按鍵零件的模具設(shè)計(jì)
摘 要
本設(shè)計(jì)的題目是按鍵零件的塑料注塑模設(shè)計(jì),從圖紙上分析,該零件總體形狀為長(zhǎng)方形。在長(zhǎng)度方向上有3個(gè)矩形的異形孔,易成型。從壁厚上看,壁厚最大處為1.5mm 最小處為1.2mm 壁厚較均勻,有利于零件的成型。
根據(jù)塑件的特點(diǎn),模具型芯在動(dòng)模部分。開(kāi)模后,塑件應(yīng)收縮包緊型芯,而
留在動(dòng)模部分,其推出機(jī)構(gòu)采用推件板推出的推件方式。該種脫模方式是在分型面處從殼體塑件的周邊推出。推出力大且均勻。對(duì)側(cè)壁脫模阻力較大的薄壁箱體或圓筒制品,推出后外觀上不留痕跡。
對(duì)合導(dǎo)向機(jī)構(gòu)的功能三保證動(dòng)定模部分能夠準(zhǔn)確對(duì)合,使分別加工在動(dòng)模和定模上的成型表面在模具閉合后形成形狀和尺寸準(zhǔn)確的腔體,從而保證塑件形狀,壁厚和尺寸的準(zhǔn)確,該模具采用導(dǎo)柱對(duì)合導(dǎo)向機(jī)構(gòu)。導(dǎo)柱和型芯一起安裝在動(dòng)模一側(cè),這樣在合模時(shí)可起保護(hù)作用。
相信不久本模具投入市場(chǎng)一定能帶來(lái)很好的效益服務(wù)大眾,服務(wù)社會(huì)。

Pressed key components mold design
This design topic is the pressed key components plastic note molds the design, analyzes from the blueprint, this components overall shape is a rectangle. Has 3 rectangular in the length direction the different shape holes, is easy to take shape. Looked from wall thickness that, the wall thickness most main point is the 1.5mm most narrow view is the 1.2mm wall thickness is even, is advantageous to components taking shape.
According to models a characteristic, the mold core is moving the mold to be partial. After operates the mold, models to be supposed to contract male ,but
Remains moves the mold to be partial, it promotes the organization to use pushes a board to promote pushes a way. This drawing of patterns way is peripheral models in a minute profile place from the shell to promote. Promotes the strength big also is even. To the sidewall drawing of patterns resistance big thin wall box body or the cylinder product, after promotes seemingly not the scar.
The involution guidance organization function three guarantees moves decides the mold to be partial can the accurate involution, causes to process separately in moves the mold and decides on the mold to take shape the surface closed to form the shape and the size accurate cavity body after the mold, thus guaranteed models a shape, wall thickness and size accurate, this mold uses the guide pillar involution guidance organization. The guide pillar and the core installs together in moves a mold side, like this when gathers the mold may get up the protective function.
Believed this mold invests the market certainly to be able soon to bring the very good benefit service populace, the service society.
