At present, the application of molds affects any product (such as automobiles, aerospace, daily necessities, electrical communication, medical products and equipment, etc.), as long as there is a large number of products, they are made by molds. and the mold base is an integral part of the mold. Currently, the accuracy requirements of the mold base are set according to the product requirements at different levels.
What components does the mold base consist of?
How do I choose the size of the mold base?
What precautions should be taken when selecting mold bases?
The mold base consists of upper and lower mold bases, mold handles and guide devices.
The tool floor is the skeleton of the entire tool, on which all parts of the tool are attached and bear all the loads of the punching process. The upper tool seat of the mold base is connected to the press slider by the tool handle, and the lower tool seat is fixed to the working table of the press with a screw press plate.
For plastic molds: parts used to install and fix or support molded parts and other parts of the mold. Including movable and fixed mold base plates, support plates, locking screws, spacers, etc. form the basic form base.
Determination of mold base and insert size
The size of the mold mainly depends on the size and structure of the plastic product. For the mold surface, under the premise of ensuring sufficient strength, the more compact the structure, the better.
According to the external dimensions of the product (plane projection surface and height) and the product itself (e.g. construction of the side divider), the external dimensions of the mold structure can be determined. After the size of the mold base has been determined, the mold base can be roughly determined.
1. Determination of the height of the molded floor
Leave a certain clearance (5-10mm) for the height of the mold floor so that the fixing plate of the fingertip does not bump against the movable template or the movable mold carrier plate when it is fully ejected.
2. Determination of the overall structure of the mold structure
After the basic selection of the mold structure, the overall structure of the frame should be checked to determine whether the determined mold structure for the selected or not. custom injection molding machine is suitable, including size, thickness, maximum mold opening path u ejection of mold base. Method and ejection stroke, etc.
3. Selection of input material
The performance that the mold insert material should have mainly four aspects: 1. hardness; 2. Wear resistance; 3. Strength and toughness; 4. Corrosion resistance. The choice of mold insert material mainly depends on the batch and plastic category of plastic products.
Guangdong Beizhong Technology Development Co., Ltd., which has been around for more than several years, focuses on the production of mold superstructures. Here you will find the required mold bases.
