Description

Technical Field

[0001] This utility model relates to the field of hot runner technology, specifically to a rectangular hot nozzle and a structure with multiple nozzle tips arranged side by side or in a single row. Background Technology

[0002] Hot runner systems are heating components used in injection molds to inject molten plastic particles into the mold cavity. Hot runner molds are a novel structure that heats the runners and sprues of traditional or three-plate molds, eliminating the need to remove them during each molding process. Hot runners maintain the plastic in the runners and gates in a molten state through heating. A hot runner system generally consists of several parts, including hot nozzles, manifolds, a temperature control box, and accessories. Hot nozzles generally include two types: open hot nozzles and needle valve hot nozzles. Since the type of hot nozzle directly determines the selection of the hot runner system and the manufacturing of the mold, hot runner systems are often correspondingly divided into open hot runner systems and needle valve hot runner systems.

[0003] Existing hot runners have the following defects:

[0004] Existing hot nozzles are usually circular in design, with each nozzle corresponding to a single tip, resulting in low production efficiency. For applications that require the simultaneous production of multiple products, traditional designs necessitate multiple independent hot nozzles and flow channel systems, increasing equipment complexity and cost.

[0005] Therefore, a solution is needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] Example

[0024] Regarding the problem 1 that needs to be solved above: Existing hot nozzles are usually circular in design, with each hot nozzle corresponding to a tip, resulting in low production efficiency. For application scenarios that require the simultaneous production of multiple products, the traditional design requires multiple independent hot nozzles and flow channel systems, which increases the complexity and cost of the equipment.

[0025] The solution is as follows: a rectangular hot nozzle and a multi-tip parallel or single-row arrangement structure, including a device body 1. The device body 1 includes a mounting base 2, a conveying base 3, and nozzles 4. The mounting base 2 and the conveying base 3 are smoothly transitioned and integrally formed. The mounting base 2 is located on top of the conveying base 3, and both the mounting base 2 and the conveying base 3 are rectangular in shape. The bottom of the conveying base 3 is provided with a mounting head 5. There is a group of mounting heads 5, which are symmetrically distributed. Each group of mounting heads 5 has an embedded mounting groove 6 at its bottom. The nozzles 4 are installed in the embedded mounting grooves 6. The conveying base 3 has several sets of conveying channels 7 inside, which are connected to the embedded mounting grooves 6. The mounting head 5 has a main conveying groove 8 inside, which is semi-circular in shape. The main conveying groove 8 is connected to the several sets of conveying channels 7. The structure includes an outlet channel 13, a continuous channel 14, and a connecting threaded block 15. The outlet channel 13, the continuous channel 14, and the connecting threaded block 15 are smoothly transitioned and integrally formed. The outlet channel 13 is located at the top of the continuous channel 14 and is distributed in an inclined manner. The top of the outlet channel 13 has an arc-shaped structure. The connecting threaded block 15 is located at the bottom of the continuous channel 14 and has a hollow cylindrical structure. The outlet channel 13, the continuous channel 14, and the connecting threaded block 15 are a through structure. In use, the material first enters the main conveying trough 8 in the mounting base 2. The material in the main conveying trough 8 is then diverted into several sets of conveying channels 7. The material inside the several sets of conveying channels 7 can then be diverted into several sets of nozzle tips 4 for outflow, thereby realizing the function of producing multiple products simultaneously on one hot nozzle.

[0026] The tip 4 has a cylindrical structure and a conical structure at the bottom. The tip 4 has a threaded connection cover 9 at the top, which has a funnel-shaped structure. The tip 4 has a locking outer ring 10 on the outside. The threaded connection cover 9 on the tip 4 is for the purpose of connection. When connecting, the tip 4 is fixed in the embedded mounting groove 6 by rotation.

[0027] Heating tubes 11 are provided on both the left and right sides inside the conveying seat 3. The heating tubes 11 are located on the side of the conveying channel 7. The heating tubes 11 are used to heat the conveying seat 3, thereby heating the material in the conveying channel 7. By setting the heating tubes 11 in this way, the uniformity and comprehensiveness of heating the material can be improved.

[0028] The mounting base 2 and the conveying base 3 are provided with a heat insulation layer 12 on their outer sides. The heat insulation layer 12 is made of ceramic material. By setting the heat insulation layer 12 made of ceramic material, the purpose of heat preservation and heat insulation can be effectively achieved, and the rate at which heat is generated in the mounting base 2 and the conveying base 3 can be reduced.

[0029] Working principle: During operation, the material first enters the main conveying trough 8 in the mounting base 2. The material in the main conveying trough 8 is then diverted into several sets of conveying channels 7 (then the heating tube 11 is energized to heat the conveying base 3, thereby heating the material in the conveying channels 7. By setting the heating tube 11 in this way, the uniformity and comprehensiveness of heating the material can be improved). The material inside the several sets of conveying channels 7 can then be diverted into several sets of nozzles 4 for outflow, thus realizing the function of producing multiple products simultaneously on one hot nozzle.

[0030] The present invention comprises: 1. Device body; 2. Mounting base; 3. Conveying base; 4. Nozzle tip; 5. Mounting head; 6. Embedded mounting groove; 7. Conveying channel; 8. Main conveying groove; 9. Threaded connection cover; 10. Locking outer ring; 11. Heating tube; 12. Heat insulation layer; 13. Outlet channel; 14. Continuous channel; 15. Connecting threaded block. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that existing hot nozzles are usually circular in design, with each hot nozzle corresponding to a single nozzle tip, resulting in low production efficiency. For applications requiring the simultaneous production of multiple products, traditional designs require multiple independent hot nozzles and channel systems, increasing equipment complexity and cost. This invention, through the combination of the above components, enables the simultaneous production of multiple products on a single hot nozzle, effectively improving production efficiency and reducing costs.
