EspañolThe key point of Plastic Fan Mold is the selection of the gate at the turning page. Its selection must ensure that the plastic filling pressure in the mold cavity is the same and the pouring distance is the same. At the same time, we must know whether the temperature difference at different positions of the mold will affect the degree of melting of the plastic. If the plastic melts unevenly, the weight of the wind blade will be different, and it will make a noisy sound when it rotates.
Fan blades belong to a large category of molds. When parting, the front and rear molds are inserted between the blades. Under the premise of ensuring the sealing area, the insertion angle should be as large as possible to prevent the insertion angle from being too small. Mold cooling adopts circular cooling.
There are a few things to pay attention to when designing and making Fan Blade Mold.
1) Selection of the parting line: It is recommended to extend along the middle line of the side of the blade to facilitate mold matching and avoid sharp edges.
2) Water inlet position: It is recommended to set a water inlet to each blade to prevent the unbalanced filling of the rubber.
3) The setting of the cooling water circuit: to be in place and sufficient to prevent excessive deformation of the product.
3) The processing of the internal mold: It depends on your company's equipment conditions and the selected process flow.
4) Mold assembly: pay attention to batching and exhaust.
