[0017] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown, a mobile frame of a shooting platform 3 for an injection molding machine includes a base 1, a sliding frame 2, a shooting platform 3, a lifting mechanism 4, an adjusting mechanism 5 and a proofreading mechanism 6.

[0019] like Figure 1 , Figure 2 As shown, the base 1 is horizontally arranged on the injection molding machine, the sliding frame 2 is arranged above the base 1, and the shooting platform 3 is horizontally slidably connected to the sliding frame 2 and is used to horizontally pass through the center hole on the fixed template 7.

[0020] like Figure 1 , Figure 2 As shown, the lifting mechanism 4 is disposed between the base 1 and the sliding frame 2 and is used to adjust the height direction of the sliding frame 2 . The lifting mechanism 4 includes a bottom plate 41 , a top plate 42 , a connecting block 43 , a bidirectional screw 44 and a lifting rod 45 .

[0021] like Figure 1 , Figure 2 As shown, the bottom plate 41 is arranged on the base 1, and the top plate 42 is arranged above the bottom plate 41. A pair of connecting blocks 43 are arranged between the two ends of the bottom plate 41 and the top plate 42, and the bidirectional screw rods 44 are rotatably connected to the pair of connecting blocks 43. The lifting rods 45 are arranged in pairs and rotatably arranged at the upper and lower ends of the connecting blocks 43, and the ends of the lifting rods 45 away from the connecting blocks 43 are rotatably connected to the bottom plate 41 and the top plate 42.

[0022] like Figure 1 , Figure 2 As shown, the adjustment mechanism 5 is arranged on the base 1 and is used to adjust the lifting mechanism 4 in the horizontal direction. The adjustment mechanism 5 includes an adjustment block 51 and an adjustment rod 52. The adjustment block 51 is arranged on the lower end surface of the bottom plate 41. The adjustment rod 52 is rotatably connected to the base 1 and is threadedly connected to the adjustment block 51.

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the calibration mechanism 6 is disposed on the shooting platform 3 and is used to realize the center calibration of the nozzle on the shooting platform 3 . The calibration mechanism 6 includes a support frame 61 , a slider 62 , a spring 63 and a display assembly 64 .

[0024] like Figure 3 , Figure 4 , Figure 5 As shown, the support frame 61 is arranged on the outer wall of the shooting platform 3, and the support frame 61 includes a fixed ring 611, a sliding ring 612, a support rod 613 and a driving rod 614. The fixed ring 611 is arranged on the outer wall of the shooting platform 3, and the sliding ring 612 is slidably connected to the outer wall of the shooting platform 3 and is located behind the fixed ring 611. Four support rods 613 are rotatably connected to the surrounding of the fixed ring 611, and the support rods 613 are arranged in an inclined surface after rotation. The driving rod 614 is rotatably connected to the support rods 613 and the sliding ring 612, and is used to control the flipping of the support rods 613. A pair of magnets 615 are arranged at intervals on the outer wall of the shooting platform 3, and the pair of magnets 615 are respectively used to adsorb the two sides of the sliding ring 612.

[0025] like Figure 3 , Figure 4 , Figure 5 As shown, the slider 62 is slidably connected to the inclined position of the support rod 613, and the upper end surface is flat and used to resist the inner wall of the center hole of the fixed template 7. The spring 63 is arranged in the support frame 61 and is used to push the slider 62 to slide outward.

[0026] like Figure 6 As shown, a locking piece 65 is rotatably provided at the lower end of the slider 62, a locking groove 616 for the locking piece 65 to be embedded is provided on the fixing ring 611, a connecting ring 617 is rotatably connected inside the fixing ring 611, a locking rod 618 for inserting the locking piece 65 is provided on the connecting ring 617, and a handle 619 that passes through the outer wall of the fixing ring 611 is provided on the connecting ring 617.

[0027] like Figure 4 As shown, the display assembly 64 is used to display the sliding amount of the slider 62, and the display assembly 64 includes a lighting lamp 641, a light shielding plate 642 and a light-transmitting plate 643. The lighting lamp 641 is arranged at the inner end surface of the slider 62, the light shielding plate 642 is arranged on the support rod 613, and is used to shield the lighting lamp 641, and the light-transmitting plate 643 is arranged in two colors, namely red and blue, and the light-transmitting plates 643 are distributed on both sides of the light shielding plate 642, and the light of the lighting lamp 641 is transmitted.

[0028] When the center calibration of the shooting platform 3 is required, the connection position of the support rod 613 and the driving rod 614 is pulled upward, and then the sliding ring 612 is controlled to separate from the rear magnet 615 and approach the fixed ring 611. At this time, the support rod 613 is controlled to rotate synchronously with the cooperation of the driving rod 614. When the fixed ring 611 contacts the front magnet 615, the support rod 613 and the driving rod 614 are fixed.

[0029] During the rotation of the support rod 613, the support rod 613 drives the slider 62 to move synchronously until the position of the support rod 613 is fixed and the slider 62 is horizontal. Then, the shooting platform 3 is controlled to slide horizontally so that the shooting platform 3 passes through the center hole of the fixed template 7 on the injection molding machine.

[0030] Then the control handle 619 drives the connecting ring 617 to move synchronously, so that the connecting ring 617 drives the locking rod 618 to slide horizontally and disengage the locking piece 65. At this time, the locking piece 65 is unlocked, and then under the elastic force of the spring 63, the control slider 62 slides outward and makes the slider 62 contact the inner wall of the center hole of the fixed template 7.

[0031] During the sliding process of the slider 62, the slider 62 drives the illuminating lamp 641 to move synchronously. At this time, the light of the illuminating lamp 641 is irradiated outwards. Then, the support rod 613 is observed. If no light is transmitted, it means that the slider 62 is at the position of the light shielding plate 642, which proves that the distance between the outer wall of the shooting platform 3 and the center hole of the fixed template 7 is the accurate distance. If red light is transmitted, it means that the distance between the outer wall of the shooting platform 3 and the center hole of the fixed template 7 is close. If blue light is transmitted, it means that the distance between the outer wall of the shooting platform 3 and the center hole of the fixed template 7 is far.

[0032] Therefore, by observing whether there is colored light coming out, it is possible to determine whether the position of the shooting platform 3 is accurate, and then the position of the shooting platform 3 can be adjusted. When no light comes out from the four support rods 613, the accurate adjustment of the position of the shooting platform 3 can be achieved.

[0033] When adjusting the height position of the shooting platform 3, the bidirectional screw 44 is controlled to rotate. At this time, the bidirectional screw 44 controls a pair of connecting blocks 43 to move closer to or farther from each other. At this time, the connecting blocks 43 drive the lifting rod 45 to move synchronously. At this time, the lifting rod 45 flips and controls the bottom plate 41 and the top plate 42 to move away from or closer to each other, thereby realizing the adjustment of the height position of the shooting platform 3 according to the adjustment requirements.

[0034] When adjusting the horizontal position of the shooting platform 3, the adjusting rod 52 is controlled to rotate. At this time, the adjusting rod 52 controls the adjusting block 51 to slide horizontally. The adjusting block 51 drives the entire lifting mechanism 4 to slide horizontally. The lifting mechanism 4 drives the shooting platform 3 to move synchronously, thereby realizing the adjustment of the horizontal position of the shooting platform 3 according to the adjustment requirements.

[0035] When the center position of the shooting platform 3 is calibrated, the control handle 619 drives the connecting ring 617 to move in the opposite direction synchronously, so that the connecting ring 617 drives the locking rod 618 to slide horizontally, and then the slider 62 is controlled to slide inward, so that the locking piece 65 on the slider 62 is embedded in the locking groove 616 on the fixing ring 611, and then the connecting ring 617 is controlled to drive the locking rod 618 to insert the locking piece 65, so as to realize the limited fixation of the slider 62.

[0036] Then the sliding ring 612 is controlled to separate from the front magnet 615 and away from the fixed ring 611. At this time, the support rod 613 is controlled to rotate synchronously with the cooperation of the driving rod 614. When the fixed ring 611 contacts the front magnet 615, the support rod 613 and the driving rod 614 are turned over, stored and fixed to prevent the operation of the shooting platform 3 from being affected.

[0037] Therefore, the spring 63 is used to push the slider 62 to contact the inner walls around the central hole of the fixed template 7, and the display component 64 is used to display the sliding amount of the slider 62 in real time. At the same time, during the process of adjusting the position of the shooting platform 3 by the lifting mechanism 4 and the adjustment mechanism 5, the display component 64 always displays the sliding amount of the slider 62 in real time, which is convenient for center calibration. The entire process does not require the use of a vernier caliper for measurement, and the position of the shooting platform 3 can be accurately and quickly adjusted.

[0038] like Figure 3 As shown, the outer wall of the shooting platform 3 is rotatably connected with four recording rings 31 in parallel, and the outer wall of the recording ring 31 is provided with a digital sheet 32. A protective plate 33 covering the recording ring 31 is provided on the shooting platform 3, and the protective plate 33 is provided with four through holes 34 for the digital sheet 32 ​​to pass through.

[0039] Therefore, by providing a rotatably connected recording ring 31 on the shooting platform 3, the operator can rotate the recording ring 31 to allow different digital sheets 32 to pass through the through holes 34, thereby recording the maintenance date and facilitating regular center calibration of the shooting platform 3.

[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
