Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1 to 2, the hollow pressure-bearing water channel provided in the present embodiment includes a connecting portion 2 and a hollow water channel 1. The hollow water channel 1 is internally provided with a through hole convenient for water circulation. The connecting part 2 is arranged at the end part of the hollow waterway 1. The connecting part 2 is connected with the hollow water channel 1 in a mode of being formed at the end part of the hollow water channel 1 through independent injection molding. When the hollow pressure-bearing water channel is manufactured, firstly, the hollow water channel 1 is manufactured through injection molding (each hollow water channel 1 is divided into an upper part and a lower part, the two parts are respectively injected, then the two parts are welded in an ultrasonic welding mode to form the hollow water channel 1), then, the hollow water channel 1 formed through injection molding is placed into a mold for secondary injection molding, connecting portion 2 is moulded plastics out at cavity water course 1 tip, through the direct parcel of melting plastics on the surface of cavity water course 1 (the surface of cavity water course 1 and connecting portion 2 hookup location, through the plastic material who changes cavity water course 1, make the melting point of cavity water course 1 be higher than the melting point of connecting portion 2, make when moulding plastics connecting portion 2, the heat of moulding plastics only can produce less deformation to cavity water course 1, the realization is connected cavity water course 1 connecting portion 2, on being connected to connecting portion 2 with cavity water course 1 again when moulding plastics connecting portion 2. Compare in traditional manufacturing approach and mould plastics out back with connecting portion 2 and be connected to connecting portion 2 with cavity water course 1 again, the utility model discloses a hollow pressure-bearing water course has avoided the step with the two joint, improves the efficiency of the hollow pressure-bearing water course of production preparation, adopts direct parcel cavity water course 1 of molten plastics to reach simultaneously and compare the mode of being connected connecting portion 2 and cavity water course 1 and have more strengthened seal and intensity in adopting the welding to compare the mode of being connected connecting portion 2 and cavity water course 1, so the hollow pressure-bearing water course that this embodiment is disclosed has and does not need extra sealing, the amalgamation step, and the leakproofness is good, the advantage that intensity is high.
Further, because the hollow water channel 1 has a complex structure, the hollow water channel 1 internally comprises a through-hole water channel and cannot be manufactured by single injection molding, the hollow water channel 1 can be divided into two parts, the two parts are respectively subjected to injection molding, and then ultrasonic welding is carried out (the ultrasonic welding is to convert 50/60 Hz current into 15, 20, 30 or 40KHz electric energy through an ultrasonic generator, the converted high-frequency electric energy is converted into mechanical motion with the same frequency again through a transducer, and then the mechanical motion is transmitted to a welding head through a set of amplitude transformer device capable of changing amplitude.
In order to reduce the influence on the shape structure of the hollow waterway 1 when the connecting part 2 is injection molded, the melting temperature of the connecting part 2 is further slightly lower than the softening temperature of the hollow waterway 1. For example, when the hollow water channel 1 is made of polyvinyl chloride (PVC) with a melting point of 150-200 ℃, the material of the connecting portion 2 can be made of 150 ℃ polyester resin (UP) with a melting point of 140-.
In order to make the connection between the hollow waterway 1 and the connection portion 2 more tight, further, the outer surface of the hollow waterway 1 is textured. The line face has some unevenness's structure for the surface, when cavity water course 1 was connected with connecting portion 2 injection moulding, the pit in the line face on the surface of cavity water course 1 can be entered into to the molten plastics, treats plastics cooling solidification back, both can make connecting portion 2 and cavity water course 1 between be connected more firmly.
Example two:
as shown in fig. 3, the mold for manufacturing the hollow water channel provided in this embodiment includes a movable mold, a fixed mold 4, and a hollow water channel accommodating groove 5. The fixed die 4 is matched with the movable die, an injection molding cavity is formed between the fixed die and the movable die, and the injection molding cavity is the structure of the connecting part 2. The hollow water channel accommodating groove 5 is formed in the matched surface of the movable mold and the fixed mold 4 and communicated with the injection molding cavity, so that when the connecting portion 2 is subjected to injection molding, the hollow water channel 1 is located in the mold and is in contact with the connecting portion 2, and the connecting portion 2 is subjected to injection molding and connected with the hollow water channel 1. When connecting portion 2 need be moulded plastics, arrange cavity water course 1 in cavity water course holding tank 5 earlier, fixed cavity water course 1, then pour into the molten plastics to the type of moulding plastics intracavity and fill the type, treat the plastics cooling back, both can make cavity water course 1 and connecting portion 2 combine.
Further, the mold for manufacturing the hollow pressure bearing water channel further comprises a glue sealing positioning device 6 (a positioning block fixed on the fixed mold 4), and the glue sealing positioning device 6 is arranged at the tail part of the hollow water channel 1, which is far away from the connecting part 2, and is used for positioning the hollow water channel 1 on the mold. The position of the hollow water channel 1 is positioned by the glue sealing positioning device 6 so as to facilitate the position alignment between the hollow water channel 1 and the connecting part 2.
Further, when cavity water course 1 was located the mould, its inlet outlet closely laminated with the core 7 in the injection molding die cavity, and the molten plastic enters into cavity water course 1 and makes cavity water course 1 and the inside cavity intercommunication of connecting portion 2 when avoiding moulding plastics connecting portion 2. When the hollow water channel 1 is arranged in the mold, the water channel through hole at the connecting end of the hollow water channel 1 and the connecting part 2 is tightly attached to the mold core 7 in the injection molding cavity, the water channel through hole is blocked by the mold core 7, and the phenomenon that the molten plastic in the injection molding cavity enters the hollow water channel 1 to cause the internal blockage of the hollow water channel 1 is avoided.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
