Description

Technical Field

[0001] The utility model relates to the technical field of microneedle molds, and particularly relates to a demolding mechanism for a microneedle mold. Background Art

[0002] Medical microneedles are mostly made using microneedle molds, and among them, the microneedle molds are made by silicone mold replication.

[0003] Since the size of the microneedles is small, after the microneedles are formed in the silicone microneedle mold, workers need to use tools such as tweezers to separate the microneedles from the mold. When the tweezers move between the microneedles and the mold, the tips of the tweezers will scratch the microneedles or the mold, affecting the next use of the microneedle mold.

[0004] Therefore, the traditional microneedle mold can be improved to be equipped with a demolding mechanism to facilitate the separation of the microneedles from the mold. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a demolding mechanism for a microneedle mold to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A demolding mechanism for a microneedle mold includes a mold body. A groove is formed on the outer wall of the mold body, and a pull rod is fixed in the groove. A corrugated incision is formed on the mold body, and a fitting is provided on the mold body to align the mold body on both sides of the corrugated incision.

[0008] Preferably, the fitting includes a slot formed on the mold body, and the corrugated incision is located at the slot. A clamping groove is formed on the mold body and extends into the slot. A connecting block is clamped at the slot, and a clamping block fixed to the connecting block is engaged with the clamping groove.

[0009] Preferably, a connecting hole is formed on the clamping block, and a through hole adapted to the connecting hole is formed on the mold body. A screw rod is slidably connected to the connecting hole, and the end of the screw rod is threadedly connected to the through hole.

[0010] Preferably, the screw rod is slidably connected to the through hole. When one end of the screw rod is flush with the inner side wall of the mold body, the other end of the screw rod protrudes from the outer side wall of the mold body.

[0011] Preferably, the end of the pull rod protrudes from the outer side wall of the mold body.

[0012] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are as follows:

[0013] 1. In this application, since the mold body has a certain elasticity, the mold body can be deformed by applying force to the pull rod, while the micro - needles formed within the mold body will not deform. Thus, the demolding effect between the mold body and the micro - needles is achieved. With the cooperation of the corrugated cut, the mold body can be deformed when force is applied, facilitating a larger - area demolding effect between the mold body and the micro - needles. Therefore, when the micro - needles are removed from the mold body using tweezers later, the tweezers will not come into forceful contact with the micro - needles or the mold, preventing damage to the micro - needles or the mold body.

[0014] 2. With the cooperation of the clamping blocks in this application, the alignment effect of the mold body at the corrugated cut can be achieved, ensuring that there is no deviation in the mold body on both sides of the corrugated cut. After the screw rod and the through - hole are connected by threads, the alignment of the mold body on both sides of the corrugated cut can be adjusted by controlling the screw rod, making the manufactured micro - needles more regular.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention. Embodiment

[0021] The present invention provides a technical solution. Please refer to Figures 1-3 :

[0022] A demolding mechanism for a microneedle mold, including a mold body 1. A groove 2 is formed on the outer wall of the mold body 1, and a pull rod 3 is fixed in the groove 2. The end of the pull rod 3 protrudes from the outer side wall of the mold body 1. A corrugated cut 5 is formed on the mold body 1, and a fitting is provided on the mold body 1 to align the mold body 1 on both sides of the corrugated cut 5. Since the mold body 1 is made of silica gel material and has a certain elasticity, the mold body 1 can be deformed by applying force to the pull rod 3. The microneedles formed in the mold body 1 will not deform, so as to achieve the demolding effect between the mold body 1 and the microneedles. With the cooperation of the corrugated cut 5, the mold body 1 can be deformed by force, which is convenient for a larger area demolding effect between the mold body 1 and the microneedles. Embodiment

[0023] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 3 shown, the fitting includes a slot 4 formed on the mold body 1, and the corrugated cut 5 is located at the slot 4. A clamping slot 6 is formed on the mold body 1, and the clamping slot 6 extends into the slot 4. A connecting block 8 is clamped at the slot 4, and a clamping block 9 that is clamped with the clamping slot 6 is fixed on the connecting block 8. After the connecting block 8 is clamped with the slot 4, it can support the mold body 1 at the corrugated cut 5, and it is also convenient for the mold body 1 at the corrugated cut 5 to fit with the connecting block 8, so that the mold body 1 on both sides of the corrugated cut 5 remains aligned. Therefore, the microneedles made by this mold are more regular.

[0024] A connecting hole 10 is formed on the clamping block 9, and a through hole 7 adapted to the connecting hole 10 is formed on the mold body 1. A screw rod 11 is slidably connected at the connecting hole 10, and the end of the screw rod 11 is threadedly connected with the through hole 7. The screw rod 11 is slidably connected with the through hole 7, and when one end of the screw rod 11 is flush with the inner side wall of the mold body 1, the other end of the screw rod 11 protrudes from the outer side wall of the mold body 1 at this time.

[0025] With the cooperation of the clamping block 9, it can achieve the alignment effect of the mold body 1 at the corrugated cut 5, so that the mold body 1 on both sides of the corrugated cut 5 will not show deviation. After the screw rod 11 is threadedly connected with the through hole 7, the alignment of the mold body 1 on both sides of the corrugated cut 5 can be adjusted by controlling the screw rod 11, and the operation is more convenient. Embodiment

[0026] In summary, when the microneedles are demolded in this embodiment:

[0027] Pull the screw 11 to separate the mold body 1 and the microneedle near the corrugated cut 5, and then rotate the screw 11 to remove the screw 11 from the mold body 1. Remove the connecting block 8 from the slot 4, and then pull the pull rod 3 to separate the mold body 1 and the microneedle near the pull rod 3. Finally, the mold body 1 can be bent, and with the cooperation of the corrugated cut 5, the mold body 1 is deformed, so that the mold body 1 and the microneedle have a larger area for demolding, and the staff can use tweezers to remove the microneedle from the mold body 1.

[0028] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
