The composition of precision injection mold according to the 'China Mold Industry Yearbook' compiled by China Mold Industry Association, injection mold accounts for the largest proportion of mold sales, accounting for about 45%; Stamping dies account for about 37%; Casting molds account for about 9%; A total of about 9% of other types of molds.
With the development of industry, China's requirements for mold precision are getting higher and higher, and it tends to develop precision injection molds.
Precision injection mold is mainly composed of eight systems, divided into: gating system, guiding system, molding system, core pulling system, ejection system, temperature regulating system, exhaust system and supporting parts.
Compared with other molds, precision injection molds require high precision, so they need to be designed in strict accordance with these eight systems.
Gating system refers to the passage through which molten plastic enters the mold cavity from the nozzle of the injection machine. It is mainly composed of mainstream passage, diversion passage, gate and cold material well.
The guiding system refers to the accurate matching of the mold when it is closed. It is mainly composed of a guide post, a guide sleeve, a positioning block, etc.
The molding system mainly refers to the movement, and the parts related to the mold cavity in the fixed mold part are mainly composed of mold kernels, inserts, etc. The core pulling system mainly consists of a slider (Line position), Inclined top, etc.
The ejection system refers to the device that the plastic is pushed out of the cavity after the mold is parting, mainly composed of thimble, top block, etc.
The temperature regulating system refers to the function of cooling the mold and cooling the waterway in order to meet the requirements of the injection process on the mold temperature.
The exhaust system means that the air in the molding cavity and the gas volatilized by the clinker itself are discharged out of the mold, which is mainly composed of the matching gap of each insert of the mold, the matching gap of the thimble and the additional exhaust groove.
Supporting system refers to the parts used for installing, fixing or supporting molding, parts and other mechanisms.
