Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a one-time molding mold. Background Technology

[0002] One-piece molding dies are a widely used tool in manufacturing. They can directly shape raw materials into the required shape and size in a single processing step. By using one-piece molding dies, manufacturers can significantly reduce the number of processes in the production process, thereby improving production efficiency and shortening product delivery cycles. Due to the reduction in the need for multiple processing and corrections, the scrap rate of products is also greatly reduced, thus saving costs.

[0003] Chinese patent discloses a one-time molding die (publication number: CN213728951U). This device uses a fixing box on the base, and the fixing box is equipped with four sets of adjustable clamping mechanisms to clamp and fix the die. The installation and disassembly of the die are very convenient, and it is easy to quickly change the die type according to different terminal models, which helps to improve work efficiency. However, the following problems still exist in this device:

[0004] The aforementioned device uses multiple cylinders to simultaneously move a push plate. The push plate can only clamp and fix molds of a single shape, and its clamping effect on irregularly shaped molds is poor. Therefore, a one-piece molding mold is proposed to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, a one-time forming mold includes a support mechanism 1, with a clamping mechanism 2 disposed in the middle of the support mechanism 1. The clamping mechanism 2 includes a support platform 201, with several limiting rails 202 fixedly connected to the outer wall of the support platform 201. Each limiting rail 202 has an upper moving plate 213 slidably connected to its inner wall, and the top of each upper moving plate 213 extends above the support platform 201. A connecting cylinder 214 is embedded and fixedly fixed to the top of the upper moving plate 213, and an insert rod 215 is penetratingly connected to the inner wall of the connecting cylinder 214. One end of the insert rod 215 extends to the outside of the connecting cylinder 214 and is fixedly connected to a clamping plate 217. Nuts 216 are threadedly fitted onto the outer wall of the insert rod 215 and on both sides of the connecting cylinder 214, with the sides of the nuts 216 abutting against the connecting cylinder 214. A lower forming mold 218 is placed in the middle of the top surface of the support platform 201, and the outer wall of the lower forming mold 218 abuts against the clamping plate 217. Figure 5 As shown, the outer surface of the insertion rod 215 is threaded, so that the nut 216 is connected by the thread;

[0029] A column 205 is rotatably connected to the center of the bottom surface of the support platform 201. A perforated ring 203 is fixedly connected to the bottom surface of the support platform 201 and to the outside of the column 205. A pin 204 is inserted through the inner wall of the perforated ring 203. A sleeve 206 is symmetrically fixedly connected to the upper end of the outer wall of the column 205. The inside of the sleeve 206 is inserted into the pin 204. Figures 3-4 As shown, several holes are formed on the surface of the hole ring 203, and the spacing between adjacent holes is consistent;

[0030] A lifting groove 207 is provided on the outer wall of the column 205. The lifting groove 207 is aligned with the column 205 in the length direction. An electric telescopic rod 208 is fixedly installed at the bottom of the column 205. A lifting block 209 is fixedly connected to the extended end of the electric telescopic rod 208. The side wall of the lifting block 209 extends out of the column 205 through the lifting groove 207. The side wall of the lifting block 209 is slidably connected along the inner side of the lifting groove 207. A ring rail 210 is fixedly connected to both the upper and lower ends of the side wall of the lifting block 209. Several lower moving plates 211 are slidably connected to the outer sides of the two ring rails 210. Each lower moving plate 211, located away from the ring rails 210, has a connecting rod 212 rotatably connected to its upper and lower ends at the side facing away from the ring rails 210. The end of the connecting rod 212, located away from the lower moving plate 211, is rotatably connected to the bottom of the upper moving plate 213. Figure 5 As shown, when the support platform 201 rotates relative to the column 205, each of the lower moving plates 211 rotates around the outer side of the annular track 210.

[0031] The support mechanism 1 includes an upper bracket 101. A hydraulic cylinder 102 is fixedly installed at the top center of the upper bracket 101. An upper forming mold 103 is fixedly installed at the bottom of the extended end of the hydraulic cylinder 102. Lower brackets 104 are symmetrically fixedly connected to the inner side of the upper bracket 101. The tops of the two lower brackets 104 are respectively fixedly installed on both sides of the outer wall of the limiting rail 202. The upper forming mold 103 is aligned with the lower forming mold 218 below it. Figure 1 As shown, the extension end of the hydraulic cylinder 102 drives the upper forming mold 103 to descend, thereby cooperating with the lower forming mold 218 to process the workpiece.

[0032] The working principle of this utility model:

[0033] Before clamping the lower forming mold 218, rotate the support platform 201 relative to the column 205. After each connecting cylinder 214 moves to a suitable angle, insert the pin 204 through the hole on the surface of the annular ring 203 and insert the end of the pin 204 into the sleeve 206, so that the column 205 and the support platform 201 remain relatively fixed. Then, insert the rods 215 one by one into the connecting cylinder 214. By adjusting the position of the rods 215 inside the connecting cylinder 214, the clamping position of each clamping plate 217 is adjusted. When fixing, tighten the nuts 216 on both sides of the connecting cylinder 214 where the rods 215 are located, until the nuts 216 abut against both sides of the connecting cylinder 214 respectively.

[0034] Secondly, the extension end of the electric telescopic rod 208 drives the lifting block 209 to rise, the lower moving plate 211 to rise, and the connecting rod 212 to move away from the column 205. The upper moving plate 213 drives the side clamping plate 217 away from the support platform 201. Then, the lower forming mold 218 is placed above the support platform 201. The extension end of the electric telescopic rod 208 drives the lifting block 209 to fall, and the connecting rod 212 moves towards the column 205. The upper moving plate 213 drives the side clamping plate 217 to approach and clamp the lower forming mold 218.
