[0003] In the process of jewelry production, it is necessary to use an injection mold to perform injection molding before it can be formed and the next step can be performed. When the existing plastic jewelry injection mold is used, multiple sets of bolts are usually used to connect the upper and lower molds. It is time-consuming and laborious to disassemble and assemble the upper and lower molds, and it is inconvenient to disassemble and assemble the injection mold.

[0004] A Chinese patent with publication number CN219338468U has been proposed in the prior art to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a plastic jewelry injection mold that is easy to disassemble and assemble, comprising: a base plate, a lower mold is fixedly installed on the top of the base plate, a fixed frame, a fixed frame is fixedly installed on the top of the base plate, a servo motor is fixedly installed on the top of the base plate, a bidirectional screw rod is fixedly connected to the output end of the servo motor, a movable plate is penetrated and connected to the outer wall of the bidirectional screw rod, and a connecting column is fixedly installed on the bottom of the upper mold. The utility model is provided with a fixed frame, a movable plate and a connecting column, the outer wall of the connecting column is fitted with the inner wall of the fixed frame, and a servo motor is started. The rotation of the servo motor drives the bidirectional screw to rotate, and the rotation of the bidirectional screw drives the two sets of movable plates to move in opposite directions.

However, it is inconvenient to discharge the ornaments after injection molding, thereby affecting the work efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic discharging jewelry injection mold to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A jewelry injection mold with automatic discharging comprises a base; a support frame is fixedly installed on the top of the base, an ejection plate is arranged inside the support frame, a hydraulic cylinder is fixedly installed on the top of the base, the hydraulic cylinder is fixedly connected to the bottom of the ejection plate, a controller is fixedly installed on the top of the base at one end of the hydraulic cylinder, a lower mold is fixedly connected to the top of the support frame, a rubber frame is attached to the inside of the lower mold, an upper mold is arranged on the top of the lower mold, hydraulic rods are fixedly installed on the top of the base on both sides of the support frame, the hydraulic rods are fixedly connected to both sides of the upper mold, a fixing plate is arranged on the top of the upper mold, a connecting plate is arranged at the bottom of the fixing plate, a clamping plate is fixedly installed at the bottom of the connecting plate, clamps and components are arranged on both sides of the upper mold, the clamps and components are used to clamp the connecting plate into the interior of the upper mold, and a recovery component is fixedly installed on the top of the fixing plate, the recovery component is used to restore the connecting plate to a position fitting with the bottom of the fixing plate.

[0008] By installing a hydraulic rod, the upper mold can be driven to move up and down. After the hydraulic rod drives the top of the upper mold to fit with the fixed plate, the card and components can be used to connect the connecting plate to the upper mold, and then the hydraulic rod is used to drive the upper mold to move downward, and at the same time, the card plate can be driven to move downward synchronously. In the process of the card plate being inserted between the finished product of the injection molding of the jewelry and the rubber frame, the rubber frame can be squeezed outward and deformed, so that the finished product of the injection molding of the jewelry and the rubber frame can be separated, so as to facilitate the subsequent demoulding and unloading of the finished product of the injection molding of the jewelry. When the hydraulic rod drives the upper mold to fit with the fixed plate again, the card and components are used again to separate the connecting plate from the upper mold, and the recovery component can be used to limit the connecting plate to prevent the connecting plate from moving downward with the upper mold again, thereby avoiding affecting the subsequent injection molding of the jewelry. By installing a hydraulic cylinder, the ejector plate can be driven to move upward, so that after the upper mold and the lower mold are separated, the finished product of the injection molding of the jewelry can be ejected upward, so as to realize automatic unloading of the finished product of the injection molding of the jewelry.

[0009] A further improvement of the technical solution of the utility model is that the card and components include a card block, which is slidably connected to the inside of the upper mold, electric push rods are fixedly installed at both ends of the upper mold, the electric push rods are fixedly connected to the card block, and a switch is fixedly installed at the bottom inside the fixed plate.

[0010] The above-mentioned technical scheme is adopted. In this scheme, an electric push rod is installed to drive the card block to move, so that after the upper mold moves to the periphery of the connecting plate, the card block can be driven to continue to move toward the inner end, so that the card block is stuck in the interior of the connecting plate, thereby realizing the connection between the connecting plate and the upper mold. The electric push rod can be controlled by installing a switch. When the upper mold moves upward and the switch is pressed once, the electric push rod can be automatically turned on and extended to the inner end. When the upper mold presses the switch upward again, the electric push rod can be automatically turned off and retracted to the outer end, thereby realizing automatic connection and separation between the connecting plate and the upper mold.

[0011] A further improvement of the technical solution of the utility model is that the periphery of the card plate is an inclined surface inclined toward the bottom, and the bottom of the card plate and the interior of the rubber frame are perpendicular to each other.

[0012] The above technical solution is adopted. In this solution, by setting the periphery of the card board as an inclined surface inclined toward the bottom, the card board can be easily inserted between the injection-molded jewelry product and the rubber frame, so as to facilitate the subsequent separation of the injection-molded jewelry product and the rubber frame.

[0013] A further improvement of the technical solution of the utility model is that a card slot matching the shapes of the connecting plate and the card plate is opened inside the upper mold, and the card plate can pass through the upper mold.

[0014] The above technical solution is adopted. In this solution, by opening a card slot inside the upper mold, the card plate can be easily moved up and down inside the upper mold, so as to facilitate the subsequent connection processing between the upper mold and the connecting plate.

[0015] A further improvement of the technical solution of the utility model is that the recovery component includes a fixing frame, which is fixedly connected to the top of the fixing plate, and a spring is fixedly installed on the bottom of the fixing frame, which runs through the interior of the fixing plate and is fixedly connected to the top of the connecting plate.

[0016] The above technical solution is adopted. In this solution, the fixing frame and the connecting plate can be connected by installing a spring. After the clamping block is separated from the inside of the connecting plate, the connecting plate can be limited by the tension of the spring to prevent the connecting plate from moving downward and affecting the injection molding of the accessories.

[0017] A further improvement of the technical solution of the utility model is that a slide bar is fixedly installed on the top of the connecting plate, and the slide bar runs through the inside of the spring and the fixing frame.

[0018] The above technical solution is adopted. In this solution, the sliding trajectory of the connecting plate can be guided and limited by installing a slide rod, thereby ensuring that the connecting plate can maintain linear movement and ensuring that the card plate can be completely inserted between the finished injection-molded jewelry product and the rubber frame.

[0019] A further improvement of the technical solution of the utility model is that: fixing rods are fixedly installed on the tops of the support frames at both ends of the lower mold, and the fixing rods are fixedly connected to the fixing plates.

[0020] By adopting the above technical solution, in this solution, the fixing plate and the support frame can be connected by installing the fixing rod, thereby improving the stability of the fixing plate installation.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides an automatic unloading jewelry injection mold. Through the mutual cooperation between the card and the components, the connecting plate and the upper mold can be connected or separated. After the card block is inserted into the interior of the connecting plate, the hydraulic rod is used to drive the upper mold to move downward. At the same time, the card plate can be used to separate the finished jewelry injection molded product and the rubber frame, so as to facilitate the subsequent unloading of the finished jewelry injection molded product. The finished jewelry injection molded product can be ejected upward by using a hydraulic cylinder and an ejector plate, thereby realizing automatic unloading of the finished jewelry injection molded product.

[0023] 2. The utility model provides an automatic discharging jewelry injection mold. After the clamping block is separated from the connecting plate, the connecting plate can be limited by a spring, thereby avoiding affecting the injection molding of the jewelry.

[0024] 3. The utility model provides an automatic discharging jewelry injection mold, which uses a sliding rod to ensure that the connecting plate can maintain linear movement, and further ensures that the card plate can be completely inserted between the jewelry injection molded product and the rubber frame, so as to facilitate the subsequent separation of the jewelry injection molded product and the rubber frame.

DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the embodiments:

[0033] Example 1

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides an automatic discharging jewelry injection mold, including a base 1; a support frame 2 is fixedly installed on the top of the base 1, an ejection plate 901 is arranged inside the support frame 2, a hydraulic cylinder 9 is fixedly installed on the top of the base 1, the hydraulic cylinder 9 is fixedly connected to the bottom of the ejection plate 901, a controller 4 is fixedly installed on the top of the base 1 at one end of the hydraulic cylinder 9, a lower mold 5 is fixedly connected to the top of the support frame 2, a rubber frame 501 is attached to the inside of the lower mold 5, an upper mold 6 is arranged on the top of the lower mold 5, and the two ends of the support frame 2 are fixedly connected to the bottom of the ejection plate 901. A hydraulic rod 10 is fixedly installed on the top of the base 1 on the side, and the hydraulic rod 10 is fixedly connected to the two sides of the upper mold 6. A fixing plate 3 is provided on the top of the upper mold 6, and a connecting plate 11 is provided at the bottom of the fixing plate 3. A clamping plate 12 is fixedly installed on the bottom of the connecting plate 11. Cards and components 7 are provided on both sides of the upper mold 6, and the card and component 7 are used to clamp the connecting plate 11 into the interior of the upper mold 6. A recovery component 8 is fixedly installed on the top of the fixing plate 3, and the recovery component 8 is used to restore the connecting plate 11 to a position where it fits with the bottom of the fixing plate 3.

[0035] In this embodiment, the upper mold 6 can be driven to move up and down by installing a hydraulic rod 10. After the hydraulic rod 10 drives the top of the upper mold 6 to fit with the fixed plate 3, the connecting plate 11 can be connected to the upper mold 6 by using the card and component 7, and then the upper mold 6 is driven to move downward by the hydraulic rod 10, and the card plate 12 can be driven to move downward synchronously at the same time. When the card plate 12 is inserted between the finished jewelry injection molded product and the rubber frame 501, the rubber frame 501 can be squeezed outward and deformed, so that the finished jewelry injection molded product and the rubber frame 501 can be separated. It is convenient for the subsequent demolding and unloading of the finished injection-molded jewelry. When the hydraulic rod 10 drives the upper mold 6 to fit with the fixed plate 3, the card and component 7 are used again to separate the connecting plate 11 from the upper mold 6. The recovery component 8 can be used to limit the connecting plate 11 to prevent the connecting plate 11 from moving downward with the upper mold 6, thereby avoiding affecting the subsequent injection molding of the jewelry. By installing the hydraulic cylinder 9, the ejection plate 901 can be driven to move upward, so that after the upper mold 6 and the lower mold 5 are separated, the finished injection-molded jewelry can be ejected upward, thereby realizing automatic unloading of the finished injection-molded jewelry.

[0036] Example 2

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the card and component 7 include a card block 702, which is slidably connected to the inside of the upper mold 6, and electric push rods 703 are fixedly installed at both ends of the upper mold 6, and the electric push rods 703 are fixedly connected to the card block 702, and a switch 701 is fixedly installed at the bottom inside the fixed plate 3, the outer periphery of the card plate 12 is an inclined surface inclined toward the bottom, and the bottom of the card plate 12 is perpendicular to the inside of the rubber frame 501, and a card slot matching the shape of the connecting plate 11 and the card plate 12 is opened inside the upper mold 6, and the card plate 12 can pass through the upper mold 6.

[0038] In this embodiment, the electric push rod 703 can be installed to drive the clamping block 702 to move, so that after the upper mold 6 moves to the periphery of the connecting plate 11, the clamping block 702 can be driven to continue to move inward, so that the clamping block 702 is inserted into the interior of the connecting plate 11, thereby realizing the connection between the connecting plate 11 and the upper mold 6. The electric push rod 703 can be controlled by installing the switch 701. When the upper mold 6 moves upward and the switch 701 is pressed once, the electric push rod 703 can be automatically turned on, so that the electric push rod 703 extends to the inner end. When the upper mold 6 is pressed upward again, After the switch 701 is turned on, the electric push rod 703 can be automatically closed, so that the electric push rod 703 shrinks to the outer end, thereby automatically connecting and separating the connecting plate 11 and the upper mold 6. By setting the outer periphery of the card plate 12 as an inclined surface inclined toward the bottom, the card plate 12 can be easily inserted between the finished jewelry injection product and the rubber frame 501, so as to facilitate the subsequent separation of the finished jewelry injection product and the rubber frame 501. By providing a card slot inside the upper mold 6, the card plate 12 can be easily moved up and down inside the upper mold 6, so as to facilitate the subsequent connection processing between the upper mold 6 and the connecting plate 11.

[0039] Example 3

[0040] like Figure 1 and Figure 3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the recovery component 8 includes a fixing frame 802, which is fixedly connected to the top of the fixing plate 3, and a spring 801 is fixedly installed at the bottom of the fixing frame 802, and the spring 801 passes through the interior of the fixing plate 3 and is fixedly connected to the top of the connecting plate 11, and a sliding rod 803 is fixedly installed on the top of the connecting plate 11, and the sliding rod 803 passes through the interior of the spring 801 and the fixing frame 802.

[0041] In this embodiment, the fixing frame 802 and the connecting plate 11 can be connected by installing the spring 801. After the block 702 is separated from the inside of the connecting plate 11, the tension of the spring 801 can be used to limit the connecting plate 11 to prevent the connecting plate 11 from moving downward and affecting the injection molding of the accessories. The sliding trajectory of the connecting plate 11 can be guided and limited by installing the slide rod 803, thereby ensuring that the connecting plate 11 can maintain linear movement and ensuring that the card plate 12 can be completely inserted between the finished injection-molded accessory and the rubber frame 501.

[0045] The following is a detailed description of the working principle of the automatic discharging jewelry injection mold.

[0046] like Figure 1-Figure 5 As shown, when the upper mold 6 and the lower mold 5 are fitted together, the user can pour the jewelry raw material into the space between the upper mold 6 and the lower mold 5 through the injection port at the top of the upper mold 6 to perform injection molding on the jewelry. After the injection molding is completed, the user can use the hydraulic rod 10 to drive the upper mold 6 to move upward, and the upper mold 6 can squeeze the switch 701 once, and the switch 701 can control the electric push rod 703 to extend inward, and the card block 702 is inserted into the interior of the connecting plate 11. Then, the hydraulic rod 10 is used to drive the upper mold 6 to move downward, and the card plate 12 is used to squeeze the rubber frame 501 outward and deform it, and the card plate 1 2 is inserted between the finished injection-molded jewelry and the rubber frame 501, thereby separating the finished injection-molded jewelry and the rubber frame 501, so as to facilitate the subsequent unloading of the finished injection-molded jewelry. The hydraulic rod 10 is then used to drive the upper mold 6 to move upward, and the switch 701 is pressed again to separate the connecting plate 11 from the clamping block 702. The spring 801 can prevent the connecting plate 11 from moving downward with the upper mold 6. The user then uses the hydraulic cylinder 9 to drive the ejection plate 901 to move upward, and at the same time, the finished injection-molded jewelry is ejected upward, thereby realizing automatic unloading of the finished injection-molded jewelry.

[0047] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
