Injection molds are composed of which parts of the role of each?
The injection mold consists of two main parts: the moving mold and the fixed mold. Dynamic mold is active, it is installed in the injection molding machine on the moving template, fixed mold is installed in the injection molding machine on the fixed template, so it is not moving. When the injection molding machine is in operation, the moving mold will be close to the fixed mold, and they are closed to form the cavity and pouring system. When the mold is opened, the moving mold is separated from the fixed mold, and the ejector mechanism starts to move, ejecting the molded part out of the mold cavity, so as to release the molded product smoothly. Thus completing a working cycle.
1) Molding parts, which are the parts that form the mold cavity, are mainly used to determine the geometric shape and size of the plastic part, such as the convex mold determines the internal shape of the plastic part, while the concave mold determines the shape of the plastic part.
2) The pouring system, which is the channel for injecting the plastic melt into the closed mold cavity, has an important influence on the flow characteristics of the melt when filling the mold, as well as the quality of injection molding.
3) mold guiding mechanism is mainly used to ensure that the moving and fixed mold, or other parts of the mold between
Although there are many types of injection molds, but the structure of different molds is basically the same. Multi-cavity single parting surface injection mold as an example of its structural composition, as shown in Figure.
1) Forming parts this is the composition of the mold cavity parts, mainly used to determine the geometry and size of the plastic part, such as convex mold to determine the internal shape of the plastic part, while the concave mold to determine the shape of the plastic part.
2) The pouring system, which is the channel for injecting the plastic melt into the closed mold cavity, has an important influence on the flow characteristics of the melt when filling the mold, as well as the quality of injection molding.
3) Clamping guide mechanism is mainly used to ensure that the moving mold and the fixed mold, or other parts of the mold between the accurate alignment to ensure the shape and size of the plastic parts of the precision, and to avoid collision and interference of the various parts of the mold.
4) temperature control system due to the different properties of plastic, injection molding temperature requirements are different, for this reason, the need for temperature control system to regulate the temperature of the mold. The cooling of the mold generally rely on the cooling water channel opened in the mold cooling water, mold heating depends on the heating element in the mold.
5) demolding mechanism of the molded part of the unloading is done by the demolding mechanism. In Figure 4-1, the demolding mechanism is composed of push rod base plate 8 and push rod 11, push out the base plate 9 and pull the material lever 10 joint composition.
6) Parting and core pulling mechanism When the molded part has a side concave or side hole, before opening the mold to launch the molded part, it is necessary to mold the side concave or side hole of the flap module or lateral core from the molded part, and the lateral parting or lateral core pulling mechanism is a set of sideways movement mechanism in order to achieve this function.
7) Supporting parts of this kind of parts are used to install fixed or support molding parts, support parts assembled together, that is, constitute the basic skeleton of the injection mold.
8) Exhaust structure when the melt is injected into the injection mold cavity at high speed, the air in the cavity needs to be discharged, and high temperature plastics will also volatile gas, these gases need to be quickly discharged at the right time in order to avoid molding defects, injection molds for the discharge of these gases and the design of a variety of exhaust structure.
