Description

Technical Field

[0001] This utility model relates to the field of hot runner system technology, and in particular to a novel SR6 nozzle tip structure. Background Technology

[0002] (see Figures 1 to 5 The older SR3 nozzle structure includes a nozzle 1, a nozzle tip 2 that mates with the nozzle 1, and a nozzle cap 3 fitted onto the nozzle tip 2. During use, the plastic material enters from the main nozzle 4, is distributed to each nozzle 1 via a manifold 5, and then flows down through the nozzle tip 2 and through the gate into the mold cavity, completing the injection molding process. During product injection, the plastic material enters the cavity through the nozzle tip 2. If the gate temperature is too low, the plastic material will freeze and block the gate, causing no or unstable injection, thus affecting the product's balance. Furthermore, the older SR3 nozzle structure has the following drawbacks: A) The older SR3 nozzle tip and nozzle cap do not contact each other, leaving a 0.2mm gap; B) The gap between the older SR3 nozzle tip and nozzle cap is too small; C) The older SR3 nozzle tip is too short and does not extend into the gate.

[0003] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel SR6 nozzle tip structure to address the aforementioned shortcomings and defects of the existing technology.

[0005] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0006] A novel SR6 nozzle structure is characterized by comprising an SR6 nozzle structure disposed on a manifold plate. The SR6 nozzle structure includes a main nozzle disposed on the manifold plate, an SR6 nozzle disposed on the main nozzle and cooperating with the main nozzle, and a nozzle cap disposed on the main nozzle. The SR6 nozzle has a rhomboid structure. The rear end of the SR6 nozzle contacts the nozzle cap and is fitted with tolerances to ensure no gap between them. The gap between the front end of the SR6 nozzle and the nozzle cap forms a space for storing adhesive material. The front end of the SR6 nozzle extends into the gate.

[0007] In a preferred embodiment of this invention, the SR6 nozzle tip is made of an alloy material with increased wear resistance.

[0008] In a preferred embodiment of this invention, the nozzle cap is connected to the main nozzle by a thread.

[0009] Due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: Compared with the old SR3 nozzle structure, the SR6 nozzle tip structure of this utility model improves the gate temperature by optimizing the nozzle tip shape, reducing the nozzle tip size, increasing the gap between the nozzle tip and the nozzle cap to provide more space for storing the rubber material (this rubber material is constantly renewed during injection molding, and there will be no dead material). In addition, the nozzle tip is lengthened and extended to the gate to increase heat conduction. Furthermore, the contact between the nozzle tip and the nozzle cap is increased to increase heat conduction and improve the gate temperature. At the same time, the use of alloy material increases wear resistance. Combined with the above optimizations, the gate temperature is guaranteed, the discharge is stable, and the production efficiency is improved. The use of alloy material increases wear resistance.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] See Figure 6 The present invention discloses a novel SR6 nozzle tip structure, including an SR6 nozzle tip structure 10 disposed on a flow divider plate (not shown in the figure). In this embodiment, a main nozzle is disposed on the flow divider plate for inputting adhesive material.

[0019] The SR6 nozzle tip structure 10 includes a main nozzle 11 disposed on a flow divider plate, an SR6 nozzle tip 12 disposed on and cooperating with the main nozzle 11, and a nozzle cap 13 disposed on the main nozzle 11. In this embodiment, the nozzle cap 13 is threadedly connected to the main nozzle 11.

[0020] The SR6 nozzle tip 12 is designed with a diamond shape. The rear end 12a of the SR6 nozzle tip 12 is in contact with the nozzle cap 13 and the two are fitted with tolerances to ensure that there is no gap between them. The gap between the front end 12b of the SR6 nozzle tip 12 and the nozzle cap 13 forms a space a for storing the rubber material. The front end 12b of the SR6 nozzle tip 12 extends into the gate b.

[0021] To increase wear resistance, the SR6 nozzle tip 12 is made of an alloy material that enhances wear resistance.

[0022] Compared to the older nozzle design, the rear end 12a of the SR6 nozzle 12 in this invention contacts the nozzle cap 13, and the two are fitted together with tolerances to ensure no gap. This allows more heat from the nozzle cap 12 to be transferred to the SR6 nozzle 12, increasing the gate temperature. The gap between the front end 12b of the SR6 nozzle 12 and the nozzle cap 13 is also increased, providing more space at the gate (b) to store the resin. Since this resin is fluid and constantly replenished during product injection, the increased amount of resin between the nozzle cap 13 and the SR6 nozzle 12 generates more heat at the gate, thus improving the gate temperature. Temperature; The length of the SR6 nozzle tip 12 is extended into the gate b. Because the SR6 nozzle tip 12 has its own heat, it increases the temperature of the gate b. The SR6 nozzle tip 12 is made of alloy material, which increases wear resistance. Although the SR6 nozzle tip 12 can increase the gate temperature, it does not mean that the old nozzle tip SR3 has to be replaced. Relatively speaking, the gate temperature of the old nozzle tip SR3 is not as high as that of the new nozzle tip SR6. However, it can be used for plastic materials that do not have high requirements for gate temperature (such as PP, TPE, ABS, etc.). On the contrary, if these materials use the SR6 nozzle tip, the gate temperature will be too high, resulting in stringing and drooling problems.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
