A demolding mechanism is adjustablely disposed between the mold cavity and the installation cavity. The demolding mechanism includes a slide rod slidably connected to the frame. The top of the slide rod extends to the top of the relief groove and a stop seat is detachably mounted thereon. The shape and projected area of the stop seat are consistent with the shape and projected area of the relief groove. A buffer assembly is adjustablely disposed in the installation cavity and connected to the bottom of the slide rod.
[0007] Preferably, the buffer assembly includes a guide seat that is slidably connected to the mounting cavity, the guide seat being connected to the bottom end of the slide rod; a second elastic member whose top end is connected to the top end of the mounting cavity and whose bottom end is connected to the guide seat; two sets of buffer rods, the top ends of which are hinged to the bottom end of the guide seat, and the bottom ends of which are hinged to buffer blocks, the buffer blocks being slidably connected to the bottom end of the mounting cavity; and a telescopic rod installed between the two sets of buffer blocks, a third elastic member being sleeved on the outside of the telescopic rod, the third elastic member being installed between the two sets of buffer blocks.
[0008] Preferably, the lower mold consists of a mold body and a base, the base being detachably connected to the mold body by bolts, and the mounting cavity and the mold cavity being set on the mold body.
[0009] Preferably, the top of the base is provided with a sliding groove, and the buffer block is slidably connected to the sliding groove.
[0010] Preferably, the frame has a limiting groove, the base is inserted into the limiting groove, and the upper end of the side wall of the base is provided with an ear seat, which is detachably connected to the frame by bolts.
[0011] Preferably, the mounting base is provided with multiple sets of stabilizing components, each including a guide rod that slides through the edge of the mounting base; a first elastic member, one end of which is connected to the top of the guide rod and the other end of which is connected to the top of the mounting base; and a pressure seat, which is connected to the bottom end of the guide rod, with a storage cavity corresponding to the pressure seat opened at the bottom edge of the mounting base.

The detachable setting of the lower mold facilitates the disassembly and maintenance of the demolding mechanism. The setting of the stabilizing component makes it easy to keep the blank on the lower mold stable when the upper mold moves down for stamping, avoiding displacement that interferes with the stamping forming effect.

[0020] Furthermore, the buffer assembly includes a guide seat 402, a second elastic element 403, and a telescopic rod 406; the guide seat 402 is slidably connected to the mounting cavity 304, and the guide seat 402 is connected to the bottom end of the slide rod 4; the top end of the second elastic element 403 is connected to the top end of the mounting cavity 304, and the bottom end of the second elastic element 403 is connected to the guide seat 402; the second elastic element 403 is configured as a buffer spring, and the second elastic element 403 is sleeved on the outside of the slide rod 4; two sets of buffer rods 404 are provided, and the top ends of both sets of buffer rods 404 are connected to the guide seat 406. 02 The bottom ends are hinged. The bottom ends of the two sets of buffer rods 404 are hinged to buffer blocks 405. The buffer blocks 405 are slidably connected to the bottom end of the mounting cavity 304. The telescopic rod 406 is installed between the two sets of buffer blocks 405. The telescopic rod 406 is composed of a sleeve and a sleeve rod that is slidably connected to the inner wall of the sleeve. The other end of the sleeve and the sleeve rod are respectively installed on the side wall of the two sets of buffer blocks 405. A third elastic element 407 is sleeved on the outside of the telescopic rod 406. The third elastic element 407 is set as a buffer spring and is installed between the two sets of buffer blocks 405.
[0021] Furthermore, the lower mold consists of a mold body 3 and a base 301. The base 301 is detachably connected to the mold body 3 by bolts. The mounting cavity 304 and the mold cavity 302 are set on the mold body 3.
[0022] Furthermore, a groove 305 is provided at the top of the base 301, and the buffer block 405 is slidably connected to the groove 305, so that the two sets of buffer blocks 405 can slide stably along the groove 305 to move closer or further away.
[0023] Furthermore, a limiting groove 101 is provided on the frame 1, and the base 301 is inserted into the limiting groove 101. An ear seat is provided on the upper end of the side wall of the base 301, and the ear seat is detachably connected to the frame 1 by bolts.
[0024] In this embodiment, the blank of the medical device shell is placed at the top of the mold body 3. The controller activates the hydraulic rod to move the upper mold on the mounting base 2 downward until the upper mold presses the blank into the mold cavity 302 for forming. At this time, the upper mold moves the shell to press the abutment seat 401 into the relief groove 303 for storage.

At the same time, the second elastic element 403 drives the guide seat 402 to slide upward along the mounting cavity 304, thereby driving the mounting seat 2 to slide upward and the abutment seat 401 to move upward, pushing the outer shell towards the outside of the mold cavity 302, thus facilitating the demolding of the outer shell and improving processing efficiency. When the demolding mechanism needs to be repaired, the bolts between the base 301 and the frame 1 are removed, so that the lower mold is separated from the frame 1. Then the bolts between the base 301 and the mold body 3 are removed, so that the base 301 is separated from the mold body 3. Then the bolts between the abutment seat 401 and the slide rod 4 are removed, so that the demolding mechanism can be taken out of the lower mold for repair.
[0025] Example 2
[0026] like Figure 1As shown, the shell molding device proposed in this utility model, compared with the first embodiment, has multiple sets of stabilizing components on the mounting base 2. The stabilizing components include a guide rod 201, a first elastic element 202, and a pressure seat 203. The guide rod 201 is slidably disposed through the edge of the mounting base 2. One end of the first elastic element 202 is connected to the top end of the guide rod 201, and the other end is connected to the top end of the mounting base 2. The first elastic element 202 is configured as a buffer spring and is sleeved on the outside of the guide rod 201. The pressure seat 203 is connected to the bottom end of the guide rod 201, and a receiving cavity corresponding to the pressure seat 203 is opened at the bottom edge of the mounting base 2.
[0027] In this embodiment, when the hydraulic rod drives the upper mold on the mounting base 2 to move downward, the pressure seat 203 in each group of stabilizing components first contacts the raw material on the lower grinding die, and the upper mold continues to move downward, so that the guide rod 201 slides upward along the mounting base 2 and stretches the first elastic element 202 until the upper mold abuts against the mold cavity 302 in the lower grinding die. The raw material is pressed tightly onto the lower grinding die by each group of pressure seats 203, so as to avoid easy displacement during stamping and affect the stamping quality.
