The invention relates to a molding machine for polytetrafluoroethylene rods, in particular to a polytetrafluoroethylene molding pushing press convenient for replacing a mold core. The body of the pushing press comprises a mold core rod, an upper mold core rod press plate, a bottom plate seat, a mold core rod positioning plate and a heating sleeve, wherein the mold core rod positioning plate and the heating sleeve are connected into a whole through a long bolt and provided with mutually communicated first mounting holes; the upper mold core rod press plate is arranged below a batching disk, and a connecting port is arranged on the batching disk; the upper part of the upper mold core rod press plate is arranged in the connecting port, and a second mounting hole is arranged on the upper moldcore rod press plate; a mold hole is arranged on the mold core rod, and the outer ring of the mold core rod is provided with a positioning convex ring; the mold core rod on the lower part of the positioning convex ring is arranged in the first mounting holes, and the mold core rod on the upper part of the positioning convex ring is arranged in the second mounting hole; and the mold hole is communicated with the batching disk and just aims to a pushing and pressing core rod on a pushing and pressing device. The invention has the characteristics of simple structure and convenient implementation.
Description
technical field [0001] The invention relates to a molding machine for polytetrafluoroethylene rods. Background technique [0002] PTFE plastic is an engineering plastic with excellent performance. It has good self-lubricating performance, low friction coefficient, high and low temperature resistance, corrosion resistance, good insulation performance and non-stickiness. It is widely used in machinery, electronics, petroleum, Chemical, food, light industry and other industries. [0003] Existing polytetrafluoroethylene plastic rods are generally prepared by hot extrusion. Existing rod hot pressing extruders are mainly horizontal. Such as figure 1 As shown, the extruder consists of the following parts: hydraulic system 1, oil cylinder 2, hopper 6, body 8, ejector rod 3, etc. The shortcomings of this horizontal machine structure mainly include the following aspects: (1), the output is low, and only one bar can be rolled out at a time, and the speed is too slow to meet the cu...
