Description
Technical field
The utility model relates to casting technology field, particularly the Removal Technology of casting mould.
Background technology
At present, a lot of foundry goods all adopt Iron Mould Coated Sand, and precoated sand generally adopts phenolic resins, will be defeated and dispersed under the condition of high temperature,Deadweight by sand comes off automatically from mould, but for the sand in the sand-spraying hole of swage mould, dependence deadweight can not be completely de-Fall, thereby also need later stage labor cleaning, therefore labour intensity is larger, and production cost also increases thereupon, and manual cleanup unavoidably canThere is the phenomenon of omission. At present, the mechanical type cleaning plant having occurred, it adopts plunger tip to insert in sand-spraying hole, by sand from mouldIn come off, this mode needs plunger tip to contact with the inwall of sand-spraying hole, in the time that sand is more, the squeezing action of plunger tip is to sand-spraying holeInner surface cause certain damage, thereby affect the normal use of mould.
Utility model content
The applicant, for the above-mentioned shortcoming of prior art, studies and improves, and a kind of rotary blowing of casting mould is providedKnockout head, it adopts air blowing type mode, and sand is come off from sand-spraying hole, and it uses safety, cleaning effect good.
In order to address the above problem, the utility model adopts following scheme:
A rotary blowing knockout head for casting mould, comprises holder, and the upper surface of holder is provided with lift cylinder, itsLower surface is provided with many plunger tips, and the position of plunger tip is corresponding with the position of sand-spraying hole, and described holder is hollow with inner chamberStructure, its upper surface is provided with the air inlet pipe being communicated with its inner chamber; Described plunger tip is rotationally connected by mounting head and holder, topCore is the tubular structure with air guide channel, and its sidewall is with being communicated with its air guide channel and multiple jet orifices setting up and down,The inclined of the relative plunger tip of jet orifice arranges downwards; Described mounting head is rotationally connected by bearing and holder, and it is with connectingThe venting cavity of logical inner chamber and air guide channel, the internal diameter of venting cavity is greater than the internal diameter of air guide channel; Driven gear is installed in mounting head,Adjacent mounting head is by described synchronous connection of driven gear engagement, and the driven gear of a side outermost end engages with driving gear, mainMoving gear is connected with drive motors by belt.
Further improvement as technique scheme:
Described plunger tip is connected by mounting head and holder, and described mounting head is with the venting cavity of communication with cavity and air guide channel, logicalThe internal diameter of air cavity is greater than the internal diameter of air guide channel.
The inner of described jet orifice is with flare.
Described air inlet pipe is can the flexible bellows structure of bending.
Technique effect of the present utility model is:
The utility model adopts jet-impingement mode that sand is come off from sand-spraying hole, compares the pushing method of plunger tip, has avoided penetratingThe damage of sand hole inwall, ensures knockout safety, reliable; The efficiency of spraying shakeout mode is also significantly improved, and it is effective;The rotary blowing of plunger tip is blown off to sand comprehensively, can save the number of spray-hole, simplifies its structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
In figure: 1, holder; 100, inner chamber; 2, lift cylinder; 3, plunger tip; 30, air guide channel; 31, jet orifice;32, enlarging; 4, air inlet pipe; 5, mounting head; 50, venting cavity; 6, bearing; 7, driven gear; 8, driving gear; 9,Drive motors; 10, belt.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
Embodiment mono-:
As shown in Figure 1, the rotary blowing knockout head of the casting mould of the present embodiment, comprises holder 1, holder 1 upperSurface is provided with lift cylinder 2, and its lower surface is provided with many plunger tips 3, and the position of plunger tip 3 is corresponding with the position of sand-spraying hole,Holder 1 is the hollow-core construction with inner chamber 100, and its upper surface is provided with the air inlet pipe 4 being communicated with its inner chamber 100; Plunger tip 3Be rotationally connected by mounting head 5 and holder 1, plunger tip 3 is the tubular structure with air guide channel 30, its sidewall withIts air guide channel 30 is communicated with and multiple jet orifices 31 setting up and down, and the inclined of jet orifice 31 relative plunger tips 3 is to dividing intoPut; Mounting head 5 is rotationally connected by bearing 6 and holder 1, and it is the venting cavity with air guide channel 30 with communication with cavity 10050, the internal diameter of venting cavity 50 is greater than the internal diameter of air guide channel 30, and venting cavity 50 transits to air guide channel 30, and entirety forms oneThroat structure, increases the air pressure of air guide channel 30, thereby increases the ejaculation pressure of jet orifice 31; In mounting head 5, be provided with fromMoving gear 7, adjacent mounting head 5 is passed through synchronous connection of driven gear 7 engagements, the driven gear 7 of a side outermost end and activeGear 8 engages, and driving gear 8 is connected with drive motors 9 by belt 10.
