Description

Technical Field

[0001] This invention relates to the technical field of profile extrusion, and more particularly to an extrusion molding equipment for electric sliding door profiles and an electric sliding door. Background Technology

[0002] Profile extrusion molding equipment is a specialized machine that uses an extrusion machine to apply pressure to metal blanks and force them through a die to form profiles with specific cross-sectional shapes.

[0003] However, in existing technologies, molds are prone to damage during long-term use due to high temperatures, high pressures, and continuous friction from materials, requiring periodic replacement. Furthermore, producing profiles of different specifications and shapes necessitates changing to suitable molds. Currently, mold replacement mainly relies on two methods: manual labor and manual crane operation. In manual replacement, workers need to secure bolts to the mold's outer shell, then use wrenches, pry bars, and other tools to tighten the bolts. Manual disassembly involves pulling and prying the mold upwards. However, molds fresh from production are extremely hot, and workers, despite wearing only heat-resistant clothing, still face the risk of burns. Moreover, the disassembled molds are generally heavy, and since they are installed at a high position, workers often quickly drag them from a height to the ground. Although an outer shell is installed, it is highly susceptible to surface dents and deformation due to impacts caused by high temperatures. Similarly, installing a new mold requires workers to operate in a high-temperature environment. Manually adjusting the position based on experience is not only difficult to guarantee accuracy, but also inefficient due to high temperatures, significantly extending equipment downtime. When using a crane for replacement, after manually securing the bolts to the mold, the hook must be connected to the mold's lifting point. During lifting, manual guidance of the moving mold is required at all times. If the operator makes a mistake or the crane experiences brake failure or wire rope breakage, the mold is likely to fall. Furthermore, crane operations require ample space to ensure lifting safety, necessitating substantial reserving area. This not only limits the rational layout of other equipment in the workshop and reduces space utilization, but also hinders the flexibility of workshop planning. In limited workshop space, the crane is prone to collisions with surrounding equipment and facilities during mold lifting, further increasing the risk of equipment damage and the difficulty of replacement operations. In addition, the purchase, maintenance, and replacement of parts for the crane, as well as the professional training of operators, all require significant financial investment, and the cost of repairing malfunctions is even higher. Summary of the Invention

[0004] The purpose of this invention is to provide an extrusion molding equipment for electric sliding door profiles and an electric sliding door, solving the problem that existing equipment cannot effectively and quickly change profile molds.

[0005] This invention proposes an extrusion molding device for electric sliding door profiles, used to manufacture profile rods. The device includes a forming unit, a telescopic mold frame mounted on the forming unit, a mold placed inside the telescopic mold frame, a base frame fixedly connected to one side of the forming unit, a connecting frame slidably connected inside the base frame, a double-stage hydraulic cylinder and a locking frame fixedly connected to one side of the forming unit, a mold-changing component slidably connected to the locking frame, two receiving frames respectively fixedly connected to both ends of the connecting frame, a return spring connected between the locking frame and the mold-changing component, and an inclined block fixedly connected to the second output end of the double-stage hydraulic cylinder. The two receiving frames are symmetrical about the central axis of the connecting frame, and the sides of both receiving frames near the base frame are in contact with the base frame. The middle part of the connecting frame is connected to the first output end of the double-stage hydraulic cylinder. When the double-stage hydraulic cylinder retracts, the inclined block is located below the mold-changing component. When the double-stage hydraulic cylinder extends, it drives the two receiving frames upwards and drives the inclined block to change the mold through the mold-changing component.

[0006] Furthermore, the telescopic mold frame includes a telescopic rod fixedly connected to the forming device, and a mold base fixedly connected to the output end of the telescopic rod. Both the receiving frame and the mold base have U-shaped openings inside, and the side of the two receiving frames away from the base frame is a closed surface.

[0007] Furthermore, a through groove is provided on the side of the receiving frame away from the base frame, and when the first output end of the dual-stage hydraulic cylinder is fully extended, the U-shaped openings of the receiving frame and the mold base coincide.

[0008] Furthermore, the locking frame includes a frame body fixedly connected to the molding machine, two horizontal double rods and a vertical double rod fixedly connected to the frame body, a vertical plate slidably connected to the outside of the vertical double rods, and a weak spring connected between the vertical plate and the frame body. The mold changing component is slidably connected to the outside of the horizontal double rods.

[0009] Furthermore, the top of the vertical plate is curved on the side near the mold changing component, and a bottom block is provided at the bottom of the vertical plate, which is located below the receiving frame.

[0010] Furthermore, the mold changing component includes a horizontal bar slidably connected to the outside of the horizontal double bars, multiple vertical discs equidistantly arranged and fixedly connected to the outside of the horizontal bar, a connecting rod fixedly connected to the horizontal bar, and a rotating wheel rotatably connected to the other end of the connecting rod. The rotating wheel and the inclined block are located on the same plane, the top of the inclined block is an inclined surface, and the horizontal length of the inclined surface is equal to the length of the mold.

[0011] Furthermore, the number of vertical discs is at least three, and each of the vertical discs has a through hole at its top. The horizontal double rods are located inside the through holes, the bottom of the vertical discs has the same shape as the through groove, and the distance between two vertical discs is equal to the length of the mold.

[0012] Furthermore, a protrusion is provided on the leftmost vertical plate near the vertical plate, the bottom of the protrusion has a horizontal groove, the bottom end of the protrusion near the vertical plate is arc-shaped, and the protrusion is located above the receiving frame.

[0013] Furthermore, the forming device is provided with an extrusion component and an extrusion pad, the extrusion pad not being in contact with the frame.

[0014] Another aspect of the present invention provides: an electric sliding door, including profile rods manufactured using an extrusion molding device for electric sliding door profiles, and further including a glass door and an electric frame, wherein multiple profile rods are provided, the multiple profile rods are fixedly connected to form a rectangle, the glass door is fixedly connected inside the multiple profile rods, and both the glass door and the profile rods are located inside the electric frame.

[0015] The beneficial effects of this invention are:

[0016] 1. Driven by a two-stage hydraulic cylinder, the receiving frame can be moved upward quickly, enabling the coordinated operation of the inclined block and the mold changing parts to quickly and stably complete the mold ejection and installation, realizing automated mold replacement. It eliminates the need for direct contact with the high-temperature mold, effectively avoiding the risk of burns, shortening the mold replacement time, ensuring the accuracy of the new mold installation position, reducing equipment downtime, improving space utilization, and enhancing the flexibility of workshop planning.

[0017] 2. The mold is smoothly slid along the horizontal path formed by the U-shaped opening by the push of the inclined block. The base frame and the receiving frame work together to ensure that the mold will not deviate or shake during the movement. The old mold can be accurately pushed out to the recycling area and the new mold can be accurately installed in place. At the same time, the mold can be placed and taken out when the receiving frame is located at the bottom. Its open structure and adaptable U-shaped opening design provide great convenience for placing and taking out the mold. The operator does not need to carry the mold to a high place. The mold can be easily placed into the receiving frame at a low position. This reduces the labor intensity of the operator, shortens the mold preparation time, and avoids mold damage.

[0018] 3. By controlling the extension and retraction of the dual-stage hydraulic cylinder, the U-shaped opening of the receiving frame and the mold base can be precisely aligned. At the same time, the mold pushing and pulling actions are accurately completed by the mold changing parts. There is no need for manual operation of different parts to coordinate, which avoids problems such as improper mold installation and excessive replacement time caused by human operation errors. This enhances the stability and reliability of equipment operation, makes the action connection between various parts smoother and more stable, reduces the probability of equipment failure, extends the service life of equipment, and reduces the maintenance costs of enterprise equipment.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Example 1, refer to Figures 1-9This invention provides a first embodiment of an extrusion molding apparatus for electric sliding door profiles and an electric sliding door for manufacturing profile rods 12. The apparatus includes a forming device 1, a telescopic mold frame 2 mounted on the forming device 1, a mold 3 placed inside the telescopic mold frame 2, a base frame 4 fixedly connected to one side of the forming device 1, a connecting frame 5 slidably connected inside the base frame 4, a double-stage hydraulic cylinder 6 and a locking frame 7 fixedly connected to one side of the forming device 1, a mold changing component 8 slidably connected to the locking frame 7, and two receiving frames 9 respectively fixedly connected to both ends of the connecting frame 5. The return spring 10 between the locking frame 7 and the mold changing component 8, and the inclined block 11 fixedly connected to the second output end of the double-stage cylinder 6, the two receiving frames 9 are symmetrical about the central axis of the connecting frame 5, the side of the two receiving frames 9 near the base frame 4 is in contact with the base frame 4, the middle part of the connecting frame 5 is connected to the first output end of the double-stage cylinder 6, when the double-stage cylinder 6 retracts, the inclined block 11 is located below the mold changing component 8, when the double-stage cylinder 6 extends, it drives the two receiving frames 9 to move upward, and drives the inclined block 11 to change the mold 3 through the mold changing component 8, wherein the two receiving frames 9 are divided into left and right receiving frames 9.

[0032] Specifically, the base frame 4 provides stable support, the connecting frame 5 adopts a welded structure, and the main frame is made of high-strength alloy structural steel, filled with high-strength shock-absorbing material, which can effectively reduce vibration during equipment operation and improve equipment stability. Simultaneously, its surface undergoes special anti-rust treatment. Driven by the double-stage hydraulic cylinder 6, the connecting frame 5 can smoothly and quickly rise and fall, driving the receiving frames 9 at both ends to lift and lower the mold 3. The double-stage hydraulic cylinder 6 consists of two-stage piston rods, which extend and retract in a first- and second-stage sequence after being pushed by hydraulic oil. Combined with a hydraulic control valve, accurate control of extension and retraction is achieved. The locking frame 7 provides a stable sliding track and positioning reference for the mold changing component 8, and can also limit the movement of the mold changing component 8. The mold can slide smoothly along the locking frame 7 to push out the old mold 3 and accurately install the new mold 3. When the equipment is running, the operator only needs to issue a mold changing command on the control cabinet. The control system on the molding machine 1 will follow the preset program. First, it controls the telescopic mold frame 2 to slowly move out of the mold 3. Then, the first piston rod of the double-stage cylinder 6 extends, driving the connecting frame 5 to rise, so that the two receiving frames 9 can smoothly lift the mold 3. Next, the second piston rod of the double-stage cylinder 6 extends, pushing the inclined block 11 to rise. After the inclined block 11 contacts the inclined surface of the mold changing part 8, it uses the inclined surface transmission principle to push the mold changing part 8 to slide on the locking frame 7, pushing out the old mold 3 and placing it in the designated recycling position. At the same time, the pre-prepared new mold 3 is accurately pushed into the installation position in the telescopic mold frame 2.

[0033] Reference Figures 1-4The telescopic mold frame 2 includes a telescopic rod 21 fixedly connected to the molding machine 1, and a mold base 22 fixedly connected to the output end of the telescopic rod 21. Both the receiving frame 9 and the mold base 22 have U-shaped openings inside, and the side of the two receiving frames 9 away from the base frame 4 is a closed surface.

[0034] It is understandable that the outer shell of mold 3 is a supplementary structure to ensure that the size of mold 3 is the same as that of the U-shaped opening.

[0035] Specifically, the mold base 22, as the component that supports the mold 3, is a solid structure. Both the receiving frame 9 and the telescopic rod 21 have U-shaped openings inside, and the mold 3 can be placed inside the U-shaped openings. The U-shaped openings enable the mold 3 to be quickly positioned and accurately installed. The sides of the two receiving frames 9 that are close to the base frame 4 are in contact with the base frame 4, while the sides of the two receiving frames 9 that are away from the base frame 4 are closed surfaces. These closed surfaces are made of thickened steel plates. On the one hand, this prevents the mold 3 from slipping off the top of the receiving frame 9 during the transfer process, improving the safety of the mold changing process. On the other hand, the closed surfaces and the U-shaped openings cooperate to form a relatively closed space, fixing the position of the mold 3 inside the receiving frame 9, so that it will not shift before being moved.

[0036] Reference Figures 2-6 The receiving frame 9 has a through groove 91 on the side away from the base frame 4. The mold changing component 8 can pass through the through groove 91, thereby pulling the mold 3 inside the receiving frame 9. In addition, when the first output end of the double-stage cylinder 6 is fully extended, the U-shaped openings of the receiving frame 9 and the mold base 22 coincide, thereby forming a transverse channel to ensure the smoothness of the mold changing process, provide a stable guide path for the transverse movement of the mold 3, ensure that the old mold 3 is smoothly pushed out and the new mold 3 is accurately installed in place, and complete the quick change.

[0037] Reference Figures 2-6 The locking frame 7 includes a frame body 71 fixedly connected to the molding machine 1, two horizontal double rods 72 and a vertical double rod 73 fixedly connected to the frame body 71, a vertical plate 74 slidably connected to the outside of the vertical double rod 73, and a weak spring 75 connected between the vertical plate 74 and the frame body 71. The mold changing component 8 is slidably connected to the outside of the horizontal double rods 72.

[0038] Specifically, the surfaces of the two horizontal double rods 72 and the vertical double rods 73 are all polished to provide a smooth and stable sliding track for the mold changing part 8 and the vertical plate 74, preventing them from shifting or shaking during movement, thereby ensuring the accuracy of the mold 3 when moving laterally. When the vertical plate 74 is squeezed, it will slide along the vertical double rods 73, thereby compressing the weak spring 75.

[0039] Reference Figures 2-6The top of the vertical plate 74 is curved on the side near the mold changing part 8, so that the mold changing part 8 can squeeze the curved part, thereby causing the vertical plate 74 to move. The bottom of the vertical plate 74 is provided with a bottom block 741, which is located below the receiving frame 9. When the first stage rod of the double-stage cylinder 6 is fully retracted, the bottom of the receiving frame 9 will fit with the bottom block 741. At this time, the bottom block 741 is squeezed by the receiving frame 9, causing the vertical plate 74 to move down and compressing the weak spring 75.

[0040] During the mold changing process, when the second-stage rod of the double-stage hydraulic cylinder 6 extends, it drives the inclined block 11 to rise. The inclined block 11 pushes the mold changing component 8 to move horizontally along the double rod 72, thereby realizing the ejection of the old mold 3 and the pulling in of the new mold 3. At the same time, the mold changing component 8 is locked by the vertical plate 74.

[0041] Reference Figures 2-7 The mold changing component 8 includes a horizontal bar 81 slidably connected to the outside of the horizontal double bar 72, multiple vertical plates 82 equidistantly arranged and fixedly connected to the outside of the horizontal bar 81, a connecting rod 83 fixedly connected to the horizontal bar 81, and a rotating wheel 84 rotatably connected to the other end of the connecting rod 83. The rotating wheel 84 and the inclined block 11 are located on the same plane. The top of the inclined block 11 is an inclined surface, and the horizontal length of the inclined surface is equal to the length of the mold 3.

[0042] Specifically, multiple vertical discs 82 are equidistantly fixed to the outside of the horizontal bar 81. All are solid structures to ensure sufficient rigidity and thrust, thus forming multiple claw-like structures. When the new mold 3 moves upward with the receiving frame 9, the new mold 3 will enter between two vertical discs 82, while the old mold 3 moves horizontally with the mold base 22 and enters between the corresponding two vertical discs 82. The vertical discs 82 can firmly hold the two sides of the mold 3, ensuring that the mold 3 is stable and does not fall off during the mold changing process. The connecting rod 83 extending from the horizontal bar 81 is firmly connected to the horizontal bar 81 at one end and rotatedly connected to the rotating wheel 84 at the other end. When the double-stage cylinder 6 pushes the inclined block 11 upward, the rotating wheel 84 rolls along the inclined surface of the inclined block 11 and is compressed. During this process, the horizontal bar 81 drives the vertical discs 82 and the clamped mold 3 to slide laterally along the horizontal double bar 72, accurately realizing the action of pushing out the old mold 3 and pulling in the new mold 3. At the same time, the horizontal bar 81 compresses the return spring 10 when it moves.

[0043] Reference Figures 1-8 There are at least three vertical plates 82, and each vertical plate 82 has a through hole 801 at its top. The horizontal double rods 72 are located inside the through holes 801. The bottom of the vertical plate 82 is the same shape as the through groove 91, so that the vertical plate 82 can pass through the through groove 91 during the mold 3 replacement process. The distance between two vertical plates 82 is equal to the length of the mold 3, ensuring that the vertical plate 82 can accurately position and clamp the mold 3, and maintain the stability of the mold 3 during the mold replacement process. The forming device 1 is provided with an extrusion part 101 and an extrusion pad 102. The extrusion pad 102 does not contact the frame 71, thereby avoiding collision.

[0044] Specifically, there are at least three vertical plates 82, which can form two areas, so that the new and old molds 3 are located in the corresponding areas respectively. This multi-support layout can provide a more stable clamping force for the molds 3.

[0045] Reference Figures 1-9 On the leftmost vertical plate 82, a protrusion 802 is provided on the side near the vertical plate 74. A horizontal groove 803 is provided at the bottom of the protrusion 802. The bottom end of the protrusion 802 near the vertical plate 74 is arc-shaped, so that the displacement and cooperation between the two by squeezing are smoother and more fluid. The protrusion 802 is located above the receiving frame 9 to avoid the two from contacting and colliding.

[0046] Specifically, the horizontal groove 803 at the bottom of the protrusion 802 is adapted to the structure at the top of the vertical plate 74. Under the pressure of the protrusion 802, the vertical plate 74 moves downwards along the vertical double rod 73. Then, when the protrusion 802 no longer applies pressure to the vertical plate 74, the vertical plate 74 is pulled back by the weak spring 75, causing the top of the vertical plate 74 to embed into the horizontal groove 803. The vertical plate 74 is then locked together with the mold replacement component 8. At this point, the telescopic rod 21 can be used to pull the mold base 22, allowing the new mold 3 inside the mold base 22 to move back, while the old mold 3 remains stationary. Inside the left receiving frame 9, the double-stage hydraulic cylinder 6 retracts and moves downward, and the inclined block 11 moves downward simultaneously, no longer squeezing the rotating wheel 84. However, since the protrusion 802 is locked by the vertical plate 74, the vertical plate 74 cannot move as a whole. When the left receiving frame 9 drives the old mold 3 to move downward, the bottom of the receiving frame 9 will squeeze the bottom block 741, causing the vertical plate 74 to move downward. At this time, the mold changing part 8 will be completely unrestricted and will be pushed by the return spring 10 to move back along the path of the horizontal double rod 72. At this time, the old mold 3 is in a lower position and easy to pick up, thus realizing the smooth replacement of the old and new molds 3.

[0047] The working principle of this invention is as follows: When changing molds, the new mold 3 is placed on the right receiving frame 9. First, the telescopic rod 21 is controlled to extend, which stably pushes the mold base 22 and the mold 3 supported on it out of the molding machine 1. At this time, the mold base 22 and the old mold 3 inside it will horizontally enter between the two vertical plates 82. Subsequently, after the telescopic rod 21 is fully extended, the double-stage hydraulic cylinder 6 is controlled. The first-stage piston rod extends first, and the connecting frame 5 begins to rise steadily inside the base frame 4. The receiving frames 9, which are symmetrically fixed at both ends of the connecting frame 5, also rise synchronously. When the first-stage piston rod is fully extended, the receiving frame 9 rises to a specific position. At this time, the U-shaped opening inside the receiving frame 9 coincides with the U-shaped opening inside the mold base 22, forming a continuous and stable channel. In this structure, the new mold 3 inside the right receiving frame 9 will enter vertically between the two vertical discs 82. The second-stage piston rod of the double-stage cylinder 6 extends synchronously, pushing the inclined block 11 fixed at its second output end to rise. As the inclined block 11 rises, the inclined surface contacts the rotating wheel 84 and generates force. The rotating wheel 84 begins to roll under the push of the inclined surface of the inclined block 11. Since the rotating wheel 84 is connected to the horizontal bar 81 through the connecting rod 83, the rotating wheel 84 will drive the horizontal bar 81 to slide horizontally on the horizontal double rod 72, while compressing the return spring 10. Since the multiple vertical discs 82 fixed at equal intervals outside the horizontal bar 81 will jam the sides of the new and old molds 3, during the sliding process of the horizontal bar 81, the vertical discs 82 will push the old mold 3 out of the mold base 22 and along the receiving frame 9 and the mold base 22U. The channel formed by the shaped opening places the old mold 3 into the left receiving frame 9. Simultaneously, the new mold 3, pre-placed in the receiving frame 9, is pulled into the mold base 22. At the same time, as the horizontal bar 81 and vertical plate 82 move, the protrusion 802 on the leftmost side of the vertical plate 82 slides synchronously, applying pressure to the arc-shaped part of the vertical plate 74, pushing the vertical plate 74 downwards to compress the weak spring 75. As the protrusion 802 continues to move and no longer applies pressure to the vertical plate 74, the top of the vertical plate 74, under the partial rebound force of the weak spring 75, embeds into the horizontal groove 803 at the bottom of the protrusion 802 of the vertical plate 82, thereby locking the entire mold changing component 8. At this point, after the mold changing is completed, the extension... The retraction rod 21 pulls the mold base 22 and the new mold 3 inside it back. The double-stage cylinder 6 begins to retract, and the inclined block 11 moves down synchronously, no longer applying pressure to the rotating wheel 84. However, at this time, the mold changing part 8 is locked as a whole, while the receiving frame 9 descends with the retraction of the double-stage cylinder 6. When the left receiving frame 9 descends to the bottom, its bottom presses the bottom block 741 at the bottom of the vertical plate 74 again, causing the vertical plate 74 to move down along the vertical double rod 73. The top of the vertical plate 74 disengages from the transverse groove 803 of the protrusion 802 of the vertical plate 82, releasing the lock on the mold changing part 8. At this time, the mold changing part 8 moves back under the drive of the return spring 10. When the old mold 3 reaches the low position of the receiving frame 9, the operator takes it away.
