Abstract
The utility model discloses a mold ejecting structure of an automobile damping bracket. The mold ejecting structure comprises a lower mold plate of the mold and a base under the lower mold plate, wherein a limit through hole is formed in a lower mold plate cavity; a central shaft of the damping bracket is inserted into the limit through hole and located in the limit through hole; an ejection plate is arranged between the lower mold plate and the base; a plurality of ejection pillars are arranged on the ejection plate; each ejection pillar directly faces to the limit through hole of the lower mold plate; the ejection plate is clamped and fixed on the base; a cushion block used for supporting the lower mold plate is arranged on the base; an ejection hole is formed in the base; a vulcanizing machine cylinder piston rod penetrates through the ejection hole. According to the mold ejecting structure of the automobile damping bracket, the ejection plate is arranged between the base and the lower mold plate; when ejecting the mold, the cylinder of the vulcanizing machine ejects and lifts a middle mold, and the other cylinder penetrates through the base and ejects the central shaft of the product upwards; due to the adoption of a manner of pulling up and ejecting down, the central shaft can be ejected out of the mould from the limit through hole, so that the product deformation and the generation of waste product caused when the central shaft is difficulty ejected out of the mold can be avoided, thereby greatly increasing the qualification ratio of the product.
Description
Technical field
The utility model relates to part of automobile engine and manufactures field, is specifically related to a kind of automobile shock bracket mould mould unloading structure.
Background technology
automobile engine shock bracket is the important stressed member in automobile, is mainly automobile engine is risen and supported and cushioning effect.The structure of shock bracket is mainly by shell, central shaft and the yielding rubber being fixed between the two form, central shaft and engine support are connected, wherein yielding rubber is sulfidization molding in mould, existing mold comprises patrix, middle mould and counterdie, the cylinder of moulding after cure machine upwards ejects middle mould, product is followed its rising in middle model cavity, when product rises, the rubber section of sulfuration is subject to middle mould power upwards, because the central shaft bottom of product is inserted in counterdie and comparatively tight with counterdie laminating, central shaft is subject to counterdie downward " pulling ", rubber section and the central shaft of just moulding can become flexible, cause and be out of shape the generation that the even fracture of colloid causes waste product.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of automobile shock bracket mould mould unloading structure, and ejecting structure is set up in bottom, and product is ejected to counterdie from bottom, prevents the deformation and fracture of product, the generation of reducing the number of rejects and seconds.
The utility model is achieved through the following technical solutions:
Automobile shock bracket mould mould unloading structure, comprise lower bolster and the beneath base of lower bolster of mould, in lower bolster die cavity, be provided with the limiting through hole of inserting location for shock bracket central shaft, between described lower bolster and base, be provided with liftout plate, described liftout plate is provided with some fore-sets, described each fore-set faces the limiting through hole of described lower bolster, described liftout plate is fixed on described base, described base is provided with the cushion block that supports described lower bolster, offers the hole that ejects of passing through for vulcanizer cylinder piston rod on described base.
The further improvement project of the utility model is, leaves the gap of 2-5cm between the end face of described fore-set and the bottom surface of described lower bolster, and the diameter of described fore-set is slightly less than the aperture of described limiting through hole.
The utility model further improvement project is, described cushion block is fixed on described base, and the upper surface of described cushion block is provided with stopper slot, and the surrounding of described lower bolster bottom surface is provided with the spacing preiection coordinating with described stopper slot.
The utility model further improvement project is, described liftout plate bottom surface is provided with projection, and described base is provided with the groove engaging with described projection.
compared to the prior art the utility model has the following advantages:
The utility model is set up liftout plate between base and lower bolster, when when depanning, the cylinder of vulcanizer rises middle mould jack-up, another cylinder is through the upwards central shaft of top product of base, adopt the mode on " top of above leaving behind " to be convenient to central shaft depanning from limiting through hole, prevent from, because the more difficult depanning of central shaft causes the generation of deformation of products and waste product, greatly improving the qualification rate of product.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Automobile shock bracket mould mould unloading structure as shown in Figure 1, mould comprises that patrix 1, middle mould 2 and lower bolster 3 form, and is provided with base 4 under lower bolster 3, is provided with for shock bracket central shaft 5 and inserts the limiting through hole 51 of location in lower bolster 3 die cavities.Between lower bolster 3 and base 4, establish liftout plate 6, liftout plate 6 is provided with some fore-sets 61, each fore-set 61 faces the limiting through hole 51 of lower bolster 3, the top that central shaft 51 inserts the interior bottom of limiting through hole 51 and fore-set 61 offsets, liftout plate 6 is fixed on base 4, concrete, liftout plate 6 bottom surfaces are provided with projection 62, and base 4 is provided with the groove engaging with projection 62.Between the bottom surface of the end face of fore-set 61 and lower bolster 3, leave the gap of 2-5cm, the diameter of fore-set 61 is slightly less than the aperture of limiting through hole 51.
Still base 4 is provided with the cushion block 7 that supports lower bolster 3 as shown in Figure 1, and cushion block 7 is fixed on base 4, and the upper surface of cushion block 7 is provided with stopper slot, and the surrounding of lower bolster 3 bottom surfaces is provided with the spacing preiection 31 coordinating with stopper slot.On base 4, offer pass through for vulcanizer cylinder piston rod eject hole 41, when depanning, cylinder piston rod is through ejecting hole 41 jack-up liftout plates.
