Description
The utility model relates to power transmission and transforming equipment, and parts--the squeeze casting mould of-trim ring of a kind of few innage on compressing switch is provided especially.
It is general product in the forceful electric power high-voltage switch gear more than 63 kilovolts that few innage compresses switch, wherein trim ring is to process with copper alloy cast form is ultimate, its material cost height, and weight is not light, bring certain difficulty to installation, with aluminium alloy Alloy instead of Copper alloy a kind of good scheme of can yet be regarded as.But, use its electrical property of cast aluminium and mechanical performance all not to reach requirement, can not adopt casting method with high strength alumin ium alloy, as adopt ingot casting, Forging Technology, then cost increases substantially, and stock utilization is low, selectable preferred plan is extrusion casint, it has the easy shaping of casting, and shaped blanks is near the actual size of parts, and processing capacity is few, make parts have forgeability again, the advantage that meets design requirement.And in the Extrution casting technique process, the most important thing is the mould design, mould designs well, can improve finished product productivity ratio greatly, improves stock utilization and material property.
The purpose of this utility model is to provide a kind of finished product productivity ratio height, stock utilization height, and the good extrusion casint trim ring mould of end properties.
The utility model provides a kind of extrusion casint trim ring mould, is made up of seaming chuck (1), upper cover plate (2), shaping mold cavity (3), mould seat parts such as (4), it is characterized in that:
Drift (12) is following convex, becomes seaming chuck (1) with seaming chuck backing plate (11) is affixed, and drift (2) flange place is erected on the upper cover plate (2);
Upper cover plate (2) is made of top board (21) and the pressure ring (22) that is fixed in its below, die bush (32) inwall of pressure ring (22) outer wall and shaping mold cavity (3) closely cooperates, the drift (12) of its inwall and seaming chuck (1) closely cooperates, and upper cover plate (2) is erected on the shaping mold cavity (3);
Shaping mold cavity (3) is formed by mould upper cover plate (33) involution by die coat (31) inner lining film tool liner (32) again, and die coat (31) is connected with mould seat (4) elasticity by spring A (34);
Fixedly install blank ring (41) on the mould seat (4), blank ring (41) outer wall matches with die bush (32), and inwall matches with drift (12); One lower bolster close-fitting with it (42) is set in the blank ring (41) in addition, lower bolster (42) underlying one push rod (43), push rod (43) is outer to be with spring B (44) and to pass mould seat (4) and be fixed on the spring-support plate (45).
In use, after aluminium liquid poured into the shaping die cavity, seaming chuck descended, and the pressure head punch is divided contact aluminium liquid, from aluminium liquid is risen, be full of the shaping die cavity, at this moment upper cover plate is enclosed in aluminium liquid in the die cavity, and seaming chuck continues to descend, pressure acts on the aluminium liquid by upper cover plate, aluminium liquid contacts with die cavity wall, pushed by active force, up to solidification forming.At this moment some aluminium liquid becomes the material cake, is cut off by drift and cutting ring.When seaming chuck lifted, upper cover plate was bound round on the aluminum component on the pressure head drives together and is moved, and after aluminum component all proposes forming cavity, promoted upper cover plate by cover workpiece stripper apparatus correspondingly and moved down aluminum component is pushed from drift, broke away from drift.Then, following backing-out punch is up, the material cake of staying in the die cavity is ejected, and will descend backing-out punch and upper cover plate to reset, and has finished the extrusion casint process one time, has prepared a shaping stock.In a word, the utlity model has following advantage:
1. have unsteady characteristics, reality two-way extruding up and down, finished product density height, good mechanical property;
Mould in use nimbly and freely, the efficient height;
3. workpiece has the most approaching size that makes appliance, makes machining time saving and energy saving as far as possible; And improved stock utilization greatly.
By embodiment in detail the utility model is described in detail below in conjunction with accompanying drawing

Embodiment
As shown in Figure 1, trim ring is made up of seaming chuck (1), upper cover plate (2), shaping mold cavity (3), mould seat parts such as (4) with mould, drift (12) is following convex, becomes seaming chuck (1) with seaming chuck backing plate (11) is affixed, and drift (2) flange place is erected on the upper cover plate (2); Upper cover plate (2) is made of top board (21) and the pressure ring (22) that is fixed in its below, die bush (32) inwall of pressure ring (22) outer wall and shaping mold cavity (3) closely cooperates, the drift (12) of its inwall and seaming chuck (1) closely cooperates, and upper cover plate (2) is erected on the shaping mold cavity (3); Shaping mold cavity (3) is formed by mould upper cover plate (33) involution by die coat (31) inner lining film tool liner (32) again, and die coat (31) is connected with mould seat (4) elasticity by spring A (34); Fixedly install blank ring (41) on the mould seat (4), blank ring (41) outer wall matches with die bush (32), and inwall matches with drift (12); One lower bolster close-fitting with it (42) is set in the blank ring (41) in addition, lower bolster (42) underlying one push rod (43), push rod (43) is outer to be with spring B (44) and to pass mould seat (4) and be fixed on the spring-support plate (45).
Its operating process is as follows:
The mould seaming chuck is made up of (11) (12) part, and the press upper mould beam is up, and mold open injects molten metal aluminium liquid in die bush (32).The press entablature is descending then, pressure ring (22) contacts with mould upper cover plate (33) with pressing plate (21), the press sill continues descending, drift (12) flange contacts with pressing plate (21), drift (12) is with aluminium liquid extrusion molding, and with pressing plate (21) jack-up, and the pressure of drift (12) is applied on the aluminium liquid by pressing plate (21) and pressure ring (22), aluminium liquid solidifies under pressure.
When pressure is applied on the aluminium liquid, move down under the pressure of clamping cap (21), blank ring (41) relatively upwards squeezes and adds aluminium liquid, form the effect of co-extruded up and down, when drift (12) moves down above blank ring (41) upper edge, just will expect that cake cuts off, and breaks away from workpiece (5).
When aluminium liquid after solidifying under the pressure, the press crossbeam is up, and aluminum component (5) is owing to solidification shrinkage is bound round on drift (12), and is up with drift (12), transferred to mould and liner (32) to break away from, press continues up, and pressing plate (21) separates with drift (12), and drift (12) continuation is up, workpiece (5) compression plate (21) stops and can not be up, when drift (12) is up from workpiece, deviate from certain-length after because drift (12) has certain taper, workpiece breaks away from from drift.
Stay the material cake in the blank ring, upwards promoted, upwards push away blank ring (41), from mould, can take out easily by the ejecting mechanism that plays the oil cylinder (not shown) to promote.
Mould returns to original position naturally under the support of pillar spring (34) promotes.Suitably adjust mould, behind the spraying lubricant, can next circulate, pour into a mould next workpiece.
