Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold for processing automobile interior decoration parts with a buffering function. Background Art

[0002] In the production process of automobiles, some of the interior trims are usually plastic products. The molding of trims needs to be completed through molds. They are usually composed of two parts: a movable mold and a fixed mold. The two parts can be separated or combined. When separated, the parts are taken out, and when combined, the blanks are injected into the mold cavity for molding. In the production process, the mold has the functions of improving production efficiency, ensuring product quality, realizing production customization and promoting industrialized production.

[0003] After searching, Chinese patent announcement number: CN213107716U discloses a mold for processing automobile interior decoration parts. Baffles are provided on both sides of the die-stamping table, and a locking rod is provided in the baffle. A rubber head is provided on one side of the locking rod. A spring frame C is sleeved between the baffle and the locking rod. When fixing the mold, the locking rod is pulled to both sides to clamp the mold inside the rubber head. The elastic force generated by the spring frame C is used to lock the mold. The operation is convenient and quick. The rubber head can also effectively protect the plastic mold and increase the service life of the plastic mold.

[0004] In the above technical solution, a locking rod is used in conjunction with a spring frame and other structures to provide buffering protection for the mold. However, the upper mold will cause a certain impact on the lower mold when it contacts the upper mold. The upper mold lacks multiple buffering functions during its lifting and lowering process, which reduces the buffering effect. As a result, the stability of the upper and lower molds cannot be guaranteed during use. Therefore, a automotive interior decoration parts processing mold with a buffering function is proposed to solve the above problem. Utility Model Content

The material of the fixing block 707 is the same as that of the contact block 705. Both have anti-slip function and soft characteristics that can produce deformation. An airbag 708 is provided inside the guide groove 703, and an air inlet 709 is provided on the surface of the airbag 708. A telescopic spring 710 is fixedly connected to the inner wall of the airbag 708. The telescopic spring 710 is deformed when the airbag 708 is compressed by force, and helps the airbag 708 to reset after the airbag 708 is separated from the external squeezing force. An air pipe 711 is fixedly connected to the inside of the airbag 708, and a one-way valve 712 is provided on the surface of the air pipe 711. The setting of the one-way valve 712 enables the air pipe 711 to only discharge the air inside the airbag 708, but not to introduce air into it.

[0035] Reference Figure 3-Figure 4, one end of the support rod 701 away from the guide block 702 is hinged on the outer wall of the upper mold 5, and the side of the guide block 702 away from the support rod 701 is slidably connected to the inner wall of the guide groove 703, and the guide groove 703 provides a predetermined movement trajectory for the guide block 702, and the contact block 705 is meshed with the fixed block 707. There are four groups of contact blocks 705, and the Suzi contact blocks 705 are arranged in pairs in a mirror image with the center point of each group of guide blocks 702 as the symmetry axis. There are several groups of fixed blocks 707, and several groups of fixed blocks 707 are arranged in a mirror image at equal distances inside each group of guide grooves 703. The side of the contact block 705 close to the lower mold 6 is arranged in an inclined surface, and the side of the fixed block 707 close to the airbag 708 is arranged in an inclined surface. When the guide block 702 moves outward, the fixed block 70 7 contacts with the parallel surface of the contact block 705, the fixed block 707 provides resistance to the movement of the contact block 705, when the guide block 702 moves inward, the fixed block 707 contacts with the inclined surface of the contact block 705, reducing the resistance to the guide block 702, the end of the buffer spring 704 away from the inner wall of the guide groove 703 is fixedly connected to the outer wall of the guide block 702, the buffer spring 704 is located on the side of the guide groove 703 close to the lower mold 6, the air inlet 709 is provided on the side of the airbag 708 close to the lower mold 6, the end of the air pipe 711 away from the airbag 708 passes through the inner wall of the lower mold 6, the inner wall of the lower mold 6 is provided with an exhaust hole, one end of the exhaust hole is connected to the air pipe 711, and the other end is located at the upper end of the inner wall of the lower mold 6, and the exhaust holes on both sides are not on the same horizontal line.

[0036] Reference Figure 5 The surface of the mounting plate 706 is provided with an adjustment structure 8, which includes a threaded block 801, the inner wall of the threaded block 801 is threadedly connected with a threaded rod 802, and the top of the threaded rod 802 is fixedly connected with a knob 803. When the control knob 803 rotates, the threaded rod 801 will rotate accordingly. The outer wall of the threaded block 801 is fixedly connected to the outer wall of the mounting plate 706 away from the lower mold 6, and the outer wall of the threaded block 801 is attached to the inner wall of the guide groove 703. The end of the threaded rod 802 away from the knob 803 is rotatably connected to the inner wall of the guide groove 703. The forward or reverse rotation of the knob 803 can make the threaded rod 802 drive the threaded block 802 to rotate forward or reverse, so that the threaded block 801 drives the mounting plate 706 to rise and fall, thereby adjusting the degree of engagement between the fixed block 707 and the contact block 705, thereby adjusting the degree of resistance provided by the fixed block 707 to the contact block 705.

[0037] Working principle: the hydraulic cylinder 4 is started to drive the upper mold 5 to gradually descend until it is embedded in the lower mold 6. When the upper mold 5 is on the way down, the support rod 701 will drive the guide block 702 to gradually slide outward inside the guide groove 703. At this time, the buffer spring 704 is deformed by force and is in a stretched state. At the same time, the contact block 705 is meshed with the fixed block 707 in turn. The fixed block 707 will provide a certain resistance to the contact block 705. When the upper mold 5 is close to the lower mold 6, the guide block 702 squeezes the airbag 708. At this time, the air inlet 709 is blocked by the guide block 702, and the telescopic spring 710 is in a compressed state. The air inside the airbag 708 is discharged through the air pipe 711, and then blown to the bottom of the upper mold 5 through the discharge hole to blow away the dust on its surface. At the same time, the airbag 708 provides a certain buffering force to the guide block 702, lowering the lower mold 5. There is a risk of damage to the mold due to the large impact force on the way the upper mold 5 is mating with the lower mold 6. When the upper mold 5 moves away from the lower mold 6, the support rod 701 will carry the guide block 702 to move inward inside the guide groove 703. The buffer spring 704 will quickly recover its deformation after losing pressure. At the same time, the meeting of the inclined surface of the fixed block 707 and the contact block 705 will reduce the resistance to the movement of the guide block 702. After the airbag 708 loses its extrusion force, it will be reset through the telescopic spring 710 and then the air will be drawn in through the air inlet 709 to ensure the subsequent dust cleaning of the upper mold 5. When it is necessary to adjust the degree of buffering between the upper mold 5 and the lower mold 6, the knob 803 is turned forward or reversed to make the threaded rod 802 drive the mounting plate 706 to rise and fall. According to the degree of engagement between the fixed block 707 and the contact block 705, the strength of the buffering is switched.

[0038] Finally, it should be noted that the above are only 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 aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
