Description

Technical Field

[0002] A dust cover is used on the brake caliper of the car to prevent dust from entering the piston gap when braking. At the same time, it can effectively prevent the piston surface from being stuck, the sealing ring from being damaged, and causing oil leakage and brake failure, thereby extending the service life of the caliper.

[0003] The traditional production method of dust cover is that the operator stands in front of the equipment.

[0039] Specifically, the molding template 3 is installed on the retaining frame 1 40 and the retaining frame 2 41 respectively, and the molding template 3 is lifted up by the lifting platform 13 to cooperate with the upper mold frame 5, and extrusion molding is carried out in combination with the extrusion part, and then the molding template 3 is controlled to descend and enter the demoulding stage. The molding template 3 on the retaining frame 2 41 is transferred to the lifting platform 13 by the shifting mechanism 7, and the demoulding operation is started, while the retaining frame 1 40 and the molding template 3 thereon continue to be lifted up in combination with the lifting motor 100 and cooperate with the upper mold frame 5, and extrusion molding is carried out in combination with the extrusion part. After extrusion molding, it returns to the initial height and contacts with the heating platform 20 on the mounting frame 1 2 to maintain the temperature of the molding template 3, which is convenient for subsequent demoulding processing.

[0040] Further, such as Figure 3 , Figure 4 As shown, the retainer 1 40 and the retainer 2 41 are arranged in a split type, and the retainer 1 40 and the retainer 2 41 are provided with a clamping slot 42 on the side facing the forming template 3, and two groups of sliding frames 30 are slidably installed in the clamping slot 42, and the two groups of sliding frames 30 are respectively arranged on both sides of the forming template 3, and the sliding frame 30 is installed with an electric telescopic column 1 33, and the electric telescopic column 1 33 is connected to the clamping frame 31, and the clamping frame 31 is provided with a clamping block 32, and the bottom of the lower mold frame 300 is correspondingly provided with a clamping slot 301, and the clamping slot 301 and the clamping block 32 cooperate with each other.

[0043] Specifically, the adjustment cylinder 1 400 and the adjustment cylinder 2 410 can adjust the distance between the retainer 1 40 and the retainer 2 41 and the spacing between the retainer 1 40 and the mounting frame 1 2, so as to facilitate the control of the docking between the retainer 1 40 or the retainer 2 41 and the lifting platform 13. At the same time, it is convenient to control the contact between the molding template 3 and the heating platform 20 on the mounting frame 1 2, maintain the temperature of the molding template 3, and avoid the temperature drop caused by the waiting time too long when demolding in turn, which affects the demolding and the subsequent vulcanization treatment quality.

[0044] Further, such as Figure 4 , Figure 7 , Figure 8 As shown, the shifting mechanism 7 includes a mating rack 700 arranged on the lifting platform 13, the middle of the lifting platform 13 is hollowed out, and two mating racks 700 are symmetrically arranged. Extended racks 43 are arranged at the positions corresponding to the mating racks 700 on the retaining frame 1 40 and the retaining frame 2 41, and an adsorption frame 702 is arranged on the sliding frame 30. Both ends of the adsorption frame 702 are installed with mating gears 703, and the mating gears 703 and the mating racks 700 are meshed with each other.

[0045] Specifically, the adsorption frame 702 is first adsorbed on the sliding frame 30, and the driving motor drives the mating gears 703 at both ends to mesh with the mating racks 700, thereby driving the forming template 3 to be transferred from the retaining frame 1 40 or the retaining frame 2 41 to the lifting platform 13. The extended racks 43 are arranged on the retaining frame 1 40 and the retaining frame 2 41, so that the shifting mechanism 7 can return the forming template 3 after the demoulding process to the retaining frame 1 40 or the retaining frame 2 41, so as to perform the vulcanization process or re-extrusion molding operation. The clamping slide grooves 42 are extended to both sides of the hollow part of the lifting platform 13.

[0046] Further, such as Figure 7 , Figure 8 As shown, the lifting platform 13 is also connected to a lifting component 6, and the lifting component 6 includes four adjusting cylinders 3 60 arranged at the bottom of the mounting frame 2 11, and the adjusting cylinder 3 60 passes through the lifting platform 13 and is connected to a horizontal frame 61, and a telescopic motor 1 62 is horizontally arranged on the horizontal frame 61, and the telescopic motor 1 62 is connected to a docking block 1 63, and docking holes 305 are arranged on both sides of the middle mold frame 306, and the docking block 1 63 cooperates with the docking hole 305, and four lifting cylinders 14 are also arranged at the bottom of the mounting frame 2 11, and the lifting cylinder 14 passes through the mounting frame 2 11 and is connected to the lifting platform 13.

[0048] Further, such as Fig. 9 , Fig.10 , Fig.11 As shown, the demoulding mechanism 8 also includes an installation box 80, and an electric telescopic column 81 is horizontally arranged on the side of the installation box 80. The end of the electric telescopic column 81 is connected to the bottom of the base 82, and the end of the electric telescopic column 81 is rotatably connected to a telescopic rod 86, a telescopic motor 87, and an articulated frame 88. The telescopic rod 86 is connected to a lifting plate 85, and the articulated frame 88 is connected to a fixed plate 84.

[0049] Specifically, when the middle mold frame 306 carrying the middle module 303 and the dust cover body 304 rises to the height of the demoulding mechanism 8, the electric telescopic column 2 81 is used to control the bottom bracket 82 to move out of the installation box 80, so that the ejector 83 on the bottom bracket 82 falls directly below the middle module 303. At this time, the middle mold frame 306 is driven to descend in combination with the regulating cylinder 3 60, and the ejector 83 ejects the dust cover body 304 from the middle module 303. At this time, the center of the dust cover body 304 is a columnar shape left during extrusion molding. The runner enters the middle of the elastic rod 811, and continues to drive the lifting plate 85 to rise through the telescopic motor 87, so that the plug-in column 89 and the matching flange 813 move up, and then the elastic rod 811 clamps the columnar runner in the center of the dust cover body 304, and then the lifting plate 85 and the fixed plate 84 are flipped over as a whole, and the dust cover body 304 is de-burred. The dust cover body 304 with de-burred edges is continued to be put back into the middle module 303 of the middle mold frame 306 to facilitate subsequent vulcanization treatment.

[0052] S3, control the lifting platform 13 to descend to the lowest point, and combine with the electric telescopic column to drive the clamping block 32 to separate from the clamping groove 301 on the lower mold frame 300, and the lower mold frame 300 remains on the heating table 20. The telescopic motor 162 drives the docking block 163 to cooperate with the docking hole 305 on the side of the middle mold frame 306, and then combines with the lifting component 6 to drive the middle mold frame 306 to rise.

The adsorption frame 702 is first adsorbed on the sliding frame 30, and the driving motor drives the matching gears 703 at both ends to mesh with the matching racks 700, thereby driving the molding template 3 to be transferred from the retaining frame 1 40 or the retaining frame 2 41 to the lifting platform 13. The extended racks 43 are arranged on the retaining frame 1 40 and the retaining frame 2 41, so that the shifting mechanism 7 can return the molding template 3 after the demoulding process to the retaining frame 1 40 or the retaining frame 2 41, so as to perform the vulcanization process or re-extrusion molding operation. The lifting platform 13 is driven to rise and fall by the lifting cylinder 14, so as to control the lifting platform 13 to dock with the retaining frame 1 40 or the retaining frame 2 41, so as to facilitate the transfer of the forming template 3 to the lifting platform 13, and the lower mold frame 300 can be separated from the heating platform 20 by combining with the electric telescopic column 1 33, the clamping frame 31 and the clamping block 32 arranged around the forming template 3. While keeping the lower mold frame 300 warm, the middle mold frame 306 of the forming template 3 is lifted and lowered by the adjusting cylinder 3 60, the telescopic motor 1 62 and the docking block 1 63, and the demolding process is performed in combination with the demolding mechanism 8.When the middle mold frame 306 carrying the middle module 303 and the dust cover body 304 rises to the height of the demoulding mechanism 8, the electric telescopic column 2 81 is used to control the bottom bracket 82 to move out of the installation box 80, so that the ejector 83 on the bottom bracket 82 falls directly below the middle module 303. At this time, the regulating cylinder 3 60 drives the middle mold frame 306 to descend, and the ejector 83 ejects the dust cover body 304 from the middle module 303. At this time, the center of the dust cover body 304 is in the columnar runner left during extrusion molding. Enter the middle of the elastic rod 811, and continue to drive the lifting plate 85 to rise through the telescopic motor 87, so that the plug-in column 89 and the matching flange 813 move up, so that the elastic rod 811 clamps the columnar runner in the center of the dust cover body 304, and then flips the lifting plate 85 and the fixed plate 84 as a whole, and removes the flash of the dust cover body 304. The dust cover body 304 with the flash removed is continued to be put back into the middle module 303 of the middle mold frame 306 to facilitate subsequent vulcanization treatment.
