 Design Standards and Key Points of Automotive Injection Molding Locating Rings


The mold locating ring refers to the front part of the mold, which is the locating centering device for loading the fixed mold part into the fixed plate of the injection molding machine. It should be matched with the locating hole of the injection molding machine to ensure the centering of the mold; The machine nozzle can accurately align the mold sprue sleeve, so that the molten plastic can successfully complete the injection process, and the prerequisites for producing qualified products

 

1.  Design criteria for locating rings

According to various injection molding machines, the requirements for the locating ring are different. The outer diameter of the locating ring of the automobile injection mold is usually 100MM, 150MM, 250MM. The size of the locating ring must be designed and manufactured according to the customer's standard.


2.  Design points of locating circle

1) The sprue bushing should at least sink into the panel 2MM to ensure that the sprue bushing is protected when the die is not installed.

2) Some customers require the structure of the locating ring to be reversed on the panel.

3) When the single-point hot nozzle is feeding, the locating ring must be pressed against the head of the thermal nozzle to prevent the hot nozzle from loosening and leaking.
