摘 要:通過對鋼球周轉箱的材料、結構、質量要求、生產量分析，確定了合理的模具結構方案，分析了模具分型面、型腔數(shù)量及布置、澆注系統(tǒng)、排氣方式、冷卻系統(tǒng)，設計出型腔模、抽芯機構和脫模機構。加工組裝模具后，選擇合適的注射機，進行了生產驗證，達到產品質量要求。 分析了鋼球周轉箱塑件的結構特點，敘述了該塑件成型工藝、注射模的結構和工作原理，其原理是：用斜導柱外側抽芯,型芯頂出零件,進料時采用點澆口進 料形式,當開模的時候,用拉料桿把澆注系統(tǒng)凝料頂出,然后利用型芯內推管推出塑件,合模時用彈簧先復位,然后進行下一次成型開始。提高了生產效率。 關鍵詞：注射模 ； 斜導柱 ； 側抽芯 ； 型芯
ABSTRACT:Analyse the Gangqiu turnover box, configuration, quality, output of the enzyme box cover, choose the suitability mold plan, analyse the parting line, impression quantity and place in mold, gating system, vent gas type, cooling system, design cavity plate, angle pin side action, mould emptier,and so on. machining & assembling mold, choose the injection molding machine, do production test, it is to meet quality of the enzyme box cover. it is usefulness for stylist when design the alike product. Analyzed the structure characteristics of the perfume cover outer shell plastics piece， described the piece’s structure and work principle which model a craft and inject a mold， its principle ：adopt and certainly be apart from bolt and spring coil and carry on two cents type， use inclined lead a side outside the pillar and take out heart， type the heart crest spare parts， while entering and anticipating adoption incubate the type sprinkle into anticipate a form， while opening a mold， with the ball head pull and anticipate a pole sprinkle and note system and anticipate， then make use of and take out and push plank and release a plastics piece inside a heart，use spring coil and reset first while matching a mold， then carry on willing model a beginning next time.Raised to produce an efficiency. Keyword：inject a mold； inclined to lead pillar；the side takes out heart；type heart |
