Description

Technical Field

[0001] This utility model relates to the field of electrical component processing technology, and in particular to a capacitor shell forming mold. Background Technology

[0002] A capacitor is an electronic component primarily used to store electrical charge and energy. It consists of an insulating medium between two conductors, which are called the capacitor's plates. When a capacitor is powered on, positive charges accumulate on the positive plate and negative charges accumulate on the negative plate, resulting in an electric field between the plates. This electric field stores the electrical energy in the capacitor. It is a widely used electrical component. Aluminum shell structure is a common capacitor shell structure. In the production process, a stretching die is generally used in conjunction with a hydraulic press to extrude the blank.

[0003] The existing capacitor shell cold extrusion process has the following drawbacks: after the punch finishes extruding the blank, the formed aluminum shell workpiece will cover the outer periphery of the punch and move out of the die core as the punch moves upward. At this time, the formed workpiece on the outer periphery of the punch needs to be removed manually before the subsequent extrusion production process can be carried out. This process involves a lot of manual operation, and the workpiece must be separated and then removed, which is cumbersome. To address this, we propose a capacitor shell forming die. Utility Model Content

[0004] The main purpose of this utility model is to provide a capacitor shell forming mold. Through the unloading mechanism set inside the machine body, the formed capacitor shell can be automatically unloaded, making it easy to take out and reducing the amount of manual operation. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A capacitor casing forming mold includes a machine body and a stripping mechanism. The stripping mechanism is provided inside the machine body and includes a lower mold base, a lower mold core, an upper mold base, a punch, a sleeve, a screw hole A, a screw, a horizontal plate, and a retaining ring. The lower mold base is installed at the bottom of the machine body, and the lower mold core is installed inside the lower mold base. The power output end of the machine body is connected to a punch corresponding to the position of the lower mold core through the upper mold base. Sleeves are fixedly connected to both sides of the top of the lower mold base, and screw holes A are vertically opened inside the sleeves. A screw is screwed to the sleeve through the screw holes A, and a horizontal plate is installed between the top ends of the screw. A retaining ring corresponding to the position of the punch is movably connected inside the horizontal plate.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the horizontal plate and the retaining ring. The adjustment mechanism includes a screw hole B, a bolt, and a connecting ring. A screw hole B is horizontally opened at both ends inside the horizontal plate. The horizontal plate is screwed to the bolt through the screw hole B. A connecting ring is provided inside the retaining ring at the end of the bolt near the retaining ring. The horizontal plate has a screw hole B inside and is connected to the retaining ring through the screw hole B and the bolt. When adjusting the mold, the bolt can be turned along the screw hole B. When the bolt is turned, it drives the connecting ring to rotate inside the retaining ring, thereby allowing the bolt to move horizontally, adjusting the spacing and position of the retaining rings so that the retaining rings fit precisely against the outer periphery of the punch, ensuring accurate material removal. This adjustment is convenient and suitable for material removal from punches of different specifications.

[0008] Furthermore, the end of the screw penetrates the interior of the horizontal plate, and an end ring is fixedly connected to the top of the screw, with the end rings respectively attached to the upper and lower sides of the surface of the horizontal plate; the end ring structure plays a connecting role between the end of the screw and the horizontal plate, connecting the horizontal plate and the screw together without affecting the screw's turning.

[0009] Furthermore, adhesive pads are bonded to opposite sides of the retaining ring surface and are attached to the punch surface; the adhesive pad structure attached to the retaining ring surface is attached to the punch surface, which can prevent the retaining ring from causing wear to the punch.

[0010] Furthermore, the horizontal plate has horizontally oriented limit holes on both sides of the screw hole B, and the surface of the retaining ring is welded with a limit rod that is inserted into the limit hole; the limit rod structure is inserted into the limit hole inside the horizontal plate to limit the retaining ring, so that it can only move horizontally and will not rotate.

[0011] Compared with the prior art, this utility model has the following advantages: An upper mold base and a lower mold base are respectively installed at the upper and lower ends of the machine body. The capacitor shell material is placed inside the lower mold core. The upper mold base drives the punch to move down and insert into the lower mold core, cold-extrudes the blank to form it. Sleeves and screw structures are provided on both sides of the lower mold base. During mold adjustment, the screws on both sides are turned simultaneously along screw hole A. During the screw turning process, the height adjustment of the top of the screw drives the height adjustment of the horizontal plate. The height of the horizontal plate is adjusted according to the length specifications of the punch and the capacitor shell, so that when the punch moves to the upper limit position, its bottom is exactly inside the horizontal plate. At this time, the capacitor shell is processed. After extrusion is completed... The punch moves the formed outer shell out, and the retaining ring fits perfectly against the punch surface. During the punch's upward movement, the retaining ring pushes the formed workpiece off the outer periphery of the punch, achieving automatic unloading, facilitating removal, and reducing manual operation. A screw hole B is provided inside the horizontal plate, and the retaining ring is connected to the screw hole B and a bolt. When adjusting the mold, the bolt can be turned along the screw hole B. Turning the bolt causes the connecting ring to rotate inside the retaining ring, which in turn causes the retaining ring to move horizontally. Adjusting the spacing and position of the retaining rings ensures they fit perfectly against the outer periphery of the punch, ensuring accurate unloading. This method is easy to adjust and suitable for unloading with punches of different specifications. Attached Figure Description

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1-3As shown, a capacitor casing forming mold includes a machine body 1 and a stripping mechanism 2. The stripping mechanism 2 is provided inside the machine body 1. The stripping mechanism 2 includes a lower mold base 201, a lower mold core 202, an upper mold base 203, a punch 204, a sleeve 205, a screw hole A206, a screw 207, a horizontal plate 208, and a retaining ring 210. The lower mold base 201 is installed at the bottom inside the machine body 1, and the lower mold core 202 is installed inside the lower mold base 201. The power output end is equipped with a punch 204 corresponding to the position of the lower die core 202 via the upper die base 203. Both sides of the top of the lower die base 201 are fixedly connected to a sleeve 205, and the sleeve 205 has a vertically opened screw hole A206 inside. The sleeve 205 is screwed to a screw rod 207 through the screw hole A206, and a horizontal plate 208 is installed between the top ends of the screw rod 207. The horizontal plate 208 is movably connected to a retaining ring 210 corresponding to the position of the punch 204 inside.

[0018] The system also includes an adjustment mechanism 3. An adjustment mechanism 3 is provided at the connection between the horizontal plate 208 and the retaining ring 210. The adjustment mechanism 3 includes a screw hole B301, a bolt 302, and a connecting ring 303. Horizontally, screw holes B301 are provided at both ends of the horizontal plate 208. The horizontal plate 208 is screwed to the bolt 302 through the screw holes B301. A connecting ring 303 is provided at the end of the bolt 302 near the retaining ring 210, located inside the retaining ring 210. The horizontal plate 208 has screw holes B301 inside, and the bolt 302 is screwed to the bolt 302 through the screw holes B301. Hole B301 and bolt 302 are connected to retaining ring 210. When adjusting the mold, bolt 302 can be turned along bolt hole B301. When bolt 302 is turned, it drives connecting ring 303 to rotate inside retaining ring 210. This allows bolt 302 to be turned so that retaining ring 210 can move horizontally. Adjusting the spacing and position of retaining rings 210 ensures that retaining ring 210 fits perfectly against the outer circumference of punch 204, ensuring accurate stripping. It is easy to adjust and suitable for stripping punches 204 of different specifications.

[0019] The screw 207 has its end penetrating the interior of the horizontal plate 208. An end ring 209 is fixedly connected to the top of the screw 207 and is attached to the upper and lower sides of the surface of the horizontal plate 208. A rubber pad 211 is adhered to the opposite side of the surface of the retaining ring 210 and is attached to the surface of the punch 204. The end ring 209 connects the end of the screw 207 and the horizontal plate 208, connecting the horizontal plate 208 and the screw 207 together without affecting the screw 207's turning. The rubber pad 211 attached to the surface of the retaining ring 210 is attached to the surface of the punch 204, which can prevent the retaining ring 210 from causing wear to the punch 204.

[0020] In this design, the horizontal plate 208 has horizontally spaced limiting holes 304 on both sides of the screw hole B301. The retaining ring 210 has a limiting rod 305 welded to its surface and inserted into the limiting hole 304. The limiting rod 305 is inserted into the limiting hole 304 inside the horizontal plate 208 and limits the retaining ring 210, so that it can only move horizontally and will not rotate.

A sleeve 205 and a screw 207 structure are provided on both sides of the lower mold base 201. When adjusting the mold, the screws 207 on both sides are turned simultaneously along the screw hole A206. During the turning of the screws 207, the height of its top is adjusted, which drives the height adjustment of the horizontal plate 208. The height of the horizontal plate 208 is adjusted according to the length specifications of the punch 204 and the length specifications of the capacitor shell, so that when the punch 204 moves out to the upper limit position, its bottom is exactly placed inside the horizontal plate 208. At this time, the capacitor shell is processed. After the extrusion is completed, the punch 204... The formed outer shell is moved out, and the retaining ring 210 fits perfectly against the surface of the punch 204. During the upward movement of the punch 204, the retaining ring 210 can push the formed workpiece off the outer periphery of the punch 204, realizing automatic unloading, convenient removal, and reducing manual operation. The horizontal plate 208 has a screw hole B301 inside, which is connected to the retaining ring 210 through the screw hole B301 and the bolt 302. When adjusting the mold, the bolt 302 can be turned along the screw hole B301. When the bolt 302 is turned, it drives the connecting ring 303 to rotate inside the retaining ring 210, so that the turning of the bolt 302 can drive the horizontal movement of the retaining ring 210.
