Description
Technical field
The utility model is relevant for a kind of Metal-magnetic needle of plastic tube, espespecially a kind ofly utilizes the magnetic induction heating, effectively to enhance productivity, and reaches the Metal-magnetic needle of the plastic tube of the benefits such as carbon reduction.
Background technology
The processing procedure of plastic molding press is mainly the raw materials such as solid plastic to be put into to the material pipe of forming machine, relend by heating material pipe, make solid material in the material pipe be molten into flow-like, the screw rod rotation continued in being installed in the material pipe is exerted pressure, with the raw material that will be fluid, inject among mould, this fluid material can be cured as finished product in die cavity.
And the material pipe heating device of existing plastic molding press forms by being coated on the electric heating piece of expecting the pipe periphery wall mostly, see through the electric heating piece be coated on outside the material pipe and generate heat to heat the material pipe, will expect solid material heating and melting in pipe.Yet this has now and heats the material Manifold technology with electric heating piece, but finds that there is on the implementation following many defects:
1. this electric heating piece all can generate heat due to inside and outside, inboard heat energy can conduct to the material pipe, outside heat energy can scatter and disappear in air, so the heat that electric heating piece produces only has half to be expected that pipe absorbs, so, except causing energy loss and waste, in the heat conduction, a large amount of loss heat energy, can diverge in context, makes the dealer must install air-conditioning additional and reduce the factory building temperature, further cause power consumption, the utmost point does not meet the environmental protection trend of modern carbon reduction.
2. the mode of heating of this electric heating piece is owing to seeing through heating material pipe, again to heating raw materials in the material pipe, therefore raw material is subject to thermal velocity slower, relatively cause production efficiency to reduce, and this is coated on the electric heating piece of material pipe and expects that gap or pad place formation focus between pipe more can cause the estrangement of heat conduction, and make the interior raw material efficiency of electric heating piece heating material pipe more slow, and the heating of electric heating piece internal resistance wire is because power density is low, therefore, for the needs higher temperature, just fusible raw material is inapplicable, and can't provide various raw material plastic shapings required, more cause and use upper not convenient property.
3. this electric heating piece is by this material pipe of thermal contact conductance, so that heat energy is by outer past interior conduction feeding pipe, therefore material pipe temperature outside is higher than inboard temperature, for putting forward the inboard enough melt temperatures of feeder sleeve, therefore, electric heating piece must be increased to suitable high temperature, if accidentally just easily occur, scald unexpected, and electric heating piece is easy Yin Gaowen and produce aging fracture situation also, therefore use upper must the maintenance continually, causes the maintenance cost raising.
So, the inventor is because the electric heating piece heater of existing plastic tube has above-mentioned many familiar lacunas, so borrow it for many years in the manufacture of association area and assisting a ruler in governing a country of design experiences and knowledge, and through clever thought in many ways, heater for existing plastic tube is researched and developed improvement, and grind, creates the utility model.
