The accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram that the present invention manufactures the entering and exhaust channel core of cylinder cap mould used.
The A-A cutaway view that Fig. 2 is Fig. 1 (mould six cavity configurations).
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the invention will be further described.
The entering and exhaust channel core manufacture method of cylinder cap of the present invention is: at first, (on casting Technology Design) need become the air flue core design of four cylinders (engine) cylinder cap the exhaust duct core of air intake duct core and two (part) disjunctor of two (part) disjunctor, then, on Design of Dies, (according to the installation dimension of shell core equipment and the zone of penetrating sand, require) to become double end to penetrate sand formula one mould six cavity configurations (as shown in Figure 1 and Figure 2) Design of Dies used, three (part) linkage row air flue core die cavity (31,32,33) is designed in the other end of mould design three (part) disjunctor air intake duct core die cavity (21,22,23), mould, then, (advancing, when the exhaust duct core is manufactured) need be adjusted the operation sequence of shell core equipment used, its operating procedure order is as follows: matched moulds → blasting unit sand (to form three disjunctor air intake duct cores) → retreat → shell core of blasting unit Whole Equipment (clockwise) that advances → penetrate turns over turnback → shell core vibrations → blasting unit sand (to form three linkage row air flue cores) → retreat → Whole Equipment of blasting unit (counterclockwise) reverse flip 180 degree → shell cores that advance → penetrate and shake → solidify → starts mould → dynamic model (clockwise) and turn over turn 90 degrees → dynamic model top board and eject prepared three disjunctors of while and advance, exhaust duct core → take out this core → reset → dynamic model of dynamic model top board (counterclockwise) reverse flip 90 degree → matched moulds, enter the lower whorl circulation.
As shown in Figure 1 and Figure 2, the present invention manufactures the entering and exhaust channel core mould used of cylinder cap, comprise die ontology 1, described die ontology 1 has double end and penetrates sand formula a multi-cavity mold (six chambeies) structure, and die ontology other end with (three) disjunctor air intake duct core die cavity 2, die ontology has (three) linkage row air flue core die cavity 3.
Above-mentioned mentioned shell core equipment need possess following functions: at first, shell core equipment has left and right die sinking, vertical sand shooting sand, can carry out the basic function such as shell core by vibrations; Secondly, shell core equipment (dynamic model and cover half) can integral body turn over turnback clockwise and counterclockwise, and the dynamic model of shell core equipment can integral body turn over and turn 90 degrees clockwise and counterclockwise, and with automatic ejection and the function such as reset; Finally, the operating sequence of shell core equipment has adjustable function, can adjust to operating sequence of the present invention and carry out operation task.
Above-mentioned mentioned double end is penetrated sand formula mould, need in die design process to consider that blasting unit is when being penetrated sand respectively to mould two, the position of its loophole can not change, therefore in Design of Dies, need to be arranged in the loophole position at mould two symmetrical, the uniformity of loophole position while to reach the mould double end, penetrating sand.It is symmetrical to be to arrange in loophole position, two that described double end is penetrated sand formula die ontology 1, cover half, its right side mould sole 5 dynamic model (as shown in Figure 1) for set casing core equipment be installed of its left side mould sole 4 for the set casing core equipment is installed.
The operating sequence that above-mentioned mentioned double end is penetrated sand is: first the disjunctor air intake duct core die cavity of mould is penetrated to sand, again the linkage row air flue core die cavity of mould is penetrated to sand, because disjunctor air intake duct core is larger than the volume of linkage row air flue core, relatively will grow required hardening time, therefore need first disjunctor air intake duct core die cavity to be penetrated to sand on operating sequence, then linkage row air flue core die cavity is penetrated to sand.
In above-mentioned mentioned operating sequence, because mould adopts mould six cavity configuration designs, get the process of core after die sinking and need consider that operating personnel get operability and the convenience of core, therefore need shell core equipment to there is dynamic model after starting mould and turn over clockwise again the function turn 90 degrees, dynamic model turns over clockwise and turn 90 degrees rear horizontal-top and go out core, so extracts the core process and just becomes very simple and reliable.
