Embodiment Construction
[0020] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0021] see Figure 2-3 As shown, the protective device of the above-mentioned bottom mold support is located on the bottle blowing machine. The blow molding machine includes a frame and a bottom mold guide rail arranged on the frame, and the bottom mold support 2 is lifted and lowered on the frame. The bottom mold support 2 includes a bearing 4 arranged below it for moving along the bottom mold guide rail.
[0022] The protection device includes a fixed shaft 8 fixed on the bottom mold support 2 whose axis line is distributed along the horizontal direction, and a swing shaft arranged on the fixed shaft 8 whose axis line is radially distributed along the fixed shaft 8. 9. The bearing 4 is fixedly sleeved on the swing shaft 9 . The protection device also includes a detachable protection mechanism connected to the swing shaft 9 , and the prote...

Provided are a protection device for a bottom mold support (2) and a bottom mold support (2). The bottom mold support (2) is disposed at a bottle blowing machine. The bottle blowing machine comprises a mounting frame and a bottom mold guiding rail. The bottom mold support (2) is disposed at the mounting frame and is capable of vertical movement with respect to the mounting frame. The bottom mold support (2) comprises a bearing (4) disposed thereunder and movable along the bottom mold guiding rail. The protection device comprises a stationary shaft (8) fixed to the bottom mold support (2) and a rotary shaft (9) rotatably provided at the stationary shaft (8). The bearing (4) is securely disposed at the rotary shaft (9). The protection device further comprises a protection mechanism detachably connected to the rotary shaft (9). The protection mechanism is securely disposed at the bottom mold support (2). The invention is provided with the rotary shaft (9) capable of rotating around the stationary shaft (8) and the protection mechanism detachably connected to the rotary shaft (9), such that once an anomaly has occurred, the bearing (4) acted upon by a certain pressure causes the rotary shaft (9) to rotate and press a positioning member (11) to a positioning end cap (10). When the rotary shaft (9) rotates around the stationary shaft (8), the bearing (4) separates from the bottom mold guiding rail to protect a bottom mold of a molding tool or the bottom mold support (2), thereby effectively preventing parts from being damaged due to an anomaly.
Description
technical field [0001] The invention relates to a protection device for a bottom mold support. Background technique [0002] When the blow molding machine is in an abnormal state, the mold of the blow molding station is not opened, and at this time, the blow molding machine cannot be stopped in a short time. The bottom mold support is also driven by the bottle blowing machine to pull down the bottom mold along the bottom mold guide rail. This can cause damage to the mold counter or the counter support. [0003] see figure 1 As shown, in the traditional way, the large bracket 1 is installed on the main rotary mechanism of the bottle blowing machine, the bottom mold bracket 2 is connected to the large bracket 1 through guide rails and sliders, and the compression spring 3 provides an upward supporting force for the bottom mold bracket 2 , to ensure that the bottom mold support 2 can also lift up the mold bottom mold after the bearing 4 leaves the bottom mold guide rail, so ...
