Under the compression of the plunger， the melt is injected into the mold cavity through the nozzle， through the cooling channel to the mold To cool the product and remove the product after the melt has solidified. The benefits of the production of plastic products is: only one injection can get a few， or even dozens of complete products， greatly reducing the working hours， and easy to achieve automation， networking， the whole process only need a worker to operate the computer on it The In this injection mold design in the early stage of the product is the shape of the analysis， come up with three-dimensional view of the product， two-dimensional view， and the middle of the mold to build the contents of the building; medium is the design of the cavity position， Distribution， the selection of mold， the design of the gate， the choice of injection molding machine， the side of the core design. To make these parts of the two-dimensional map， three-dimensional map. The latter is the calculation of the calculation of the force on the cavity， the side of the core of the calculation of the check， the injection machine to calculate th
