[0028] 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.

[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: a mold for manufacturing automobile parts, including an operating table 1, a movable seat 2 is slidably connected to the inner wall of the top of the operating table 1, and the movable seat 2 mainly connects and supports the lower mold 9. The outer wall of the movable seat 2 is fixedly connected to a handle 4, and the entire movable seat 2 can be moved laterally by the handle 4. The top of the handle 4 is elastically connected to a connecting pipe 6 through a reset spring 5, and a limiting mechanism is arranged at the bottom end of the connecting pipe 6. The top of the movable seat 2 is detachably mounted with a lower mold 9, and the lower mold 9 is fixed to the top of the movable seat 2 by an existing installation method. A hydraulic rod 10 is arranged on the inner wall of the bottom end of the operating table 1. The hydraulic rod 10 is the main component of the existing stamping mold for manufacturing some automobile parts. The upper mold 11 and the lower mold 9 can be stamped by the hydraulic rod 10. It is the existing technology and will not be described in detail here. The movable end of the hydraulic rod 10 is detachably mounted with the upper mold 11.

[0030] Reference Figure 1-Figure 3 The inner wall at the top of the operating table 1 is fixedly connected with a fixed block 12, and the fixed block 12 is an inclined surface, so that the extrusion rod 13 can move upward along the inclined surface. The inner wall of the movable seat 2 passes through and is slidably connected with the extrusion rod 13, and the bottom end of the extrusion rod 13 is a round surface, so that the extrusion rod 13 can be better squeezed by the fixed block 12. The top of the extrusion rod 13 is fixedly connected with a support plate 14, and the top of the support plate 14 is fixedly connected with an ejector pin 3, and the processing material can be ejected through the ejector pin 3 for subsequent workers to take.

[0031] The support plate 14 is slidably connected to the inner wall of the movable seat 2, the ejector pin 3 penetrates and is slidably connected to the inner wall of the movable seat 2, and the movable seat 2 is respectively provided with slots corresponding to the support plate 14 and the ejector pin 3, so that the support plate 14 and the ejector pin 3 can move vertically, the ejector pin 3 penetrates and is plugged into the inner wall of the lower mold 9, and the lower mold 9 is provided with a slot corresponding to the ejector pin 3, and the bottom end of the extrusion rod 13 contacts the surface of the fixed block 12.

[0032] Reference Figure 1-Figure 3 The top of the handle 4 is fixedly connected to one end of the return spring 5. When the connecting tube 6 moves upward, the return spring 5 will be stretched. When resetting, the elastic force of the return spring 5 is used to return the connecting tube 6. The other end of the return spring 5 is fixedly connected to the inner side wall of the connecting tube 6. The connecting tube 6 passes through and is slidably connected to the inner wall of the handle 4. The limiting mechanism includes an L frame 7. The L frame 7 mainly connects the connecting tube 6 and the limiting tube 8. The L frame 7 is fixedly connected to the bottom end of the connecting tube 6. The bottom end of the L frame 7 is fixedly connected to the limiting tube 8. The L frame 7 is slidably connected to the inner wall of the movable seat 2. The movable seat 2 is provided with slots corresponding to the limiting tube 8 and the L frame 7, so that the limiting tube 8 and the L frame 7 can move vertically along the slots of the movable seat 2. The limiting tube 8 passes through and is slidably connected to the inner wall of the movable seat 2. The limiting tube 8 is plugged into the inner wall of the top of the operating table 1, such as Figure 2 As shown, a slot is provided at the sliding part of the movable seat 2 on the operating table 1 , so that the limiting tube 8 can be plugged into the slot to limit the entire movable seat 2 .

[0033] Working principle: First, when you need to place the auto parts workpiece, just hold the handle 4 and let your fingers pass through the handle 4, and use your fingers to push the L frame 7 upward to move the connecting tube 6 and the limiting tube 8 upward. At this time, the reset spring 5 is in a stretched state, so that the limiting tube 8 is separated from the notch on the top inner wall of the operating table 1. Then move the handle 4 to move the reset spring 5 and the connecting tube 6 to the left, and release the L frame 7 to use the reverse elastic force of the reset spring 5 to reset the connecting tube 6, the L frame 7 and the limiting tube 8, so that the limiting tube 8 contacts the top inner wall of the operating table 1. Since the limiting tube 8 does not overlap with the notch on the inner wall of the top end of the operating table 1, the reset spring 5 will continue to be in a stretched state, and then the handle 4 will continue to be pulled to move the reset spring 5 and the connecting tube 6 to the left, so that the extrusion rod 13 will move upward along the inclined surface of the fixed block 12 with the support plate 14 and the ejector 3. When the handle 4 moves to the leftmost end, the extrusion rod 13 is at the top of the fixed block 12 and the ejector 3 completely ejects the processed workpiece, so that the staff can replace the workpiece by hand to reduce the danger during processing.

[0034] After replacing the workpiece, just push the handle 4 to the right to move the movable seat 2 and the lower mold 9 to the right. At this time, the extrusion rod 13 will slide along the inclined surface of the fixed block 12, and reset downward by the self-gravity of the workpiece, the extrusion rod 13, the support plate 14 and the ejector 3. When the movable seat 2 moves to the rightmost end of the operating table 1, the limiting tube 8 will coincide with the notch on the inner wall of the top end of the operating table 1, and the reverse elastic force of the reset spring 5 will be used to move the connecting tube 6, the L frame 7 and the limiting tube 8 downward and reset, so that the limiting tube 8 and the notch on the inner wall of the top end of the operating table 1 are plugged in to limit the entire movable seat 2. This operation can be repeated during subsequent continuous processing.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
