Description

Technical Field

[0001] This utility model belongs to the field of injection molding equipment technology, specifically relating to a novel hot runner temperature control system for blow-molded medicine bottle molds. Background Technology

[0002] When blow molding pharmaceutical bottles, the nozzle of the hot runner needs to be heated to keep the raw material in a molten state. As shown in the publication (announcement) number CN208841711U, the current method of heating the nozzle is to wrap a heating strip around the outer wall of the nozzle. In order to ensure heat transfer efficiency, the heating strip needs to be tightly wrapped around the nozzle.

[0003] Therefore, when heating the nozzle by wrapping the heating strip, the heating strip is not easy to move, and the heating position of the nozzle cannot be easily adjusted. This makes it inconvenient to adjust the heating position of the nozzle according to the type of raw material. When processing some raw materials, cold material at the nozzle and stringing may occur.

[0004] Therefore, this application proposes a novel hot runner temperature control system for blow-molded medicine bottle molds that allows for convenient adjustment of the heating position of the nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a novel hot runner temperature control system for blow-molded medicine bottle molds, in order to solve the current technical problem that it is inconvenient to adjust the heating position of the nozzle according to the type of raw material.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel hot runner temperature control system for blow-molded medicine bottle molds, including: a heating ring with an inner diameter larger than the outer diameter of the nozzle, which is fitted onto the horizontally arranged nozzle and then slides to any position of the nozzle and stops, and thermally engages with the expanded nozzle after heating the nozzle.

[0007] Furthermore, the inner diameter of the heating ring is 0.04 mm larger than the outer diameter of the nozzle.

[0008] Furthermore, the heating ring is provided with heating wires.

[0009] Furthermore, the heating wire extends from the wire seat on one side of the heating ring and is then mounted on the heating ring.

[0010] Furthermore, several nozzles are disposed on the flow divider plate, and each nozzle is fitted with at least one heating ring.

[0011] The beneficial effects of this utility model are that it aims to solve the technical problem of the inconvenience of adjusting the heating position of the nozzle according to the type of raw material. The inner diameter of the heating ring of this temperature regulation system is larger than the outer diameter of the nozzle, and the inner diameter of the heating ring is set to be only slightly larger than the outer diameter of the nozzle. In this way, the heating ring can slide smoothly on the nozzle before the nozzle is heated, which makes it very convenient to adjust the heating position of the nozzle according to the type of raw material to solve the problems of cold material and stringing at the injection gate. At the same time, after the injection molding machine starts, it heats the nozzle itself and thermally fits with the expanded nozzle to fix it to the nozzle, ensuring that the heating position of the nozzle remains stable during production. In addition, this temperature regulation system has a compact structure and can be used for short nozzles. Attached Figure Description

[0012] To more clearly illustrate the specific embodiments of this utility model or the technical solutions in the prior art, the drawings used in the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings in the following description are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0013] Figure 1 This is a top view of the novel hot runner temperature control system for blow-molded medicine bottle molds of this utility model. Figure 2 yes Figure 1 Enlarged view of point A in the middle; In the picture: Heating ring 100, nozzle 200, heating wire 300, wire base 400, flow divider 500. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments implemented by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example like Figure 1 As shown, this utility model provides a novel hot runner temperature control system for blow-molded medicine bottle molds, including: a heating ring 100, combined with... Figure 2 Its inner diameter is larger than the outer diameter of the nozzle 200, so that after being fitted onto the horizontally arranged nozzle 200, it can slide to any position of the nozzle 200 and stop, and after the nozzle 200 is heated, it can be thermally fitted with the expanded nozzle 200.

[0016] The inner diameter of the heating ring 100 in this temperature control system is larger than the outer diameter of the nozzle 200, and the inner diameter of the heating ring 100 is set to be only slightly larger than the outer diameter of the nozzle 200. In this way, the heating ring 100 can slide smoothly on the nozzle 200 before production when the nozzle 200 is not heated, making it very convenient to adjust the heating position of the nozzle 200 according to the type of raw material. When the injection molding machine starts, it heats the nozzle 200 itself and thermally fits with the expanded nozzle 200 to fix it to the nozzle 200, ensuring that the heating position of the nozzle 200 remains stable during production. In addition, this temperature control system has a compact structure and can be used for short nozzles 200.

[0017] In at least one embodiment, the inner diameter of the heating ring 100 is 0.04 mm larger than the outer diameter of the nozzle 200, so that when the heating ring 100 and the nozzle 200 are concentric, the gap between the heating ring 100 and the nozzle 200 is 0.02 mm. Before production, when the nozzle 200 is in a cooling state, the heating ring 100 can slide smoothly on the nozzle 200 and stop at any position, thereby adjusting the position of the heating ring 100 on the nozzle 200 according to the type of raw material. In this way, when the injection molding machine is started, the heating ring 100 heats up and heats the nozzle 200. The expanded nozzle 200 can thermally fit with the heating ring 100 to fix the heating ring 100 in place.

[0018] In at least one embodiment, the heating ring 100 is heated in the following manner: (e.g.) Figure 2 As shown, the heating ring 100 is provided with a heating wire 300. The heating wire 300 can be an electric heating wire, and the heating ring 100 can be a double-layer ring with an electric heating wire disposed between the rings.

[0019] like Figure 1 As shown, the heating wire 300 extends from the wire seat 400 on one side of the heating ring 100 and is then mounted on the heating ring 100. This arrangement of the heating wire 300 prevents the heating ring 100 from being pulled by the heating wire 300, ensuring that the heating ring 100 can be stably stopped at any position of the nozzle 200.

[0020] like Figure 1 As shown, when this temperature control system is actually used in injection molding production, it can be in the form of several nozzles 200 arranged on the manifold 500, and each nozzle 200 is fitted with at least one heating ring 100.

[0021] In summary, the inner diameter of the heating ring 100 in this temperature control system is larger than the outer diameter of the nozzle 200, and the inner diameter of the heating ring 100 is set to be only slightly larger than the outer diameter of the nozzle 200. This allows the heating ring 100 to slide smoothly on the nozzle 200 before production when the nozzle 200 is not heated, making it very convenient to adjust the heating position of the nozzle 200 according to the type of raw material to solve the problems of cold material at the injection gate and stringing. Furthermore, when the injection molding machine starts, the heating ring 100 heats the nozzle 200 itself and thermally fits with the expanded nozzle 200 to fix it in place, ensuring that the heating position of the nozzle 200 remains stable during production. In addition, this temperature control system has a compact structure and can be used with short nozzles 200.

The embodiments described above are merely illustrative. For example, the division of the mechanism is only a logical functional division, and there may be other division methods in actual implementation.
