Description

Technical Field

[0001] This utility model belongs to the field of insertion equipment technology, and specifically relates to a device for automatically inserting a flexible strip into a mold cavity using a clamp. Background Technology

[0002] With the rapid development of my country's automobile industry, automobile production scale is increasing, and the demand for sealing strips, as an integral part of automobiles, is also growing. A complete sealing strip requires two production processes: cutting and injection molding, to form a finished product. To meet the demand for large-volume production, an automated production line integrating cutting and injection molding is being established to improve production efficiency. Because sealing strips are soft and need to be folded before insertion into the mold cavity, previously, operators manually folded the product and held it in the folded state before inserting it into the mold. However, the product's inherent softness and the inability of manual folding and shaping made insertion into the mold cavity difficult, time-consuming, and labor-intensive. Automated production lines utilize robots for product handling and automated strip insertion in the injection molding process to improve efficiency, making manual insertion by operators no longer suitable for current production needs. Utility Model Content

[0003] Purpose of the utility model: To overcome the above shortcomings, this utility model provides a device for automatically inserting a flexible strip into a mold cavity using a clamp. The flexible sealing strip clamp assembly uses a contoured cavity to hold the front end of the sealing strip in a folded state. The clamp contoured upper cover and clamp contoured base press and hold the sealing strip. Then, a transport chuck on a robot clamps a transport bracket on the clamp contoured base, transporting the flexible sealing strip clamp assembly to the insertion power module. The insertion power module pushes the flexible sealing strip on the clamp assembly, guided by the upper and lower contoured guides at the front end, into the mold cavity of the next mold. This achieves automated strip insertion to meet production needs, improving production efficiency and automation. When the product needs to be demolded after mold insertion, the robot can move the flexible sealing strip clamp assembly backward in the opposite direction, and the opening and closing components on the mold insertion power module can open the clamp contoured upper cover to allow the clamp to detach from the flexible sealing strip, providing a prerequisite for automated product demolding.

[0004] Technical solution: In order to achieve the above objectives, this utility model provides a device for automatically inserting a soft strip into a mold cavity using a clamp, comprising: a soft sealing strip clamp assembly, an insert power module, and a lower mold assembly. The soft sealing strip clamp assembly is detachably mounted on the insert power module, and the insert power module is located on the lower mold assembly.

[0005] The soft sealing strip clamp assembly includes a contoured upper guide, a contoured lower guide, a clamp contoured upper cover plate, and a clamp contoured base. The contoured upper guide, the contoured lower guide, the clamp contoured upper cover plate, and the clamp contoured base are connected by guide rods.

[0006] The insert power module includes a mounting plate, a lifting assembly, a lateral movement assembly, and an opening and closing assembly. The mounting plate is disposed on the lower mold assembly, the lifting assembly is slidably disposed on the mounting plate, the lateral movement assembly is disposed on the mounting plate and connected to the lifting assembly, and the opening and closing assembly is disposed on the mounting plate.

[0007] The lower mold assembly includes a lower mold and a lower mold cavity, wherein the lower mold cavity is disposed on the lower mold.

[0008] Furthermore, the fixture contouring top cover and the fixture contouring base are connected by a pivot shaft, and contouring cavities are provided between the contouring upper guide, the contouring lower guide, and between the fixture contouring top cover and the fixture contouring base; a limiting post is provided at the end of the guide rod. The pivot shaft connection between the fixture contouring top cover and the fixture contouring base allows the fixture contouring top cover to be opened.

[0009] Preferably, the base with a contoured shape is provided with a limiting clamp, and the upper cover plate of the contoured fixture is provided with a flip bar and a locking bar. The locking bar can cooperate with the limiting clamp to lock the upper cover plate of the contoured fixture and the base with a contoured fixture. The bottom surface of the base with a contoured fixture is trapezoidal and has guide parts on both sides. The bottom surface of the base with a contoured fixture is also provided with an insertion port.

[0010] Furthermore, the lifting assembly includes a lifting cylinder and a power jack. The power jack is located at the output end of the lifting cylinder and can be inserted into the bottom surface of the clamping base through an insertion port.

[0011] The lateral movement component includes a servo motor and an electric cylinder. The servo motor is connected to the electric cylinder, and the electric cylinder is mounted on a mounting plate with its output end connected to a lifting cylinder.

[0012] The mounting plate is provided with slots, and the lifting cylinder is slidably disposed in the slots. The surface of the mounting plate is provided with trapezoidal guide grooves, and L-shaped limiting blocks are also provided on both sides of the rear section of the mounting plate. The bottom surface of the clamping base can fit with the trapezoidal guide grooves, and the guide part of the clamping base can cooperate with the L-shaped limiting blocks. The trapezoidal guide grooves and L-shaped limiting blocks cooperate to restrict the movement direction of the clamping base on the mounting plate and prevent the position from shifting during movement.

[0013] The opening and closing assembly includes an opening and closing cylinder and an opening and closing top block. The opening and closing top block is located at the output end of the opening and closing cylinder. The opening and closing top block acts on the flip rod to open the clamp's contoured upper cover plate.

[0014] Preferably, the bottom surface of the mounting plate is provided with a linear slide rail, the lifting cylinder is connected to the linear slide rail via a slider, and reinforcing blocks are provided on both sides of the power lifting block, the reinforcing blocks being mounted on the lifting cylinder. The reinforcing blocks are located on both sides of the power lifting block to prevent it from shifting when driving the flexible sealing strip clamp assembly.

[0015] Furthermore, a limiting block is also provided on the lower mold, and the limiting block is located at the entrance of the lower mold cavity. The limiting block acts on the upper and lower contour guides, stopping their movement and aligning them with the lower mold cavity.

[0016] Furthermore, a transport port is provided on the side of the clamping base, and a transport bracket is installed on the transport port. The transport bracket is connected to the robot transport gripper.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0018] 1. This utility model provides a device for automatically inserting a soft strip into a mold cavity using a clamp. The front end of the sealing strip is held in a folded state by the contour cavity set in the soft sealing strip clamp assembly. The upper cover plate and the lower base of the clamp press and hold the sealing strip. Then, the soft sealing strip clamp assembly is transported to the insertion power module by the transport chuck on the robot clamping the transport bracket set on the clamp contour base. The insertion power module pushes the soft sealing strip on the soft sealing strip clamp assembly to be inserted into the next mold cavity under the guidance of the upper and lower contour guides at the front end, thereby realizing automated strip insertion to meet production needs, improve production efficiency and increase the degree of automation.

[0019] 2. This utility model is equipped with an opening and closing component. When the product needs to be demolded after the mold is joined, the robot can drive the soft sealing strip clamping component to move backward in the opposite direction. In conjunction with the opening and closing component on the mold insert power module, the clamping conformal cover plate is opened so that the clamp can be detached from the soft sealing strip. This prevents the product from breaking at the mold joint due to the clamping force of the soft sealing strip clamping component causing the soft sealing strip to move together, which would affect the yield. This provides a prerequisite for the automated demolding of the product. Attached Figure Description

[0036] like Figure 1-3 As shown, the lifting assembly 22 includes a lifting cylinder 221 and a power block 222. The power block 222 is located at the output end of the lifting cylinder 221 and can be inserted into the bottom of the clamp contour base 14 through the insertion port.

[0037] The transverse component 23 includes a servo motor and an electric cylinder. The servo motor is connected to the electric cylinder. The electric cylinder is mounted on the mounting plate 21 and its output end is connected to the lifting cylinder 221.

[0038] The mounting plate 21 is provided with a slot, the lifting cylinder 221 is slidably disposed in the slot, the surface of the mounting plate 21 is provided with a trapezoidal guide groove 211, and L-shaped limiting blocks 212 are also provided on both sides of the rear section of the mounting plate 21. The bottom surface of the clamping base 14 can fit with the trapezoidal guide groove 211, and the guide part of the clamping base 14 can cooperate with the L-shaped limiting block 212.

[0039] The opening and closing assembly 24 includes an opening and closing cylinder 241 and an opening and closing top block 242. The opening and closing top block 242 is located at the output end of the opening and closing cylinder 241. The opening and closing top block 242 acts on the flip rod 131 to open the clamp contour cover plate 13.

[0040] Preferred solutions, such as Figure 4 , Figure 5 The mounting plate 21 has a linear slide rail 213 on its bottom surface. The lifting cylinder 221 is connected to the linear slide rail 213 via a slider 2211. The power jack 222 has reinforcing blocks 2221 on both sides, and the reinforcing blocks 2221 are mounted on the lifting cylinder 221.

[0041] like Figure 2 As shown, a limiting top block 311 is also provided on the lower mold 31, and the limiting top block is located at the entrance of the lower mold cavity 32.

[0042] like Figure 6 As shown, a transport port 142 is provided on the side of the clamping base 14, and a transport bracket is installed on the transport port 142. The transport bracket is connected to the robot transport chuck.

[0043] The working principle of the clamp-driven flexible strip automatic insertion device for mold cavity disclosed in this utility model is as follows:

[0044] First, pull the lower guide 12 and the upper guide 11 forward until the tail of the guide rod 15 stops against the clamping base 14 and the clamping cover plate 13. Then, place the soft sealing strip on the clamping base 14 and the lower guide 12, with the front end of the soft sealing strip flush with the lower guide 12. Finally, close the clamping cover plate 13. The locking rod 132 on the clamping cover plate 13 locks with the limiting clamp 141 on the clamping base 14. The lower guide 12 and the upper guide 11 maintain the soft sealing strip in a folded state through the contouring cavity. The clamping base 14 and the clamping cover plate 13 press and clamp the soft sealing strip through the contouring cavity.

[0045] The lifting cylinder 241 on the insert power module 2 drives the power top block 242 to rise. The robot then transports the soft sealing strip insert clamp 1 with the sealing strip installed to the insert power module 2 installed on the lower mold 3 and fits it into the trapezoidal guide groove 211 and the power top block 242.

[0046] The servo motor drives the electric cylinder to extend, and at the same time the electric cylinder drives the lifting cylinder 221 to move forward on the linear guide rail 213. During the forward movement, the lifting cylinder 221 drives the rising power block 222 to press against the soft sealing strip insert clamp assembly 1 that is fitted with it and move forward together. During the forward movement, when it enters the L-shaped limit block 212, the L-shaped limit block 212 limits and presses against the clamp contour base 14 from top to bottom. In conjunction with the trapezoidal guide groove 212, the soft sealing strip insert clamp assembly 1 is restricted to move within the trapezoidal guide groove 212 to prevent positional deviation during the movement.

[0047] When the lower contour guide 12 and the upper contour guide 11 at the front end of the soft sealing strip insert clamping assembly 1 touch the limiting top block 311 in front of the lower mold cavity 32, the lower contour guide 12 and the upper contour guide 11 stop moving. At this time, the contour cavity formed by the combination of the lower contour guide 12 and the upper contour guide 11 docks with the lower mold cavity 32. Then, under the continued forward drive of the insert power module 2, the clamping contour base 14 and the clamping contour cover plate 13 on the soft sealing strip insert clamping assembly 1 hold the soft sealing strip and continue to move forward. With the mutual cooperation of the lower contour guide 12 and the upper contour guide 11 and the guide of the lower mold cavity 32, the sealing strip is guided into the mold cavity and the mold connection process begins.

[0048] During the mold-joining process, the opening and closing cylinder 241 drives the opening and closing top block 242 to extend. At the same time, during the upward process of the opening and closing top block 242, it presses against the flip rod 131 and drives it to rise. After the flip rod 131 is lifted by force, it drives the clamping upper cover plate 13 to rotate around the rotating shaft 16 and drives the locking rod 132 on it to disengage from the limiting clamp 141. At this time, the mold-joining cavity opens, thereby preventing the product from breaking at the mold-joining point due to the clamping force of the mold-joining cavity causing the soft sealing strip to move together, which would affect the yield.

[0049] When the fixture contour cover 13 is opened, the servo motor drives the electric cylinder to retract and move it to the standby position. Then the robot drives the soft sealing strip insert fixture assembly to move backward in the trapezoidal guide groove 211 until it is disengaged from the soft sealing strip.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
