[0031] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The auxiliary structure 3 includes two fixing plates 301, two fixing blocks 303, and two positioning rods 312. The two fixing plates 301 are fixedly connected to the base plate 5, the two fixing blocks 303 are fixedly connected to the lower mold 6, and the two positioning rods 312 are fixedly connected to the lower mold 6. A limiting groove 302 is formed on the inner wall of the fixing plate 301, and a connecting block 316 is slidably connected to the inner wall of the limiting groove 302. The two connecting blocks 316 are fixedly connected to the lower mold 6.

[0032] In the embodiments of this utility model, please refer to Figure 4 The feeding structure 4 includes four support columns 41, which are fixedly connected to the three-dimensional forming equipment 1. A material basket 45 is fixedly connected to the upper surface of the four support columns 41, and a support plate 42 is fixedly connected to the lower surface of the material basket 45. A cylinder 43 is fixedly connected to the upper surface of the support plate 42, and a push plate 44 is fixedly connected to the output end of the cylinder 43. An auxiliary groove 46, a placement groove 47, and a connecting groove 48 are provided on the inner wall of the material basket 45. The auxiliary groove 46 and the placement groove 47 are interconnected, and the placement groove 47 and the connecting groove 48 are interconnected. The push plate 44 is slidably connected to the auxiliary groove 46. When personnel need to place the pillow shell plate on the lower mold 6 for die casting, they can activate the cylinder 43 to move the support plate 42 towards the lower mold 6 until the pillow shell plate is moved to the appropriate position. This avoids manual feeding and improves the production efficiency of the three-dimensional forming equipment 1.

[0033] The working principle of the pillowcase three-dimensional molding device provided by this utility model is as follows: When a person needs to die-cast a pillowcase, the person places the pillowcase plate on the molding groove 7, and then activates the hot pressing device 2 to perform three-dimensional die-casting on the pillowcase plate. When the person needs to remove the molded pillowcase from the molding groove 7, the person can first move the anti-slip sleeve 315. The anti-slip sleeve 315 drives the handle 314 to move away from the hot pressing device 2. The anti-slip sleeve 315 can increase the friction between the person's hand and the handle 314, preventing the person from slipping during the movement of the handle 314. Then the handle 314 drives... The movable plate 311 moves away from the hot press device 2, driving the two auxiliary frames 310 to move away from the hot press device 2. The movable plate 311 also drives the two springs 313 and two bellows 318 to wind up. The bellows 318 protect the springs 313 from external environmental influences, thus extending their service life. Then, the auxiliary frames 310 drive one end of the connecting plate 309 away from the lower mold 6, and the connecting plate 309 drives the connecting frame 308 away from the positioning groove 319. The connecting frame 308 drives the connecting plate 304... Moving away from the positioning groove 319, the connecting plate 304 drives the limiting block 306 and guide block 305 to move away from the positioning groove 319. The guide block 305 guides the connecting plate 304, making it easier for personnel to slide the connecting plate 304 into the inner wall of the positioning groove 319. Then, the limiting block 306 drives the protective pad 307 to move closer to the fixing block 303 until the protective pad 307 abuts against the fixing block 303. At this time, the personnel continue to move the handle 314. The protective pad 307 protects the limiting block 306 and the fixing block 303, preventing them from colliding. Direct contact occurs, causing the handle 314 to move away from the hot press device 2. At this time, the connecting plate 304 will drive the fixing block 303 to move away from the hot press device 2. The two fixing blocks 303 will drive the lower mold 6 to move away from the hot press device 2. The lower mold 6 will drive the two connecting blocks 316 to move away from the hot press device 2. The connecting block 316 slides on the arc surface of the limiting rod 317. The limiting rod 317 can limit the connecting block 316 and prevent the connecting block 316 from being misaligned during the sliding process on the inner wall of the limiting groove 302, until the lower mold 6 moves away from the lower surface of the hot press device 2.

[0034] In addition, when personnel need to place the pillow shell plate on the lower mold 6 for molding and die casting, they can first slide multiple pillow shell plates into the inner wall of the placement groove 47. Then, by starting the cylinder 43, the output end of the cylinder 43 drives the push plate 44 to move closer to the lower mold 6. The push plate 44 drives the bottom pillow shell plate to move closer to the lower mold 6 until the pillow shell plate completely slides out of the inner wall of the connecting groove 48 and moves to the appropriate position. Then, the personnel restart the cylinder 43 to move the push plate 44 closer to the auxiliary groove 46 until the push plate 44 completely slides into the inner wall of the auxiliary groove 46. At this time, due to the weight of the pillow shell plate, the pillow shell plate will move downward by itself until the bottom pillow shell plate abuts against the bottom wall of the placement groove 47.

[0035] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
