注塑模具加工驱动的几种方式

来源:/ 日期:2018-08-11

 
注塑模具加工运动的驱动和驱动力(冲压力,模具的锁模力,材料的落锤重,挤压力等)是由成形加工机床和设备的动力经传动机构提供的。
    The driving force and driving force (impact force, die locking force, material drop weight, extrusion force, etc.) of the injection mold processing movement are provided by the power of the forming machine tool and equipment through the transmission mechanism.
    机电驱动:如冲压机、摩擦压力机、辊锻机械等,都是由电动机提供动力和旋转运动,以驱动传动机构,并通过滑块等和模具运动部分进行连接运动,以驱动模具定向运动,并把传递的驱动力作用于模具,使模具对材料进行成形加工。
    Mechanical and electrical drive: such as punching press, friction press, roll forging machinery, etc., are powered and rotated by the motor to drive the transmission mechanism, and connected with the moving part of the die through the slider, etc., so as to drive the directional movement of the die, and use the transmitted driving force for the die to make the die process the material.

    电液驱动:即通过注塑成型电动机驱动液压泵或水泵产生液压和水压,并经过液体的液压输送和控制系统,产生一定的额定压力来驱动模具的运动部分(如动模)相连接的液压缸或者活塞,驱使动模相对定模来进行定向平移的运动,再对材料进行进一步压缩,使材料在进行成形加工后成为制件
    Electro hydraulic drive: through the injection molding motor to drive the hydraulic pump or water pump to generate hydraulic pressure and water pressure, and through the hydraulic transmission and control system of the liquid, generate a certain rated pressure to drive the hydraulic cylinder or piston connected with the moving part of the mold (such as the moving mold), drive the moving mold to move in a directional direction relative to the fixed mold, and then further compress the material, The material becomes a part after forming
    气压成形;主要用于吸塑和吹塑成形加工,即当模具处于固定状态的时候,经气泵使其产生一定的负压将塑料板材直接吸贴于模具型面上,形成制件,吹塑则是通过气泵产生一定气压的气体,吹人热熔态塑件或热熔态玻璃制件毛坯空腔,使其扩展、变形,并贴附在模具型腔表面上,形成制件。
    Air pressure forming; It is mainly used for blister and blow molding, that is, when the mold is in a fixed state, a certain negative pressure is generated by the air pump, and the plastic sheet is directly sucked onto the mold surface to form parts. Blow molding is to generate a certain pressure of gas through the air pump, and blow into the blank cavity of hot-melt plastic parts or hot-melt glass parts to expand and deform them, And attached to the surface of the mold cavity to form parts.
    另外,注塑模具加工驱动比方说铝合金的型材,塑料型材、片材或薄膜,一般都采用挤出成形的工艺。其模具固定在机头上,材料以挤压形式通过模具,对模具作相对运动而成的各种制件。如塑料型材是依靠不停的挤出机器的螺杆的螺旋运动,将塑料挤入模具并通过模具的型面,经冷却定型成型材。挤出的型材被牵引机构向前牵引,使进行连续成形加工。
    In addition, the injection mold processing drive, such as aluminum alloy profiles, plastic profiles, sheets or films, generally use extrusion process. The die is fixed on the head of the machine, and the material passes through the die in the form of extrusion to make relative movement to the die. For example, the plastic profile depends on the continuous spiral movement of the screw of the extrusion machine to extrude the plastic into the mold and pass through the mold surface, and then the plastic is shaped by cooling. The extruded profile is pulled forward by the traction mechanism to make continuous forming.
