Description

Technical Field

[0001] This utility model relates to the field of workpiece desprue, specifically to a high-efficiency demolding and desprue device with mold linkage. Background Technology

[0002] A sprue removal device is a key component in injection molding, primarily used to automatically remove excess sprue material (runner waste) remaining after casting. Its core function is to precisely cut or separate the sprue during mold opening, driven mechanically, hydraulically, or pneumatically, improving production efficiency, reducing manual trimming processes, and preventing product damage. Common types include mechanical pull-out, ejector pin ejection, and hot runner needle valve control, widely used in precision injection molding of plastics and rubber, significantly reducing scrap rates and enabling automated production.

[0003] Chinese patent CN115972517A discloses an automatic dewatering device, including a worktable, a positioning mechanism mounted on the worktable, a clamping device, and an ultrasonic device. The positioning mechanism is used to position the material, and the clamping device is used to clamp the material from the positioning mechanism onto the ultrasonic device for ultrasonic dewatering, and then clamp the dewatered material off the ultrasonic device. The positioning mechanism includes a base, a support platform mounted on the base, and a rotary driver for driving the base to rotate. The support platform supports the material. This automatic dewatering device first adjusts the material position through the positioning mechanism, then uses the clamping device to clamp the material onto the ultrasonic device for dewatering, and then clamps and unloads the material, achieving automated dewatering.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] The base plate 1 is equipped with a workpiece self-removal mechanism 2 for automatically removing the molded workpiece in conjunction with the moving mold 4;

[0034] A cooling drain mechanism 3 is installed on the substrate 1 to accelerate workpiece cooling and automatically drain the water.

[0035] The workpiece self-removal mechanism 2 includes a linkage component 21, a workpiece clamping drive component 22, and a workpiece clamping component 23; the base plate 1, the cooling outlet mechanism 3, the moving mold 4, and the workpiece clamping drive component 22 are all connected to the linkage component 21; the workpiece clamping component 23 is connected to the workpiece clamping drive component 22; the linkage component 21 is used to drive the workpiece clamping drive component 22 in conjunction with the moving mold 4; the workpiece clamping drive component 22 is used to drive the workpiece clamping component 23 and limit the workpiece clamping component 23; the workpiece clamping component 23 is used to clamp the formed workpiece.

[0036] In this invention, after the moving mold 4 and the fixed mold 5 cooperate to form the workpiece, the moving mold 4 moves to the left to open and expose the workpiece. At the same time as the moving mold 4 moves to the left, the linkage component 21 drives the workpiece clamping component 23 to penetrate between the moving mold 4 and the fixed mold 5. Then, the workpiece clamping component 23 clamps the sprue of the formed workpiece, and under the drive and limit of the workpiece clamping drive component 22, the formed workpiece is taken out from the moving mold 4. Then, the moving mold 4 moves to the right and closes with the fixed mold 5 again to form the next workpiece. At the same time as the moving mold 4 moves to the right, the linkage component 21 drives the workpiece clamping component 23 to move out from between the moving mold 4 and the fixed mold 5, realizing the automatic removal of the formed workpiece from the moving mold 4 and the fixed mold 5 in linkage with the moving mold 4. The removed workpiece is quickly cooled by the cooling sprue removal mechanism 3 and automatically de-sprues.

[0037] The linkage component 21 includes a connecting rod 211, a slider 212, and a slide rail 213; one end of the connecting rod 211 is hinged to the front end of the moving mold 4, and the other end of the connecting rod 211 is hinged to the slider 212; the slider 212 is slidably connected to the slide rail 213; the lower end of the slide rail 213 is fixedly connected to the base plate 1 through a bracket; the slider 212 is connected to the workpiece clamping drive component 22; and the slide rail 213 is connected to the cooling drain mechanism 3.

[0040] In this invention, after the moving mold 4 and the fixed mold 5 cooperate to form the workpiece, the moving mold 4 moves to the left to open and expose the workpiece. Simultaneously, the moving mold 4 moves to the left, and the connecting rod 211 drives the slider 212 to slide backward along the slide rail 213. The slider 212, through the dual-axis cylinder 224, drives the fixing plate 221 to penetrate between the moving mold 4 and the fixed mold 5. Then, the cylinder 222 drives the transverse plate 231 to move the pneumatic gripper 232 to the left. After the pneumatic gripper 232 moves, it activates the sprue to clamp the formed workpiece. Then, the cylinder 222 drives the transverse plate 231 to reset and remove the workpiece from the moving mold 4. The moving mold 4 then moves to the right and closes with the fixed mold 5 again to form the next workpiece. Simultaneously, the moving mold 4 moves to the right, and the connecting rod 211 drives the slider 212 to slide forward along the slide rail 213. The slider 212 drives the fixing plate 221 to reset. This achieves automatic removal of the formed workpiece from the moving mold 4 and the fixed mold 5 in conjunction with the moving mold 4.

[0041] The cooling sprue removal mechanism 3 includes a sprue removal assembly 31, a workpiece sprue collection assembly 32, a linkage air-cooling assembly 33, and a push plate limiting support assembly 34; the base plate 1 and the dual-axis cylinder 224 are both connected to the sprue removal assembly 31; the workpiece sprue collection assembly 32 is connected to the base plate 1; the base plate 1, the slide rail 213, and the linkage air-cooling assembly 33 are all connected to the push plate limiting support assembly 34; the sprue removal assembly 31 is used to remove sprues from the formed workpiece; the workpiece sprue collection assembly 32 is used to collect the workpiece and sprues; the push plate 333 is used to rapidly cool the formed workpiece; the push plate limiting support assembly 34 is used to limit the linkage air-cooling assembly 33;

[0042] The drain assembly 31 includes a mounting plate 311 and an ultrasonic drain device 312; the lower end of the mounting plate 311 is fixedly connected to the base plate 1; the upper left side of the mounting plate 311 is fixedly connected to the ultrasonic drain device 312.

[0043] The ultrasonic dewatering device 312 adopts existing mature technologies in the field, such as the ultrasonic generator in an ultrasonic dewatering device disclosed in Chinese Patent CN221775159U, which will not be described in detail here.

[0044] The workpiece sprue collection assembly 32 includes a workpiece collection chamber 321 and a sprue collection chamber 322; both the workpiece collection chamber 321 and the sprue collection chamber 322 are fixedly connected to the base plate 1, and the sprue collection chamber 322 is located to the left of the workpiece collection chamber 321.

[0045] The linkage air-cooling component 33 includes a second fixed plate 331, a fan 332, and a push plate 333; the second fixed plate 331 is fixedly connected to the push plate 333; the fan 332 is rotatably connected to the lower rear end of the second fixed plate 331; and the push plate 333 is connected to the push plate limiting support component 34.

[0046] The push plate limiting support assembly 34 includes a fixed plate 341, a limiting rod 342, a return spring 343, and a slider 344; the rear end of the limiting rod 342 is fixedly connected to the push plate 333; the lower end of the push plate 333 is fixedly connected to the slider 344; the slider 344 is slidably connected to the slide rail 213; the front end of the limiting rod 342 is slidably connected to the fixed plate 341; the lower end of the fixed plate 341 is fixedly connected to the base plate 1; a return spring 343 is sleeved on the outer side of the limiting rod 342; one end of the return spring 343 is fixedly connected to the push plate 333, and the other end of the return spring 343 is fixedly connected to the fixed plate 341.

[0047] In this invention, the moving mold 4 moves to the right and closes with the fixed mold 5 again to form the next workpiece. Simultaneously, the moving mold 4 moves to the right, and the connecting rod 211 drives the slider 212 to slide forward along the slide rail 213. The slider 212 slides forward and abuts against the rear end of the push plate 333. At this time, the workpiece is directly below the fan 332. An external motor drives the fan blades of the fan 332 to rotate and cool the workpiece. Then, the slider 212 continues to move forward, pushing the limit rod 342 and the fixed plate 341 to slide forward via the push plate 333. Simultaneously, the slider 344 slides forward along the slide rail 213. This continues until the moving mold 4 and the fixed mold 5 close. Then, the dual-axis cylinder 224 starts, pushing the cylinder 222 to move to the right. The cylinder 222 moves forward via the fixed plate 221. The transverse plate 231 and pneumatic gripper 232 move the molded workpiece to contact the ultrasonic sprue removal device 312. The ultrasonic sprue removal device 312 emits ultrasonic waves to cause the product stem to vibrate at high speed, thereby shaking off the sprue of the injection molded product. The shaken-off workpiece falls into the workpiece collection chamber 321. Then, the dual-axis cylinder 224 resets. After resetting, the pneumatic gripper 232 releases its grip on the sprue, and the sprue falls into the sprue collection chamber 322. Then, the moving mold 4 moves to the left to open and expose the workpiece. While the moving mold 4 moves to the left, the connecting rod 211 drives the slider 212 to slide backward along the slide rail 213 to a limited position. At the same time, the reset spring 343 pushes the push plate 333 to reset. This accelerates the cooling of the workpiece taken out of the mold and automatically removes the sprue from the workpiece after cooling.
