Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically, to an injection mold which is convenient for discharging finished products. Background Art

[0002] In the production process of plastic products, injection mold is a commonly used tool, which injects molten plastic material into the mold cavity, cools and solidifies to form the required plastic product. Finished product discharge is a key step in the injection mold, which involves taking the molded product out of the mold. In the use of existing injection molds, after the product is formed, most of the molded products are taken out of the mold cavity by technicians or by robotic arms. After the plastic product is solidified in the mold, it may have a close adhesion to the mold cavity, making it difficult to take the product out smoothly, which may cause deformation, damage or incomplete demolding of the product, and is inconvenient to discharge the molded product, greatly reducing the working efficiency of the device, thereby reducing the practicality of the injection mold and the production quality of the product. In order to address the deficiencies of the prior art, we propose an injection mold that is convenient for finished product discharge. Utility Model Content

[0023] Among them, the first sliding block 23 is slidably connected to the outer surface of the support rod 1, the push rod 25 is also connected to the inner wall of the movable mold 21, the push plate 26 slides on the inner wall of the movable mold 21, and the second sliding block 29 is slidably connected to the outer surface of the support rod 1;

[0024] When the movable mold 21 is sliding, the two No. 2 sliding blocks 29 are blocked, so that the connecting rod 28 is fixed, and then the movable mold 21 slides on the outer surface of the push rod 25, squeezing the No. 1 buffer spring 27, reducing the pressure of the movable mold 21, so that the push plate 26 pushes the product formed in the inner cavity of the movable mold 21, causing the product to fall automatically.

[0025] Among them, the fixed mold assembly 3 includes a fixed mold 31, a buffer rod 32 is fixedly installed on the inner wall of one side of the fixed mold 31, and a No. 2 buffer spring 33 is sleeved on the outer surface of the buffer rod 32. Fixed blocks 34 are welded on the outer surfaces of both sides of the fixed mold 31. A baffle plate 35 is arranged on one side of the fixed mold 31, and a sliding kit 36 ​​is symmetrically welded on the outer surface of one side of the baffle plate 35, and a plug 37 is slidably connected to the inner wall of the sliding kit 36.

[0027] By inserting the buffer rod 32 into the buffer groove 201, the No. 2 buffer spring 33 is squeezed to reduce the collision force between the movable mold 21 and the fixed mold 31, and the plug 37 is removed to allow the sliding kit 36 ​​and the baffle 35 to slide on the outer surface of the support rod 1. After selecting the position of the baffle 35, the plug 37 is inserted into the inside of the hole 4 through the sliding kit 36.

First, according to actual requirements, the plug 37 is taken out to push the sliding kit 36 ​​and the baffle 35 to slide on the outer surface of the support rod 1. After selecting the position of the baffle 35, the plug 37 is inserted into the inside of the socket 4 through the sliding kit 36. After completion, the driving mechanism is started to drive the movable mold 21 close to the fixed mold 31, so that the buffer rod 32 is inserted into the inner wall of the buffer groove 201. At this time, the No. 2 buffer spring 33 is compressed to reduce the distance between the movable mold 21 and the fixed mold 31. The collision force between them, when the movable mold 21 and the fixed mold 31 are closed, the inside of the device is injection molded. After the injection molding is completed, the driving mechanism is started to drive the movable mold 21 to move between the support rods 1 through the No. 1 sliding block 23 and the No. 2 sliding block 29. When the two No. 2 sliding blocks 29 contact the outer surface of one side of the baffle 35, the connecting rod 28 and the push rod 25 do not move, and the movable mold 21 continues to move to compress the No. 1 buffer spring 27, driving the push plate 26 to slide on the inner wall of the movable mold 21, thereby pushing out the molded product and making it slide, which greatly facilitates the discharge of the finished product, thereby improving the working efficiency of the device.
