[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0029] Combination Figure 1 , Figure 2 , Figure 3 and Figure 5 A mold for producing medical device shells with rapid ejection capability includes a fixed frame 1 and a connecting frame 2 fixedly connected to the top of the fixed frame 1. A lower mold 11 is slidably connected to the top of the fixed frame 1, and a telescopic cylinder 12 is fixedly connected to the top of the connecting frame 2. The top of the fixed frame 1 is also provided with a placement groove 13, and two sets of placement grooves 13 are provided. A sliding block 111 is slidably connected inside the fixed frame 1, and a spring rod 112 is fixedly connected inside the sliding block 111. One end of the spring rod 112 is fixedly connected to a push plate 113, which is slidably connected inside the lower mold 11. The fixed frame 1 is provided with a moving mechanism for adjusting the position of the lower mold 11 to facilitate the ejection operation of the workpiece by the operator. A push cylinder 131 is fixedly connected inside the placement groove 13, and an ejection block 132 is fixedly connected to the output end of the push cylinder 131.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example 1:

[0032] To address the problem that most existing medical device housing molds have a simple structure and often lack a stable ejection mechanism, leading to workpiece deformation during ejection and hindering their use, this embodiment discloses the following technical solution, specifically as follows: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the moving mechanism includes a motor 14 fixedly connected inside the fixed frame 1, and a lead screw 141 fixedly connected to the output end of the motor 14. A sliding block 111 is threadedly connected to the lead screw 141. During use, the workpiece to be processed can be placed inside the lower mold 11. After placement, the telescopic cylinder 12 can be activated, causing the connecting plate 21 to move, which in turn moves the upper mold 22. The movement of the upper mold 22, in conjunction with the lower mold 11, presses the workpiece, thus shaping it. When demolding is required, the motor 14 can be activated, causing the lead screw 141 to rotate, which in turn moves the sliding block 111. 1. The lower mold 11 is moved, causing it to move away from below the connecting frame 2 and move to the top of the placement groove 13. At this time, the push cylinder 131 can be activated, which drives the ejector block 132 to move, causing the ejector block 132 to move out of the placement groove 13. The ejector block 132 can contact the push plate 113, causing the push plate 113 to rise. This facilitates demolding operations for the operator. When it is necessary to reset the lower mold 11, the push plate 113 is reset under the action of the spring rod 112, and the lower mold 11 can be used normally. This realizes the function of facilitating demolding operations for the operator and improves the usage effect.

[0033] To address the issue that existing medical device shell molds are often integrated, making it difficult to replace the mold when dealing with different workpieces and affecting usability, this embodiment also discloses the following solution: A connecting plate 21 is fixedly connected to the output end of the telescopic cylinder 12. An upper mold 22 is detachably mounted on the bottom of the connecting plate 21. A knob 211 is rotatably connected to one side of the connecting plate 21. A lead screw 212 is fixedly connected to one end of the knob 211. A locking block 213 is threaded onto the outer side of the lead screw 212 and slidably connected inside the connecting plate 21. A protrusion 221 is fixedly connected to the top of the upper mold 22, and a slot 222 is provided through the protrusion 221. The slot 222 and the locking block 213 slide together. When it is necessary to change the upper mold 22, the knob 211 on the connecting plate 21 can be rotated. The knob 211 drives the lead screw 212 to rotate, thereby moving the locking block 213 and causing it to disengage from the slot 222 on the protrusion 221. At this time, the upper mold 22 can be moved out from the bottom of the connecting plate 21. When installing, the upper mold 22 can be placed back in its original position, and then the knob 211 can be rotated in the opposite direction to make the locking block 213 re-lock into the protrusion 221. This completes the installation of different templates and enables the staff to easily change the upper mold 22 according to different workpieces.

[0034] Example 2:

[0035] This embodiment discloses another movement method, which differs from Embodiment 1 and facilitates demolding operations for workers. Please refer to [link / reference needed] for details. Figure 3 The moving mechanism includes a knob 15 rotatably connected to one side of the fixed frame 1, and a bevel gear 151 fixedly connected to one end of the knob 15. A bevel gear 152 is meshed with one side of the bevel gear 151. The bevel gear 152 is rotatably connected inside the fixed frame 1. A lead screw 153 is fixedly connected to one side of the bevel gear 152. The lead screw 153 is threadedly connected to the sliding block 111. When it is necessary to move the lower mold 11 to make the demolding operation more convenient, the knob 15 located on one side of the fixed frame 1 can be rotated. The knob 15 drives the bevel gear 151 to rotate, which in turn causes the bevel gear 152 to rotate. The bevel gear 152 drives the lead screw 153 to rotate, which in turn causes the sliding block 111 to slide inside the fixed frame 1. At this time, the lower mold 11 can be positioned above the placement groove 13, and the push cylinder 131 can be activated to perform the demolding operation.

[0036] Example 3:

[0037] This embodiment discloses another fixing method, which differs from Embodiments 1 and 2, and facilitates demolding operations for workers. Please refer to the following for details. Figure 4 The moving mechanism includes a magnetic suction plate 16 fixedly connected inside the fixed frame 1, and a sliding block 111 made of magnetic material. A fixed handle 161 is fixedly connected to one side of the sliding block 111, and one end of the fixed handle 161 extends to the outside of the fixed frame 1. When it is necessary to move the lower mold 11 to make the demolding operation more convenient, the fixed handle 161 can be grasped. The fixed handle 161 drives the sliding block 111 to move, thereby making the sliding block 111 fit with the magnetic suction plate 16. At this time, the lower mold 11 can be placed above the placement groove 13, and the pushing cylinder 131 can be activated to perform the demolding operation.
