Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, specifically to a clamping platform for a large mold tilting device. Background Technology

[0002] Currently, most large mold slant tools are irregularly shaped and weigh around 200 kg. The slider angle of the slant tool is generally 30, 45, 50, or 60 degrees. The back of the slant tool is usually equipped with inserts. When machining the inserts installed on the slant tool, it is difficult to drill, clamp, and align the mold slant tool. The main method is to use the small flat surface at the tail of the slant tool to clamp it on a drilling machine and use the T-slot of the drilling machine as a fulcrum to assist in alignment. The vertical accuracy of the hole is within 0.1 mm. Clamping and alignment is time-consuming, labor-intensive, inefficient, and difficult to guarantee machining accuracy, resulting in high costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a clamping platform for large mold slant tools, which solves the problems of difficult drilling, clamping and alignment of large mold slant tools, time-consuming and labor-intensive clamping and alignment, poor positioning and clamping accuracy, low efficiency and high cost.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a clamping platform for a large mold tilting device, comprising a main support plate, a rocker arm, a lead screw jack, a clamping platform, a secondary support plate, a base plate, and lifting lugs, wherein four lifting lugs are provided at relative positions on the base plate, the bottom of the lead screw jack is fixedly connected to the base plate by bolts, the bottoms of the main support plate and the secondary support plate are symmetrically fixedly connected to relative positions on the base plate by bolts, the upper parts of the main support plate and the secondary support plate are each fixedly connected to a corresponding pivot support and locking block by a pivot shaft, and the pivot support is fixedly connected to the bottom surface of the clamping platform by bolts at corresponding positions; The clamping platform is provided with a vertical groove and a horizontal groove. A vertical key is provided in the vertical groove and a horizontal key is provided in the horizontal groove. When the clamping platform is in the flipped state, the horizontal groove is located at the corresponding low horizontal position of the clamping platform. The clamping platform is also covered with uniformly arranged clamping bolt holes, and an angle display is provided at the corresponding position of the clamping platform. At the corresponding position on the bottom surface of the clamping platform, a jack hinge seat is fixedly connected by bolts. The jack hinge seat is hinged to the top of the lead screw jack through a double-headed hinge plate. The lead screw of the lead screw jack is linearly connected to a rocker arm through a coupling, wherein the rod of the rocker arm passes through the rocker arm groove in the main support plate.

[0005] A further improvement is that the gap between the vertical key and the vertical groove, and the gap between the horizontal key and the horizontal groove on the clamping platform are both less than 0.03 mm.

[0006] A further improvement is that when the clamping surface of the clamping table is in a horizontal position, the rotating shaft support on the clamping table is connected to the corresponding main support plate and the secondary support plate by an inserted pin.

[0007] A further improvement is that when the clamping surface of the clamping table is in the flipped position, the lowest end of the clamping table is connected to the base plate by a pad block.

[0008] A further improvement is that there are multiple pads, which are rectangular blocks and each has a different height. Their bottoms contact the pad grooves provided on the base plate, and their tops contact the lowest end of the clamping table.

[0009] Further improvements are made of 45# steel for the main support plate, rocker arm, rotating shaft, rotating shaft support, locking block, double-headed hinge plate, clamping platform, vertical key, horizontal key, jack hinge seat, auxiliary support plate, base plate, lifting lug, and pad.

[0010] A further improvement is that the surface hardness of the clamping table, vertical key, and horizontal key is HRC55.

[0011] A further improvement is that the minimum division value of the angle display is 0.01º.

[0012] A further improvement is that the angle formed between the clamping surface of the clamping table and the horizontal plane is the flip angle of the clamping table, and the limit value of the flip angle of the clamping table is 0º~75º.

[0013] A further improvement is that the clamping platform of the large mold inclined plate has a maximum load of 300 kg, and can clamp one or more large mold inclined plates for processing at a time.

[0014] The beneficial effects of this invention are as follows: This invention provides a clamping platform for large mold slant tools, which enables rapid and accurate drilling, clamping, and alignment of large mold slant tools, significantly improving efficiency, with a positioning and clamping accuracy of less than 0.05 mm, and reducing manufacturing costs.

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] See Figures 1 to 4 As shown, this embodiment of the invention provides a clamping platform for a large mold tilting device, including a main support plate 2, a rocker arm 3, a lead screw jack 8, a clamping table 10, a secondary support plate 18, a base plate 19, and lifting lugs 20. Four lifting lugs 20 are provided on the base plate 19 at opposite positions. The bottom of the lead screw jack 8 is fixedly connected to the base plate 19 by bolts. The bottoms of the main support plate 2 and the secondary support plate 18 are symmetrically fixedly connected to the base plate 19 at opposite positions by bolts. The upper parts of the main support plate 2 and the secondary support plate 18 are each fixedly connected to a corresponding pivot support 6 and a locking block 7 via a pivot 4. The pivot support 6 is fixedly connected to the bottom surface of the clamping table 10 at a corresponding position by bolts. The clamping table 10 is provided with a vertical groove 11 and a horizontal groove 16. A vertical key 12 is provided in the vertical groove 11 and a horizontal key 14 is provided in the horizontal groove 16. When the clamping table 10 is in the flipped state, the horizontal groove 16 is located at the corresponding low horizontal position of the clamping table 10. The clamping table 10 is also covered with uniformly arranged clamping bolt holes 15. An angle display 13 is also provided at the corresponding position of the clamping table 10. At the corresponding position on the bottom surface of the clamping platform 10, a jack hinge seat 17 is fixedly connected by bolts. The jack hinge seat 17 is hinged to the top of the lead screw jack 8 through a double-headed hinge plate 9. The lead screw of the lead screw jack 8 is linearly connected to a rocker arm 3 through a coupling, wherein the rod of the rocker arm 3 passes through the rocker arm groove 1 in the main support plate 2.

[0019] See Figure 2 As shown, on the clamping table 10, the gap between the vertical key 12 and the vertical groove 11, and the gap between the horizontal key 14 and the horizontal groove 16 are both less than 0.03 mm. This embodiment is to ensure that the positioning and clamping accuracy of the large mold tilting device is less than 0.05 mm.

[0020] See Figure 2As shown, when the clamping surface of the clamping table 10 is in a horizontal position, the rotating shaft support 6 on the clamping table 10 is connected to the corresponding main support plate 2 and secondary support plate 18 by an inserted pin 5. This embodiment is to limit the rotation of the clamping table 10, ensure that the clamping surface is in a horizontal position, and facilitate the positioning and clamping of the large mold tilting device.

[0021] See Figure 3 As shown, when the clamping surface of the clamping table 10 is in the flipped position, the lowest end of the clamping table 10 is connected to the base plate 19 by a pad block 21. See Figure 1 As shown, there are multiple pads 21, which are rectangular blocks and each has a different height. Their bottoms contact the pad grooves 22 provided on the base plate 19, and their tops contact the lowest end of the clamping table 10. In the above embodiments, the pad 21 is to provide a supporting force for the clamping table 10 to prevent the clamping table 10 from rotating due to overload when machining large mold inclined pieces, thus affecting the machining accuracy.

[0022] See Figure 1 As shown, the main support plate 2, rocker arm 3, rotating shaft 4, rotating shaft support 6, locking block 7, double-headed hinge plate 9, clamping table 10, vertical key 12, horizontal key 14, jack hinge seat 17, auxiliary support plate 18, base plate 19, lifting lug 20, and pad block 21 are all made of 45# steel. See Figures 1 to 3 As shown, the surface hardness of the clamping table 10, the vertical key 12, and the horizontal key 14 is HRC55. In the above embodiments, the 45# steel material is easy to heat treat and machine, and the surface hardness of HRC55 can enhance the wear resistance and service life of the material.

[0023] See Figure 3 As shown, the minimum division value of the angle display 13 is 0.01º. In this embodiment, it is used to quickly and accurately adjust the flip angle of the clamping table 10, which facilitates the alignment of the large mold tilting device and greatly improves the processing efficiency.

[0024] See Figures 2 to 3 As shown, the angle formed between the clamping surface of the clamping table 10 and the horizontal plane is the flipping angle of the clamping table 10, and the limit value of the flipping angle of the clamping table 10 is 0º~75º.

[0025] See Figure 3 As shown, the clamping platform of the large mold inclined plate has a maximum load of 300 kg and can clamp one or more large mold inclined plates for processing at a time.

[0026] In addition, the lead screw jack 8 and angle display 13 described in this invention are existing mature technologies. Their structure, function and use are not described in detail in this specification, and are technologies known in the field.

[0027] The working principle of this invention is as follows: First, use a lifting tool to connect the lifting lug 20 on the base plate 19, lift the clamping platform of the large mold inclined device to the corresponding position of the drilling machine processing platform and lock it. Then, turn the rocker arm 3 to make the screw jack 8 drive the clamping platform 10 to rotate until the clamping platform 10 rotates around the rotating shaft 4 to the horizontal position of the clamping surface and stops, and use the pin 5 to lock the rotation of the clamping platform 10. Then as Figure 4 As shown, the large mold tilting device is placed on the clamping surface of the clamping table 10. The mold tilting device is positioned by the vertical key 12 or the horizontal key 14. The large mold tilting device is positioned and clamped on the clamping table 10 by the threaded connection between the bolts on the pressure plate and the clamping bolt holes 15. Subsequently, remove the pin 5, turn the rocker arm 3, so that the screw jack 8 drives the clamping table 10 to rotate, and adjust the rotation angle of the clamping table 10 through the angle display 13 to align the machining surface of the large mold inclined piece to a horizontal position, so that its horizontal accuracy is less than 0.05 mm. Finally, place the pad 21 in the pad groove 22 of the base plate 19, so that the top of the pad 21 is close to the lowest end of the corresponding clamping table 10. Then, by lowering the screw jack 8, the clamping platform of the large mold inclined device is locked, and the drilling machine is started to process the machining surface of the large mold inclined device.
