Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example

[0021] like Figure 1 , 2As shown, in this embodiment, a stamping device that is convenient for demoulding is mainly disclosed, including a base 1 and a bracket 2 fixed above the base 1, a telescopic cylinder 3 is installed on the bracket 2, a lower mold 4 is movably placed on the base 1, a movable end of the telescopic cylinder 3 is connected to a guide rod 5 and an upper mold 6 that cooperates with the lower mold 4, the guide rod 5 is vertically movably connected to the base 1, the guide rod 5 and the outer edge of the lower mold 4 are wedge-shapedly matched to press against the lower mold 4, and an elastic component 7 for separating the lower mold 4 is provided between the lower molds 4; specifically, the telescopic cylinder 3 is installed and fixed above the lower mold 4 through the bracket 2, and the upper mold 6 is driven by the telescopic cylinder 3 to press down and cooperate with the lower mold 4 to realize the molding production of parts, and the movable end of the telescopic cylinder 3 is connected to the guide rod 5 and the upper mold 6 through the connecting plate 30; in the initial state, the upper mold 6 and the lower mold The mold 4 is separated into upper and lower parts, and the lower mold 4 is in a separated state under the action of the elastic component 7. The material to be molded is placed on the lower mold 4, and the telescopic cylinder 3 is driven to press down. Since the guide rod 5 and the outer edge of the lower mold 4 are wedge-shaped, the lower mold 4 is first pushed by the guide rod 5 to gradually compress the elastic component 7 to achieve closing. After the lower mold 4 is merged, the elastic component 7 is hidden in the lower mold 4, and the guide rod 5 just presses against the outer edge of the lower mold 4. As the telescopic rod is further pressed downward, the upper mold 6 cooperates with the lower mold 4 to mold the material. After molding, the telescopic cylinder 3 is controlled to lift up, driving the guide rod 5 to rise, and then the lower mold 4 is separated under the action of the resetting elastic force of the elastic component 7, thereby avoiding the material being stuck in the lower mold 4 during demoulding, effectively improving the convenience and production efficiency of demoulding.

[0022] Furthermore, in the specific implementation, if Figure 3 As shown, the elastic component 7 provided in the embodiment of the utility model includes a positioning block 71 and springs 72 respectively connected to the two sides of the positioning block 71. The positioning block 71 is clamped and limited between the lower molds 4, and the springs 72 on both sides are respectively limited in the adjacent lower molds 4; specifically, a horizontal coaxial stepped hole is opened on the docking surface of the lower mold 4, the outer side is a large diameter end, and the inner side is a small diameter end. The positioning block 71 is clamped in the large diameter end of the adjacent docking lower mold 4, and the springs 72 fixed on both sides of the positioning block 71 are respectively limited in the small diameter end of the adjacent lower mold 4, thereby avoiding the situation that only springs 72 are set between the lower molds 4, which is easy to shake during docking and causes docking misalignment, thereby ensuring the accuracy of docking between the lower molds 4.

[0023] Furthermore, in a specific implementation, when the upper mold 6 and the lower mold 4 provided in the embodiment of the utility model are in place, the guide rod 5 moves downward and presses against the base 1. It should be noted that when the upper mold 6 and the lower mold 4 are in place, there is a gap between the upper mold 6 and the lower mold 4 with the required processing thickness of the material. At this time, the guide rod 5 moves downward and just presses against the base 1, preventing the telescopic cylinder 3 from further pressing down, thereby ensuring the stability of the material processing thickness.

[0024] Furthermore, in a specific implementation, the above-mentioned lower mold 4 provided in the embodiment of the utility model is evenly divided into multiple parts, and each part of the lower mold 4 is at least correspondingly provided with a guide rod 5. Specifically, the guide rod 5 should act on the midpoint position or the midpoint symmetrical position of the outer edge of the lower mold 4 to ensure the stability of the force.

[0025] Furthermore, in a specific implementation, a limit block 51 engaged with the base 1 is provided at the bottom end of the guide rod 5 provided in the embodiment of the utility model to prevent the telescopic cylinder 3 from being excessively lifted up.

[0026] Furthermore, in a specific implementation, the guide rod 5 provided in the embodiment of the utility model includes, from top to bottom, a large diameter section 52 and a small diameter section 53 of a wedge-shaped transition; specifically, when the telescopic cylinder 3 is pressed downward and the lower mold 4 is brought together, the lower mold 4 is pressed tightly against the large diameter section 52 of the guide rod 5; when the telescopic cylinder 3 is lifted and the lower mold 4 is separated, the lower mold 4 is pressed tightly against the small diameter section 53 of the guide rod 5.

[0027] Furthermore, in a specific implementation, a plurality of elastic components 7 are evenly arranged between the above-mentioned lower molds 4 provided in the embodiment of the utility model to ensure that the lower molds 4 can be stably and effectively separated during demoulding.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
