[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a mold blank for hardware parts that is easy to open and close. It mainly consists of an upper mold blank 1, a lower mold blank 2, and a locking component 3. This enables the mold blank for hardware parts to be easy to open and close, while ensuring the stability and reliability of the mold during use, thereby improving the molding quality and production efficiency of hardware parts.

[0026] The upper end face of the lower mold blank 2 is provided with a downwardly recessed trapezoidal groove 201, and a lower groove 202 is formed in the middle of the trapezoidal groove 201. The lower end face of the upper mold blank 1 is provided with a trapezoidal platform 101 that matches the trapezoidal groove 201, and an upper groove 102 that communicates with the lower groove 202 is formed at the corresponding position of the trapezoidal platform 101. In the actual assembly process, the trapezoidal platform 101 of the upper mold blank 1 is aligned with the trapezoidal groove 201 of the lower mold blank 2, so that the two fit together, and the upper groove 102 and the lower groove 202 are also connected to form a complete cavity structure. This cavity structure can be used for the molding of hardware parts. Through the cooperation of the trapezoidal platform 101 and the trapezoidal groove 201, the upper and lower mold blanks can be initially positioned to ensure the stability of the mold during use.

[0027] The upper end face of the lower mold blank 2 is also provided with several locking slots 203 distributed around the trapezoidal grooves 201. The inner wall of each locking slot 203 is provided with an insertion hole 204 that communicates with the outer side of the lower mold blank 2. The lower end face of the upper mold blank 1 is provided with several locking rods 103 that can be inserted into the corresponding locking slots 203. The side of the locking rods 103 is provided with locking holes 104 that correspond to the insertion holes 204. The outer side of the lower mold blank 2 is provided with a locking member 3 that passes through the insertion holes 204 and is fixed to the locking holes 104 by a threaded body. After the trapezoidal platform 101 and the trapezoidal groove 201 are initially fitted together, the locking rod 103 is inserted into the locking slot 203. At this time, by rotating the locking member 3, the threaded part of the locking member 3 passes through the insertion hole 204 and is screwed into the locking hole 104, thereby firmly locking the upper mold blank 1 and the lower mold blank 2 together, ensuring that the upper and lower mold blanks will not be relatively displaced during the forming process of the hardware parts, thus ensuring the forming accuracy of the hardware parts.

[0028] The outer side of the lower mold blank 2 is provided with a receiving groove 207 for accommodating the locking member 3. The locking member 3 includes a fixing part 301 disposed in the receiving groove 207, a locking part 302 passing through the insertion hole 204 and connected to the locking hole 104, and a twisting part 303 for controlling rotation. The locking part 302 is connected to one side of the fixing part 301, and the twisting part 303 is connected to the other end of the fixing part 301 and protrudes upward. The arrangement of the receiving groove 207 allows the locking member 3 to be hidden on the outer side of the lower mold blank 2 during use, avoiding the risk of interference or damage caused by the locking member 3 protruding from the surface of the lower mold blank 2. When it is necessary to lock the upper and lower mold blanks, the rotating twisting part 303 drives the fixing part 301 and the locking part 302 to rotate, so that the locking part 302 passes through the insertion hole 204 and screws into the locking hole 104; when it is necessary to open the upper and lower mold blanks, the rotating twisting part 303 is rotated in the opposite direction, and the locking part 3 can be screwed out from the locking hole 104. The operation is simple and convenient.

[0029] Furthermore, the outer side of the locking rod 103 is provided with two parallel upper planes 105, and the insertion hole 204 is opened and connected between the two upper planes 105; the inner wall of the locking slot 203 is provided with two parallel lower planes 205, the position of the lower planes 205 corresponding to the upper planes 105, and the insertion hole 204 is opened on one of the lower planes 205. This structural design allows the upper planes 105 and lower planes 205 to fit together during the insertion process of the locking rod 103 and the locking slot 203, which plays a better role in positioning and guiding, and also facilitates the insertion and tightening operation of the locking part 3, thereby improving assembly efficiency.

[0030] To further facilitate the assembly of the upper mold blank 1 and the lower mold blank 2, a tapered guide surface 206 is coaxially provided on the inner wall of the opening end of the locking slot 203. The diameter of the guide surface 206 gradually increases along the insertion direction. When the locking rod 103 is inserted into the locking slot 203, the tapered guide surface 206 guides the locking rod 103, allowing it to be inserted into the locking slot 203 more smoothly, reducing assembly difficulty and improving assembly convenience.

[0031] In this embodiment, the trapezoidal platform 101 has a circular trapezoidal structure, and the locking rods 103 are equidistantly distributed around the periphery of the trapezoidal platform 101. The circular trapezoidal platform 101, in conjunction with the trapezoidal groove 201, provides a more uniform force distribution, improving the stability and service life of the mold. The equidistant distribution of the locking rods 103 ensures that the upper mold blank 1 and the lower mold blank 2 experience more uniform force during locking, further guaranteeing the reliability of the mold during use.

[0032] Compared with traditional technologies, the hardware parts mold blanks provided in this solution, through the matching structure of the trapezoidal groove 201 of the lower mold blank 2 and the trapezoidal platform 101 of the upper mold blank 1, can achieve rapid and accurate preliminary positioning of the upper and lower mold blanks. This ensures that the relative positions of the upper and lower mold blanks in the horizontal direction are accurate during mold assembly, and it is not easy to shift, which greatly reduces the assembly difficulty and improves the assembly efficiency. Through the combination structure of the locking slot 203 and insertion hole 204 set in the lower mold blank 2, together with the locking rod 103, locking hole 104 and locking element 3 of the upper mold blank 1, the upper and lower mold blanks can be quickly locked and separated. The operation process is simple and convenient, which greatly shortens the mold opening and closing time and improves production efficiency.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
