Description

Technical Field

[0001] The invention relates to the field of stamping technology, in particular to a stamping injection mold. Background Art

[0002] At present, stamping dies are a processing method in which a mold installed on a press is used to apply pressure to the material during cold stamping processing, causing it to separate or plastically deform, thereby obtaining the required parts. In the stamping die, the stamped parts will stay in the lower die core and need to be picked up manually, so there is a risk of accidents. Therefore, we propose a stamping injection mold.

[0003] Announcement No. CN212070159U discloses a stamping injection mold, in which a fixed plate is fixedly installed on the left side of the lower mold core through a second spring. When the upper mold core and the lower mold core are in the stamping process, the fixed plate sinks under the pressure. When the stamping is completed, the fixed plate rebounds under the elastic force to pop the stamped part out of the lower mold core. Through such a structure, the stamped part can be automatically popped out, reducing the risk of accidents caused by manual handling of the stamped part. The running tracks of the upper mounting seat and the lower mounting seat are limited by setting a limit column and a limit hole. At the same time, a rubber pad can be detachably installed on the limit column to reduce the stress of the collision between the upper mounting seat and the lower mounting seat, which can effectively extend the service life of the mold. However, the patent still has the following problems in actual use:

[0004] The stamping injection mold is fixed with a fixed plate on the left side of the lower mold core through a second spring. When the upper mold core and the lower mold core are undergoing a stamping process, the fixed plate sinks under pressure. When the stamping is completed, the fixed plate rebounds under elastic force to eject the stamped part out of the lower mold core. However, when stamping and injection molding of hot materials is performed, the injection molded part is taken out of the mold by ejection. Due to the elastic force of the spring, the fixed plate will squeeze and deform the injection molded part, thereby affecting the molding quality of the injection molded part.

[0005] Therefore a stamping injection mold is proposed to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a stamping injection mold to solve the problem raised in the above background technology that when stamping and injection molding of hot materials is performed, the injection molded part is taken out from the inside of the mold by ejection.

[0022] 1. By setting up the discharging mechanism, not only can the inspection window on the front of the bottom mold fixing box be used to inspect and repair the injection mold, but also the ejection motor can be started to drive the first sprocket transmission assembly and the ejection threaded rod to rotate, so that the ejection threaded sleeve drives the clamping plate to move up and down.

When the injection molded part needs to be removed from When taking out the bottom mold body, the clamping plate can be lowered to make the limit plate and the second clamping sliding rod contact with the bottom of the bottom mold fixing box, and the limit plate on the top of the second clamping sliding rod will eject the injection molded part from the inside of the bottom mold body. This method is suitable for sheet materials and materials with higher hardness.

When the second lifting plate rises, under the action of the roller bracket and the fixed pulley, the connecting wire pulls the clamping block, thereby realizing the separation of the bottom mold body, and thus taking the injection molded part out of the inside of the bottom mold body;

[0023] 2. By setting the stamping mechanism, not only can the lifting motor be used to drive the second sprocket transmission assembly and the lifting threaded rod to rotate, so that the lifting threaded sleeve drives the second lifting plate to lift and move, and the stamping of the injection mold is realized by the press, but also the adjusting two-way threaded rod is driven to rotate by rotating the adjusting knob, so that the two adjusting threaded sleeves slide relative to each other and drive the adjusting rotating rod to rotate, thereby realizing the lifting and lowering movement of the adjusting support plate, and the distance between the pressure plate and the mounting bracket can be adjusted while the adjusting support plate supports the pressure plate.

The adjusting two-way threaded rod 219 is driven to rotate by rotating the adjusting knob 218, so that the two adjusting threaded sleeves 220 slide relative to each other and drive the adjusting rotating rod 221 to rotate, thereby realizing the lifting and lowering movement of the adjusting support plate 222.

[0040] The top of the two adjusting rotating rods 221 is rotatably connected with an adjusting support plate 222, the bottom of the mounting sliding sleeve 213 is fixedly installed with a mounting support 223, the bottom of the mounting support 223 is rotatably connected with a mounting rotating frame 224, the inside of the mounting rotating frame 224 is fixedly installed with a clamping sliding rod 225, the outer side of the clamping sliding rod 225 is slidably connected with a clamping sliding sleeve 226, one side of the clamping sliding sleeve 226 is fixedly installed with a clamping spring 227, the top of the clamping sliding sleeve 226 is rotatably connected with a clamping rotating rod 228, the end of the clamping rotating rod 228 is rotatably connected with a mounting rotating plate 229, and connecting rings 230 are symmetrically installed on both sides of the second lifting plate 207.

[0041] Working principle: Before using this stamping injection mold, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11 As shown, first, start the ejection motor 106 to drive the first sprocket transmission assembly 107 and the ejection threaded rod 108 to rotate, so that the ejection threaded sleeve 109 drives the clamping plate 110 to move up and down. When the clamping plate 110 descends and the limit plate 120 and the second clamping sliding rod 119 contact the bottom of the bottom mold fixing box 101, under the action of the clamping rotating rod 117, the clamping sliding sleeve 116 can drive the clamping arm 124 to unfold, and the bottom mold body 113 is placed on the top of the clamping plate 110.

[0042] Secondly, the engaging block 129 is engaged with the mounting slot 114 to connect the engaging block 129 with the bottom mold body 113. When the molded part needs to be taken out from the bottom mold body 113, the clamping plate 110 can be lowered to make the limit plate 120 and the second clamping sliding rod 119 contact the bottom of the bottom mold fixing box 101. The limit plate 120 on the top of the second clamping sliding rod 119 ejects the molded part from the inside of the bottom mold body 113. This method is suitable for sheet materials and materials with higher hardness. When the material is ejected, since the material has not cooled completely and is relatively soft, the shape of the injection molded part will be damaged by ejection, thereby affecting the molding quality of the injection molded part. The connecting hook 131 at the end of the connecting steel wire 130 can be engaged with the connecting ring 230. When the second lifting plate 207 rises, under the action of the roller bracket 126 and the fixed pulley 127, the connecting steel wire 130 pulls the engaging block 129, thereby realizing the separation of the bottom mold body 113, thereby taking the injection molded part out from the inside of the bottom mold body 113.

[0043] Finally, the lifting motor 203 is used to drive the second sprocket transmission assembly 204 and the lifting threaded rod 205 to rotate, so that the lifting threaded sleeve 206 drives the second lifting plate 207 to move up and down, and the injection mold is punched by the press machine 210. The adjusting knob 218 is turned to drive the adjusting bidirectional threaded rod 219 to rotate, so that the two adjusting threaded sleeves 220 slide relative to each other and drive the adjusting rotating rod 221 to rotate, so that the lifting and lowering movement of the adjusting support plate 222 can be achieved. By adjusting the supporting plate 222 to support the pressure plate 211, the distance between the pressure plate 211 and the mounting bracket 215 can be adjusted. Under the action of the pressure rotating rod 212, the mounting sliding sleeve 213 can be installed. The mounting support 223 and the mounting rotating frame 224 are driven to move relative to each other, and the top mold is placed at the bottom of the mounting bracket 215. The installation sliding sleeve 213 is closed by the installation spring 216. The clamping sliding sleeve 226 and the clamping rotating rod 228 are driven to rotate by the clamping spring 227, so that the mounting rotating plate 229 can rotate and clamp the top mold at the same time, so as to install the top mold. When stamping, in order to improve the stamping stability of the entire device, the support plate 222 can be adjusted to fix the distance between the pressure plate 211 and the mounting bracket 215, so as to improve the stability of the stamping, and the inspection window 104 on the front of the bottom mold fixing box 101 can be used to inspect and repair the injection mold.
