Abstract
The invention discloses a rounding die of an LED lampshade. The rounding die of the LED lampshade comprises an upper die and a lower die; the upper die comprises an upper bearing plate, an upper plate, an upper cushion plate and an upper die plate which are fixedly connected from top to bottom in sequence; the lower die comprises a lower bearing plate, a lower die seat, a lower cushion plate and a lower die plate which are fixedly connected from bottom to top in sequence; guide columns are arranged in the middle parts of the upper plate, the upper cushion plate, the stopping plate and the upper die plate; assistant guide columns are arranged in the inner centers of the guide columns; the top end of each assistant guide column extends to the middle part of the upper bearing plate, and while the bottom end of each assistant guide column is equipped with an ejecting pin; nitrogen springs are arranged in the middle parts of the lower cushion plate and the lower die plate; springs are arranged at both sides of the nitrogen springs; a positioning block is mounted on each spring; the top end of each positioning block extends to the outer part of the lower die plate; a lower block is arranged between the lower die seat and the lower bearing plate; sliding blocks which are positioned at two sides of a product are arranged on the surface of the lower die plate. According to the rounding die for the LED lampshade, the operation and use are convenient, a film can be molded once during being pressed, and therefore, the working efficiency is greatly raised; meanwhile, the product can be firmly fixed; when pressing the film, the product is positioned between the two positioning blocks, so that the rounding accuracy can be ensured.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of LED lamp cover rounding die.
Background technology
Blank is made to become the instrument of the product having given shape and size under external force.Be widely used in stamping-out, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting, and in the compression moulding of goods such as engineering plastics, rubber, pottery or the formed machining of injection moulding.Mould has specific profile or cavity shape, and the contour shape that application has cutting edge can make blank be separated (stamping-out) by outline line shape.Application cavity shape can make blank obtain corresponding three-dimensional shape.Mould generally comprises dynamic model and cover half (or punch and die) two parts, the two partable.Take out product time separately, make blank inject mold cavity when closing up and be shaped.Mould is precision instrument, complex-shaped, bears the expansive force of blank, all has higher requirements to structural strength, rigidity, case hardness, surface roughness and machining accuracy, and the development level that mould is produced is one of important symbol of machine-building level.
In prior art, easily to occur that product coordinates between patrix counterdie when full circle in the course of the work close for lampshade rounding die, and cause the undesirable and regulation of product, product can not be positioned, easily occur deviation in the fabrication process, precision is low simultaneously.
Therefore, for solving the problem, spy provides a kind of new technical scheme to satisfy the demands.
Summary of the invention
The invention provides a kind of LED lamp cover rounding die.
The technical solution used in the present invention is:
A kind of LED lamp cover rounding die, comprise upper die and lower die, described patrix from top to bottom comprise be fixedly connected sequentially mounting plate, upper plate, upper padding plate, only plate and cope match-plate pattern, described counterdie comprises the bottom plate, die shoe, lower bolster and the lower bolster that are fixedly connected sequentially from the bottom to top
Be provided with guide pillar in the middle part of described upper plate, upper padding plate, only plate and cope match-plate pattern, described guide pillar inner hub location is provided with auxiliary guide column, and this auxiliary guide column top extends in the middle part of mounting plate, and bottom is provided with jigger pin,
Nitrogen spring is provided with in the middle part of described lower bolster and lower bolster, spring is equipped with in nitrogen spring both sides, each spring is all provided with locating piece, described locating piece top extends to lower bolster outside, described nitrogen spring top is provided with dowel pin with tooth, be provided with lower piece between described die shoe and bottom plate, described lower bolster surface is provided with slide block, and slide block is positioned at product both sides.
Further, all fixed by hex bolts with stopping on the left of plate and cope match-plate pattern on the left of described upper plate and upper padding plate.
Further, be provided with bolt near nitrogen spring both sides, and by this bolt, lower bolster and lower bolster fixed.
The invention has the beneficial effects as follows: easy for operation, press mold one-shot forming, substantially increases operating efficiency, and simultaneously by product fixation, when press mold, product, between two pieces of locating pieces, can guarantee the accuracy of full circle.
