[0015] The technical scheme in the embodiment of the utility model will be described clearly and completely, obviously, the described embodiment only is a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of the utility model protection.

[0016] Please refer to Figs. 1-3This utility model discloses a high-pressure vacuum rapid mold opening and forming mechanism, comprising: a column 1, an upper lifting template 2, a base 3, an upper seat 4 mounted on the column, a vacuum hood 5, an auxiliary hydraulic cylinder 6 mounted on the base, a middle seat 7 connected to the output end of the auxiliary hydraulic cylinder, and an inlet / outlet template 8 slidably mounted on the middle seat. The upper end of the upper lifting template is hinged to the vacuum hood, and the lower end of the upper lifting template is connected to the inlet / outlet template via a flipping assembly. The flipping assembly includes a shaft fixing seat 9 mounted on the inlet / outlet template, a positioning pin 10 mounted on the shaft fixing seat, and a first exhaust spring 11 sleeved on the positioning pin. The upper end of the positioning pin is hinged to the lower end of the upper lifting template. At this time, the vacuum hood, the upper lifting template, and the inlet / outlet template form a Z-shaped linkage structure. The inlet / outlet template has two sides... The sliding groove 12 of the middle seat is provided with several rollers 13 to facilitate the reciprocating movement of the entry and exit template. During operation, the auxiliary oil cylinder extends and drives the upper middle seat to move upward, thereby driving the entry and exit template on the middle seat to move upward. The entry and exit template is hinged to the lower end of the upper lifting template. The upper heating plate on the vacuum cover is hinged to the upper end of the upper lifting template and is fixed at this time. Under the lifting drive of the auxiliary oil cylinder, the entry and exit template moves horizontally backward along several rollers to facilitate alignment with the upper and lower parts of the vacuum cover. At the same time as the auxiliary oil cylinder closes the mold, it pushes the entry and exit template backward to close the mold. The mold opening operation principle is the same, which will not be described in detail here. It can save a step of action, saving time and cost. It does not require the oil cylinder to push out the template and mold, making the operation convenient and quick, and enabling rapid mold opening and closing operations.

[0017] Specifically, the inlet and outlet template is provided with a lower vacuum sealing frame 14 that cooperates with the vacuum hood, and a heating plate 15 is provided on the inlet and outlet template. When the mold is closed, the lower vacuum sealing frame cooperates with the vacuum hood to form a mold processing cavity. Several second exhaust springs 16 are provided at intervals on the inner side of the lower vacuum sealing frame to apply an upward force to the upper lifting template. When the mold is opened, they assist the upper lifting template to complete the mold opening operation more quickly.

[0018] Specifically, it also includes a vacuum cover guide post 17, the upper end of which is connected to the upper seat, and the lower end of which is connected to the vacuum cover, serving a guiding function.

[0019] The beneficial effects of this utility model are: this mechanism does not require the hydraulic cylinder to push out the template and mold. The upper end of the upper lifting template is locked on the upper heating plate of the vacuum hood, and the lower end is locked on the inlet and outlet template through connecting parts such as the pin mounting seat. The mold is opened when the inlet and outlet template is pushed forward by the auxiliary hydraulic cylinder to open the mold. This can save a step, save time and cost, shorten the production cycle, and improve work efficiency, thus bringing great convenience to production and use.

[0020] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, are all included in the patent protection scope of the present application.
