Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of spectacle frame production equipment, concretely to a spectacle frame manufacturing die. BACKGROUND
[0002] Producing spectacle frames for supporting lenses involves multiple stages, such as the design stage, material preparation, forming processing, surface treatment, etc. Among them, forming processing includes injection molding, metal casting, sheet metal processing, and other methods.
[0003] Injection molding is mainly used for the manufacture of plastic frames. The pretreated plastic material is added to the hopper of the injection molding machine. The injection molding machine melts the plastic particles by heating, and then under the push of the screw, the melted plastic is injected into the preheated mold cavity at high pressure and high speed. After the pressure holding and cooling stages, the plastic is solidified and formed in the cavity. After opening the mold, the initial product is taken out, and subsequent processing such as gate removal and edge trimming is performed.
[0004] Currently, there are many molds for injection molding of spectacle frames. For example, a Chinese patent with publication number CN214353617U discloses a spectacle frame demolding mechanism and a spectacle frame mold. It includes a first movable piece, a second movable piece, and a pulling block. The side of the first movable piece facing the second movable piece is a first matching curved surface. The second movable piece has a corresponding second matching curved surface. A portion of the first matching curved surface abuts a corresponding portion of the second matching curved surface. The remaining portions of the first and second matching curved surfaces have a predetermined gap between them. A first hinge part is provided on the first movable piece, and a second hinge part is formed on the second movable piece at a corresponding position. The first and second hinge parts are used to connect the mold with a fastener hinge, respectively. The first and second movable pieces are connected to the pulling block through a hinge, respectively. The pulling block moves back and forth relative to the two movable pieces, driving them to rotate towards each other, so that the first and second matching curved surfaces overlap.
[0005] When using the spectacle frame mold to manufacture the frame, it needs to be equipped with a corresponding lens model to form a hole on the spectacle frame that can load the lens. The sidewall of the hole has a clamping groove that matches the lens to stabilize the installation of the lens on the frame.
[0006] Although the lens model can cooperate with the mold to form an injection cavity for the frame, it has some defects. For example, the lens model is in a buckle connection with the formed frame, which means that after the frame is formed, the lens model has resistance to demolding the frame, and even manual disassembly may damage the frame and affect the injection efficiency of the frame.
