SMC Civil Air Defense Door Mould

• Multi-insert splicing structure: It is composed of an upper template and a lower template, and the upper and lower templates are respectively provided with splicing upper and splicing lower insert structures. These inserts are usually rectangular in design and are removable to the formwork by means of a limit connection structure, such as a number of No. 1 connectors for connecting the lower formwork and the rectangular lower insert, and No. 2 connectors for connecting the upper formwork and the rectangular upper insert.

• Forming cavity: A forming cavity is arranged between the upper template and the lower template for forming air defense door products.

• Multi-rod ejector mechanism: located on the lower side of the lower template, including the top plate and a number of lifting drivers that can drive the top plate to lift up and down in the vertical direction, and a number of vertical vertical ejector rods are fixed on the top plate, which is easy to push out the air defense door products smoothly after forming.

• Reduce maintenance costs: With multi-insert splicing structure, when the mold is damaged during use, only the insert of the damaged part needs to be replaced, without the need to replace the upper template and the lower template as a whole, which can greatly reduce the later maintenance cost of the mold.

• Improve production efficiency: The multi-rod ejector mechanism can quickly and smoothly push the formed civil air defense door out of the mold, reducing the picking time and improving production efficiency. In addition, the design of the mold is also conducive to rapid mold loading, mold closing and mold release, shortening the time of each production cycle.

• Ensure product quality: The splicing insert structure can improve the manufacturing accuracy of the mold to a certain extent, because each insert can be machined and debugged separately, making it easier to ensure dimensional accuracy and surface quality. At the same time, the use of the mold temperature machine can accurately control the mold temperature to ensure that the temperature of the entire mold is stable and consistent, which helps to prevent local overheating or undercooling, avoid bubbles, warping or defects during the molding process, so as to improve the appearance and structural quality of the product.

• Die steel: such as P20 steel, etc., has good strength, toughness and machining performance, can meet the service life and accuracy requirements of the mold, but also easy to process and manufacture.

Insert material: Generally use good wear resistance, high hardness of steel, such as Cr12MoV, to ensure that the insert in the frequent molding process is not easy to wear, maintain the accuracy of the mold and product quality.

• Other auxiliary materials: including connectors such as bolts and nuts for connecting inserts and templates, as well as standard parts such as ejector rods, guide posts and guide bushings, the quality of these materials will also affect the overall performance and service life of the mould.
