1. Inspection of mold opening and closing under low pressure

模具分快、中、慢各3次開合，在開合過程中有無異常聲響，有無阻滯現象；

The mold shall be opened and closed three times for fast, medium and slow respectively, and whether there is abnormal sound and blocking during the opening and closing process;

模具開合動作順暢，有無干涉發生。

The opening and closing action of the die is smooth without interference.

2. 模具頂出系統的檢查（低壓下）

2. Inspection of mold ejection system (under low pressure)

頂出動作分快、中、慢各頂出3次，檢查有無異?，F象；

The ejection action is divided into fast, medium and slow ejection for 3 times respectively, and check whether there is any abnormality;

平面處的頂針（司筒）頂出后，是否會發生松脫或卡死；

Whether the thimble (cylinder) at the plane will be loosened or stuck after being ejected;

斜面頂針或司筒裝置，是否加定位銷(防止松動或轉動）；

Whether the inclined thimble or cylinder device is equipped with positioning pin (to prevent loosening or rotation);

頂出系統（頂針或頂塊）頂出時是否有異常響聲以及振顫。

Whether there is abnormal sound and vibration when the ejector system (ejector pin or ejector block) is ejected.

3. 模具復位的檢查

3. Inspection of mold reset

模具分快、中、慢速度各復位3次，觀看是否能回到位（復位）；

The mold is reset 3 times at fast, medium and slow speeds respectively to see whether it can return to the position (reset);

復位后，斜頂針端面不高于模芯0.1mm或與模芯平齊；

After reset, the end face of the oblique thimble shall not be higher than 0.1mm or flush with the mold core;

復位用限位咭掣接觸是否良好；

Whether the reset limit card is in good contact;

頂針頂出時是否與行位的動作發生干涉（滑塊是否回到位）；

Whether the ejector pin interferes with the action of the row position (whether the slider returns to the position);

模具是否裝有頂針復位裝置（機械式）。

Whether the die is equipped with thimble reset device (Mechanical).

4. 行位（滑塊）動作的檢查

4. Inspection of line position (slider) action

模具按快、中、慢各3次開合模，觀察行位動作是否順暢；

The mold shall be opened and closed three times for fast, medium and slow respectively, and observe whether the movement of the row position is smooth;

行位回位是否正常，與頂針是否發生干涉；

Whether the line return is normal and whether it interferes with the thimble;

行位定位是否牢靠；

Whether the row position positioning is firm;

液壓抽芯裝置動作順序先后情況；

Action sequence of hydraulic core pulling device;

行位在空運行中有無拉傷、“卡死”現象。

Whether the line position is pulled or stuck during empty operation.
