Circular cross section, and the diameter of the cross section is identical as the internal diameter of the second slot section 217b, that is to say, that insertion space 11
Inner wall and core pulling needle 23 side wall between right half part (Fig. 2 institute of the gap that is formed to the trunk portion of shaped article 200
The right side shown).
Referring to Fig. 5, in the present embodiment, support actuator 15 is but is not limited to oil cylinder, convergence piece 13 respectively with support
Actuator 15 and support plate 14 connect, and the merging slot 141 slid in and out for the convergence piece 13 is offered in support plate 14.
Support plate 14 includes being connected with each other upper plate body 142 and lower body 143, the top end part of the first oblique top part 17, the second oblique top part 18
Top end part is slidably connected at respectively between upper plate body 142 and lower body 143.Return unit 16 is but is not limited to reset back stitching, multiple
The upper end of position back stitching is fastened between upper plate body 142 and lower body 143.Convergence piece 13 is bar shape, and the top surface of upper plate body 142 is opened
Equipped with merging slot 141, the cross dimensions of the merging slot 141 is greater than the cross dimensions of convergence piece 13, and is placed in slot 141 through upper
The top and bottom of plate body 142, that is to say, that say, in die sinking, support actuator 15 drives 13 pushing tow lower body 143 of convergence piece
It moves down, when support plate 14 moves down, the first oblique top part 17 and the second oblique top part 18 divide under the corresponding inclined hole effect of solid plate
Two sides (left and right of diagram) be not mobile to the left and right；And in molding, injection molding machine pushes dynamic model part molding, and dynamic model part pushes multiple
Position back stitching movement moves upwards, under the action of resetting back stitching, 14 return of support plate, and then the first oblique top part 17, the second oblique top
Part 18 resets in place.It should be noted that when reset, supports actuator due to pushing support plate 14 when support actuator 15 ejects
15 can not drive support plate 14 to move up, and the first oblique top part 17, the second oblique top part 18 is allowed to be kept open, and transport to core pulling needle 23
Dynamic space, to avoid interfering when molding with line position seat 21 and core pulling needle 23, to guarantee the smooth complete of open mold movement
At.In this way, when die sinking is completed, 13 return of convergence piece is prepared for next circulation.
Referring to Fig. 7, cover half part 10, which is provided with, supports the lock module 19 (also referred to as shovel) on line position seat 21 in molding,
There is lock module 19 the sliding bevel 19a being pressed on line position seat 21 to be provided with wear plate on line position seat 21 in the present embodiment
25, the sliding bevel 19a of lock module 19 is supported on wear plate 25 when molding, and pushing tow line position seat 21 moves right, and presses simultaneously
Tight line position seat 21.It should be noted that on the section perpendicular to second direction D2, H1>H2+2mm, wherein H1 is line position drive
Moving part 22 under complete ejection state and, when lock module 19 is not contacted with line position seat 21, the connection head component 241 of connecting component 24
Spacing between the limiting section 216 of 215 left end of sliding groove, H2 are 211 upper right side of line position front and the first oblique top part 17 (or the
Two oblique top parts 18) lower-left section between spacing, that is to say, that in H1>When H2+2mm, it can be ensured that smoothly molding meets mold
Regular event；And work as H1<When H2, due to the button bit of product 200, the first oblique top part 17,18 nothing of the second oblique top part in clamping process
Method return is not to be able to satisfy mold actions.Specifically, in clamping process, the total kilometres L=line position actuator 22 of line position seat
Stroke+shovel base driving trip.
Referring to Fig. 7, as further optimizing, be provided on line position rear portion 212 for molding when and moving template mould
