[0002] Rubber dust cover is a protective device made of rubber or highly elastic material, mainly used to seal and protect mechanical parts from the intrusion of external pollutants such as dust, sand, moisture, chemicals, etc., and also has oil-proof, corrosion-resistant, wind-proof and other properties. Rubber dust cover is usually formed by molding, especially the corrugated style dust cover, which requires a mold with optimized parting surface, and the cavity design needs to match the corrugated shape to ensure a smooth and defect-free surface after vulcanization.

[0037] During the blanking process of the rubber dust cover, the rubber dust cover is formed with the cooperation of the self-demolding core mechanism 4 and the two-group molding mold mechanism 6, and then the two groups of second electric push rods 5 drive the two-group molding mold mechanism 6 to open to both sides, and then the self-demolding core mechanism 4 automatically demolds the corrugated rubber dust cover and transfers it to the self-inspection feeding mechanism 7, the self-inspection feeding mechanism 7 transfers and inspects the rubber dust cover, and then the dividing plate 9 distinguishes the qualified rubber dust cover from the unqualified ones.

[0038] For example, Figure 3 and Figure 4As shown, the self-demolding core mechanism 4 includes a rotating shaft 401; a first motor 402 is provided on the rotating shaft 401; a mounting plate 403 is provided at one end of the first motor 402 away from the rotating shaft 401; a plurality of groups of first male molds 404 are distributed in a circular array on a side wall of the mounting plate 403 away from the first motor 402; a group of movable plates 405 are provided between two adjacent groups of the first male molds 404; a group of second male molds 406 are provided on each group of the movable plates 405; a plurality of groups of the first male molds 404, movable plates 405 and second male molds 406 are combined to form a core structure; a sealing plate 407 is provided at one end of the plurality of groups of movable plates 405 away from the mounting plate 403; a plurality of groups of slide grooves 408 are provided in a circular array on a side wall of the sealing plate 407 close to the movable plate 405; one end of each group of movable plates 405 away from the mounting plate 403 is slidably connected in a corresponding group of slide grooves 408; a plurality of groups of the first A guide rod 412 is provided between the male molds 404; a plurality of groups of sixth electric push rods 413 are arranged in a circular array on the outer wall of the guide rod 412; the output end of each group of the sixth electric push rods 413 is transmission-connected with a corresponding group of movable plates 405; a group of movable grooves 409 are provided on a side wall of each group of movable plates 405 away from the guide rod 412; each group of the second male molds 406 are movable through a corresponding group of movable grooves 409; a plurality of groups of fifth electric push rods 411 are evenly spaced on a side wall of each group of movable plates 405 close to the guide rod 412; the output end of each group of the fifth electric push rods 411 is transmission-connected with a corresponding group of second male molds 406; a plurality of groups of exhaust grooves 410 are evenly spaced on the two side walls of each group of the second male molds 406; the output end of the first motor 402 passes through the mounting plate 403 and is transmission-connected with a screw rod 414; the screw rod 414 is threadedly connected to the guide rod 412.

[0039] For example, Figure 5 As shown, the parting mold mechanism 6 includes a mold shell 601; a mold groove 602 is opened on one side wall of the mold shell 601; a plurality of groups of female mold grooves 603 are opened at equal intervals on the inner wall of the mold groove 602; each group of the first male mold 404 and the second male mold 406 are movable through the plurality of groups of female mold grooves 603.

[0040] The two-group molding die mechanism 6 is wrapped around the outer wall of the second male mold 406, and a mold cavity is formed by the molding groove 602, several groups of female mold grooves 603, several groups of first male molds 404, several groups of movable plates 405 and several groups of second male molds 406, which are used to extrude the rubber raw material at high temperature to form the corrugated rubber dust cover. When the molding work is completed, the two-group molding die mechanism 6 is unfolded to both sides, and then several groups of fifth electric push rods 411 are controlled to drive several groups of second male molds 406 to move to the side away from the guide rod 412, and several groups of exhaust grooves 410 are gradually exposed to the inside of the corrugated rubber dust cover. By inputting high-pressure gas into the inside of the dust cover, the adhesion between the corrugated rubber dust cover and the several groups of first male molds 404 and second male molds 406 is blown away, and then several groups of sixth electric push rods 413 are controlled to drive several groups of movable plates 405 to move to the side away from the guide rod 412 to open the corrugated rubber dust cover, and at the same time, the high-pressure gas input by the exhaust groove 410 can quickly The heat is discharged and taken away, and then the first motor 402 is controlled to drive the screw rod 414 to rotate. Under the threaded connection relationship between the screw rod 414 and the guide rod 412, and the guide rod 412 cannot rotate under the limiting action of the several groups of movable plates 405, so the guide rod 412 drives the corrugated rubber dust cover to move toward the side away from the mounting plate 403 through the several groups of second male molds 406, so that the corrugated rubber dust cover is separated from the several groups of first male molds 404, and then the movable plate 405 and the second male mold 406 are controlled to shrink at the same time, and then the rotating shaft 401 is controlled to drive the mounting plate 403 to rotate through the first motor 402, so that the corrugated rubber dust cover can directly slide off the outer wall of the several groups of movable plates 405, which can not only quickly complete the demoulding work, but also prevent the corrugated rubber dust cover from sticking to the mold core, thereby improving the demoulding and blanking work effect, and can also quickly cool down the corrugated rubber dust cover after molding, thereby improving the cooling efficiency after demoulding and blanking.

[0041] For example, Figure 6 and Figure 7As shown, the self-inspection feeding mechanism 7 includes a feed tube 701; a feed hopper 702 is provided on the top of the feed tube 701; two groups of conveyor belts 703 are symmetrically provided on the two side walls of the feed hopper 702; a number of groups of alignment blocks 704 are evenly distributed on the outer wall of each group of the conveyor belts 703; each group of the alignment blocks 704 is inclined along the conveying direction; two groups of threaded columns 705 are provided in the feed tube 701; the thread directions of the two groups of threaded columns 705 are the same, and the rotation directions are the same; the feed tube A plurality of detection cameras 706 are evenly spaced on the inner wall at the top of 701; two groups of grooves 707 are symmetrically provided on the inner walls on both sides of the discharge pipe 701; a group of air guide tubes 708 are provided on the inner wall on the side away from the threaded column 705 of each group of grooves 707; each group of air guide tubes 708 are connected to the output end of the filter fan 8; a plurality of air injection tubes 709 are evenly spaced on the outer wall of each group of air guide tubes 708; the opening of each group of air injection tubes 709 faces the corresponding group of threaded columns 705.

[0042] After demolding, the rubber dust cover slides into the discharge hopper 702, and the two groups of conveyor belts 703 rotate toward the center. Under the action of several groups of inclined calibration blocks 704, the position of the rubber dust cover is adjusted to be level with the discharge tube 701, and then the rubber dust cover falls on the top of the two groups of threaded columns 705. The two groups of threaded columns 705 rotate in the same direction, which will apply an axial force for horizontal movement and a tangential force for rotation to the rubber dust cover, so that the rubber dust cover rotates simultaneously during the movement of the discharge, and cooperates with several groups of detection cameras 706, so that the rubber dust cover can be fully inspected, avoiding the problem of low efficiency of manual inspection and improving the work quality of demolding and discharge. At the same time, during the unloading process of the rubber dust cover, the filter fan 8 sprays air through two groups of air guide pipes 708 and several groups of air injection pipes 709, so that the contact parts between the two groups of threaded columns 705 and the rubber dust cover are quickly cooled down, and at the same time, positive air pressure can be formed in the unloading pipe 701, and then the gas is discharged through the unloading end and the unloading hopper 702, which can not only prevent dust from entering and contaminating the rubber dust cover, but also cushion the rubber dust cover entering from the unloading hopper 702, avoid the rubber dust cover from falling too fast and causing impact, and improve the safety of demolding and unloading.

[0043] For example, Figure 8 As shown, the adjustable walking mechanism 16 includes a mounting column 1601; a support block 1602 is rotatably connected inside the mounting column 1601; the support block 1602 is a polygonal column; a second motor 1603 is provided on one side wall of the support block 1602; the output end of the second motor 1603 is transmission-connected to the support block 1602; a spherical wheel 1604 is hinged on one side wall of the support block 1602.

[0044] During the use of the unloading device, several groups of second motors 1603 are controlled to drive several groups of support blocks 1602 to rotate, so that several groups of spherical wheels 1604 rotate to the bottom, and then several groups of fourth electric push rods 15 can be controlled to drive several groups of mounting columns 1601 to descend, so that several groups of spherical wheels 1604 are in contact with the ground and lift the unloading device, and then the unloading device can be pushed to move, and shock-absorbing and anti-slip pads can be added to other sides of the support block 1602. When the support block 1602 rotates so that the support surface is located at the bottom, it can cooperate with the horizontal sensor to keep the unloading device always level, thereby improving the convenience of using the unloading device.

[0045] The corrugated rubber dust cover is opened by controlling several groups of movable plates 405 to move outward, and at the same time, the high-pressure gas input from the exhaust groove 410 can be quickly discharged and take away the heat, and then the guide rod 412 drives the corrugated rubber dust cover to move toward the side away from the mounting plate 403, so that the corrugated rubber dust cover is separated from several groups of first male molds 404, and then the movable plate 405 and the second male mold 406 are controlled to shrink at the same time and the self-demolding core mechanism 4 is controlled to tilt, so that the corrugated rubber dust cover can slide directly, which not only can quickly complete the demoulding work and improve the demoulding and blanking work effect, but also can quickly cool down the corrugated rubber dust cover after molding, thereby improving the cooling efficiency after demoulding and blanking.

[0046] After demolding, the rubber dust cover slides into the discharge hopper 702, and the two groups of conveyor belts 703 rotate toward the center. Under the action of several groups of inclined calibration blocks 704, the position of the rubber dust cover is adjusted to be level with the discharge tube 701, and then the rubber dust cover falls on the top of the two groups of threaded columns 705. The two groups of threaded columns 705 rotate in the same direction, which will apply an axial force for horizontal movement and a tangential force for rotation to the rubber dust cover, so that the rubber dust cover rotates simultaneously during the movement of the discharge, and cooperates with several groups of detection cameras 706, so that the rubber dust cover can be fully inspected, avoiding the problem of low efficiency of manual inspection and improving the work quality of demolding and discharge.

[0047] During the unloading process of the rubber dust cover, the filter fan 8 sprays air through two groups of air guide pipes 708 and several groups of air injection pipes 709, so that the contact parts between the two groups of threaded columns 705 and the rubber dust cover are quickly cooled down, and at the same time, positive air pressure can be formed in the unloading pipe 701. Then the gas is discharged through the unloading end and the unloading hopper 702, which can not only prevent dust from entering and contaminating the rubber dust cover, but also cushion the rubber dust cover entering from the unloading hopper 702, avoid the rubber dust cover from falling too fast and causing impact, and improve the safety of demolding and unloading.

[0048] By controlling several groups of second motors 1603 to drive several groups of support blocks 1602 to rotate, several groups of spherical wheels 1604 can be rotated to the bottom, and then several groups of fourth electric push rods 15 can be controlled to drive several groups of mounting columns 1601 to descend, so that several groups of spherical wheels 1604 are in contact with the ground and lift the unloading device, and then the unloading device can be pushed to move, and shock-absorbing and anti-slip pads can be added to other sides of the support block 1602. When the support block 1602 rotates so that the supporting surface is located at the bottom, the horizontal sensor can be used to ensure that the unloading device always remains horizontal, thereby improving the ease of use of the unloading device.
