Description

Technical Field

[0001] This utility model relates to the field of hot runner technology, and in particular to a hot runner system with one nozzle and eight nozzles. Background Technology

[0002] In conventional hot runner systems, the main nozzle typically corresponds to a single hot nozzle. The plastic material enters the single hot nozzle from the main nozzle and then flows into the mold cavity to form the product, which is very inefficient. Alternatively, the main nozzle corresponds to a single row of hot nozzles, with multiple hot nozzles arranged in a row. The plastic material enters the single row of multiple hot nozzles through the manifold from the main nozzle and then flows into the mold cavity to form the product. Although this method improves efficiency, the single-row arrangement of hot nozzles makes the entire hot runner system structure bulky and unsightly. Furthermore, this structure is not suitable for some specific product structures that require a denser arrangement of injection points.

[0003] Therefore, this paper aims to design a hot runner system with one nozzle and eight heads, which can improve production efficiency and make the structure more compact and aesthetically pleasing. Utility Model Content

[0004] In view of the above-mentioned shortcomings, this utility model provides a hot runner system with one nozzle and eight heads, which can improve production efficiency, make the structure more compact and beautiful, reduce volume and space occupation, and is suitable for products with dense glue inlet arrangement. It has strong applicability, ensures product qualification rate, and saves production costs.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] A hot runner system with one nozzle and eight heads includes an outer casing. Inside the outer casing are a manifold, a main nozzle, several hot nozzles, several telescopic cylinders, and a mold cavity. The manifold contains a main manifold. The main nozzle and hot nozzles are respectively installed at both ends of the manifold. The telescopic cylinders are connected one-to-one with each of the hot nozzles. Each hot nozzle contains eight secondary manifolds arranged in a circular array and eight nozzle cores. The main nozzle communicates with the eight secondary manifolds in each hot nozzle through the main manifold. Each telescopic cylinder is connected to the eight nozzle cores in each hot nozzle. When plastic material flows from the main nozzle through the main manifold into the eight secondary manifolds in each hot nozzle, the telescopic cylinders cause the eight nozzle cores in each hot nozzle to rise, connecting the eight secondary manifolds in each hot nozzle with the mold cavity, thereby allowing the plastic material to flow into the mold cavity and form a product.

[0007] According to one aspect of this utility model, after the center of the main diversion channel is connected to the main nozzle, several branches extend out from the periphery and are connected to several hot nozzles; the secondary diversion channel is inclined.

[0008] According to one aspect of this utility model, there are four hot nozzles, which are arranged in a rectangular array on the flow divider plate; the number and arrangement of the telescopic cylinders are consistent with the number and arrangement of the hot nozzles.

[0009] According to one aspect of the present invention, the main nozzle is connected to the center of the flow divider plate, the main nozzle is located at the center of the four telescopic cylinders, and the main nozzle is located at the center of the four hot nozzles.

[0010] According to one aspect of the present invention, the flow divider is embedded with heating discs, and the housing is also provided with heating wires, which are arranged in an alternating pattern around the main nozzle.

[0011] According to one aspect of this utility model, each telescopic cylinder is connected to eight nozzle cores in each hot nozzle via a connecting plate, wherein the telescopic cylinder is a pneumatic cylinder.

[0012] The advantages of this invention are as follows: When the plastic material flows from the main nozzle into the eight secondary channels of each hot nozzle through the main channel, the eight nozzle cores in each hot nozzle are raised by the telescopic cylinder, so that the eight secondary channels in each hot nozzle are connected to the mold cavity, thereby allowing the plastic material to flow into the mold cavity and form the product. By setting eight secondary channels and eight nozzle cores in a circumferential array, production efficiency can be improved, the structure can be made more compact and beautiful, the volume can be reduced, and the space occupied can be reduced. It is suitable for products with dense glue inlet points, has strong applicability, ensures product qualification rate, and saves production costs. Setting four hot nozzles in a rectangular array can also further improve production efficiency, make the structure more compact and beautiful, reduce the volume and space occupied, and is suitable for products with dense glue inlet points. It has strong applicability, ensures product qualification rate, and saves production costs. Attached Figure Description

[0020] like Figure 1 - Figure 3As shown, a hot runner system with one nozzle and eight nozzles includes an outer shell, a manifold, a main nozzle, several hot nozzles, several telescopic cylinders, a cavity, heating bars, and heating wires. The outer shell (not shown in the figure) can have any structure and is used to install the remaining components; the manifold, main nozzle, hot nozzles, telescopic cylinders, cavity (not shown in the figure), and heating wires are all located within the outer shell. The manifold is a plate-shaped structure, generally square, with a main flow channel inside for connecting the main nozzle and the hot nozzles. The main nozzle and hot nozzles are respectively installed at both ends of the manifold, with the main nozzle connected to the center of the manifold. There are four hot nozzles arranged in a rectangular array on the manifold; each hot nozzle contains eight secondary flow channels arranged in a circular array and eight nozzle cores. The main nozzle communicates with the eight secondary flow channels within each hot nozzle through the main flow channel. There are four telescopic cylinders arranged in a rectangular array on the manifold plate. Each telescopic cylinder is connected to a corresponding hot nozzle, and the number and arrangement of the telescopic cylinders are consistent with the number and arrangement of the hot nozzles. Each telescopic cylinder is connected to eight nozzle cores within each hot nozzle. The mold cavity (not shown in the figure) is used for product molding. The heating discs are embedded in the manifold plate to facilitate the smooth flow of plastic material within the manifold plate and the flow channels of the hot nozzles. The heating wires are arranged in a staggered pattern around the main nozzle to facilitate the smooth flow of plastic material within the main nozzle. When the plastic material flows from the main nozzle through the main flow channel into the eight secondary flow channels within each hot nozzle, the telescopic cylinders drive the eight nozzle cores within each hot nozzle to rise, connecting the eight secondary flow channels within each hot nozzle to the mold cavity, thereby allowing the plastic material to flow into the mold cavity and form the product. This system boasts high production efficiency, a simple, compact, and aesthetically pleasing structure, small size, minimal space occupation, and a wide range of applications. For specific structural products requiring denser and more compact glue inlet points, this structure ensures product qualification rates and saves production costs while meeting product requirements.

[0021] In practical applications, after the main flow channel is connected to the main nozzle, several branches extend outwards and connect to several hot nozzles. Specifically, four branches extend outwards from the center of the main flow channel and connect to four hot nozzles (which contain eight secondary flow channels). The secondary flow channels are inclined to facilitate the flow of plastic material directly from the main flow channel to the nozzle core inside the hot nozzle.

[0022] In practical applications, the main nozzle is located at the center of the four telescopic cylinders and the four hot nozzles. The four telescopic cylinders, or rather the four hot nozzles, are arranged around the main nozzle, making the structure more compact and aesthetically pleasing.

[0023] In practical applications, each telescopic cylinder is connected to eight nozzle cores within each hot nozzle via a connecting plate; the connecting plate can be any plate-shaped structure, such as a round plate or a square plate. The telescopic cylinder is a pneumatic cylinder.

[0024] The advantages of this invention are as follows: By setting eight sub-channels and eight nozzles in a circular array, production efficiency can be improved, the structure can be made more compact and aesthetically pleasing, the volume can be reduced, and the space occupied can be reduced. It is suitable for products with dense glue inlet arrangement, has strong applicability, ensures product qualification rate, and saves production costs. By setting four hot nozzles in a rectangular array, production efficiency can be further improved, the structure can be made more compact and aesthetically pleasing, the volume can be reduced, and the space occupied can be reduced. It is suitable for products with dense glue inlet arrangement, has strong applicability, ensures product qualification rate, and saves production costs.

[0025] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations, combinations, or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
