Abstract
The utility model belongs to the field of production of car fuel injection pumps, and particularly relates to a fuel injection pump cross loose core type mould. The fuel injection pump cross loose core type mould comprises a mould core, a mould frame, sliders and a loose core, wherein the mould core, the mould frame, the sliders and the loose core are successively connected. The mould core comprises an fuel tube mould core and a fuel pump hole mould core. A through groove is arranged in the fuel pump hole mould core. Due to the fact that the fuel tube is arranged in such a manner that the fuel tube penetrates the fuel pump hole mould core through the through groove, during casting or pouring, a post forming is prevented and an air hole and a crack are avoided. Meanwhile, the wall thickness of the fuel tube can be kept even. Two ends of the fuel tube mould core are respectively connected with a slider a and a slider b. The slider a is connected with a loose core e and the slider b is connected with a loose core f. Two ends of the fuel pump hole mould core are respectively connected with a slider c and a slider d. The slider c is connected with a loose core g and the slider d is connected with a loose core h. Therefore, a loose core process can bidirectionally conduct and is fast and rapid.
Description
Technical field
The utility model belongs to automobile injection pump and makes the field, relates in particular to a kind of mould of injection pump cross core-loosing.
Background technology
The injection pump structure is comparatively complicated, and casting is generally adopted in its processing and manufacturing.Injection pump is provided with the oilhole that larger oil pump hole, aperture and a plurality of aperture are less and be parallel to each other, described oil pump hole and oilhole are through hole, and each oilhole all communicates with the oil pump hole, and oilhole is divided into two sections by the oil pump hole like this, forms the stephanoporate thin wall structure at the pump housing.For oil pump hole and oilhole, when carrying out Design of Dies, just faced so-called " cross core-loosing " problem.Present mould structure substantially be oil pump casement core is done as a whole, and with the oilhole core rod take the core rod in oil pump hole as the boundary, be divided into two sections and loose core respectively.This structure causes tubing wall discontinuous owing to building, and the even phenomenon of pore, crack and wall unevenness easily occurs, causes the injection pump qualification rate very low.
The utility model content
The utility model provide a kind of can overcome the even injection pump cross core-loosing formula mould of pore, crack, wall unevenness appears when injection pump is loosed core.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: injection pump cross core-loosing formula mould, comprise successively the core rod that connects, framed, slide block, loose core, described core rod comprises oil pipe core rod and oil pump casement core, oil pump casement core is provided with and runs through groove, the oil pipe core rod runs through the setting of oil pump casement core by running through groove, oil pipe core rod two ends are connection sliding block a and slide block b respectively, slide block a connects the e of loosing core, slide block b connects the f of loosing core, oil pump casement core two ends are connection sliding block c and slide block d respectively, and slide block c connects the g of loosing core, and slide block d connects the h of loosing core.
Adopt technique scheme, in the utility model, core rod comprises oil pipe core rod and oil pump casement core, oil pump casement core is provided with and runs through groove, and the oil pipe core rod runs through the setting of oil pump casement core by running through groove, utilizes said structure can guarantee the integrality of oil pipe core rod profile, like this when die casting or cast, avoid the post forming of oil pipe, prevented pore, crack, can keep the wall thickness of oil pipe even simultaneously; Oil pipe core rod two ends are connection sliding block a and slide block b respectively, and slide block a connects the e of loosing core, and slide block b connects the f of loosing core, oil pump casement core two ends are connection sliding block c and slide block d respectively, and slide block c connects the g of loosing core, and slide block d connects the h of loosing core, when loosing core operation, can two-wayly carry out like this, quick like this, rapid.
Further, the cooling velocity that described framed cooling tower and the fixing guide pin bushing of being provided with, cooling column can accelerating liquids, fixedly guide pin bushing can make things convenient for the installation of mould, reduces simultaneously the damage of mould.
Further, the lower end of described core rod is provided with the material handle, makes mould can determine an accurately position on die casting machine.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
