濟(jì)南注塑加工之后需要進(jìn)行模具的試模，主要作用便是測試下模具加工能不能滿足塑膠制品的要求。那么接下來我們說說試模的步驟及注意事項(xiàng)。
Ji 'nan injection molding after the need for mold testing, the main role is to test the mold processing can meet the requirements of plastic products. Then let's talk about the steps of mold testing and matters needing attention.
濟(jì)南注塑加工之試模的步驟
Ji 'nan injection molding process of mold testing steps
需要耐心調(diào)整和控制各種加工條件，避免不必要的時(shí)間浪費(fèi)和批量生產(chǎn)的麻煩，制定標(biāo)準(zhǔn)的模具測試程序，找出建立常規(guī)工作的溫度和壓力條件。清潔機(jī)筒，防止降解的橡膠或其他材料注入模具，因?yàn)榻到獾南鹉z和其他材料可能會(huì)堵塞模具，檢查機(jī)筒和模具的溫度是否適合加工原料。
Patience is required to adjust and control various processing conditions to avoid unnecessary time waste and the trouble of mass production, develop standard mold testing procedures, and find out the temperature and pressure conditions to establish routine work. Clean the barrel to prevent the injection of degraded rubber or other materials into the mold, as degraded rubber and other materials may clog the mold, and check that the barrel and mold are at the right temperature for processing the material.
尤其是模具型腔有些成品沒有完全固化的時(shí)候，在調(diào)整各種控制條件之前要慎重考慮，因?yàn)槌淠Ｂ首兓淮?，可能?huì)引起充模變化，耐心等待機(jī)器和模具的情況穩(wěn)定。這個(gè)時(shí)間可以用來檢查成品可能出現(xiàn)的問題。
Especially when some finished products of the mold cavity are not completely solidified, we should carefully consider before adjusting various control conditions, because the filling rate does not change much, it may cause the filling change, and wait patiently for the machine and the mold to be stable. This time can be used to check for possible problems with the finished product.
模具加熱時(shí)，應(yīng)適當(dāng)延長螺桿的推進(jìn)時(shí)間，以壓實(shí)成品。調(diào)試成功后，運(yùn)行少半小時(shí)穩(wěn)定，然后連續(xù)生產(chǎn)少十幾個(gè)全尺寸產(chǎn)品，標(biāo)記日期和數(shù)量，測試其實(shí)際運(yùn)行的穩(wěn)定性，根據(jù)模腔分開放置，獲得合理控制公差，測量并記錄連續(xù)樣品的重要尺寸。
When the mold is heated, the advance time of the screw should be appropriately extended to compacted the finished product. After successful commissioning, stable operation for at least half an hour, then continuous production of at least a dozen full-size products, date and quantity, test the stability of their actual operation, separate placement according to the cavity, obtain reasonable control tolerances, measure and record the important dimensions of continuous samples.

為了穩(wěn)定熔體溫度和液壓油溫度，使加工時(shí)間更長，根據(jù)所有過大或過小的成品尺寸調(diào)整機(jī)器條件。如果收縮率太大，成品看起來不夠，也可以參考加大澆口尺寸。如果型腔尺寸太大或太小，請(qǐng)修正，如果型腔尺寸仍然正確，請(qǐng)嘗試改變機(jī)器條件，檢查是否有一些型腔填充緩慢，調(diào)整填充率和模具溫度以提高其均勻性。檢查并糾正注塑機(jī)的故障，即使是的模具在維護(hù)不善的機(jī)器上也不能正常工作，檢查糾正后的樣品是否有改善，檢查所有記錄值后保留一組樣品。
In order to stabilize melt temperature and hydraulic oil temperature for longer processing time, machine conditions are adjusted according to all oversize or undersize finished products. If the shrinkage rate is too large, the finished product looks inadequate, you can also refer to increase the gate size. If the cavity size is too large or too small, correct it, if the cavity size is still correct, try changing machine conditions, check if some cavities fill slowly, adjust the filling rate and mold temperature to improve its uniformity. Check and correct malfunctions of injection molding machines, even perfect molds do not work properly on poorly maintained machines, check for improvement of corrected samples, keep one set of samples after checking all recorded values.
