In our surroundings, whether at home, school or office, or even anywhere on the street, we can see electrical appliances. However, electrical appliances are large and small, but they are all made by electrical appliance mould . Summer is here, we can't do without electric fans. Today we will talk about the design of electric fan molds.
There are many ways of fast coding for electric fan molds, the common ones are mechanical, hydraulic, and electromagnetic coding. Some molds use mechanical fast coding. V-grooves are designed on the fixed mold panel and the movable mold base plate. Pay attention to the width and angle tolerances. The thickness tolerance of the fixed mold panel and the movable mold base plate also needs to be controlled within 0.2. The connection between the 5 fan blades of the plastic part and the central dome is oblique, that is, the fan blades need to be twisted at an angle to connect to the dome. In this part, the front and rear mold cores need to be inserted. If the demolding angle of the sidewall of the dome is too large, the difference between the front and rear mold cores will be large here, which will affect the appearance of the plastic part. For fan blades with high appearance requirements, the demolding angle of the outer side of the dome sidewall can be as small as 0.25º. The combined plastic part material is PP, and the small demolding slope will not affect the demolding of the plastic part.
Some plastic chair injection mould will also be made in this way. swymould.com
