Injection molding machine template casting, which is an important part in the injection molding machine, so when you understand the injection molding machine, you need to familiarize and understand the important part of the template, so that it has a correct understanding and is well used in the injection molding machine. Therefore, based on this requirement, the following will explain the knowledge of the injection molding machine template casting to achieve the above objectives.
1. Does the form work structure, strength and rigidity have a great influence on the injection molding machine template casting?
From a professional point of view, the main function of the injection molding machine template is to carry the mold, as well as complete a series of actions such as clamping, injection molding, mold opening and demoulding. Moreover, when the injection molding machine performs the clamping, the entire clamping mechanism will be elastically deformed, and the template will be greatly impacted, and the bending and the like will easily occur after being pressed, and the bending deformation of the template will affect the injection molding machine. The service life and the quality of the molded product, therefore, based on this, the structure, strength and rigidity of the injection molding machine template have a great influence on the injection molding machine.
2. Structural features of the injection molding machine template casting
In the injection molding machine template casting, there is a specific type of injection molding chassis template, and its structural characteristics are:
The four corners of the template are provided with four pull rod guiding holes and a template body with a main ejection hole in the middle, and a connecting rod bracket seat connected to the four corners of the template body and located inside the pulling rod guiding hole. At the top of the link bracket seat is a link lock shaft hole and a sub-plate fixed to the link lock shaft hole. In addition, the template body forms a cavity avoidance through the link bracket seat and the sub-plate. The center of the sub-plate is provided with an ejector cylinder positioning space, and an ejector cylinder mounting seat is symmetrically arranged on both sides of the ejector cylinder positioning hole.
3. Guide sleeve of injection molding machine template casting
The guide sleeve of the injection molding machine is designed for the purpose of good lubrication between the guide sleeve and the tie rod, and the loss of lubricating oil is small to ensure good performance and use effect of the injection molding machine template. The structure comprises a part of the guide sleeve body. The guide sleeve body is mounted on the movable template and is fixedly sleeved on the pull rod. The guide sleeve body axially opens the inner oil guiding groove around the inner side wall thereof, and is on the guide sleeve body. A plurality of oil guiding holes are formed, and the oil guiding grooves are respectively communicated with each oil guiding hole. In addition, a plurality of diverting grooves are formed on the inner side of the guide sleeve body in the lateral direction, and the diverting grooves are corresponding to the oil guiding holes, and the diverting grooves are in communication with the inner oil guiding grooves.www.xihuafoundry.com
