Description

Elliptical shell aluminium section bar necking die

Technical field

The utility model is related to elliptical shell aluminium section bar necking dies.

Background technology

With the improvement of people's living standards, the requirement of the requirement, furniture for household, to its function, beautiful requirement Also higher, home theater, home audio are also more and more common, and current sound chamber is to pursue beautiful, improving grade in shape, and one As all use oval sound chamber, material to be generally aluminum alloy material.Oval speaker also, upper part of the housing have contracting Mouthful, if directly casting accuracy is bad, and the speaker reprocessing necking for first processing whole ellipse is not found also properly at present Method.

Utility model content

The purpose of this utility model is that overcoming defect existing in the prior art, elliptical shell aluminium section bar necking is provided Mold can process and meet elliptical shell aluminium section bar of the top of required precision with necking, and be not in damage top by pressure The case where necking.

To achieve the above object, the technical solution of the utility model is a kind of elliptical shell aluminium section bar necking die of design, Upper mold including upper die holder and for forming necking to elliptical shell top, detachable connection further include on upper die holder Lower die holder and lower moulded board for limiting upper mold movement position are arranged on lower die holder, and lower moulded board is equipped with two pieces, respectively Positioned at the both sides of elliptical shell short-axis direction.Upper die holder is driven to move downward to form contracting by the action of cylinder or hydraulic cylinder Mouthful.

Further technical solution is, upper mold include in set the cope plate of ladder elliptical hole and the upper mold of elliptical cylinder-shape Benevolence, cope plate quadrangle are connected by bolt with upper die holder, and upper cores are bolted to by least two on upper die holder, upper cores Shape be adapted with the interior shape after the necking of elliptical shell top, after ladder elliptical hole and the necking of elliptical shell top Outer shape is adapted.It is such to be arranged after the macropore of ladder elliptical hole first to be found accurately to elliptical shell before upper die holder pushes so Rear drive equipment action can be completed necking formation (since upper cores are located at the middle part of cope plate, just elliptical shell in this way In gap between upper cores and cope plate, with the downlink of upper die holder, by being equipped with ladder elliptical hole in the inner, therefore So that the top of elliptical shell gradually forms necking).

Further technical solution is that upper padding plate is additionally provided between upper mold and upper die holder, and three is bolted；It is described Setting and its integrally formed bottom seat pad, are fixedly installed lower bolster on lower die holder under lower die holder.

Further technical solution is that two pieces of sliding blocks in cuboid, lower moulded board lower part are fixedly installed on lower bolster Equipped with the matched protrusion of sliding block and recess, a side of lower moulded board is against elliptical shell, and another side is against in setting Mould slotting tool, the setting of upper mold slotting tool side are fixedly connected on lower bolster and lean on knife.Lower moulded board is slidably inserted by sliding block, due to The setting of its underpart protrusion and recess can prevent its movement in process, upper mold slotting tool upper mold after the completion easy to process Demoulding (i.e. so that upper mold is easily detached from elliptical shell).

Further technical solution is that lower die is arranged on lower bolster to take off plate, and lower die, which takes off to be equipped in the middle part of plate, is used for elliptical shell The ellipse hole that lower part is inserted into, lower die take off the both sides of plate against sliding block, and upper die and lower die pressing plate and lower die take off the height of plate three The sum of be equal to elliptical shell height.The setting of height can prevent upper die holder from declining too many and damaging upper part of the housing (this height by pressure Degree relationship makes upper mold at most drop to lower moulded board upper surface and can not just decline again).After upper moulding/demoulding by pushing up upwards under Mould, which takes off plate, can be readily accomplished the demoulding of lower moulded board.

Specifically action process is：Lower die is placed in the middle part of lower bolster and takes off plate, and elliptical shell, which is then placed on lower die, takes off plate Ellipse hole in (namely the lower contacts lower bolster of elliptical shell is equal to elliptical shell and is inserted into ellipse hole), Two pieces of lower moulded boards are inserted into along sliding block, such two pieces of lower moulded boards are inserted into against two sides of elliptical shell Mould slotting tool, two sides bear against lower moulded board and lean on knife, and upper mold, upper padding plate and upper die holder are then passed through connector such as spiral shell It tethers and connects, finding elliptical shell exhaust hood (piston rod of cylinder is fixedly connected with upper die holder) accurately by upper mold acts so that upper mold Seat push just complete the necking of elliptical shell top processing (for ensure processing stabilization can also upper die holder and lower die holder it Between guide post is set, upper die holder moves up and down along guide post, but in this way lower die take off plate position need to the aligned in position of upper mold/ It is adapted)；Upper mold is first taken off when demoulding, directly carries upper die holder upwards, due to leaning on knife, upper mold slotting tool, lower moulded board and oval shell Body (referring to its underpart) is stood tightly against, and at this moment upper die holder above carries just directly so that upper mold and elliptical shell are detached from, then from side to will Upper mold slotting tool is taken out, then lower die is taken off plate and is pushed up upwards (for ease of realizing that this function need to be also arranged on lower die holder and lower bolster The hole that lower die takes off plate is jacked up for piston rod) realize the disengaging of lower moulded board and elliptical shell.

The advantages of the utility model and advantageous effect are：By the setting of upper mold, then driving device action makes upper mold Push has the aluminium alloy elliptical shell of necking to form top, and the setting of plate is taken off by upper mold slotting tool and lower die and can also be facilitated Ground demoulds；It can process and meet elliptical shell aluminium section bar of the top of required precision with necking, and be not in damage by pressure The case where portion's necking；Upper die holder is driven to move downward to form necking by the action of cylinder or hydraulic cylinder, lower moulded board can Upper part of the housing is damaged by pressure to prevent upper die holder from declining too many；Lower moulded board is slidably inserted by sliding block, due to its underpart protrusion and The setting of recess can prevent its movement in process, the demoulding of upper mold after the completion of upper mold slotting tool is easy to process.
