The specific embodiment
A kind of injection moulding workpiece 100 that has a right angle terminals as shown in Figure 1, the right angle terminals 103 that is bent into 90 ° is encapsulated in the workpiece 100 as inserts, right angle terminals 103 can have side by side a plurality of.After the injection mo(u)lding, form the first back-off portion 101 and the second back-off portion 102 respectively in rear portion and the front portion of right angle terminals 103.
As shown in Figure 2, the present invention does not have the gap stripper apparatus and comprises a holder 40, push rod 6, first pushing block 8 and second pushing block 9, and wherein, push rod 6, first pushing block 8 and second pushing block 9 all can slide in holder 40.
In the present embodiment, holder 40 is formed by fixedly connecting by fixed block 5, take-up housing 4 and handle 2, take-up housing 4 be fixedly connected on fixed block 5 above, and spacing by pin 3; Handle 2 by screw 1 be fixedly connected on take-up housing 4 above.
In holder 40, be provided with first confined planes 51 and second confined planes 52; First confined planes 51 and second confined planes 52 are arranged on the fixed block 5, and the front end face (illustrated right side) with first pushing block 8 and second pushing block 9 is relative respectively.Hereinafter alleged front end all refers to illustrated right-hand member, and the rear end refers to illustrated left end.Be provided with the first sliding stroke L1 between the front end face of first pushing block 8 and first confined planes 51, represent that first pushing block 8 can be with respect to the scope of holder 40 slips.Also fixedly there is banking pin 7 side of first pushing block 8, holder 40 is provided with the spacing elongated slot 42 (as shown in Figure 3) that is slidingly matched with described banking pin 7, banking pin 7 and spacing elongated slot 42 have limited the length of the first sliding stroke L1, can avoid first pushing block 8 to deviate from from holder 40.
Continuation is with reference to Fig. 2, and the top of first pushing block 8 is provided with preceding barricade 81 and back barricade 82; Second pushing block 9 is located in the top of first pushing block 8 and between forward and backward barricade 81,82, second pushing block 9 can slide in holder 40 with first pushing block 8, is provided with the second sliding stroke L2 between the front end face of second pushing block 9 and second confined planes 52.Simultaneously, second pushing block 9 can slide with respect to first pushing block 8 between forward and backward barricade 81,82, and its scope of sliding relatively is the 3rd sliding stroke L3.Preferred design is: L1=L2+L3.The face that is slidingly matched 89 between second pushing block 9 and first pushing block 8 is the inclined-plane.
Second pushing block 9 is provided with locating slot 91 and locating piece 10, and the front end of locating slot 91 ends at the trailing flank of locating piece 10.Locating slot 91 just in time can hold right angle terminals 103, after right angle terminals 103 is put into locating slot 91, can be with second pushing block 9 surperficial concordant, the front end of right angle terminals 103 withstands on the trailing flank of locating piece 10, realizes the location.
The back barricade 82 of first pushing block 8 is provided with first protuberance, 83, the first protuberances 83 and extends forward along the end face of second pushing block 9.Take-up housing 4 is provided with second protuberance, 41, the second protuberances 41 and extends back along the end face of second pushing block 9, and is relative with first protuberance, 83 directions.
Utilize above-mentioned stripper apparatus that right angle terminals is carried out injection moulding below in conjunction with Fig. 4-10 explanation and seal the also process of the demoulding.
The first step, as shown in Figure 4, first pushing block 8 is in the maximum position of releasing from holder 40, right angle terminals 103 is put into the locating slot of second pushing block 9.
Second step as shown in Figure 5, promoted 6mm to the right with first pushing block 8, the back barricade that makes first pushing block 8 and 9 applyings of second pushing block, first protuberance 83 be pressed in right angle terminals 103 above, the rear portion of right angle terminals 103 is compressed.Push rod 6 is also ejected 6mm by first pushing block 8.
The 3rd step, as shown in Figure 6, the assembly that first pushing block 8, second pushing block 9, locating piece 10 and right angle terminals 103 are formed in continuation is turned right and is promoted 12mm, and the front end face of first pushing block 8 and first confined planes are fitted, stop motion, second pushing block 9 and second confined planes also fit together simultaneously.Second protuberance 41 also be pressed in right angle terminals 103 above, simultaneously, because the face of being slidingly matched between second pushing block 9 and first pushing block 8 is inclined-plane (3 ° angle being arranged with the bottom surface of first pushing block 8), when the combinations thereof body moves to right, produce the wedge effect, produce locking pressure when mobile in take-up housing 4, right angle terminals 103 is fastened in the stripper apparatus firmly.At this moment: the gap between first confined planes 51 of first pushing block 8 and fixed block 5 is 0mm, gap between second confined planes 52 of second pushing block 9 and fixed block 5 is 0mm, and the assembly that first pushing block 8, second pushing block 9, locating piece 10 and right angle terminals 103 are formed can not produce displacement.
The 4th step, as shown in Figure 7, after above-mentioned action is finished, stripper apparatus of the present invention is put into the injection mold matched moulds, carry out injection mo(u)lding processing, finish workpiece 100.
In the 5th step, as shown in Figure 8, after the injection mo(u)lding, take out stripper apparatus of the present invention.For taking out workpiece, should earlier workpiece fastening when moulding is sealed in injection moulding be discharged from mould emptier fully.For this reason, push rod 6 is imposed certain thrust, with first pushing block, the 8 past 6mm that move left.At this moment: form the 6mm gap between first pushing block 8 and first confined planes, also form the 6mm gap between the back barricade of first pushing block 8 and second pushing block 9, first protuberance 83 is deviate from from the first back-off portion 101 on the workpiece, and the demoulding obstacle at place, right angle, right angle terminals rear portion in the workpiece is removed.
The 6th step, as shown in Figure 9, continue push rod 6 is imposed thrust, first pushing block 8 is continued toward moving left 12mm.Simultaneously, the preceding barricade of first pushing block 8 drives second pushing block 9 together toward moving left 12mm.Be fixed on banking pin 7 on first pushing block 8 and slide into the high order end of spacing elongated slot 42, first pushing block 8 stops mobile.At this moment, the gap between first pushing block 8 and first confined planes is increased to 18mm; Gap between second pushing block 9 and second confined planes is 12mm, and second protuberance 41 is deviate from from the second back-off portion 102 on the workpiece, and the demoulding obstacle of right angle terminals front portion in the workpiece is removed.
In the 7th step, as shown in figure 10, workpiece 100 is discharged fully, can freely take out, and finishes a fabrication cycles.Then, put into a right angle terminals again, repeat said process, can enter the volume production cycle.
