Abstract

The utility model discloses a closing mold depositing member for a mold guide pole and a mold guide sleeve, which comprises a nonmetallic columnar part and a nonmetallic guide pole matching part, wherein, the nonmetallic columnar part is in clearance fit with an inner hole of the mold guide sleeve; the nonmetallic guide pole matching part and the columnar part are formed integrally; the guide pole matching part is provided with the inner hole which is in clearance fit with the mold guide pole; the width between the top of the guide pole matching part and the columnar part is larger than the thickness of the wall of the guide sleeve; and the guide pole matching part includes an annular shoulder and a cylindrical part below the annular shoulder. The closing mold depositing member for the mold guide pole and the mold guide sleeve of the utility model adopts the structure, so that the matching precision between the closing mold depositing member for the mold guide pole and the mold guide sleeve and the mold guide pole and the guide sleeve is not high, and the precision for a travelling crane is not required to be very high. Therefore, the mold opening efficiency is greatly improved, the mold opening damage of the guide pole and the guide sleeve is avoided, and the production cost is reduced.

Description

Guide-post of die-set guide pin bushing matched moulds is deposited part

Technical field

The utility model relates to mould applications, relates in particular to a kind of guide-post of die-set guide pin bushing matched moulds and deposits part.

Background technology

Automobile making needs a lot of moulds, guide-localization between upper mould and the counterdie adopts the guide pillar guide pin bushing of precision-fit, at present adopt dual mode to come matched moulds to deposit usually during press under the mould, a kind ofly deposit naturally for allowing mould pattern tool deposit stop, another kind of for filling up with other hard article diagonal angle or four jiaos, which kind of situation no matter

The guide pillar guide pin bushing all must have darker wedging amount could guarantee the steady of mould, but not on press during die sinking, usually all be to open with driving, because of the quality of fit of guide pillar guide pin bushing very high, and driving is because of its intrinsic characteristics, four ropes are difficult to guarantee the equal length equal angles when lifting, even extreme care is slow, also be difficult to guarantee parallel axially from guide pin bushing, the extracting of guide pillar energy along the guide pillar guide pin bushing, thereby cause the crowded wound of guide pin bushing or the wound of spraining, cause guiding accuracy to descend, even guide pin bushing damages and scrap, production cost is higher.

The utility model content

Technical problem to be solved in the utility model is: provide a kind of guide-post of die-set guide pin bushing matched moulds to deposit part, can avoid the die sinking damage of guide pillar guide pin bushing when this kind guide-post of die-set guide pin bushing matched moulds is deposited the part use when driving promotes die sinking, reduce production costs.

Solve this technical problem, the technical solution of the utility model is: a kind of guide-post of die-set guide pin bushing matched moulds is deposited part, it is by forming with the nonmetal columnar portion of mold guide sleeve endoporus matched in clearance with the nonmetal guide pillar auxiliary section that columnar portion forms one, described guide pillar auxiliary section has the endoporus with the guide-post of die-set matched in clearance, and the width between top, described guide pillar auxiliary section and the columnar portion is greater than the wall thickness of guide pin bushing.

Described guide pillar auxiliary section is made up of the cylindrical portion of annulus shoulder and annulus shoulder below.

The annulus shoulder and the cylindrical portion of described guide pillar auxiliary section are step-like.

A kind of guide-post of die-set guide pin bushing of the utility model matched moulds is deposited part and is adopted such structure, before mould unloads from press, guide-post of die-set guide pin bushing matched moulds is deposited part place between guide-post of die-set, guide pin bushing, making does not have the wedging amount between guide pillar, guide pin bushing, can guarantee again simultaneously mould upper die and lower die steadily.The quality of fit of depositing part and guide-post of die-set, guide pin bushing because of guide-post of die-set guide pin bushing matched moulds is not high, so the driving precision is not had very high requirement, and mould is easy to be opened, so die sinking efficient promotes greatly, avoid the die sinking damage of guide pillar guide pin bushing simultaneously, reduced production cost.

Description of drawings

Below in conjunction with accompanying drawing a kind of guide-post of die-set guide pin bushing of the utility model matched moulds is deposited part and do explanation in further detail;

In Fig. 1, Fig. 2,1, columnar portion; 2, annulus shoulder; 3, cylindrical portion; 4, guide pin bushing; 5, patrix; 6, guide pillar guide pin bushing matched moulds is deposited part; 7, guide pillar; 8, counterdie.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of guide-post of die-set guide pin bushing matched moulds is deposited part 6, it is by forming with the nonmetal columnar portion 1 of the guide pin bushing 4 endoporus matched in clearance of patrix 5 with the nonmetal guide pillar auxiliary section that columnar portion 1 forms one, described guide pillar auxiliary section has the endoporus with guide pillar 7 matched in clearance of counterdie 8, width between top, described guide pillar auxiliary section and the columnar portion 1 is greater than the wall thickness of guide pin bushing 4, and the cylindrical portion 3 that 2 belows are takeed on by annulus shoulder 2 and annulus in described guide pillar auxiliary section is formed.The annulus shoulder 2 and the cylindrical portion 3 of described guide pillar auxiliary section can be for step-like.

Will be when lathe be unloaded down with mould, the cylindrical portion 3 of at first guide-post of die-set guide pin bushing matched moulds being deposited part 6 is placed on the guide pillar 7, make its dead in line as far as possible, do not have no relations even do not overlap yet, certain clearance is arranged because of the endoporus of cylindrical portion 3 and guide pillar 7 are monolateral, and there is a certain size chamfering guide pin bushing 4 porch, even contact the importing that also can not influence matched moulds instrument and guide pin bushing so the columnar portion that guide-post of die-set guide pin bushing matched moulds is deposited part 6 and guide pillar are monolateral, mould is descended, the annulus shoulder 2 of depositing part 6 until guide pin bushing 4 installed surfaces and guide pillar guide pin bushing matched moulds contacts, can dismantle this moment to lock between mould and lathe and tie up screw, after treating that the lathe slide block is up, the lathe table top is left and mould is hung lathe.

After using guide pillar guide pin bushing matched moulds to deposit part, when under press, using the driving die sinking, the guide pillar guide pin bushing high because of quality of fit do not have the wedging amount, guide pillar guide pin bushing matched moulds deposits part and the guide pillar guide pin bushing has enough fit clearances respectively, the required precision of the rope length, angle etc. of driving is reduced greatly, be enough to make and just can steadily open mould efficiently with driving a vehicle.

More than describe as can be seen, the use of when die sinking, depositing part owing to guide pillar guide pin bushing matched moulds, make the targeting part of upper and lower mould that certain clearance be arranged, so mould is easy to be opened, rod is pounded and with the puzzlement that jack pushes up, made things convenient for the work of on-the-spot pincers worker for die sinking employing wooden stick is prized, hung before having saved, and also can avoid the artificial die sinking damage of guide pillar guide pin bushing simultaneously, guarantee the quality of mould, reduced cost of manufacture.
