[0027] Reference Figures 1 to 5 The injection molding rotating seat of the utility model is made into the following embodiments:

[0028] An injection molding rotating seat comprises: a shooting platform mounting seat 100 and a rotating seat cylinder 200.

[0029] The shooting platform mounting seat 100 is arranged above the rotating seat cylinder 200. The rotating seat cylinder 200 has a cylindrical connecting cavity 210 extending up and down. The lower side of the shooting platform mounting seat 100 has a cylindrical rotating shaft 110. The rotating shaft 110 is coaxially rotatably arranged in the connecting cavity 210.

[0030] In actual use, the rotating seat cylinder 200 is fixedly arranged on the frame of the injection molding equipment, and the injection molding screw is installed on the shooting platform mounting seat 100. The shooting platform mounting seat 100 and the rotating seat cylinder 200 are rotationally connected through the rotating shaft 110 and the connecting cavity 210, so that the shooting platform mounting seat 100 can rotate relative to the rotating seat cylinder 200. When it is necessary to disassemble and maintain the injection molding screw, the shooting platform mounting seat 100 is rotated so that the injection molding screw thereon can be rotated to the side facing the injection molding machine, which is convenient for the operation of disassembling the screw. During normal injection molding, the shooting platform mounting seat 100 can rotate the injection molding screw thereon to the injection molding feed direction to realize normal injection molding processing. The shooting platform mounting seat 100 that can rotate relative to the rotating seat cylinder 200 reduces the retreat distance of the shooting platform and saves the use space of the injection molding machine.

[0031] In order to avoid the inconvenience of rotation caused by the excessive weight of the shooting platform mounting seat 100 and the shooting platform thereon, in this embodiment, the shooting platform mounting seat 100 and the rotating seat cylinder 200 are connected by air floating rotation. The rotating shaft 110 and the connecting cavity 210 are connected by rotation sealing. The rotating shaft 110 has a hollow air storage cavity 120. The lower end of the air storage cavity 120 has an opening 121. The rotating seat cylinder 200 has an air inlet hole 220 connected to the air storage cavity 120.

[0032] When the direction of the shooting platform mounting seat 100 needs to be rotated, high-pressure gas is introduced into the gas storage chamber 120 through the air inlet hole 220, so that the gas pressure can act on the shooting platform mounting seat 100 and the rotating seat cylinder 200, providing the shooting platform mounting seat 100 with an upward buoyancy relative to the rotating seat cylinder 200, thereby reducing the friction resistance between the shooting platform mounting seat 100 and the rotating seat cylinder 200, and making the rotation easier and smoother.

[0033] In some other embodiments, the air inlet hole 220 may be disposed at the bottom of the rotating seat cylinder 200, and the air inlet hole 220 is aligned with the opening 121 and communicated with the air storage chamber 120. In order to avoid obstruction to the installation of the rotating seat cylinder 200, in this embodiment, the air inlet hole 220 is disposed on the side wall of the rotating seat cylinder 200. An annular air inlet groove 111 is disposed on the outer side of the rotating shaft 110. The air inlet groove 111 is provided with a first communication hole 130 communicated with the air storage chamber 120. One end of the air inlet hole 220 is communicated with the outer side of the rotating seat cylinder 200, and the other end of the air inlet hole 220 is aligned with and communicated with the air inlet groove 111.

[0034] When the shooting platform mounting seat 100 rotates relative to the rotating seat cylinder 200, the air inlet hole 220 can always be aligned with the air inlet groove 111, so as to achieve the communication between the air inlet hole 220 and the air storage chamber 120. A plurality of the first communicating holes 130 can be provided. A plurality of the first communicating holes 130 can make the inflation and pressurization process faster. A plurality of the first communicating holes 130 are evenly distributed around the circumference of the air inlet groove 111.

[0035] The upper end of the rotating shaft 110 is dynamically sealedly connected to the connecting cavity 210. An annular sealing groove 112 is provided on the outer side of the upper portion of the rotating shaft 110. An annular sealing ring is inserted in the sealing groove. The sealing ring protrudes from the outer side surface of the rotating shaft 110 and is tightly abutted against the inner wall of the connecting cavity 210, thereby realizing the dynamic sealing connection between the rotating shaft 110 and the connecting cavity 210.

[0036] Furthermore, an air floating gap 230 is provided between the outer wall of the rotating shaft 110 and the inner wall of the connecting cavity 210. The rotating shaft 110 is provided with a second connecting hole 140 connecting the air floating gap 230 and the gas storage cavity 120. After the high-pressure gas is filled into the gas storage cavity 120, it can be filled into the air floating gap 230 through the second connecting hole 140, forming an air cushion between the outer wall of the rotating shaft 110 and the inner wall of the connecting cavity 210, reducing the friction between the outer wall of the rotating shaft 110 and the inner wall of the connecting cavity 210, making the relative rotation of the shooting platform mounting seat 100 and the rotating seat cylinder 200 easier.

[0037] In this embodiment, the air inlet groove 111 is disposed at the lower portion of the rotating shaft 110. The air floating gap 230 is disposed at the middle portion of the rotating shaft 110, and the air floating gap 230 is disposed between the air inlet groove 111 and the sealing ring.

[0038] In order to ensure that the shooting platform mounting seat 100 can be relatively fixed with the rotating seat cylinder 200 during normal use and is not prone to deflection, a limiting mechanism for relatively fixing the shooting platform mounting seat 100 and the rotating seat cylinder 200 is provided between the shooting platform mounting seat 100 and the rotating seat cylinder 200.

[0039] In this embodiment, the limiting mechanism includes a limiting clamping plate 250. The side of the shooting platform mounting seat 100 has a positioning surface 150. The positioning surface 150 is perpendicular to the radial direction of the rotating shaft 110. The rotating seat cylinder 200 is provided with a limiting surface 240. The limiting surface 240 is perpendicular to the radial direction of the connecting cavity 210. The central axis of the rotating shaft 110 and the connecting cavity 210 are coaxially arranged, and the spacing between the positioning surface 150 and the limiting surface 240 and the central axis is consistent. The limiting clamping plate 250 is rotatably arranged on the limiting surface 240.

[0040] In actual use, the positioning surface 150 is arranged on the upper side of the limiting surface 240. The positioning surface 150 is arranged along the moving direction of the shooting platform, and the limiting surface 240 is arranged along the injection feeding direction. When the shooting platform mounting seat 100 rotates to face the screw feeding direction, the positioning surface 150 is flush with the limiting surface 240, and the limiting clamping plate 250 can rotate on the limiting surface 240. A part of the positioning clamping plate rotates to overlap and press against the positioning surface 150, so that the shooting platform mounting seat 100 and the rotating seat cylinder 200 can remain relatively fixed.

[0041] The limit clamping plate 250 has a hinged end 251 and a slot 252. The slot 252 extends from the edge of the limit clamping plate 250 along the circumference of the hinged end 251. The hinged end 251 is rotatably hinged with the limit surface 240. The limit surface 240 is also provided with a limit bolt 241 corresponding to the slot 252. The rotation axis 110 line of the hinged end 251 is perpendicular to the limit surface 240, and the limit bolt 241 is parallel to the rotation axis 110 line of the hinged end 251. The spacing between the limit bolt 241 and the slot 252 and the hinged end 251 is consistent.

[0042] When the limiting clamping plate 250 rotates around the hinge end 251 and flips over to partially overlap the positioning surface 150, the clamping groove 252 can be sleeved outside the limiting bolt 241. The limiting clamping plate 250 can be locked and fixed by the limiting bolt 241 to fix the shooting platform mounting seat 100.

[0043] In this embodiment, an adjustment fixing seat 260 is provided on the left side and / or right side of the rotating seat cylinder 200. Two adjustment bolts extending forward and backward and arranged opposite to each other are respectively threadedly provided at the front and rear ends of the adjusting fixing seat 260. The rotating seat cylinder 200 has an adjustment portion provided between the two adjustment bolts. When installing the injection molding rotating seat, the adjustment fixing seat 260 is first fixedly installed on the frame of the injection molding equipment, and then the rotating seat cylinder 200 is installed and fixed, and the front and rear positions of the rotating seat cylinder 200 are adjusted by the two adjustment bolts.
