DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The plastic template hot pressing forming device of the utility model embodiment is described below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, a plastic template hot pressing forming device comprises: a main mounting seat 1, a first mounting plate 2, a second mounting plate 3 and a motor mounting seat 4 are fixedly arranged at the lower part of the main mounting seat 1, two first connecting rods 5 are arranged below the main mounting seat 1, two second connecting rods 6 are arranged between the two first connecting rods 5, the first mounting plate 2 is arranged between the two second connecting rods 6, and the second mounting plate 3 is arranged between the two first connecting rods 5;

[0028] A slide bar 7 is provided on the first mounting plate 2, and the slide bar 7 is provided in the vertical direction. A slider 8 and a first spring 9 are provided on the slide bar 7, and the first spring 9 is used to drive the slider 8 to move upward. A trunnion 10 is provided on the slider 8, and a slide groove 11 is provided at one end of the second connecting rod 6, and the trunnion 10 is provided in the slide groove 11;

[0029] One end of the first connecting rod 5 is rotatably connected to the middle part of the second connecting rod 6 via a first rotating shaft 12, the other end of the second connecting rod 6 is provided with a second rotating shaft 13, one end of the second connecting rod 6 provided with the second rotating shaft 13 is connected to the second mounting plate 3 via a second spring 14, and the other end of the first connecting rod 5 is rotatably connected to the second mounting plate 3 via a third rotating shaft 15;

[0030] A motor 16 is disposed on the motor mounting seat 4 . A cam 17 is disposed on the rotating shaft of the motor 16 . The cam 17 is in contact with the second rotating shaft 13 .

[0031] Specifically, the relevant staff installs the plastic template hot pressing molding device at a suitable position on the production line, and installs a hot pressing mechanism on the slider 8.

[0032] When the plastic template hot pressing molding device is in an initial state, when the motor 16 is not started, the slider 8 is kept in the highest position under the action of the first spring 9, and the first connecting rod 5 and the second connecting rod 6 are in a relatively stable position.

[0033] When the plastic template hot pressing forming device is in the hot pressing process, when the motor 16 is started, it drives the cam 17 to rotate, and the cam 17 periodically contacts and pushes the second rotating shaft 13 downward during the rotation process. This action causes the second connecting rod 6 connected to the second rotating shaft 13 to move downward, and at the same time drives the first connecting rod 5 to move downward through the first rotating shaft 12;

[0034] The movement of the first connecting rod 5 and the second connecting rod 6 transmits force to the slider 8, causing the slider 8 to move downward along the slide rod 7 and compress the first spring 9. The downward movement of the slider 8 drives the hot pressing mechanism, enabling it to apply pressure to the plastic template placed thereunder to complete hot pressing molding.

[0035] When the plastic template hot pressing molding device is in overload protection, if the plastic template is too thick, the slider 8 cannot move further downward. In this case, the downward movement of the second connecting rod 6 is restricted, while the first connecting rod 5 can still continue to move downward.

[0036] Due to the connection between the first connecting rod 5 and the second connecting rod 6, the second rotating shaft 13 will continue to move downward, but the slider 8 remains stationary, so that the second spring 14 absorbs the excess force, achieving force balance through the second connecting rod 6 and the first spring 9, and protecting the motor 16 and the cam 17 from damage due to overload.

[0037] It should be noted that an L-shaped connecting member 18 is provided on the sliding block 8 , and a connecting plate 19 is provided on the L-shaped connecting member 18 .

[0038] Relevant staff can install the hot pressing mechanism on the connecting plate 19 according to actual conditions to facilitate fine adjustment of the position of the hot pressing mechanism.

[0039] It should be noted that the main mounting seat 1 is arranged on the fixing beam 20 , and the fixing beam 20 is arranged on the fixing plate 21 .

[0040] It should be noted that a shaft sleeve 22 is provided on the second rotating shaft 13 .

[0041] Providing the shaft sleeve 22 can reduce the friction between the second rotating shaft 13 and the shaft sleeve 22 and increase the service life.

[0042] It should be noted that both ends of the slide rod 7 are connected to the first mounting plate 2 via a fixing block 23 .

[0043] It should be noted that the first spring 9 is arranged below the slider 8 .

[0044] It should be noted that an oil filling port is provided on the fixing block 23 .

[0045] It should be noted that the angle α formed by the first connecting rod 5 and the second connecting rod 6 with the axis of the first rotating shaft 12 as a reference is less than 180 degrees.

[0046] Specifically, the angle α formed by the first connecting rod 5 and the second connecting rod 6 with the axis of the first rotating shaft 12 as the reference can be controlled between 120 degrees and 150 degrees, so that the first connecting rod 5, the second connecting rod 6 and the second spring 14 can be in a better initial linkage state, so that the device can achieve better overload protection performance.

[0047] In summary, the plastic template hot pressing forming device according to the embodiment of the utility model can allow the device to operate safely and effectively when encountering plastic templates of various thicknesses, thereby avoiding equipment failure caused by changes in the thickness of the plastic template.

[0048] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
