Description
Technical field
The present invention relates to a kind of mould of auto parts and components, particularly relate to the air filter pipe mold being easy to the demoulding.
Background technology
Air filter pipe is the important spare part of automobile engine, as engine intake passage.Mainly comprise tube head and mouth of pipe two parts, the pipeline of the two formation distortion that is docking together.Due to its out-of-shape, common manufacture method is tube head and mouth of pipe injection mo(u)lding respectively, then tube head and the mouth of pipe is stitched together, thus makes an air filter pipe.Such manufacturing technology steps is numerous and diverse, and because the existence of splicing process, causes the shape of final finished to be difficult to reach requirement, cause defect rate high.
Summary of the invention
The invention provides a kind of can the air filter pipe mold being easy to the demoulding of one-body molded air filter pipe.In order to realize foregoing invention object, present invention employs following technological means:
Be easy to the air filter pipe mold of the demoulding, comprise internal mold and external mold; Described external mold comprises body mould, mouth of pipe fixed die and cinclides mould, the outer wall of three's combination forming air filter pipe; Described internal mold comprises mouth of pipe internal mold and tube head internal mold, the inwall of the two combination forming air filter pipe; Described mouth of pipe internal mold and tube head internal mold butt up against interface surface; Described interface surface is sphere, the interface surface evagination of described tube head internal mold; Described mouth of pipe internal mold inside arranges air blowing pipeline; The outlet of described air blowing pipeline is positioned at interface surface.
Described tube head internal mold is fixed on core-pulling slide block;
Described interface surface is positioned at air filter pipe pipe shaft corner;
Described tube head internal mold inside arranges water-cooling system.
Beneficial effect of the present invention is: the mode of the internal mold employing mouth of pipe internal mold that air filter inside pipe wall is shaping and the docking of tube head internal mold combines, add the stripping means of blowing and loosing core and combining, make air filter pipe can be one-body molded, interface surface is that sphere is beneficial to and blows afloat uniform stream and enter air filter pipe, can not scratch air filter inside pipe wall while being beneficial to the even demoulding; Interface surface is positioned at air filter pipe pipe shaft corner, is beneficial to the core_pulling demoulding of tube head internal mold; Water-cooling system contributes to fast cooling shaping air filter pipe, accelerates injection mo(u)lding speed.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention is easy to the air filter pipe mold of the demoulding;
Fig. 2 is the sectional view of Fig. 1;
Fig. 3 is the demoulding schematic diagram of tube head internal mold 7.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment the present invention being easy to the air filter pipe mold of the demoulding makes detailed description:
As shown in Figure 1, Figure 2 and Figure 3, the air filter pipe mold being easy to the demoulding 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 the part of worn-out mouth.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 spheres, sphere centre is perpendicular to the central axis of air filter pipe 2.The upper end of interface surface 5 is positioned at the center of air filter pipe 2 corner, and lower end is positioned at the tip position of opening part cylinder shape inner wall.Interface surface 5 sphere of tube head internal mold 7 protrudes left, lower end 52 smoothly transits with the lower surface of tube head internal mold 7, mode boundary line being polished into fillet is adopted to reach smooth excessive object, the interface surface 5 of spherical shape and the lower end 52 of smooth interface surface 5, scratch air filter pipe 2 inwall when can effectively prevent the lower-left end of tube head internal mold 7 from loosing core.
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 worn-out mouth inwall of air filter pipe 2 mouth of pipe, in order to ejection device.
When manufacturing air filter pipe 2, body mould, mouth of pipe fixed die 3 and cinclides mould 4 are combined into external mold, and tube head internal mold 7 and mouth of pipe internal mold 8 are combined into internal mold, and internal mold and external mold are together to form the die cavity of air filter pipe 2, then to injection moulding in die cavity.After cooling forming, first, the first demoulding of body mould; Secondly, blow to air blowing pipeline 61, tube head internal mold 7 and air filter pipe 2 inwall are departed from, because interface surface 5 is spheric, the surrounding entering air filter pipe 2 inwall of uniform stream during air blowing, and then ensure the uniform break away from moulds of air filter pipe 2 inwall, water-cooling system 72 is intake and is cooled, core-pulling slide block 1 outwards extracts tube head internal mold 7 out simultaneously, completes tube head internal mold 7 demoulding; 3rd, cinclides mould 4 is loosed core and is taken off the demoulding by force; 4th, mouth of pipe fixed die 3 slide block skids off the demoulding; Finally, push rod 62 ejects air filter pipe 2, completes whole demoulding, and air filter pipe 2 has manufactured.
