Description

Technical Field

[0001] This utility model relates to the field of molds, and more specifically, to an ultra-long lifespan stacked mold. Background Technology

[0002] Molds are tools used to create molded products. Different shapes of molds can be used to create products of different shapes. Stacked injection molds are mostly used to mold large flat parts, shallow cavity shell parts, small multi-cavity thin-walled parts, and parts that need to be mass-produced. Existing stacked molds have the following problems: Existing stacked molds generally use racks or bolts to drive the mold opening and closing sequence to achieve synchronous part removal and injection. However, due to the large number of layers (usually 2-4 layers) and dense number of cavities, the overall weight of stacked molds can be 3-5 times that of traditional single-layer molds. During long-term use, the mold is prone to sagging due to its own weight, resulting in uneven stress on the drive components and a sharp shortening of its lifespan. If maintenance is required, the mold needs to be disassembled, and frequent disassembly and assembly aggravates the wear and tear of mold components, forming a vicious cycle of "wear-maintenance-re-wear", which leads to a decrease in the service life of the mold.

[0027] Example

[0028] Reference Figure 1-2 , Figure 5-6 As shown, this utility model discloses an ultra-long lifespan stacked mold, including a fixed mold plate, several runner plates, and a moving mold plate. Cavity plates are arranged between the fixed mold plate and the runner plates, and between the moving mold plate and the runner plates. The cavity plates include an upper cavity plate and a lower cavity plate. Specifically, the lower cavity plate is installed on both ends of the runner plates, and the upper cavity plate is installed on the bottom of the fixed mold plate and on the moving mold plate, respectively. The movement of the fixed mold plate and the moving mold plate drives the opening and closing of the upper and lower cavity plates. A mold core is set in the lower cavity plate, and an air ejector is installed in the mold core. After injection molding, the product is ejected from the lower mold core using gas through the air ejector, achieving ejector-free demolding. Compared with the traditional structure using an ejector plate for demolding, this utility model eliminates the need for an ejector plate, reducing mating parts by more than 30%, lowering the risk of wear, and increasing the mold's service life.

[0029] Furthermore, the cavity plates include four: two cavity plates are set between the fixed mold plate and the runner plate, and two cavity plates are set between the moving mold plate and the runner plate, allowing four products (flying discs) to be molded at one time, thus improving the efficiency of mold injection.

[0030] Reference Figure 3-4 As shown, a rifled rod drive mechanism is installed on both sides of the flow channel plate. The rifled rod drive mechanism includes a double-ended screw and copper sleeves. A fixing block is installed in the middle of the double-ended screw via a bearing. The fixing block is installed and fixed on both sides of the flow channel plate. A fixed module and a moving module are installed on the copper sleeves. The fixed module is connected to the fixed template, and the moving module is connected to the moving template. An oil nozzle is installed on the fixing block, which connects to the inside of the fixing block and the double-ended screw. Specifically, the rotation of the double-ended screw drives the copper sleeves on both sides to move back and forth linearly along the double-ended screw. The fixed module and the moving module are respectively installed on the two copper sleeves. The fixed module is connected to the fixed template, and the moving module is connected to the moving template, thereby realizing the movement of the fixed template and the moving template, realizing mold opening and closing. This utility model has an oil nozzle installed on the fixing block, which, together with an external intelligent automatic lubrication system, injects lubricating oil into the double-ended screw. It achieves full-cycle, dead-angle-free lubrication of the drive components without disassembly, solving the problems of untimely and insufficient lubrication in traditional methods, and improving the service life of the mold.

[0031] In addition, the upper and lower end faces of the runner plate are respectively provided with convex first positioning blocks, and the bottom edge of the fixed mold plate and the upper end face of the moving mold plate are respectively provided with concave second positioning blocks. When the mold is closed, the first positioning block is aligned with the second positioning block. The concave and convex fit realizes the precise fit of the moving mold plate, the fixed mold plate and the runner plate, avoids misalignment and improves the service life of the mold.

[0032] Reference Figure 2 As shown, a support base is further provided on the side of the flow channel plate. The support base extends to both ends to form an installation part, and the mold is fixedly installed through the installation equipment of the support base.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
