Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an anti-adhesion injection mold. Background Art

[0002] Injection molds are molds used for plastic injection molding. They can form plastic products with complex shapes, high dimensional precision or with inserts in one go. Injection molds play an important role in the injection molding process. They not only control the shape and size of the product, but are also responsible for the filling and compacting process of the plastic material to ensure the integrity and consistency of the product.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN219583425U discloses an injection mold that is easy to demold. The device drives the gear to rotate through a motor, thereby rotating the drum through a gear ring. During the rotation of the drum, the threaded block is limited by the push rod, the mounting plate and the movable rod, so that the threaded block moves upward, so that the push plate slowly ejects the finished product in the lower mold. However, after the finished product is ejected, there is a probability that the finished product will adhere to the outer wall of the push plate, and the finished product is easily torn when taking out the product. In view of this, we propose an anti-adhesion injection mold. Utility Model Content

[0015] The utility model provides an anti-adhesion injection mold, which has the following beneficial effects:

[0016] (1) In the anti-adhesion injection mold, when the upper mold moves upward under the drive of the large hydraulic cylinder, the fixed rod fixedly connected to the upper mold will slide in the through groove. When the fixed rod slides a certain distance, the fixed rod will exert a force on the moving rod, causing the moving rod to move upward.

[0029] In the embodiment of the utility model, in order to prevent the shell from sticking to the top plate 431, specifically, the lower mold 43 is provided with a slide groove 434, the slide groove 434 is slidably connected to a slider 435, the outer wall of the slider 435 is fixedly connected to a scraper 436 and a cross bar 4351, the cross bar 4351 passes through the fixed plate 51 and is slidably connected to the fixed plate 51, the outer wall of the cross bar 4351 is fixedly connected to one end of a spring 4352, and the other end of the spring 4352 is fixedly connected to the outer wall of the fixed plate 51. Then, the slider 435 is hinged with a hinge rod 437, and the end of the hinge rod 437 away from the slider 435 is hinged with a moving rod 438, and the moving rod 438 is provided with a through slot 439.

[0030] When the upper mold 42 moves upward under the drive of the large hydraulic cylinder 41, the fixed rod 422 fixedly connected to the upper mold 42 will slide in the through groove 439. When the fixed rod 422 slides a certain distance, the fixed rod 422 will apply a force to the moving rod 438, causing the moving rod 438 to move upward. During this process, the hinged rod 437 will apply a force to the slider 435, causing the slider 435 to move toward the moving rod 438.

After a while, the small hydraulic cylinder 433 is started to make the top plate 431 push the shell out. When the top plate 431 is flush with the lower mold 43, the fixed rod 422 will exert a force on the moving rod 438. During this process, the hinged rod 437 will exert a force on the slider 435, so that the slider 435 drives the scraper 436 to slide along the outer wall of the top plate 431, so that the top plate 431 can be separated from the bottom of the shell. When the upper mold 42 moves downward under the drive of the large hydraulic cylinder 41, the slider 435 will drive the scraper 436 back to its original position under the elastic force of the spring 4352.
