Detailed Description
The present utility model will now be described in detail with reference to the accompanying drawings. The figure is a simplified schematic diagram illustrating the basic structure of the utility model only by way of illustration, and therefore it shows only the constitution related to the utility model.
As shown in fig. 1, the application provides an injection molding device for a turnover box, which comprises an upper die 1 and a lower die 2, wherein a plurality of sealing blocks 21 are fixedly arranged on the upper side of the lower die 2, and injection molding grooves 22 with upper side openings are formed between the sealing blocks 21. An injection block 11 corresponding to the injection groove 22 is fixed to the lower side of the upper die 1.
As shown in fig. 1, it will be appreciated that the injection molding apparatus is used to injection mold the transfer case 3, and the outer wall of the transfer case 3 is formed with the clasp 31.
As shown in fig. 1 to 3, the seal block 21 is provided with a through groove 23 corresponding to the position of the catch 31, and the through groove 23 communicates both sides of the seal block 21.
As shown in fig. 1 to 3, the molding device 4 is mounted in the through groove 23, the molding device 4 includes a fixed block 41 and a first slider 42 positioned in the through groove 23, the first slider 42 is positioned at the lower side of the fixed block 41, the fixed block 41 and the first slider 42 block the through groove 23, and raw materials are prevented from leaking from the through groove 23 during injection molding.
As shown in fig. 2 and 3, a driver 43 is fixed to a side of the through groove 23 away from the injection groove 22, in this embodiment, the driver 43 is a hydraulic rod, and an output end of the driver 43 is connected to the first slider 42 for pushing the first slider 42 to move.
As shown in fig. 2 and 3, the fixed block 41 is provided with a second slider 44 on a side close to the injection groove 22. The lower side of the second slider 44 is provided with a second inclined surface 441 facing the first slider 42, and the side of the first slider 42 close to the injection groove 22 is provided with a first inclined surface 421 parallel to the second inclined surface 441. When the driver 43 drives the first slider 42 to approach the injection slot 22, the first inclined surface 421 contacts and pushes the second inclined surface 441, so that the second slider 44 has a moving tendency.
As shown in fig. 2 and 3, two sides of the first inclined plane 421 are provided with a first sliding groove 422 parallel to the first inclined plane 421, and the second inclined plane 441 is provided with a first sliding bar 442 corresponding to the first sliding groove 422; the fixed block 41 is provided with a vertical second slide 411 near one side of the injection molding groove 22, and the second sliding block 44 is provided with a second sliding groove 443 corresponding to the second slide 411.
As shown in fig. 2 and 3, a shaping block 444 is provided on the upper side of the second slider 44, and a shaping groove 231 corresponding to the position of the shaping block 444 is provided on the inner wall of the through groove 23.
By sliding between the first sliding groove 422 and the first sliding groove 442 and sliding between the second sliding groove 411 and the second sliding groove 443, the second sliding groove 411 is guided, so that the second sliding groove 411 is prevented from being deviated, and the shaping block 444 is inserted into the shaping groove 231.
When the shaping block 444 is inserted into the shaping groove 231, the gap between the shaping block 444 and the shaping groove 231 is the same as the shape of the catch 31, so that raw materials are shaped into the catch 31 through the gap between the shaping block 444 and the shaping groove 231 during injection molding, and the effect of integrally forming the catch 31 and the turnover box 3 is achieved.
After the shaping block 444 is inserted into the shaping groove 231, the driver 43 continuously generates thrust to the first sliding groove 422, so that the reaction force of mutual extrusion between the second inclined plane 441 and the first inclined plane 421 drives the second sliding block 44 and the first sliding block 42 to cling to the inner wall of the through groove 23, raw material leakage is avoided on one hand, and burrs are avoided around the turnover box 3 on the other hand.
As shown in fig. 1 and 2, after the shaping block 444 is inserted into the shaping groove 231, one side of the first slider 42 and the second slider 44, which is close to the injection groove 22, is parallel to the inner wall of the injection groove 22, so as to ensure that the outer wall of the molded turnover box 3 is flat.
After the molding of the turnover box 3 is completed, when the driver 43 drives the first sliding block 42 to be far away from the injection molding groove 22, the first sliding groove 422 and the first sliding bar 442 are clamped and slid at this time, so that the first sliding block 42 drives the second sliding bar 411 to move downwards, and the shaping block 444 and the shaping groove 231 are separated, so that the catch 31 is released. When the sealing block 21 is detached after the upper die 1 and the lower die 2 are separated conveniently, the clamping of the buckling hand 31 is avoided, so that the sealing block 21 is difficult to detach or the buckling hand 31 is damaged.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
