Detailed Embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to the attached Figures 1-4, an embodiment provided by the present utility model: an integrally injection-molded mold for a bucket with a handle and a lid, including a panel 1, a bottom plate 20, a first front mold core 4, a second front mold core 5, a first rear mold core 12, and a second rear mold core 13. The first front mold core 4 or the first rear mold core 12 is designed to form the bucket body 7 and the handle 8, and its structure can accurately shape the integrated connection of the bucket body 7 and the handle 8 during the injection molding process, ensuring the firm combination of the bucket body 7 and the handle 8. The second front mold core 5 or the second rear mold core 13 is used to form the bucket lid 9, and through a reasonable cavity design, the sealing performance and stability of the bucket lid 9 are ensured. The first front mold core 4 and the second front mold core 5 are installed on the manifold backing plate 3, and the manifold backing plate 3 is located between the first front mold core 4 and the panel 1, playing a role in evenly distributing the plastic melt and ensuring the quality of the injection-molded product. The first rear mold core 12 and the second rear mold core 13 are installed on the rear template 14, and the rear template 14 is located between the first rear mold core 12 and the bottom plate 20, providing support and fixation functions to ensure the precise alignment of the mold and the dimensional stability of the finished product.
[0020] A first ejector plate 17, a second ejector plate 18, and a third ejector plate 19 are sequentially installed between the rear template 14 and the bottom plate 20. These three ejector plates are respectively used to control the demolding actions of the finished products at different parts in the mold, ensuring that the bucket body 7, the handle 8, and the bucket lid 9 can be smoothly separated from the mold. The arrangement of the ejector plates can evenly distribute the ejection force, preventing the product from deforming or being damaged during the demolding process. In addition, square iron 16 is provided on both sides of the ejector plates. Through a stable structural design, the square iron strengthens the rigidity and durability of the ejector plates, and provides additional support during the ejection process, further improving the working accuracy and durability of the mold.
[0021] Guide pillars 6 are evenly distributed at the four top corners of the panel 1. These guide pillars 6 penetrate the manifold backing plate 3 in a precisely positioned manner and are closely fitted with the concave holes at the four corners of the rear template 14. The design of the guide pillars 6 is not only used to ensure the precise alignment of the upper and lower molds during the mold closing and opening processes, preventing the mold from shifting, but also plays a role in stabilizing the mold structure, ensuring the high precision and consistency of the bucket body 7, the handle 8, and the bucket lid 9 during the injection molding process. In addition, the penetrating structure of the guide pillars 6 enhances the overall rigidity of the mold, effectively reducing the possible deviation during the mold operation and ensuring the quality of the finished product.
[0022] Two second front mold cores 5 and two first front mold cores 4 are precisely arranged on the diverter pad 3 so as to realize the simultaneous molding of different parts in one injection process. Each second front mold core 5 is provided with a barrel cover flow channel 501, which is used to guide the molten plastic into the mold cavity of the barrel cover to ensure that the plastic is evenly distributed and form a barrel cover with precise size and complete structure. Similarly, the first front mold core 4 is designed with a handle flow channel 401, which is specifically responsible for guiding the molten plastic to the mold cavity of the handle, so that the injection molding process of the handle can proceed smoothly. Through the reasonable design and distribution of these flow channels, the mold can efficiently and accurately mold three parts in one injection process, ensuring the production efficiency and quality of the product.
[0023] Two first rear mold cores 12 and two second rear mold cores 13 are precisely arranged on the rear mold plate 14, so that they can cooperate with the front mold core to realize injection molding of complex structures. Each first rear mold core 12 is specially designed with a mold cavity 1201 for molding the barrel body. This mold cavity ensures that the shape and size of the barrel body 7 can fully meet the design requirements. At the same time, a precisely positioned cavity 1301 is provided in the second rear mold core 13, which is used to form the structure of the barrel cover 9. The design of the cavity 1301 enables the barrel cover 9 to accurately match the barrel body during the molding process, ensuring the sealing and practicality of the final product.
[0024] The first front mold core 4 and the first rear mold core 12 cooperate closely to form a special cavity for making the barrel body 7 and the handle 8. This cavity design ensures the structural strength and appearance consistency of the barrel body 7 and the handle 8. At the same time, the second front mold core 5 and the second rear mold core 13 match each other to form a special cavity for making the barrel cover 9. Through these precise mold core cooperation and cavity design, the mold can simultaneously form the barrel body 7, the handle 8 and the barrel cover 9 in a single injection process, which greatly improves the production efficiency and ensures the high quality and consistency of the final product.
[0025] The first front mold core 4 and the first rear mold core 12 are matched with each other to form a cavity for making the barrel body 7 and the handle 8, and the second front mold core 5 and the second rear mold core 13 are matched with each other to form a cavity for making the barrel cover 9.
[0026] The first ejector plate 17 and the second ejector plate 18 are firmly connected by a T-shaped lock 21. This design not only ensures the stability of the ejector plate, but also facilitates the precise operation and positioning of the ejector plate during the injection molding process. The third ejector plate 19 is connected to the bottom plate 20 by a U-shaped guide 22, so that the two can maintain precise sliding fit when the mold is opened and closed, ensuring the smoothness and reliability of the mold operation. The sliding matching relationship between the T-shaped lock 21 and the U-shaped guide 22 further improves the overall coordination and precision of the mold system.
[0027] In addition, guide sleeves 15 are designed at both ends of the square iron 16. These guide sleeves 15 pass through the rear template 14, providing additional guidance and support to ensure the precise alignment and stability of each component of the mold during the injection molding process.
[0028] The mold is installed on the front and rear plates of the injection molding machine as follows:
[0029] First, the first front mold core 4 for forming the barrel body and the handle and the second front mold core 5 for forming the barrel lid are positioned by positioning pins and fixed to the runner backing plate 3 with screws. Subsequently, the panel 1, the runner support plate 2, and the runner backing plate 3 are sequentially positioned by positioning pins and fixed with screws to form the integral front mold. Then, the first ejector plate 10, the second ejector plate 11, the first rear mold core 12, and the second rear mold core 13 are positioned by positioning pins and fixed to the rear template 14 with screws. Next, the rear template 14, the square iron 16, the first ejector pin plate 17, the second ejector pin plate 18, the third ejector pin plate 19, and the bottom plate 20 are sequentially positioned by positioning pins and fixed integrally with screws to form the integral rear mold. The front mold and the rear mold are combined to form a set of integral molds. The panel 1 is locked to the front plate of the injection molding machine, and the bottom plate 20 is locked to the rear plate of the injection molding machine.
[0030] The molding steps are as follows: After the injection molding machine closes the mold, the first front mold core 4, the second front mold core 5, the first ejector plate 10, the second ejector plate 11, the first rear mold core 12, and the second rear mold core 13 are locked together to form three injection cavities for forming the barrel body 7, the handle 8, and the barrel lid 9 respectively.
[0031] The injection molding machine injects the molten plastic into the main gate in the mold through the injection device. The timing controller precisely controls the flow direction of the valve needle gate and the injection volume of each product to ensure that the three cavities of the barrel body 7, the handle 8, and the barrel lid 9 are injection-molded at the same time. After the injection molding is completed, cold cutting and forming are carried out through the cooling system of the mold. Finally, the ejector rod of the injection molding machine drives the ejector pin plate to eject the molded product from the mold. After the ejector pin plate returns to its original position, the production cycle of a one-piece molded product of the barrel body 7, the handle 8, and the barrel lid 9 is completed.
