Description

Technical Field

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

[0002] A toothbrush is a cleaning product with a handle. Toothpaste is applied to the brush, and then the teeth are repeatedly brushed to maintain oral hygiene. The manufacture of toothbrush handles requires the use of injection molding equipment; injection molding is an industrial product manufacturing method. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting.

[0003] An injection molding machine (or injection molding machine for short) is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through an injection molding machine and a mold.

[0004] In the prior art, there is an injection mold for a toothbrush handle with authorization announcement number CN210453563U. The injection mold for the toothbrush handle includes a mounting plate, a mold mechanism, a support mechanism, an injection mechanism, a heating mechanism, a limiting rod, a limiting groove, and a locking universal wheel. The mold mechanism is fixedly connected to the mounting plate. The mold mechanism includes a first mold, a second mold, a first forming groove, a second forming groove, a through groove, a fixing plate, a pad, a cylinder, and a piston rod. The first mold and the second mold are symmetrically arranged, and the first mold is fixedly connected to the mounting plate. The second mold is slidably connected to the mounting plate. Multiple sets of the first forming groove and multiple sets of the second forming groove are respectively opened on the opposite side wall of the first mold and the second mold.

[0005] While the above solution offers many advantages, it also has the following drawbacks: the device uses a heating plate to heat the injection material to prevent it from cooling down before filling the first and second molding tanks. However, the heated material cannot cool down quickly, resulting in a long waiting time after injection molding for the molded product to cool and solidify, thus reducing the working efficiency of the toothbrush handle injection molding device. Utility Model Content

[0025] Example: Figure 1 - Figure 6 As shown, this utility model provides a technical solution for a toothbrush handle injection molding device, including a device body 1. A first mold 2 and a second mold 3 are provided on the upper part of the device body 1. A mold cavity 4 is provided at the front end of the first mold 2, and a through-type hot and cold cavity 5 is opened on the upper part of the first mold 2. A heating plate 6 and a cooling plate 7 are slidably arranged and fixedly connected to each other in the hot and cold cavity 5. A cooling component is provided in the cooling plate 7, and a heating component is provided in the heating plate 6. A sliding mechanism is provided on the first mold 2 to drive the heating plate 6 and the cooling plate 7 to slide in the hot and cold cavity 5. A cylinder is provided on the device body 1, and the telescopic end of the cylinder is fixedly connected to one side of the second mold 3. The second mold 3 slides on the upper part of the device body 1.

[0026] Specifically, the first mold 2 has an injection pipe that runs through the mold cavity 4 at the front end, and an injection conduit that runs through the injection pipe is provided on one side of the first mold 2. The second mold 3 is driven by a cylinder to approach and merge with the first mold 2, and then the injection molding machine injects material into the injection conduit. The material flows into the mold cavity 4 through the injection pipe to form the mold.

[0027] like Figure 4 - Figure 6 As shown, a heating groove 9 is provided at the front end of the heating plate 6, and the heating component includes a heating tube 10 coiled on the inner wall of the heating groove 9. A power supply mechanism 11 is installed in the groove at the rear end of the heating plate 6, and the power supply mechanism 11 is electrically connected to the heating tube 10.

[0028] like Figure 3 , Figure 5 and Figure 6 As shown, a cooling tank 12 is provided at the front end of the cooling plate 7. The cooling component includes a cooling pipe 13 coiled on the inner wall of the cooling tank 12. A cooler 14 and a water tank 15 are installed on the main body 1 of the device. A water pump is installed in the water tank 15. The water pump outlet is connected to the water inlet of the cooler 14 through a conduit. The cooler 14 outlet is connected to one end of the cooling pipe 13 through a conduit. The other end of the cooling pipe 13 is fixedly connected to the side wall of the water tank 15 through a conduit.

[0029] Specifically, the device body 1 has two notches at the bottom, through which the conduit passes and connects to the cooler 14 and the cooling plate 7. The conduit is a flexible hose, and the cooling pipe 13 is a metal pipe.

[0030] like Figure 2 and Figure 6 As shown, both the bottom and the bottom of the hot and cold cavity 5 are formed with heat preservation cavity 16. The sliding mechanism includes a threaded rod 17 rotatably connected between the two heat preservation cavities 16. A slider is slidably sleeved on the outside of the threaded rod 17. The slider is fixed between the heating plate 6 and the cooling plate 7.

[0031] like Figure 5 and Figure 6 As shown, a heat-conducting plate 18 is provided at the opening of the heating tank 9. The heat-conducting plate 18 is in contact with the inner wall of the hot and cold cavity 5, but the heat-conducting plate 18 is not in contact with the heating tube 10.

[0032] Specifically, both the heat-conducting plate 18 and the heat exchange plate 19 are made of metal that absorbs and conducts heat.

[0033] like Figure 5 and Figure 6 As shown, a heat exchange plate 19 is provided at the opening of the cooling tank 12. One side of the heat exchange plate 19 is in contact with the inner wall of the hot and cold chamber 5, and the other side of the heat exchange plate 19 is provided with a linear array of heat exchange slots 20. The cooling pipe 13 is in contact with the inner wall of the heat exchange slot 20.

[0034] like Figure 1 and Figure 2 As shown, a servo motor 8 is installed on the first mold 2. The output shaft of the servo motor 8 is fixedly connected to the top of the threaded rod 17. The servo motor 8 is electrically connected to the power supply.

[0035] Working principle: When injection molding is performed using the first mold 2 and the second mold 3, the servo motor 8 drives the threaded rod 17 to rotate, which causes the heating plate 6 to descend into the hot and cold cavity 5. Then, the heating tube 10 heats the inside of the hot and cold cavity 5, and the heat conduction plate 18 conducts heat to the surface wall of the mold cavity 4. In this way, the material in the mold cavity 4 is heated, which facilitates material flow and injection molding.

[0036] After injection molding, the threaded rod 17 is rotated in the opposite direction, so that the heating plate 6 slides into the top insulation cavity 16 for insulation, while the cooling plate 7 moves into the hot and cold cavity 5. The cooling water in the water tank 15 is brought into the refrigerator 14 by the water pump for cooling. The cooled water is delivered to the cooling pipe 13, and the cooling pipe 13 is used to exchange heat with the heat exchange plate 19, thus completing the cooling of the heat exchange plate 19. The heat exchange plate 19 absorbs the heat from the inner wall of the mold cavity 4 and cools the material in the mold cavity 4, thereby facilitating the rapid cooling and molding of the material. After the cooling water exchanges heat, it flows back into the water tank 15.

[0037] When the heating plate 6 is in use, the cooling plate 7 moves to the bottom insulation cavity 16. The inner wall of the insulation cavity 16 is made of heat-insulating material or coated with heat-insulating coating to insulate the cooling plate 7 and prevent external heat from affecting the cooling plate 7, so as to ensure the internal temperature of the cooling plate 7. Conversely, the heating plate 6 moves to the top insulation cavity 16 to insulate the heating plate 6.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
