Description

Technical Field

[0001] This utility model relates to the field of jewelry manufacturing technology, specifically a mold for jewelry manufacturing. Background Technology

[0002] Jewelry manufacturing is a collective term for all processes used to shape various raw materials into finished products. Specifically, it includes handcrafting, machining, and surface treatment of precious metal jewelry. Some metal jewelry is manufactured using molds for stamping.

[0003] For example, Chinese Patent Publication No. CN206543863U, entitled "Mold for Jewelry Manufacturing," describes a mold for jewelry manufacturing. This mold includes a base, a top cover that mates with the base, and a mold core. The top cover and base together form a receiving space, within which the mold core is housed. The mold core is made of tin or a tin alloy and comprises multiple detachable mold core parts. These multiple mold core parts cooperate to form a molding pattern. The connection line between two adjacent mold core parts is offset from grooves, patterns, or pre-printed areas in the molding pattern. Compared to ordinary rubber molds, the mold provided by this utility model, due to its tin alloy mold core, has advantages such as higher precision and easier dimensional control.

[0004] However, in actual use, it has the problem of not being convenient to fix and limit the upper and lower molds. When using it, multiple detachable mold parts are used in conjunction with the top cover to shape the jewelry. The multiple detachable mold parts need to be placed into the receiving space one by one during installation, which is complicated and not convenient to fix or unfix multiple sets of mold parts at the same time. Therefore, a mold for jewelry manufacturing is proposed to solve the above-mentioned problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a mold for jewelry manufacturing, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mold for jewelry manufacturing, including a base plate, a top plate fixedly connected to the base plate by a support rod, a pressure assembly provided below the top plate, the pressure assembly including a pressure plate, a mold assembly including two limiting frames, the two limiting frames being fixedly connected to the bottom plate and the top plate respectively, an upper mold and a lower mold being movably fitted onto the inner surfaces of the two limiting frames respectively, and first fixing components being provided on the left and right sides of the upper mold and the lower mold, the first fixing components including fixing sleeves, the number of fixing sleeves being... There are four fixed sleeves, which are respectively fixedly connected to the left and right sides of the upper and lower molds. Fixed rods are slidably connected to the inner surfaces of the four fixed sleeves. A sliding component is provided behind the fixed rod. When it is necessary to install the mold, the upper and lower molds are placed in the limiting frame. At this time, the two fixed rods on the upper and lower parts of the back plate are aligned with the fixed sleeves on the lower mold from the rear. The two fixed rods on the upper part are adjusted to align with the fixed sleeves on the upper mold by sliding the card seat up and down on the limiting strip. Then, by moving the back plate to the front, the fixed rods are inserted into the fixed sleeves, so that the upper and lower molds cannot fall off the limiting frame, thus achieving the purpose of installing the mold.

[0007] Preferably, the pressurizing assembly further includes a push rod that movably passes through the top of the top plate and is fixedly connected to the top of the pressure plate. A limit rod is fixedly connected to the top of the pressure plate and movably passes through the top of the top plate. In use, the raw material is first placed on the lower mold, and then the push rod is pushed by an external stamping device to press the pressure plate downward, thereby causing the upper mold and the lower mold to engage, thus enabling the processing of ornaments.

[0008] Preferably, there are four fixing rods, which are arranged in pairs, one above the other, and are respectively arranged on the left and right sides of the upper and lower molds.

[0009] Preferably, the sliding assembly includes a retainer that engages with the rear of the pressure plate. A connecting block is fixedly connected below the retainer, and the connecting block is fixedly connected to the rear ends of the two upper fixing rods. When the two upper fixing rods are aligned and inserted into the fixing sleeve on the upper mold, the retainer will also hold the pressure plate. At this time, the push rod is pushed by the external stamping equipment, causing the pressure plate to press down. At the same time, the pressure plate will drive the retainer to slide on the limit strip. The retainer will drive the connecting block so that the two upper fixing rods always follow the rise and fall of the pressure plate to fix the fixing sleeve on the upper mold, thereby ensuring the normal use of the mold.

[0010] Preferably, the sliding assembly further includes a back plate, which is fixedly connected to the rear ends of the two fixed rods located below. A limit strip is fixedly connected to the front of the back plate, and the limit strip is slidably connected to the rear of the card seat. A second fixing assembly is provided on the front of the back plate. At this time, by pulling the back plate backward, the fixed rod is pulled out from the inner surface of the fixing sleeve. After the fixed rod is pulled out from the fixing sleeve, the upper mold and the lower mold can be removed from the limit frame, thereby achieving the function of disassembling the upper mold and the lower mold.

[0011] Preferably, the second fixing component includes a fixing column, which is fixedly connected between the bottom plate and the top plate. A bolt is threaded through the front of the fixing column, and the bolt is threaded to the front of the back plate. When it is necessary to disassemble the mold, the bolt on the fixing column is loosened to release the fixing to the back plate.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. A mold for jewelry manufacturing, which can drive the first fixing component to simultaneously release the fixing of the upper mold and the lower mold in the mold assembly by moving the sliding component backward, thus facilitating the assembly and disassembly of the mold.

[0014] 2. This mold for jewelry manufacturing has a sliding component that slides along with the upper mold when the upper mold is pressed down by the pressure component, so as to ensure that the upper mold is fixed at any time, which makes it easy to use. Attached Figure Description
