Rotating junction forming cavity 38, the rotating junction forming cavity 38 have several groups, the rotating junction forming cavity of difference group
38 differ at a distance from frame forming core 31 edge, and same group of rotating junction forming cavity 38 is cylinder by one
Axis hole forming core 39 penetrates through.
Rotating junction forming cavity 38 is used for the molding of rotating junction, and rotating junction makes staving and bung rotate to connect
It connects, rotating junction forming cavity 38 has shapes the different several groups of 31 Edge Distance of core with frame, may make system in this way
The bung obtained can select the rotating junction of different location be attached according to the openings of sizes of staving, therefore realize and a variety of openings
There is the purpose that plastic barrel of different sizes matches wider application range, cylinder axis hole forming core 39 to run through
Cross same group of rotating junction forming cavity 38 so that axis hole is formed on rotating junction, axis hole is matched with the shaft on staving
It closes and realizes rotation connection, axis hole forming core 39 can be done with respect to moving platen 2 along the sliding perpendicular to 2 sidewall direction of moving platen, opened
When mould, axis hole forming core 39 is first set to skid off moving platen 2 from side, then solid plate 1 and moving platen 2 is made to detach.
As shown in figure 4, further including several pieces of buffer part forming core 3a for protruding from 32 upper surface of cover board forming core, institute
Buffer part forming core 3a is stated to connect with the edge of frame forming core 31 by arc surface, the buffer part forming core 3a's
Thickness is less than the half of frame forming 31 thickness of core, and buffer part can play buffering when bung is by external impact force
Effect, buffer part shape core 3a by arc surface and frame forming core 31 edge connect can reduce buffer part side by
The probability of additional impact force, the thickness that buffer part shapes core 3a can less than the half of frame forming 31 thickness of core
While so that buffer part is played preferable cushioning effect, also it is unlikely to so that the thickness of bung entirety is excessive.
As shown in figure 3, further including several knock-pins 4, one end of the knock-pin 4 extends into moving platen 2, with second
Forming face 21 is connected to, and after cooling and shaping, knock-pin 4 does the sliding of opposite moving platen 2, completes the knockout course of product, it is preferable that
Wherein there is one end of several knock-pins 4 to be located in frame forming core 31, and be circumferentially uniformly distributed along frame forming core 31,
The end of at least one knock-pin 4 is located in cover board forming core 32, can be ejected product so that in ejection process in this way
Be more uniformly stressed, reduce the probability that product damages in ejection process.
As shown in figure 4, further including several pieces of molding locating pieces 5 for protruding from 2 surface of moving platen, moving platen 2 and solid plate 1
It can be positioned according to molding locating piece 5 in molding, to be in when the first forming face 12 and the second forming face 21 being made to be molded
Corresponding position ensure that the quality of injecting products.
The operation principle of the utility model is：In use, moving platen 2 is molded with solid plate 1, to 12 He of the first forming face
Second forming face 21 is combined as forming cavity 3, the plastic cement of molten condition from injection molding machine by 11 injection molding chamber 3 of injection hole,
After cooled and solidified, it is made integrally formed cover board and frame, several orthogonal first resistance to stress decorative pattern forming cavities 34 and the
Two resistance to stress decorative pattern forming cavities 35 are distributed in cover board upper surface so that and the stress resistance of the plastic barrel bung of injection molding can be strong,
The problem of being less likely to occur to crack because of the variation of external force, humidity or temperature, when being molded after the completion of injection molding, first by axis hole forming
Core 39 extracts moving platen 2 out, then opens solid plate 1 and moving platen 2, and injecting products are ejected using knock-pin 4, when being assembled with staving,
The rotating junction of different location is selected to be rotatablely connected according to the openings of sizes of staving.
