DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0029] like Figure 1 As shown, a mold platform lifting mechanism provided in this embodiment includes a base plate 1, a lifting drive member 2, a roller 3, a first support 4, a second support 5, a sensor bracket 6 and a sensor 7.

[0030] The base plate 1 is provided with through holes around its periphery for passing anchor bolts to fix it to the production line floor.

[0031] like Figure 2 As shown, the lifting drive member 2 comprises a first flange plate 21, a cylinder 22 and a second flange plate 23. The first flange plate 21 is fixed to the bottom of the cylinder barrel of the cylinder 22, and the second flange plate 23 is fixed to the top of the telescopic rod of the cylinder 22.

[0032] like Figure 1As shown, the first support 4 includes two first side walls 41 spaced apart and a second side wall 42 connected between the two ends of the two first side walls 41. The two first side walls 41 and the two second side walls 42 enclose a hollow structure with two ends penetrating. The area of ​​the first side wall 41 is larger than the area of ​​the second side wall 42. A maintenance hole 43 is provided on the side wall of the first side wall 41 close to the base plate 1. The maintenance hole 43 is a large square hole. The first flange plate 21 is fixed to the base plate 1 by bolts and can be operated through the maintenance hole 43.

[0033] like Figure 3 , Figure 4 As shown, the second support 5 includes a bottom plate 53, a guide block 54, two third side walls 51 spaced apart, and a fourth side wall 52 connected between the two ends of the third side walls 51. The two third side walls 51 and the two fourth side walls 52 are enclosed to form a hollow structure with two ends through, and the bottom of the hollow structure is sealed with the bottom plate 53. The bottom plate 53 is provided with a through hole (such as Figure 4 As shown), the second flange plate 23 is provided with a through hole or a threaded hole corresponding to the through hole on the bottom plate 53, so that the bottom plate 53 and the second flange plate 23 can be connected by bolts.

[0034] The central axis of the roller 3 is rotatably arranged on the third side wall 51 through a bearing. The guide block 54 is arranged on both the third side wall 51 and the fourth side wall 52. The area of ​​the third side wall 51 is larger than the area of ​​the fourth side wall 52, so that two guide blocks 54 are arranged on the third side wall 51 and one guide block 54 is arranged on the fourth side wall 52. The guide block 54 is in sliding contact with the inner wall of the first support 4. And the guide block 54 extends in the height direction of the third side wall 51 and the fourth side wall 52. And chamfers (rounded corners or edge chamfers) are arranged on the two ends of the guide block 54.

[0035] The oil cylinder 22 is raised and lowered to drive the second support 5 and the roller 3 thereon to slide up and down to form an upper position (such as Figure 5 as shown) and the lower position (as Figure 6 As shown in Figure 1 , Figure 5 , Figure 6 As shown, a sensing hole 44 is provided on one of the first side walls 41, and two sensors 7 are installed at the sensing holes 44 through the sensor bracket 6, and the sensor bracket 6 is fixed to the first side wall 41. The two sensors 7 respectively sense the upper position and the lower position of the roller 3. The sensor 7 is a travel switch, which is electrically connected to the oil cylinder 22 through the control system. Thus, the lifting state of the mold table is judged.

[0036] like Figure 7As shown, in the initial position, the roller 3 on the mold platform lifting mechanism 20 is at the same height as the assembly line roller. When the mold platform 10 moves on the above-mentioned mold platform lifting mechanism 20, the oil cylinder 22 is started to extend to push the second support 5 and the roller to rise. When it rises to the upper position and triggers the sensor 7, the control system receives the signal and sends a control command to control the oil cylinder 22 to stop moving. At this time, the mold platform 10 is lifted to the required height position, and the roller 3 on the mold platform lifting mechanism 20 exceeds the assembly line roller. When the operation content is completed, the oil cylinder 22 is started to descend. When it descends to the lower position and triggers the sensor 7, the control system receives the signal and sends a control command to control the oil cylinder 22 to stop moving. At this time, the roller 3 on the mold platform lifting mechanism 20 is at the same height as the assembly line roller, and then the mold platform 10 is controlled to leave the mold platform lifting mechanism 20.
