[0002] Plastic drums are widely used for the storage and transportation of various liquids. They offer excellent packaging properties for special hazardous materials. Made primarily of polyethylene, polypropylene, and polyester through blow molding, injection molding, vacuum forming, or rotational molding, plastic drums are characterized by their resistance to breakage, rust, lightweight, and deformation. They also exhibit good oil and strong corrosion resistance. They are commonly used for packaging hazardous materials requiring insulation, moisture protection, pressure resistance, and corrosion resistance. These drums are primarily used for containing liquids and solids in industries such as chemical raw materials, pesticides, lubricants, coatings, pharmaceuticals, food, hardware, electronics, and electromechanical products. During the production of plastic drums, injection molding is required to produce matching handles.
[0003] In the prior art, most injection molding equipment directly uses ejectors to lift the handle body during demolding. The ejection force is relatively concentrated, and there are usually grooves. During rigid ejection, the material needs to be elastically deformed to make the hook boss detach from the injection groove. However, the structure of the handle hook is relatively delicate, and the elastic deformation process can easily cause the hook to warp, whiten, or even break, which may cause the handle to fall off during subsequent use. Therefore, this utility model provides an injection molding equipment for preventing plastic bucket handles from falling off, in order to solve the above problems. Utility Model Content

[0026] like Figures 1 to 6As shown, this utility model provides a plastic bucket handle anti-detachment injection molding equipment, including: a lower mold structure 1, the lower mold structure 1 including a lower mold base 11, a guide groove 12, a handle injection groove 13, a hook injection groove 14, a lower connecting groove 15 and a slide groove 16, both the lower connecting groove 15 and the slide groove 16 are provided with two sets, both sets of slide groove 16 are provided with a core pulling structure 3 inside, the outer surfaces of both ends of the lower mold base 11 are fixedly connected with mounting bases 17, the middle position of the upper end of the mounting base 17 is installed with a first cylinder 18, the lower end of the push rod inside the first cylinder 18 is provided with an upper mold structure 2, the hook injection groove 14 is provided with two sets, the lower end of the lower mold base 11 is provided with a cavity, and the cavity is provided with a demolding structure 4; The upper mold structure 2 includes an upper mold base 21, an upper connecting groove 25 and an inclined guide post 26. Both the upper connecting groove 25 and the inclined guide post 26 are provided in two sets. The upper surface of the upper mold base 21 is fixedly connected to the lower end of the push rod inside the first cylinder 18. The core-pulling structure 3 is provided in two sets. Each set of core-pulling structure 3 includes a connecting plate 31, a support plate 32 and a blocking plate 33. The two sets of blocking plates 33 are slidably inserted into the interior of the two sets of sliding grooves 16 respectively. The demolding structure 4 includes a guide rod 41, a second cylinder 42, a push plate 43, a center ejector pin 44, an end ejector pin 45, and a hook ejector pin 46. The guide rod 41, the end ejector pin 45, and the hook ejector pin 46 are each provided in two sets. The second cylinder 42 is installed on the lower surface inside the cavity.
[0027] Among them, the guide groove 12 is opened inside the four corners of the upper surface of the lower mold base 11, the handle injection groove 13 is opened inside the middle position of the upper surface of the lower mold base 11, the two sets of hook injection grooves 14 are respectively opened inside the lower surface of the handle injection groove 13, the two sets of lower connecting grooves 15 and sliding grooves 16 are respectively opened inside the upper surface of the lower mold base 11, and the interior of the two sets of sliding grooves 16 is connected to the interior of the two sets of hook injection grooves 14.
[0028] During the injection molding process, when the molten material flows into the handle injection groove 13, it can form the handle body. The molten material can also flow into the two sets of hook injection grooves 14 through the handle injection groove 13 to form the handle hook.
[0029] The upper mold base 21 has an injection tube 23 connected to the inside of one side surface. An injection port 24 is opened in the middle of the lower surface of the upper mold base 21, and the inside of the injection port 24 is connected to the inside of the injection tube 23. Guide posts 22 are fixedly connected to the four corners of the lower surface of the upper mold base 21, and the guide posts 22 are slidably inserted into the inside of the guide groove 12.
[0030] The sliding connection between the guide groove 12 and the guide post 22 can improve the stability of the upper mold structure 2 when it moves as a whole, and avoid deviation when the mold is closed. The injection tube 23 can be connected to an external melt source. After the lower surface of the upper mold base 21 is attached to the upper surface of the lower mold base 11, the melt will flow into the handle injection groove 13 through the injection port 24 for injection molding.
[0031] Among them, two sets of upper connecting grooves 25 are respectively opened inside the lower surface of the upper mold base 21, two sets of inclined guide posts 26 are respectively fixedly connected to the interior of the two sets of upper connecting grooves 25, the positions of the two sets of baffles 33 at opposite ends correspond to the positions inside the two sets of hook injection grooves 14, and semi-circular through grooves are opened inside the surfaces of the two sets of baffles 33 at opposite ends.
[0032] The two sets of baffles 33 can slide horizontally and parallel inside the two sets of slide grooves 16. After the surfaces of the two sets of baffles 33 are attached to each other, a circular through groove can be formed. During the injection molding process, the combination of the hook injection groove 14 and the circular through groove can form the groove and boss of the handle.
[0033] In this arrangement, the upper surfaces of the two sets of baffles 33, which are far apart from each other, are fixedly connected to support plates 32. The upper ends of the two sets of support plates 32 are fixedly connected to connecting plates 31. The positions of the two sets of connecting plates 31 and support plates 32 correspond to the positions inside the two sets of upper connecting grooves 25.
[0034] The opening of two sets of lower connecting grooves 15 and upper connecting grooves 25 can prevent the two sets of core pulling structures 3 and inclined guide pillars 26 from blocking the lower mold structure 1 and the upper mold structure 2 when they are closed, so that the upper surface of the lower mold base 11 can fit tightly with the lower surface of the upper mold base 21, and can prevent the molten material from flowing into the interior of the two sets of lower connecting grooves 15 and sliding grooves 16 during the injection process.
[0035] Among them, two sets of inclined guide posts 26 are slidably inserted into the interior of two sets of connecting plates 31, and the positions of the two sets of inclined guide posts 26 correspond to the positions inside the two sets of lower connecting grooves 15.
[0036] The movement of the upper mold base 21 will cause the two sets of inclined guide pillars 26 to move synchronously. When the two sets of inclined guide pillars 26 move upward, they will cause the two sets of connecting plates 31 to move away from each other. When the two sets of inclined guide pillars 26 move downward, they will cause the two sets of connecting plates 31 to move closer to each other.
[0037] Two sets of guide rods 41 are fixedly connected to the upper surface inside the cavity, the lower surface of the push plate 43 is fixedly connected to the upper end of the push rod inside the second cylinder 42, and the two sets of guide rods 41 are slidably inserted into the inside of the push plate 43.
[0038] By activating the second cylinder 42, the push plate 43 can be moved. The movement of the push plate 43 can be restricted by the setting of two sets of guide rods 41, which can prevent the push plate 43 from shaking when moving.
[0039] The lower end of the central ejector pin 44 is fixedly connected to the middle position of the upper surface of the push plate 43, and the upper end of the central ejector pin 44 is slidably inserted into the middle position of the handle injection groove 13.
[0040] The movement of the push plate 43 can drive the central ejector pin 44 to move synchronously. When the central ejector pin 44 moves upward, it can lift the handle inside the handle injection molding groove 13.
[0041] Two sets of end pins 45 and hook pins 46 are fixedly connected to the two ends of the upper surface of the push plate 43, the upper ends of the two sets of end pins 45 are slidably inserted into the interior of the two sets of hook injection grooves 14, and the upper ends of the two sets of hook pins 46 are slidably inserted into the interior of the two ends of the handle injection groove 13.
[0042] The movement of the push plate 43 can drive the two sets of end ejector pins 45 and hook ejector pins 46 to move upward synchronously. The two sets of hook ejector pins 46 apply a uniform pushing force to both ends of the handle after injection molding in the handle injection groove 13, so as to avoid deformation of the handle body. When the two sets of end ejector pins 45 move upward, the two sets of hook injection groove 14 apply a pushing force to the handle hook after injection molding, so as to avoid deformation of the handle hook during demolding.
[0043] Working principle and usage process of this utility model: The first cylinder 18 is activated to push the upper mold structure 2 downward. At the same time, the two sets of inclined guide pillars 26 slide inside the two sets of connecting plates 31, causing the two sets of core-pulling structures 3 to move closer to each other until the lower surface of the upper mold base 21 is attached to the upper surface of the lower mold base 11. At this time, the two sets of blocking plates 33 are attached at opposite ends to form a circular through groove. Then, through the injection port 24 connected to the injection tube 23, molten material is injected into the handle injection groove 13 and the two sets of hook injection grooves 14 to form the handle and hook. After injection molding is completed, the first cylinder 18 drives the upper mold structure 2 upward, and the inclined guide pillars 26 drive the two sets of core-pulling structures 3 to move away from each other, so that the blocking plates 33 are disengaged from the hook injection grooves 14. Finally, the second cylinder 42 is activated to push the push plate 43 to drive the center ejector pin 44, the two sets of end ejector pins 45 and the two sets of hook ejector pins 46 to push the handle body in the handle injection groove 13 and the hook in the hook injection groove 14 upward, thereby completing the demolding.
[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 18 and the second cylinder 42 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Furthermore, all movable parts in this application need to be cleaned and maintained regularly, including but not limited to dust removal and lubrication, to ensure their normal operation.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
