流水槽鋼模具設(shè)計(jì)結(jié)構(gòu)要素 保定水泥U型槽模具廠 玉達(dá)

The structural elements to be considered in plastic mold designare:
①分型面，即模具閉合時(shí)凹模與凸模相互配合的接觸表面。它的位置和形式的選定，受制品形狀及外觀、壁厚、成型方法、后加工工藝、模具類型與結(jié)構(gòu)、脫模方法及成型機(jī)結(jié)構(gòu)等因素的影響。
① parting surface, i.e. the contact surface where the concave dieand the convex die fit each other when the die is closed. Theselection of its position and form is affected by the shape andappearance of the product, wall thickness, forming method,post-processing technology, mold type and structure, demouldingmethod and forming machine structure and other factors.
②結(jié)構(gòu)件，即復(fù)雜模具的滑塊、斜頂、直頂塊等。結(jié)構(gòu)件的設(shè)計(jì)非常關(guān)鍵，關(guān)系到模具的壽命、加工周期、成本、產(chǎn)品質(zhì)量等，因此設(shè)計(jì)復(fù)雜模具核心結(jié)構(gòu)對(duì)設(shè)計(jì)者的綜合能力要求較高，盡可能追求更簡(jiǎn)便、更耐用、更經(jīng)濟(jì)的設(shè)計(jì)方案。
② structural parts, i.e. slide block, inclined top, straight topblock, etc. of complex mould. The design of structural parts isvery important, which is related to the life, processing cycle,cost and product of the mold. Therefore, the design ofcomplex mold core structure requires a higher comprehensive abilityof the designer, and seeks a simpler, more durable and moreeconomic design scheme as much as possible.
③模具精度，即避卡、精定位、導(dǎo)柱、定位銷等。定位系統(tǒng)關(guān)系到制品外觀質(zhì)量，模具質(zhì)量與壽命，根據(jù)模具結(jié)構(gòu)不同，選擇不同的定位方式，定位精度控制主要依靠加工，內(nèi)模定位主要是設(shè)計(jì)者充分去考慮，設(shè)計(jì)出更加合理易調(diào)整的定位方式。
③ die accuracy, i.e. card avoidance, precise positioning, guidepost, positioning pin, etc. The positioning system is related tothe product appearance , mold and service life.According to the different mold structure, different positioningmethods are selected. The positioning accuracy control mainlydepends on the processing. The internal mold positioning is mainlyconsidered by the designer to design a more reasonable and easy toadjust positioning method.
②澆注系統(tǒng)，即由注塑機(jī)噴嘴至型腔之間的進(jìn)料通道，包括主流道、分流道、澆口和冷料穴。特別是澆口位置的選定應(yīng)有利于熔融塑料在良好流動(dòng)狀態(tài)下充滿型腔，附在制品上的固態(tài)流道和澆口冷料在開模時(shí)易于從模具內(nèi)頂出并予以清除(熱流道模除外)。
② pouring system, that is, the feeding channel from the injectionmachine nozzle to the cavity, including the main flow channel,shunt channel, gate and cold cavity. In particular, the gatelocation should be selected to facilitate the molten plastic tofill the mold cavity in a good flow state, and the solid flowchannel attached to the product and the gate cold material are easyto be ejected from the mold and removed (except for the hot flowchannel mold) when opening the mold.
③塑料收縮率以及影響制品尺寸精度的各項(xiàng)因素，如模具制造和裝配誤差、模具磨損等。此外，設(shè)計(jì)壓塑模和注塑模時(shí)，還應(yīng)考慮成型機(jī)的工藝和結(jié)構(gòu)參數(shù)的匹配。在塑料模具設(shè)計(jì)中已廣泛應(yīng)用計(jì)算機(jī)輔助設(shè)計(jì)技術(shù)。
③ plastic shrinkage and various factors affecting the dimensionalaccuracy of products, such as mold manufacturing and assemblyerrors, mold wear, etc. In addition, the matching of thetechnological and structural parameters of the molding machineshould also be considered in the design of the press mold and theinjection mold. CAD technology has been widely used in plastic molddesign.
