Description

Technical Field

[0001] This utility model relates to the field of mold clamping machines, and in particular to a large mold clamping machine with a rotating worktable. Background Technology

[0002] Mold clamping machines are mainly used to inspect the parallelism of molds. After placing the entire mold set on the lower worktable, the machine tool can automatically complete actions such as removing the lower mold, rotating the upper mold 180 degrees, and testing the mold pressure. This assists mold repair personnel in judging the parting surface fit effect, while reducing the labor intensity of mold repair personnel and improving work efficiency. With the continuous optimization of the market and customers' increasing demands for quality, traditional spray painting machines have been gradually phased out by the market due to the need for manual assembly in the later stages. Later, mold clamping machines that can handle two-color and three-color injection molds appeared on the market to meet market demands. However, mold clamping machines for two-color injection molds can only handle two-color molds, and mold clamping machines for three-color injection molds can only handle three-color molds. They cannot handle single-color, two-color, and three-color molds on a single machine. Furthermore, traditional mold clamping machines can only place one mold on the worktable for one mold clamping operation. When multiple injection molding operations are required for a workpiece, different mold clamping machines are needed for injection molding and mold clamping, resulting in high machine purchase costs, low work efficiency, and high production costs for manufacturing enterprises. Therefore, traditional single-function mold clamping machines are increasingly unable to meet the needs of current market development. The market needs larger, more functional multi-color mold clamping machines to meet production needs. Summary of the Invention

[0030] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Reference Figures 1 to 2As shown, this utility model discloses a large mold-closing machine with a rotating worktable, comprising a base 1, a left frame 2, a right frame 3, a slide 4, an upper platform 5, a lower platform 6, a moving platform 7, and a rotating worktable 8. The left frame 2 and the right frame 3 are respectively located on the two ends of the base 1. The upper ends of the left frame 2 and the right frame 3 are connected to a top cover 9. One end of the upper platform 5 is hinged to one end of the slide 4 via a hinge 10. The lower platform 6 is located on the base 1, and the moving platform 7 is located on the lower platform 6. The center bottom surface of the rotating worktable 8 is provided with a rotating shaft 11, and the rotating worktable 8 is rotatably mounted on the moving platform 7 via the rotating shaft 11.

[0033] A servo motor 12 is installed at one end of the moving stage 7, and a gear 13 is installed at the bottom of the rotary worktable 8. The output shaft of the servo motor 12 is connected to the gear 13 through a gear 14. The servo motor 12 drives the gear 13 to rotate, thereby driving the rotary worktable 8 to rotate. This design allows the servo motor 12 to drive the rotary worktable 8 to switch to a different workstation every certain angle of rotation. For example, if the rotary worktable 8 is set to rotate 60 degrees as one workstation, the rotary worktable 8 can have six workstations. The rotational accuracy of the rotary worktable 8 can reach one-thousandth of a degree, which has the advantages of high rotational accuracy and precise positioning. Multiple molds are evenly placed on the circumference of the rotary worktable 8. Each mold is used for corresponding injection molding and mold closing to achieve multiple injection molding of a workpiece, which has the advantages of high work efficiency and good injection molding effect.

[0034] In this embodiment, the above-described structural design enables the positioning accuracy of the rotary table 8 to be less than 0.05. The maximum rotational capacity of the mold clamping machine reaches 40 tons, and the maximum static pressure bearing capacity reaches 600 tons. It can meet the mold clamping requirements of single-color molds, two-color molds, and three-color molds on one machine, thus achieving multi-purpose functionality. This reduces the purchase and production costs for enterprises and solves the problem that existing mold clamping machines cannot meet the mold clamping requirements of single-color, two-color, and three-color molds on one machine due to their single function.

[0035] Reference Figure 2 , Figure 3 and Figure 6 As shown, a transmission sprocket 15 is installed at the bottom of the lower platform 6 away from the base 1. A transmission sprocket 16 and a driven sprocket 17 are provided on the side of the base 1 facing the lower platform 6. The transmission sprocket 16 and the driven sprocket 17 are coaxially arranged. The transmission sprocket 15 is connected to the transmission sprocket 16 via a chain 1. A hydraulic motor 18 is provided on the side of the base 1 facing the lower platform 6. A drive sprocket 19 is provided on the output shaft of the hydraulic motor 18. The drive sprocket 19 is connected to the driven sprocket 17 via a chain 2. A chain hanger 20 for fixing the chain is provided at the bottom of the movable table 7 away from the base 1. Several chain tensioning wheels 61 are provided at the bottom of the lower platform 6 along the moving direction of the movable table 7.

[0036] In this embodiment, the hydraulic motor 18 drives the moving table 7 to move back and forth linearly on the lower platform 6 via chain 2 and chain 1, thereby driving the rotating worktable 8 and the mold on it to move into the slide table 4 for mold closing, which ensures the advantages of high mold closing efficiency and good mold closing effect.

[0037] Reference Figure 1 As shown, the slide table 4 is equipped with a tilting cylinder, which is rotatably mounted on the slide table 4. The output shaft of the tilting cylinder is rotatably connected to the upper platform 5. At least two tilting cylinders are provided. The tilting cylinder drives the upper platform 5 to swing around the hinge 10 to achieve automatic tilting of the upper platform 5.

[0038] Reference Figure 1 As shown, the slide table 4 slides up and down on the left frame 2 and the right frame 3 via the lifting guide rail 22. The top cover 9 is longitudinally equipped with a mold closing cylinder 23. The output shaft of the mold closing cylinder 23 is connected to the top of the slide table 4. There are at least two mold closing cylinders 23. The at least two mold closing cylinders 23 drive the slide table 4 to move up and down together. The top cover 9 is also equipped with an oil tank 24 for supplying oil to the mold closing cylinder 23.

[0039] In this embodiment, four mold-closing cylinders 23 are preferably provided. In other embodiments, different numbers of mold-closing cylinders 23 can be provided according to actual conditions, so it is not limited to this. The four mold-closing cylinders 23 jointly drive the slide 4 and the upper platform 5 to move up and down, which makes the up and down movement of the slide 4 and the upper platform 5 more stable, thereby making the mold closing of the upper platform 5 and the rotary worktable 8 smoother and more stable.

[0040] Reference Figure 1 As shown, a rotary rocker arm 25 is rotatably mounted on the left frame 2 or the right frame 3. A safety rod 26 is provided at the swing end of the rotary rocker arm 25, and a compression spring 27 is sleeved on the upper end of the safety rod 26. A limiting ring 28 is also provided at the upper end of the safety rod 26 to limit the upper end of the compression spring 27.

[0041] In this embodiment, when the upper platform 5 or the rotary worktable 8 (i.e. the lower worktable) needs to be inspected, the rotary rocker arm 25 is swung to the bottom of the slide table 4 to prevent the slide table 4 from malfunctioning and sliding down freely. The slide table 4 or the upper platform 5 can be pressed against the top of the safety bar 26. The compression spring 27 plays a buffering role in the descent of the slide table 4 or the upper platform 5, which ensures the safety of the inspection and can avoid the occurrence of accidents.

[0042] Reference Figure 1 , Figure 4 and Figure 5 As shown, the left frame 2 and the right frame 3 are respectively provided with limit wheels 29 on their two inner sides. The limit wheels 29 are mounted on the base 1, and the two sides of the moving platform 7 are respectively provided with limit pads 30.

[0043] In this embodiment, the limiting wheel 29 presses against the corresponding limiting pad 30 to center and limit the moving stage 7, which ensures that the rotating worktable 8 and the moving stage 7 are in the predetermined position when the mold is closed, thereby improving the accuracy of mold closing.

[0044] Reference Figure 1 , Figure 4 and Figure 6 As shown, the top of one side of the base 1 is provided with several concave limiting blocks 31, and the side of the moving platform 7 is provided with several convex limiting blocks 32 corresponding to the concave limiting blocks 31.

[0045] In this embodiment, a number of concave limiting blocks 31 and a number of convex limiting blocks 32 cooperate to limit the movement stage 7, which ensures that the movement stage 7 can be accurately positioned at the predetermined position when it moves to the bottom of the slide table 4, thereby improving the accuracy of mold closing.

[0046] Reference Figure 1 , Figure 4 and Figure 5 As shown, the left frame 2 and the right frame 3 are respectively provided with several positioning pins 33 on their two inner sides. The positioning pins 33 are mounted on the base 1 through pin seats 34. The positioning pins 33 are connected to positioning cylinders 35. Several positioning cylinders 35 are respectively mounted on the left frame 2 and the right frame 3. Several limiting holes 36 are respectively installed on both sides of the moving table 7.

[0047] In this embodiment, the positioning cylinder 35 on the same side of the left frame 2 or the right frame 3 pushes the positioning pin 33 into the corresponding limiting hole 36 of the moving table 7 to lock the moving table 7, which prevents the moving table 7 from shifting during mold closing, thereby improving the accuracy of mold closing.

[0048] Reference Figure 1 As shown, the base 1 is provided with a base frame 37, and the base frame 37 is provided with several bottom support pads 38 of different thicknesses. The base 1 supports the moving platform 7 through the base frame 37 and the bottom support pads 38.

[0049] In this embodiment, the base 1 supports the movable stage 7 with bottom support pads 38 of different thicknesses to adapt to the different shapes of the bottom of the movable stage 7, so that the movable stage 7 can be placed stably on the base 1, which improves the stability of mold closing.

[0050] Reference Figure 4 and Figure 5 As shown, the rotary worktable 8 is provided with a guide groove 81, and a mold clamp 82 is installed on the guide groove 81. The mold clamp 82 positions the mold in the center on the rotary worktable 8. This design achieves the fixed and limited positioning of the mold, giving it the advantage of precise positioning.

[0051] Specifically, there is one or more guide grooves 81 and one or more clamping devices 82.

[0052] In this embodiment, multiple guide grooves 81 and multiple mold clamps 82 are provided. In other embodiments, different numbers of guide grooves 81 and mold clamps 82 can be provided according to actual conditions, so it is not limited thereto.

[0053] Reference Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the lower platform 6 is provided with translation guide rails 39 at both ends, and the base 1 is provided with a plurality of positioning components 40 located on the translation guide rails 39. The positioning components 40 include a lifting block 41, a lifting cylinder 42, a cylinder mounting plate 43, and rollers 44. The lifting block 41 is installed on the output end of the lifting cylinder 42, and the lifting cylinder 42 is fixedly installed to the translation guide rails 39 through the cylinder mounting plate 43. There is one or more rollers 44, which are respectively installed under the bottom surface of both ends of the moving platform 7. The moving platform 7 moves back and forth on the lower platform 6 through the rollers 44 and the translation guide rails 39. The bottom of both ends of the moving platform 7 facing the left frame 2 or the right frame 3 is provided with a plurality of limit wheels 45. The limit wheels 45 on the same side roll on the outer surface of the opposite translation guide rails 39.

[0054] In this embodiment, several positioning components 40 lower their corresponding rollers 44 to lower the entire moving platform 7 to the base 1. The lifting cylinder 42 lowers the lifting block 41 to lower the moving platform 7. Before the moving platform 7 moves horizontally, the lifting cylinder 42 raises the lifting block 41 to raise the moving platform 7. In the stationary state, the moving platform 7 rests on the base 1, reducing the load on the lifting cylinder 42 and extending its service life. Furthermore, the translation guide rail 39 and the limiting wheel 45 prevent the moving platform 7 from derailing, ensuring smooth linear movement on the lower platform 6.

[0055] Reference Figures 1 to 4As shown, the working process of this large mold clamping machine with a rotary worktable is as follows: the mold is centrally positioned on the rotary worktable 8 by the mold clamp 82. The rotary worktable 8, driven by the moving table 7 and the hydraulic motor 18, can move the mold directly under the slide table 4 or remove the mold after it has been clamped. The tilting cylinder drives the upper platform 5 to swing around the hinge 10 to automatically tilt the upper platform 5. By modifying the structure of the rotary worktable 8, the rotary worktable 8 is equipped with a station that can place multiple molds at the same time. The servo motor 12 drives the gear plate 13 to rotate to drive the rotary worktable 8. The rotating worktable 8 can switch to a different station every time it rotates a certain angle. When the slide table 4 and the upper platform 5 move downward under the drive of the mold closing cylinder 23, they can close the mold with the mold on the rotating worktable 8. In fact, it can perform single-color, two-color or three-color mold closing operations on the molds of each station on the rotating worktable 8 separately or simultaneously according to production needs. This solves the problem that the existing mold closing machine cannot meet the mold closing of single-color, two-color and three-color molds on one machine and the problem that the traditional mold closing machine can only close one mold at a time, resulting in low work efficiency.

[0056] The above embodiments are merely examples of this utility model and are not intended to limit the implementation and scope of this utility model. All technical solutions that are the same as or equivalent to the contents described in the claims of this utility model should be included within the protection scope of this utility model.
