Description

Technical Field

[0001] This invention relates to the field of resin matrix molding equipment technology, specifically to a vertical resin matrix molding equipment with a movable slider controlling the cavity. Background Technology

[0002] Composite material components are lightweight, high-strength, and rigid, playing an important role in reducing the weight of the carriage, reducing noise and vibration, improving safety and comfort, and reducing maintenance. They have become ideal structural components for high-speed rail transit.

[0003] Currently, common production methods for resin-based fiber-reinforced composite materials include hand lay-up molding, RTM molding, and SMC compression molding. Hand lay-up molding is not only inefficient and difficult to control in terms of product quality, but also emits large amounts of harmful volatile organic compounds, failing to meet environmental protection requirements, and its application scope has gradually decreased. RTM molding is a closed-mold production method, which is environmentally friendly, and the molding die cost is low, making it suitable for small-to-medium batch, multi-variety production. It produces high-quality products and is considered one of the main composite material production methods for the future. However, battery boxes used in the rail vehicle industry are large-sized components. Due to the limitations of resin flow properties in RTM molding, complex resin injection systems are usually required, making it difficult to avoid defects such as bubbles and dry spots during resin filling. While SMC molding is also a closed-mold production method, it typically requires higher molding pressure, leading to high investment in molds and equipment, and is generally used for mass production.

[0004] Therefore, in order to meet the requirements of small-batch, multi-variety, and high-quality production of large-size composite material components for rail vehicles, it is urgent to design and develop new production methods. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical molding device and method for resin matrix with a movable slider controlling the cavity, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A vertical molding device for resin matrix with movable slider control cavity includes an upper mold and a lower mold. The lower mold is mounted on a lower mold base. A mold closing and locking mechanism is provided at the upper end of the lower mold base. An injection pipe joint is provided at the upper end of the upper mold. An injection pipe is connected to the injection pipe joint. The end of the injection pipe away from the injection pipe joint is connected to the mold closing and locking mechanism. A movable slider assembly is provided at the upper end of the lower mold base.

[0008] In a preferred embodiment, the upper mold is configured with an inverted U-shape, and the sidewalls of the upper mold are perpendicular to the ground, while the upper wall of the upper mold is parallel to the ground. Both the upper and lower molds have corrugated profiles on their upper walls, and the transitions of the corrugated profiles are chamfered to allow the resin matrix to fill the cavity under gravity during sidewall molding. The lower mold is used for molding the inner surface of the battery box. The corrugated profiles have chamfered transitions to reduce defects caused by the resin matrix flowing horizontally at the transition to vertical flow, thereby controlling product quality.

[0009] In a preferred embodiment, the movable slider assembly includes several aluminum sleeves, each of which has a mounting cavity at one end. A permanent magnet is fixedly installed inside each mounting cavity. A steel component is installed on one side of the permanent magnet, and an electromagnet is installed at the end of the steel component away from the permanent magnet. One end of each electromagnet is electrically connected to the molding controller via an external circuit. The movable slider assembly consists of sliders on the same plane forming a group. The number of movable slider groups is determined according to the external dimensions of the housing. The design is to drive the movable sliders to move horizontally, so that the resin matrix in the side wall area can be uniformly and evenly bonded to the fiber reinforcement when it flows downward under gravity.

[0010] In a preferred embodiment, a limiting slider is fixedly installed at the lower end of the aluminum sleeve, a limiting groove is formed on the upper side wall of the aluminum sleeve, a ball is installed at the bottom end of the limiting slider, a limiting protrusion is provided inside the limiting groove, a rack is provided on both the left and right sides of the bottom end of the limiting protrusion, a gear is meshed below the rack, a rotating shaft is provided through the middle of the two gears, one end of the rotating shaft passes through the side wall of the aluminum sleeve and is fixedly connected to a knob provided at the outer end of the aluminum sleeve. The limiting slider and the limiting groove facilitate the movement of the aluminum sleeve, making the movement smoother and reducing friction between the aluminum sleeves.

[0011] In a preferred embodiment, the limiting slider is a T-shaped slider, and the limiting slider matches the limiting groove. The limiting groove has a rectangular groove for the rack to move inside. The outer wall of the aluminum sleeve has an indicator scale at the knob, and the knob has an indicator arrow. The indicator scale and the indicator arrow facilitate the determination of the rack's position and enable precise adjustment of the limiting protrusion's position.

[0012] In a preferred embodiment, the upper end of the lower mold base is provided with a limiting groove that matches the limiting slider, and a groove is provided on one side of the lower mold base.

[0013] In a preferred embodiment, the mold clamping and locking mechanism includes a mounting cylinder fixedly disposed inside a groove. A movable plug is disposed inside the mounting cylinder. One end of the mounting cylinder has a feed inlet, and the other end has a discharge outlet. A support rod is fixedly disposed at one end of the movable plug. One end of the support rod passes through the side wall of the mounting cylinder, and an adjusting rod is threaded onto one end of the support rod. A locking plate is rotatably disposed at the end of the adjusting rod away from the support rod. A return spring is fixedly disposed at one end of the movable plug. When the resin base is added, it first passes through the mounting cylinder. The movable plug inside the mounting cylinder drives the support rod and the adjusting rod to move, thereby using the adjusting rod to drive the locking plate to press and fix the lower mold.

[0014] In a preferred embodiment, the feed inlet is connected to the storage tank via a feed pipe and a feed pump, the discharge outlet is connected via a filling pipe and a filling pipe connector, the inner side wall of the upper mold is provided with a nozzle, the outer side wall of the adjusting rod is provided with a scale line, the bottom end of the locking plate is fixedly provided with a limit block, and the lower mold base is provided with a sliding groove that matches the limit block. The limit block prevents the locking plate from rotating with the adjusting rod.

[0015] In a preferred embodiment, an electric heating wire is embedded in the inner wall of the mounting cylinder, and a through hole is provided at the end of the mounting cylinder. A sealing cover is provided at the through hole. The electric heating wire can heat and melt the cured resin base, thereby facilitating the export of the resin base from inside the mounting cylinder.

[0016] This invention also provides a method for using a vertical resin matrix molding device with a movable slider controlling the cavity, comprising the following steps:

[0017] S1, adjust the mold clamping and locking mechanism and the movable slider group according to the thickness of the product to be processed and the thickness of the resin-based fiber reinforced composite material. After the adjustment is completed, assemble the upper mold and the lower mold, and connect the external circuit that controls the movement of each movable slider group.

[0018] S2, based on the temperature and viscosity of the injected resin base, the current change and loading method of each group in the movable slider group are designed, and the molding controller is used to control each group to move horizontally from top to bottom in sequence at a reasonable speed. Molding starts from the top surface, and the array nozzles control the injection speed.

[0019] S3, the fiber reinforcement is laid on the inner surface of the upper mold, and then the resin base is pumped into the mounting cylinder by the material pump. The locking plate on one side of the mounting cylinder extends out to squeeze and lock the lower mold. The resin base flowing out of the mounting cylinder flows into the nozzle on the inner wall of the upper mold through the injection pipe for injection.

[0020] S4. When the resin matrix flows to the sidewall, the movable slider group is energized from top to bottom. After being energized, the movable slider group moves horizontally towards the central axis in sequence, providing successively open empty cavities for the resin matrix to flow, so as to overcome the effect of uneven flow rate caused by gravity, and make the resin matrix maintain a uniform flow rate and fill each part during sidewall molding.

[0021] S5. After the resin-based injection is completed and cured, open the sealing cover at the end of the mounting cylinder, use the electric heating wire to heat and melt the resin-based material inside the mounting cylinder, use the movable plug to push out the resin-based material, and stop the clamping and locking mechanism from squeezing and locking the lower mold. Remove the lower mold and take out the product.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The resin matrix vertical molding equipment with movable slider control cavity described in this invention achieves reasonable control of gravity through the motion control of the movable slider group for thin-walled shells with simple configurations. This allows the resin matrix to be filled relatively evenly downwards during sidewall molding, thereby controlling product quality and reducing the operational technical difficulty compared to traditional vacuum molding methods. The equipment is equipped with structures such as limit sliders, limit grooves, balls, gears, racks, limit protrusions, and indicator scales, which not only facilitate the movement of the movable slider group but also limit the position of the aluminum sleeve. The aluminum sleeve has a better effect on limiting the flow rate of the resin matrix, and the position of the limit protrusions can be adjusted to process fiber reinforcements of different thicknesses.

[0024] 2. The resin matrix vertical molding equipment with movable slider controlled cavity described in this invention has a mold closing and locking mechanism connected to the feeding end of the resin matrix. When the resin matrix is ​​fed, it passes through the mounting cylinder in the mold closing and locking mechanism, causing the movable plug inside the mounting cylinder to move. The movable plug can drive the locking plate to press the lower mold through the support rod and the adjusting rod, thereby closing the upper and lower molds. Moreover, the distance between the locking plate and the mounting cylinder can be adjusted, which is convenient for processing products of different thicknesses. The structure is simple and the operation is convenient. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-6 The present invention provides the following technical solution:

[0036] A vertical molding device for resin matrix with movable slider control cavity includes an upper mold 1 and a lower mold 2. The lower mold 2 is mounted on a lower mold base 3. A mold closing and locking mechanism 6 is provided at the upper end of the lower mold base 3. An injection pipe connector 4 is provided at the upper end of the upper mold 1. An injection pipe 5 is connected to the injection pipe connector 4. The end of the injection pipe 5 away from the injection pipe connector 4 is connected to the mold closing and locking mechanism 6. A movable slider assembly 7 is provided at the upper end of the lower mold base 3.

[0037] In a preferred embodiment, the upper mold 1 is configured with an inverted U-shape, and the sidewalls of the upper mold 1 are perpendicular to the ground, while the upper wall of the upper mold 1 is parallel to the ground. Both the upper mold 1 and the lower mold 2 have corrugated profiles 8 on their upper walls, and the transitions of the corrugated profiles 8 are chamfered to allow the resin matrix to fill the cavity under gravity during sidewall molding. The lower mold is used for molding the inner surface of the battery box. The corrugated profiles have chamfers at the transitions to reduce defects caused by the resin matrix flowing horizontally at the transitions to vertical flow, thereby controlling product quality.

[0038] In a preferred embodiment, the movable slider group 7 includes a plurality of aluminum sleeves 701. Each aluminum sleeve 701 has an installation cavity at one end. A permanent magnet 702 is fixedly installed inside each installation cavity. A steel part 703 is provided on one side of the permanent magnet 702. An electromagnet 704 is provided at the end of the steel part 703 away from the permanent magnet 702. One end of each electromagnet 704 is electrically connected to the molding controller 706 through an external circuit 705. When the electromagnet 704 is de-energized, the two electromagnets 704 in the same group repel each other and move away from each other, so that the side wall of the aluminum sleeve 701 compresses the fiber reinforcement 9 tightly against the inner side wall of the upper mold 1. When the electromagnet 704 is energized, the two electromagnets 704 in the same group attract each other, so that the side wall of the aluminum sleeve 701 moves away from the fiber reinforcement 9, thereby creating a gap between the aluminum sleeve 701 and the fiber reinforcement 9, allowing the resin matrix to flow into the gap and maintain a flowing state.

[0039] In a preferred embodiment, a limiting slider 707 is fixedly installed at the lower end of the aluminum sleeve 701, a limiting groove 708 is formed on the upper side wall of the aluminum sleeve 701, a ball bearing 709 is installed at the bottom end of the limiting slider 707, a limiting protrusion 710 is provided inside the limiting groove 708, and a rack 711 is provided on both the left and right sides of the bottom end of the limiting protrusion 710. A gear is meshed below the rack 711, and a rotating shaft 713 is passed through the middle of the two gears. One end of 13 passes through the side wall of aluminum sleeve 701 and is fixedly connected to the knob 714 located at the outer end of aluminum sleeve 701. The setting of limiting slider 707, limiting groove 708 and ball 709 facilitates the movement of aluminum sleeve 701 and reduces friction between aluminum sleeve 701 and other aluminum sleeves 701 when moving. The setting of limiting protrusion 710 can play a limiting role and control the gap between aluminum sleeve 701 and fiber reinforcement 9. The limiting protrusion 710 can be adjusted by gear and rack 711 to facilitate the processing of different products.

[0040] In a preferred embodiment, the limiting slider 707 is a T-shaped slider, and the limiting slider 707 matches the limiting groove 708. The limiting groove 708 is provided with a rectangular groove 712 for the rack 711 to move. The outer wall of the aluminum sleeve 701 is provided with an indicator scale 715 at the knob 714. The knob 714 is provided with an indicator arrow 716. The setting of the indicator scale 715 and the indicator arrow 716 facilitates the control of the adjustment distance of the limiting protrusion 710.

[0041] In a preferred embodiment, the upper end of the lower mold base 3 is provided with a limiting groove 708 that matches the limiting slider 707, and a groove is provided on one side of the lower mold base 3.

[0042] In a preferred embodiment, the mold clamping locking mechanism 6 includes a mounting cylinder 601 fixedly disposed inside a groove. A movable plug 602 is disposed inside the mounting cylinder 601. One end of the mounting cylinder 601 has a feed inlet 603, and the other end has a discharge outlet 604. A support rod 605 is fixedly disposed at one end of the movable plug 602. One end of the support rod 605 passes through the side wall of the mounting cylinder 601, and an adjusting rod 606 is threaded onto one end of the support rod 605. A locking plate 607 is rotatably disposed at the end of the adjusting rod 606 away from the support rod 605. A return spring 608 is fixedly disposed at one end of the movable plug 602. While most existing methods use hydraulic or pneumatic locking, this application utilizes the feeding of the resin matrix to achieve the operation of the mold clamping locking mechanism 6, eliminating the need for an additional drive source for locking, making it more convenient to use.

[0043] In a preferred embodiment, the feed inlet 603 is connected to the storage tank via a material pipe and a material pump, the discharge outlet 604 is connected via a filling pipe 5 and a filling pipe connector 4, the inner side wall of the upper mold 1 is provided with a nozzle, the outer side wall of the adjusting rod 606 is provided with a scale line 609, the bottom end of the locking plate 607 is fixedly provided with a limit block 610, and the lower mold base 3 is provided with a sliding groove that matches the limit block 610. The limit block 610 can restrict the locking plate 607 from rotating with the adjusting rod 606, so that when the adjusting rod 606 rotates, it can drive the locking plate 607 to move.

[0044] In a preferred embodiment, an electric heating wire 611 is embedded in the inner wall of the mounting cylinder 601, and a through hole is provided at the end of the mounting cylinder 601. A sealing cover plate 612 is provided at the through hole. The electric heating wire 611 can heat the resin matrix cured inside the mounting cylinder 601, making it convenient to push the resin matrix out of the mounting cylinder 601.

[0045] This invention also provides a method for using a vertical resin matrix molding device with a movable slider controlling the cavity, comprising the following steps:

[0046] S1, adjust the mold clamping and locking mechanism 6 and the movable slider group 7 according to the thickness of the product to be processed and the thickness of the resin-based fiber reinforced composite material. After the adjustment is completed, assemble the upper mold 1 and the lower mold 2, and connect the external circuit 705 that controls the movement of each movable slider group 7.

[0047] When the movable slider group 7 is adjusted, the knob 714 drives the rotating shaft 713 to rotate. When the rotating shaft 713 rotates, it drives the gear to rotate. When the gear rotates, it causes the rack 711 to drive the limiting protrusion 710 to move. The moving distance of the limiting protrusion 710 is determined according to the rotation angle of the knob 714.

[0048] When adjusting the mold clamping mechanism 6, rotate the adjusting rod 606. Since the adjusting rod 606 is threadedly connected to the support rod 605, when the adjusting rod 606 rotates, it can slide relative to the support rod 605, so that the adjusting rod 606 drives the locking plate 607 to move. The position of the adjusting rod 606 can be determined according to the scale line 609 on the adjusting rod 606.

[0049] S2, the current change magnitude and loading method of each group in the movable slider group 7 are designed according to the temperature and viscosity of the injected resin base, and the molding controller 706 is used to control each group to move horizontally from top to bottom in sequence at a reasonable speed. Molding starts from the top surface, and the array nozzle controls the injection speed.

[0050] S3, the fiber reinforcement 9 is laid on the inner surface of the upper mold 1, and then the resin base is pumped into the mounting cylinder 601 by the material pump. The locking plate 607 on one side of the mounting cylinder 601 extends out to squeeze and lock the lower mold 2. The resin base flowing out of the mounting cylinder 601 flows into the nozzle on the inner wall of the upper mold 1 through the injection pipe 5 for injection.

[0051] During the laying of fiber reinforcement 9, all electromagnets 704 are energized to facilitate the laying of fiber reinforcement 9. After laying is completed, all are de-energized. After the electromagnets 704 are de-energized, the electromagnets 704 in the same group repel each other, causing the aluminum sleeves 701 to move away from each other. The sidewall of the aluminum sleeve 701 is in close contact with the fiber reinforcement 9 without gaps, preventing the resin matrix from flowing downwards. When the resin matrix is ​​fed by the material pump, it flows through the installation cylinder 601 and into the inlet 603 at one end of the installation cylinder 601, so that... The resin matrix pushes the movable plug 602 to move. When the movable plug 602 moves, it can drive the locking plate 607 to move through the support rod 605 and the adjusting rod 606. Thus, the locking plate 607 is used to press the lower mold 2, realizing the locking of the upper mold 1 and the lower mold 2. After the locking plate 607 presses the lower mold 2, the movable plug 602 moves to one end of the discharge port 604, so that the resin matrix flows into the injection pipe 5 through the discharge port 604, and flows into the nozzle through the injection pipe joint 4 for resin matrix injection.

[0052] S4. When the resin matrix flows to the sidewall, the movable slider group 7 is energized from top to bottom. After being energized, the movable slider group 7 moves horizontally towards the central axis in sequence, providing successively open empty cavities for the resin matrix to flow, so as to overcome the effect of uneven flow rate caused by gravity, and make the resin matrix maintain a uniform flow rate and fill each part during sidewall molding.

[0053] As the injected resin matrix flows downward, the electromagnets 704 are energized sequentially from top to bottom. The energized electromagnets 704 attract each other, causing two electromagnets 704 in the same group to approach each other. The electromagnets 704 drive the aluminum sleeve 701 to move, leaving a certain gap between the aluminum sleeve 701 and the side wall of the fiber reinforcement 9. This allows the resin matrix to descend at a uniform speed along the gap. When the aluminum sleeve 701 moves, the ball 709 can move inside the limiting groove 708. When the electromagnets 704 drive the aluminum sleeve 701 to a certain extent, the limiting protrusion 710 can limit the ball 709, preventing the ball 709 from moving further, thereby controlling the gap between the aluminum sleeve 701 and the fiber reinforcement 9.

[0054] S5. After the resin-based injection is completed and cured, open the sealing cover plate 612 at the end of the mounting cylinder 601, use the electric heating wire 611 to heat and melt the resin-based inside the mounting cylinder 601, use the movable plug 602 to push out the resin-based, the mold clamping and locking mechanism 6 stops the compression and locking of the lower mold 2, remove the lower mold 2, and take out the product.

[0055] like Figure 7 As shown, the sidewall molding process can be divided into three zones: a curing zone A, an unfilled zone B, and an uninjected zone C. In the curing zone A, the resin matrix is ​​not completely cured, so that when the next set of movable sliders starts to move and create the cavity area, the resin matrix still maintains a certain fluidity. The unfilled zone B has already moved under program control, creating a cavity for the resin matrix in the curing zone to flow and fill. In the uninjected zone C, the movable slider is still tightly pressed against the fiber reinforcement. After all the resin matrix is ​​injected, it is cured. After curing, the remaining resin matrix inside the mounting cylinder 601 is heated and melted by the electric heating wire 611. Then, the sealing cover plate 612 is opened to push out the remaining resin matrix inside the mounting cylinder 601. The locking plate 607 loses its limiting function on the lower mold 2. The lower mold 2 can be disassembled and the product can be taken out.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The vertical molding equipment for resin matrix with movable slider controlled cavity according to claim 5, characterized in that: An electric heating wire (611) is embedded in the inner wall of the mounting cylinder (601), and a through hole is provided at the end of the mounting cylinder (601), and a sealing cover plate (612) is provided at the through hole.

7. A method of using a vertical molding apparatus for resin matrix with a movable slider-controlled cavity according to any one of claims 1-6, characterized in that, Includes the following steps: S1, adjust the mold clamping mechanism (6) and movable slider group (7) according to the thickness of the product to be processed and the thickness of the resin-based fiber reinforced composite material. After adjustment, assemble the upper mold (1) and lower mold (2) and connect the external circuit (705) to control the movement of each movable slider group (7). S2, based on the temperature and viscosity of the injected resin base, design the current change magnitude and loading method of each group in the movable slider group (7), and use the molding controller (706) to control each group to move horizontally from top to bottom in sequence at a reasonable speed. Molding starts from the upper surface, and the array nozzle controls the injection speed. S3, the fiber reinforcement (9) is laid on the inner surface of the upper mold (1), and then the resin base is pumped into the mounting cylinder (601) by the material pump. The locking plate (607) on one side of the mounting cylinder (601) extends out to squeeze and lock the lower mold (2). The resin base flowing out of the mounting cylinder (601) flows into the nozzle on the inner wall of the upper mold (1) through the injection pipe (5) for injection. S4, when the resin matrix flows to the sidewall, the movable slider group (7) is energized from top to bottom. After being energized, the movable slider group (7) moves horizontally towards the central axis in sequence, providing an empty cavity that opens sequentially for the resin matrix to flow, so as to overcome the effect of uneven flow rate caused by gravity, and make the resin matrix maintain a uniform flow rate and fill each part during sidewall molding. S5. After the resin-based injection is completed and cured, open the sealing cover plate (612) at the end of the mounting cylinder (601), use the electric heating wire (611) to heat and melt the resin-based inside the mounting cylinder (601), use the movable plug (602) to push out the resin-based, the mold clamping mechanism (6) stops the compression and locking of the lower mold (2), remove the lower mold (2), and take out the product.
