[0027] The ejector assembly is located at the bottom end of the lower base 1 and is used for performing ejection operations on the injection molded parts.

[0028] Based on the above structure, the staff slides the lower mold 2 along the top of the lower base 1, and then turns the lower bolt 4 to fix the lower mold 2 to the top of the lower base 1 through the thread, so as to realize the quick installation operation of the lower mold core 3 at the top of the lower mold 2. Similarly, the staff slides the upper mold 8 along the bottom of the upper base 6, and then turns the upper bolt 9 to fix the upper mold 8 to the bottom of the upper base 6 through the thread, so as to realize the quick installation operation of the upper mold core 801 at the bottom of the upper mold 8.

[0029] In one embodiment, the cross-sections of the lower mold 2 and the upper mold 8 are both "T"-shaped.

[0030] In this embodiment, by providing the lower mold 2 and the upper mold 8 with "T"-shaped cross sections, it is beneficial to quickly position the lower mold 2 and the upper mold 8.

[0031] In one embodiment, the lower mold 2 forms a positioning structure with the lower base 1 through the lower bolts 4, and the upper mold 8 forms a positioning structure with the upper base 6 through the upper bolts 9.

Similarly, the staff turns the upper bolt 9 to fix the upper mold 8 to the bottom of the upper base 6 through the thread, thereby realizing a quick installation operation on the upper mold core 801 at the bottom of the upper mold 8.

[0033] In one embodiment, the ejector pin assembly includes:

[0034] The ejector frame 10 is fixedly connected to the bottom end of the lower base 1, the outer wall of the ejector frame 10 is threadedly connected to an adjusting bolt 11, one end of the adjusting bolt 11 is screwed to a connecting plate 12 which is slidably connected to the inner wall of the ejector frame 10, one end of the connecting plate 12 is fixedly connected to a telescopic block 13, the outer wall of the telescopic block 13 is embedded with a lifting block 14, the outer wall of the lifting block 14 is fixedly connected to a working frame 15, the inner wall of the working frame 15 is fixedly connected to a pneumatic push cylinder 16, the output end of the pneumatic push cylinder 16 is fixedly connected to an ejector base 17, the top of the ejector base 17 extends to the top of the lower mold core 3 and is fixedly connected to an ejector body 18, and the connecting portion of the ejector base 17 and the working frame 15 is fixedly connected to an ejector spring 19.

[0035] In this embodiment, the staff rotates the adjusting bolt 11, and the adjusting bolt 11 rotates to drive the telescopic block 13 on the outer wall of the connecting plate 12 to slide through the thread. The telescopic block 13 slides through the inclined surface to drive the working frame 15 on the outer wall of the lifting block 14 to slide vertically, and the height of the ejector body 18 at the top of the working frame 15 is adjusted to avoid the top of the ejector body 18 and the lower mold core 3 being at different heights, resulting in an uneven outer wall of the injection molding. Then, the pneumatic push cylinder 16 works to drive the ejector body 18 at the top of the ejector base 17 to slide vertically, and the ejector body 18 moves to eject the injection molded part out of the lower mold core 3, thereby realizing the unloading operation of the injection molded part.

[0036] In one embodiment, the connection portion between the telescopic block 13 and the lifting block 14 is inclined.

[0037] In this embodiment, the connection part between the telescopic block 13 and the lifting block 14 is arranged to be inclined, so that the telescopic block 13 can slide through the inclined surface to drive the working frame 15 on the outer wall of the lifting block 14 to slide vertically.

[0038] In one embodiment, the working frame 15 forms a telescopic structure with the ejector frame 10 through the telescopic block 13 and the lifting block 14 .

[0039] In this embodiment, the telescopic block 13 slides through the inclined surface to drive the working frame 15 on the outer wall of the lifting block 14 to slide vertically, and the height of the ejector body 18 at the top of the working frame 15 is adjusted to avoid the top of the ejector body 18 being at a different height from the lower mold core 3, resulting in an uneven outer wall of the injection molding.

[0041] In this embodiment, the ejector bodies 18 are arranged in an array, which facilitates the movement of the ejector bodies 18 to stably eject the injection molded part out of the lower mold core 3 .

[0042] When the mechanical mold quick separation structure of this embodiment is in use, first, the lower mold core 3 and the upper mold core 801 are quickly installed. The staff slides the lower mold 2 along the top of the lower base 1, and then turns the lower bolt 4 to fix the lower mold 2 to the top of the lower base 1 through the thread, thereby realizing the quick installation operation of the lower mold core 3 at the top of the lower mold 2. Similarly, the staff slides the upper mold 8 along the bottom of the upper base 6, and then turns the upper bolt 9 to fix the upper mold 8 to the bottom of the upper base 6 through the thread, thereby realizing the quick installation operation of the upper mold core 801 at the bottom of the upper mold 8.

[0043] Next, the staff slides the lower base 1 along the outer wall of the limiting column 5 to allow the upper mold core 801 and the lower mold core 3 to be molded together, and then performs injection molding on the cavity between the upper mold core 801 and the lower mold core 3 through the gate 7.

[0044] Finally, after injection molding, the injection molding needs to be unloaded. The staff turns the adjusting bolt 11. The adjusting bolt 11 rotates to drive the telescopic block 13 on the outer wall of the connecting plate 12 to slide through the thread. The telescopic block 13 slides through the inclined surface to drive the working frame 15 on the outer wall of the lifting block 14 to slide vertically. The height of the ejector body 18 at the top of the working frame 15 is adjusted to avoid the top of the ejector body 18 and the lower mold core 3 being at different heights, resulting in an uneven outer wall of the injection molding. Then, the pneumatic push cylinder 16 works to drive the ejector body 18 at the top of the ejector base 17 to slide vertically. The ejector body 18 moves to eject the injection molded part out of the lower mold core 3, thereby realizing the unloading operation of the injection molded part.
