Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 - Figure 6 The present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] An automatic device capable of separating the iron core from the mold after overall injection molding, including an operating table 1 and a box body 2. The connection between the operating table 1 and the box body 2 is supported by a first support column 3. The surface of the first support column 3 is slidably connected with a storage plate 5 through a first sliding sleeve 4. The top of the storage plate 5 is fixedly connected with a support block 6. The top of the support block 6 is fixedly connected with a support rod 7. The top of the support rod 7 penetrates through the top of the storage plate 5 and is movably connected with a lower die block 8. The top of the lower die block 8 is provided with an upper die block 9. A plurality of injection holes 10 are opened at the top of the upper die block 9. A demolding mechanism is arranged on the top of the storage plate 5, and a downward pressing mechanism is arranged inside the box body 2;

[0028] The demolding mechanism includes first clamping cylinders 11 symmetrically and fixedly installed at the bottom of the placement plate 5. The output end of the first clamping cylinder 11 is fixedly connected to a first sliding block 12. The top of the first sliding block 12 is fixedly connected to a transmission block 13. The top of the transmission block 13 is fixedly connected to a lower mold clamping block 14. Second clamping cylinders 15 are symmetrically and fixedly installed at the bottom of the box body 2. The output end of the second clamping cylinder 15 is fixedly connected to a second sliding block 16. The bottom of the second sliding block 16 is fixedly connected to an upper mold clamping block 17. A downward pulling cylinder 18 is fixedly installed inside the operation table 1. The output end of the downward pulling cylinder 18 is fixedly connected to the bottom of the placement plate 5.

[0029] In this embodiment, considering that in the existing iron core injection molding, glue is injected into the mold for molding, and the solidification of the glue will also adhere the mold to the iron core, making it difficult to demold. The manual demolding method is time-consuming and laborious, and it is easy to cause iron core locking. Therefore, by setting up the demolding mechanism, the placement plate 5 can be lifted to a position flush with the support rod 7 by starting the downward pulling cylinder 18. Then, the injection-molded mold is placed on the placement plate 5. At the same time, the first clamping cylinder 11 and the second clamping cylinder 15 are started, driving the first sliding block 12 and the second sliding block 16 to move respectively, so that the upper mold clamping block 17 and the lower mold clamping block 14 respectively fix the upper mold 9 and the lower mold 8. Then, the downward pulling cylinder 18 is started again to stretch downward, driving the placement plate 5 to move downward, so that the lower mold 8 is separated, and the iron core stays on the support rod 7, achieving the effect of separating the iron core from the mold.

[0030] It solves the problem that considering that in the existing iron core injection molding, glue is injected into the mold for molding, and the solidification of the glue will also adhere the mold to the iron core, making it difficult to demold. The manual demolding method is time-consuming and laborious, and it is easy to cause iron core locking.

[0031] A first guide rail 24 for cooperating with the first sliding block 12 is fixedly installed at the bottom of the placement plate 5. A second guide rail 25 for cooperating with the second sliding block 16 is fixedly installed at the bottom of the box body 2.

[0032] In this embodiment, by setting the first guide rail 24 and the second guide rail 25, the moving trajectories of the first sliding block 12 and the second sliding block 16 can be restricted, and at the same time, their movement can be made more stable, enabling the lower mold clamping block 14 and the upper mold clamping block 17 to accurately clamp the upper mold 9 and the lower mold 8.

[0033] The clamping parts of the lower mold clamping block 14 and the upper mold clamping block 17 are both arc-shaped.

[0034] In this embodiment, by setting the clamping parts of the lower mold clamping block 14 and the upper mold clamping block 17 to be arc-shaped, the shape of the mold can be better fitted, and the upper mold 9 and the lower mold 8 can be clamped and fixed.

[0035] A pressing block 26 is fixedly connected to the clamping portion of the lower die clamping block 14, and the pressing block 26 is arc-shaped.

[0036] In this embodiment, by setting the pressing block 26, when the lower die clamping block 14 clamps and fixes the lower die block 8, the pressing block 26 will just press on the top of the lower die block 8. When the pulling cylinder 18 drives the placing plate 5 to move downward, it can be easier to separate the lower die block 8.

[0037] Embodiment Two:

[0038] On the basis of Embodiment One, in this embodiment, the demolding mechanism can automatically separate the lower die block 8 from the iron core. However, considering that some glue solidified substances will be located in the injection hole 10 of the upper die block 9, if not removed, it will also affect the demolding effect of the mold. In this application, the downward pressing mechanism includes a support plate 19 arranged in the box body 2. The connection between the support plate 19 and the box body 2 is supported by a second support column 20. The surface of the second support column 20 is slidably connected with a lower pressing plate 21 through a second sliding sleeve 27. A downward pressing rod 22 is fixedly connected to the bottom of the lower pressing plate 21. A downward pressing cylinder 23 is fixedly installed on the top of the support plate 19, and the output end of the downward pressing cylinder 23 is fixedly connected to the top of the lower pressing plate 21.

[0039] In this embodiment, considering that some glue solidified substances will be located in the injection hole 10 of the upper die block 9, if not removed, it will also affect the demolding effect of the mold. Therefore, by setting the downward pressing mechanism, by starting the downward pressing cylinder 23, the lower pressing plate 21 and the downward pressing rod 22 can be driven into the injection hole 10 to squeeze out the glue solidified substances in the injection hole, and then the upper die block 9 can be easily separated from the iron core, achieving the effect of facilitating demolding.

[0040] It solves the problem that considering that some glue solidified substances will be located in the injection hole 10 of the upper die block 9, if not removed, it will also affect the demolding effect of the mold.

[0041] The number of the downward pressing rods 22 is several, and they are opposite to the positions of the injection holes 10.

[0042] In this embodiment, by setting the downward pressing rods 22, the downward pressing rods 22 can enter the corresponding injection holes 10 respectively to squeeze out the glue solidified substances in the injection holes, and then the upper die block 9 can be easily separated from the iron core.

[0043] The bottom of the downward pressing rod 22 is conical.

[0044] In this embodiment, by setting the bottom of the downward pressing rod 22 to be conical, it is convenient for the downward pressing rod 22 to enter the inside of the injection hole 10 to squeeze out the glue solidified substances.

[0045] Working principle: The user raises the storage plate 5 to a position flush with the support rod 7 by activating the pull-down cylinder 18. Then, place the injection-molded mold on the storage plate 5. At the same time, activate the first clamping cylinder 11 and the second clamping cylinder 15 to drive the first sliding block 12 and the second sliding block 16 to move respectively, so that the upper mold clamping block 17 and the lower mold clamping block 14 fix the upper module 9 and the lower module 8 respectively. Then, activate the pull-down cylinder 18 again to stretch downward, driving the storage plate 5 to move downward, so that the lower module 8 disengages, and the iron core stays on the support rod 7, achieving the function of separating the iron core from the mold;

[0046] At the same time, by activating the downward pressure cylinder 23, drive the lower pressure plate 21 and the lower pressure rod 22 into the injection hole 10 to squeeze out the solidified glue in the injection, and then the upper module 9 can be easily separated from the iron core, achieving the function of facilitating demolding;

[0047] It should be noted that either of the above two steps can be carried out first, and there will be no conflict between them.

[0048] It should be noted that the cylinder is a device or equipment existing in the prior art, or a device or equipment that can be realized by the prior art, and the specific composition and principle of the power supply of the cylinder are clear to those skilled in the art, so it will not be elaborated in detail.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
