The problem of among the prior art oblique top structure of loosing core a plurality of oblique ejector pins at the in-process of moving towards one direction slope, appear the problem of interfering mutually between a plurality of oblique ejector pins or between oblique ejector pin and other spare parts and then lead to oblique top structure of loosing core unable normal drawing of patterns or compound die is solved.
Description
Technical field
The present invention relates to injection mold technologies, and in particular to a kind of inclined-ejection core pulling mechanism and the injection molding with the structure
Mold.
Background technique
Inclined-ejection core pulling mechanism is the mechanism for being used to formed product back-off in mold design.In part injection molding process,
Inclined-ejection core pulling mechanism is often needed to use, such as its nozzle outer circle position needs to be buckled to using whole circle when producing washing machine placket
Structure, whole circle back-off structure can prevent the annular nozzle position of washing machine placket from the problem of infiltration outward occur, guarantee laundry
The sealing effect of machine placket.It needs to complete molding work of the plastic at back-off using inclined-ejection core pulling mechanism to process back-off structure
Make and successfully ejects plastic.
It is needed when using the multiple back-off structures of existing inclined-ejection core pulling mechanism simultaneous processing and whole circle back-off structure multiple
Oblique top moves simultaneously, needs in the angle ejector rod for being added product outer peripheral contour that multiple movements are arranged, one end of angle ejector rod and dynamic model
It is connected and is slidably arranged on guide pad, the other end is connected with the side mold insert for being used to form whole circle back-off structure, guide pad
The upper horizontal concrete chute that product back-off direction level sliding is directed away from the above-mentioned angle ejector rod of guidance, dynamic model and cover half are dynamic when separating
Mould will drive angle ejector rod and move downward therewith, and angle ejector rod, can court while vertical motion under the action of guide pad at this time
Direction movement far from product surface realizes whole circle back-off structure molding to drive side mold insert to be detached from product back-off structure.
But the angle ejector rod of above-mentioned inclined-ejection core pulling mechanism needs be driven simultaneously towards a direction inclination movement, when needing to process
Multiple back-off structures, especially when carrying out whole circle back-off processing to product, it is necessary to which multiple angle ejector rod collective effects are meeting
Ejection distance in the case where will appear multiple angle ejector rods during inclination movement facing one direction between multiple angle ejector rods or
The problem of interfering with each other between angle ejector rod and other components makes staff be difficult to be simutaneously arranged in a limited space
Multiple angle ejector rods complete whole circle back-off processing, and each angle ejector rod also needs to be connected with driving mechanism and will appear mold occupancy sky
Between big problem.
Summary of the invention
Therefore, the present invention is intended to provide a kind of inclined-ejection core pulling mechanism and the injection mold with the structure, existing to solve
Inclined-ejection core pulling mechanism its multiple angle ejector rod in technology during inclination movement facing one direction, between multiple angle ejector rods or
The problem of interfering with each other between angle ejector rod and other components causes inclined-ejection core pulling mechanism normally not demould or close in turn
The problem of mould.For this purpose, the present invention provides a kind of inclined-ejection core pulling mechanism, including
