Lateral runner 262 between root longitudinal direction runner 261, is shown by mold flow analysis, utilizes the utility model injection mold
The deformation of products amount of 2 injection molding of flow passage structure greatly reduces the deflection of product at 0.50 millimeter or so, wants to meet
The design requirement of the high automobile instrument panel outer framework 1 of refinement degree, while the flow passage structure 2 is equally applicable to and automobile instrument panel
On the similar high-precision product of outer framework 1.
In sky between the first order runner 24 and second level runner 23 of the flow passage structure 2 of the utility model injection mold
Between it is upper there is difference in height, second level runner 23 be connected to one end of sprue 21, and high ladder runner 26 has two longitudinal direction shuntings
Road 261 and Duo Gen are connected to the lateral runner 262 between two longitudinal runners 261, two longitudinal runners 261 across ground
Both ends be respectively communicated with second level runner 23 and first order runner 24.Spatially there is height using the connection of high ladder runner 26
The first order runner 24 and second level runner 23 of difference are spent, to make have the plasthetics of high drop in injection molding production process
In, there is no inside contract or outer swollen problem, dimensionally stable are indeformable.Also, high ladder runner 26 is that flow passage structure 2 provides
Lower and left and right directions support force avoids deformation of products either in injection molding still in subsequent electroplating technology, it is ensured that produces
Product dimensionally stable improves the yields of production, and high production efficiency, production cost are low.
In addition, the type chamber of injection mold has mutual disconnected two ends, i.e. plasthetics is open type, the first order
Runner 24 is connected to two ends in space curve, thus make high drop and the plasthetics of open type injection molding production process
In, there is no inside contract or outer swollen problem, dimensionally stable are indeformable.Also, high ladder runner 26 is that flow passage structure 2 provides
