Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

example (b):

as shown in fig. 1-3, a tooling which is additionally arranged above a vulcanizing machine and is convenient for demolding comprises a demolding boss 1 and a driving mechanism 2 for driving the demolding boss 1 to do reciprocating linear motion along the vertical direction;

the demolding boss 1 is matched with a lower die 3 of a vulcanizing machine 11, the driving mechanism 2 is connected with the vulcanizing machine 11 through a connecting frame 4, the demolding boss 1 is connected with the driving mechanism 2, and the demolding boss 1 and a supporting plate 5 of the vulcanizing machine 11 are arranged in a vertically corresponding mode;

the demolding boss 1 is provided with a plurality of negative pressure suction nozzles 6, and the negative pressure suction nozzles 6 are connected with a negative pressure generating device 7 through air pipes.

The driving mechanism 2 is a cylinder.

Wherein the negative pressure suction nozzle 6 is arranged corresponding to the polytetrafluoroethylene film 14 formed in the lower die 3 up and down. The vulcanizer 11 is a prior art, and the detailed structure and principle thereof are not described herein. The negative pressure generating device 7 may be, but is not limited to, a vacuum pump.

The working principle is as follows: after the polytetrafluoroethylene film 14 is cooled and pressure-maintaining molded, the second cylinder 12 of the vulcanizer 11 pushes the second cooling plate 13 and the mold integrally onto the support plate 5, and at this time, the mold corresponds to the demolding boss 1 up and down. The upper die is manually taken down, the driving mechanism 2 is started, the driving mechanism 2 drives the demolding boss 1 to descend to be matched with the lower die 3, and at the moment, the negative pressure suction nozzle 6 is tightly attached to the polytetrafluoroethylene film 14.

And starting the negative pressure generating device 7, wherein the negative pressure generating device 7 enables the negative pressure suction nozzle 6 to generate negative pressure to firmly adsorb the polytetrafluoroethylene film 14, the driving mechanism 2 is started to reset to move upwards, and the polytetrafluoroethylene film 14 moves upwards synchronously. During the course of the polytetrafluoroethylene film 14 sheet going upwards, the second cylinder 12 of the vulcanizer 11 drives the second cooling plate 13 and the lower die 3 to return. After the driving mechanism 2 is reset, the negative pressure generating device 7 is switched off, and then the polytetrafluoroethylene membrane 14 sheet can be collected.

The utility model discloses an automatic drawing of patterns of 14 pieces of polytetrafluoroethylene membrane is realized in the negative pressure absorption, and the drawing of patterns is quick, convenient, and the drawing of patterns process need not artifical the participation, and mechanized quick drawing of patterns can effectively improve production efficiency, need not anxious drawing of patterns process scratch polytetrafluoroethylene membrane 14 pieces simultaneously.

Further, as shown in fig. 2, a plurality of the negative pressure suction nozzles 6 are uniformly arranged in a ring shape. The evenly arranged negative pressure suction nozzles 6 can ensure that the stress of the polytetrafluoroethylene film 14 in the demoulding process is even.

Further, as shown in fig. 3, three air blowing holes 8 are formed in the demolding boss 1, the air blowing holes 8 correspond to the side face of the molding cavity of the lower mold 3 and are uniformly distributed in an annular shape, and the air blowing holes 8 are connected with an air source 15 through air pipes. Wherein the air source 15 may be, but is not limited to, an air pump.

When the demoulding boss 1 is matched with the lower mould 3, firstly, air is blown to the side surface of the forming cavity of the lower mould 3 through the air source 15, air flow descends along the side surface of the forming cavity of the lower mould 3 and enters the lower surface of the polytetrafluoroethylene film 14 through a gap between the polytetrafluoroethylene film 14 and the side surface of the forming cavity, and preliminary loosening of the polytetrafluoroethylene film 14 is realized. Then the negative pressure generating device 7 is started to adsorb the polytetrafluoroethylene membrane 14 more easily and quickly.

Further, as shown in fig. 1, a blanking hole 9 with a size smaller than that of the lower die 3 is formed in the supporting plate 5, the blanking hole 9 corresponds to the demolding boss 1 up and down, and a material collecting box 10 is arranged below the blanking hole 9.

After the negative pressure generating device is disconnected, the polytetrafluoroethylene membrane falls freely under the action of gravity and enters the material collecting box through the material falling hole to realize automatic collection of the polytetrafluoroethylene membrane.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
