Description

Technical Field

[0001] The utility model relates to a forming die for an automobile handle ring. Background Art

[0002] A car door handle is a convenient tool installed on the inside of a car door for closing the door. Its purpose is to allow the driver or passenger to easily control the opening and closing of the door, providing a place for the driver or passenger to apply force. Due to cost and production convenience, most door handles on the market are plastic parts. Therefore, the manufacturing process of door handles must rely on a matching molding mold and be completed in an injection molding machine.

[0003] Since the edge of the opening of the handle ring needs to be made into a step surface opposite to the demolding method, the above-mentioned structure cannot be formed by simply using passive demolding. In order to form the above-mentioned structure, the existing handle ring molding molds all install a chimeric block in the passively shifted slider and install a cylinder on the outside of the slider to drive the chimeric block to move. However, such a structure will cause the processing steps to be more complicated, and the installation and debugging will also be more difficult, time-consuming and labor-intensive. In addition, the use of cylinders will increase the production cost, which needs further improvement. Utility Model Content

The front side of the second slider 51 is formed with a second stopper 511 facing forward, and the left side of the second stopper 511 is formed with a second side forming block 512 facing left.

[0028] It also includes two active forming modules 7 which are arranged on the left side of the fixed mold base 8 and are symmetrically distributed up and down. The active forming module 7 includes a third slider 71 movably connected to the front side of the fixed mold base 8 to have the function of tilting left and right, and a traction cylinder 72 fixed on the outer wall of the fixed mold base 8. The telescopic end of the traction cylinder 72 is parallel to the moving direction of the third slider 71 and is fixed on the third slider 71. The front side of the third slider 71 is formed with a third stop block 711 forward, and the right side of the third stop block 711 is formed with a third side forming block 712 to the right.

[0029] A first inclined surface 202 is formed at the right corner of the end of the second module 201 . Correspondingly, a second inclined surface 302 cooperating with the first inclined surface 202 is formed at the left corner of the end of the first module 301 .

[0030] A first groove 203 and a first boss 205 are formed in the middle of the first inclined surface 202, and correspondingly, a second boss 303 and a second groove 304 are formed in the middle of the second inclined surface 302, respectively. The second boss 303 cooperates with the first groove 203, and the second groove 304 cooperates with the first boss 205.

[0031] Two blocks 204 are also formed forward on the end face of the fixed mold core 2, which are symmetrically arranged on the upper and lower sides of the right edge of the first inclined surface 202. Correspondingly, a symmetrically distributed card slot 305 is opened on the upper and lower sides of the first module 301, and the two card slots 305 respectively cooperate with the two blocks 204.

[0032] A corner groove 513 is formed at the end of the second side forming block 512 .

[0033] A wedge-shaped block 713 is formed outwardly on one side of the third side forming block 712 close to the fixed mold core 2 , and a forming groove 714 is formed on the front outer wall of the wedge-shaped block 713 .

[0034] A countersunk hole 442 is formed on the end surface of the formed protrusion 441 , and a first rib groove 444 and three second rib grooves 443 are formed on the inner wall of the countersunk hole 442 . The first rib groove 444 and the three second rib grooves 443 are evenly arranged at equal angles along the circumferential direction.

[0035] Working principle:

[0036] Fix the fixed mold base 8 and drive the end plate 6 and the movable mold base 1 to move backward until the rear side of the movable mold base 1 and the front side of the fixed mold base 8 are spliced with each other. At this time, the end plate 6 and the movable mold base 1 maintain a certain distance; at this time, the first inclined surface 202 on the fixed mold core 2 and the second inclined surface 302 on the movable mold core 3 cooperate with each other and are spaced a certain distance apart, the second boss 303 and the first boss 205 extend into the first groove 203 and the second groove 304 respectively, and the two card slots 305 are inserted into the two card blocks 204 respectively.

[0037] During the movement, the movable mold base 1 will drive the first traction column 42 in each composite molding mechanism 4 to move synchronously to force each first slider 41 to move toward the fixed mold core 2, thereby causing each first side molding block 412 to extend between the first inclined surface 202 and the second inclined surface 302.

[0038] Then, the end plate 6 is driven to move forward until it contacts the movable mold base 1, thereby driving the seat block 43 in each sliding unit to move backward to force the positioning bar 44 to move tilted toward the first side forming block 412, so that the end of the forming protrusion 441 on the positioning bar 44 is attached to the corresponding side outer wall of the first side forming block 412.

[0039] During the movement, the movable mold base 1 will also drive the second traction column 52 in each passive forming module 5 to move synchronously to force each second slider 51 to move toward the fixed mold core 2, thereby allowing each second side forming block 512 to extend between the first inclined surface 202 and the second inclined surface 302.

[0040] At the same time, it is also necessary to drive the telescopic ends of the traction cylinders 72 in the two active forming modules 7 to extend outward to drive the two third sliders 71 to move toward the fixed mold core 2, so that the two third side forming blocks 712 are extended between the first inclined surface 202 and the second inclined surface 302.

[0041] Afterwards, the molten material can be passed through the runner provided in the movable mold base 1 to the space between the first inclined surface 202 and the second inclined surface 302 , and the handle ring can be formed after cooling. The above principle is the existing technology.

[0042] During demolding, first drive the end plate 6 to move away from the movable mold base 1, and then drive each positioning bar 44 to move in the opposite direction to reset. At the same time, drive the telescopic ends of the two traction cylinders 72 to retract inward to drive the two third sliders 71 to move in the opposite direction to reset. Then, the movable mold base 1 can be driven to move away from the fixed mold base 8, and then force each first slider 41 and each second slider 51 to move in the opposite direction to reset. Finally, the formed handle ring can be removed with the help of the ejection mechanism provided on the fixed mold base 8.

[0043] The present invention can easily form a step surface on the handle ring with the help of a plurality of sliding units, which is opposite to the demolding method. Moreover, the sliding unit is arranged between the movable mold base 1 and the end plate 6. There is no need to change the structure of the fixed mold base 8 and the first sliding block 41. It only needs to be processed separately on the movable mold base 1 and the end plate 6, thereby simplifying the processing steps and reducing the difficulty of installation and debugging to achieve the effect of saving time and effort. In addition, there is no need to install a cylinder specifically for driving the sliding unit, thereby reducing the production cost.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
