Description

Technical Field

[0001] This utility model relates to the field of injection molding base technology, and in particular to a double slide rail injection molding base that prevents mold jamming. Background Technology

[0002] The injection base, also known as the lower mold base or mold foot plate, is the basic load-bearing component of the injection mold. It is usually fixed on the moving or fixed mold plate of the injection molding machine, which is equivalent to the "foundation" of the mold. All other functional components are directly or indirectly attached to it. Its core functions include load bearing and fixing, positioning and guiding, assembly and compatibility.

[0003] A search revealed that the document with publication number "CN220499756U" states that "this utility model discloses a support base for injection molds, wherein at least two sets of forklift arm insertion channels extending horizontally are arranged side by side on the base body; a limiting arm is provided for each set of forklift arm insertion channels; the limiting arm includes a rotating part, a first arm, and a second arm; the rotating part is disposed on the base body and can rotate around a central axis extending horizontally; the first arm and the second arm are arranged on opposite sides of the rotating part; the first arm has an abutting end that extends into the forklift arm insertion channel; a lifting eye is threadedly connected to the base body and has a pressing position for pressing down the second arm; in the pressing position, an upper and lower limiting space is formed between the abutting end of the first arm and the forklift arm insertion channel." In use, it can be transferred and transported by both forklifts and lifting equipment. When transported by forklift, the support base and the forklift arm can form an upper and lower limiting fit to effectively prevent the support base from detaching from the forklift arm.

[0004] However, existing injection molding bases are generally designed with a single slide rail. This design makes it difficult to evenly distribute the weight of the mold, leading to localized stress concentration and increasing the risk of mold jamming. In addition, vertical demolding relies on non-forced methods, which cannot solve the problem of mold jamming caused by adhesion. Furthermore, frequent mold jamming will lead to downtime for maintenance, reducing production efficiency and increasing manual intervention costs.

[0005] Therefore, we provide a dual-slide-rail injection molding base that prevents mold jamming to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a double-slide-rail injection molding base that prevents mold jamming, aiming to solve the problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A double-slide rail injection molding base for preventing mold jamming includes an automated mounting plate. A linear guide rail is mounted on the upper end of the automated mounting plate. A sliding component is disposed above the linear guide rail. The sliding component includes a connecting plate disposed above the linear guide rail. A slider is fixedly connected to the front side of the connecting plate. A mold fixing plate is disposed above the connecting plate.

[0008] As a further description of the above technical solution: The inner side of the automated mounting plate is provided with a lifting cylinder, and the surface of the automated mounting plate is provided with a groove. The upper surface of the linear guide rail near the automated mounting plate is provided with a through hole.

[0009] As a further description of the above technical solution: The left end of the linear guide is fixedly connected to a fixed bracket, and a hydraulic cylinder is installed at the upper end of the fixed bracket. The fixed bracket is made of angle steel, and a triangular reinforcing block is fixedly connected to the inner side of the fixed bracket.

[0010] As a further description of the above technical solution: The output end of the hydraulic cylinder is fixedly connected to a snap-fit ​​block, which is a T-shaped block. The surface of the mold fixing plate is provided with a T-shaped groove on the side near the hydraulic cylinder, and the snap-fit ​​block fits into the T-shaped groove on the surface of the mold fixing plate.

[0011] As a further description of the above technical solution: There are four sets of sliders, and the sliders are slidably connected to the surface of the linear guide rail. The mold fixing plate pushes the sliders to move linearly along the linear guide rail under the action of the hydraulic cylinder.

[0012] As a further description of the above technical solution: The surface of the mold fixing plate is provided with a through hole, and the output end of the lifting cylinder passes through the groove opened on the surface of the automatic mounting plate, enters the through hole opened on the surface of the linear guide, and extends upward through the through hole on the surface of the mold fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up sliding components and forming a rigid transmission chain through layered connections, the mold fixing plate moves synchronously with the slider, simplifying the structure and reducing fit errors. The four sets of sliders evenly distribute the weight and force of the mold and the fixing plate, avoiding single-point jamming. In conjunction with the linear guide rail, precise guidance is achieved, ensuring the dimensional accuracy and appearance consistency of parts, reducing product defects. At the same time, the through hole design of the mold fixing plate can accurately align with the holes of the automated mounting plate and the linear guide rail at designated positions, providing a vertical channel for the lifting cylinder, assisting in vertical demolding, reducing the risk of manual intervention, and further avoiding the hidden danger of mold jamming.

[0014] 2. By setting up lifting cylinders and hydraulic cylinders, the hydraulic cylinders form a rigid connection with the mold fixing plate through T-shaped clamping blocks, ensuring accurate transmission of horizontal thrust. Combined with the high thrust characteristics, it is suitable for heavy-duty scenarios. With the help of angle steel fixing brackets and triangular reinforcement blocks, it resists reaction forces and prevents axis deviation, avoiding mold jamming and product defects caused by insufficient power or deviation. The lifting cylinder can quickly and vertically lift the mold after the mold is positioned, forcibly separating the product from the mold, directly solving the problem of sticking and jamming. Moreover, non-contact demolding can protect the mold and product, reduce damage and deformation, and improve production efficiency and product yield. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 As shown, this utility model provides a technical solution: a double slide rail injection molding base for preventing mold jamming, including an automated mounting plate 1, a linear guide rail 3 mounted on the upper end of the automated mounting plate 1, a sliding component 7 disposed above the linear guide rail 3, the sliding component 7 including a connecting plate 701 disposed above the linear guide rail 3, a slider 702 fixedly connected to the front side of the connecting plate 701, and a mold fixing plate 703 disposed above the connecting plate 701.

[0019] Furthermore, a snap-fit ​​block 6 is fixedly connected to the output end of the hydraulic cylinder 5, and the snap-fit ​​block 6 is a T-shaped block. A T-shaped groove is opened on the surface of the mold fixing plate 703 near the hydraulic cylinder 5, and the snap-fit ​​block 6 fits into the T-shaped groove on the surface of the mold fixing plate 703. The T-shaped snap-fit ​​block 6 is fixed at the output end of the hydraulic cylinder 5, and a T-shaped groove is machined on the surface of the mold fixing plate 703 near the cylinder. The snap-fit ​​block 6 is embedded in the T-shaped groove of the mold fixing plate 703. By utilizing the anti-detachment characteristics of the T-shaped structure, a stable connection between the two is achieved, realizing a rigid connection between the hydraulic cylinder 5 and the mold fixing plate 703, ensuring that the horizontal thrust output by the hydraulic cylinder 5 can be accurately transmitted to the mold fixing plate 703.

[0020] Furthermore, four sets of sliders 702 are provided, and the sliders 702 are slidably connected to the surface of the linear guide rail 3. Under the action of the hydraulic cylinder 5, the mold fixing plate 703 pushes the sliders 702 to move linearly along the linear guide rail 3. The sliding cooperation between the four sets of sliders 702 and the linear guide rail 3 disperses the weight and force of the mold fixing plate 703, reduces the frictional resistance at a single point, and combined with the thrust of the hydraulic cylinder 5, realizes the smooth linear movement of the mold fixing plate 703 along the linear guide rail 3, thus structurally avoiding mold jamming.

[0021] Furthermore, the surface of the mold fixing plate 703 is provided with a through hole, and the output end of the lifting cylinder 2 passes through the slot opened on the surface of the automated mounting plate 1, enters the through hole opened on the surface of the linear guide 3, and extends upward through the through hole on the surface of the mold fixing plate 703. When the mold fixing plate 703 is pushed by the hydraulic cylinder 5 to align the central axes of the slot of the automated mounting plate 1, the through hole of the linear guide 3, and the through hole of the mold fixing plate 703, the lifting cylinder 2 is started, and its output end passes through the through hole in sequence and extends upward. Then, the output end of the lifting cylinder 2 lifts the mold on the surface of the mold fixing plate 703 in the vertical direction to prevent the mold from jamming.

[0022] Furthermore, a lifting cylinder 2 is provided on the inner side of the automated mounting plate 1, and a groove is opened on the surface of the automated mounting plate 1. A through hole is opened on the upper surface of the linear guide rail 3 near the automated mounting plate 1. The automated mounting plate 1 is used to install automated devices. At the same time, the groove on the surface of the automated mounting plate 1 and the through hole on the upper surface of the linear guide rail 3 near the automated mounting plate 1 ensure that the output end of the lifting cylinder 2 can smoothly pass through the two layers of components and reach the upper mold fixing plate 703, and then lift the mold above the mold fixing plate 703.

[0023] Furthermore, a fixed bracket 4 is fixedly connected to the left end of the linear guide rail 3, and a hydraulic cylinder 5 is installed on the upper end of the fixed bracket 4. The fixed bracket 4 is made of angle steel, and a triangular reinforcing block is fixedly connected to the inner side of the fixed bracket 4. The fixed bracket 4, made of angle steel, provides stable support for the hydraulic cylinder 5. The triangular reinforcing block further enhances the strength of the bracket, ensuring that the bracket will not deform when the cylinder outputs power, thus ensuring the stability of power transmission.

[0024] Working principle: Initially, the mold is installed above the mold fixing plate 703, and the hydraulic cylinder 5 is in the retracted state. Its output end's locking block 6 is embedded in the T-slot of the mold fixing plate 703, maintaining a rigid connection. The lifting cylinder 2 is also in the retracted state. After starting the hydraulic cylinder 5, its output end drives the mold fixing plate 703 to move via the locking block 6. The four sets of sliders 702 below the mold fixing plate 703 slide along the surface of the linear guide rail 3, achieving smooth horizontal movement. When the mold fixing plate 703 moves to the designated position, the automatic installation is complete. When the central axes of the groove on the surface of plate 1, the through hole of the linear guide rail 3, and the through hole of the mold fixing plate 703 are aligned, the lifting cylinder 2 is activated. Its output end passes through the groove and through hole in sequence and extends upward, vertically lifting the mold above the mold fixing plate 703 to prevent mold jamming. After the mold is lifted, the output end of the lifting cylinder 2 retracts and resets. Then the hydraulic cylinder 5 retracts, and through the locking block 6, it drives the mold fixing plate 703 and the slider 702 to reset along the linear guide rail 3. This completes the use process of a double slide rail injection base for preventing mold jamming.
