DETAILED DESCRIPTION

[0021] The following further describes the present application in detail with reference to the drawings. It is necessary to point out that the following detailed description is only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] As Figures 1-6 shown, the injection molding machine mold automatic clamping tool comprises a bottom plate 1 and support blocks 11 installed at the bottom of the four corners of the bottom plate 1, the top of the bottom plate 1 is rotationally connected with a rotating table 2, the outside of the rotating table 2 is installed with an annular plate 21, a plurality of sets of clamping mechanisms 3 are installed on the annular plate 21, the clamping mechanism 3 comprises a mounting frame 31 in U-shaped structure installed at the top of the annular plate 21, two clamping plates 32 sleeved outside the mounting frame 31, and a strip-shaped opening 33 opened at the top of the annular plate 21 and below the mounting frame 31, the bottom of the mounting frame 31 is installed with an elastic mechanism for driving the two clamping plates 32 to move close to each other, the elastic mechanism comprises a limiting rod 5 installed at the bottom of the mounting frame 31 and two springs 51 sleeved outside the limiting rod 5, the two clamping plates 32 are sleeved outside the limiting rod 5, the bottom of the two clamping plates 32 is installed with a moving plate 52 in inverted triangular structure, and the moving plate 52 passes through the strip-shaped opening 33 and extends below the annular plate 21, the two ends of the two springs 51 are fixedly connected with one side of the two clamping plates 32 and the side wall of the mounting frame 31 respectively;

[0023] The top of the bottom plate 1 is provided with a driving mechanism and a limiting mechanism matched with the clamping mechanism 3. The driving mechanism and the limiting mechanism are oppositely arranged. The driving mechanism is located at the material feeding end of the rotating table 2, and the limiting mechanism is located at the processing end of the rotating table 2. In this way, when the work of taking and placing is carried out, the processing equipment will not be approached, and the safety of the device is improved. The driving mechanism comprises a first pneumatic cylinder 6 mounted on the top of the bottom plate 1, and a driving plate 61 mounted on the output end of the first pneumatic cylinder 6 and matched with the adjacent two moving plates 52 and in a trapezoidal structure. The driving plate 61 is in an isosceles trapezoidal structure. The top of the driving plate 61 is provided with a mounting groove on both sides. The first roller 62 is rotatably connected in the mounting groove. The limiting mechanism comprises a second pneumatic cylinder 7 mounted on the top of the bottom plate 1, and a fixed plate 71 mounted on the output end of the second pneumatic cylinder 7. The top of the fixed plate 71 is provided with two limiting plates 72 matched with the moving plates 52. The two limiting plates 72 are provided with an inclined angle 73 matched with the moving plates 52 on the side close to each other. The top of the inclined angle 73 is provided with a fixed groove 74. The second roller 75 is mounted in the fixed groove 74. When the driving plate 61 contacts with the moving plate 52, the first roller 62 will slide along the inclined surface of the moving plate 52. When the inclined angle 73 of the limiting plate 72 contacts with the moving plate 52, the second roller 75 will slide along the inclined surface of the other side of the moving plate 52, thereby reducing the friction between the driving plate 61 and the limiting plate 72 and the moving plate 52.

[0024] The top of the bottom plate 1 is provided with a rotating motor 4. The output end of the rotating motor 4 is provided with a driving wheel 41. The outside of the rotating table 2 is provided with a driven wheel 42 engaged with the driving wheel 41. When the mold is processed, the rotating motor 4 will drive the driving wheel 41 to rotate. Under the cooperation of the driving wheel 41 and the driven wheel 42, the rotating table 2 will drive the annular plate 21 to rotate. Since the rotating motor 4 is a stepping motor, when the rotating table 2 rotates by ninety degrees, the rotating motor 4 will stop rotating. When the driving mechanism and the limiting mechanism complete the work, the rotating motor 4 will rotate again. The number of clamping mechanisms 3 is four, and they are evenly distributed on the annular plate 21. In this way, the mold can be continuously processed, and the efficiency of the mold processing is improved.

[0025] It needs to be explained that when one clamping mechanism rotates to the side of the driving mechanism, the first pneumatic cylinder 6 drives the driving plate 61 to move up, when the driving plate 61 contacts the two adjacent moving plates 52, the driving plate 61 pushes the two moving plates 52 to move away from each other, at this time the two springs 51 will be elastically deformed, the staff can take the mold after processing from the top of the mounting frame 31, then place the mold to be processed on the top of the mounting frame 31 between the two clamping plates 32, then the first pneumatic cylinder 6 drives the driving plate 61 to move down, when the driving plate 61 is separated from the two moving plates 52, the two clamping plates 32 are driven to move to each other under the action of the elasticity of the two springs 51, so as to fix the mold between the two clamping plates 32, when one clamping mechanism rotates to the side of the limiting mechanism, the second pneumatic cylinder 7 drives the fixed plate 71 to move up, at this time the two limiting plates 72 arranged on the fixed plate 71 move up, the two limiting plates 72 move to the sides of the two adjacent moving plates 52, and the inclined angle 73 of the limiting plate 72 is attached to one side of the moving plate 52, so that when the mold is processed, the two moving plates 52 can be limited to prevent the spring 51 from deforming, causing the clamping force to be not tight, affecting the quality of processing.

[0026] Embodiment 2

[0027] As Figure 7 shown, the difference between this embodiment and embodiment 1 is that the top of the fixed plate 71 is provided with a T-shaped sliding groove 8, the inside of the T-shaped sliding groove 8 is slidably connected with two T-shaped sliding blocks 81, the top of the two T-shaped sliding blocks 81 is respectively fixedly connected with the bottom of the two limiting plates 72, a plurality of mounting holes 82 communicating with the T-shaped sliding groove 8 are arranged on one side of the fixed plate 71, a fixing hole is arranged on one side of each of the two T-shaped sliding blocks 81 and matched with the mounting hole 82, the fixing hole and one of the mounting holes 82 are fixed by a bolt, when it is needed to adjust the position of the limiting plate 72, the bolt can be unscrewed from the fixing hole and the one of the mounting holes 82, after adjusting the position of the limiting plate 72, the bolt is screwed into the fixing hole and the other mounting hole 82, so that the T-shaped sliding block 81 can be fixed, and then the limiting plate 72 can be fixed;

[0028] The further improved feature of this embodiment is that the position of the two limiting plates 72 can be adjusted according to the width of the mold during use, when the limiting mechanism is working, the inclined angle 73 of the limiting plate 72 can be attached to the inclined surface of the moving plate 52, so as to limit the moving plate 52, so that molds of different widths can be processed, improving the universality of the device.

[0029] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
