Description

Technical Field

[0001] This utility model relates to the field of extrusion die technology, and in particular to a multi-layer supply split adjustable corrugated tile extrusion die. Background Technology

[0002] Extrusion molds are core tools used to process molten or semi-molten materials (such as plastics, metals, rubber, etc.) into continuous profiles or hollow products through extrusion molding. Their core function is to control the material flow path through a precisely designed cavity and flow channel system to achieve high-precision and high-efficiency molding processing. Extrusion molds are commonly used in the production of corrugated tiles. Corrugated tile extrusion molds are used to process molten materials (such as PVC, PC, etc.) into corrugated tiles through extrusion molding. Corrugated tile extrusion molds usually adopt a multi-layer supply split adjustable design, with the covering material covering both sides of the main material, so that the covered main material is gradually squeezed to form corrugated tiles.

[0003] After prolonged use, the surface roughness of the internal distributor or flow equalization guide column of the corrugated tile extrusion die may increase due to friction, affecting the uniformity of the coating material flow. In other words, local eddies may form at the worn parts, causing the coating material to accumulate or stop flowing on the surface of the main material, making it impossible to uniformly coat the main material and affecting the final product quality of the extruded corrugated tile.

[0004] To address this, a multi-layer supply split adjustable corrugated tile extrusion die is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer supply split adjustable corrugated tile extrusion mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer supply split adjustable corrugated tile extrusion mold, including a mold body and an extrusion port provided on the mold body, wherein the mold body is provided with a plurality of equal distribution pipes; the bottom end of the equal distribution pipe is provided with a uniform material discharge component, the uniform material discharge component is used to uniformly distribute the coating material to the outer layer of the main material, the uniform material discharge component includes an upper guide plate, a middle guide plate and a lower guide plate provided in the mold body, and the top of the upper guide plate, the middle guide plate and the lower guide plate are all provided with a flow plate and a pusher plate.

[0007] Preferably, the upper guide plate, middle guide plate and lower guide plate are fixedly installed in the mold body in an inclined manner from top to bottom.

[0008] Preferably, a plurality of flow dividers are fixedly connected to the upper, middle and lower flow dividers, and the discharge pipes connected to the bottom of the flow dividers correspond to the intervals between the flow dividers.

[0009] Preferably, the top of the upper guide plate, the middle guide plate and the lower guide plate are all provided with a barrier block, and the barrier block is installed and connected to the mold body, and the flow plate is slidably connected to the barrier block.

[0010] Preferably, a protective cover is fixedly installed on the mold body, an electric push rod is fixedly installed in the protective cover, and the electric push rod is fixedly connected to the flow plate. The gap between the bottom end of the flow plate and the upper guide plate is a drainage groove.

[0011] Preferably, the barrier block has a limiting groove, the mold body has a threaded rod rotatably connected to it, the threaded rod is threadedly connected to the push plate, and the push plate is slidably connected in the limiting groove.

[0012] Preferably, a motor is fixedly installed on the mold body, and the output shaft of the motor is fixedly connected to a threaded rod. The threaded rod extends to the outside of the mold body, and a gear is fixedly connected to the threaded rod, with a chain connecting the gears.

[0013] The beneficial effects of this utility model are: This invention, by setting up a uniform material discharge component, enables the coating material to be evenly transported between the barrier block and the lower guide plate during use, while the main material is evenly fed between the barrier block and the middle guide plate. Under the pushing action of the pusher plate, areas where the main material or coating material may be excessively piled up can be pushed to areas with less accumulation, further ensuring that the coating material or main material is in a more uniform state. This uniform state is maintained through the discharge channel. With the different positions of the upper, middle, and lower guide plates, the main material on the middle guide plate gradually and evenly flows to the top of the coating material on the lower guide plate, forming a coating material covering the bottom outer layer of the main material. Subsequently, as the coating material on the upper guide plate evenly flows to the top of the main material, it forms a coating material covering both the upper and lower outer layers of the main material. Thus, the entire device enables the coating material to evenly coat the outer layer of the main material. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 6As shown in the figure, a specific embodiment of this utility model provides a multi-layer supply split adjustable corrugated tile extrusion mold, including a mold body 1 and an extrusion port 2 provided on the mold body 1. The mold body 1 is provided with a plurality of equal distribution pipes 3. The bottom end of the equal distribution pipes 3 is provided with a uniform material discharge component. The uniform material discharge component is used to ensure that the coating material is evenly distributed and discharged to the outer layer of the main material. In the production process of corrugated tiles extruded by the mold body 1, the coating material cannot evenly coat the main material and cannot evenly cover the outer layer of the main material, thereby affecting the quality of the finished corrugated tiles. By setting the uniform material discharge component, the coating material can be more evenly coated on the outer layer of the main material during the flow to the outer layer of the main material, preventing the coating material from accumulating or being lacking in certain areas on the outer layer of the main material. The uniform material discharge component is used to ensure that the coating material is evenly distributed and discharged to the outer layer of the main material. The uniform material discharge component includes an upper guide plate 4, a middle guide plate 5 and a lower guide plate 6 provided in the mold body 1. The top of the upper guide plate 4, the middle guide plate 5 and the lower guide plate 6 are all provided with a flow plate 7 and a pusher plate 8.

[0020] like Figures 2 to 4As shown, specifically, the upper guide plate 4, middle guide plate 5, and lower guide plate 6 are fixedly installed in the mold body 1 in an inclined manner from top to bottom. The upper guide plate 4 and lower guide plate 6 are used for the discharge of the coating material, serving as the path panel for the flow of the coating material. The length of the lower guide plate 6 is greater than the length of the upper guide plate 4, and the length of the upper guide plate 4 is greater than the length of the middle guide plate 5. Therefore, in the subsequent material discharge process, the main material discharged from the middle guide plate 5 will fall onto the surface of the coating material on the lower guide plate 6 first, thus forming a combination of coating material covering the bottom surface of the main material. Subsequently, the upper guide plate 4... The coating material falls downwards in the final step, landing on the combination of the coating material and the main material. At this point, the upper surface of the main material is coated, forming the final material combination with the main material in the middle layer and the coating material on the top and bottom outer layers. Several diversion plates 9 are fixedly connected to the upper guide plate 4, the middle guide plate 5, and the lower guide plate 6. The discharge pipes connected to the bottom of the distribution pipe 3 correspond to the intervals between the diversion plates 9. The top of the upper guide plate 4, the middle guide plate 5, and the lower guide plate 6 are all equipped with a baffle block 10, and the baffle block 10 is installed and connected to the mold body 1. The flow plate 7 is slidably connected to the baffle block. In the mold body 1, when in use, the equalizing pipes 3 corresponding to the top of the upper guide plate 4, middle guide plate 5, and lower guide plate 6 are respectively connected to the external material conveying structure. The equalizing pipes 3 on the top of the upper guide plate 4 and lower guide plate 6 are connected to the coating material conveying assembly, allowing the coating material to flow through the equalizing pipes 3 to the upper guide plate 4 and lower guide plate 6. The middle guide plate 5 is connected to the external main material conveying assembly, allowing the main material to flow through the equalizing pipes 3 to the middle guide plate 5. During production, the coating material first flows to the lower guide plate 6, and then to each of the dividing plates. Between 9, the material flows downward along the space between each diverter plate 9 and along the slope. Therefore, under the action of the diverter plate 9, the coating material will flow downward at every point on the top surface of the lower guide plate 6. The flowing coating material gradually flows to the bottom position of the barrier block 10, that is, at one side of the flow plate 7. By setting the diverter plate 9, the possibility of coating material accumulation or insufficient coating material at one point when the coating material flows to the bottom of the barrier block 10 is greatly reduced. Thus, the coating material is present at every position between the bottom of the barrier block 10 and the lower guide plate 6.

[0021] like Figures 2 to 6As shown, specifically, a limiting groove 14 is formed in the barrier block 10, and a threaded rod 15 is rotatably connected to the mold body 1. The threaded rod 15 is threadedly connected to the pusher plate 8, and the pusher plate 8 is slidably connected in the limiting groove 14. A motor 16 is fixedly installed on the mold body 1, and the output shaft of the motor 16 is fixedly connected to the threaded rod 15. The threaded rod 15 extends to the outside of the mold body 1, and a gear 17 is fixedly connected to the threaded rod 15. A chain 18 is connected between the gears 17. Here, the output shaft of the motor 16 is connected to the lower guide plate. The top baffle block 10 contains threaded rods 15, and gears 17 are installed on each threaded rod 15. The gears 17 are connected by a chain 18. When the motor 16 drives the threaded rods 15 on the output shaft to rotate, the gears 17 and the chain 18 drive each threaded rod 15 to rotate. The operator starts the controller by turning on the switch, which in turn drives the threaded rods 15 to rotate, causing the pusher plate 8 to move in the limiting groove 14, that is, gradually moving between the baffle block 10 and the lower guide plate. The controller moves the motor 16 between the two sides and, according to a set time, controls the rotation of the motor 16. After rotating in the forward direction for a set time, it rotates in the reverse direction, causing the pusher plate 8 to move in the reverse direction within the limit groove 14. During this movement, the pusher plate 8 can push the coating material between the barrier block 10 and the lower guide plate 6, allowing the coating material that may have accumulated too much to be pushed to a less accumulated position, further making the coating material more evenly distributed between the barrier block 10 and the lower guide plate 6. A protective device is fixedly installed on the mold body 1. The cover 11 is equipped with an electric push rod 12, which is fixedly connected to the flow plate 7. The gap between the bottom of the flow plate 7 and the upper guide plate 4 is the drainage channel 13. At the same time, due to the presence of the drainage channel 13, the coating material between the barrier block 10 and the lower guide plate 6 will continue to flow along the lower guide plate 6 through the drainage channel 13. Since the coating material between the barrier block 10 and the lower guide plate 6 is in a uniform distribution state at this time, the coating material continues to flow in a uniform distribution state after passing through the drainage channel 13.

[0022] Simultaneously, during the aforementioned process, as the coating material continues to flow evenly on the lower guide plate 6 after passing through the discharge channel 13, the main material is input into the equalization pipe 3 at the top of the middle guide plate 5. This allows the main material to flow onto the middle guide plate 5 through the equalization pipe 3. Following the aforementioned process, the main material gradually flows out evenly through the discharge channel 13. After passing through the discharge channel 13, the main material falls evenly from the middle guide plate 5, thus landing evenly on the coating material on the lower guide plate 6. At this point, the main material is evenly distributed on the coating material. Relatively speaking, the coating material has completed the coating of the bottom surface of the main material. As the coating material continues to flow on the lower guide plate 6 and the main material continues to flow evenly downwards on the middle guide plate 5 onto the coating material, the coating material always forms a coating of the bottom surface of the main material. The combined coating material and main material flow together on the lower guide plate. The material continues to flow upwards, and then the coating material is delivered to the distribution pipe 3 at the top of the upper guide plate 4. Under the same process principle as above, the coating material will be evenly discharged downwards through the discharge channel 13, and then fall onto the top surface of the main material. At this time, the coating material on the upper surface of the main material and the coating material on the bottom surface of the main material together form a uniform coating effect on the middle main material, forming the final material. In the subsequent process, the final material is finally extruded by the extrusion molding component in the mold body 1, and extruded through the extrusion port 2 to form the final corrugated tile. The operator drives the electric push rod 12 in the protective cover 11 to pull the flow plate 7 upwards by controlling the switch, thereby adjusting the size of the discharge channel 13 so that the flow rate of the main material or the coating material is different, thereby adjusting the overall production efficiency of the corrugated tile.
