The hydraulic cylinder 13 of the hot plate 12.

In general, if the material to be molded 102 is to be completely pressed against the mold clamping surface of the corresponding jig 101, the hydraulic cylinder 13 needs to provide a pressure of at least twenty tons or more, and when the material to be molded 102 is to be molded 102 When not formed in the jig 101, the hot plates 12 are liable to be tilted as shown in FIG. 2 due to the eccentric abutment of the jig during the lifting process, and the jig 101 will be slipped off in severe cases. Affect safety.

Therefore, the object of the present invention is to provide a lifting and anti-rolling type of a thermoforming machine which can prevent the hot plate from falling over when moving up and down. Set.

Therefore, the lifting and anti-tilting device of the novel thermoforming machine comprises a plurality of hot plates which are spaced apart and can be moved up and down along a reference axis, and are disposed under the hot plates and can be lifted in sequence The hydraulic cylinder of the isothermal plate, the lifting anti-tip device comprises a plurality of guiding pins, a plurality of supporting seats, and a plurality of elastic members.

The guide pins are disposed on opposite sides of the heat plate parallel to the reference axis.

The support seats are located on the hot plates and can be fixedly disposed by corresponding guide pins.

The elastic members are respectively sleeved on the guiding pins along the reference axis and are located between two adjacent and corresponding supporting seats.

The effect of the novel is that, by the arrangement of the elastic members, the force of the hot plates during the lifting movement can be balanced, thereby preventing the occurrence of the dumping phenomenon.

Other features and effects of the present invention will be apparent from the following description of the drawings. FIG. 1 is a schematic diagram showing the positional relationship of a conventional thermoforming machine in an unactuated state; FIG. 2 is a FIG. 3 is a schematic view showing a state in which a hot plate is tilted after the thermoforming machine is actuated; FIG. 3 is a schematic view showing a positional relationship of a first preferred embodiment of the lifting and anti-tilting device of the novel thermoforming machine; 4 is a schematic view showing the state of the plurality of hot plates of the first preferred embodiment when in operation; FIG. 5 is a schematic view showing the state of the hot plates of the first preferred embodiment after being actuated; 6 is a cross-sectional view taken along line VI-VI of FIG. 5; FIG. 7 is a schematic view showing the positional relationship of a second preferred embodiment of the present invention; and FIG. 8 is a line VIII-VIII along the line of FIG. a cross-sectional view.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals. In addition, it should be noted that the directions and positions described below are all based on FIG. 3 as a reference.

As shown in FIG. 3, FIG. 4 and FIG. 5, the lifting and anti-tilting device 3 of the novel thermoforming machine 2 is applicable to a plurality of jigs 201 capable of respectively holding a material 202 to be formed, and includes a plurality of jigs 201 a hot plate 21 which is spaced apart and can be moved up and down along a reference axis L and can be provided for the jigs 201, and a hydraulic pressure disposed under the hot plates 21 and capable of lifting the hot plates 21 in sequence The first preferred embodiment of the cylinder 22 includes a plurality of guide pins 31, a plurality of support seats 32, and a plurality of elastic members 33.

The guide pins 31 are disposed on opposite sides of the heat plate 21 parallel to the reference axis L. In addition to being the positioning members of the elastic members 33, the guide pins 31 can also serve as guide rails for lifting and lowering the hot plates 21. In the first preferred embodiment, the guide pins 31 are aligned along the reference axis. The support seats 32 are worn and the number is four. The guiding pins 31 can also be disposed on the adjacent hot plates 21 (not shown) in a vertically spaced manner and in pairs. At this time, the functions of the guiding pins 31 are the positioning members of the elastic members 33, and A separate guide rail is provided to assist the hot plates 21 to move up and down.

The support seats 32 are symmetrically disposed on the hot plates 21, respectively. And extending away from the reference axis L and located on opposite sides of the left and right sides of the hot plates 21. In the first preferred embodiment, the support bases 32 are four units and are respectively spaced and symmetrically disposed on the hot plates 21.

As shown in FIG. 6, the elastic members 33 are disposed along the reference axis L. And respectively disposed between two adjacent and corresponding support seats 32, that is, four elastic members 33 are respectively disposed between the two hot plates 21. In the first preferred embodiment, the elastic members 33 are compression springs.

As shown in FIG. 7 and FIG. 8, the lifting and lowering of the novel thermoforming machine 2 The second preferred embodiment of the anti-roll device 3 is similar to the first preferred embodiment in that only two elastic members 33 are disposed between the two hot plates 21, and the elastic members 33 are located in the heat. The same side of the board 21. In this state, when the jigs 201 are respectively mounted on the hot plates 21, since the high point A of the jig 201 is eccentrically disposed, only the elastic members 33 need to be installed on the hot plates. On the other side of 21, you can balance the forces and indeed avoid the occurrence of dumping.

Through the above structural composition, the advantages and effects of the present invention can be summarized as follows:

1. When the hydraulic cylinder 22 rises and drives the hot plates 21 to move upward, the hot plates 21 can be balanced by the arrangement of the elastic members 33. The force on the opposite side of the left and right sides does prevent the occurrence of dumping.

2. By providing the elastic members 33, it is possible to prevent the jigs 201 from colliding directly with the adjacent hot plates 21 when moving up and down. Thereby, the service life of the jigs 201 can be increased.

In summary, by the arrangement of the elastic members, the force of the hot plates can be balanced and the occurrence of the dumping phenomenon can be avoided, so that the object of the present invention can be achieved.

However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made in accordance with the scope of the present patent application and the contents of the patent specification, All remain within the scope of this new patent.
