[0022] Refer to Figures 1 to 4, in this embodiment, a hydraulic press unloading jig is provided. The hydraulic press unloading jig includes an upper plate 1, which is fixedly connected to an external hydraulic press platen. A guide post 4 is fixedly connected to the lower end of the upper plate 1, and a bushing 2 is fixedly connected to the middle of the upper plate 1. A positioning table 3 is provided on the lower side of the guide post 4, and the guide post 4 is inserted and matched with the positioning table 3. A fixed frame 7 is fixedly connected to the side of the positioning table 3, and a clamping jaw 8 is installed inside the fixed frame 7. First cutting tools 11 are symmetrically fixedly connected to the clamping jaw 8. A first product 9 is placed on the positioning table 3, and a second product 12 is placed on the fixed frame 7. The first product 9 is a plastic disc assembled with a stainless steel fitting, and the second product 12 is the stainless steel fitting removed from the plastic disc. When the first product 9 is placed on the positioning table 3, the stainless steel fitting is inserted into the bottom of the plastic disc. A plastic post 91 is provided on the top of the plastic disc. The plastic post 91 is hollow, and a jack 911 is formed at the top of the plastic post 91. The stainless steel fitting is partially inserted into the plastic post 91.

[0023] Refer to Figure 1 , a guiding head 5 is fixedly connected to the lower end of the guide post 4. When inserting the guide post 4 into the positioning table 3, the guiding head 5 is used to guide the guide post 4 into the positioning table 3.

[0024] Refer to Figure 1 , a collecting box 6 is placed inside the positioning table 3. The collecting box 6 is used to collect the materials dropped from the first product 9.

[0025] Refer to Figure 1 and Figure 2 , the bushing 2 includes a bushing body 21 and a pressing needle 23. The bushing body 21 is fixedly connected to the upper plate 1, and a first blade avoidance groove 22 is formed on the bushing body 21. The upper plate 1 can descend in the vertical direction and drive the bushing 2 to move towards the positioning table 3. During the descent of the bushing 2, the bushing body 21 is sleeved on the outer periphery of the plastic post 91, and the pressing needle 23 is inserted into the plastic post 91 through the jack 911. During the continuous descent of the bushing 2, the pressing needle 23 can push the stainless steel fitting out of the plastic post 91 and out of the plastic disc. The pushed-out stainless steel fitting can fall into the collecting box 6.

[0026] In addition, refer to Figure 1 and Figure 3 , the positioning table 3 includes a carrier 31, a carrier table 33 and a second cutting tool 32. The guide post 4 is inserted and matched with the carrier table 33, and the first product 9 is clamped and matched with the carrier 31. The second cutting tool 32 is fixedly connected inside the carrier 31. The carrier table 33 is used to guide the guide post 4 to descend, so that the bushing 2 presses towards the center of the carrier 31.

[0027] Based on the above, the second tool 32 can cut the part of the plastic located on the outer periphery of the stainless-steel fitting during the process of the bushing 2 descending with the upper plate 1, thereby facilitating the push pin 23 to push the stainless-steel fitting out from the plastic disc. During the process of the bushing 2 descending, the second tool 32 can extend into the first blade avoidance groove 22, that is, the bushing body 21 can avoid the second tool 32 through the first blade avoidance groove 22.

[0029] It should be noted that a clamping groove 121 is provided on the stainless-steel fitting, and part of the plastic disc is clamped in the clamping groove 121. Moreover, during the process of the push pin 23 pushing the stainless-steel fitting out of the plastic column 91, due to the large thrust, the part of the plastic disc clamped in the clamping groove 121 will break from the main body part of the plastic disc during the process of the push pin 23 pushing the stainless-steel fitting out of the plastic column 91 and fall into the collection bin 6 together with the stainless-steel fitting. That is, waste plastic will remain in the clamping groove 121 of the stainless-steel fitting removed from the plastic disc. Therefore, the hydraulic press unloading jig in this embodiment is also provided with a fixing frame 7 and a structure installed on the fixing frame 7 to remove the waste plastic remaining in the clamping groove 121 subsequently.

[0030] Specifically, based on the above, the collar 10 is used to keep the second product 12 in a standing state, the two claw parts of the claw 8 move relatively, and drive the two blades of the first tool 11 to move relatively. Two second blade avoidance grooves 101 are provided on the collar 10, and the two blades of the first tool 11 can respectively pass through the two second blade avoidance grooves 101 and extend into the clamping groove 121 to cut the waste plastic remaining in the clamping groove 121. During the cutting process, the waste plastic will open outward, so that the two cut semi-circular ring-shaped parts can fall out of the clamping groove 121. After that, the stainless-steel fitting can be used when manufacturing other products.

[0031] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto.
