Description

Technical Field

[0001] This invention belongs to the field of biomaterial molding technology, and in particular relates to a detachable bone repair material molding mold. Background Technology

[0002] Biomimetic calcium-phosphorus artificial bone is made of calcium-phosphorus material with hydroxyapatite as the phase. It has similar composition, structure and biomechanical properties to natural bone, and has good biocompatibility and in vivo safety. It is widely used in medicine.

[0003] The bone repair material uses a one-piece mold in the molding process. The main steps involve filling the mold with a mixed biomimetic calcium-phosphorus raw material and drying it. After drying, the product is removed from the mold using tools. This type of mold has the disadvantage of difficult demolding. Because the mold is one-piece, demolding is done by using tools to push the sample out of the mold, which inevitably damages the material inside the mold. In addition, because the stainless steel mold has a certain degree of roughness during the manufacturing process, and the natural polymer materials added to the combined bone repair material have a certain degree of adhesion to the stainless steel, demolding is always difficult in actual demolding.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1-3 As shown, a detachable bone repair material molding die includes a central template 1, side templates 2, positioning posts 3, and fixing components 4. The central template 1 has multiple first molding grooves 11; the side templates 2 are respectively located on both sides of the central template, and each side template has a second molding groove 21. Both the first and second molding grooves have openings; the positioning posts 3 are fixed to the side walls of the side templates, and the side walls of the central template have positioning grooves 12 for the positioning posts to be inserted; the fixing components 4 have insertion slots 41 for the side templates to be inserted. When assembling the side templates and the central template, the positioning posts are aligned with the positioning grooves, and then... Then, insert the positioning pin into the positioning groove to complete the splicing. At this time, the side wall of the side template is attached to the side wall of the middle template, and the first shaping groove and the second shaping groove can form a closed groove. Then, insert the spliced ​​side template and middle template into the insertion groove of the fastener to complete the splicing and fixing of the side template and the middle template. Then, put the biomimetic calcium phosphorus artificial bone material into the closed groove formed by the first shaping groove and the second shaping groove for shaping. After shaping, remove the fastener, and then pull the side template to both sides to remove the side template. The demolding can be easily completed.

[0031] Specifically, the fastener 4 includes a first fixed plate 41, a second fixed plate 42, and an elastic protrusion 43. The insertion groove is opened on the first fixed plate and the second fixed plate. The elastic protrusion 43 is fixed on the first fixed plate and the second fixed plate. The side template 2 is provided with a slot 22 for the elastic protrusion to be inserted into, so as to prevent the side template and the middle template from automatically falling out of the fastener and ensure the molding quality.

[0032] In other embodiments, the fixing member also includes a guide post 44 and a tension elastic member 45. The guide post 44 is fixed on the first fixing plate, and the second fixing plate is provided with a guide hole 421 for sliding with the guide post. The tension elastic member 45 is a spring, one end of which is fixed on the guide post and the other end is fixed in the guide hole. By pulling the guide post with the tension elastic member, the clamping effect of the fixing member on the center template and the side template can be guaranteed.

[0033] In other embodiments, a base plate 46 is fixed on the first fixing plate and the second fixing plate to facilitate the injection of material into the closed groove formed by the first shaping groove and the second shaping groove.

[0034] In other embodiments, a pull plate 47 is fixed on the first fixed plate and the second fixed plate, and the side template and the middle template are removed by pulling the first fixed plate; multiple anti-slip protrusions 48 are fixed on the pull plate to improve the friction of the pull plate.

[0035] In other embodiments, the insertion slot 41 is provided with an arc-shaped curved surface 411 to facilitate the insertion of the side template into the insertion slot.
