DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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] For example, see Figure 1-4 The present invention provides a technical solution: a punching device for mold manufacturing, comprising a base 1, a mobile platform 101 is fixedly connected to the top of the base 1, a sliding seat 102 is slidably connected to the surface of the mobile platform 101, and a support assembly 11 is fixedly connected to the top of the base 1. The purpose of such a setting is to drive the punching mechanism 2 to move up and down through the sliding seat 102 on the mobile platform 101, so as to complete the punching operation; The supporting assembly 11 comprises a shell 111, the bottom of the shell 111 is fixedly connected to the base 1, the inner wall of the shell 111 is slidably connected to an annular plate 112, the inner wall of the annular plate 112 is fixedly connected to an annular plate 2 113, the bottom of the annular plate 2 113 is fixedly connected to an elastic U-shaped plate 114, one end of the elastic U-shaped plate 114 away from the annular plate 2 113 is fixedly connected to the shell 111, the bottom of the annular plate 2 113 is fixedly connected to a rotating seat 115, and the outer wall of the rotating seat 115 is fixedly connected to the outer wall of the rotating seat 115. The elastic plate 116 is connected to the rotating seat 115, and the end of the elastic plate 116 away from the rotating seat 115 is fixedly connected to the fixed head 117, and the outer wall of the fixed head 117 is fixedly connected to the pressure plate 118. The purpose of this arrangement is that after the pressure plate 118 contacts the raw material, the gravity of the raw material itself will drive the raw material plate 118 to move downward, so that the elastic plate 116 connected to the pressure plate 118 will be deformed due to the movement of the pressure plate 118, and the relative distance between the two ends of the deformed elastic plate 116 is reduced. The distance between the pressure plate 118 and the annular plate 113 is shortened, so that its own elastic potential energy increases. The increased elastic potential energy will react on the pressure plate 118 and be applied to the bottom of the raw material, thereby increasing the pressure between the raw material and the pressure plate 118, so as to improve the fixing effect. At the same time, by providing a plurality of patterns on the surface of the pressure plate 118, the raw material is prevented from rotating with the drill bit during drilling, thereby improving the drilling effect. When the raw material is placed on the component, the pressure plate 118 will first drop. When the upper surface of the pressure plate 118 and the upper surface of the annular plate 1 are on the same horizontal plane, the annular plate 112 will be driven to move downward along the inner wall of the shell 111. The downward moving annular plate 112 also moves downward with the annular plate 2 113, and then the elastic U-shaped plate 114 is driven to deform through the extrusion of the annular plate 2. The elastic U-shaped plate 114 converts the elastic force generated by the deformation into pressure, and fixes the periphery of the raw material through the clamping effect of the annular plate 112 and the placement component, thereby preventing the raw material from moving and improving the stability of the drilling.

[0021] Embodiment 2 is different from Embodiment 1 in that: Figure 5-Figure 8 As shown, the punching mechanism 2 includes a motor 201 fixedly connected to the inner wall of the sliding seat 102, the output end of the motor 201 is fixedly connected to the drill bit 202, and the bottom of the motor 201 is fixedly connected to the cleaning component 21. The purpose of this arrangement is to drive the sliding seat 102 to move through the mobile platform 101, so that the motor 201 and the drill bit 202 also move. Before the drill bit 202 contacts the raw material, the cleaning component 21 on the motor 201 will first contact the raw material, so that when the device punches the raw material, it only needs to change the height of the electric drill to complete the fixation, and there is no need to fix the raw material by rotating multiple bolts.

[0022] The cleaning component 21 includes an annular plate three 211, the top of the annular plate three 211 is fixedly connected to the motor 201, the bottom of the annular plate three 211 is fixedly connected to a connecting plate one 212, the end of the connecting plate one 212 away from the annular plate three 211 is fixedly connected to a center plate 213, the inner wall of the center plate 213 is slidably connected to a slide bar one 214, the inner wall of the slide bar one 214 is slidably connected to a slide bar two 215, the end of the slide bar two 215 away from the slide bar one 214 is fixedly connected to the annular plate three 211, the outer wall of the slide bar two 215 is sleeved with a spring 216, the purpose of setting the spring 216 is to facilitate the component to be reset under the action of the elastic force of the spring 216, and the spring 216 is provided to facilitate the component to be reset under the action of the elastic force of the spring 216. The bottom of the spring 216 is fixedly connected to the slide bar 1 214, and the end of the spring 216 away from the slide bar 1 214 is fixedly connected to the annular plate 3 211.

The side of the bottom plate 217 away from the slide bar 1 214 is fixedly connected to the connecting plate 219, and the end of the connecting plate 219 away from the bottom plate 217 is fixedly connected to the pressure plate 2110. The outer wall of the bottom plate 217 is fixedly connected to the connecting head 2111, and the outer wall of the connecting head 2111 is rotatably connected to the auxiliary component 22. When the punching operation is required, the sliding seat drives The motor 201 moves downward, and the movement of the motor 201 will drive the entire cleaning assembly 21 to move downward together. When the pressure plate 2110 contacts the raw material, the pressure plate 2110 will no longer move, while the connecting plate 1 212 and the center plate 213 will continue to move downward along the trajectory of the slide bar 1 214, and then generate linkage with the auxiliary assembly 22. During the movement of the connecting plate 1 212, the annular plate 3 211 will also be driven to move downward together, so that the slide bar 215 connected to the annular plate 3 211 shrinks into the inside of the slide bar 1 214, and at the same time, the relative distance between the annular plate 3 211 and the slide bar 1 214 becomes closer, and then the spring 216 squeezes the two. The spring 216 that has been deformed applies the elastic potential energy generated by the deformation to the pressure plate 2 through the slide bar 1 214. At this time, the pressure plate 2110 applies pressure from the top of the raw material under the pressure given by the spring 216 and the thrust formed by the downward movement of the sliding seat, and the support component applies supporting force from the bottom of the raw material. The raw material is fixed by the clamping of the two forces. At the same time, the debris generated by drilling will first be discharged through the gap between the connecting plates 219, and some debris that has not been discharged will be discharged from the gap on the outer surface of the cleaning plate 218 under the centrifugal force of the drill bit, so as to avoid the debris affecting the drilling effect and preventing the debris from remaining on the drill bit to damage the drill bit. The auxiliary component 22 includes a connecting rod 221, the outer wall of the connecting head 2111 is rotatably connected to the connecting rod 221, the end of the connecting rod 221 away from the connecting head 2111 is fixedly connected to a rotating plate 222, the outer wall of the rotating plate 222 is fixedly connected to an elastic telescopic rod 223, the end of the elastic telescopic rod 223 away from the rotating plate 222 is rotatably connected to the connecting plate 1 212, the top of the connecting rod 221 is fixedly connected to a slider 224, the outer wall of the slider 224 is slidably connected to a sliding plate 225, the inner wall of the sliding plate 225 is fixedly connected to an elastic wave plate 226, the end of the elastic wave plate 226 away from the sliding plate 225 is slidably connected to the slider 224, the end of the sliding plate 225 away from the connecting plate 1 212 is fixedly connected to an elastic plate 227, when the connecting plate 1 212 moves downward along the sliding rod 1 214, the elastic telescopic rod 223 is also driven to move downward, and the elastic telescopic rod 2 The downward movement of 23 will drive the connecting rod 1 221 to rotate outward with the bottom connection as the center of the circle. The rotated connecting rod 1 221 will make the sliding plate 225 contact the bottom and the raw material. After the sliding plate 225 contacts the bottom and the raw material, the connecting plate 1 212 will still move downward, so that the relative distance between the bottom of the sliding plate 225 and the slider 224 becomes closer, and then the elastic wave plate 226 is deformed under the squeezing of the two. The deformed elastic wave plate 226 will convert the elastic potential energy generated by the deformation into pressure applied to the bottom of the sliding plate 225 and then transferred to the surface of the raw material to enhance the fixing effect, and through the easy deformation characteristics of the elastic plate 227, the force generated when the sliding plate 225 contacts the raw material is buffered to avoid damage to the surface of the original part due to excessive pressure, and the contact area between the bottom of the auxiliary component and the raw material is increased to avoid the raw material from rotating under the rotation of the drill bit, thereby improving the punching effect.
