The two sides of the first supporting mechanism 12 are fixedly connected with a first supporting frame 2 and a second supporting frame 3 respectively. In the present embodiment, the first support frames 2 and 3 and the first support mechanism 12 constitute a U-shaped support mechanism. The outer side of the first support frame 2 and/or the second support frame 3 is provided with a rotary connecting part 4. The rotation connection 4 drives the cradle to swing. The rotation connecting part 4 is rotatably connected with a supporting device provided with a motor drive, one of the rotation connecting parts 4 can be selected to be provided with two gears, and the support swinging or the first supporting part 11 rotating is realized through the driving gear. How the rotation connecting portion 4 drives the bracket to swing or the first supporting portion 11 to rotate is prior art, and is not described in detail in the application.
As shown in fig. 2 and 3, in order to reduce the pressure of the first support part 11 and make the plastic more uniform in rotational molding, the second support assembly 5 is fixedly connected between the first support frame 2 and the second support frame 3 in the present embodiment. In the embodiment, the second supporting component 5 is preferably composed of a plurality of steel rods, and the shape of the second supporting component 5 is not limited as long as the rotational motion of the rotational molding die 100 about the first supporting portion 11 can be resisted and the rotational motion of the rotational molding die 100 during the swinging process can not be hindered.
The second support member 5 is provided with a rolling abutment 6. The rolling abutment 6 comprises a central shaft 61 and a rolling member 62, the rolling member 62 being fitted over the central shaft 61. The outer side surface of the rolling contact part 6 can be an arc or a corrugated part with a certain radian and a plurality of edges, or a plurality of rollers can be sleeved on the central shaft 61 to form the rolling contact part 6. In the present embodiment, the rolling contact portion 6 is preferably a roller.
The stent state of this embodiment is such that: when the rotating connecting part 4 drives the bracket to swing, the rolling abutting part 6 abuts against the outer side face of the rotational molding die 100; when the first supporting portion 11 drives the rotational molding die 100 to rotate together, the rolling contact portion 6 contacts with the outer side surface of the rotational molding die 100 and can generate relative displacement. For optimal support effect, the rolling abutment 6 of the present embodiment always abuts against the rotomoulding mould 100. When the rotational molding die 100 swings, the rolling abutment 6 abuts against the rotational molding die 100, and the rolling abutment 6 does not rotate. When the rotational molding die 100 rotates, the rolling abutment portion 6 abuts against the rotational molding die 100 and rotates when the rotational molding die 100 rotates.
The second support member 5 is provided with a drive mechanism 7 for driving the rolling abutment 6 towards or away from the rotational moulding mould 100.

The driving mechanism 7 comprises a driving connection device and a driving source; the driving connecting device is fixedly connected with the top or the bottom of the rolling contact part 6; the driving source is movably connected with the driving connecting device.
As shown in fig. 3, the number of the driving connection means of the present embodiment is two; a drive connection device is fixedly connected with the top of the rolling contact part 6; the other driving connecting device is fixedly connected with the bottom of the rolling contact part 6; one drive source is connected to each drive connection.
As shown in fig. 4, the driving connection device includes a sliding member 71, a sliding rail 72; the sliding member 71 is fixedly connected to one end of the central shaft 61; the slide rail 72 is fixedly connected with the second support component 5; the sliding piece 71 is connected with the sliding rail 72 in a sliding way; the driving connecting device also comprises a bearing 63, a spacer 64, a round nut stop washer 65, a round nut 66 and a bearing cover 67; the bearing 63 is installed between the slider 71 and the center shaft 61; the central shaft 61 is sequentially provided with a spacer 64, a round nut stop washer 65 and a round nut 66 in the direction from far away from the rolling member 62 to near the rolling member 62; a bearing cap 67 is mounted on the outer side of the slider 71. The driving connecting device is fixedly connected with the rolling contact part 6, so that the driving source can control the position of the rolling contact part 6 conveniently through the driving connecting device.
As shown in fig. 4, the driving mechanism further includes a first blocking plate 73, an adjusting screw 74 and a limiting nut 75, the first blocking plate 73 is fixed at the end of the sliding rail 72; the adjusting screw 74 penetrates through the first baffle 73, one end of the adjusting screw 74 is fixedly connected with the driving connecting device, and the limiting nut 75 is in threaded connection with the other end of the adjusting screw 74. In this embodiment, when the position of the rolling contact part 6 needs to be adjusted, the position-limiting nut 75 needs to be loosened, the adjusting screw 74 is pushed until the rolling contact part 6 abuts against the outer side surface of the rotational molding die 100, and finally the position-limiting nut 75 needs to be tightened to make the position-limiting nut 75 tightly abut against the first baffle 73. Thus during oscillation, the weight of the rotomoulding mould 100 has a force on the rolling abutment 6 towards the first flap 73 that counteracts the locking force between the limit nut 75 and the adjusting screw 74. This serves as a catch for the rolling abutment 6.
As shown in fig. 2 and 3, the second support member 5 is provided with at least two rolling abutments 6 arranged opposite to each other. All the rolling contact parts 6 on the second support component 5 are matched to form a contact stable area 9, so that the pressure born by each rolling contact part 6 is consistent, and the plastic in the rotational molding die 100 can be more uniform. Preferably, in the present embodiment, 4 rolling contact portions 6 are provided on the second support assembly 5, and the 4 rolling contact portions 6 are uniformly circumferentially distributed on the second support assembly 5.
As shown in fig. 3, the second support member 5 detachably connects the first support frame 2 and the second support frame 3. The first support frame 2 and the second support frame 3 are both provided with mounting areas, and a plurality of mounting holes are distributed at intervals between the highest position and the lowest position of the mounting areas; the second support member 5 is mounted on the mounting region by the engagement of screws with the mounting holes. Therefore, the position of the second supporting component 5 between the first supporting frame 2 and the second supporting frame 3 can be adjusted, namely, the height of the second supporting component 5 is adjusted, and the rotational molding die 100 is suitable for rotational molding dies 100 with different heights and is convenient to use. A triangular stabilizing area 8 is arranged at the joint of the second supporting component 5 and the first supporting frame 2 or the second supporting frame 3. The triangular stabilizing zone 8 reinforces the strength of the second support member 5.
