Stents are widely used in work and life, such as camera tripods and heart stents used in the medical field. However, an injection mold is used in the manufacturing process of the scaffold, and after injection molding, a demoulding mechanism is used to separate the material from the injection mold. However, the general demoulding mechanism has some disadvantages in use. The general demoulding mechanism is not convenient to eject the material in the injection mold of different brackets. Due to the different shapes of the materials in the injection molds of different scaffolds and the different sizes of the injection molds of scaffolds, it is not convenient to eject the materials in the injection molds of different scaffolds, thus affecting the use of the device.
 

The utility model aims to provide a demold mechanism of a stent injection mold to solve the problem of inconvenient topping in different stent injection molds mentioned in the background technology. In order to achieve the above, the utility model provides the following technical scheme: a bracket injection mold demoulding mechanism, including frame, a fixed spring and the second clamping bar, the top frame is equipped with air pump, air pump at one end connected to the frame center, fixed shelf rack, fixed channels with fixed, fixed channel for upper slope; One end of the connecting column is embedded in a fixed channel; The two sides of the frame are respectively provided with an electric push rod; One end of the electric push rod is connected with a clamping rod; The lower end of the connecting spring is provided with a connecting rod embedded in a limit slot, and the limit slot is located below a clip rod embedded in the injection mold body of the bracket. The longitudinal section of the frame is yamagata, and the sliding friction structure is formed between the frame and the fixed frame. The fixed column and the connecting column form a telescopic structure, and the connecting column is connected with the fixed channel buckle. A clamping rod is symmetrically arranged on both sides of the frame, and the first clamping rod is connected with the two clamping rods sliding. A clamping rod and the fixed rod form a rotating structure, the fixed rod and the two clamping rod thread connection, the two clamping rod for the "L" shape. The fixed rod and connecting rod form a telescopic structure, and the connecting rod and the limit slot are clamped.

Compared with the existing technology, the demoulding machine has the following beneficial effects:

1. When used, the stripper will push the material out from the inside of the scaffold injection mold by attaching the fixed frame to the bottom of the scaffold injection mold. Due to the large area of the fixed frame, different materials can be easily pushed out from the mold.

2. When used, the demoulder can adjust the height of the second clamping rod by rotating the rod connecting rod, which is convenient to clamp and limit different bracket injection mold body, and further facilitates the use of the device;

3. When used, the air pump is inflated into the frame, increasing the air pressure in the device, and moving upward to promote the fixed frame. When the fixator is in contact with the scaffold injection phantom, the air pressure in the device is further increased, and then air is ejected from the fixing channel, thereby ejecting the material from the scaffold injection phantom.
