Description
Technical field
The utility model relates to automobile engine cylinder-body water jacket production technical field, specifically is a kind of cylinder body water jacket core mold of automobile engine.
Background technology
The automobile engine cylinder-body sand core of water jacket mould of prior art; Its structure generally comprises underframe, following core box, goes up core box and penetrate sand mechanism; Described going up between core box and the following core box is provided with cylinder body water jacket core die cavity, and said core box down is provided with the following plunger tip bar of sand core of water jacket.When carrying out the cast blocks water jacket with the cylinder body water jacket core; Need with screw stationary housing sand core of water jacket; The cylinder body water jacket core that the automobile engine cylinder-body sand core of water jacket die production of prior art is come out is not reserved the tap hand-hole; When screw is shot in the cylinder body water jacket core, can be from the tap hand-hole knockout downwards, thereby cause the cylinder body water jacket core fixing not firm; Moreover, and be easy to cause core to break because the automobile engine cylinder-body sand core of water jacket is a kind of thin-wall product, make the cylinder body water jacket core imperfect, even situation such as fracture.And because cylinder body water jacket core die cavity is narrower and small; When penetrating sand mechanism when in the sand core of water jacket die cavity, filling sand; Air in the cylinder body water jacket of engine core die cavity can not in time be discharged; Thereby can cause the sand core of water jacket die cavity to be not fully filled sand, so also have a strong impact on the Forming Quality of automobile engine cylinder-body sand core of water jacket.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provides a kind of cylinder body water jacket core die cavity that can make to be full of sand fast, and makes the cylinder body water jacket core have the cylinder body water jacket core mold of the automobile engine of reserving the tap hand-hole.
The technical solution of the utility model is; A kind of cylinder body water jacket core mold with automobile engine of following structure is provided: it comprises underframe, last core box, following core box, plunger tip bar, plunger tip plate and penetrates sand mechanism; Said going up between core box and the following core box is provided with cylinder body water jacket core die cavity; The upper surface of said plunger tip bar is equal with cylinder body water jacket core cavity bottom, and the lower end of plunger tip bar is fixedly connected with the plunger tip plate, and said core box down bottom is provided with the circular indent with plunger tip bar coaxial line; Described circular indent is connected with the bottom of cylinder body water jacket core die cavity; And be provided with the venting plug of a band centre bore in the circular indent, described venting plug is connected with the inwall of circular indent is removable, the top of said plunger tip bar and venting plug centre bore matched in clearance; The upper surface of said venting plug is provided with a plurality of steam vents, and venting plug is provided with the annular exhaust passage that is connected with a plurality of steam vents; Described plunger tip bar is the plunger tip bar that has centre bore, and the centre bore internal clearance of said plunger tip bar cooperates a thimble, and the top of said thimble is positioned at cylinder body water jacket core die cavity, and the lower end of thimble is fixedly connected on the fixed head of underframe.
After adopting above structure; The cylinder body water jacket core mold of a kind of automobile engine of the utility model compared with prior art; Have the following advantages: when penetrating sand mechanism when in the sand core of water jacket die cavity, filling sand; The venting plug that is provided with on the cylinder body water jacket core cavity bottom plunger tip bar of this automobile engine cylinder-body sand core of water jacket mould; Can the air in the cylinder body water jacket of engine core die cavity in time be discharged, make cylinder body water jacket core die cavity be full of sand fast, thereby make the Forming Quality of automobile engine cylinder-body sand core of water jacket high; In addition; The cylinder body water jacket core mold of this automobile engine is when the plunger tip plate upwards drives the plunger tip masthead and plays the cylinder body water jacket core; Cylinder body water jacket core bottom breaks away from thimble top, thus the tap hand-hole that under reserving on the cylinder body water jacket core, matches with thimble shaped upper part and size, and this tap hand-hole is with screw stationary housing sand core of water jacket the time; Can make things convenient for screw to shoot; With regard to not causing core to break or making situation such as the cylinder body water jacket core is imperfect, fracture, when the stationary housing sand core of water jacket, guaranteed the complete of cylinder body water jacket core like this.
As a kind of improvement; The top of said thimble is up-small and down-big taper; And the top of thimble comprises first section, second section and the 3rd section from top to bottom in proper order; Said first section tapering is less than second section tapering, and second section tapering is less than the 3rd section tapering, and the 3rd section upper end diameter is greater than the fixing diameter of the screw of core.So after thimble top breaks away from the cylinder body water jacket core; The tap hand-hole of reserving on the cylinder body water jacket core also forms the three different sector holes of tapering that match with thimble top; The following sector hole of this three sector hole can make things convenient for the screw location; And the molding sand that screw drops in the tap hand-hole when tightening also can drop in the following sector hole, can in the hole, not spill, thereby has guaranteed the fix tightly solidity of cylinder body water jacket core.
As a kind of improvement, the lower end of said venting plug is provided with an annular pressing plate, and described annular pressing plate is fixedly connected through holding screw with following core box, and the centre bore of annular pressing plate is connected with the annular exhaust passage of venting plug.After venting plug is installed, compress bottom the venting plug with the annular pressing plate, take off venting plug and only need unclamp holding screw and get final product.
