Abstract
The utility model relates to a core making device of an engine casting system and in particular relates to a side-pulling structure of a core box for a core making center of an engine. The side-pulling structure of the core box for the core making center of the engine comprises an upper core box, a side-pulling sealing strip, a side-pulling mechanism and a lower core box, wherein the side-pulling mechanism comprises an upper junction surface, a lower junction surface and a side junction surface; the upper half part of the side junction surface is an oblique plane; the lower part of the side junction surface is a table surface; a slot is formed in the side of the upper core box; the upper part of the inner side is trapezoidal; the upper junction surface of the side-pulling mechanism is jointed with the slot; a sealing groove and an inner side-pulling sealing strip are arranged on the upper junction surface of the slot; the sealing groove and the side-pulling sealing strip are trapezoidal. The side-pulling structure has the advantages that the time for blowing amine to a sand core and curing the sand core is reduced, the production efficiency is improved, the consumption of triethylamine is reduced, the waste of the energy source is avoided, and the cost is saved.
Description
Technical field
The utility model relates to a kind of engine casting system coremaking equipment, is specially a kind of engine Core making center core box side core-pulling structure.
Background technology
What Core making center adopted at present is triethylamine cold core box process, for level is divided box, device systems is divided into mixing system, penetrate sand system, scavenger system, side is taken out pulling mechanism system, core box main body mechanism, wherein core box main body mechanism is divided into again core box mechanism, lower core box mechanism and side pulling mechanism, its motion workflow is: in mulling-side pulling mechanism and lower core box matched moulds-drive into equipment-upper core box and lower core box and the whole matched moulds of side pulling mechanism-penetrate sand-airs blowing-side pulling mechanism to open-go up core box the release-reciprocal next one of open-lower core box circulates, the adaptive core box structure of equipment of using is shown in Fig. 1.We find in daily production, when upper core box and lower core box and side pulling mechanism matched moulds, due to lower core box and side pulling mechanism matched moulds at first, and the sealing strip of side pulling mechanism has part to exceed lower core box mechanism (design needs), see the seal form in partial enlarged drawing 2, core box side pumping board contacts with upper and lower core box outer rim, and sealing strip is arranged on core box run location.When upper core box and its matched moulds, the former sealing strip in the upper strata of side pulling mechanism can be cut away, thereby cause this position poorly sealed, when scavenger system is worked, this position gas leakage, cause local core not solidify, affect production efficiency, and the triethylamine in scavenger system is pernicious gas, can causes serious environmental pollution, operating personnel are caused to physical impairment, so need address this problem in a hurry.
Summary of the invention
The utility model breaks the sealing strip that side is taken out position when solving upper core box matched moulds, causes core box gas leakage problem, and a kind of engine Core making center core box side core-pulling structure is provided.
The technical solution of the utility model is, a kind of engine Core making center core box side core-pulling structure, comprises core box, and side is taken out sealing strip, side pulling mechanism, lower core box, described side pulling mechanism comprises upper connecting surface, lower junction, side joint face, side joint face the first half is inclined-plane, bottom is divided into table top; The side of upper core box is slot, and inside upper part is trapezoidal shape.Described side pulling mechanism upper connecting surface and slot engage, and the side that is provided with seal groove and inside at slot upper connecting surface is taken out sealing strip, and it is trapezoidal that described seal groove and side are taken out sealing strip.
The beneficial effects of the utility model: it is inner that the side pulling mechanism after improvement extends to upper and lower core box frame, by side, change to end face with the contact-making surface of upper core box, side is taken out face and is coordinated tightly with upper and lower core box, can effectively intercept Leakage Gas and seal at the top of side pulling mechanism, prevent core box matched moulds cutting sealing bar.Reduced core and blown amine, hardening time, enhanced productivity.Reduction is to the pollution of environment and the injury to operator.Sealing strip is changed the frequency and is reduced; Triethylamine consumption reduces; Avoid the waste of the energy; Cost-saving.
Accompanying drawing explanation
Fig. 1 is existing coremaking mechanism structural representation
Fig. 2 is the partial enlarged drawing of Fig. 1
Fig. 3 is structural representation of the present utility model
Fig. 4 is the partial enlarged drawing of Fig. 3
The upper core box of 1-in figure, the former sealing strip of 2-, 3-side pulling mechanism, core box under 4-, 5-side is taken out sealing strip.
The specific embodiment
As shown in Figure 3,4 views, a kind of engine Core making center core box side core-pulling structure comprises core box 1, and side is taken out sealing strip 5, side pulling mechanism 3, lower core box 4, described side pulling mechanism 3 comprises upper connecting surface, lower junction, side joint face, side joint face the first half is inclined-plane, bottom is divided into table top; The side of upper core box 1 is slot, and inside upper part is trapezoidal shape.
Described side pulling mechanism 3 upper connecting surfaces and slot engage, and the side that is provided with seal groove and inside at slot upper connecting surface is taken out sealing strip 5, and described seal groove and side are taken out sealing strip 5 for trapezoidal.
So, side pulling mechanism 3 first with the first matched moulds of lower core box, then go up that core box moves downward and lower core box closes while touching, side pulling mechanism and a part of plane contact of upper core box 1, the contact of another part inclined-plane, does not produce relative motion, side is taken out sealing strip and can be cut, and has guaranteed that sealing is tight.
