Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, specifically a split injection molding tool. Background Technology

[0002] In the realm of professional DIY bait making, experienced enthusiasts typically create their own 3D-printed molds, aluminum molds, or plaster molds for personalized creations. The process primarily involves heating materials such as thermoplastic PVC resin to a molten state, then injecting the molten resin into the mold using a high-temperature injector to shape various unique baits or other models. However, this process presents significant operational challenges: the heating stage requires real-time temperature monitoring, and crucial steps such as defoaming and stirring often rely on manual labor. This not only poses a risk of burns but also easily leads to hand contamination and clothing stains, impacting both the experience and efficiency of the process.

[0003] To address the aforementioned pain points, existing technologies typically integrate a heating module and stirring assembly directly into a high-temperature resistant syringe. The heating module melts the raw materials, while the stirring structure efficiently defoams the foam. This optimized design significantly lowers the barrier to entry, allowing enthusiasts to easily create various personalized soft bait models at home without the need for specialized equipment.

[0004] However, current syringes generally adopt an integrated design, requiring the drive module that rotates the stirring assembly, as well as the power supply for both the drive and heating modules, to be integrated within the syringe. While this highly integrated structure improves functional integration, it significantly increases the overall weight of the syringe. In actual operation, users are prone to fatigue when holding it for extended periods, severely impacting the flexibility and convenience of injection operations. Therefore, we propose a split-type injection molding tool to effectively address these drawbacks. Utility Model Content

[0036] 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.

[0037] Please see Figures 1 to 10 A split injection molding tool includes a housing 1 and a base 2 detachably connected to the bottom of the housing 1; the housing 1 and the base 2 can be separated vertically and independently.

[0038] To address the problem that the integrated design of syringes in existing technologies severely affects the flexibility and convenience of injection operations, the following design is proposed:

[0039] A syringe 3 is fixedly installed inside the outer casing 1 for drawing or inserting raw materials, and for injecting molten raw materials into a mold. A heating and insulation component 4 is installed on the outer wall of the syringe 3, which efficiently heats the raw materials while effectively blocking heat, ensuring user comfort. A stirring component 5 is rotatably connected to the bottom of the syringe 3 for stirring and defoaming the raw materials inside. A button battery 6 and a first mainboard 7 are fixedly installed inside the outer casing 1. When the outer casing 1 is separated from the base 2, the button battery 6 can directly power the components inside the outer casing 1 that require power. A temperature measuring and display component 8, connected to the outer wall of the syringe 3, is fixedly installed on the outer wall of the outer casing 1 to monitor and display the internal temperature of the syringe 3 in real time. The heating and insulation component 4, the button battery 6, and the temperature measuring and display component 8 are electrically connected to the first mainboard 7. When the outer casing 1 is separated from the base 2, the heating and insulation component 4 and the temperature measuring and display component 8 can be controlled through the first mainboard 7.

[0040] A second mainboard 9, a battery 10, and a drive assembly 11 are fixedly installed inside the base 2. The drive assembly 11 drives the stirring assembly 5 to rotate. The battery 10 and the drive assembly 11 are electrically connected to the second mainboard 9. In this embodiment, a temperature adjustment button, a stirring start / stop button, and a power switch are fixedly installed on the outer wall of the base 2. Each button is electrically connected to the second mainboard 9, facilitating parameter adjustment and function control by the user. A charging interface electrically connected to the second mainboard 9 is also provided on the base 2 for charging the battery 10.

[0041] Additionally, it should be noted that the top of the base 2 is fixed with several elastic power supply contacts 17, each of which is electrically connected to the second main board 9; the bottom of the outer casing 1 is fixed with energized contacts 18 corresponding to each of the elastic power supply contacts 17, each of which is electrically connected to the first main board 7. When the outer casing 1 is placed on the base 2, each elastic power supply contact 17 contacts the corresponding energized contact 18, thereby supplying power to the electrical components in the outer casing 1 through the battery 10.

[0042] Using the above structure, the injection molding material is first loaded into the syringe 3, and then the outer shell 1 is placed on the base 2. At this time, the battery 10 in the base 2 supplies power to the heating and insulation component 4 and the temperature display component 8 on the outer shell 1. The heating and insulation component 4 is activated to heat the material, and the drive component 11 is turned on to drive the stirring component 5 to rotate, realizing the stirring and defoaming of the material. At the same time, the temperature change is monitored in real time by the temperature display component 8. After the material is completely melted, the outer shell 1 is separated from the base 2. The user holds the outer shell 1 and can inject the material into the mold through the syringe 3 to complete the injection molding operation. Compared with the traditional integrated syringe, the weight of the hand is reduced, the operator fatigue is reduced, and it is especially suitable for long-term or precision injection operations, greatly improving the flexibility and convenience of operation.

[0043] The following is a description of syringe 3:

[0044] The syringe 3 includes a glass tube 301 fixed inside the outer casing 1 and open at the top. A fixing sleeve 12 is fixed at the bottom of the outer casing 1, and an inlet / outlet 21 communicating with the inner cavity of the glass tube 301 is passed through the fixing sleeve 12. A rotating plug 19 is rotatably connected inside the fixing sleeve 12, and an eccentric needle 302 that mates with the inlet / outlet 21 is fixed on the rotating plug 19. Under normal conditions, the rotating plug 19 is rotated to offset the eccentric needle 302 from the inlet / outlet 21, preventing the material in the glass tube 301 from flowing out. When it is necessary to inject material, the rotating plug 19 is rotated to align the eccentric needle 302 with the inlet / outlet 21, so that the material in the glass tube 301 can be injected into the mold.

[0045] It should be added that several arc-shaped limiting holes 20 are spaced circumferentially through the rotating plug 19, and limiting rods corresponding to each arc-shaped limiting hole 20 are fixed on the fixed sleeve 12. When the rotating plug 19 is rotated, the cooperation of the arc-shaped limiting holes 20 and the limiting rods can prevent the rotating plug 19 from rotating excessively, ensuring that after rotating to the limiting position, the eccentric needle 302 can be completely aligned with or completely offset from the inlet / outlet 21.

[0046] In addition, the top of the base 2 is provided with a placement groove 13 that corresponds to the rotating plug 19 and the fixing sleeve 12. After the outer shell 1 is placed on top of the base 2, the rotating plug 19 and the fixing sleeve 12 can be inserted into the placement groove 13. At the same time, a positioning hole 29 is provided on the top of the base 2, and a positioning rod 30 that matches the positioning hole 29 is fixed on the bottom of the outer shell 1, which can position the outer shell 1. When it is necessary to separate the outer shell 1 from the base 2, the outer shell 1 can be lifted upwards directly. The structure is simple and the operation is convenient.

[0047] In this embodiment, the heating and insulation component 4 is disposed on the outer wall of the glass tube 301. The stirring component 5 is rotatably connected to the inner bottom of the glass tube 301, and the temperature measuring and display component 8 is connected to the outer wall of the glass tube 301. The upper end of the glass tube 301 is open to facilitate the addition of granular, powdered, or other solid raw materials into the glass tube 301. The upper end of the outer shell 1 is also open, and a top cover 14 for sealing the upper opening of the glass tube 301 is detachably connected to the upper end of the outer shell 1. The top cover 14 is connected to the outer shell 1 by a rotating snap fastener, and a waterproof ring is provided on the contact surface to prevent liquid from flowing out of the top cover 14. A fluororubber waterproof component is provided at the junction of the upper end of the glass tube 301 and the outer shell 1 to prevent liquid from flowing from the glass tube 1 into the outer shell 1. When it is necessary to add solid raw materials, the top cover 14 is opened to pour the solid raw materials into the glass tube 301. When adding liquid raw materials, they can be directly extracted.

[0048] The syringe 3 also includes a piston 303 slidably connected within the glass tube 301. A push rod 304 is fixed to the upper end of the piston 303, which moves upward through the upper cover 14 and has a handle 305 fixed to its upper end. When liquid material needs to be drawn, pulling the handle 305 upward causes the piston 303 to slide upward within the glass tube 301, allowing the liquid material to be drawn through the eccentric needle 302. When molten material needs to be injected, pushing the handle 305 allows the material to be injected into the mold through the eccentric needle 302.

[0049] It should be added that the push rod 304 is hollow, and several vent ports 22 are spaced apart along the circumference of the push rod 304, which communicate with the inner cavity of the push rod 304. The bottom of the piston 303 has a receiving groove 23 that communicates with the push rod 304. A connecting rod 24 is movably inserted into the push rod 304, and a sealing block 25 located in the receiving groove 23 is fixed at the lower end of the connecting rod 24. A sealing ring 26 is provided at the junction of the sealing block 25 and the piston 303. Under normal conditions, the sealing block 25 and the piston 303 are stacked together to prevent liquid in the glass tube 301 from entering the receiving groove 23. In addition, a clearance groove adapted to the stirring assembly 5 is reserved at the bottom of the sealing block 25, so that when the sealing block 25 is pushed to the bottom of the glass tube 301 along with the piston 303, it will not come into contact with the stirring assembly 5.

[0050] A pressing rotary seat 27 is fixed to the upper end of the connecting rod 24. The pressing rotary seat 27 is movably embedded in the top of the handle 305. A return spring 28 is provided on the top of the push rod 304 to apply an upward elastic force to the pressing rotary seat 27. Specifically, a cylinder 31 adapted to the pressing rotary seat 27 is fixed to the inner top of the handle 305. Two positioning protrusions 32 are symmetrically arranged at the lower end of the pressing rotary seat 27. A positioning groove 33 is provided at the bottom of the cylinder 31 to position each positioning protrusion 32.

[0051] In the initial state, each positioning protrusion 32 is engaged in the corresponding positioning groove 33. At this time, under the action of the return spring 28, the sealing block 25 and the piston 303 cooperate to press the sealing ring 26, thereby preventing the liquid in the glass tube 301 from entering the push rod 304. When it is necessary to heat the raw material in the glass tube 301, the pressing rotary seat 27 is first moved downward and rotated. Under the constraint of the positioning protrusion 32, the pressing rotary seat 27 is kept in the contracted state. At this time, there is an annular gap between the sealing block 25 and the piston 303. The gas in the glass tube 301 can enter the push rod 304 through the annular gap and be discharged through the exhaust port 22, preventing the gas volume from remaining in the glass tube 301 and causing the pressure in the glass tube 301 to increase.

[0052] It is worth mentioning that a transparent window 15, adapted to the glass tube 301, is embedded in the side wall of the outer casing 1, allowing the user to easily observe the melting state of the raw material inside the glass tube 301. An indicator light 16 is fixedly installed at the bottom of the transparent window 15, and the indicator light 16 is electrically connected to the first main board 7. When the temperature reaches the injection temperature, the green light illuminates, allowing the user to remove the outer casing 1 from the base 2. When the temperature drops to a point where injection is not possible, the indicator light 16 illuminates red, prompting the user to return the casing to the base 2 for heating.

[0053] The following is a description of the heating and insulation component 4:

[0054] The heating and insulation assembly 4 includes heat insulation cotton 401 covering the outer wall of the syringe 3 for heat insulation. A heating wire (not shown in the figure) is provided on the inner side of the heat insulation cotton 401 and wound around the outer wall of the syringe 3. The heating wire is electrically connected to the first main board 7 to uniformly heat the raw material in the syringe 3.

[0055] The following is an introduction to the temperature measurement and display component 8:

[0056] The temperature measurement and display assembly 8 includes a temperature display screen 801 fixed to the outer wall of the housing 1 for displaying the temperature. A patch thermocouple is connected to the outer wall of the syringe 3. The patch thermocouple and the temperature display screen 801 are electrically connected to the first main board 7 for measuring the temperature of the glass tube 301 and displaying it in real time.

[0057] The following is a description of the stirring component 5:

[0058] The stirring assembly 5 includes a stirring shaft 501 rotatably connected to the bottom of the syringe 3. A stirring paddle located inside the syringe 3 is fixed at the upper end of the stirring shaft 501, and an internal hexagonal groove 502 is provided at the lower end of the stirring shaft 501. When the stirring shaft 501 rotates, it can drive the stirring paddle to rotate, thereby stirring and defoaming the raw materials in the glass tube 301.

[0059] In this embodiment, the drive assembly 11 includes a motor 111 fixedly installed in the base 2. The motor 111 is electrically connected to the second main board 9. An external hexagonal protrusion 112 that mates with the internal hexagonal groove 502 is connected to the output end of the motor 111. When the outer shell 1 is positioned on the base 2, the external hexagonal protrusion 112 can be smoothly inserted into the internal hexagonal groove 502. Therefore, when the motor 111 is working, the hexagonal structure can drive the stirring shaft 501 to rotate, thereby stirring and defoaming the raw materials in the glass tube 301 through the stirring paddle.
