[0002] The stamping ejector mechanism for automotive metal parts is a device specifically used to eject or remove formed metal parts from the die during the stamping process. Stamping is a processing technology that applies pressure to metal sheets through a die to cause them to undergo plastic deformation, thereby obtaining parts of the desired shape and size. During the stamping process, the metal sheet is placed between the dies, and then pressure is applied by a press to make it fit with the die and form the desired shape. When the stamping is completed, the formed parts need to be removed from the die, and this is when an ejector mechanism is needed.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a stamping and ejecting mechanism for automobile metal parts, comprising a lower die mechanism 1, the top of which is fixedly connected to an upper die mechanism 2;

[0026] The lower mold mechanism 1 includes a bottom plate 101, a first slide rail 102 is fixedly installed on the top of the bottom plate 101, and two sliders 103 are slidably sleeved on the outer wall of the first slide rail 102, a trapezoidal block 104 is fixedly connected between the tops of the two sliders 103, a push-out cylinder 105 is fixedly connected to one side of the outer wall of the trapezoidal block 104, and a roller group 106 is movably contacted on the top of the trapezoidal block 104, four limit rods 107 are fixedly installed on the top of the bottom plate 101, and the outer walls of the four limit rods 107 are movably sleeved with reset springs 108, and a lifting plate 109 is movably sleeved between the outer walls of the four limit rods 107, and the roller group 1 The top of 06 is fixedly connected to the bottom of the lifting plate 109, the top of the lifting plate 109 is fixedly connected with multiple groups of fixed rods 110, the tops of the multiple groups of fixed rods 110 are fixedly connected with lifting springs 111, the inner walls of the multiple groups of fixed rods 110 are threadedly connected with ejection screws 112, the tops of the multiple groups of ejection screws 112 are provided with rotating grooves 113, the tops of the four limiting rods 107 are fixedly connected with a lower mold 114, the top of the lower mold 114 is provided with a molding groove 115, the bottom of the inner wall of the molding groove 115 is provided with multiple groups of ejection grooves 116, and the top of the lower mold 114 is fixedly installed with two guide columns 117.

[0027] The effect achieved by the entire embodiment 1 is that after the parts are stamped and formed inside the forming groove 115, the staff will start the ejection cylinder 105 through the control system, and the telescopic end of the ejection cylinder 105 will push the trapezoidal block 104 to move to the left. The inclined design of the trapezoidal block 104 enables its top roller group 106 to rise smoothly along the inclined surface, thereby driving the lifting plate 109 to move upward, and the lifting plate 109 drives the multiple groups of ejection screws 112 on its top to rise synchronously, thereby smoothly realizing the ejection operation of the formed parts. The inclined structure of the trapezoidal block 104 makes the rising action of the lifting plate 109 relatively smooth, thereby effectively preventing the deformation or damage of the parts caused by the excessively fast ejection speed. At the same time, the outer walls of the four limit rods 107 are movably sleeved with return springs 108, and the tops of the multiple groups of fixing rods 110 are fixedly connected with ejection screws 112. The lifting spring 111, four return springs 108 and multiple groups of lifting springs 111 significantly reduce the impact force during ejection, further protecting the parts from deformation caused by instantaneous impact. When it is necessary to process irregularly shaped automotive metal parts, a flat-blade screwdriver can be easily inserted into the rotating groove 113 at the top of the ejection screw 112 according to the specific shape of the part in the forming groove 115, so as to flexibly rotate the ejection screw 112. Since the outer walls of the multiple groups of ejection screws 112 are all threadedly connected with the fixing rod 110, the ejection screw 112 can be rotated to accurately adjust its extension length, so that the multiple groups of ejection screws 112 can correspond to different parts of the parts respectively, ensuring that the ejection process is more in line with the actual shape of the parts, making the ejection force evenly distributed, thereby effectively avoiding deformation and significantly improving the ejection accuracy and part quality.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the upper mold mechanism 2 includes a fixed frame 201, a punching cylinder 202 is fixedly installed on the bottom of the fixed frame 201, the telescopic end of the punching cylinder 202 is fixedly connected to the upper mold 203, a punching head 204 is fixedly installed on the bottom of the upper mold 203, two guide rods 205 are fixedly installed on the bottom of the upper mold 203, two second slide rails 206 are fixedly installed on the inner surface wall of the fixed frame 201, and the top of the base plate 101 is fixedly connected to the bottom of the fixed frame 201.

[0029] The effect achieved by the entire embodiment 2 is that when metal parts need to be stamped, the staff starts the stamping cylinder 202 through the control system. The telescopic end of the stamping cylinder 202 drives the upper die 203 to move downward smoothly and accurately, and the upper die 203 further drives the punch head 204 to move downward, thereby realizing the stamping forming of the metal sheet. Two second slide rails 206 are fixedly installed through the inner surface wall of the fixed frame 201, and the outer surface wall of the two second slide rails 206 is movably sleeved with the upper die 203, so that the upper die 203 can slide smoothly along the two second slide rails 206 during the stamping process, reducing the possibility of deviation and vibration, thereby ensuring the accuracy of stamping and the quality of parts, and two guide columns 117 are fixedly installed on the top of the lower die 114, and two guide rods 205 are fixedly installed on the top of the upper die 203. The two guide columns 117 and the two guide rods 205 play a role of guiding and positioning, further enhancing the stability and accuracy of the stamping process.

[0030] Working principle: When stamping of automotive metal parts is required, the staff will first flexibly adjust the position of the ejector screw 112 according to the specific shape of the parts in the forming groove 115, and easily insert the rotating groove 113 at the top of the ejector screw 112 through a flat screwdriver. The staff can easily rotate the ejector screw 112 to adjust its extension length. At this time, multiple groups of ejector screws 112 can correspond to different parts of the parts, ensuring that the ejection process is more in line with the actual shape of the parts, thereby effectively avoiding deformation. When stamping of metal parts is required, the control system starts the stamping cylinder 202, and then the stamping cylinder The telescopic end of 202 starts to work, steadily and powerfully pushing the upper die 203 downward. In the process of the upper die 203 moving downward, it further drives the punch head 204 to accurately align downward with the metal sheet, thereby realizing the stamping operation of the metal sheet, and the two guide rods 205 and the two guide columns 117 are closely matched to play a precise guiding and positioning role, effectively preventing the dislocation and deviation of the die during the stamping process. When the parts are stamped and formed inside the forming groove 115, the staff starts the ejection cylinder 105 through the control system, and the telescopic end of the ejection cylinder 105 quickly and steadily pushes the trapezoidal block 10 4 moves to the left, the trapezoidal block 104 drives the inner roller of the roller group 106 to roll upward along its inclined surface, thereby driving the lifting plate 109 to rise steadily. In this process, the lifting plate 109 carries multiple groups of ejection screws 112 to rise synchronously, and accurately and powerfully ejects the molded parts. The inclined surface of the trapezoidal block 104 effectively controls the rising speed of the lifting plate 109, realizing slow and stable ejection, thereby avoiding deformation or damage of parts caused by excessive speed. In the ejection process, as the lifting plate 109 gradually rises, it will gradually squeeze the four return springs 108, and at the same time, the multiple groups of fixing rods 110 will also be correspondingly The four return springs 108 and the multiple groups of lift springs 111 can effectively absorb and disperse the impact force and play a buffering role, thereby preventing the parts from being damaged or deformed due to the instantaneous impact. Once the parts are successfully ejected from the forming groove 115, the telescopic end of the ejection cylinder 105 will begin to contract. At this time, the four return springs 108 and the multiple groups of lift springs 111 will use their elastic potential energy to quickly reset. This reset process not only enables the lifting plate 109 to quickly return to the initial position to prepare for the next ejection operation, but also ensures the stability and reliability of the entire ejection mechanism.
