[0002] An extrusion forming die is required when processing the workpiece, and the workpiece is extruded through the extrusion forming die.

[0003] When in use, the existing extrusion molding die generally clamps the workpiece on the die through a positioning mechanism, thereby positioning the workpiece for extrusion. However, the existing positioning mechanism cannot be linked with the machine tool lifting and lowering of the extrusion molding die, and the workpiece needs to be positioned separately. The positioning steps of the existing positioning mechanism are cumbersome and inefficient, which is not conducive to the continuous extrusion processing of the equipment. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] (1) The utility model adds an elastic member and a positioning pin, and the elastic force of the elastic member causes the positioning pin to abut against the workpiece between the upper molds first, thereby performing linkage positioning by the positioning pin before the workpiece is stamped, thereby reducing the difficulty of positioning the workpiece by the equipment.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] refer to Figure 1-2 As shown, the utility model provides a positioning device that can be linked with a machine tool during product molding, including: an upper mold 1 that is lifted and installed above a lower mold 6, a stamping area for stamping a workpiece is formed on the top of the lower mold 6, and an elastic member 14 and a positioning pin 2 are inlaid in sequence at the bottom of the upper mold 1 from top to bottom, the bottom end of the positioning pin 2 extends to the bottom of the upper mold 1, and the elastic member 14 is used to elastically abut the positioning pin 2 against the workpiece.

[0023] As mentioned above, when using the upper mold 1, lower mold 6, elastic member 14 and positioning pin 2 provided by the utility model, the elastic member 14 and the positioning pin 2 are embedded and installed on the bottom of the upper mold 1. When the upper mold 1 descends, the bottom end of the positioning pin 2 first abuts against the workpiece. When the upper mold 1 continues to descend, the elastic member 14 is compressed, and the elastic force generated abuts against the workpiece through the positioning pin 2, thereby producing a linkage positioning of the workpiece. After the upper mold 1 is away from the lower mold 6, the positioning effect of the positioning pin 2 on the workpiece disappears directly, and there is no need to perform additional operation on the positioning pin 2. The existing upper mold 1 is generally raised and lowered by a liftable support frame and a hydraulic cylinder, which are not drawn in the figure.

[0024] Further, in order to facilitate the concealed installation of the positioning pin 2 and the elastic member 14 in the upper mold 1, refer to Figure 4 As shown, the bottom of the upper mold 1 is provided with a mounting hole 15, the top of the positioning pin 2 extends into the mounting hole 15, and the elastic member 14 is installed between the mounting hole 15 and the top of the positioning pin 2, and the elastic member 14 is C-shaped. When the upper mold 1 falls onto the workpiece, the elastic member 14 and the positioning pin 2 are both pressed into the mounting hole 15, and at this time, the positioning pin 2 applies the force generated by the compressed elastic member 14 to the workpiece, thereby pressing and positioning the workpiece.

[0025] Further, in order to prevent the positioning pin 2 from causing damage to the workpiece and preventing the workpiece from displacement, refer to Figure 1-2 As shown, a rubber pad 3 is also provided at the bottom of the locating pin 2, and the rubber pad 3 abuts against the workpiece. A rubber pad 3 is installed at the bottom of the locating pin 2 to protect the workpiece, so as to prevent the locating pin 2 from causing pressure damage to the workpiece and prevent the locating pin 2 from being displaced when abutting against the workpiece.

[0026] In the present utility model, combined with Figure 1-2As shown, in the present embodiment, unloading mechanisms are installed on both symmetrical sides of the upper mold 1 in the longitudinal direction, and the unloading mechanisms are used to push the workpiece downward from the upper mold 1 .

[0027] Combination Figure 1-2 As shown, the unloading mechanism includes a mounting seat 9 and a push block 7 installed in sequence from top to bottom, one end of the mounting seat 9 is welded to the upper mold 1, a lifting rod 10 penetrating the mounting seat 9 is provided on the top of the push block 7, and a first spring 8 sleeved on the lifting rod 10 is provided between the mounting seat 9 and the push block 7.

[0028] As mentioned above, when using the unloading mechanism provided by the utility model, when the upper mold 1 drives the workpiece to be stamped and formed in the stamping chamber 11 on the lower mold 6, the two ends of the workpiece are bent upward. At this time, the bent workpiece drives the push block 7 to push upward, thereby compressing the first spring 8 on the lifting rod 10. When the upper mold 1 is separated from the lower mold 6, the elastic force of the first spring 8 is greater than the friction force between the workpiece and the upper mold 1. At this time, the elastic force of the first spring 8 is released, thereby driving the lifting rod 10 to move downward on the mounting seat 9, and then the workpiece wrapped on the upper mold 1 is unloaded downward through the push block 7 to prevent the workpiece from being formed and wrapped on the upper mold 1.

[0029] In the present utility model, combined with Figure 3 As shown, a stamping bin 11 is provided at the top of the lower die 6 of the present embodiment, a stamping area is formed in the stamping bin 11, and an ejection mechanism is also installed at the bottom of the stamping bin 11, and the ejection mechanism is used to eject the workpiece in the stamping bin 11 outwards.

[0030] Combination Figure 3 As shown, the ejection mechanism includes a floating platform 4 and a second spring 12. A lifting groove 13 is provided at the bottom of the stamping bin 11. A lifting block 5 movably inserted into the lifting groove 13 is provided at the bottom end of the floating platform 4. The second spring 12 is longitudinally installed in the lifting groove 13, and the top end of the second spring 12 abuts against the bottom end of the lifting block 5.

[0031] As mentioned above, when using the ejection mechanism provided by the utility model, the floating platform 4 in the ejection mechanism is installed in the stamping bin 11 by means of the lifting groove 13, the lifting block 5 and the second spring 12. When the workpiece is punched into the stamping bin 11, the floating platform 4 is forced to descend, and at the same time, the lifting block 5 presses and compresses the second spring 12 in the lifting groove 13. When the upper mold 1 is separated from the lower mold 6, the elastic force of the second spring 12 is released, thereby driving the lifting block 5 to be ejected outward from the lifting groove 13, and then driving the floating platform 4 to eject the workpiece in the stamping bin 11 outward, so as to facilitate the unloading of the workpiece.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
