Abstract
The invention relates to a bearing-less PP (polypropylene)/PE (polyethylene) high-temperature rotating net die and a rotating method. The bearing-less PP /PE high-temperature rotating net die can realize radial positioning of an internal die rotating body and positioning of an upper external die rotating body and a lower external die rotating body, and can substitute a high-temperature bearing by a copper sleeve under high temperature condition. The bearing-less PP /PE high-temperature rotating net die comprises a PP/ PE high-temperature rotating net die, wherein the copper sleeve is sleeved between an internal die and an external die in the PP/ PE high-temperature rotating net die. The invention has the advantages that: (1) the internal die and the external die adopt the copper sleeve to realize the radial positioning, the self expansion rate of the copper sleeve reaches the fitting clearance requirement of an internal die core and an external die core to ensure the molding requirement of an internal rotating die and an external rotating die under the influence of high temperature, moreover, the friction coefficient is small, the cost is low, and the technical effect which the high-temperature bearing cannot obtain is achieved; (2) since the copper sleeve is adopted for radial positioning, the dependence of the internal die and the external die on high-temperature grease can be avoided during continuous rotation under high temperature (100-280 DEG C) condition, thereby ensuring that the product surface is cleaner, greatly improving the die continuous operation and reducing the labor intensity.
Description
Technical field
The present invention relates to a kind of under the condition of high temperature, can either realize the radial location of internal mold rotary body, can realize again external mold rotary body location up and down, simultaneously again can enough copper sheathings replace no bearing PP, PE high temperature rotation net mould and the spinning solution of high-temperature bearing, belong to the high temperature rotating mould and make the field.
Background technology
At present, the PP that sells on the market, PE high temperature rotation net mould, between the internal mold and external mold on structural design in its high temperature rotation net mould, internal mold and outside intermode put and all adopt the high-temperature bearing radial location.Its weak point: the one, because the heat-resisting quantity of high-temperature bearing is subjected to the influence of its environment temperature big, under the hot environment temperature, the heat resistance of its high-temperature bearing reduces greatly, and wearing and tearing strengthen, and service life is short; The 2nd, to lubricious grease requirement, not only must use high-temperature grease, and the polluted product surface; The 3rd, continuous poor performance, cost height.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of under the condition of high temperature, can either realize the radial location of internal mold rotary body, can realize again external mold rotary body location up and down, simultaneously again can enough copper sheathings replace no bearing PP, PE high temperature rotation net mould and the spinning solution of high-temperature bearing.
Design: in order to realize above-mentioned purpose of design.Be equipped with copper sheathing between internal mold in PP, the PE high temperature rotation net mould and the external mold, internal mold is put the design of overlapping copper sheathing with outer intermode, is major technique feature of the present invention.The purpose of doing like this is: because interior external mold stamen rotates under high temperature (100-280) condition, adopt the not only high temperature resistant energy of bearing radial location poor, and since bearing in steel ball under the hot operation state, its wear extent is big, cause the bearing clearance to increase, do not reach the purpose of high accuracy radial location; And the application adopts copper sheathing to get high-temperature bearing, it is under the state of hot operation, be subjected to the influence of high-temperature temperature, the system of its thermal expansion makes just between copper sheathing and the inside and outside die body and forms precision-fit, not only can reach the high accuracy radial location, and long service life, and do not have high-temperature grease and can not produce and pollute product surface.
Technical scheme 1: no bearing PP, PE high temperature rotation net mould, it comprises PP, PE high temperature rotation net mould, is equipped with copper sheathing between internal mold in described PP, the PE high temperature rotation net mould and the external mold, internal mold is put the cover copper sheathing with outer intermode.
Technical scheme 2: no bearing PP, external mold stamen spinning solution in the PE high temperature rotation net mould, reductor drives rotary body on the external mold with power transmission to external mold rotating sprocket and external mold rotating sprocket, rotary body just changes under the external mold, its copper sheathing reaches turns to the external mold backspin, radial location with the external mold rotary body, counter-rotating of internal mold rotating sprocket and the rotation of drive internal mold rotary body, its copper sheathing reaches the radial location to the internal mold rotary body, the internal mold rotary body drives internal orifice mould fixed body, the rotation of internal orifice mould, rotary body on the external mold, rotary body drives external mold fixed body and the rotation of collar extension mould respectively under the external mold.
The present invention compares with background technology, the one, interior outer mold adopts the copper sheathing radial location, external mold stamen rotates under high temperature (100-280) condition in it, the fit clearance (0.01-0.15MM) of external mold stamen required, guarantees the moulding requirement of inside and outside rotating die in the heat rate of rising of copper sheathing self reached, its copper sheathing use under high temperature (100-280) condition, coefficient of friction is little, at the bottom of the cost, obtain the technique effect that can't obtain in than high-temperature bearing; The 2nd, adopt the copper sheathing radial location, solved interior external mold stamen under high temperature (100-280) condition continuously rotation to the dependence of high-temperature grease, product surface is more cleaned, the mold work continuity is strengthened greatly, labor strength reduces greatly.
