[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] like Figures 1 to 4As shown, a specific embodiment of the present invention discloses a mold for producing street code clamps, including an upper mold 100 and a lower mold 200; a push assembly 300 is installed at the lower mold 200, and the push assembly 300 includes a push piece 310 and a spring 320. The push piece 310 is arranged corresponding to the molding cavity 210 of the lower mold, and the spring 320 provides the push piece 310 with a thrust to move toward the molding cavity 210, so that the push piece can extend to the molding cavity and push the formed workpiece away from the molding cavity; a pressing piece 400 is installed at the upper mold 100, and the pressing piece 400 is in sliding engagement with the pushing piece 310. The downward-moving pressing piece provides the pushing piece with the force of the compression spring to make the pushing piece separate from the molding cavity.

[0027] Among them, the lower die is provided with a feed port for the workpiece raw material to enter, which also limits the position of the workpiece raw material, so that it can accurately correspond to the forming cavity; and the upper die is provided with a corresponding cut-off portion, which completes the press forming and cuts off during the downward pressing process, so that the formed workpiece is separated from the raw material; It should be noted that the above structures are common in the clamp continuous forming die, and the details are not repeated here;

[0028] The above-mentioned mold for producing a street code clamp is used in the process of use. Figure 1 As shown in the figure, the pressing piece moves with the downward pressure of the upper die, pushing the push piece out of the forming cavity without affecting the extrusion forming of the workpiece; when the workpiece is formed, as shown in the figure, Figure 2 、 Figure 3 As shown, the pressing piece moves upward with the upper die, releasing the workpiece, and the pressing piece also releases the push on the push piece. The push piece then moves toward the molding cavity under the elastic force of the spring, pushing the workpiece in the molding cavity to the outside, thereby realizing automatic unloading and improving efficiency. In addition, this design uses the movement of the upper die as the basis for driving, without the need for additional electric drive components, which can reduce power consumption and reduce equipment and production costs.

[0029] Further, if Figure 5 As shown, a recessed area is provided in the middle of the lower mold 200, and a partition 220 is provided in the recessed area to separate the molding cavity 210 and the accommodating cavity 230. A first notch 240 is provided on the partition 220 for connecting the molding cavity and the accommodating cavity; the molding cavity is open on one side away from the accommodating cavity for unloading the molded workpiece; the ejection assembly 300 is installed in the accommodating cavity 230, and the pusher enters and exits the molding cavity through the first notch; by setting the accommodating cavity, space is provided for the ejection assembly to be installed, which is distinguished from the molding cavity to avoid affecting the processing of the workpiece; it also facilitates the design and layout of the overall structure, making the overall structure more compact.

[0030] Furthermore, the accommodating cavity 230 is open on one side away from the forming cavity 210, and a stopper 500 is installed on the outer side of the open opening. A second notch 510 is provided on the stopper 500 corresponding to the first notch 240, and the shape of the second notch is the same as that of the first notch. This makes the top and ends of the accommodating cavity open, which facilitates the disassembly and assembly of the internal push assembly.

[0031] like Figures 5 to 7 As shown, the push member 310 includes a push plate 311 and a push block 312 fixedly arranged on the top surface of one end of the push plate 311; baffles 313 are fixedly provided on both sides of the push block 312, and the baffles 313 are located in the accommodating cavity 230; a guide rod 520 is fixedly provided on the wall of the baffle 500 close to the accommodating cavity, and a guide hole 314 is correspondingly provided on the baffle 313, and the baffle 313 slides along the guide rod 520 through the guide hole 314; a spring 320 is sleeved on the guide rod 520, and the spring 320 is located between the baffle 313 and the baffle 500, providing the baffle with an elastic force toward the molding cavity; this structural design can effectively limit the movement of the push member, so that it slides along the guide rod, so that it can accurately pass through the first notch into and out of the molding cavity, and achieve the required pushing of the workpiece;

[0032] A first beveled surface 315 is provided on the top of the push block 312 on the side close to the forming cavity, and a second beveled surface 410 is provided on the bottom of the pressure piece 400 on the side away from the forming cavity. The second beveled surface 410 is slidably engaged with the first beveled surface 315. The downward-moving pressure piece pushes the push block toward the stop block, overcomes the elastic force of the spring, and retracts the push plate into the accommodating cavity; the longitudinal force is converted into lateral force through the two connected bevels, so that the required lateral pushing action can be performed on the push block, and the spring is squeezed to make the push plate separate from the forming cavity.

[0033] Furthermore, the pressing piece includes a support plate and an L-shaped pressing block fixedly arranged on one side of the support plate; the support plate is fixedly installed on the wall surface of the upper mold close to the accommodating cavity by bolts, and the side of the pressing block away from the support plate is bent downward, and the second bevel surface is arranged on the bottom side wall of the pressing block; the above structure can make the pressing piece deviate outward, which is convenient for the design and layout of the pushing component below, thereby achieving the effect of linkage cooperation; and it adopts a detachable structure, which is convenient for processing and production, and also convenient for assembly and use.

[0034] Further, if Figure 5 、 Figure 6As shown, a guide slot 250 is fixedly provided on the side of the first notch 240 away from the forming cavity. The shape of the guide slot is adapted to the shape of the push block, and the push block 312 is slidably clamped in the guide slot 250; a first slide slot 260 is formed between the outer walls on both sides of the guide slot 250 and the side walls of the accommodating cavity 230, and the bottom shape of the baffle 313 is adapted to the shape of the first slide slot 260, and the baffle 313 slides along the first slide slot 260; the movement of the push piece can be further guided and limited so that it can only move in a specific direction, which can effectively prevent the push piece from detaching from the top.

[0035] Further, if Figure 6 、 Figure 7 As shown, the push block 312 is provided with a second slide groove 316 arranged vertically, and the two sides of the second slide groove pass through the first bevel surface and the other side wall of the push block, and the top of the second slide groove passes through the top surface of the push block; a slider 420 is correspondingly provided on the second bevel surface 410, and the slider 420 slides with the second slide groove 316; the connection and guidance between the push block and the pressure piece are strengthened and extended by the cooperation of the slider and the second slide groove; and, by regulating the external driving structure, the upward movement stroke of the upper mold is limited, which does not affect the feeding, maintains the cooperation between the first bevel surface and the second bevel surface, and maintains the cooperation between the slider and the second slide groove. When the defective pressure piece moves downward, it can drive the push piece to move, so that the push plate is separated from the molding cavity.

[0036] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
