Problems solved by technology

[0004] The invention provides an all-in-one machine for wire winding and demoulding of electric fusion pipe fittings, which has the beneficial effect of fast demoulding and good injection molding quality, and solves the problem of the all-in-one machine for wire winding and demoulding of electric fusion pipe fittings mentioned in the above background technology. When melting pipe fittings, it is necessary to take out the mandrel, but at this time the internal temperature of the electrofusion pipe is relatively high, and it has not yet been solidified and formed. The fusion pipe fittings are strained, and even cause the deformation of the initially solidified electrofusion pipe fittings

Abstract

The invention relates to the technical field of electric melting pipe fitting machining, and discloses an electric melting pipe fitting wire winding and demolding all-in-one machine which comprises a shell and a mold in the shell, a machining device is slidably connected to the interior of the mold and used for assisting the mold in injection molding of an electric melting pipe fitting, and the machining device comprises a supporting column abutting against the inner wall of the mold; a round pipe is installed on the supporting column, a copper coil is wound on the round pipe, and a clamping component is further installed on the round pipe and used for clamping the copper coil. The inner wall of the electric melting pipe fitting can be rotationally flattened through rotation of the round pipe, the interior of the electric melting pipe fitting is bright, high-temperature gas in the electric melting pipe fitting rotates along with rotation stirring of the round pipe, the air temperature in the mold is fused, then the inner cooling speed of the electric melting pipe fitting is roughly the same, the injection molding efficiency is improved, and the production cost is reduced. And subsequent lifting of the connecting disc, the connecting pipe, the circular pipe and the supporting column is facilitated.

Description

technical field [0001] The invention relates to the technical field of electrofusion pipe fittings processing, in particular to an integrated machine for wire winding and demoulding of electrofusion pipe fittings. Background technique [0002] Electrofusion pipe fittings refer to a kind of plastic pipe fittings that can be melted and connected by the temperature generated by the current. The capacity is the main parameter. In some low-voltage circuits, the voltage requirements are not high, and only the number of amps can be marked. The pipe fitting is made by winding the resistance wire onto the mandrel first, and then molding the pipe fitting by injection molding around the coil and the mandrel, making sure to put the mandrel around the wire into the injection molding machine and remove the pipe fitting from the injection molding machine, After that, before removing the mandrel from the injection molded tube. [0003] However, when the existing electrofusion pipe fittings...
