15-year precision mould making

   All kinds of plastic mold parts structure,first,the structure of plastic mold parts is mainly composed of a fixed template and template composition, characteristic is just one type of injection molding can be in after the completion of all the plastic mold parts process. Second, plastic mold parts is based on the two plate injection mold is added a movable template, is also in the injection molding must through two types to complete the release action. The structure of plastic mold parts,  injection system, the top out of the system, the core pulling system, cooling system, exhaust system, composed of reset and reset mechanism.  Plastic mold parts, the forming parts to obtain the desired shape and size. Including static and dynamic model of bile, core molding parts. Molding process injection mold of the same part can have a variety of forms, but must choose good forming performance as the premise, and fully consider the condition of the existing equipment technology is strong, has the advantages of simple manufacture, easy to ensure accuracy, low manufacturing cost.  Plastic mold parts system: the plastic melt filled to the smooth and orderly in the cavity, and the pressure is transmitted to all parts of the filling process and solidification process, close to obtain tissue, clear appearance parts. Casting system consists of the sprue, runner, cold well, pulling rod and the gate. Center line main runner is generally located in the mold, diameter size affects its plastic mold parts drop, flow rate and filling time. Shunting with allocation and buffer action from the main flow channel for plastic.

    Mainly used for the storage of intermittent cold material during injection, the front end of the nozzle by the radiation temperature caused by the resulting from the decrease. If they enter the channel, will plug flow and reduce the material flow rate; into the cavity, the WIP on cold material, at the same time in the mold, cold well and plays the cold material main channel from the sprue sleeve out of the shunting effect and fixed in the die. Often used in conjunction with the pulling rod and the thimble. Often used in conjunction with the pulling rod and the thimble. Pulling rod is used to make the passage in need side, often have type pulling rod and the ball head pulling rod. The gate is the connection between the sprue and runner and cavity, the terminal is also pouring system.The gate is the connection between the sprue and runner and cavity, the terminal is also pouring system. The gate for the flow control of plastic, so that in an ideal fluid into the cavity plays a decisive role in. The position and shape of the gate, the size of the design is correct or not will directly determine the product quality effect of injection and injection efficiency. The position and shape of the gate, the size of the design is correct or not will directly determine the product quality effect of injection and injection efficiency. Gate forms are common sprue. Disk gate. Spoke gate. Gate ring. The pin point gate. Latent gate. The side gate. Fan gate. Sewing gate tab gate and so on.
