1. Selection of demoulding mechanism:

脫模機構的驅動主要有兩種，即氣缸驅動或油缸驅動，為便于成型機各機構的有益配合，擬定采用油缸驅動。

There are two main types of demoulding mechanism driving, namely cylinder driving or oil cylinder driving. In order to facilitate the beneficial cooperation of various mechanisms of molding machine, it is proposed to adopt cylinder drive.

2、上料機構：

2. Feeding mechanism:

上料機構主要有兩種形式：

There are two main types of feeding mechanism

(1)稱重式上料機構：

(1) Weighing feeding mechanism:

稱重式上料機構是取定一定重量的物料喂到模具中，其優點是可以獲得準確的上料量，缺點是需要一套復雜的機械電子機構，因而增加機構的造價。

The weighing feeding mechanism is to take a certain weight of material and feed it into the mold. Its advantage is that it can obtain accurate feeding amount, but the disadvantage is that it needs a set of complex mechanical and electronic mechanisms, so it increases the cost of the mechanism.

(2)定容式上料機構：

(2) Constant volume feeding mechanism:

定容式上料機構是取定一定容積的物料喂到模具中，其的優點是機構簡單、造價廉，缺點是較難得到準確的上料量。

The constant volume feeding mechanism is to take a certain volume of material and feed it into the mold. Its advantages are simple mechanism and low cost, but the disadvantage is that it is difficult to get accurate feeding amount.

中盤所需要的原料不是相當準確，允許有一定的誤差，故擬定采用定容式上料機構。

The raw material needed by the middle plate is not quite accurate, and there is a certain error allowed, so the fixed volume feeding mechanism is proposed.

3、攤料機構：

3. Spreading mechanism:

一次性餐具模具推料機構的作用是利用上模的旋轉，在加壓之前將料推開，以保障壁厚均勻，擬采用液壓馬達驅動方式。

The function of pushing mechanism of disposable tableware mold is to use the rotation of upper mold to push the material away before pressurization, so as to ensure uniform wall thickness. It is planned to adopt hydraulic motor driving mode.

4、回轉機構：

4. Rotary mechanism:

轉機構的作用是轉換工位，主要有以下幾種方式：

The function of the rotating mechanism is to change the station, mainly in the following ways:

(1)輪槽間歇機構：

(1) Groove intermittent mechanism:

此種方式優點是結構簡單，但有沖擊、加工精度高，只適合功率的較小的場合

The advantages of this method are simple structure, but impact, high machining accuracy, only suitable for small power occasions

(2)棘輪棘爪間歇機構：

(2) Intermittent mechanism of ratchet and pawl:

棘輪棘爪間歇機構是一種常見的傳動機構，缺點是噪音大，大多用在輔助機構

Ratchet and pawl intermittent mechanism is a common transmission mechanism, which has the disadvantage of high noise and is mostly used in auxiliary mechanism

(3)齒輪-齒圈傳動：

(3) Gear ring gear drive:

齒輪-齒圈傳動是工程機械中常用的驅動方式，技術成熟，但是造價比較高。

Gear ring gear transmission is a commonly used driving mode in construction machinery, with mature technology but high cost.

(4)齒輪-銷齒傳動：

(4) Gear pin tooth drive:

齒輪-銷齒傳動是齒輪-驅動的變種，由于銷輪的輪齒是圓銷，與一般齒輪相比，具有結構簡單、加工方便、造價底、拆修方便等優點，故以其代替尺寸較大的漸開線齒輪時，有較大的優良性。比較齒輪-齒圈傳動越加適合在成型機上使用。

Gear pin gear transmission is a variation of gear drive. Compared with general gears, pin gear transmission has the advantages of simple structure, convenient processing, low cost and convenient disassembly and repair. Therefore, it has great advantages when replacing involute gear with larger size. The gear ring gear transmission is more suitable for use in molding machine.
