[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] Reference Figure 1-3 As shown,

[0022] A road cone machine mold opening structure includes a bracket 1, a lifting mechanism 2 installed on the bracket 1, and a supporting component 3 that cooperates with the lifting mechanism 2 to lift the road cone. The supporting component 3 is used to contact the road cone and cooperate with the lifting component to lift the road cone to demould. The lifting mechanism 2 includes

[0023] The screw rod 21 is rotatably connected to the bracket 1;

[0024] The driving mechanism 22 is fixedly connected to the bracket 1 and linked with the screw rod 21 to drive the screw rod 21 to rotate;

[0025] The actuator 23 is fixedly connected to the supporting component 3 and is connected to the screw rod 21 to form a match. When the screw rod 21 rotates, the actuator 23 is driven to rise or fall.

[0026] In this solution, the drive mechanism 22 drives the screw rod 21 to rotate, and the rotation of the screw rod 21 is used to drive the actuator 23 to move along the screw rod 21, and then move with the supporting component 3, and use the supporting component 3 to move the product on the mold, so that the product is separated from the mold and demolding is achieved. In this action, after demolding, the screw rod 21 can be driven in the reverse direction to rotate, so that the actuator 23 moves downward, and the supporting component 3 puts the product into the mold again, and the next mold is conveyed to the demolding position through the conveyor belt. The demolded mold can be moved to other workstations for the staff to take out the product.

[0027] The screw rod 21 and the actuator 23 cooperate to form a ball screw, which is driven by the principle of the ball screw.

[0028] This driving method can make the supporting component 3 move faster, thereby accelerating the demoulding efficiency and improving the production efficiency. Moreover, compared with the method of matching the oil cylinder and the optical axis, this driving method has a large driving stroke and will not significantly increase the height of the overall equipment due to the need to provide optical axis contraction space for the expansion and contraction of the oil cylinder.

[0029] In the preferred solution, the number of the lead screw and the actuator 23 is two, which are evenly distributed on both sides of the supporting component 3, so that the lifting and lowering of the supporting component 3 can be more stable. At the same time, based on this solution, the following settings can be further made: the driving mechanism 22 includes a motor 221 fixedly connected to the bracket 1, a transmission wheel 222 coaxially fixed with the lead screw 21, and a chain 223; the motor 221 and the two transmission wheels 222 are synchronously linked through the chain 223.

[0030] After starting, the motor 221 can cooperate with the chain 223 for transmission. For example, the output shaft of the motor 221 is fixedly connected to the flywheel, and the flywheel is engaged with the chain 223 to drive the chain 223 for transmission. During the transmission process, the chain 223 can synchronously drive the two transmission wheels 222 to rotate. At this time, the two screw rods 21 can be in a synchronous rotation state. As long as the specifications of the transmission wheels 222 are the same, the screw rods 21 can be ensured to be in synchronous transmission and the transmission speed is the same. At this time, the driving states of both sides of the supporting component 3 can be ensured to be the same, the movement is more stable, and the equipment operation is also more stable.

[0031] Of course, this solution is implemented based on the situation that there are two screw rods 21 and actuators 23, and can also be implemented in the situation that there is only one screw rod 21 and actuator 23. In this case, the screw rod 21 and actuator 23 can be located in the middle of the bracket 1 or the supporting component 3. That is, the driving mechanism 22 includes a motor 221 fixedly connected to the bracket 1, a transmission wheel 222 coaxially fixed with the screw rod 21, and a chain 223; the motor 221 and the transmission wheel 222 are linked by the chain 223.

[0032] In order to make the movement of the supporting component 3 more stable, a plurality of guide rods 4 are vertically arranged on the bracket 1, and the guide rods 4 penetrate the supporting component 3 and are slidably connected to the supporting component 3.

[0033] The setting of the guide rod 4 can make the supporting component 3 have sliding positioning in multiple directions, making its sliding more stable. Figure 1 , 2 As shown in , the number of the guide rods 4 can be four, which are respectively located at the four corners of the supporting component 3 to guide the sliding direction of the supporting component 3.

[0034] Specifically, one end of the actuator 23 is fixedly connected to the supporting component 3 , and the other end is connected to the connecting plate 5 . The guide rod 4 penetrates the connecting plate 5 and is slidably connected to the connecting plate 5 .

[0035] The actuator 23 needs to ensure that it does not rotate, and needs to cooperate with the rotation of the screw rod 21 to produce axial displacement. At this time, the connecting plate 5 can act as a component to limit the axial rotation of the actuator 23. The connecting plate 5 is fixed to the actuator 23 and is also slidably connected with the guide rod 4. It can limit the rotation of the actuator 23 while further putting the actuator 23 in a more stable state.

[0036] In addition, refer to Figure 1 As shown in FIG, the screw rod 21 is sleeved with a bellows protective sleeve 6. The bellows protective sleeve 6 can have compression and recovery functions, refer to Figure 1 The number of bellows protective sleeves 6 shown in the figure can be two, which are respectively located above and below the supporting component 3 and are both sleeved on the screw rod 21. Of course, if there are two screw rods 21, the number of bellows protective sleeves 6 is four. This solution can protect the screw rod 21 and prevent other debris and particles from entering the screw rod 21, causing problems in the coordination between the screw rod 21 and the actuator 23, and even causing abnormal operation of the actuator 23 and the screw rod 21 on one side, and the operation of the two sides is out of sync, which affects the life of the equipment.

[0037] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
