30. What is opening a box?
The action of machining the position of the die core on the die blank is called frame opening.
What do you mean by 3 1. Reverse?
The method of reversing the material surface of the front and rear molds under normal circumstances is called inversion.
32. What is floating?
The method of ejecting the mold with a small insert in the place where there is local back buckle is called floating.
3 1. What do you mean by eating the front mold?
When the mold is opened, the product stays in the front mold, which is called eating the front mold.
33. What is top white?
The die force required for ejection is large, and the ejector pin is not strong enough, which causes local damage to the product. From the front of the product, there is obvious white as the top white, also called the top high nozzle.
34. What is baking?
When diving, the marks left by the water entry point on the outer surface of the point are called baking marks.

The first angle drawing method: the left view is placed on the right, the right view is placed on the left, the top view is placed below, and so on;
The third drawing method: the left view is placed on the left, the right view is placed on the right, the top view is placed on it, and so on.
53. What is the basic principle of the three views?
The basic principles of the three views are: long alignment, high alignment and equal width.
