Abstract
A pressure thermoforming machine comprises a lower bracket having a molding half moveably supported thereon. An upper bracket is securely connected to the lower bracket. An upper molding half is moveably supported thereon. Driving blocks are moveably and oppositely mounted on the lower bracket. Each driving block includes an inclined surface and the driving blocks are moveably interconnected such that the driving blocks move toward and away from each other simultaneously. Rollers are mounted on the lower molding half with respect to the inclined surface of the driving block such that the lower molding half moves upward when the driving blocks move toward each other, and lower downward when the driving blocks move away from each other.
Claims5
A pressure thermoforming machine, comprising:
- a lower bracket;
- a lower molding half moveably supported on the lower bracket;
- an upper bracket securely connected to the lower bracket;
- an upper molding half moveably supported by said upper bracket;
- and
- supporting means arranged between the lower molding half and the lower bracket, and including first and second driving blocks, each said driving block having at least a first and a second inclined surface, with an angle of inclination of the first surface being different from an angle of inclination of the second surface, the first and second inclined surfaces of the first driving block being disposed to face the first and second inclined surfaces of the second driving block, the first and second driving blocks being relatively movable toward and away from each other, the lower molding half being supported by the inclined surfaces of said driving blocks to prevent any unbalancing during a molding process, and so that the lower molding half moves upward when the driving blocks move toward each other, and moves downward when the driving blocks move away from each other;
- and wherein the lower molding half moves upward and downward more quickly when it is disposed on the first inclined surfaces than when it is disposed on the second inclined surfaces.
A pressure thermoforming machine, comprising:
- a lower bracket;
- a lower molding half moveably supported on the lower bracket;
- an upper bracket connected to the lower bracket;
- an upper molding half moveably supported by the upper bracket;
- and
- supporting means arranged between the lower molding half and the lower bracket, and including a pair of oppositely disposed driving blocks on the lower bracket, the driving blocks being moveably connected to move simultaneously toward and away from each other, the lower molding half being supported by the driving blocks to prevent any unbalancing during a molding process,
- wherein the driving blocks are connected by a rack and gear to move simultaneously to push the lower molding half upward when the driving blocks move toward each and lower the lower molding half down when the driving blocks move away from each other.
A pressure thermoforming machine, comprising:
- a lower bracket;
- a lower molding half moveably supported on the lower bracket;
- an upper bracket connected to the lower bracket;
- an upper molding half moveably supported by the upper bracket;
- driving blocks moveably and oppositely mounted on the lower bracket, each driving block including an inclined surface, the driving blocks being moveably interconnected such that the driving blocks move toward and away from each other simultaneously;
- and
- rollers mounted on the lower molding half and supported by the inclined surfaces of the driving blocks such that the lower molding half moves upward when the driving blocks move toward each other, and moves downward when the driving blocks move away from each other;
- wherein the driving blocks are interconnected by racks and gears such that the driving blocks move simultaneously.
