Abstract
The utility model relates to a mould for an extrusion casting bearing cover, which comprises an upper pressure head, an upper cover board, a forming mould chamber and a mould base and is characterized in that a mould base plate and a puncher pin are fixedly connected to form a pressure head body, a pressure column is fixed outside a puncher pin under the mould base plate and erected on the upper cover board. The upper cover board is formed by an upper pressing plate and a pressing ring under the upper pressing board, the outer wall of the pressing ring is matched with the inner wall of a mould bushing of the forming mould chamber closely, the inner wall of the pressing ring is matched with the puncher pin of the upper pressure head closely, and the upper cover board is erected on the forming mould chamber. The mould for the extrusion casting bearing cover is suitable for aluminum liquid filling flow forming, close to the usage size of work pieces, and improves usage rate of materials greatly. A floating design of the mould can enable the work piece to be solidified under pressure exerted vertically, improves performance greatly, and is convenient to operate, flexible in usage and high in efficiency.
Description
Technical field
The utility model relates to power transmission and transforming equipment, and the squeeze casting mould of parts one bearing cap of a kind of few innage on compressing switch is provided especially.
Background technology
It is general product in the forceful electric power high-voltage switch gear more than 63 kilovolts that few innage compresses switch, wherein bearing cap is to process with copper alloy cast form is ultimate, its material cost height, and weight is not light brings certain difficulty with aluminium alloy Alloy instead of Copper alloy a kind of good scheme of can yet be regarded as to installation.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 utility model content
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 bearing cap mould of end properties.
The technical solution adopted in the utility model:
It comprises seaming chuck, upper cover plate, shaping mold cavity, mould seat, and seaming chuck backing plate and drift be affixed to become seaming chuck, and seaming chuck backing plate below drift is fixed with the post of exerting pressure outward, and the post of exerting pressure is erected on the upper cover plate; Upper cover plate is made of top board and the pressure ring that is fixed in the top board below, and the die bush inwall of pressure ring outer wall and shaping mold cavity closely cooperates, and the drift of pressure ring inwall and seaming chuck closely cooperates, and upper cover plate is erected on the shaping mold cavity; Shaping mold cavity is formed by die coat, die bush and mould upper cover plate involution, and die coat is connected with mould seat elasticity by first spring; Fixedly install the blank ring on the mould seat, blank ring outer wall matches with die bush, inwall matches with drift, also be provided with in addition in the blank ring one with the close-fitting lower bolster of blank ring, lower bolster underlying one push rod, push rod is with second spring outward, and second spring is imbedded in the mould seat and with the mould seat and fixed.
The technique effect that the utility model is obtained:
1. the utility model is suitable for aluminium liquid and fills the shape flow forming, uses size near workpiece, and stock utilization is increased substantially; The design is floating type, can realize pressurizeing up and down workpiece is solidified under pressure, and performance greatly improves; The design is easy to operate, uses flexibly the efficient height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Referring to Fig. 1, a kind of extrusion casint bearing cap mould, it comprises seaming chuck 1, upper cover plate 2, shaping mold cavity 3, mould seat 4, seaming chuck backing plate 11 and drift 12 be affixed to become seaming chuck, seaming chuck backing plate below drift is fixed with the post 13 of exerting pressure outward, and the post of exerting pressure is erected on the upper cover plate; Upper cover plate is made of top board 21 and the pressure ring 22 that is fixed in the top board below, and die bush 32 inwalls of pressure ring outer wall and shaping mold cavity closely cooperate, and the drift of pressure ring inwall and seaming chuck closely cooperates, and upper cover plate is erected on the shaping mold cavity; Shaping mold cavity is formed by die coat 31, die bush 32 and mould upper cover plate 33 involutions, and die coat 31 is connected with mould seat elasticity by first spring 34; Fixedly install blank ring 41 on the mould seat, blank ring outer wall matches with die bush, inwall matches with drift, also be provided with in addition in the blank ring one with the close-fitting lower bolster 42 of blank ring, lower bolster underlying one push rod 43, push rod is with second spring, 44, the second springs outward and imbeds in the mould seat and with the mould seat and fix.
In use, after aluminium liquid poured into the shaping die cavity, seaming chuck descended, and the pressure head punch is divided contact aluminium liquid, 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 knock-pin resets, and the material cake of staying in the die cavity is ejected, and has finished the extrusion casint process one time, has prepared a shaping stock.
Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model also comprises these changes and is out of shape interior.
