Abstract
The invention provides a two-side inclined iron core pulling structure for an oil pan cavity. The two-side inclined iron core pulling structure comprises a lower die body, an upper died body and an upper support plate. A side module is arranged in the lower die body, and the upper support plate is arranged above and connected with the upper die body through connection columns. The structure is characterized by further comprising inclined pulling cores. One ends of the inclined pulling cores stretch into the lower die body to be matched with the side module, the other ends penetrate through the upper die body to stretch into guide holes in the upper support plate, and the inclined pulling cores are in sliding fit with inclined holes in the upper die body.
Description
Technical field:
The present invention relates to casting mould technical field, relate in particular to that a kind of oil sump inner chamber is two-sided tiltedly takes out core structure.
Background technology:
For the hollow-core construction in some heavy castings, be generally the casting being realized hollow-core construction by core procedure in casting process.But this mode is the defect such as ubiquity location difficulty in actual mechanical process, especially to the structure larger with some volumes, core is inherently very large, just more difficult in die cavity inner position, and, the gas forming amount in casting process of large-scale core is large, and heat radiation is slow, easily causes foundry goods gas shrinkage defect, in addition, core can not be recycled, and relative cost strengthens, and core is got angry when pouring into a mould and caused workshop condition seriously polluted.
Summary of the invention:
For solving above-mentioned technical problem, the invention provides and a kind ofly be conducive to reducing costs, enhance productivity and be conducive to improving that the oil sump inner chamber of production environment is two-sided tiltedly takes out core structure.
Technical scheme of the present invention is, there is provided that a kind of oil sump inner chamber with following structure is two-sided tiltedly takes out core structure, lower mold body, upper die body and upper plate, in lower mold body, be provided with side form block, upper plate is positioned at the top of upper die body and is connected by joint pin, it is characterized in that: it also comprises tiltedly looses core; The one end of tiltedly loosing core reaches in lower mold body and coordinates with side form block, and the other end reaches in the pilot hole on upper plate through upper die body, tiltedly looses core and the inclined hole sliding fit on upper die body.
After adopting said structure, the present invention has following remarkable advantage and beneficial effect:
First do not need to use core, pollution can be effectively reduced, production environment is improved, and secondly, tiltedly looses core and can repeatedly use, be conducive to reducing costs, by the acting in conjunction of inclined hole and pilot hole, ensure the action full automation of tiltedly loosing core, whole operation more specification, also simple, be conducive to the steady quality ensureing product.
Accompanying drawing illustrates:
To be that oil sump inner chamber of the present invention is two-sided tiltedly take out core structure to Fig. 1.
Detailed description of the invention:
Below in conjunction with drawings and the specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of oil sump inner chamber of the present invention is two-sided tiltedly takes out core structure, and lower mold body 1, upper die body 2 and upper plate 3, be provided with side form block 4 in lower mold body 1, upper plate 3 is positioned at the top of upper die body 2 and is connected by joint pin 5.
It also comprises tiltedly looses core 6, and described tiltedly loosing core 6 is two pieces.
Tiltedly loose core 6 lower end reach in lower mold body 1 and coordinate with side form block 4, the upper end of tiltedly loosing core reaches in the pilot hole 7 on upper plate 3 through upper die body 2, inclined hole 8 sliding fit of tiltedly loosing core on 6 and upper die body 2.Rely on the inclined hole 8 on upper die body 2 to tiltedly loose core 6 position play guiding and driving effect, for die sinking, first, upper die body 2 and upper plate 3 move, tiltedly loose core 6 not on move, but move horizontally under the effect of inclined hole 8, depart from side form block 4, tiltedly loose core 6 the pilot hole 7 of upper end on upper plate 3 traversing, when tiltedly loosing core 6 with after side form block 4 departs from completely, tiltedly loose core 6 upper end move to the other end of pilot hole 7 on upper plate 3 and offset always, like this, 6 to mention tiltedly loosing core under the acting in conjunction of upper die body 2 and upper plate 3.
