Description

Technical Field

[0001] This utility model relates to the field of polyurethane product molding technology, and in particular to a polyurethane elastomer bushing casting tool. Background Technology

[0002] Polyurethane elastomer bushings, as an important industrial component, are widely used in various mechanical equipment due to their excellent wear resistance, shock absorption, and impact resistance. In their manufacturing process, liquid casting is the mainstream method, which involves injecting the mixed polyurethane liquid raw material into a pre-designed mold, allowing it to solidify, and then demolding to form the final product.

[0003] During the casting process, to ensure that the polyurethane liquid completely fills the complex cavity of the mold and effectively removes air bubbles generated during material mixing, it is often necessary to tilt the entire mold at a certain angle. This usually requires placing the mold body on an external tilting device or support. However, a mating interface is formed between the mold body and the tilting device, and the stability of this interface directly affects the success or failure of the entire casting process.

[0004] In current practice, many casting fixtures lack a dedicated and reliable locking structure between the mold body and the tilting device. During operation, the mold body is often simply placed within the frame of the tilting device, relying on its own weight and friction to maintain its position. When the tilt angle is large or vibration occurs during operation, the mold body can easily slide or misalign within the frame, and there is even a risk of it slipping off the tilting device. This unstable fixing method not only seriously affects the quality and consistency of the cast products, but also poses significant safety hazards to on-site operators, while also reducing production efficiency.

[0005] Therefore, this utility model proposes a polyurethane elastomer bushing casting fixture to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a polyurethane elastomer bushing casting fixture, which aims to improve the problem of low operational reliability caused by the unstable fixing of the mold body and tilting device and easy slippage in the existing polyurethane elastomer bushing casting fixture.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a polyurethane elastomer bushing casting fixture, comprising: a mold body and an inclined assembly, wherein the outer wall of the mold body is provided with a locking hole, and a locking assembly is also included; The tilting component includes an outer frame for accommodating the mold body, and a first leg and a second leg are fixedly connected to the bottom of the outer frame. The locking assembly is installed on the side wall of the outer frame. The locking assembly includes a sliding post, a limiting plate, a spring, and a handle. The sliding post slides through the outer frame, and one end of the sliding post is used to engage with the locking hole. The handle is fixedly connected to the other end of the sliding post. The limiting plate is fixedly connected to the outer wall of the sliding post. The spring is sleeved on the sliding post and is located between the limiting plate and the inner wall of the outer frame.

[0008] Preferably, the polyurethane elastomer bushing casting fixture further includes a cap, which is detachably installed on the top of the mold body.

[0009] Preferably, the mold body has a pouring groove inside, and the outer wall of the cover has a pouring port, which is connected to the pouring groove.

[0010] Preferably, a connecting block is fixedly connected to the outer wall of the cover.

[0011] Preferably, a connecting plate is fixedly connected to the outer wall of the mold body.

[0012] Preferably, the first leg and the second leg are spaced apart at the bottom of the outer frame.

[0013] Preferably, the sliding column is horizontally slidably inserted through the outer frame.

[0014] Preferably, the limiting plate is vertically fixed to the rod of the sliding column, one end of the spring abuts against the limiting plate, and the other end of the spring abuts against the inner wall of the outer frame.

[0015] Preferably, the handle is located outside the outer frame and passes through the side wall of the outer frame to connect with the sliding column.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting a locking component, the sliding column driven by the spring is engaged with the locking hole on the mold body, which solves the problem that the mold body is easy to slide and unstable in the tilting device in the prior art, and achieves the effect of reliable locking, accurate positioning, and effective prevention of accidental displacement of the mold body during tilting pouring.

[0020] 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.

[0021] Reference Figures 1-6 This utility model provides a polyurethane elastomer bushing casting fixture, which aims to solve the problems of unstable fixing of the mold body and tilting device and inconvenient operation in the prior art.

[0022] Specifically, the system includes a mold body 1 and an inclined assembly 7 disposed below the mold body 1. The mold body 1 is used to accommodate and mold a polyurethane elastomer bushing, while the inclined assembly 7 is used to support the mold body 1 and enable inclined casting. A locking hole 801 is provided on the outer wall of the mold body 1. The inclined assembly 7 includes an outer frame 701, which is used to accommodate the mold body 1. A first leg 702 and a second leg 703 are fixedly connected to the bottom of the outer frame 701. The arrangement of the first leg 702 and the second leg 703 enables the inclined assembly 7 to be stably supported on the working plane, and different angles of tilting can be achieved through different combinations of support points.

[0023] The system also includes a locking assembly 8, which is mounted on the side wall of the outer frame 701. The locking assembly 8 includes a sliding post 802, a limiting plate 803, a spring 804, and a handle 805. The sliding post 802 slides through the side wall of the outer frame 701, and one end of the sliding post 802 is used to extend or retract to engage or disengage with the locking hole 801 on the mold body 1, thereby achieving locking or unlocking. The handle 805 is fixedly connected to the other end of the sliding post 802 away from the locking hole 801. The handle 805 is located outside the outer frame 701 and is used by the operator to pull or release, driving the sliding post 802 to perform axial reciprocating motion.

[0024] The limiting plate 803 is fixedly connected to the outer wall of the sliding column 802 and moves synchronously with the sliding column 802. The spring 804 is sleeved on the sliding column 802 and is located between the limiting plate 803 and the inner wall of the outer frame 701. When the spring 804 is in its normal state, its elastic force pushes the limiting plate 803, thereby driving the sliding column 802 to extend and engage in the locking hole 801, so that the mold body 1 is firmly locked in the outer frame 701. This automatic locking structure of the spring ensures that the mold body 1 will not accidentally slip out during tilting or movement, thus ensuring the stability and safety of the pouring operation.

[0025] To achieve complete mold sealing and material injection, a cap 3 is also included. The cap 3 is detachably installed on the top of the mold body 1 to form a sealed mold cavity. The cap 3 not only prevents polyurethane raw materials from splashing during the pouring process, but also prevents external impurities from falling into the mold and affecting product quality. A sealing gasket can be provided at the connection between the cap 3 and the mold body 1 to enhance the sealing effect and ensure stable pressure inside the mold cavity.

[0026] To guide the material smoothly into the mold cavity, a gating groove 6 is provided inside the mold body 1, while a gating port 4 is provided on the outer wall of the cap 3. In the assembled state, the gating port 4 and the gating groove 6 are interconnected, forming a complete gating channel. Polyurethane raw material can be injected through the gating port 4, and then flows into and fills the entire mold cavity via the gating groove 6. The inlet end of the gating port 4 can be designed in a funnel shape for easy alignment and pouring of the material, reducing waste. The internal channel of the gating groove 6 can be designed with a smooth transition surface to ensure smooth material flow and reduce the generation of air bubbles.

[0027] To facilitate operation and improve structural strength, a connecting block 5 is fixedly connected to the outer wall of the cover 3. The connecting block 5 can be set on the side and rear of the cover 3. It can not only serve as a gripping point when installing and removing the cover 3, making it easier for operators to apply force, but also increase the structural rigidity of the cover 3, preventing the cover 3 from deforming or falling off due to accidental collisions during handling or pouring, thus improving the durability and ease of operation of the tooling.

[0028] To provide additional support points during tilting operations, a connecting plate 2 is fixedly connected to the outer wall of the mold body 1. The connecting plate 2 can be designed as a plate-like structure extending from the left outer wall of the mold body 1. When the tooling needs to be tilted or moved, the operator can hold the connecting plate 2 or use auxiliary clamps to fix the connecting plate 2, providing additional stability and maneuverability for the entire tooling. The connecting plate 2 plays an important auxiliary role, especially in situations where precise control of the tilt angle is required.

[0029] To achieve stable multi-angle tilting, the first leg 702 and the second leg 703 are spaced apart at the bottom of the outer frame 701. The first leg 702 and the second leg 703 can have different lengths or geometric layouts. By using different side edges of the outer frame 701 as fulcrums and supporting them with the first leg 702 or the second leg 703 respectively, the entire fixture can form different and stable tilting angles, such as 30 degrees or 60 degrees. This makes angle adjustment intuitive and quick without the need for external measuring tools.

[0030] To ensure a smooth and direct locking action, the sliding post 802 slides horizontally through the outer frame 701. The horizontal sliding direction corresponds to the orientation of the locking hole 801 on the mold body 1, ensuring that the sliding post 802 can be inserted into or removed from the locking hole 801 without obstruction and with precision. This avoids jamming caused by uneven gravity or friction, and improves the reliability and response speed of the locking mechanism.

[0031] A limiting plate 803 is vertically fixed to the rod of the sliding column 802. The limiting plate 803 is preferably a circular or square plate, providing a stable and uniform force-bearing surface for the spring 804. The spring 804 is preferably a helical compression spring, with one end reliably abutting against the side of the limiting plate 803 and the other end abutting against the inner wall of the outer frame 701. When the handle 805 is pulled, the limiting plate 803 compresses the spring 804, storing elastic potential energy; when the handle 805 is released, the spring 804 releases energy, pushing the limiting plate 803 back to its original position, thereby achieving automatic locking of the sliding column 802.

[0032] The handle 805 is located outside the outer frame 701 and passes through the side wall of the outer frame 701 to connect with the sliding column 802. This design places the operating part outside the device, making it convenient for personnel to lock or unlock at any time. The handle 805 is specifically a T-shaped handle, which is easy for fingers to grip and apply force, improving the user-friendliness of human-machine interaction. The connection between the handle 805 and the sliding column 802 can be a threaded connection or a one-piece molding to ensure a firm and reliable connection.

[0033] Working principle: When in use, first install the tilting component 7 at the bottom of the mold body 1. Then, the connecting plate 2 on the outer wall of the mold body 1 can help maintain stability during pouring in the tilted state. Then, install the cover 3 on the top of the mold body 1. The connecting block 5 fixed on the outer wall of the cover 3 provides a support gripping point for the cover 3 to prevent the cover 3 from falling off during pouring. The pouring port 4 opened on the outer wall of the cover 3 is a pouring channel, and its pouring port 4 is connected to the pouring groove 6 inside the mold body 1.

[0034] When tilting the mold body 1, the outer frame 701 is first installed at the bottom of the mold body 1. The bottom of the outer frame 701 is fixedly connected to the first leg 702 and the second leg 703. The first leg 702 and the second leg 703 are separated by a certain distance. When pouring, the side edge of the outer frame 701 is used as the fulcrum, and the first leg 702 is the bottom fulcrum, so that it can be tilted at an angle of 30° for pouring. When pouring in the range of 60°, the second leg 703 fixed at the bottom of the outer frame 701 is used as the bottom support point, and the tilt angle can be adjusted within the range of 30° to 60° according to the mold structure. When adjusting, the top cover 3 is installed in the opposite direction to ensure that the mold body 1 is in a stable tilted state during pouring. After pouring, the mold body 1 is in a stable flat state.

[0035] The locking component 8 can be used to fix the tilting component 7 during installation, preventing the mold body 1 from sliding on the inner wall of the tilting component 7. During installation, first pull the handle 805, which will cause the sliding column 802 to slide inside the outer frame 701. At the same time, the sliding column 802 will cause the limiting plate 803 fixed on its outer wall to compress the spring 804 inside the outer frame 701. Then, place the mold body 1 inside the outer frame 701, release the handle 805, and the spring 804 will release its elastic potential energy to drive the limiting plate 803 and the sliding column 802 to reset, so that the sliding column 802 is locked into the locking hole 801 opened on the outer wall of the mold body 1, thus preventing the mold body 1 from sliding out from the inner wall of the outer frame 701.
