Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 2 and 3, a mold capable of ejecting a product in multiple directions includes a core plate 3, a core plate 2, an upper fixing plate 1, a lower fixing plate 7, mold legs 4, an upper ejector plate 5, a lower ejector plate 6, a core insert 9, a core insert 8, a first slide block 11, an inclined guide pillar 13, a first ejector pin 17, a second slide block 14, a shifting block 15, and a second ejector pin 16. The female die plate 2 is fixed at the bottom of the upper fixing plate 1, the female die core 8 is fixed in a bottom accommodating groove of the female die plate 2, correspondingly, the male die plate 3 is fixed at the top of the lower fixing plate 7 through the die feet 4, and the male die core 9 is fixed in a top accommodating groove of the male die plate 3. The first sliding block 11 and the second sliding block 14 are arranged in the top containing groove of the male template 3. The top of the lower fixing plate 7 is also provided with an upper ejector plate 5 and a lower ejector plate 6.
The core insert 9 has a first wall 9.1 and a second wall 9.2 for forming a first inner wall 10.1 and a second inner wall 10.2 of the product 10, respectively; the male die core 9 is also provided with a first thimble hole and a slide block hole which are communicated to the second wall 9.2 and a second thimble hole which is communicated to the first wall 9.1, the ejection end of the first thimble 17 is slidably arranged in the first thimble hole, the other end of the first thimble is connected with the upper thimble plate, the ejection end of the second thimble 16 is slidably arranged in the second thimble hole, and the other end of the second thimble is connected with the second slide block 14.
The second sliding block 14 is provided with a shifting block groove/hole 14.1, the shifting block groove/hole 14.1 is provided with a parallel and opposite sliding block inclined surface 14.2, one part of the shifting block 15 is slidably arranged in the shifting block groove/hole 14.1, the part is provided with a shifting block inclined surface 15.1 which can be in sliding fit with the sliding block inclined surface 14.2, and the end part of the other part is connected with the upper ejector plate 5. A certain gap D is formed between the slide block inclined surface 14.2 and the corresponding shifting block inclined surface 15.1.
The inner end of the first sliding block 11 is arranged in the sliding block hole, the end face of the first sliding block is provided with an inverted groove 11.2, the part of the first sliding block outside the sliding block hole is provided with an inclined guide post groove/hole 11.1 which is obliquely arranged, and a part of an inclined guide post 13 is slidably arranged in the inclined guide post groove/hole 11.1. One side of the cavity insert 8 is connected with a heel block 12, and the inclined guide post 13 is connected with the heel block 12 so as to move along with the cavity insert 8.
The cavity insert 8, the first thimble 17 and the shifting block 15 all move along a first direction, and the first slide block 11, the second slide block 14 and the second thimble 16 all move along a second direction, wherein the first direction is perpendicular to the second wall 9.2, and the second direction is perpendicular to the first direction. As a typical construction, the first wall 9.1 is also perpendicular to the second wall 9.2.
As shown in fig. 4 to 7, when the cavity insert 8 and the core insert 9 are assembled, the product 10 is injection molded, and after the product 10 is formed, the cavity insert 8 is gradually separated from the core insert 9 under the driving of the upper fixing plate 1 and the cavity plate 2. In the process, the inclined guide post 13 moves synchronously, under the matching action of the inclined guide post groove/hole 11.1, the first slide block 11 moves in the slide block hole, the inner end of the first slide block is gradually far away from the first wall 9.1, and finally the inverted buckle groove 11.2 on the end surface is separated from the inverted buckle 10.1 on the first inner wall 10.3 of the product 10, so that convenience is provided for the next ejection.
As shown in fig. 8, after the undercut 10.1 is removed, the cavity core 8 continues to move, at this time, the upper ejector plate 5 drives the first ejector pins 17 and the shifting blocks 15 to move along the moving direction of the cavity core 8, at this time, the ejection ends of the first ejector pins 17 extend out of the first ejector pin holes to be higher than the second wall 9.2, and the second inner wall 10.2 supporting the product 10 ejects the product 10 along the same direction. Since a certain gap D exists between the block shifting inclined surface 15.1 of the block shifting 15 and the corresponding slide block inclined surface 14.2 of the second slide block 14, the second slide block 14 is not driven to move by the block shifting 15 in the process. At this time, the undercut 10.1 of the product 10 is still restrained by the structure of the core insert 9 and cannot be ejected further, so that the second stage of ejection is required.
As shown in fig. 9 and 10, after the upper ejector plate 5 continues to move to make the gap D between the shifting block inclined surface 15.1 of the shifting block 15 and the corresponding slider inclined surface 14.2 of the second slider 14 disappear and make the two contact, the movement of the shifting block 15 drives the second slider 14 to move, the second slider 14 drives the second ejector pin 16 to move, at this time, the ejecting end of the second ejector pin 16 extends out of the second ejector pin hole to push the first inner wall 10.3 of the product 10 to eject the product 10 in the same direction, so that the back-off 10.1 is not obstructed, and at this time, the product 10 can be smoothly demolded.
After demolding is finished, the upper ejector pin plate 5 is reset, the first ejector pin 17 and the shifting block 15 move in opposite directions successively, at the moment, the ejection end of the first ejector pin 17 retracts into the first ejector pin hole, and the other shifting block inclined surface 15.1 of the shifting block 15 contacts the corresponding slide block inclined surface 14.2 of the second slide block 14 so as to move the second slide block 14 in the opposite direction, so that the ejection end of the second ejector pin 16 retracts into the second ejector pin hole. The inclined guide post 11 is reset along with the cavity insert 8, at the moment, the first slide block 11 and the inner end thereof move to the direction of the first wall 9.1 to return to the initial position, and then the mold is closed again to continue the production of the next mold product 10.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
