Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description is made to the preferred embodiment of air filter pipe manufacturing method of the present invention:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, air filter pipe manufacturing method comprises the following steps:
A) mould is made:
Air filter pipe 2 mould mainly comprises external mold and internal mold, and external mold is in order to the outer wall of shaping air filter pipe 2, and internal mold is in order to shaped inner.
External mold comprises body mould, mouth of pipe fixed die 3 and cinclides mould 4.Body mould is not shown, in order to the exposed part of shaping Fig. 1 hollow chimney filter 2.Mouth of pipe fixed die 3 forms by two pieces, while the mouth of pipe outer wall in order to shaping air filter pipe 2, is also used for fixing the mouth of pipe of air filter pipe 2, so that the core_pulling demoulding of tube head internal mold 7.Cinclides mould 4 is in order to the hole on shaping air filter pipe 2 tube wall, and cinclides mould 4 and mouth of pipe fixed die 3 fit together, together the whole mouth of pipe outer wall of shaping air filter pipe 2.
Internal mold comprises tube head internal mold 7 and mouth of pipe internal mold 8, so-called tube head, refers to that air filter pipe 2 the first half has the part of ripple fold; The so-called mouth of pipe, refers to that air filter pipe 2 the latter half has uncovered part.Tube head internal mold 7 is in order to the inwall of shaping air filter pipe 2 tube head part, and mouth of pipe internal mold 8 is in order to the inwall of shaping air filter pipe 2 opening part.The left end of tube head internal mold 7 and the upper end closed butt joint of mouth of pipe internal mold 8, form interface surface 5, interface surface 5 is positioned at tube head and the mouth of pipe junction of air filter pipe 2, is also pipe shaft corner.From Fig. 2 profile, interface surface 5 extends through lower edge from the upper edge of pipe shaft corner.
Interface surface 5 is combined by several sections of curved surfaces and plane, comprising a guide surface 51, the tangent plane of air filter pipe 2 inwall and contact position, interface surface 5 lower end parallels with guide surface 51, thus in order to limit direction when tube head internal mold 7 core_pulling demoulding starts, when preventing the lower-left end of tube head internal mold 7 from loosing core, scratch air filter pipe 2 inwall.Interface surface 5 lower end 52 of tube head internal mold 7 smoothly transits with the lower surface of tube head internal mold 7, adopts mode boundary line being polished into fillet to reach smooth excessive object, further enhances the protection of the process of loosing core to air filter pipe 2 inwall.
Tube head internal mold 7 is fixedly mounted on core-pulling slide block 1, and slide rail 11 direction of core-pulling slide block 1 is consistent with the axis direction of air filter pipe 2 pipe shaft corner, smooth and easy with what ensure to loose core.The right-hand member outer wall of tube head internal mold 7 arranges ripple 71, in order to the ripple fold of shaping air filter pipe 2 inwall.Tube head internal mold 7 inside arranges water-cooling system 72, the water cooled pipeline that water-cooling system 72 passes in and out for single channel, and the inlet segment of water cooled pipeline and water exit end form interval spiral winding shape.Water-cooling system 72, in order to reduce rapidly the temperature of air filter pipe 2, makes its fast cooling shaping, improves injection mo(u)lding efficiency and yield rate.
Mouth of pipe internal mold 8 is fixedly mounted on and ejects on seat 6, substantially in vertical cylindrical.Eject seat 6 inside and arrange air blowing pipeline 61, air blowing pipeline 61 extends in mouth of pipe internal mold 8 always vertically upward, and its outlet is positioned at interface surface 5.Eject seat 6 inside and be also provided with push rod 62 straight up, withstand the uncovered inwall of air filter pipe 2 mouth of pipe, in order to ejection device.
B) injection mo(u)lding:
After through step, a) Mold Making installs, injection moulding in mould, passes into cold water to water-cooling system 72, makes air filter pipe 2 cooling forming.
C) demoulding:
1. body moulding/demoulding: adopt conventional slide block to skid off body mould;
2. tube head internal mold 7 demoulding: blow to air blowing pipeline 61, tube head internal mold 7 and air filter pipe 2 inwall are departed from, and water-cooling system 72 is intake and is cooled, and core-pulling slide block 1 outwards extracts tube head internal mold 7 out simultaneously, completes tube head internal mold 7 demoulding;
3. cinclides mould 4 core_pulling demoulding: the first slide block of cinclides mould 4 skids off, after treating that cinclides mould 4 slide block skids off the demoulding, hollow mold 41 is loosed core and has been taken off by force the demoulding of whole cinclides mould 4;
4. mouth of pipe fixed die 3 slide block skids off the demoulding;
5. mouth of pipe internal mold 8 demoulding: push rod 62 ejects air filter pipe 2, makes itself and mouth of pipe internal mold 8 depart from, thus completes the manufacture of whole air filter pipe 2.
