化妝品塑料模具，是塑料加工工業(yè)中和塑料成型機配套，賦予塑料制品以完整構型和精確尺寸的工具。按照成型方法的不同，可以劃分為不同的模具種類(lèi)。

模具，工業(yè)生產(chǎn)上用以注塑、吹塑、擠出、壓鑄或鍛壓成型、冶煉、沖壓等方法得到所需產(chǎn)品的各種模子和工具。簡(jiǎn)而言之，模具是用來(lái)制作成型物品的工具，這種工具由各種零件構成，不同的模具由不同的零件構成。它主要通過(guò)所成型材料物理狀態(tài)的改變來(lái)實(shí)現物品外形的加工。

01 Injection Mold

It is mainly thermoplastic products in the production of the most common application of a molding mold, injection mold corresponding to the processing equipment is the injection molding machine, the plastic is first in the bottom of the injection molding machine heated cylinder by the heat of the melt, and then in the injection molding machine under the impetus of the screw or plunger, the injection molding machine through the nozzle and the mold of the injection molding machine pouring system into the mold cavity, the plastic cooled and hardened to shape, molding to get the product.

Its structure usually consists of molding parts, pouring system, guiding parts, launching mechanism, temperature adjustment system, exhaust system, support parts and other parts, manufacturing using cosmetic plastic mold steel. Injection molding processing method is usually only applicable to the production of thermoplastic products, with injection molding process to produce a wide range of plastic products, from daily necessities to all kinds of complex electrical appliances, automotive parts and so on are molded with injection mold, it is the production of plastic products in the production of the most widely used a processing method.

02 Blow Mold

Used to mold plastic containers hollow products (such as beverage bottles, daily necessities and other packaging containers) of a mold, blow molding form according to the principle of the process is mainly extrusion blow molding hollow molding, injection molding form according to the principle of the process is mainly extrusion blow molding hollow molding, injection blow molding hollow molding, injection extension blow molding hollow molding (commonly known as the injection of the pull blowing), multi-layer blow molding hollow molding, sheet blow molding hollow molding and so on. Blow Molding

Blow molding of hollow products corresponding to the equipment is usually called plastic blow molding machine, blow molding is only applicable to the production of thermoplastic varieties of products. The structure of the blow mold is relatively simple, the material used is mostly made of carbon.

03 Extrusion Dies

A class of molds used for molding and producing continuous shaped plastic products, also called extrusion molding heads, are widely used in the processing of pipes, rods, monofilaments, plates, films, wire and cable coverings, profiles and so on.

Its corresponding production equipment is the plastic extruder, the principle is solid plastic in the heating and extruder screw rotation under pressure conditions melt, plasticize, through a specific shape of the mouth of the die and made of cross-section and the shape of the mouth of the die with the same shape of the continuous plastic products. Its manufacturing materials are mainly carbon structural steel, alloy tooling, etc. Some extrusion molds in need of wear-resistant parts will also be inlaid with diamond and other wear-resistant materials.

The extrusion process is usually only applicable to the production of thermoplastic products, which are structurally distinct from injection molds and compression molds.

04 Blister Mould

Plastic plates, sheets as raw materials for molding some of the simpler plastic products of a mold, the principle is the use of vacuum bloom method or compressed air molding method to make the fixed in the concave mold or convex mold plastic plates, sheets, in the case of heating and softening of the deformation of the paste in the mold cavity to get the required molded products, mainly used in the production of some daily necessities, food, toys, packaging products.

Blister mold for molding pressure is low, so the mold material is mostly cast aluminum or non-metallic materials manufacturing, the structure is relatively simple.

05Press mold

There are two types of structural molds including compression molding and pressure injection molding. They are a class of molds used primarily to mold thermosetting plastics, and their corresponding equipment is a pressure molding machine.

Compression molding method according to the characteristics of the plastic, the mold will be heated to the molding temperature (generally in 103 ° 108 °), and then the measured compression molding powder into the mold cavity and charging chamber, close the mold, the plastic in the high heat, high-pressure action is soft viscous flow, after a certain period of time curing and shaping, to become the desired shape of the product.

Pressure injection molding and compression molding is different from no separate charging chamber, mold closed before molding, the plastic in the charging chamber to complete the preheating was viscous flow state, adjusted under pressure squeezed into the mold cavity, hardening molding.

Compression molds are mainly composed of cavities, charging cavities, guiding mechanisms, push-out parts, heating systems and so on. Pressure injection molds are widely used in encapsulating electrical components. The materials used in the manufacture of compression molds are basically the same as injection molds.
