刘青平 due to deep molding product 越 越 more, application 越 越广泛, deep molding has its property and 规律, according to deep product molding principle, combined specific as 实践, below/following several 方面 看 method: 一, deep product molding analysis 1, plastics raw materials deep molding, its runner ratio positive 常情况 lower long more, this requirements plastics raw materials tool has relatively low viscosity and good flow property and relatively good heat stabilized property. （ in thin product molding 方面, this 显 尤 is important. ）2, machine deep product, most basic front is: high injection pressure; large injection speed rate. this conditions also made type injection molding parts machine can deep product. need solution this issues, can from 三 方面想办 method: is increase large recycled; is 油路; is increase can plant/unit. meanwhile, deep product requirements machine has relatively large mold opening and relatively large 移模行程. 3, injection molding parts mold due to deep product type relatively long, add upper molding pressure large, type force function easy generate bending deformation or type solid good easy generate 松动, injection molding parts mold appearance quality and inner in quality excellent poor effect/influence to deep product molding. appearance quality is injection molding parts mold type surface and surface coarse degree, it effect/influence material flow, light degree 差势必 make injection pressure rise high; inner in quality is injection molding parts mold selection material and injection molding parts mold rigid degree; demolding and gas is injection molding parts mold inner in quality 两 方面; gate selection and mold temperature control is deep injection molding parts mold overlook important factors. 二, injection molding parts molding and injection pressure made formed in deep product molding 方面, injection pressure made molding method can separation injection molding parts molding method, this main/primary is front ratio rear more has advantages. 三, deep product molding property deep product molding, to very more 方面 限 made, plastics raw materials, injection molding parts mold, made as process and other. meanwhile, machine 本身亦会受 to made, this is is: 1, in deep product molding technology also is very formed 熟, very stability, this 直接反映 in injection molding parts mold design, made as and processing process water upper. technology development, add upper for deep molding product 进一步 understanding and 认识, this issues very fast to solution. 2, due to inner currently production injection molding parts machine basic upper also is machine machine is 主, is this type of machine to 两 方面 conditions made 约, sheet/plate 行程, most large in types type machine upper can can more. need more this parameters, 唯一 办 method is use large specifications machine. this machine its it parameters versus increase large, machine can consumption increase large, machine price 也会跟 improve/increase, but also injection molding parts mold force large easy deformation, but also injection molding parts mold small, injection molding parts mold force good easy fracture, another if 两边连杆（铰边）不 and other long or injection molding parts mold balanced formed 不均衡, force 时, sheet/plate balanced type 芯倾斜, 也会引致壁 thick 不均. 3, use liquid pressure machine substitute/replace machine machine deep product, 应当说 good more, 但传统 liquid pressure machine 普遍存 in 启, speed degree slow, rise pressure time long disadvantages. if solution this several issues, liquid pressure machine in deep molding product advantages will 会显露出. 四, solutions although currently in deep product molding also to many conditions made 约, 但克服 this factors method very more. 首先, is solution plastics raw materials issues. this issues in already to solution. its is injection molding parts mold design, manufacturing and product made as process issues, this type of deep injection molding parts mold, selection strong/high degree high, wear resistant, corrosion resistant material made as. mold temperature control, gate selection, gas add 以考虑. injection molding parts mold separation type can design in different upper, ejection, demolding can 顶针杆 and injection molding parts mold type versus 连接, its need heavy type strong/high degree, type 芯模. most rear is solution machine issues. in this 里, toward large recommendation company made production 四缸直锁二 sheet/plate injection molding parts machine. （如图示） this type of machine most large features is: 1, clamping degree high, force 均衡. 2, clamping long, mold opening force large, also can according to use requirements add long. 3, rise pressure time short, clamping speed degree fast, impact, phenomenon. 4, liquid pressure system simple, as repair 方便. 5, use 调模, use lubricated, abrasion loss. 6, system force short, system rigid degree strong/high. 7, low pressure can 靠, can consumption less. due to above features, this type of machine especially combined deep product. 四缸直锁二 sheet/plate injection molding parts machine 问世几 year, its technology water day 趋完善, in very more is machine machine, liquid pressure machine can ratio 拟, this in very more injection molding parts processing 家, in outer that already to separation can, 并显示出 its for advantages. 广东泓利 machine has company
