To enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not a limitation of the present disclosure.

[0030] All terms used in this disclosure (including technical or scientific terms) have the same meanings as understood by those of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense, unless specifically defined as such herein.

[0031] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said techniques, methods, and devices should be regarded as part of the specification.

[0032] A brief description of the terms used in this application is as follows. Herein, both "proximal" and "distal" are relative to the observer. For example, "proximal" refers to the side closer to the observer. In contrast, "distal" refers to the side farther from the observer.

[0033] On the one hand, in combination with Figure 2 and Figure 3 , a demolding mechanism for automatically demolding the pole post product in a mold, which includes: two pairs of transmission rods 2; the transmission rods 2 are arranged in parallel; a plurality of sliders 1; the sliders 1 are respectively sleeved at both ends of the transmission rods 2; the sliders 1 on the same end of each pair of transmission rods 2 are arranged oppositely and have an interval space; a threaded pin 6, one end of which is configured to be clamped in the interval space, and the other end of which is connected to the pole post product; in the demolding state, the two transmission rods 2 of each pair rotate in opposite directions, the transmission rods 2 drive the sliders 1 to rotate, and push the threaded pin 6 through the sliders 1 to demold the pole post product. Through the above arrangement, the pole post product can be automatically demolded without manual participation.

[0034] In one embodiment, in combination with Figures 2 to 6 , the slider 1 is configured as a convex ring; a through groove 3 is formed at the edge of the convex ring; the convex rings on the same end of each pair of transmission rods 2 form the interval space in a state where the through grooves 3 are opposite to each other as the respective transmission rods 2 rotate; a snap ring portion 8 is provided at the end of the threaded pin 6; the snap ring portion 8 extends outward in the transverse direction from the end of the threaded pin 6; the snap ring portion 8 is configured to be clamped in the interval space. In this embodiment, the threaded pin 6 is clamped in the interval space through the snap ring portion 8, and in the demolding state, the transmission rods 2 drive the sliders 1 to rotate, and push the snap ring portion 8 of the threaded pin 6 through the through groove 3 of the slider 1 to demold the pole post product. In this embodiment, based on the same principle, in the mold loading state, the transmission rods 2 can also rotate in the opposite direction to that in the demolding state, and then pull the snap ring portion 8 of the threaded pin 6 to move the threaded pin 6 in the opposite direction.

[0035] In one embodiment, referring to Figure 3, the demolding mechanism further includes a limit block 4; the limit block 4 is provided with a pair of through holes corresponding to each pair of transmission rods 2, and is sleeved on the transmission rod 2 through the through holes. By providing the limit block 4, the positional relationship between adjacent transmission rods 2 is further defined, thereby ensuring the cooperation relationship between the snap ring portion 8 of the threaded pin 6 and the through groove 3 of the dial block 1.

[0036] In one embodiment, in combination with Figures 2 to 4 , limit blocks 4 are respectively arranged on both sides of each convex ring. By this setting method, during the movement of the threaded pin 6, deviation is avoided.

[0037] In one embodiment, in combination with Figures 3 to 6 , the surface of the limit block 4 on the side facing the snap ring portion 8 is set as an arc surface to match the shape of the snap ring portion 8. In this embodiment, the arc surface is set as a convex surface so that when the transmission rod 2 rotates, the same spacing is maintained in the relative state of the through groove 3 to form the interval space, thereby avoiding the radial swing of the threaded pin 6, and further ensuring the quality of the pole column product during the demolding process. In addition, in this embodiment, the bottom of the through groove 3 can also be set as a plane or a concave surface, which is not specifically limited.

[0038] On the other hand, a mold, in combination with Figure 1 and Figure 2 , includes the demolding mechanism; the mold further includes a body 5 and a driving mechanism 7 connected to each other; the body 5 is provided with a cavity; the pole column product is located in the cavity; the demolding mechanism is arranged on the near side of the body 5 and is connected to the driving mechanism 7 through the transmission rod 2; one end of the threaded pin 6 extends into the cavity and is connected to the pole column product; in the demolding state, the driving mechanism 7 drives the dial block 1 to rotate through the transmission rod 2, and pushes the threaded pin 6 through the dial block 1 to eject the pole column product. In this embodiment, in the mold loading state, according to the same principle, the transmission rod 2 rotates in the opposite direction to that in the demolding state, thereby pulling the snap ring portion 8 of the threaded pin 6 and moving the threaded pin 6 in the opposite direction to that in the demolding state, so that the cavity returns to the same state as when injecting the pole column product to be molded. It can be seen that through this embodiment, automatic operation is realized during both the demolding and mold loading processes, avoiding manual participation, thereby improving work efficiency and correspondingly avoiding factors that affect product quality due to manual participation.

[0039] In one embodiment, referring to Figure 1 , the mold further includes a fixing block 9; the fixing block 9 is fixedly arranged on the body 5; the driving mechanism 7 is connected to the body 5 through the fixing block 9. By this setting method, the stability of the driving mechanism 7 during the power transmission process is improved.

[0040] In one embodiment, in combination with Figure 4 and Figure 7, the mold further includes a gear assembly; the transmission rod 2 is connected to the driving mechanism 7 through the gear assembly; the gear assembly includes a tooth portion 10 and a pin shaft 11 that are rotatably connected to each other; the tooth portion 10 is fixedly connected to the end of the transmission rod 2 near it respectively; the pin shaft 11 is connected to the driving mechanism 7; in the demolding state, the pin shaft 11 is driven, and the tooth portion 10 drives each pair of transmission rods 2 to rotate in opposite directions.

[0041] In one embodiment, referring to Figure 7 , the driving mechanism 7 is a hydraulic mechanism including a transmission arm 14; the pin shaft 11 is arranged on the transmission arm 14. In this embodiment, specifically referring to Figure 7 , the pin shaft 11 is correspondingly arranged on both sides of the axis connection line of adjacent transmission rods 2. When the transmission arm 14 moves along the direction of the axis connection line, the pin shaft 11 pushes the adjacent tooth portions 10, and makes the adjacent tooth portions 10 rotate in opposite directions around the corresponding pin shaft 11, thereby ensuring that the adjacent transmission rods 2 rotate in opposite directions, and cooperate to push or pull the threaded pin 6 to complete the demolding and mold loading processes.

[0042] In one embodiment, the mold further includes a stationary mold 12 and a movable mold 13; the stationary mold 12 and the movable mold 13 are respectively connected to the body 5 from the near side and the far side to form a mold closure with the body 5. Through this setting method, they jointly form a mold, and thus can manufacture a pole product that meets the design through mold loading and demolding.
