The design uses basic knowledge of plastic mold art.and mold designing.At first ,we analyze the products performance.and select the proper material and then design the mold cavity and it’s distribution.three dimension molding to choose the proper mold joint.At last,analyze the character of the product.In order to identify the design,data is the key point of the design and the equipment of the products. The design use the construction of exactly eight cavity,these are the principle,first,we send the inattentive particulate matter and powder matter to the high heat machine hopper to heat,melt,and make them into dissolve matter,and then under the high pressure of plunger and screw,they go in a quick speed,through the melting jet in the head of the machine shotting the lower closed model.After the pressure of dynamic fixed clamping becomes cold.We can withdraw the fashioned binding post. Following are the processes:the shot machine send the materials to the melting stoves. Passing by the primary and the secondary roads.Filling with the mold and after the cold pressure ,they separated.The side core-pulling began to work.When it comes to an end,the pressure machine push the knockout plate,and then,withdraw it with your hand.
