Description

Technical Field

[0001] The present invention relates to the technical field of zipper production equipment, and particularly relates to an injection molding processing equipment for conductive plastic zippers. Background Art

[0002] In order to make the injection molding part of the existing injection molded pull head have a metallic luster, electroplating treatment needs to be carried out on the injection molding part. However, since the existing injection molded pull head uses plastic pellets as raw materials, the injection molding part does not have a conductive function. Therefore, conductive plastic pellets are replaced for injection molding, and the injection molded product can be conductive and can be directly electroplated. The manufacturing method of the existing injection molded pull head is that the small rope loop of the eight-shaped steel wire rope is manually placed in the groove set on the mold, the eight-shaped steel wire rope is clamped by the groove, and then the middle part of the eight-shaped steel wire rope is injection molded to make an injection molded pull head with two rope loops. When placing, it is difficult for manual operation to press it into the groove, and the phenomenon that the eight-shaped steel wire rope does not fit the groove easily occurs. Then, manual operation needs to comb it many times to make it flat, which is cumbersome and has low efficiency, and it is difficult to produce quickly and in large quantities.

[0003] When the eight-shaped steel wire rope is produced, two rope loops are formed by twisting the two ends of a steel wire rope to the middle respectively. The two rope loops are one large and one small, and the whole is in the shape of an eight. Then, the two ends of the steel wire rope are locked by fasteners. However, the steel wire rope is a long round rope, and it is easy for the steel wire rope to twist during the bundling process. And because the length of the round rope on the side of the large rope loop is much longer than that on the side of the small rope loop, it is easier for the large rope loop to twist, and then the large rope loop twists to form knots or chain links, that is, it generates twisting. And because both ends of the steel wire rope have been fixed in the middle section, the torsion cannot be released, resulting in the twisting cannot be eliminated. When injecting it, it is difficult to bundle the large rope loop of the eight-shaped steel wire rope, so it is difficult to fix the eight-shaped steel wire rope on the mold, and the large rope loop of the steel wire rope of the produced injection molded pull head will still generate twisting, seriously affecting the appearance of the injection molded pull head. Summary of the Invention

[0004] In order to overcome the disadvantages that when producing injection molded pull heads, the efficiency of manually fixing the eight-shaped steel wire rope is low, it is difficult to produce quickly and in large quantities, and the appearance of the injection molded pull heads produced by using the eight-shaped steel wire ropes with twisting is not good, the present invention provides an injection molding processing equipment for conductive plastic zippers.

[0035] As Figure 3 shown, the second power assembly includes a second push rod 111, a motor 112, and a third push rod 121; the second push rod 111 is installed at the left end of the L-shaped part on the first mounting plate 6; the telescopic part of the second push rod 111 is bolted to the motor 112, and the output shaft of the motor 112 passes through the hole opened on the telescopic part of the second push rod 111 and is fixedly connected to the T-shaped limit plate 7.

[0036] As Figure 3 shown, the clamping assembly includes a third push rod 121 and a pressing block 122; the third push rod 121 is installed in the middle of the lower side of the L-shaped part on the first mounting plate 6; the telescopic part of the third push rod 121 is fixedly connected to the pressing block 122.

[0037] As Figures 5-6As shown in the figure, eight semi-elliptical injection grooves 3a are designed on the lower mold 3; a first wire clamping groove 3b is designed on the left side of each injection groove 3a, two second wire clamping grooves 3c and a third wire clamping groove 3d are designed on the right side of each injection groove 3a, and each second wire clamping groove 3c is located to the left of the corresponding third wire clamping groove 3d; a first heightening part 3e is designed in each first wire clamping groove 3b; a second heightening part 3f is designed between every two second wire clamping grooves 3c, and the second heightening part 3f is designed with a rounded corner for guiding the figure-eight wire rope 100, facilitating the spherical head L-shaped rod 8 to press the figure-eight wire rope 100 into the second wire clamping groove 3c; a third heightening part 3g is designed on the front side and the rear side of each third wire clamping groove 3d; the first wire clamping groove 3b, the second wire clamping groove 3c and the third wire clamping groove 3d are all used to fix the figure-eight wire rope 100, wherein the first wire clamping groove 3b is used to fix the small wire loop 100a, and the second wire clamping groove 3c and the third wire clamping groove 3d cooperate to fix the large wire loop 100b; grooves matching the lower mold 3 are arranged on the upper mold 4 to realize the injection molding of the injection pull head 200.

[0038] As Figure 5 shown, the third wire clamping groove 3d is an inverted T-shaped groove. When used for clamping the figure-eight wire rope 100, it can be naturally opened, further avoiding the large wire loop 100b from being bent again.

[0039] The working principle of the above-mentioned Embodiment 1 is as follows: After the equipment is started, first, the first moving block 102 is controlled to drive the conveyor belt 5 and the first mounting plate 6 to move forward, so that the conveyor belt 5 is located on the right side of the last first wire clamping groove 3b. Then, the telescopic part of the first push rod 103 is extended to push the conveyor belt 5 and the first mounting plate 6 to move leftward, so that the left port of the conveyor belt 5 is located above the last first wire clamping groove 3b. Then, the conveyor belt 5 drives the limiting group to move to the position as Figure 2 shown. After that, the figure-eight wire rope 100 is placed on the limiting group manually. The middle part of the figure-eight wire rope 100 is fixed by the cooperation of the eight limiting parts 5a of the limiting group. Then, the conveyor belt 5 drives the figure-eight wire rope 100 to be conveyed leftward under the first mounting plate 6. During the conveying process, when the figure-eight wire rope 100 is conveyed to the left port of the conveyor belt 5, the small wire loop 100a will continuously break away from the conveyor belt 5. During this process, the small wire loop 100a sags under the influence of its own weight. When the end of the small wire loop 100a contacts the lower mold 3, at this time, the end of the small wire loop 100a is located to the left of the first wire clamping groove 3b and under the T-shaped limiting plate 7. The conveyor belt 5 stops working. Then, the telescopic part of the second push rod 111 is extended to push the T-shaped limiting plate 7 and the two spherical head L-shaped rods 8 to move downward together. At the same time, the motor 112 is controlled to drive the T-shaped limiting plate 7 and the spherical head L-shaped rods 8 to rotate clockwise so that the T-shaped limiting plate 7 and the spherical head L-shaped rods 8 rotate from the state as Figure 3 shown to the state asFigure 4 In the state shown, at this time, the T-shaped limit plate 7 and the parts connected thereto are tilted upward as a whole. When the spherical head L-shaped rod 8 is about to contact the lower mold 3, the T-shaped limit plate 7 and the spherical head L-shaped rod 8 are driven to rotate counterclockwise by controlling the motor 112. During this process, the two spherical head L-shaped rods 8 cooperate with each other to push the end of the small rope loop 100a to move to the right in the form of a hook, and then snap into the left end of the first wire clamping groove 3b. At this time, the pressing portion 7a is in contact with the first heightened portion 3e and is parallel to the first heightened portion 3e. Then the telescopic portion of the first push rod 103 is controlled to retract to drive the conveyor belt 5 and the parts connected to the conveyor belt 5 to move to the right. At the same time, the conveyor belt 5 synchronizes with the first push rod 1 03 pushes the speed of the conveyor belt 5 and continues to convey the figure-eight steel wire rope 100, so that the figure-eight steel wire rope 100 is continuously separated from the left end of the conveyor belt 5. During this process, the spherical parts of the two spherical head L-shaped rods 8 are stretched open by the first elevated part 3e, and both springs are in a compressed state. Then, during the movement, the two spherical head L-shaped rods 8 are pushed by the corresponding fit, and the spherical parts of the spherical head L-shaped rods 8 are always in fit with the side of the first elevated part 3e. Then, the spherical parts of the two spherical head L-shaped rods 8 will continuously clamp the small rope loop 100a into the first wire clamping groove 3b. Through the above method, the small rope loop 100a is quickly clamped into the first wire clamping groove 3b, avoiding the difficulty of manually pressing it into the groove.

[0040] It should be noted that since the pressing part 7a contacts the first raised part 3e in advance and the pressing part 7a has a guiding function, during the movement process, the pressing part 7a will continuously push the small rope loop 100a to move to both sides of the first raised part 3e, thereby facilitating the two spherical head L-shaped rods 8 to clamp the small rope loop 100a into the first wire clamping groove 3b.

[0041] After the small rope loop 100a is completely clamped into the first wire clamping groove 3b, the conveyor belt 5 stops working. At this time, the middle section of the figure-eight steel wire rope 100 is exactly below the pressing block 122. The two spherical head L-shaped rods 8 have disengaged from the first heightening part 3e and are located to the right of the first heightening part 3e. The right part of the small rope loop 100a is constrained between the spherical parts of the two spherical head L-shaped rods 8. Then, first, control the third push rod 121 to push the pressing block 122 downward to make the pressing block 122 contact the middle section of the figure-eight steel wire rope 100. At this time, the eight limiting parts 5a cooperate with the pressing block 122 to restrict the middle section of the figure-eight steel wire rope 100. Subsequently, control the telescopic part of the first push rod 103 to retract, driving the conveyor belt 5 and the parts connected to the conveyor belt 5 to move to the right. During this process, since the small rope loop 100a has been clamped into the first wire clamping groove 3b, the right side of the figure-eight steel wire rope 100 will continuously be drawn out from between the eight limiting parts 5a and the pressing block 122. And during the drawing-out process, the large rope loop 100b is constrained into a linear shape by the cooperation of the eight limiting parts 5a and the pressing block 122. And during this process, the middle section of the figure-eight steel wire rope 100 and the large rope loop 100b being drawn out will still be located between the two spherical head L-shaped rods 8. When the two spherical head L-shaped rods 8 drive the large rope loop 100b constrained into a linear shape to move to the left of the second wire clamping groove 3c, since at this time, the pressing part 7a is located between the large rope loop 100b constrained into a linear shape and the pressing part 7a passes over the second heightening part 3f. At this time, and because the second heightening part 3f is designed with a rounded corner and has a guiding function, the constrained large rope loop 100b will pass by both sides of the second heightening part 3f. Then, the ropes of the large rope loop 100b are respectively clamped into the corresponding second wire clamping grooves 3c through the spherical parts of the two spherical head L-shaped rods 8. Subsequently, the conveyor belt 5 continues to move to the right to draw out the figure-eight steel wire rope 100. When the spherical parts of the two spherical head L-shaped rods 8 move to the left of the third wire clamping groove 3d, control the second push rod 111 to drive the spherical head L-shaped rods 8 to bypass the third heightening part 3g and then press the large rope loop 100b from the right port of the third heightening part 3g to make the large rope loop 100b completely enter the third wire clamping groove 3d.

[0042] After the figure-eight steel wire rope 100 is completely fixed, drive the conveyor belt 5 and the parts connected to the conveyor belt 5 to move intermittently through the first moving block 102. Then move the conveyor belt 5 to the right of the corresponding first wire clamping groove 3b. Then, in the same way as above, clamp other figure-eight steel wire ropes 100 onto the lower mold 3. After completing the feeding work for a group of figure-eight steel wire ropes 100, control the first power assembly to drive the conveyor belt 5, the first mounting plate 6, the T-shaped limiting plate 7, and the spherical head L-shaped rods 8 to move to a position that does not affect the normal operation of the vertical injection molding machine 2, that is, a position convenient for manual feeding. Then, control the vertical injection molding machine 2 to drive the upper mold 4 to move downward to fit with the lower mold 3. Then, after controlling the correction system to correct the figure-eight steel wire rope 100, carry out the injection molding work. After completing the injection molding work, the product is obtained asFigure 12 The shown injection-molded pull head 200, then drive the upper mold 4 to reset by controlling the vertical injection molding machine 2, and finally control the discharging system to perform demolding and transfer work, thereby completing the injection molding work on a group of figure-eight steel wire ropes 100.

[0043] Embodiment 2

[0044] Based on Embodiment 1, as Figures 7-8 shown, the correction system includes correction components. The opposite sides of the lower platen and the upper platen of the vertical injection molding machine 2 are jointly connected with correction components corresponding to the number of the second card slots 3c; the correction components are composed of four correction units; two correction units are connected to the lower platen of the vertical injection molding machine 2, and the two correction units on the lower platen are symmetric left and right; the other two correction units are connected to the upper platen of the vertical injection molding machine 2, and the two correction units on the upper platen are symmetric left and right; the correction unit on the lower platen and the corresponding correction unit on the upper platen are centrosymmetric; each correction unit is composed of a fourth push rod 201, a chuck 202, a first connecting pipe 203 and a rubbing plate 204; a chuck 202 is fixedly connected to the telescopic part of the fourth push rod 201, and the chuck 202 is made of aluminum alloy material; a strip-shaped cavity 202a is designed on the right side of the chuck 202; the lower end of the strip-shaped cavity 202a communicates with a first connecting pipe 203; the first connecting pipe 203 communicates with an external micro air pump; a rubbing plate 204 is slidably connected in the strip-shaped cavity 202a, and gas is introduced into the strip-shaped cavity 202a through the first connecting pipe 203, thereby pushing the rubbing plate 204 to pop up, thereby rubbing the large rope loop 100b and driving it to rotate, thereby correcting it; a strip-shaped groove 202b is designed on the left side of the chuck 202 for reserving a pop-up space for the rubbing plate 204; a contact sensor is installed on the lower surface of the first mounting plate 6, and whether the large rope loop 100b is warped is detected through the contact sensor, and then whether the large rope loop 100b is twisted is detected; two through holes are designed between the second card slot 3c and the third card slot 3d on each lower mold 3, and through holes are also opened at the corresponding positions on each upper mold 4 for enabling the fourth push rod 201 and the chuck 202 to pass through the lower mold 3 and the upper mold 4 and then cooperate to clamp the figure-eight steel wire rope 100; the fourth push rod 201, the chuck 202, the first connecting pipe 203 and the rubbing plate 204 in the same vertical direction and the fourth push rod 201, the chuck 202, the first connecting pipe 203 and the rubbing plate 204 below are centrosymmetric, so that when the two rubbing plates 204 pop up together, they cooperate to complete the rubbing action on the figure-eight steel wire rope 100.

[0045] One side of the rubbing plate 204 is wavy, which is used to improve the rubbing effect on the large rope loop 100b, and thus improve the correction effect on the figure-eight steel wire rope 100.

[0046] The working principle of the above-mentioned Embodiment 2 is as follows: When the device is working, if a figure-eight steel wire rope 100 with a twisted large rope loop 100b is obtained manually, first, the two ends of the figure-eight steel wire rope 100 are held by hand and rotated. After the figure-eight steel wire rope 100 is corrected, the figure-eight steel wire rope 100 is fixed on the conveyor belt 5 by the limiting group for conveying. It should be noted that after the figure-eight steel wire rope 100 is fixed on the limiting group, the large rope loop 100b needs to be pressed on the conveyor belt 5 by hand until the figure-eight steel wire rope 100 is completely transported under the first mounting plate 6 to prevent the large rope loop 100b from being twisted again. After the figure-eight steel wire rope 100 enters under the first mounting plate 6, the twisting tendency of the large rope loop 100b forces one side of it to tilt up, contact the first mounting plate 6 and be limited by it, and trigger the contact sensor on the lower surface of the first mounting plate 6. After the contact sensor detects the contact signal, it transmits the signal to the controller. If the contact signal is detected inside the contact sensor, the controller determines that the large rope loop 100b is twisted counterclockwise when viewed from right to left. If the contact signal is detected outside the contact sensor, the controller determines that the large rope loop 100b is twisted clockwise when viewed from right to left, and then the twisting direction of the large rope loop 100b is judged. Taking Figure 11 the state shown as an example, if the figure-eight steel wire rope 100 is twisted in this state, that is, the rear side of the large rope loop 100b tilts up, the contact sensor inside the lower surface of the first mounting plate 6 will be triggered, and then it is judged by the controller that the figure-eight steel wire rope 100 is twisted counterclockwise when viewed from right to left.

[0047] Subsequently, after continuing to complete the fixing work of the figure-eight steel wire rope 100, after completing the pressing-down action of the upper die 4, a set of correction components for fixing the position of the large rope loop 100b with a tendency to twist and coil are ejected through the controller. That is, the fourth push rod 201 pushes the clamping block 202, so that the clamping block 202 pops out from the through holes opened on the lower die 3 and the upper die 4 respectively, and clamps the two linear segments of the large rope loop 100b between the second card wire groove 3c and the third card wire groove 3d. At this time, according to the twisting and coiling direction of the large rope loop 100b obtained by the above detection, the linear segment with an upward warping tendency that is clamped is further corrected. That is, the controller controls the first connecting pipe 203 on the clamping block 202 on this side to inflate gas into the strip cavity 202a, thereby pushing the rubbing plate 204 to pop out and insert into the strip groove 202b on another clamping block 202 in the same vertical direction. And the above-mentioned ejection actions are that the upper and lower two rubbing plates 204 in the same vertical direction pop out simultaneously. Then, during this process, the wavy parts of the two rubbing plates 204 move towards each other from one side above and the other side below respectively, rub the linear segment with an upward warping tendency that is clamped, and then drive it to rotate. After correcting it to the horizontal direction, through the cooperation of the two fourth push rods 201 on this side, the clamping actions of the two clamping blocks 202 are maintained and the two clamping blocks 202 and the thin ropes clamped by them are moved downward a small distance together, pressing down the clamped linear segment, so as to further correct it, so that after the subsequent injection molding is completed, it can be discharged together with other normally injection-molded injection pull heads 200 through the discharging system.

[0048] It should be noted that after the above correction actions are completed, since the linear segment at one end of the large rope loop 100b is rotated, the large rope loop 100b as a whole returns to a flat state, eliminating the tendency to twist. Subsequently, injection molding is carried out on the middle section of the figure-eight steel wire rope 100 and the left part of the large rope loop 100b that is constrained and fixed by the second card wire groove 3c, so that the large rope loop 100b is fixed in a flat state, thereby reducing the twisting and coiling tendency of the large rope loop 100b after injection molding, further ensuring the correction effect, and improving the appearance quality of the manufactured injection pull head 200.

[0049] Embodiment 3

[0050] As Figures 9-10As shown in the figure, the discharging system includes a fifth push rod 301, an upper convex plate 302, a blanking device 303, a second mounting plate 304, a gripper 305, a second connecting pipe 306, a dust blowing nozzle 307 and a third power assembly; each injection molding groove 3a is designed with an h movable part 3h below. The h movable part 3h is a pushing block whose upper surface fits the arc surface of the injection molding groove 3a. The pushing block is slidably connected to the lower mold 3 through four spring rods, and there is a damping between the pushing block and the lower mold 3, so that the pushing block fits tightly with the lower mold 3 to ensure the sealing of the bottom of the injection molding groove 3a; the lower pressing plate of the vertical injection molding machine 2 is installed with a fifth push rod 301; the telescopic part of the fifth push rod 301 is fixedly connected with an upper convex plate 302 for pushing the h movable part 3h to move upward, so as to jack up the figure-eight steel wire rope 100 that has completed the injection molding work; the operating table 1 and the vertical injection molding machine 2 are jointly fixedly connected with a blanking device 303; the blanking device 303 is an inclined hopper; the blanking device 303 is connected with a third power assembly; the third power assembly is connected with a second mounting plate 304; the second mounting plate 304 is installed with grippers 305 that match the number of injection molding grooves 3a, and the grippers 305 are made of high-temperature resistant flexible rubber materials; the grippers 305 are electric two-finger grippers; the second mounting plate 304 is fixedly connected with a second connecting pipe 306; the second connecting pipe 306 is communicated with an external blower; the second connecting pipe 306 is communicated with a plurality of dust blowing nozzles 307; the third power assembly is used to drive the second mounting plate 304, the grippers 305, the second connecting pipe 306 and the dust blowing nozzles 307 to move in the left-right direction and the up-down direction, so that the grippers 305 are inserted into the injection molding grooves 3a from the edge to pick off the figure-eight steel wire rope 100 that has completed the injection molding work.

[0051] As Figure 9 shown, the third power assembly includes a second guide rail 311, a second moving block 312, a third mounting plate 313 and a sixth push rod 314; each side of the blanking device 303 is installed with a second guide rail 311; each of the two second guide rails 311 is slidably connected with a second moving block 312; the two second moving blocks 312 are jointly fixedly connected with a third mounting plate 313; the third mounting plate 313 is a portal frame plate; the third mounting plate 313 is installed with two sixth push rods 314, and the telescopic parts of all the sixth push rods 314 are fixedly connected with the second mounting plate 304.

[0052] The back surfaces of the gripper hands of the gripper 305 are all treated with frosting. When the gripper hands of the gripper 305 are inserted between the molded plastic and the injection molding groove 3a, the plastic particles remaining in the corners of the injection molding groove 3a can be scraped and cleaned to prevent affecting the next injection molding.

[0053] The working principle of the above-mentioned Embodiment 3 is as follows: When the present invention performs the discharging operation, first, the vertical injection molding machine 2 is controlled to drive the upper mold 4 to move upward to disengage from the lower mold 3. Then, the second moving block 312 is controlled to drive the gripper 305 to move leftward along the direction of the second guide rail 311 to above the lower mold 3. Subsequently, the fifth push rod 301 is controlled to push the upper convex plate 302 upward, thereby pushing the h moving part 3h upward to slightly lift the plastic part 200a upward, creating a gap between it and the edge of the injection molding groove 3a. Then, the sixth push rod 314 is controlled to drive the gripper 305 to descend. After the left and right ends of the injection molding groove 3a are respectively inserted along the edge between it and the plastic part 200a, the injection molding pull head 200 is clamped. And during this process, the two jaws of the gripper 305 will deform to adapt to and adhere to the arc surface of the injection molding groove 3a, move downward along the arc from both sides respectively, and converge at the bottom of the injection molding groove 3a. Thus, during this process, the injection molding pull head 200 is peeled off from the injection molding groove 3a, and the edges of both ends of the injection molding groove 3a are wiped by the back of the jaw of the gripper 305 to clean the plastic particles falling off the injection molding pull head 200. Subsequently, the telescopic part of the sixth push rod 314 is controlled to drive the gripper 305 to move upward. After the gripper 305 disengages from the injection molding groove 3a, it resumes its shape. Then, the gripper 305 is controlled to clamp the plastic part 200a. When the gripper 305 clamps the injection molding pull head 200 and moves above the lower mold 3, the sixth push rod 314 is controlled to stop driving the gripper 305 to move. Then, the dust blowing nozzle 307 is controlled to continuously spray gas for a period of time to clean the figure-eight steel wire rope 100 and the injection molding groove 3a. Then, the second moving block 312 is controlled to move along the direction of the second guide rail 311 to drive the gripper 305 and the injection molding pull head 200 to move rightward above the blanking device 303. When the gripper 305 is controlled to release the injection molding pull head 200, the injection molding pull head 200 falls on the blanking device 303 and slides along it for collection, thereby completing the discharging operation of the injection molding pull head 200.
