[0012] 1. In the utility model, an auxiliary device is provided. When the device is needed, the pull rod is pulled first, and the movement of the pull rod drives the upper mold to move. The movement of the upper mold drives the slide plate to move on the surface of the vertical pole. The movement of the slide plate on the surface of the vertical pole drives the first spring to stretch. When the upper mold moves to a suitable position, the silicone strip is placed on the convex mold. After the placement is completed, the pull rod is released, and the resilience of the first spring is used to complete the mold closing operation between the upper mold and the lower mold. Then, the upper mold and the lower mold are placed in a plate pressing machine for heating and pressurization. After a few minutes, the upper mold and the lower mold are taken out from the plate pressing machine. After taking them out, the moving plate is slid downward to move the moving plate inside the vertical groove. The movement of the moving plate inside the vertical groove squeezes the second spring, so that the first spring The second spring is compressed by force, and at the same time, the moving plate moves inside the vertical groove and also drives the insertion rod to move. The movement of the insertion rod makes it move out from the inside of the through hole, and the separation of the insertion rod and the through hole makes the pull plate lose its limit. At this time, the pull rod is pulled upward, so that the pull rod drives the upper mold to move, and the upper mold and the lower mold are separated. When the upper mold moves to a suitable height, the pull plate is pulled at this time, and the movement of the pull plate drives the sliding plate to move inside the sliding groove. The movement of the sliding plate inside the sliding groove drives the connecting rod to move, and the movement of the connecting rod drives the raised mold to move. When the raised mold moves out of the lower mold by a certain distance, the mobile phone case stuck to the raised mold can be conveniently removed. Through the cooperation of the above structure, it is beneficial to remove the formed mobile phone case from the raised mold, thereby improving the practicability of the device.

[0013] 2. In the utility model, by setting a scraping device, when it is necessary to remove the silicone on the mobile phone case that exceeds the edge of the raised mold, first start the electric telescopic rod, the electric telescopic rod starts to drive the movable block to move inside the strip groove, the movable block moves inside the strip groove to drive the hinge plate to move, the hinge plate moves to push the slider to move inside the long groove, and the movement of the hinge plate also drives the scraper to rotate. When the scraper rotates to a vertical state, the electric telescopic rod is closed. At this time, when the raised mold is driven to move by the pull plate, the scraper can be used to cut off the excess part of the mobile phone case manufactured by sticking to the raised mold. Through the cooperation of the above structure, the scraper can scrape off the excess waste glue generated outside the molding area, thereby improving the quality of the product after molding.

[0030] Specifically, a rectangular plate 211 is fixedly installed on the side of the lower mold 1, and a second spring 212 is fixedly installed between the rectangular plate 211 and the movable plate 208. The second spring 212 has the effect of limiting the position of the movable plate 208 inside the vertical groove 207.

[0031] In this embodiment: a scraping device 3 is provided on the surface of the lower mold 1, and the scraping device 3 includes four fixed plates 301, and the four fixed plates 301 are symmetrically distributed on the surface of the lower mold 1 in a group of two, and each group of fixed plates 301 is rotatably connected with a rotating shaft 302, and a scraper 303 is fixedly installed on the outer wall of the rotating shaft 302. When it is necessary to remove the silicone on the mobile phone case that exceeds the edge of the protruding mold 205, first start the electric telescopic rod 310. The electric telescopic rod 310 starts to drive the movable block 308 to move inside the strip groove 307. The movable block 308 moves inside the strip groove 307 to drive the hinged plate 309 to move. The movement of the hinged plate 309 pushes the slider 305 to move inside the long groove 304. At the same time, the movement of the hinged plate 309 also drives the scraper 303 to rotate. When the scraper 303 rotates to a vertical state, the electric telescopic rod 310 is closed. At this time, when the protruding mold 205 is driven to move by the pull plate 206, the scraper 303 can be used to cut off the excess part of the mobile phone case manufactured by sticking to the protruding mold 205.

[0034] Specifically, an electric telescopic rod 310 is fixedly mounted on the inner wall surface of the horizontal end of the L-shaped plate 306 , and an output end of the electric telescopic rod 310 is fixedly connected to the movable block 308 .

[0035] In this embodiment, the electric telescopic rod 310 is provided to drive the movable block 308 to move inside the strip groove 307 .

[0036] Working principle: by setting the auxiliary device 2, when the device is needed, first pull the pull rod, the movement of the pull rod drives the upper mold 7 to move, the movement of the upper mold 7 drives the slide plate 5 to move on the surface of the vertical pole 4, the movement of the slide plate 5 on the surface of the vertical pole 4 will drive the first spring 6 to stretch, when the upper mold 7 moves to a suitable position, the silicone strip is placed on the raised mold 205, after the placement is completed, release the pull rod, and use the resilience of the first spring 6 to complete the mold closing operation between the upper mold 7 and the lower mold 1, then put the upper mold 7 and the lower mold 1 into the platen press for heating and pressurization, take out the upper mold 7 and the lower mold 1 from the platen press after a few minutes, after taking them out, slide the moving plate 208 downward to make the moving plate 208 move inside the vertical groove 207, the movement of the moving plate 208 inside the vertical groove 207 will squeeze the second spring 212, so that the second spring 212 is compressed, and at the same time the moving plate 20 The movement of 8 inside the vertical groove 207 also drives the insertion rod 209 to move. The movement of the insertion rod 209 makes it move out of the inside of the through hole 210. The separation of the insertion rod 209 and the through hole 210 makes the pull plate 206 lose its limit. At this time, the pull rod is pulled upward, so that the pull rod drives the upper mold 7 to move, so that the upper mold 7 and the lower mold 1 are separated. When the upper mold 7 moves to a suitable height, the pull plate 206 is pulled at this time. The movement of the pull plate 206 drives the sliding plate 203 to move inside the slide groove 202. The movement of the sliding plate 203 inside the slide groove 202 drives the connecting rod 204 to move. The movement of the connecting rod 204 drives the protruding mold 205 to move. When the protruding mold 205 moves out of the lower mold 1 for a certain distance, the mobile phone case stuck on the protruding mold 205 can be conveniently removed. Through the cooperation of the above structure, it is beneficial to remove the formed mobile phone case from the protruding mold 205, thereby improving the practicality of the device. When it is necessary to remove the silicone on the mobile phone case that exceeds the edge of the protruding mold 205, first start the electric telescopic rod 310. The electric telescopic rod 310 starts to drive the movable block 308 to move inside the strip groove 307. The movable block 308 moves inside the strip groove 307 to drive the hinged plate 309 to move. The movement of the hinged plate 309 pushes the slider 305 to move inside the long groove 304. At the same time, the movement of the hinged plate 309 also drives the scraper 303 to rotate. When the scraper 303 rotates to a vertical state, the electric telescopic rod 310 is closed. At this time, when the protruding mold 205 is driven to move by the pull plate 206, the scraper 303 can be used to cut off the excess part of the mobile phone case manufactured by sticking to the protruding mold 205. Through the cooperation of the above structure, the scraper 303 can scrape off the excess waste glue generated outside the molding area, thereby improving the quality of the product after molding.
