Abstract
The utility model provides a venting plug for a foundry technique. The venting plug is installed at the upper end of a venting hole which is formed in the bottom of a lower cavity of a lower die. The venting plug comprises a flat top plate part and a tubular body part, wherein the body part is matched with the venting hole, the top plate part is provided with a plurality of venting holes, and the openings in the lower ends of the venting holes are bigger than those in the upper ends. Furthermore, the venting holes are stripe-type venting holes, the cross section of which is an isosceles trapezoid. The venting holes of the venting plug provided by the utility model are arranged in a mode of narrow upper ends and wide lower ends, so that condition that gravels always block the venting holes is avoided. The venting plug provided by the utility model is relatively convenient to clean, and can be repeatedly used after being cleaned, so that not only are production efficiency and product quality improved, but also the repair cost is lowered.
Description
Technical field
The utility model relates to a kind of venting plug, relates in particular to a kind of venting plug for casting technique.
Background technology
Casting is a kind of metal fever processing technology, is the mold that the metal of melting is poured given shape into to be treated the processing method of its coagulation forming.In when casting, produce the defectives such as pore in the foundry goods, the gas that produces in casting process need to be discharged to beyond die cavity.Existing casting die cast and sand casting are to offer in the bottom surface of its lower impressions and the extraneous steam vent that is connected is used for exhaust, and venting plug is set in steam vent.In process of production, a lot of tiny grit can be arranged all on cavity surface, these tiny grit are easy to enter in steam vent and venting plug are stopped up, and generation is felt suffocated, and causes underproof product; Venting plug after stopping up simultaneously can't be cleared up, and needs often to change, and has affected product quality, has increased maintenance cost, therefore needs a kind of grit that can reduce to stop up, the venting plug that improves the quality of products.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of grit that can reduce to stop up, and the casting venting plug that improves the quality of products is to overcome the defects of prior art.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of venting plug for casting technique, described venting plug is arranged on the upper end of steam vent, described steam vent is opened in the lower impressions bottom of counterdie, described venting plug comprises the body of flat top plate portion and circular tube shaped, described body matches with steam vent, and top plate portion is provided with a plurality of exhaust outlets, and the lower ending opening of described exhaust outlet is greater than upper end open.
Preferably, described top plate portion is arranged on the upper surface of body.
Further, described exhaust outlet is the bar shaped exhaust outlet, and the cross section of bar shaped exhaust outlet is isosceles trapezoid.
As mentioned above, a kind of venting plug for casting of the present utility model, have following beneficial effect: the exhaust outlet of this device venting plug adopts the up-narrow and down-wide mode of offering, and has prevented that grit from stopping up exhaust outlet, simultaneously, if adhered to a small amount of grit in exhaust outlet, because exhaust outlet is gradient, cleaning is got up also more convenient, can Reusability after cleaning, not only improve production efficiency and product quality, also reduced repair cost.

The specific embodiment
The structure that Figure of description illustrates, ratio, size etc., equal contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, be not to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this specification as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the utility model.
Casting mould general in casting is divided into upper die and lower die, has upper impression and lower impressions on upper die and lower die, and upper and lower die cavity forms the mechanical part mold cavity that will cast jointly.Casting technique can produce gas when casting, if these gases can not in time be discharged the quality that mold cavity will affect product, so when in time discharging casting, the gas in mold cavity is very important.Mold cavity can have exhaust outlet and be used for Exhaust Gas, and exhaust outlet generally is opened on counterdie.Fig. 1 is the structure chart of a kind of venting plug for casting technique of the utility model, described venting plug 3 is arranged on the upper end of steam vent 2, described steam vent 2 is opened in lower impressions 11 bottoms of counterdie 1, described venting plug 3 comprises the body 32 of flat top plate portion 31 and circular tube shaped, described body 32 matches with steam vent 2, top plate portion 31 is provided with a plurality of exhaust outlets 33, and the lower ending opening of described exhaust outlet 33 is greater than upper end open.Lower ending opening is to make the grit that enters exhaust outlet 33 from upper end open directly to fall from exhaust outlet 33 greater than the purpose of upper end open, and discharges from steam vent 2.Certainly, in actual production, inevitably have a small amount of grit and stick on exhaust outlet 33, but a small amount of grit is can not affect exhaust, because exhaust outlet 33 lower ends are larger, so cleaning exhaust outlet 33 is also more convenient.Top plate portion 31 described in the present embodiment is arranged on the upper surface of body 32, like this when casting can not allow grit too much enter exhaust outlet 33, also played simultaneously the supporting role to metal liquid at steam vent 2 places, too large variation does not occur in the shape of having guaranteed casting model, based on this, venting plug 3 should be made with exotic materials such as potteries.
The described exhaust outlet 33 of this device can be the shape such as circular, square, as shown in Figures 2 and 3, exhaust outlet 33 described in the present embodiment is the bar shaped exhaust outlet, the cross section of bar shaped exhaust outlet is isosceles trapezoid, and draw desirable shape through practical operation, namely the angle between described isosceles trapezoid two waists is 6 °.
In sum, a kind of venting plug for casting of the utility model can solve the problem that in casting cycle, venting plug stops up, and easy cleaning.So, corresponding value is arranged aspect Foundry Production and uses meaning thereby the utility model has effectively overcome practical problems more of the prior art.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.The utility model also many aspects can also improve under the prerequisite of overall thought.All can under spirit of the present utility model and category, can modify or change above-described embodiment for person skilled in the art scholar.Therefore, have in technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of completing under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
