Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically a hot runner structure for a suction head injection mold. Background Technology

[0002] Suction heads are widely used in medical, chemical and other fields. They are disposable consumables with large usage, so the production volume is also extremely large. For the injection molding process of suction heads, the traditional hot-to-cold runner structure or the fully hot structure is basically used.

[0003] During the heating process of injection molds, heating tubes are usually fixed inside the hot runner mounting plate by embedding. However, this method of installation makes disassembly troublesome when the heating tube is damaged, and it is not easy to replace the heating tube and the hot runner mounting plate. Moreover, the installation method of embedding the heating tube inside the hot runner mounting plate is also quite troublesome, making the assembly of the hot runner mounting plate more complicated. To address this, we propose a hot runner structure for suction head injection molds. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a hot runner structure for a suction head injection mold, which effectively solves the problems mentioned in the background art.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By providing a support groove, the contact area between the heating block and the hot runner assembly can be effectively increased, thereby improving the heating speed and uniformity of the hot runner assembly. By providing a feeding seat, which is engaged with the upper part of the hot runner assembly, the feeding seat can feed material into the interior of the hot runner assembly. The device heats the hot runner assembly through the heating block, which is detachable.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1-4 A hot runner structure for a suction head injection mold is provided, including a heating seat 10, a cover plate 20 and a hot runner assembly 30. The heating seat 10 is located on the upper part of the cover plate 20, and the hot runner assembly 30 is located on the opposite side of the heating seat 10 and the cover plate 20.

[0025] The heating base 10 includes a housing 11, with an installation cavity 12 inside the housing 11. A feeding seat 13 is located inside the installation cavity 12. Heating blocks 14 are installed inside the housing 11, and each heating block 14 has a support groove 15 inside its cavity. A hot runner assembly 30 is installed at the bottom of the heating blocks 14. During operation, the heating base 10 preheats the hot runner assembly 30, increasing its internal temperature and preheating and melting the injection molding material. A cover plate 20 secures the bottom of the hot runner assembly 30. The installation cavity 12 inside the housing 11 allows for the placement of the heating blocks 14, and the support grooves 15 effectively position the hot runner assembly 30. The device is designed to limit the placement of the hot runner assembly 30, allowing for better placement. The inclusion of a support groove 15 effectively increases the contact area between the heating block 14 and the hot runner assembly 30, thereby improving the heating speed and uniformity of the hot runner assembly 30. A feeding seat 13 engages with the upper part of the hot runner assembly 30, allowing for material feeding into the assembly. The device heats the hot runner assembly 30 via the heating block 14, which is detachable. During maintenance, the heating block 14 and the hot runner assembly 30 can be disassembled and repaired separately, simplifying maintenance and effectively improving the overall performance. To increase the heating area of ​​the heating block 14 and the hot runner assembly 30, and to assist the hot runner assembly 30 in better preheating, the heating block 14 consists of two sets of annular heating blocks, which are nested together. The mounting grooves 15 are equidistantly located inside the annular heating blocks. A terminal block is provided inside the annular heating block. The hot runner assembly 30 can be heated in a ring shape through the annular heating blocks. During heating, the two sets of annular heating blocks heat the inner and outer sides of the hot runner assembly 30 respectively, resulting in more uniform heating. The hot runner assembly 30 includes a mounting base 31, with a connecting seat 32 at the top and hot runners 33 evenly distributed at the bottom. The mounting base 31 effectively mounts the hot runner 33. A connecting seat 32 connects the mounting base 31 to the feeding seat 13 after installation, allowing material to be fed from the feeding seat 13 through the connecting seat 32 into the hot runner 33. Furthermore, during injection molding, the heating block 14 simultaneously heats the interior of the connecting seat 32, improving the uniformity of heating the molded part. An asbestos board 120 is installed inside the mounting cavity 12, with fixing grooves 121 formed within each groove. The hot runner assembly 30 is installed within these fixing grooves 121.The asbestos board 120 has a through groove 122 inside, and the fixing groove 121 inside the asbestos board 120 can effectively limit the position of the heating block 14. The asbestos board 120 has high heat insulation properties, which can effectively prevent heat loss. The through groove 122 can effectively connect the feeding seat 13 and the connecting seat 32. The cover plate 20 has through holes 21 evenly distributed inside, and the through holes 21 are equipped with heat insulation pipes 22. The bottom of the hot runner assembly 30 is movably inserted into the inside of the heat insulation pipes 22. This design allows the hot runner 33 to extend more effectively, and the insulation pipe 22 effectively insulates the hot runner 33, improving its insulation performance. The bottom of the cover plate 20 has a threaded cavity containing bolts, and the heating base 10 has threaded holes where the bolts are threaded. The threaded cavity effectively conceals the bolts, and the threaded holes ensure proper threading, allowing the cover plate 20 to be better installed at the bottom of the heating base 10.

[0026] Working Principle: During operation, the heating base 10 preheats the hot runner assembly 30, increasing its internal temperature and melting the injection molding compound. The cover plate 20 secures the bottom of the hot runner assembly 30. The heating block 14 is placed within the mounting cavity 12 inside the housing 11. The placement groove 15 effectively defines the position of the hot runner assembly 30, allowing for better placement. Furthermore, the placement groove 15 increases the contact area between the heating block 14 and the hot runner assembly 30, thereby achieving optimal heat dissipation. The device effectively improves the heating speed and uniformity of the hot runner assembly 30 by providing a feeding seat 13, which engages with the upper part of the hot runner assembly 30 to feed material into the hot runner assembly 30. The device also heats the hot runner assembly 30 through a heating block 14, which is detachable. During maintenance, the heating block 14 and the hot runner assembly 30 can be disassembled and repaired separately, improving maintenance convenience and effectively increasing the heating area of ​​the heating block 14 and the hot runner assembly 30, thus assisting the hot runner assembly 30 in better preheating.
