However, since the mold 41 and the mold flange 63 are integrally formed, both the mold 41 and the mold flange 63 must be replaced, thereby making the mold manufacturing cost very large.
[0075] In addition, even if it is not necessary to form the space portion 46 in the core 42, a large amount of mold manufacturing costs will be incurred due to the formation of the space portion 46.

Abstract
The present invention provides a PE-X pipe forming device, which includes a feeder for supplying solid material uniformly; a compressor for compressing solid material and supplying it to a forming piece uniformly; a heater for heating solid material to a fluid material to form a PE-X pipe; a forming piece for making the heater change into fluid material to form PE-X pipe; a protruding edge for connecting the compressor with the forming piece. it does not use the oil heater, oil cycle pump and oil tank of the heater, but prolongs the module core of the forming piece and the length of the die, a heater is set in the exterior surface of the die, the protruding edge of the die and the connector of the die, the insulating material is set for heating insulation for the first heater of the exterior surface of the die, the second heater of the protruding edge and the third heater of the connector. The apparatus can reduce the cost, and improve the productivity, prevent forming quality problems, improve the working circumstance and prevent safety accidents.
Description
technical field [0001] The present invention relates to a cross-linked polyethylene (PE-X) pipe forming device, and more particularly to such a PE-X pipe forming device which, by extending the length of the mold and core of the formed part, Heaters are arranged on the outer periphery of the extended mould, its flange portion and its adapter, and an insulating material is arranged to heat the first heater arranged on the outer peripheral surface of the mould, and the second heater arranged on the flange portion. Insulation of the heater and the third heater arranged on the adapter piece can reduce the power consumption for the oil heating device and the oil circulation pump, and the cost of oil can be reduced because consumable oil is not used, and especially by The mold cost is reduced by separating a mold for a formed part attached to a flange portion from the flange portion and mounting the mold on the flange portion. Background technique [0002] Generally, a PE-X pipe i...
