The control inclined groove 211 is slidably connected to the boss 212, and the vertical plate 207 is slidably connected to the middle plate 208. The control inclined groove 211 includes a horizontal groove and an oblique groove. When the horizontal groove is close to the top column 221 and the boss 212 moves to the corner of the horizontal groove and the oblique groove, the blocking column 216 no longer fits the mold slot block 104. A pair of bosses 212 are symmetrically distributed on a vertical plate 207, and the control plate 210 is also provided with a pair corresponding to the bosses 212.

[0031] A top column 221 is fixedly installed in the middle of the middle plate 208. The top column 221 slides through the lifting plate 213 and the mold main board 1 and is inserted into the center of the mold slot block 104. A through hole 220 is opened in the middle of the lifting plate 213, and the through hole 220 is slidably connected to the top column 221; the top of the top column 221 is also provided with the external texture required for the product. The top texture of the top column 221 and the inner texture of the four mold slot blocks 104 together constitute the texture designed on the outside of the product.

[0032] A number of slots 217 are evenly arranged on the inner edge of the inner groove 101, and the slots 217 are plugged into the blocking posts 216, which fit the mold slot block 104 and the inner wall of the inner groove 101; the blocking posts 216 can provide support for the outer side of the mold slot block 104 during production and processing, and the top of the blocking posts 216 is provided with a slope, which will squeeze the mold slot block 104 to move and fit each other when moving upward.

[0035] Working principle: Before using this mold with ejection structure, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, after the mold is cold-pressed, the double-headed motor 201 is first started to rotate the double-headed threaded rod 202, thereby causing the threaded sleeve 203 to move from the middle of the double-headed threaded rod 202 to both sides, and then driving the vertical plate 207 to move outward from the middle through the side extension plate 204 and the sliding sleeve 206;

[0036] At this time, the vertical plate 207 will first drive the boss 212 to slide in the horizontal groove of the control inclined groove 211. At the same time, the control slide 209 moves along the inclined rail 215, causing the lifting plate 213 to first descend and the blocking post 216 to disengage from the slot 217. After the boss 212 has completely passed through the horizontal groove and the blocking post 216 no longer fits the mold slot block 104, the tension spring 219 will pull the mold slot block 104 to slide outward in the inclined groove 218, and the four mold slot blocks 104 will separate from each other and detach from the product.

[0037] After the protruding column 212 slides into the oblique groove of the control oblique groove 211, it squeezes the control plate 210 to move the middle plate 208 upward, and causes the top column 221 to push the product upward, making it easier to take out without damaging the outer texture of the product.

[0038] When the four mold slots 104 cannot be pulled apart by the tension springs 219, the push pins 221 push the product. Due to the curved surface of the outer grain of the product, the mold slots 104 move outward to avoid the pressure on the product grain caused by the mold slots 104 always in close contact with the product, thus reducing damage to the outer grain of the product.

[0039] Initially, the stopper 216 is located inside the inner groove 101, so that the mold slot block 104 has a stable support on the outside during production.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
