The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1 and Figure 2, the utility model automobile door frame bar injection mold comprises dynamic model 1, cover half 2, runner 3, ejecting mechanism 4 and mould bases 5.Mould bases 5 is used to support dynamic model 1, cover half 2 and ejecting mechanism 4.Cover half 2 is fitted with dynamic model 1 and is formed the airtight die cavity identical with the automobile door frame strip.Dynamic model 1 is provided with and pushes up 6 always, and this directly pushes up 6 and is embedded in the dynamic model 1.Dynamic model 1 die cavity is arranged on the straight top 6, directly pushes up 6 and is provided with the into mouth of a river mold insert 601 of glue.
As shown in Figure 3, Figure 4, runner 3 in the present embodiment comprises hot flow path 301 and cold runner 302, cold runner 302 directly is connected with the die cavity of dynamic model 1, and hot flow path 301 is connected by the hot mouth of open type with cold runner 302, and cold runner 302 is connected by the ox horn mouth with dynamic model 1 die cavity.The hot mouth of open type is provided with 8, and the ox horn mouth is provided with 17.Wherein, cold runner 302 is arranged in the mouth of a river mold insert 601, and after injection was finished, cold runner 302 linked together with goods 7.
As shown in Figure 7, ejecting mechanism 4 comprises thimble 401 and top board, and wherein top board comprises first top board 402, second top board 403, oil cylinder 404, base 408.Oil cylinder 404 drives first top board 402 and 403 motions of second top board.Base 408 is fixed on the mould bases 5.Thimble 401 is arranged on second top board 403, has on the mouth of a river mold insert 601 and is convenient to the hole that thimble 401 passes, thereby second top board 403 drives thimble 401 motions cold runner 302 is ejected, and itself and goods 7 are separated.First top board 402 is arranged on the below of second top board 403, and the cylinder rod of oil cylinder 404 passes first top board 402 and is connected with second top board 403.Cylinder rod comprises guide rod 4041 and end bar 4042, is cylindrical, and the diameter of end bar 4042 is greater than the diameter of guide rod 4041.First top board 402 is provided with and the seam of holding bar 4042 to cooperate, the degree of depth of seam guarantees to finish at thimble 401 and ejects before cold runner 302 action promptly for the first time ejects action, therefore end bar 4042 contact with inner stopper, in that to eject for the first time in the process first top board 402 not mobile.Can not move in order to guarantee that further first top board 402 ejected in the process in the first time, base 408 is provided with first deduction, 405, the first deductions 405 that block first top board 402 and is connected with base 408 by back-moving spring 407.Second top board 403 be provided with the engagement of first deduction 405 second deduction 406, when oil cylinder 404 drivings second top board 403 moves, second deduction 406 also moves with second top board 403, and second deduction 406 can drive first deduction 405 and move, and itself and first top board 402 are broken away from.When first deduction 405 moves, back-moving spring 407 compression, when first deduction 405 and first top board 402 broke away from fully, back-moving spring 407 reinstatements drove first deduction 405 and get back to initial position.
As Fig. 5, shown in Figure 6, be provided with dynamic model cooling water channel 8 at the back side of dynamic model 1, be provided with cover half cooling water channel 9 at the back side of cover half 2 in order to obtain better cooling effect, the shape of cooling water channel must be consistent with the shape of die cavity.Cooling water channel in the present embodiment adopts straight tube and inclined tube, cools off dynamic model 1 and cover half 2 fully.
The course of work of the utility model automobile door frame bar injection mold mainly comprises matched moulds, injection, die sinking, ejects four steps.After the mould die sinking, have only cold runner 302 and goods 7 to connect together, hot flow path 301 has separated with cold runner 302.Because goods 7 complete cycles are back-off, so in the goods 7 straight tops 6, demoulding difficulty.The process of ejecting comprises and ejecting for twice, ejects cold runner 302 for the first time, and it is separated with goods 7, ejects straight top 6 for the second time.
For the first time eject process as shown in Figure 8, oil cylinder 404 drives second top board 403 and moves, and the thimble 401 on second top board 403 ejects cold runner 302, and itself and goods 7 are broken away from.Ejecting in the process for the first time, the end bar 4042 of cylinder rod does not contact with inner stopper on first top board 402, and first top board 402 can not move, and directly pushes up 6 and can not move yet.Simultaneously, first deduction 405 also blocks first top board 402, stops it to move.Move in 403 processes of moving at second top board, second deduction 406 drives first deduction 405 and moves, back-moving spring 407 compressions.When for the first time ejecting when finishing, first deduction 405 breaks away from first top board 402, and the end bar 4042 of while cylinder rod contacts with the inner stopper on first top board 402.
For the second time eject process as shown in Figure 9, the end bar 4042 of cylinder rod contacts with inner stopper on first top board 402, and oil cylinder 404 driving first top boards 402 and second top board 403 move simultaneously, eject straight top 6.Because first deduction 405 and first top board 402 break away from fully, back-moving spring 407 restores to the original state and makes first deduction 405 get back to initial position.
See also Figure 10,, must be used for manipulator it is pulled out straight top 6 by force because goods 7 are stuck in the straight top 6.Automobile door frame bar hardness in the present embodiment is higher, therefore in the process of the demoulding straight top 6 and goods 7 all must reach uniform temperature, be 80 ℃ in the present embodiment, make goods 7 demouldings smoothly, can not damage goods 7.
In conjunction with the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
