Description

Technical Field

[0001] The utility model relates to the technical field of microneedle molds, in particular to a forming device for microneedle molds. Background Art

[0002] During the production of microneedle molds, it is necessary to perform silicone mold flipping on the master mold to obtain the microneedle molds.

[0003] However, during the mold flipping process, although a release agent is applied to the inner surface of the master mold, it can effectively prevent the sub-mold from adhering tightly to the master mold. However, during the subsequent demolding process, due to the elasticity of silicone, the connection between the sub-mold and the master mold after silicone molding is relatively tight. When using tools to separate the sub-mold from the master mold, it is easy to damage the edge of the sub-mold.

[0004] Therefore, it is necessary to improve the master mold of the traditional microneedle mold to make it easier to separate the microneedle mold from the master mold. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a forming device for microneedle molds in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A forming device for microneedle molds includes a mold body, symmetrically distributed openings are formed on the mold body, and baffles are attached to the openings. Fixing blocks that are in contact with the inner wall of the mold body are fixed on the baffles. A clamping groove is formed on the inner bottom wall of the mold body, and a clamping block that is engaged with the clamping groove is fixed at the bottom of the baffle. A fixing member for fixing the baffle is provided on the mold body.

[0008] Preferably, the fixing member includes a notch formed on the baffle, a square block is in contact with the outer wall of the mold body, and a bolt block that is engaged with the notch is fixed on the square block. A side block is fixed on the square block, and a side groove that is engaged with the side block is formed on the mold body.

[0009] Preferably, grooves are formed on the square block and the bolt block, and an elastic binding band is in contact with the grooves. The elastic force of the elastic binding band pushes the baffle to be in contact with the mold body.

[0010] Preferably, a sealing ring is provided on the part of the baffle that is in contact with the mold body, and a release agent is applied to both the baffle and the sealing ring to prevent the silicone from bonding to them as a whole.

[0011] Preferably, rubber gaskets are provided on the parts of the square block and the bolt block that are in contact with 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, by removing the elastic strap and detaching the square block from the mold body, the baffle can be pulled out upwards. Then, the staff can extract the silicone microneedle mold from the mold body through the opening. This operation is relatively convenient, enabling the staff to directly apply force to the microneedle mold, thus causing the microneedle mold to separate from the mold body. This effectively avoids damage to the part of the outer wall of the microneedle mold that comes into contact with the mold body during demolding.

[0014] 2. In this application, under the action of the bolt block, the baffle can be connected to the mold body as a whole, that is, the baffle cannot move in the vertical and horizontal directions. Therefore, the baffle and the mold body can form a complete mold, facilitating the staff to perform the mold turning operation. BRIEF DESCRIPTION OF THE DRAWINGS

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

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

[0022] A forming device for a microneedle mold, including a mold body 1, symmetrically distributed openings 2 are provided on the mold body 1, and a baffle 5 is attached to the openings 2. A fixing block 6 that abuts against the inner wall of the mold body 1 is fixed on the baffle 5. A clamping groove 3 is provided on the inner bottom wall of the mold body 1, and a clamping block 7 that is engaged with the clamping groove 3 is fixed at the bottom of the baffle 5. A fixing member for fixing the baffle 5 is provided on the mold body 1. A sealing ring is provided on the part of the baffle 5 in contact with the mold body 1, and a release agent is applied to both the baffle 5 and the sealing ring to prevent the silicone from bonding to it as a whole. Embodiment

[0023] It is basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 3 shown, the fixing member includes a notch 8 provided on the baffle 5, and a square block 9 abuts against the outer wall of the mold body 1, and a bolt block 10 that is engaged with the notch 8 is fixed on the square block 9. A side block 11 is fixed on the square block 9, and a side groove 4 that is engaged with the side block 11 is provided on the mold body 1. Grooves 12 are provided on the square block 9 and the bolt block 10, and an elastic strap 13 abuts against the grooves 12. The elastic force of the elastic strap 13 pushes the baffle 5 to abut against the mold body 1.

[0024] Under the elastic force of the elastic strap 13, the baffle 5 can stably close the opening 2 of the mold body 1. Therefore, the mold body 1 at this time becomes a complete master mold for silicone casting of the microneedle mold. Rubber gaskets are provided on the parts of the square block 9 and the bolt block 10 in contact with the mold body 1. Therefore, the square block 9 and the bolt block 10 will not cause wear when they contact the mold body 1.

[0025] In summary, when making a microneedle mold provided in this embodiment, place the baffle 5 at the opening 2 of the mold body 1, and the clamping block 7 at the bottom of the baffle 5 is engaged with the clamping groove 3 provided on the mold body 1. Then the fixing block 6 abuts against the inner wall of the mold body 1.

[0026] Attach the square block 9 to the outer wall of the mold body 1, and the side block 11 at one end of the square block 9 is engaged with the side groove 4 on the outer wall of the mold body 1. The bolt block 10 at the other end of the square block 9 is engaged with the notch 8. The baffle 5 is fixed to the mold body 1 at this time. Put the elastic strap 13 on the grooves 12 provided on the square block 9 and the bolt block 10. Under the elastic force of the elastic strap 13, the baffle 5 is closely attached to the mold body 1, so that the gap between the baffle 5 and the mold body 1 can be effectively prevented.

[0027] Subsequently, a release agent can be applied to the inside of the mold body 1, and then the silicone is poured into the mold body 1 and wait for the silicone to cure and form.

[0028] After the silicone is formed into a microneedle mold, the elastic strap 13 can be removed at this time, the square block 9 can be removed from the mold body 1, and then the baffle 5 can be pulled out upward. The staff can then extract the silicone microneedle mold from the mold body 1 through the opening 2.

[0029] The foregoing description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
