Abstract

The invention discloses an automatic molding press for tetrafluoro rings. The automatic molding press for tetrafluoro rings comprises a mold rack fixed to a column and a mold pressing barrel arrangedin the vertical central position of the mold rack, wherein the top of the mold pressing barrel drives an upper mold with a mold pressing bulge loop at the bottom through an upper oil cylinder to shrink up and down and the bottom inside drives a lower mold with a protruding shoulder to shrink up and down through a lower oil cylinder; the mold pressing bulge loop of the upper mold is arranged aligned to the protruding shoulder of the lower mold, and the top of the protruding shoulder of the lower mold, the inner side of the mold pressing barrel and the bottom of the mold pressing bulge loop encircle a sealed annular cavity; a poly tetrafluoroethylene material is obtained in the sealed annular cavity through a feeding pipe connected to a metering device of an injection molding machine; at least one unloading ejector rod penetrates through the protruding shoulder of the lower mold in the vertical direction, and the unloading ejector rods drive the lower mold to move up and down through anunloading power source; and the upper oil cylinder, the lower oil cylinder and the unloading power source are connected to a PLC control device. The automatic molding press achieves full-automatic processing of the tetrafluoro rings from loading to mold pressing forming and product unloading, and has the advantages of being high in processing efficiency, good in formed product quality and low in operating cost.

Description

technical field [0001] The invention relates to the technical field, in particular to an automatic molding machine for tetrafluoro sealing rings. Background technique [0002] High-molecular polymers, especially polytetrafluoroethylene (PTFE) and ultra-high molecular weight polyethylene (UHMWPE), due to their high melt viscosity, small friction coefficient, and low critical shear rate, bring great challenges to mixing and injection molding. It is very difficult to use existing injection molding machines for injection molding, and it is even more difficult to form oversized workpieces. [0003] Chinese patent, application (patent) number: CN03230670.9, has announced a kind of compound material, high molecular polymer special-purpose molding equipment, comprises the kneader (twin-screw or single-screw extruder) with batching hopper, with Injection barrels and molding machines for pistons. The outlet of the mixer is connected with the front outlet of the injection barrel thro...
