Description
Technical field
The present invention relates to the part processing technique field of automobile exhaust gas recirculating system, particularly relate to the mould of a kind of automobile exhaust recirculation cooling system diffuser.
Background technology
Existing automobile bubbler before carrying out in road welding procedure, this big round mouth easily by high temperature deformation, and this bubbler follow-up assemble with cooling system time the circularity of this big round mouth is required higher, it is therefore desirable to this big round mouth is carried out full circle processing.In the past adding man-hour carrying out full circle, and be mostly that the outer wall being set in round mouth by shaping mould carried out simple full circle, its plastic precision is poor, is only applicable to less demanding to circularity and that round mouth is less full circle and processes.
Summary of the invention
For defect or deficiency present in prior art, the technical problem to be solved is: provide the mould of a kind of automobile exhaust recirculation cooling system diffuser, and it can guarantee that the required precision of big mouth full circle.
nullTo achieve these goals，The technical scheme that the present invention takes is for providing the mould of a kind of automobile exhaust recirculation cooling system diffuser，Including cover half die cavity mold insert、Pressing plate、Left cavity slide block、Slide guide pin、Solid plate、Dynamic model die cavity mold insert、Ball、Moving platen、Ball push rod、The big push rod in center、Support column、Right cavity slide block，Described cover half die cavity mold insert hanging platform is fixed in the fixing hole of described solid plate，Described dynamic model die cavity mold insert hanging platform is fixed in the fixing hole of described moving platen，A described left side、Right cavity slide block is arranged at a left side for described dynamic model die cavity mold insert、Right both sides are placed in the hole, location of described moving platen，A described left side、Before right cavity slide block inserts with slide guide pin respectively、In the slide guide hole of the wear-resisting slide plate on rear both sides，Described wear-resisting slide plate hanging platform is fixed in the fixing hole of moving platen，Described ball is arranged on the upper end of described ball push rod，The big push rod in described center is positioned at the centre of described two ball push rods，Described support column is positioned at the left side of described ball bar.
As a further improvement on the present invention, described ball push rod upper end is provided with ball grooves, and the size of described ball grooves is than two big 0.3-0.6mm of ball diameter sum.
The invention has the beneficial effects as follows: plastic precision is high, wherein workpiece locating piece carries out positioning from big round mouth outer wall, eight full circle slide blocks act ons by plug pushes as radial direction big round mouth internal face, thus completes the full circle to big round mouth wall and process.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mould of automobile exhaust recirculation cooling system diffuser of the present invention.
Wherein numeral represents: 1, cover half die cavity mold insert；2, pressing plate；3, left cavity slide block；4, slide guide pin；5, solid plate；6, dynamic model die cavity mold insert；7, ball；8, moving platen；9, ball push rod；10, the big push rod in center；11, support column；12, right cavity slide block.
Detailed description of the invention
The present invention is further described for explanation and detailed description of the invention below in conjunction with the accompanying drawings.
nullAs shown in Figure 1，The present invention provides the mould of a kind of automobile exhaust recirculation cooling system diffuser，Including cover half die cavity mold insert 1、Pressing plate 2、Left cavity slide block 3、Slide guide pin 4、Solid plate 5、Dynamic model die cavity mold insert 6、Ball 7、Moving platen 8、Ball push rod 9、The big push rod in center 10、Support column 11、Right cavity slide block 12，Described cover half die cavity mold insert 1 hanging platform is fixed in the fixing hole of described solid plate 5，Described dynamic model die cavity mold insert 6 hanging platform is fixed in the fixing hole of described moving platen 5，Described left cavity slide block 3、Right cavity slide block 12 is arranged at a left side for described dynamic model die cavity mold insert 6、Right both sides are placed in the hole, location of described moving platen 8，Described left cavity slide block 3、Before right cavity slide block 12 inserts with slide guide pin 4 respectively、In the slide guide hole of the wear-resisting slide plate on rear both sides，Described wear-resisting slide plate hanging platform is fixed in the fixing hole of moving platen，Described ball 7 is arranged on the upper end of described ball push rod 9，When die sinking is released，Left cavity slide block 3 and two slide guide pins of right cavity slide block 12 towel，Under thrust，Along front、Oblique guide runner in rear slide plate，While upward sliding，Synchronize to two side shiftings，Thus detach plastic，Complete the demoulding.Left cavity slide block 3 and right cavity slide block 12 synchronize when two side shiftings, and form the rolling friction of point cantact between ball, because its friction area is minimum, so, its frictional resistance is the most minimum, when not only making side core-pulling very flexible, and abrasion between the two is the most minimum, effectively extend the two easily grind, the life-span of quick-wear part；The big push rod in described center 10 is positioned at the centre of described two ball push rods, and described support column 11 is positioned at the left side of described ball bar 9.
As it is shown in figure 1, described ball push rod 10 upper end is provided with ball grooves, the size of described ball grooves is than two big 0.3-0.6mm of ball diameter sum.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
