Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold slider structure. Background Technology

[0002] Injection molds are core tools used to produce plastic products. They are widely used in the automotive, electronics, medical, and consumer goods industries by injecting molten plastic into a mold cavity and allowing it to cool and solidify. Their structure typically consists of a moving mold, a fixed mold, and systems for molding, gating, demolding, side core pulling, temperature control, and venting. They are classified into thermosetting / thermoplastic molds, single / multi-cavity molds, etc. With technological advancements, injection molds are evolving towards digitalization, intelligence, and green manufacturing to improve efficiency, precision, and sustainability.

[0003] According to a sliding block injection mold published on the China Patent Network with publication number CN211074509U, which relates to the field of auxiliary devices for molds, this invention addresses the problem that existing sliding block injection molds often require manual operation when pushing the sliding rod, resulting in high labor costs. A stationary injection mold block is located at the middle of the upper end of the injection base plate, and a moving injection mold block is located above the stationary block. The stationary and moving injection mold blocks are connected by a slot. The four corners inside the stationary and moving injection mold blocks are also addressed. Each part is provided with a limit rod placement groove, and a limit rod is installed inside the limit rod placement groove. The limit rod is welded to the injection base plate. A sliding plate is provided below the injection mold moving block, and the sliding plate is connected to the injection mold moving block through a slot. A push bottom column is provided at the upper end of the sliding plate, and there are two push bottom columns. However, the replacement of the slider structure of this injection mold is relatively cumbersome, and it is difficult to easily disassemble and replace the slider core-pulling assembly. When the slider core-pulling assembly is damaged, the entire injection mold needs to be disassembled before it can be disassembled, which increases the workload of the user.

[0004] Therefore, it is necessary to redesign and modify the injection mold to effectively prevent the phenomenon of difficulty in disassembly and assembly. Utility Model Content

[0027] Replacement component 2 includes a hydraulic cylinder 201, which is located on the right side of the mold body 1. A slider assembly 202 is fixedly connected to the left side of the hydraulic cylinder 201. A forming block 203 is provided inside the slider assembly 202. The slider assembly 202 is located inside the mold body 1. A support plate 204 is fixedly connected to the right side of the mold body 1. A limit frame 205 is provided on the top of the support plate 204. The limit frame 205 is located on the surface of the hydraulic cylinder 201. A moving block 206 is fixedly connected to the left side of the limit frame 205. A rotating rod 207 is threadedly connected inside the moving block 206. The rotating rod 207 is located to the left of the limit frame 205.

[0028] refer to Figure 4 The assembly 3 includes a protrusion 301. The left side of the protrusion 301 is fixedly connected to the right side of the forming block 203. Both the protrusion 301 and the slider assembly 202 have trapezoidal blocks 302 inside. The top of the trapezoidal block 302 extends through to the top of the protrusion 301 and is fixedly connected to a spring plate 303. The top of the spring plate 303 is fixedly connected to a right-angle plate 304. The left side of the right-angle plate 304 is fixedly connected to the right side of the slider assembly 202.

[0029] As a technical optimization of this utility model, by setting the disassembly and assembly component 3, the molding block 203 can be easily disassembled and installed, thereby improving the ease of disassembly and assembly of the molding block 203.

[0030] refer to Figure 4 The right-angle plate 304 has an opening 4 on its right side, and the trapezoidal block 302 has a connecting plate 5 fixedly connected to its right side. The connecting plate 5 is slidably connected to the opening 4.

[0031] As a technical optimization of this utility model, by setting the opening 4 and the connecting plate 5, it is easier for the user to pull the trapezoidal block 302, thus improving the ease of pulling the trapezoidal block 302.

[0032] refer to Figure 3 The top of the support plate 204 is provided with a sliding opening 6, and the bottom of the limiting frame 205 is fixedly connected with a sliding block 7, which is slidably connected to the sliding opening 6.

[0033] As a technical optimization of this utility model, by setting the sliding port 6 and the sliding block 7, the limiting frame 205 can be limited, preventing the limiting frame 205 from shaking when moving, thus improving the moving stability of the limiting frame 205.

[0034] refer to Figure 4 The top of the trapezoidal block 302 is fixedly connected to the limiting plate 8, and the top of the limiting plate 8 extends through to the top of the right angle plate 304.

[0035] As a technical optimization of this utility model, by setting the limiting plate 8, the trapezoidal block 302 can be limited, thereby improving the movement stability of the trapezoidal block 302.

[0036] refer to Figure 3 A rotating handle 9 is fixedly connected to the front side of the rotating rod 207, and the surface of the rotating handle 9 is provided with anti-slip texture.

[0037] As a technical optimization of this utility model, by setting a rotating handle 9, the user can easily rotate the rotating rod 207, thus improving the ease of rotation of the rotating rod 207.

[0038] The working principle and usage process of this utility model are as follows: When it is necessary to disassemble or assemble the slider assembly 202, the operator only needs to rotate the handle 9. The handle 9 will drive the rotating rod 207 to rotate synchronously. The rotating rod 207, through the threaded transmission mechanism, drives the moving block 206 to move smoothly outward. The moving block 206 then pushes the limiting frame 205 outward. During this process, the sliding block 7 limits the limiting frame 205 through the sliding port 6, effectively preventing it from shaking during movement, significantly improving the movement stability of the limiting frame 205, and thus smoothly displacing the hydraulic fluid. The cylinder 201 and the slider assembly 202 can be separated and disassembled. If installation is required, the above steps can be reversed. When the molding block 203 needs to be disassembled, the operator pulls the connecting plate 5 upward. The connecting plate 5 drives the trapezoidal block 302 to move upward synchronously, so that the trapezoidal block 302 and the protrusion 301 are separated. At this time, the molding block 203 can be pulled to the left to easily remove it. If the molding block 203 needs to be reinstalled, the above steps can be reversed to achieve quick installation. Through this design, the slider assembly 202 and the molding block 203 can be conveniently disassembled and assembled.

[0039] In summary, this injection mold slider structure allows for easy disassembly and replacement of the slider core-pulling assembly by replacing components. When the slider core-pulling assembly is damaged, it can be disassembled without disassembling the entire injection mold, reducing the user's workload and solving the problem of difficult disassembly and assembly.
