Description

Technical Field

[0001] This utility model relates to the field of automotive decorative mold technology, and in particular to a material guiding mechanism for an automotive decorative strip mold. Background Technology

[0002] Decorative strips are key protective components of car bodies, made of various materials such as chrome-plated metal and plastic. They are mainly used for paint protection and aesthetic enhancement of parts such as doors and roofs. Their design combines curved fitting technology with injection molding technology. When resisting scratches from sand and gravel and minor collisions, they can reduce damage to the car body through built-in energy-absorbing buffer strips. In the production process of automotive decorative strips, stamping dies are generally used to process the automotive decorative strips.

[0003] In the existing technology, the stamping dies used for processing automotive trim strips are generally equipped with guide plates. However, these guide plates are mostly fixedly installed on the stamping die. This arrangement makes it inconvenient to adjust the position of the guide plates. The adjustment process is cumbersome and complicated, wasting time and effort. At the same time, it is inconvenient to replace the buffer components on the guide plates, which affects the normal use of the die and reduces the processing efficiency of automotive trim strips. Utility Model Content

By threading the guide plates to the bidirectional lead screw, the bidirectional lead screw can rotate to drive the guide plates to move.

[0008] As a further description of the above technical solution: sliders are fixedly installed on the inner walls of both ends of the rubber buffer sleeve, and sliding grooves adapted to the sliders are opened on the side walls of both ends of the guide plate.

The side walls of the two guide plates 12 away from the slide rod 11 are threaded to the bidirectional lead screw 10 through the forward thread and the reverse thread, respectively. A rubber buffer sleeve 13 is fitted on the outer surface of the guide plate 12.

[0024] To replace the rubber buffer sleeve 13, sliders 14 are fixedly installed on the inner walls of both ends of the rubber buffer sleeve 13. Slide grooves adapted to sliders 14 are opened on the side walls of both ends of the guide plate 12. A locking block 15 is fixedly installed on the inner wall of the rubber buffer sleeve 13.

A fixing bolt 18 is threadedly connected to the side wall of the guide plate 12 away from the rubber buffer sleeve 13. The fixing bolt 18 passes through the side wall of the guide plate 12 and is inserted into the fixing block 17.

[0025] By setting up a base 1, mounting bracket 2, hydraulic rod 3, mounting plate 4, upper mold base 5, lower mold base 6, telescopic rod 7, groove 8, servo motor 9, bidirectional lead screw 10, slide rod 11, guide plate 12, rubber buffer sleeve 13, slider 14, locking block 15, locking groove 16, fixing block 17, and fixing bolt 18, the function of moving the position of the guide plate 12 is realized. This improves the installation method of the guide plate 12 in the prior art, making it quick and convenient to adjust the position of the guide plate 12, saving time and effort. At the same time, the rubber buffer sleeve 13 can be quickly and conveniently replaced, ensuring the normal use of the mold and improving the processing efficiency of automotive trim strips.

[0026] The upper surface of the lower mold base 6 is provided with a material discharge assembly, which includes a receiving groove 19. The receiving groove 19 is opened on the upper surface of the lower mold base 6. The inner wall of the receiving groove 19 is slidably connected to a material discharge block 20. Movable grooves 21 are opened on both sides of the inner wall of the receiving groove 19. Movable blocks 22 that are adapted to the movable grooves 21 are fixedly installed on both sides of the material discharge block 20. A positioning rod 23 is fixedly installed on the inner wall of the movable groove 21. The movable block 22 is sleeved on the outer surface of the positioning rod 23. A spring 24 is sleeved on the outer surface of the positioning rod 23. The top end of the spring 24 is fixedly connected to the movable block 22, and the bottom end of the spring 24 is fixedly connected to the bottom inner wall of the movable groove 21.

[0027] By setting up a receiving groove 19, a discharge block 20, a movable groove 21, a movable block 22, a positioning rod 23, and a spring 24, the function of quickly and conveniently discharging the processed automotive trim strip is realized. By using the discharge block 20, which can be raised and lowered and automatically returns to its original position, when the upper mold base 5 and the lower mold base 6 are closed, the discharge block 20 slides into the interior of the receiving groove 19. When the upper mold base 5 and the lower mold base 6 are separated, under the action of the spring 24, the discharge block 20 slides out of the receiving groove 19 and lifts up the automotive trim strip to complete the discharge, thus improving the practicality of the mold.

[0028] Working Principle: When processing the automotive trim strip using the mold, the trim strip is first placed on the upper surface of the lower mold base 6. Then, the servo motor 9 is started. When the servo motor 9 runs, it drives the bidirectional lead screw 10 to rotate inside the groove 8. During the rotation of the bidirectional lead screw 10, the two guide plates 12 are moved through the forward and reverse threads. Under the action of the slide rod 11, the two guide plates 12 move along the outer surface of the slide rod 11 from both ends of the bidirectional lead screw 10 to the middle position of the bidirectional lead screw 10. The two guide plates 12 approach each other and move towards the automotive trim strip. When the rubber buffer sleeves 13 on both guide plates 12 are in contact with the automotive trim strip, the automotive trim strip is guided and positioned, so that the automotive trim strip is in the upper mold base. Directly below 5, hydraulic rod 3 is activated, controlling its extension. This causes the upper mold base 5 to descend via mounting plate 4, extending telescopic rod 7. Once the upper mold base 5 contacts the automotive trim strip and closes with the lower mold base 6, the trim strip is formed. During this process, the ejector block 20 slides into the receiving groove 19, and the movable block 22 slides downwards along the positioning rod 23 within the movable groove 21. Spring 24 is compressed and deformed. After the automotive trim strip is formed, hydraulic rod 3 is shortened, causing the upper mold base 5 to rise and return to its original position. During this process, spring 24 returns to its original position, pushing the movable block 22 upwards. This causes the movable block 22 to slide the ejector block 20 outwards from the receiving groove 19, lifting the automotive trim strip and completing the ejection process.

[0029] When the rubber buffer sleeve 13 needs to be replaced, first loosen the fixing bolt 18 so that the fixing bolt 18 extends away from the guide plate 12. After the fixing bolt 18 separates from the fixing block 17, the fixing of the rubber buffer sleeve 13 is released. Then, pull the rubber buffer sleeve 13 upward so that the rubber buffer sleeve 13 slides on the outer surface of the guide plate 12, the slider 14 slides inside the slide groove, the locking block 15 slides inside the locking groove 16, and the fixing block 17 slides inside the fixing groove. When the slider 14 slides out of the slide groove and the locking block 15 slides out of the locking groove 16, the disassembly of the rubber buffer sleeve 13 is completed. Then, take out the new rubber buffer sleeve 13 and reverse the above operation to install the new rubber buffer sleeve 13 onto the guide plate 12 to complete the replacement of the rubber buffer sleeve 13.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
