Abstract
The utility model relates to a kind of bicavity mould for automobile engine cylinder-body cast, comprise two die cavities, each die cavity is provided with one for injecting cast gate and a rising head of discharging for type chamber air of liquid metal in die cavity, cast gate is arranged on cavity bottom, and rising head is arranged on die cavity top; Also comprise cast communicating pipe; Die cavity is communicated with cast gate and rising head, cast comprises middle M shape gate spool communicating pipe and is arranged on the U-shaped gate spool of M shape gate spool both sides, one end of two U-shaped gate spools is communicated with the footing of the M shape of M shape gate spool respectively, the other end of two U-shaped gate spools is connected with the cast gate of two die cavities respectively, and the footing in the middle part of the M shape of M shape gate spool is sprue gate.The sprue gate of liquid metal from M shape gate spool is injected by the utility model, and after the die cavity that liquid metal is full of both sides, stop cast, the air in die cavity is discharged from the rising head at die cavity top; Cast gate is parallel with rising head and all vertically arrange, smooth in exhaust, improves casting quality.
Description
Technical field
The utility model relates to mould for metal casting technical field, particularly a kind of bicavity mould for automobile engine cylinder-body cast.
Background technology
Cylinder body is conventional part, due to complex structure, usually adopts casting method manufacture.Mould conventional at present has die cavity, cast gate and rising head, cast gate is used for injecting liquid metal in die cavity, and rising head is used for the discharge of type chamber air, and die cavity is communicated with cast gate and rising head, in cast gate and rising head, at least one is horizontally disposed, and cast gate is mutually vertical with rising head mostly.Because the inflow direction of liquid metal is vertical with the discharge direction of air, when liquid metal injects, there will be turbulent flow, cause leaking.In addition, one of cast gate and rising head are horizontally disposed with, and are unfavorable for the discharge of type chamber air.
Utility model content
The technical problems to be solved in the utility model is: discharge to overcome type chamber air the deficiency had some setbacks, and the utility model provides a kind of bicavity mould for automobile engine cylinder-body cast.
The utility model solves the technical scheme that its technical problem adopts: a kind of bicavity mould for automobile engine cylinder-body cast, comprise two die cavities, each die cavity is provided with one for injecting cast gate and a rising head of discharging for type chamber air of liquid metal in die cavity, described cast gate is arranged on cavity bottom, and described rising head is arranged on die cavity top;
Also comprise cast communicating pipe;
Described die cavity is communicated with cast gate and rising head, described cast comprises middle M shape gate spool communicating pipe and is arranged on the U-shaped gate spool of M shape gate spool both sides, one end of two U-shaped gate spools is communicated with the footing of the M shape both sides of M shape gate spool respectively, the other end of two U-shaped gate spools is connected with the cast gate of two die cavities respectively, and the footing in the middle part of the M shape of described M shape gate spool is sprue gate.
The side that described U-shaped gate spool is connected with cast gate is vertically arranged.
The central axis of cast gate and the central axes of rising head.
The beneficial effects of the utility model are, bicavity mould for automobile engine cylinder-body cast of the present utility model, the sprue gate of liquid metal from M shape gate spool is injected, cast is stopped after the die cavity that liquid metal is full of both sides, air in die cavity is discharged from the rising head at die cavity top, and once-cast can be made into two pieces finished product; Cast gate is parallel with rising head and all vertically arrange, and makes away material smooth and easy, and because air upwards emits in liquid metal, discharge from rising head with finally making air natural, smooth in exhaust, improves casting quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of the optimum embodiment of the bicavity mould for automobile engine cylinder-body cast of the present utility model.
In figure 1, die cavity, 2, cast gate, 3, rising head, 4, cast communicating pipe, 4-1, M shape gate spool, 4-2, U-shaped gate spool, 4-3, sprue gate.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of bicavity mould for automobile engine cylinder-body cast of the present utility model, comprise two die cavities 1, each die cavity 1 is provided with one for injecting cast gate 2 and a rising head 3 of discharging for air in die cavity 1 of liquid metal in die cavity 1, described cast gate 2 is arranged on bottom die cavity 1, and described rising head 3 is arranged on die cavity 1 top.
Also comprise cast communicating pipe 4, described die cavity 1 is communicated with cast gate 2 and rising head 3, described cast comprises middle M shape gate spool 4-1 communicating pipe 4 and is arranged on the U-shaped gate spool 4-2 of M shape gate spool 4-1 both sides, one end of two U-shaped gate spool 4-2 is communicated with the footing of the M shape both sides of M shape gate spool 4-1 respectively, the other end of two U-shaped gate spool 4-2 is connected with the cast gate 2 of two die cavities 1 respectively, and the footing in the middle part of the M shape of described M shape gate spool 4-1 is sprue gate 4-3.
Injected at the sprue gate of liquid metal from M shape gate spool 4-1, after the die cavity 1 that liquid metal is full of both sides, stop cast, the air in die cavity 1 is discharged from the rising head 3 at die cavity 1 top, and once-cast can be made into two pieces finished product; Cast gate 2 is parallel with rising head 3 and all vertically arrange, and makes away material smooth and easy, and because air upwards emits in liquid metal, discharge from rising head with finally making air natural, smooth in exhaust, improves casting quality.
The side that described U-shaped gate spool 4-2 is connected with cast gate 2 is vertically arranged, the central axis of cast gate 2 and the central axes of rising head 3.Like this, make liquid metal feedstock direction and discharging direction in a straight line, walk material and be vented more smooth and easy.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
