Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, and in particular to a molding equipment that is easy to maintain. Background Technology

[0002] Molding equipment generally refers to mechanical equipment used for molding plastic products, mainly including injection molding machines, blow molding machines, and extruders. During operation, injection molding machines typically have internal molding dies, which usually consist of two parts: a moving mold and a fixed mold. The moving mold is mounted on the moving platen of the injection molding machine, and the fixed mold is mounted on the fixed platen. During injection molding, the moving and fixed molds close to form the gating system and cavity; when the mold opens, the moving and fixed molds separate to remove the plastic product.

[0003] For vertical injection molding machines, when assembling and disassembling the molding die, it is inconvenient to use the bridge crane in the workshop to lift it due to the obstruction of the injection molding machine. Usually, a lift truck or forklift is used to lift it to a certain height, and then it is manually pushed into the worktable of the injection molding machine. This not only makes the assembly and disassembly time-consuming and labor-intensive, reducing maintenance efficiency, but also poses certain dangers and affects production safety. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the assembly and disassembly of molding molds are inconvenient, affecting maintenance efficiency and posing certain dangers during assembly and disassembly, and to propose a molding equipment that is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A molded molding device that is easy to maintain includes an injection molding machine. A worktable is fixedly mounted on the injection molding machine, and a lower mold is detachably mounted on the worktable. A mounting plate is lifted and lowered on the injection molding machine, and an upper mold that matches the lower mold is detachably mounted on the bottom of the mounting plate. The device also includes a movable seat that is slidably mounted on the worktable, with the top end face of the worktable higher than the top end face of the movable seat. A lifting block for lifting the mold is lifted and lowered on the movable seat, and a lifting part for driving the lifting block to rise and fall is provided on the movable seat.

[0007] To ensure reliable sliding of the movable seat, preferably, a T-shaped guide groove is provided on the worktable, the movable seat is slidably disposed in the guide groove, and the guide groove extends to the bottom of the lower mold.

[0008] To facilitate the lifting and lowering of the top block and reduce skew, preferably, the movable seat is provided with a lifting groove, the top block is lifted and lowered in the lifting groove, and the top end face of the top block is flush with the top end face of the movable seat.

[0009] Furthermore, limit grooves are fixedly provided on both sides of the inner wall of the lifting groove, and limit blocks are fixedly provided on both sides of the top block, with the limit blocks slidably connected to the limit grooves.

[0010] To facilitate the lifting and lowering of the top block, the lifting unit further includes an inclined guide block slidably disposed in the lifting groove. The top block has an inclined guide groove, and the inclined guide block is slidably connected to the inclined guide groove. When the inclined guide block slides, the top block rises or falls.

[0011] Furthermore, a rotating shaft is rotatably mounted on the movable seat, and a lead screw is fixedly mounted at one end of the rotating shaft extending into the lifting groove. The inclined guide block is threadedly connected to the lead screw, and a handle is fixedly mounted at the other end of the rotating shaft.

[0012] Compared with the prior art, this utility model provides a molding equipment that is easy to maintain and has the following beneficial effects:

[0013] 1. This easy-to-maintain molding equipment allows the mold to be lifted by rotating the shaft and driving the lead screw to slide the inclined guide block in the inclined guide groove. Then, the moving seat can be slid to bring the mold to the open area of ​​the worktable for easy hoisting. This not only reduces assembly and disassembly time and improves maintenance efficiency, but also enhances safety.

[0014] 2. This easy-to-maintain molding equipment has a guide groove on the worktable, in which the moving seat is slidably set. This not only ensures the reliable sliding of the moving seat, but also reduces the direct friction between the bottom end face of the mold and the top end face of the worktable after the top block lifts the mold. This helps to maintain the roughness of the mating end faces and improves the service life of the mold and the worktable.

[0015] All parts not mentioned in this device are the same as or can be implemented using existing technology. This utility model removes the mold from the workbench and mounting plate respectively. By rotating the shaft, the lead screw drives the inclined guide block to slide in the inclined guide groove, which can lift the top block to a certain height and realize the lifting of the mold. Then, the moving seat is slid to bring the mold to the open area of ​​the workbench, which is convenient for hoisting the mold. This not only reduces the assembly and disassembly time and improves maintenance efficiency, but also improves the safety of use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Reference Figures 1-4A molded molding device that is easy to maintain includes an injection molding machine 1, which is a vertical structure. A worktable 101 is fixedly mounted on the injection molding machine 1. A lower mold is detachably mounted on the worktable 101. A mounting plate 103 is raised and lowered on the injection molding machine 1. An upper mold matching the lower mold is detachably mounted at the bottom of the mounting plate 103. The mounting plate 103 can be raised and lowered by a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic cylinder, preferably a hydraulic cylinder. Multiple guide columns are fixedly mounted on the worktable 101, with two to six guide columns, preferably four. The mounting plate 103 is connected to the guides by a sliding sleeve. The column sliding connection ensures reliable lifting and lowering of the mounting plate 103. Furthermore, both the lower and upper molds are bolted to the workbench 101 and the mounting plate 103. The length of the mounting plate 103 is less than the length of the workbench 101. During use, the mold can be lifted onto the workbench 101 using a bridge crane in the workshop, and then directly pushed into the workbench 101 to install the mold. During installation, first, the lower mold, in its closed state, is fixed to the workbench 101. Then, the mounting plate 103 is driven to slide downwards until its bottom end face abuts against the top end face of the upper mold. At this point, the upper mold is fixed. After being fixed on the mounting plate 103, the mounting plate 103, along with the upper mold, rises. Similarly, during disassembly, the mounting plate 103, along with the upper mold, first descends to close with the lower mold. After the mold is closed, the bolts fixing the mold are removed, the mounting plate 103 rises, and then the entire assembly is pulled out from under the mounting plate 103. A bridge crane is used to lift the entire assembly away, achieving rapid assembly and disassembly, improving maintenance efficiency, and enhancing safety. The assembly also includes a sliding seat 2 on the workbench 101, with the top surface of the workbench 101 higher than the top surface of the sliding seat 2, which reduces the risk of damage during the installation of the lower mold. The unevenness of the top of the movable seat 2 prevents interference with the lower mold. Ensuring the flatness between the lower mold and the worktable 101 not only improves installation accuracy but also reduces the machining accuracy of the movable seat 2, thus lowering usage costs. The movable seat 2 is equipped with a lifting block 3 for lifting the mold. After the mold is disassembled from the worktable 101, the lifting block 3 is driven to rise, lifting the mold to a certain height and raising it off the worktable 101. Then, the movable seat 2 is pulled to slide on the worktable 101, which can bring the mold out as a whole, facilitating hoisting and improving assembly and disassembly efficiency. The movable seat 2 is equipped with a lifting part for driving the lifting block 3 to rise and fall.

[0025] In use, after the mold is removed from the workbench 101 and the mounting plate 103 respectively, the screw 401 drives the inclined guide block 5 to slide in the inclined guide groove 302 by rotating the shaft 4. This can lift the top block 3 to a certain height, thereby raising the mold. Then, the moving seat 2 is slid to bring the mold to the open area of ​​the workbench 101, which is convenient for hoisting the mold. This not only reduces the assembly and disassembly time and improves maintenance efficiency, but also improves the safety of use.

[0026] Reference Figure 2 and Figure 3 A T-shaped guide groove 102 is provided on the worktable 101. The movable seat 2 is slidably disposed in the guide groove 102, and the guide groove 102 extends to the bottom of the lower mold. In use, by providing the guide groove 102 on the worktable 101 and slidably disposing of the movable seat 2 in the guide groove 102, not only can the movable seat 2 be reliably slid, but also after the top block 3 lifts the mold, the direct friction between the bottom end face of the mold and the top end face of the worktable 101 is reduced, which helps to maintain the roughness of their mating end faces and improve the service life of the mold and the worktable 101.

[0027] Reference Figure 3 and Figure 4 A lifting groove 201 is provided on the movable seat 2. The top block 3 is lifted and positioned in the lifting groove 201, and the top end face of the top block 3 is flush with the top end face of the movable seat 2, or the top end face of the top block 3 is lower than the top end face of the movable seat 2. Similarly, in order to prevent the top block 3 from interfering with the mold during mold installation, the lifting groove 201 is provided on the movable seat 2, and the top block 3 is lifted and positioned in the lifting groove 201 during use. This ensures that the top block 3 can be lifted and lowered reliably, improving the performance. Limiting grooves 202 are fixedly provided on both sides of the inner wall of the lifting groove 201, and limiting blocks 301 are fixedly provided on both sides of the top block 3. The limiting blocks 301 are slidably connected to the limiting grooves 202, which can further improve the lifting effect and reduce the possibility of the top block 3 tilting during lifting.

[0028] Reference Figure 3 and Figure 4 The lifting plate can be driven by a cylinder, hydraulic cylinder, or electric telescopic cylinder to directly lift the top block 3, or drive the inclined guide block 5 to slide back and forth to lift the top block 3. Here, based on actual use, we design the lifting part to slide the inclined guide block 5 in the lifting groove 201, and the top block 3 is provided with an inclined guide groove 302. The inclined guide block 5 is slidably connected to the inclined guide groove 302. When the inclined guide block 5 slides, the top block 3 rises or falls. In use, by driving the inclined guide block 5 to slide in the lifting groove 201, and through the cooperation of the inclined guide block 5 and the inclined guide groove 302, the top block 3 can be driven to rise and fall, thereby lifting the mold and making it easy to slide the mold on the worktable 101, thus improving the use effect.

[0029] Reference Figures 2-4A rotating shaft 4 is rotatably mounted on the movable seat 2. A lead screw 401 is fixedly mounted at one end of the rotating shaft 4 that extends into the lifting groove 201. The inclined guide block 5 is threadedly connected to the lead screw 401. A handle 402 is fixedly mounted at the other end of the rotating shaft 4. In use, the rotating shaft 4 and the lead screw 401 are rotated by the handle 402, which can drive the inclined guide block 5 to slide along the axis of the lead screw 401. During the sliding process, under the action of the inclined guide groove 302, the top block 3 can be driven to rise and fall, thereby lifting the mold and making it easier to slide on the worktable 101, thus improving the usage effect.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
