Abstract
The utility model discloses a hot runner jet nozzle which saves the manufacturing cost and heats uniformly as well as a special casing pipe spanner matched with same. The hot runner jet nozzle comprises a jet nozzle flange, a jet nozzle main body as well as heating sleeves distributed at the outer periphery of the jet nozzle main body, wherein the jet nozzle flange is in threaded connection with the jet nozzle main body. The hot runner jet nozzle is characterized in that a plurality of slots are formed in the side surface of the jet nozzle main body. The inner wall of the circumference of the special casing pipe spanner matched with the hot runner jet nozzle is provided with slot teeth matched with the slots of the jet nozzle main body; in operation, a thread of the special casing pipe spanner is loosened first, so that the special casing pipe spanner is sleeved into the jet nozzle main body; then the slots and the slot teeth are matched mutually; and then the thread is screwed tightly, so that the special casing pipe spanner is firmly fixed on the jet nozzle main body; and the jet nozzle main body can be mounted and dismounted through screwing a handle, and the spanner is very convenient to use.
Description
Technical field
The utility model relates to a kind of TOP-TIP, particularly a kind of hot-runner nozzle and special sleeve spanner.
Background technology
At present, TOP-TIP obtains widely application in the injection moulding industry.TOP-TIP has the product of shortening molding cycle, saves plastic raw materials, improves the quality of products, and helps the production automation, enlarges advantages such as injection molding process range of application.A kind of common nozzle is made up of nozzle flange, nozzle body and the heating jacket that is distributed in the nozzle body periphery in the TOP-TIP, wherein nozzle flange and nozzle body are by being threaded, the nozzle body upper end has bulge-structure, this bulge-structure is hexagon, and its purpose of design is an interior hexagonal socket wrench loading and unloading nozzle body easy to use.
Adopt above-mentioned bulge-structure to have following deficiency: one, bulge-structure makes heating jacket and nozzle flange apart from increasing, causes melted material in the hot flow path inequality of being heated, and is unfavorable for flowing of melted material; Two, bulge-structure makes that the employed raw material external diameter of this nozzle body of processing is bigger, is unfavorable for economizing on resources, reducing cost, and the wearing and tearing for machining tool in the process are comparatively serious.
The utility model content
The purpose of this utility model is to provide a kind of special sleeve spanner that is used to dismantle of saving the hot-runner nozzle of cost and homogeneous heating and matching.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of hot-runner nozzle, comprise nozzle flange, nozzle body and the heating jacket that is distributed in the nozzle body periphery, wherein nozzle flange and nozzle body are by being threaded, and the nozzle body side has some keyways.Described keyway is uniformly distributed in the middle part of nozzle body side, and the quantity of keyway is at least two and be preferably four, and described keyway all is rounded down, and is convenient to make the key dedentition to go in the keyway like this.
For making things convenient for the loading and unloading of nozzle body, the technical program provides a kind of special sleeve spanner simultaneously, the handle that described special sleeve spanner is semicircular ring by semicircular ring parts and an end is connected through the hinge and forms, the end that described semicircular ring parts and handle are semicircular ring is formed the sleeve of spanner, described sleeve circumferential inner wall be provided with nozzle body on the key tooth that is complementary of keyway.Described sleeve adopts hinge to flexibly connect near an end of handle, and an end relative with hinge adopts screw to fix two parts.During work, unclamp the screw of special sleeve spanner earlier, make special sleeve spanner be inserted in nozzle body, keyway key tooth is cooperatively interacted, screw screw again special sleeve spanner firmly is fixed on the nozzle body, the turn spanner can be realized the loading and unloading of nozzle body.
After adopting above-mentioned keyway design, the close more upper nozzle flange of heating jacket, thus the melted material in the hot flow path is heated evenly, be more conducive to flow.The cancellation of bulge-structure diminishes the blank raw material external diameter of this nozzle of processing, and economical with materials has reduced the wearing and tearing to machining tool more.The design of special sleeve spanner can be loaded and unloaded nozzle body equally easily in addition.
Description of drawings
Fig. 1 is the utility model hot-runner nozzle structural representation.
Fig. 2 is a hot-runner nozzle nozzle body B-B line sectional view shown in Figure 1.
Fig. 3 is the utility model hot-runner nozzle and special sleeve spanner work schematic diagram.
The specific embodiment
Below in conjunction with Figure of description the utility model is made concrete elaboration.
As shown in Figure 1, the utility model patent hot-runner nozzle, comprise nozzle flange 1, nozzle body 2 and the heating jacket 4 that is distributed in the nozzle body periphery, wherein nozzle flange 1 is connected by screw thread 3 with nozzle body 2, as shown in Figure 2, middle part, described nozzle body 2 side has four equally distributed keyways 5, and the keyway bottom is rounded down.
As shown in Figure 3, the semicircular handle 6 that special sleeve spanner is curved by a semicircular feature 7 and an end is connected through the hinge and forms, described special sleeve spanner circumference internal diameter equals the external diameter of nozzle body 2, and circumferential inner wall is provided with four equally distributed key teeth 8, key tooth 8 can cooperatively interact with keyway 5, and an end relative with hinge adopts screw 9 to fix two parts.
During loading and unloading nozzle body 2, screw on the special sleeve spanner 9 is unloaded, make the special sleeve spanner internal diameter become big so that be inserted in nozzle body 2, because keyway is rounded down, four corresponding at an easy rate insertions in four keyways 5 of key tooth 8, screw screw again with special sleeve spanner and nozzle body 2 fixations, use vice attachment to live nozzle flange 1 then, rotary handle can be finished the loading and unloading of nozzle body 2.
