Description

Technical Field

[0001] This invention relates to the field of injection molds, and more specifically, to an injection mold for eyeglass frames. Background Technology

[0002] Currently, injection molds are required for the injection molding of eyeglass frames. Most existing eyeglass frame injection molds are designed with a dual-mold structure. In addition, the overall eyeglass frame injection mold lacks a good matching and installation structure, and the actual installation method is simple. It is not possible to carry out multi-end matching and connection installation work. When actually installing and arranging the injection mold body, its flexibility and convenience are poor.

[0003] The invention disclosed in the authorization announcement number CN 217597685 U discloses an injection mold for eyeglass frames in the field of eyeglass frame processing, including a mold body. A first mating groove is provided in the middle of the top wall of the mold body, and a second mating groove is provided on the rear side of the bottom wall of the first mating groove. Threaded holes are provided at the four corners of the top wall of the mold body. The threaded holes can be used with fixing parts to install the first mating groove and the second mating groove on the top of the mold body with the injection molding mechanism. The actual injection molding of eyeglass frames is more convenient.

[0004] The aforementioned disclosed structure uses a fixed assembly and installation method, lacking corresponding switching and combination structures. This not only makes it difficult to align the installation and prone to interference, but also makes it impossible to adjust the connection angle and position, hindering series operation. Improvements are needed. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide an injection mold for eyeglass frames. By setting sliding holes and circular rods in the mold body, a switching structure and a combined structure can be connected, facilitating the end-to-end connection for assembly and installation. It also facilitates switching of connection states, allowing for rigid connection or hinged installation, and is easy to adjust and use in combination.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An injection mold for eyeglass frames includes a mold body. Sliding holes are provided on both ends of the mold body. A circular rod is slidably connected inside the sliding holes. A hinge seat is hinged to one end of the circular rod. A connecting rod is provided at one end of the hinge seat. A switching structure is provided at one end of the connecting rod. A combination structure is provided at the other end of the connecting rod.

[0008] Furthermore, the switching structure includes a threaded hole and a threaded head, the threaded head being threadedly installed inside the threaded hole.

[0009] Furthermore, the threaded hole is located at one end of the sliding hole, and the threaded hole is sleeved on the surface of the hinge seat.

[0010] Furthermore, one end of the threaded head is connected to one side of the hinge seat, and the other end of the threaded head is connected to the connecting rod. The threaded head is connected through the threaded hole, which can be threaded and locked, facilitating rigid connection and easy adjustment.

[0011] Furthermore, the combined structure includes an adjusting head and a combined ring, the combined ring being connected to one end of the adjusting head.

[0012] Furthermore, the adjusting head is a circular rod structure, and the combined ring is a flat circular ring structure.

[0013] Furthermore, one end of the adjusting head is provided with a rotating block, which is rotatably connected to one end of the connecting rod. The adjusting head and connecting rings can be combined and connected to each other, facilitating locking and securing, and ensuring stability.

[0014] Compared with the prior art, the advantages of this invention are:

[0015] (1) This solution uses sliding holes and circular rods in the mold body to connect the switching structure and the combined structure, which makes it convenient to connect the ends for combined installation. It also facilitates switching the connection state, allowing for rigid connection or hinged installation, which is easy to adjust and convenient for combined use.

[0016] (2) The threaded head can be connected through the threaded hole, which can be threaded and locked, which is conducive to rigid connection and convenient for adjustment and use.

[0017] (3) The combination rings can be connected by adjusting the head, which is conducive to locking and fixing, and is convenient and stable. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1 and Figure 2 An injection mold for an eyeglass frame includes a mold body 1. Sliding holes 11 are provided on both ends of the mold body 1. A circular rod 12 is slidably connected inside the sliding holes 11. A hinge seat 13 is hinged to one end of the circular rod 12. A connecting rod 14 is provided at one end of the hinge seat 13. A switching structure 15 is provided at one end of the connecting rod 14. A combination structure 16 is provided at the other end of the connecting rod 14.

[0025] The switching structure 15 includes a threaded hole 17 and a threaded head 18. The threaded head 18 is threadedly installed inside the threaded hole 17, which is located at one end of the sliding hole 11. The threaded hole 17 is fitted onto the surface of the hinge seat 13. One end of the threaded head 18 is connected to one side of the hinge seat 13, and the other end is connected to the connecting rod 14. The threaded head can be threadedly locked through the threaded hole, which is conducive to rigid connection and easy to adjust. After the threaded head 18 is connected to the inside of the threaded hole 17, the connecting rod 14 can be fixedly installed, thus achieving a rigid connection. After the threaded head 18 is unscrewed, the hinge seat 13 can be pulled out, allowing the connecting rod 14 to swing left and right through the hinge seat 13, enabling a hinged connection. This avoids mutual interference after the mold bodies 1 are connected in series, facilitates alignment installation, and has high adaptability.

[0026] Example 2: Please refer to Figure 1 and Figure 3 An injection mold for an eyeglass frame includes a mold body 1. Sliding holes 11 are provided on both ends of the mold body 1. A circular rod 12 is slidably connected inside the sliding holes 11. A hinge seat 13 is hinged to one end of the circular rod 12. A connecting rod 14 is provided at one end of the hinge seat 13. A switching structure 15 is provided at one end of the connecting rod 14. A combination structure 16 is provided at the other end of the connecting rod 14.

[0027] The combined structure 16 includes an adjusting head 2 and a combined ring 21. The combined ring 21 is connected to one end of the adjusting head 2. The adjusting head 2 is a circular rod structure, and the combined ring 21 is a flat circular ring structure. One end of the adjusting head 2 is provided with a rotating block 22, which is rotatably connected to one end of the connecting rod 14. By connecting the adjusting head and the combined ring, they can be combined and connected to each other, which is convenient for locking and fixing, and convenient for stability. Two combined rings 21 are installed side by side, and then combined and positioned with bolts and nuts, which is convenient and efficient.
