plate 17 are arranged in an L-shape. This arrangement allows the clamping plate 16 to clamp the mold plate placed on the base plate 11, and the support plate 17 to support the mold plate, thereby completely and stably clamping and fixing the mold plate, ensuring the stability of the mold plate during drilling and preventing deviation.

[0020] The drilling assembly includes a vertical plate 21, which is vertically fixed to the lower surface of the fixed plate 2. An L-shaped support plate 22 is fixedly installed on the vertical plate 21. An inclined electric push rod 23 is fixedly installed on the support plate 22. A placement plate is coaxially fixed to the output end of the electric push rod 23. A drilling machine 24 is fixed to the side of the placement plate away from the electric push rod 23. A second motor 39 is fixed to the lower surface of the middle end of the fixed frame 3. The output end of the second motor 39 is coaxially fixed to the rotating shaft 38. The second motor 39 can provide power for the movement of the base plate 11, thereby facilitating operation by the staff.

[0021] The top of the fixed frame 3 has grooves 41 extending through both ends of the connecting frame 31. Two symmetrically arranged limiting rods 4 are fixed in the grooves 41. One end of the connecting frame 31 located in the groove 41 is movably inserted into the limiting rods 4. By setting the limiting rods 4, the connecting frame 31 can be stably moved back and forth repeatedly within the fixed frame 3 when it moves, avoiding deviations that affect the movement.

[0022] Working principle: During use, the operator can place the mold plate to be processed into the groove inside the base plate 11, such as... Figure 2 Within the groove shown, the first motor 14 drives the lead screw 13 to rotate. At this time, the fixed rods 15 threaded into both ends of the rotating lead screw 13 push the clamping plate 16 to clamp the side wall of the mold plate placed on the base plate 11, preventing wobbling and deviation during drilling. Subsequently, the inclined electric push rod 23 fixed on the support plate 22 pushes the drilling machine 24 to move. At this time, the output end of the drilling machine 24 operates, and the drilling machine 24 gradually tilts and enters the mold plate to drill, forming a hole as shown. Figure 1As shown, by tilting the drilling machine 24 upwards as described above, the inclined holes in the mold plate will be tilted upwards as a whole. At this time, the electric push rod 23 will drive the drilling machine 24 away from the clamped mold plate, and the second motor 39 can start working. The second motor 39 can drive the rotating shaft 38 to rotate. At this time, the rotating shaft 38 will drive the top fixed push block 37 to rotate. One end of the rotating push block 37 will abut against the side wall of the rectangular groove 35. At this time, the movable plate 34 will move towards one end of the push block 37. At this time, the connecting rod 33 fixed at the end of the movable plate 34 will connect with the connecting rod 35. The frame 31 and the base plate 11 move together. As the push block 37 rotates into the arc groove 36, the other end of the push block 37 will abut against the other side of the rectangular groove 35. At this time, the movable plate 34 drives the entire connecting frame 31 and the base plate 11 to return to their original position. After the second motor 39 works, the connecting frame 31 can be driven to move the base plate 11 repeatedly left and right. At this time, since the inclined groove in the mold plate is set upward, and under the continuous action of the repeatedly moving mold plate, the waste chips that fall into the groove during drilling are discharged, avoiding affecting the smoothness of the hole.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
