Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 to 5, the semi-thermal multi-cavity dripper mold of this embodiment includes two mold plates 1 disposed opposite to each other, a mold frame 11 is disposed on each mold plate 1, at least one mold core 2 is disposed in each mold frame 11, at least one main runner 21 and a plurality of branch runners 22 are disposed on each mold core 2, each branch runner 22 is connected to the main runner 21, mold cavity grooves 23 are disposed on two sides of each branch runner 22, gates 24 communicating with the mold cavity grooves 23 are disposed on the branch runners 22, and the calibers of the gates 24 are gradually reduced along a flowing direction. The heat flow channel plate 3, the mounting plate 4, the ejector pins 5, and other components that are configured conventionally may be included, but are not limited herein.
Specifically, in the semi-hot multi-cavity dripper mold of the embodiment, the corresponding mold cores 2 are installed on the two mold plates 1 through the mold frame 11, the mold cores 2 form corresponding injection molding cavity grooves 23 according to drippers to be injected, during the injection molding process, the two mold plates 1 are tightly attached together, so that the corresponding two mold cores 2 are attached together, correspondingly, an injection molding cavity is formed between the two cavity grooves 23, the corresponding main runners 21 are attached together, and the corresponding sub runners 22 are attached together. In the injection molding process, the injection molding material output by the injection molding machine enters the main runner 21 and is supplied to the two corresponding injection molding cavities through the sub-runner 22, and the caliber of the sprue 24 between the sub-runner 22 and the cavity groove 23 is gradually reduced along with the flow direction of the injection molding material, so that the injection molding material output from the sprue 24 forms larger pressure and accelerates the flow rate of the injection molding material entering the injection molding cavities, the whole injection molding cavities can be quickly filled with the injection molding material, the phenomenon of poor flowability caused by hardening of the injection molding material due to overlong injection molding time is reduced, in addition, the injection molding material injected into the injection molding cavities can be quickly filled, the injection time is effectively shortened, the internal stress of drippers formed by injection molding is reduced, and the product quality of the drippers is improved. In order to facilitate the injection of the injection molding material, the mold core 2 of one of the mold plates 1 is provided with a material injection through hole 20 communicating with the main runner 21, and the mold core 2 of the other mold plate 1 is not required to be provided with the material injection through hole 20.
Further, the sprue 24 is arranged at the free end of the sub-runner 22, and in order to ensure smooth and rapid flow of the injection molding material, the cross sections of the main runner 21 and the sub-runner 22 are semicircular, so that the flow resistance of the injection molding material can be effectively reduced by the semicircular main runner 21 and the semicircular sub-runner 22, and the temperature drop amplitude of the injection molding material in the flowing process is reduced. Preferably, in order to ensure that the injection molding material at the gate 24 is sufficiently supplied, a groove structure 221 is formed in the runner 22 near the gate 24, and specifically, the runner 22 stores enough injection molding material in the groove structure 221, so that when the injection molding material is injected into the gate 24, enough injection molding material can be ensured to enter the gate 24, and each injection molding cavity can be uniformly filled with the injection molding material.
Furthermore, in order to improve the quality of the injection-molded dripper, an insert groove (not labeled) penetrating through the cavity groove 23 is formed in the mold core 2, an insert 25 is disposed in the insert groove, and a molding protrusion 251 is disposed at an end of the insert 25 located in the cavity groove 23. Specifically, because the dripper needs to be injection-molded to form a turbulent flow channel with a toothed structure, correspondingly, the cavity groove 23 needs to be provided with a model contour for forming the turbulent flow channel, and because the structure size is very small, the processing difficulty of directly processing the convex model contour on the cavity groove 23 of the die core 2 is high, and by adopting the mode of the insert 25, the convex structure 251 on the insert 25 is correspondingly designed according to the processed dripper, and the processing amount of the convex part in the cavity groove 23 is small, on one hand, the die core 2 is easier to process to reduce the processing difficulty, on the other hand, the convex structure 251 formed on the insert 25 is easier to process and has high processing precision, and after the insert 25 is inserted into the insert groove, the convex structure 251 is positioned in the cavity groove 23, so that a dripper with higher quality can be formed in the injection molding process. The protruding structure on the insert 25 may be formed by high-precision machining methods such as wire cutting, electric discharge machining, and numerical control milling, which are not limited in this embodiment.
Compared with the prior art, the utility model discloses an advantage is with positive effect: through setting up the die cavity groove respectively in the both sides of subchannel, and set up the runner into the bell mouth, in the actual in-process of moulding plastics, two templates paste and lean on together, make two relative die cavity groove form the die cavity of moulding plastics, the injection molding material flows into each subchannel through the sprue, and when rethread runner entered into the die cavity groove, because the aperture of both ends mouth diminishes gradually around the runner, make the injection molding material of following the runner output form great pressure, reduce the surface viscosity of injection molding material, make the injection molding material be full of the die cavity of moulding plastics fast, with the input speed in balanced each chamber, ensure that each injection molding cavity is filled with the material, realize improving the yield of half hot many chamber emitter mould. Meanwhile, as the injection molding material injected into the injection molding cavity can be filled quickly, the time for injecting the injection molding material is effectively shortened, the internal stress of the dripper formed by injection molding is reduced, and the product quality of the dripper is improved.
