本发明的工作过程为: Working process of the present invention is:
第一步:将模具吊装在注塑机的四支导柱间,模具上的定位圈对准注塑机定位孔,然后通过压板将定模座板(模具定模部分)连接在注塑机的固定工作台面上;通过压板将动模座板(模具动模部分)连接在注塑机的移动工作台面上; The first step: hoist the mold between the four guide pillars of the injection molding machine, align the positioning ring on the mold with the positioning hole of the injection molding machine, and then connect the fixed mold seat plate (the fixed mold part of the mold) to the fixed work of the injection molding machine through the pressure plate On the table; connect the movable mold seat plate (the movable mold part of the mold) to the mobile working table of the injection molding machine through the pressure plate;
第二步:调模,即将注塑机开合行程调整到适合模具总厚度范围内,由注塑机将模具压紧,保证模具开合顺利; The second step: mold adjustment, that is, adjust the opening and closing stroke of the injection molding machine to the range suitable for the total thickness of the mold, and press the mold tightly by the injection molding machine to ensure the smooth opening and closing of the mold;
第三步:模具合模后,注塑机将熔融状态塑料通过浇口套,采用多个进浇口的方式浇入模具型腔,接着冷却30秒,让塑料充分固化成型,开模。开模时,注塑机开合模系统带动动模部分后退;动模部分与定模板开始分离,移动到一定距离,动模板Ⅰ5在限位板31作用下被限位,停止移动;同时,顶出机构即顶针25、拉料针26、复位杆27、顶针板15和顶针固定板14在限位块29作用下停止移动;动模板Ⅱ8继续移动,动模镶针Ⅰ16、动模镶针Ⅱ24从产品中脱出;动模板Ⅱ8移动到一定距离,在限位螺钉17的作用下,动模板Ⅱ8停止移动;注塑机的顶棍使顶针固定板14、顶针板15移动,带动拉料针26、顶针25向定模方向移动,从而使产品和料头从动模镶件6上脱掉,至此完成一次成型过程。 Step 3: After the mold is closed, the injection molding machine pours the molten plastic into the mold cavity through multiple gates through the sprue sleeve, and then cools for 30 seconds to allow the plastic to fully solidify and form, and the mold is opened. When the mold is opened, the mold opening and closing system of the injection molding machine drives the movable mold part back; the movable mold part starts to separate from the fixed template and moves to a certain distance, and the movable template I5 is limited by the limit plate 31 and stops moving; at the same time, the top The ejection mechanism, that is, the thimble 25, the pulling needle 26, the reset lever 27, the thimble plate 15 and the thimble fixed plate 14 stop moving under the action of the limit block 29; the movable template II8 continues to move, the movable mold inserts I16, the movable mold inserts II24 out of the product; the movable template Ⅱ8 moves to a certain distance, and under the action of the limit screw 17, the movable template Ⅱ8 stops moving; the ejector stick of the injection molding machine moves the thimble fixed plate 14 and the thimble plate 15, driving the pulling needle 26, The thimble 25 moves towards the fixed mold direction, so that the product and the material head are taken off from the movable mold insert 6, and a molding process is completed so far.
