  成型机构是新蒲京32450com玉米淀粉餐具模具中的主要机构,在某些方面决定了产品的性能,因此成型机构的选择非常重要。以下为该装置各部件的形状选择分析:

  Forming mechanism is the main mechanism of disposable corn starch tableware mold, which determines the product performance in some aspects, so the selection of forming mechanism is very important. The following is the shape selection analysis of each part of the device:
  1. 脱模机构的选择:
  1. Selection of demoulding mechanism:
  主要有两种驱动机构,即气缸驱动或气缸驱动,为了方便成型机各机构的有益合作,建议采用气缸驱动。
  There are mainly two kinds of driving mechanisms, namely cylinder driving or cylinder driving. In order to facilitate the beneficial cooperation of various mechanisms of the molding machine, it is recommended to use cylinder driving.
  2. 加煤机构:
  2. Coal feeding mechanism:
  送料机构主要有两种类型:
新蒲京32450com玉米淀粉餐具
  There are two main types of feeding mechanism:
  (1)称重送料机构:
  (1) Weighing and feeding mechanism:
  称重送料机构是将一定重量的材料送入模具,其优点是可以获得准确的送料量,缺点是需要复杂的机械和电子机构,从而增加了机构的成本。
  Weighing and feeding mechanism is to send a certain weight of materials into the mold. Its advantage is that it can obtain accurate feeding amount, but its disadvantage is that it needs complex mechanical and electronic mechanisms, thus increasing the cost of the mechanism.
  (2)定容进给机构:
  (2) Constant volume feeding mechanism:
  恒容送料机构是将一定量的材料送入模具,其优点是简单,成本低,缺点是更难得到准确的送料量。
  Constant volume feeding mechanism is to send a certain amount of materials into the mold, which has the advantages of simplicity, low cost and more difficult to get accurate feeding amount.
  由于介质板所需要的材料并不十分准确,允许存在一定的误差,因此提出了定容送料机构。
  Because the material needed for the medium plate is not very accurate and some errors are allowed, a constant volume feeding mechanism is proposed.
  3.材料共享机制:
  3. Material sharing mechanism:
  新蒲京32450网站推模机构的功能是在加压前,利用上模具的旋转将物料推离,保证壁厚均匀。提出采用液压马达驱动方式。
  The function of pushing die mechanism of disposable tableware is to push materials away by using the rotation of upper die before pressurization, so as to ensure uniform wall thickness. The hydraulic motor driving mode is proposed.
  4. 回转机构:
  4. Slewing mechanism:
  输送机构的作用是输送站,主要有以下几种方式:
  The function of the conveying mechanism is the conveying station, mainly in the following ways:
  (1)轮槽间歇机构:
  (1) Wheel groove intermittent mechanism:
  该方法具有结构简单、冲击大、加工精度高、只适用于小功率场合的优点
  This method has the advantages of simple structure, large impact, high machining accuracy and is only suitable for small power occasions
  (2)棘轮棘爪间歇机构:
  (2) Intermittent mechanism of ratchet and pawl:
  棘轮棘爪间歇机构是一种常见的传动机构
  The intermittent mechanism of ratchet and pawl is a common driving mechanism
  (3)齿轮和齿环传动:
  (3) Gear and ring gear drive:
  齿环传动是工程机械中常用的传动方式。
  Gear ring transmission is a common transmission method in construction machinery.
  (4)小齿轮和销齿轮传动:
  (4) Pinion and pin gear drive:
  齿轮-销齿传动是各种齿轮驱动,因为销轮牙是一个圆形销,与一般的装置相比,结构简单,加工容易,成本,容易维修和其他的优势,所以它是用来代替渐开线齿轮的尺寸大一点,有一个更大的好。齿轮-齿轮环传动比较适合在注塑机上使用。
  Gear pin gear drive is a kind of gear drive, because the pin gear tooth is a round pin, compared with the general device, it has the advantages of simple structure, easy processing, cost, easy maintenance and other advantages, so it is used to replace the involute gear with a larger size and a better one. Gear ring transmission is suitable for injection molding machine.
  通过对上述方案的比较,确定新蒲京32450com玉米淀粉餐具模具的旋转机构采用齿轮-销齿传动。
  Through the comparison of the above schemes, it is determined that the rotation mechanism of the disposable corn starch tableware mould is driven by gear pin teeth.
