General plastic mold molding is composed of several basic parts
2021.05.04The specific components of the plastic mold making structure part process:
Under normal circumstances, there are two main types of plastic molds: one type is two-plate molds, commonly known as large nozzle molds; the alternative is three-plate molds, commonly known as fine nozzle molds. Regardless of whether it is a two-plate mold or a three-plate mold, a plastic mold generally consists of the following parts:
1. Mold base In plastic molds: mold base has become the most basic frame part of plastic molds. The steel quality of the mold base can guarantee the service life of a set of molds. And the stability of later production. The mold base used by Chuanghuihui Mould is customized production and procurement from the large domestic listed company "Heyuan Longji Mould Base Co., Ltd".
2. The core part of the plastic mold—cavity and core The main cavity and core of the plastic mold are commonly called mold cores or inner molds, and they are the most important part of the mold. Most of the design work is spent on the design of the mold core, and the mold core is deeply machined in the part. However, some relatively simple molds do not have a core part, and the product is formed directly on the template, especially in the early plastic molds. This structure has been gradually eliminated. There are many types of mold materials, such as imported steel and domestic national standard steel. The material selection of the brilliant mold is divided into two categories. The customer specifies the material, and the other is the orientation and the Longji company purchasing the national standard Fushun NAK80 S136 ,
3. Plastic mold auxiliary parts such as positioning ring, gate sleeve push rod (also called ejector pin or thimble), pull rod (commonly known as grab pin), support column, ejector plate guide pillar and guide sleeve, support nail (commonly known as garbage nail Etc. If it is a three-platen mold, it is often necessary to set up a special sequential mold opening control mechanism
4. Auxiliary system of Wang material mold The general plastic mold has the following three systems, namely, the pouring system, the ejection system, and the cooling system. Sometimes, because the plastic materials used need to be heated at a high temperature, some molds will also have a heating system.
5. When some plastic molds with core-pulling mechanism have holes or hooks on the side when plastic products are produced, the mold must also be equipped with one or more mechanisms for handling these holes and hook demoulding, such as sliders, inclined push rods, Hydraulic cylinders, etc. This kind of processing mechanism is called the side parting core pulling mechanism.
