The present invention provides a linked blow molding apparatus for a rotary blow molding machine and a method of operating the same, which is related to the structure of the blow molding apparatus.

The apparatus for performing blow molding in the blow molding process is a blow molding machine, as shown in Figs. 1 and 2, which is a blow molding apparatus disclosed in U.S. Patent No. 8,100,688, which is mainly a blow molding apparatus 10 A drive shaft 12 is pivotally disposed on a fixed support base 11, and a fixed die 13 is further fixed on the support base 11, and a movable die 14 pivotable relative to the fixed die 13 is fixed. The bottom side of the die 13 is further provided with a cam groove 131. At the same time, the drive shaft 12 is coupled to the movable die 14 through a first link set 15 perpendicular to the drive shaft 12, and transmits a direction different from the drive shaft 12. The second link set 16 is coupled to a bottom mold 17, and the bottom mold 17 is further coupled to a cam 171. The cam 171 of the bottom mold 17 is movably received in the cam groove 131; thereby, the drive shaft 12 rotates. The movable mold 14 is pivoted relative to the fixed mold 13 and the bottom mold 17 is driven by the first link set 15 and the second link set 16 to make the bottom mold 17 follow the cam 171 along the cam. The groove 131 is raised and lowered to complete the simultaneous movement of the left and right opening and closing molds and the bottom mold lifting and lowering; Blow molding apparatus 10 through the main drive shaft 12 to rotate with two different direction of the extension linkage 15 and 16 produce driving the movable mold opening mold, a bottom mold driving operation of the lift, the vertical drive shaft 12 The two sets of connecting rod sets 15, 16 will become the weakness of the overall structure, and both ends of the two connecting rod sets 15, 16 are connected to the driving shaft 12, the movable mold 14 and the bottom mold 17 in a pivotable manner. Each pivot point is critical to the smoothness, accuracy and efficiency of the overall movement. The structural accuracy and quality requirements of the overall device are high and difficult to control accurately. Therefore, it is difficult to assemble, the device cost is high, and the accuracy is difficult to control. In addition, as shown in FIGS. 3 and 4, the US Patent Publication No. US20120177771A1, "Blow Molding Apparatus", is mainly provided with a fixed mold 22 fixedly disposed on a fixed platform 21 side. The other side is provided with a column 211 and a bottom mold 23, and the platform 21 is further provided with a first rotating shaft 24 and a second rotating shaft 25. The first rotating shaft 24 is coupled to a movable mold 26 through a first connecting block 241. The outer surface of the movable mold 26 has a vertical angle resisting recess 261, and the first connecting block 241 is further coupled to the second fixed shaft 25 through a connecting rod 27 perpendicular to the extending direction of each of the rotating shafts 24, 25. Two connecting blocks 251, and the connecting rod 27 Both ends are coupled in a pivotal manner, and the second rotating shaft 25 is further connected with a pair of resisting blocks 252 which should be shaped to resist the concave portion 261; thereby, the movable mold 26 and the fixed mold 22 are to be opened and closed. When the bottom mold 23 is moved up and down, it is necessary to drive the bottom mold 23 to be lifted and lowered by a lifting drive source that drives the bottom mold 23 to move up and down, and the driving source that drives the rotation of the first rotating shaft 24 to drive the first rotating shaft 24 to rotate, and the overall structure is The first rotating shaft 24 is rotated to drive the first connecting block 241 and the movable mold 26 to pivot and generate the opening and closing action, and is coupled to the first connecting block 241. The connecting rod 27 also acts to drive the second connecting block 251 to move, and the second connecting block 251 drives the second rotating shaft 25 and the resisting block 252 thereon to generate a pivoting action, when the movable mold 26 generates a clamping motion. The resisting block 252 is also actuated at the same time and is pressed against the resisting recess 261 of the movable mold 26 when the mold clamping operation is completed. The resisting block 26 is stably resisted by the resisting block 252 to withstand blowing. The tension applied to the movable mold during the film process ensures the processing precision and the yield; however, the "blow molding apparatus" of the US Pat. No. US20120177771A1 has two sets of driving sources which are required to have a lifting and opening and closing mold in addition to the overall complicated structure. In addition to the high cost, the overall structure must have a connecting rod 27 perpendicular to the extending direction of each of the rotating shafts 24, 25 in addition to the respective rotating shafts 24, 25 to drive the resisting block 252, which is different from the respective rotating shafts 24, 25. The connecting rod 27 of the direction is arranged as a weak point of the overall structure, and the connecting ends of the connecting rod 27 are pivotally connected. The structural precision and quality requirements of the overall device are the same as those of the prior art, and it is difficult to accurately control, and the assembly difficulty is difficult. The high cost of the device, the high cost of the device, and the difficulty in controlling the lack of improvement; further, as shown in Figures 5 and 6, the German Patent No. DE 10 2008 045 569 A1 "Blow Molding Apparatus", the blow molding apparatus 30 is mainly through a The driving source 31 drives a control member 32 to rotate. The control member 32 has a first cam portion 321 and a second cam portion 322, and the control member 32 is further connected through a connecting rod 33. The engaging member 34 has a first roller member 341 and a second roller member 342 that abut against the outer periphery of the first cam portion 321 and the second cam portion 322. The other side of the opening and closing driving member 34 pivots the first driving rod 343 and the second driving rod 344, and the first driving rod 343 and the second driving rod 344 are respectively coupled to a forming die 35, 36; Thereby, the driving source 31 drives the control member 32 to rotate. When the control member 32 rotates, the first cam portion 321 and the second cam portion 322 rotate synchronously, and the first roller member 341 and the second portion are rotated. The position of the roller member 342 against the first cam portion 321 and the second cam portion 322 is changed correspondingly, and the configuration of the first cam portion 321 and the second cam portion 322 is transmitted to drive the opening and closing of the driving member 34. The position of the first driving rod 343 and the second driving rod 344 can be changed simultaneously while the opening and closing driving member 34 is displaced, thereby driving the first driving rod 343 and the second driving rod 344. The forming dies 35, 36 generate an opening and closing action; It can be seen that although the patent "Blow Molding Equipment" of German Patent No. DE102008045569A1 can achieve the purpose of driving the opening and closing mold, it is still unable to drive the bottom mold to lift and complete the mold clamping action on the same mechanism, and there is still room for improvement. In addition, the control member of the blow molding apparatus 30 must be driven to rotate relative to the first driving rod 343 and the second driving rod 344 in addition to being driven by the opening and closing driving member. When the action is completed, the action of the opening and closing of the driving member to drive the opening and closing mode is indirect driving, and the non-direct driving mode will result in the reduction of the overall operational efficiency and the difficulty of the operation precision control; It can be seen that each blow molding equipment still has the lack of operational precision, complicated structure or low operational efficiency. In view of this, the inventors have devoted themselves to research and further conceived, and after many trials and developments, finally invented a linkage type. Blow molding device.

The invention provides a linked blow molding device for a rotary blow molding machine, the main purpose of which is to improve the lack of operation precision, complicated structure or low operational efficiency of the conventional blow molding device.

To achieve the foregoing objective, the present invention provides a linked blow molding apparatus for a rotary blow molding machine, comprising: a support base pivotally provided with a power input shaft and a mold control shaft, the power input shaft and the The mold control shafts each extend along an axial length; a drive source drives the power input shaft and the mold control shaft to rotate; and a forming die includes a first movable member pivotally disposed on the support base a mold core and a second movable mold core, the forming mold being controlled by the mold control shaft to pivot the first movable mold core and the second movable mold core relatively close to or away from each other; the opening and closing momentum of the forming mold is driven a bottom mold The unit is axially displaced, and drives a clamping unit to lock the first movable mold core and the second movable mold core.

For the same purpose as described above, the present invention further provides a method for operating a linked blow molding apparatus of a rotary blow molding machine, which is driven by a single driving source to sequentially generate a forming mold opening and closing step, a bottom mold lifting step, and a mold clamping method. And a step of opening and closing, wherein: the forming and opening and closing step of the forming die is that a first movable mold core and a second movable mold core of a forming mold are pivoted relatively close to or away from each other; and the bottom mold lifting step is a bottom mold unit lifting displacement And the mold clamping opening and closing step is a clamping unit locking the first movable mold core and the second movable mold core.
