Description
Technical field
The utility model is related to Injection Mold Design technical fields, more specifically, it relates to a kind of effective injection molding of coiling
Mold.
Background technology
Injection mold is a kind of tool producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Tool；The plastics of heated thawing are injected into die cavity by injection molding machine high pressure and obtain formed products after cooling and solidifying；For be molded around
The injection mold of spool is known as the effective injection mold of coiling.
Existing bobbin is shown referring to Fig.1 comprising plastic pipe 81, for for cable winds；81 lateral wall of plastic pipe
Spacing ring 82 there are three being integrally formed, to limit the position of cable winds；Generally pass through side axle cored structure in existing mold（In figure
It is not shown）Complete the molding of 8 lateral wall of bobbin；The madial wall of bobbin 8 completes molding jointly by two core bars 91；Wherein
One core bar 91 is moved together with dynamic model 93；Another core bar 91 sliding be arranged on cover half 9, and with 9 upper cylinder of cover half
92 piston rod connection.When die sinking, first, the piston rod of oil cylinder 92 pulls the core bar 91 on cover half 9, will be on cover half 9
The extraction out of bobbin 8 of core bar 91；Then, side core drawing structure along plastic pipe 81 radially away from bobbin 8；Meanwhile dynamic model
93 move to far from 9 direction of cover half, and bobbin 8 is driven to move, after die sinking, by bobbin 8 from 93 mo(u)ld top half core bar 91 of dynamic model
It removes.
But when the extraction out of bobbin 8 of the core bar 91 on cover half 9, the inside of bobbin 8 is in the state of negative pressure；
Since the tube wall of bobbin 8 is relatively thin, and plastic pipe 81 has higher temperature, the tube wall for being easy to cause bobbin 8 internally recessed
Sunken phenomenon causes the raising of product fraction defective.
