Description

Technical Field

[0001] This invention relates to the field of pultrusion molding technology, and more particularly to a pultrusion profile molding apparatus. Background Technology

[0002] Pultrusion molding of composite materials is a process that produces composite profiles by impregnating continuous fibers or fabrics with resin under the traction of a traction device and curing the resin by heating a molding die.

[0003] Among them, the composite material pultrusion system must use a special injection box. The mold core is inserted into the injection box to form a cavity inside the pultruded profile. Glue is injected into the inside of the injection box through the injection port to impregnate the fiber layer of the preform. Then, the molding is achieved by heating and curing.

[0004] In existing pultrusion processes, the die core position shifts with changes in the fiber layer, and the fiber layer also moves under tension, compromising the molding quality of the hollow cavity in the pultruded profile. Furthermore, existing injection boxes cannot accommodate pultruded profiles of different specifications and sizes, thus reducing production efficiency. Moreover, to ensure sufficient contact and wetting of the fiber layer with the adhesive, operators continuously inject adhesive into the injection box. Since the injection box is directly connected to the threading plate, the adhesive inside the box is exposed through the gaps in the threading plate. This means operators cannot control the amount of adhesive injected and can only judge the amount by the amount of overflow, resulting in significant adhesive waste and high production costs. Summary of the Invention

[0005] The purpose of this invention is to provide a pultrusion profile forming apparatus that can reduce costs and increase efficiency while ensuring the quality of pultruded profile production.

The mold core can abut against the multiple limiting members and divide the injection channel into multiple fixed cavities.

[0008] The preform, along the first direction, is disposed at one end of the injection part and has a plurality of partition holes, the plurality of partition holes being connected one-to-one with a plurality of fixing cavities;

[0009] An anti-overflow mechanism includes a receiving component and an anti-overflow assembly. One end of the receiving component is connected to the end of the preform that is away from the glue injection component, and the other end is used to insert a fiber component. The interior of the receiving component is connected to the glue injection channel through the partition hole. The anti-overflow assembly is disposed on the receiving component and can control the amount of glue injected inside the receiving component.

[0010] A molded part is disposed at the other end of the injection part along the first direction, one end of the mold core is connected to the other end of the receiving part, and the other end of the mold core is sequentially inserted into the receiving part, the preform, the injection part and the molded part along the first direction.

[0011] Optionally, the injection component includes a first base plate, two first side plates, and a first top plate. The two ends of the first side plates are detachably connected to the first base plate and the first top plate, respectively. The two first side plates are parallel to each other and spaced apart, and together with the first base plate and the first top plate, they form the injection channel.

[0012] Optionally, the limiting member is detachably connected to the inner wall of the dispensing component and extends toward the interior of the dispensing channel.

[0013] Optionally, the receiving component includes an overflow cylinder and a through plate. The overflow cylinder is connected to the end of the preform away from the injection component and has an overflow groove that extends through the first direction.

[0016] Optionally, the pultrusion profile forming apparatus further includes a fixing plate and bolts, the fixing plate abutting against the other end of the receiving member, and the bolts passing through the fixing plate and screwed to the mold core.

[0017] Optionally, the anti-overflow assembly includes a lower sensor and an upper sensor. The receiving end of the lower sensor is disposed within the receiving member and is electrically connected to the dispensing machine, enabling the dispensing machine to dispense adhesive into the dispensing component. The receiving end of the upper sensor is disposed within the receiving member and is arranged sequentially from top to bottom at intervals with the receiving end of the lower sensor. The upper sensor is electrically connected to the dispensing machine and can control the dispensing machine to stop dispensing adhesive into the dispensing component.

[0018] Optionally, the molded part includes a second base plate, two second side plates and a second top plate. The two ends of the second side plates are detachably connected to the second base plate and the second top plate, respectively. The two second side plates are parallel to each other and spaced apart, and together with the second base plate and the second top plate, they form a receiving channel that runs through the first direction.

[0019] Optionally, along the first direction, the receiving component, the preform, the injection component, and the molded component are arranged coaxially in sequence.

The injection component has an injection channel extending along a first direction, allowing operators to directly inject adhesive into the channel using an injection machine, ensuring the fiber component is fully impregnated with the adhesive. Multiple limiting members are provided on the inner wall of the injection channel, with the die core abutting between them, effectively limiting the die core and preventing it from shifting and affecting the quality of the pultruded profile. The limiting members and the die core cooperate to divide the injection channel into multiple fixed cavities, allowing the fiber component to be stranded within each cavity. The constraint of the fixed cavities prevents the fiber component from shifting between the cavities and affecting the quality of the pultruded profile. Along the first direction, the preform is disposed at one end of the injection component and has multiple dividing holes, each corresponding to one of the fixed cavities. This allows the fiber component to first be divided into multiple strands through the dividing holes and then constrained by the fixed cavities, facilitating operation and improving work efficiency. The anti-overflow mechanism includes a receiving component and an anti-overflow assembly. One end of the receiving component is connected to the end of the preform facing away from the injection molding component, making the device layout more reasonable and compact. The other end of the receiving component is used to thread the fiber component, which is then sequentially threaded through the receiving component, the preform, and the injection molding component. The interior of the receiving component is connected to the injection channel through a partition hole, allowing the adhesive from the injection molding component to flow into the interior of the receiving component through the partition hole. The anti-overflow assembly is located on the receiving component and can control the amount of adhesive injected inside the receiving component, preventing the adhesive from overflowing during the pultrusion process, reducing adhesive waste, and saving costs. The molding component is located at the other end of the injection molding component along the first direction, and one end of the mold core is connected to the other end of the receiving component, further improving the stability of the mold core. The other end of the mold core is sequentially threaded through the receiving component, the preform, the injection molding component, and the molding component along the first direction to ensure the formation of the internal cavity of the pultruded profile and improve the quality of operation.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0035] like Figures 1-7 As shown, this embodiment provides a pultrusion profile forming apparatus, which includes an injection part 1, a preform 2, an anti-overflow mechanism 3, and a forming part 4. The injection part 1 has an injection channel 11 extending along a first direction. Multiple limiting members 12 are provided on the inner wall of the injection channel 11. The mold core 100 can abut against the multiple limiting members 12, dividing the injection channel 11 into multiple fixed cavities 111. Along the first direction, the preform 2 is disposed at one end of the injection part 1 and has multiple separating holes 21, which are correspondingly connected to the multiple fixed cavities 111. The anti-overflow mechanism 3 includes a receiving member 31 and an anti-overflow assembly 32. One of the receiving members 31... One end is connected to the preform 2 away from the injection part 1, and the other end is used to pass through the fiber part. The interior of the receiving part 31 is connected to the injection channel 11 through the partition hole 21. The anti-overflow component 32 is provided on the receiving part 31 and can control the amount of injection inside the receiving part 31. The molding part 4 is provided at the other end of the injection part 1 along the first direction. One end of the mold core 100 is connected to the other end of the receiving part 31. The other end of the mold core 100 is sequentially passed through the receiving part 31, the preform 2, the injection part 1 and the molding part 4 along the first direction.

[0036] In this embodiment, the injection part 1 has an injection channel 11 extending along a first direction. Operators can directly inject adhesive into the injection channel 11 using an injection machine to ensure the fiber part is fully impregnated with the adhesive. Multiple limiting members 12 are provided on the inner wall of the injection channel 11. The mold core 100 abuts against the multiple limiting members 12, thereby effectively limiting the mold core 100 and preventing it from shifting and affecting the quality of the pultruded profile. Through the cooperation of the limiting members 12 and the mold core 100, the injection channel 11 is divided into multiple fixed cavities 111, allowing the fiber part to be stranded and arranged in the multiple fixed cavities 111. The constraint effect of the fixed cavities 111 prevents the fiber part from shifting between the multiple fixed cavities 111 and affecting the quality of the pultruded profile. Along the first direction, the preform 2 is disposed at one end of the injection part 1 and has multiple dividing holes 21. These dividing holes 21 are connected one-to-one to multiple fixing cavities 111, allowing the fiber component to be first divided into multiple strands through the dividing holes 21 and then constrained by the fixing cavities 111, facilitating operation and improving work efficiency. The anti-overflow mechanism 3 includes a receiving component 31 and an anti-overflow assembly 32. One end of the receiving component 31 is connected to the end of the preform 2 opposite to the injection part 1, making the device layout more reasonable and compact. The other end of the receiving component 31 is used to thread the fiber component, allowing the fiber component to be sequentially threaded through the receiving component 31, the preform 2, and the injection part 1. The interior of the receiving component 31 is connected to the glue injection channel 11 through the partition hole 21, allowing the glue from the injection component 1 to flow into the interior of the receiving component 31 through the partition hole 21. An anti-overflow component 32 is disposed on the receiving component 31 to control the amount of glue injected into the receiving component 31, preventing the glue from overflowing during the pultrusion process, reducing glue waste, and saving costs. The molding component 4 is disposed at the other end of the injection component 1 along the first direction, and one end of the mold core 100 is connected to the other end of the receiving component 31, further improving the stability of the mold core 100. The other end of the mold core 100 is sequentially inserted into the receiving component 31, the preform 2, the injection component 1, and the molding component 4 along the first direction to ensure the formation of the internal cavity of the pultruded profile and improve the work quality. Through the above configuration, the pultrusion profile molding apparatus of this embodiment can reduce costs and increase efficiency, ensuring the work quality of the pultruded profile.

[0037] It should be noted that in this embodiment, the first direction is the direction of movement of the fiber component during the pultrusion process. In other embodiments, the first direction can be adjusted according to the actual pultrusion operation, and is not limited here. Furthermore, the fiber component can be made of glass fiber or polyester fiber, and is not limited here.

[0038] Specifically, such as Figures 1-6As shown, the glue injection component 1 includes a first base plate 13, two first side plates 14, and a first top plate 15. The two ends of the first side plates 14 are detachably connected to the first base plate 13 and the first top plate 15, respectively. The two first side plates 14 are parallel to each other and spaced apart, forming a glue injection channel 11 together with the first base plate 13 and the first top plate 15. This ensures the stability and reliability of the glue injection channel 11 and facilitates the placement of fiber components and the injection of glue. This design makes the assembly and disassembly of the components simple and quick, improving work efficiency. The detachable connection between the components can be achieved using bolts, clips, etc., and is not limited in detail here.

[0039] More specifically, such as Figure 6 As shown, in this embodiment, the first side plate 14 has a first recess at both its upper and lower ends, and the first bottom plate 13 and the first top plate 15 have a first protrusion that mates with the first recess, thereby facilitating the assembly and disassembly of the components by the operator. The first protrusion of the first top plate 15 has a plurality of connecting holes spaced apart along a first direction. Bolts are passed through the connecting holes and screwed to the first side plate 14 and the first bottom plate 13, thereby ensuring the structural integrity and stability of the injection molding component 1.

[0040] More specifically, in other embodiments, the first side plate 14 is provided with a first protrusion, and the first bottom plate 13 and the first top plate 15 are provided with a first recess that mates with the first protrusion, thereby facilitating the assembly of the injection molding part 1 by the operator. That is, the specific structure and position of the first protrusion and the first recess are not limited, as long as the above-mentioned functions can be achieved.

[0041] Specifically, such as Figure 5 As shown, in this embodiment, the preform 2 is a plate-like structure with an opening for the mold core 100 to pass through. Multiple separating holes 21 are spaced circumferentially along the opening. The opening helps maintain the stability of the mold core 100. The separating holes 21 allow the fiber components to be first separated into multiple strands, and then constrained by the fixing cavity 111, reducing fiber movement and improving work quality. In other embodiments, the preform 2 is a block-like structure; the specific structure of the preform 2 is not limited, as long as it achieves the above functions.

[0042] Specifically, such as Figures 1-6As shown, the limiting member 12 is detachably connected to the inner wall of the injection part 1, allowing operators to install, adjust, or replace the limiting member 12 as needed to accommodate mold cores 100 of different specifications and shapes, thus offering wider adaptability. Simultaneously, by adjusting the position and number of the limiting members 12, the requirements of different pultrusion profile operations can be met. The limiting member 12 extends inward toward the injection channel 11, ensuring a tight fit with the mold core 100 and guaranteeing accurate positioning of the mold core 100 within the injection channel 11. This helps reduce production errors caused by inaccurate positioning of the mold core 100, improving the quality of the pultruded profile. The limiting member 12 can be implemented using a limiting plate or a limiting block; no further limitations are specified here. The detachable connection between the limiting member 12 and the injection part 1 can be achieved using methods such as screwing or snap-fitting; no further limitations are specified here.

[0043] Specifically, such as Figures 1-4 As shown, the receiving component 31 includes an overflow cylinder 311 and a through plate 312. The overflow cylinder 311 is connected to the end of the preform 2 opposite to the injection component 1, so that the injection component 1, the preform 2 and the overflow cylinder 311 are connected as an integral structure, which facilitates the flow of the adhesive in the integral structure, achieves full wetting of the fiber component and the adhesive, and ensures the quality of the operation. The overflow cylinder 311 is provided with an overflow groove 3111 that runs through the first direction. The overflow groove 3111 is connected to the partition hole 21, so that the adhesive in the injection channel 11 can flow through the partition hole 21 on the preform 2 into the overflow groove 3111, thereby facilitating the anti-overflow component 32 to detect the amount of adhesive injected inside the receiving component 31. The through plate 312 is provided at the end of the overflow cylinder 311 opposite to the preform 2 to prevent the adhesive from flowing out of the overflow groove 3111 and causing material waste. By setting the threading plate 312, it is possible to ensure that the colloid is contained in the overflow groove 3111 and facilitate the threading of the fiber parts.

[0044] More specifically, such as Figures 1-4 As shown, the threading plate 312 is provided with multiple threading holes 3121, which are arranged in a matrix at intervals. The threading holes 3121 are used to thread the fiber components, ensuring that the fiber components can be evenly distributed during the threading process. At the same time, it is also convenient for operators to thread the fiber components into the corresponding threading holes 3121 according to the specific specifications of the profile, thereby improving work efficiency.

[0045] More specifically, the pultrusion profile forming apparatus also includes an elastic element, which is sandwiched between the fiber and the wall of the through hole 3121. This arrangement allows for precise positioning and insertion of the fiber, ensuring its stability and consistency during the pultrusion process. The elastic element also provides adjustment and buffering, enabling the through hole 3121 to accommodate stranded fibers of varying thicknesses, reducing friction and wear between the fiber and the hole wall during tensile movement, and improving operational quality. The elastic element can be made of nitrile rubber or neoprene rubber, etc., without further limitation.

[0046] Specifically, such as Figures 1-4 As shown, the pultrusion profile forming apparatus also includes a fixing plate 5 and bolts 6. The die core 100 protrudes from the receiving member 31, the fixing plate 5 abuts against the other end of the receiving member 31, and the bolts 6 pass through the fixing plate 5 and are screwed to the die core 100. This prevents the die core 100 from shifting during operation, thus avoiding affecting the quality of the pultruded profile. The fixing and limiting effect of the injection part 1, the preform 2, and the receiving member 31 on the die core 100 further improves the stability of the die core 100 in this apparatus, ensuring the quality of the pultruded profile.

[0047] Specifically, such as Figures 1-3 As shown, in this embodiment, the anti-overflow component 32 includes a lower sensor 321 and an upper sensor 322. Both the lower sensor 321 and the upper sensor 322 are liquid level sensors. The receiving end of the lower sensor 321 is disposed in the accommodating member 31. When the colloid height in the overflow tank 3111 does not reach the first threshold (i.e., the colloid cannot meet the minimum liquid level required for the fiber to be fully wetted), and thus cannot meet the requirement for the fiber to be fully wetted, the lower sensor 321 is electrically connected to the dispensing machine, which can control the dispensing machine to dispense colloid into the dispensing member 1 to meet the dispensing conditions for the fiber. The receiving end of the upper sensor 322 is disposed in the accommodating member 31 and is arranged alternately from top to bottom with the receiving end of the lower sensor 321. That is, the receiving end of the upper sensor 322 and the receiving end of the lower sensor 321 have a fixed height difference to ensure that the colloid height is within the fixed height difference and can meet the requirement for the fiber to be fully wetted. When the colloid level in the overflow tank 3111 reaches the second threshold (i.e., the highest liquid level that causes colloid overflow), the upper sensor 322, electrically connected to the dispensing machine, can control the dispensing machine to stop dispensing colloid into the dispensing part 1. This prevents colloid from overflowing from the receiving part 31 and causing colloid waste, thus improving production efficiency. By setting dual liquid level sensors, the amount of colloid flowing from the dispensing part 1 into the receiving part 31 can be precisely controlled, ensuring that the fiber parts are fully impregnated while preventing colloid overflow. Moreover, by automating the dispensing and stopping operations of the dispensing machine, the need for manual intervention is reduced, further improving production efficiency.

[0048] More specifically, in other embodiments, the lower sensor 321 and the upper sensor 322 may also be capacitive sensors, pressure sensors, etc. That is, the specific structure of the lower sensor 321 and the upper sensor 322 is not limited, as long as they can achieve the above-mentioned functions.

[0049] It should be noted that the dispensing machine is a standard piece of equipment in this field, and those skilled in the art are familiar with its specific working principle, so it will not be described in detail here.

[0050] Specifically, such as Figures 1-7 As shown, the molded part 4 includes a second base plate 41, two second side plates 42, and a second top plate 43. The two ends of the second side plates 42 are detachably connected to the second base plate 41 and the second top plate 43, respectively, allowing the molded part 4 to be easily assembled and disassembled when needed, facilitating cleaning, maintenance, or component replacement. The two second side plates 42 are parallel to each other and spaced apart, forming a through-channel 44 along the first direction together with the second base plate 41 and the second top plate 43. This allows the mold core 100 to pass through the through-channel 44. After the fiber component has fully contacted the colloid and been pre-formed, it can be further cured and formed through the through-channel 44 to form the product. The detachable connection between the above components can be achieved using bolts, clips, etc., without further limitation.

[0051] Specifically, along the first direction, the receiving part 31, the preform 2, the injection part 1 and the molding part 4 are arranged coaxially in sequence, ensuring that the entire process of the fiber part from insertion to molding is carried out on the same straight line, reducing the complexity and error of material transfer.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
