Replacing non-standard components with standard ones can significantly simplify the production process of hot box parts, shorten the manufacturing cycle, and reduce costs. For instance, in a horizontal split box, the upper top core rod typically has a conventional structure (as shown in a), which is complex to manufacture, time-consuming, and expensive. By modifying it using two standard parts (as shown in b), the design becomes more efficient and cost-effective. The traditional structure (irrational) is replaced by a new, rational design that improves functionality and usability.
Applying more factory-standard parts to the hot box—excluding non-standard elements outside the core box—can be developed as a series of standardized components, which can be easily sourced when needed. This approach is especially beneficial for specialized foundries that frequently use hot core box processes. It not only streamlines the design and manufacturing of hot core boxes but also enables faster development and production. This is a major step toward improving efficiency and reducing overall costs.
Parts of the hot box that can be converted into "factory standard parts" fall into several categories: (1) Box pins, box pin sleeves, pressure plates, and extended box pins; (2) Upper and lower top core plates, base frames for core drop methods, and moving frames for core shooting machines; (3) Open boxes and brackets used in multi-opening hot boxes; (4) T-shaped grooves and guide rods for top cores in certain core shooting machines like GSR2; (5) Left and right top core plates in vertical boxes; (6) Lower top core rods, return guide rods, and open box rods for multi-opening core shooting machines such as GSRZ.
Parts from category (1) through (5) are ideal candidates for developing a range of factory-standard components. However, for category (6), the size and dimensions depend on the specific hot box design, making it challenging to apply standard parts universally. In such cases, samples of these parts—sometimes including those from earlier categories—are designed as standard components. A few dimensions are symbolized, and then filled based on the actual conditions of each hot box.
By implementing this method, once the factory standard parts for the hot box are established, the design and production speed can be greatly improved, leading to reduced wood mold costs and overall production expenses. Using universal parts effectively is another key strategy in hot box design. In addition to using standard parts and factory standards, efforts should be made to replace non-standard parts on similar core shooting machines with universal components. This allows for greater commonality among parts used across the same type of core or similar castings, reducing the need for custom parts.
For example, in our 6105 and 6108 six-cylinder crankcase sand core boxes, along with front and rear end face hot core boxes, each set produces two different sand cores. These eight sets of hot core boxes are operated on just two 2ZZ8640A core shooting machines. The upper core plate and water-cooled sandblasting plate are used universally. Achieving this level of versatility in design and manufacturing helps meet the core requirements for large batches of crankshaft cores from different cylinder blocks.
The versatility of the upper core plate and water-cooled sandblasting plate allows for quick replacement of hot core boxes. Additionally, our factory also uses a 4ZZ8640A core shooting machine for the front and rear end faces of four-cylinder engine blocks (4110). This machine shares the same upper core plate and water-cooled sandblasting plate with the 6105 and 6108 models, further enhancing efficiency and resource utilization.
This approach not only reduces the workload at the hot box production plant and lowers mold production costs, but also boosts the efficiency of the core shooter, achieving a multiplicative effect. To realize the "shared" use of upper core boards and water-cooled sandblasting plates for different cylinder core castings, one crucial technical factor is the smooth arrangement of the sand cores.
Another important aspect of the horizontal split box hot box is the production process and materials used for the water-cooled sandblasting board. Traditionally, this part was made from cast iron, which is costly, time-consuming, and lacks versatility. However, alternative materials and more efficient manufacturing techniques could offer better performance and broader applicability, making it a key area for improvement and innovation.
Eelectrician Tool Backpack is a type of backpack designed specifically for electricians to carry and organize their tools while on the job. These backpacks typically have a variety of compartments and pockets that are specifically designed to hold different types of tools, such as pliers, wire cutters, screwdrivers, and more. They may also have features such as padded straps and back panels for comfort during extended periods of wear, durable materials to withstand wear and tear, and waterproofing to protect the tools from moisture.
Some key features to look for in an electrician tool backpack include:
-
Organization: Look for a backpack with multiple compartments and pockets, and consider whether the layout will work well for the specific tools you need to carry.
-
Durability: The backpack should be made from sturdy materials that can withstand the weight of your tools and resist wear and tear.
-
Comfort: Look for a backpack with padded straps and a padded back panel for comfort during extended wear.
-
Weather resistance: If you work outdoors or in wet environments, consider a backpack that is waterproof or at least water-resistant to protect your tools from moisture.
-
Capacity: Consider the size of the backpack and whether it will comfortably hold all the tools you need to carry.
The best electrician tool backpack for you will depend on your specific needs and preferences, so be sure to do your research and read reviews from other electricians before making a purchase. Please contact us if you have any preference to tool backpack.
