TECHNICAL FIELD
[0001] The present application relates to the technical field of equipment mold, in particular to a general mold for injection molding machine. BACKGROUND
[0002] At the present stage of rapid development of injection molded products, the demand for materials, colors, shapes, etc. of plastic parts is becoming higher and higher. There are more products with double colors, three colors and other multi-color products.
[0003] The three-color injection molding machine has A, B and C three feed nozzles, which respectively fill plastic particles of different colors or different materials. The three feed nozzles of the injection molding machine correspond to three feed screws, and the screws need to be matched with the filled plastic particles. For example: the screw corresponding to the A feed nozzle 6 is used for filling PC transparent material, and this screw cannot be replaced by other materials or other colors of materials for injection molding. Therefore, in order to meet the injection molding needs of different products, injection molding machines matching the corresponding injection molding sequence need to be purchased. Special machine matching is easy to cause resource waste and cost increase.
[0004] The three-color PC material injection molding machine of our company basically fills PC black 9 with A feed nozzle 5, fills PC transparent color 8 with B feed nozzle 6, and fills PC milk white color 10 with C feed nozzle 7. The product is arranged vertically in the mold, the first cavity B feed nozzle and the C feed nozzle are filled, the movable mold is rotated by 180°, and then the second cavity A feed nozzle is filled; three-color injection filling is completed. A new project needs to fill B feed nozzle PC transparent color first, and then the movable mold is rotated by 180°, and the second cavity is filled with A feed nozzle and C feed nozzle to fill and inject black and milk white.
[0005] Because the C feed nozzle is on the operating side of the injection molding machine, there are the following two problems: 1. The length of the hot runner distribution plate needs to be lengthened to the second cavity position for filling, the span is relatively long, which causes more plastic particles to be stored in the hot runner, the storage time in the hot runner system is relatively long, and there is a risk of degradation, which causes the product to have poor strength and cracking risk; 2. The hot runner distribution plate has a long span, and there are three hot runner systems in the mold, which cannot effectively meet the installation and fixation of the hot runner system of the C feed nozzle. If the injection molding is carried out according to the filling sequence of this part, a matching machine needs to be purchased, and the cost needs to be greatly increased.
[0006] Therefore, it is necessary to design a general mold for injection molding machine to meet the actual application needs. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0034] Referring to Figs. 1-3 , the injection molding machine general mold of the specific embodiment of the present application comprises an injection molding mechanism 1, a flow channel structure 2 and a feeding nozzle 3, the feeding nozzle 3 is arranged at the feeding port of the flow channel structure 2, the flow channel structure 2 is connected with the injection molding mechanism 1, so as to be capable of respectively injecting products via the injection molding mechanism 1, the flow channel structure 2 at least comprises a first flow channel 21, a second flow channel 22 and a third flow channel 23, and the third flow channel 23 is adapted to be connected with the injection molding mechanism 1 across the second flow channel 22, so as to be capable of shortening the distance between the third flow channel 23 and the corresponding injection molding mechanism 1.
[0035] Specifically, the injection molding mechanism 1 at least comprises a first injection molding machine 11, a second injection molding machine 12 and a third injection molding machine 13, wherein the first injection molding machine 11 is arranged corresponding to the first flow channel 21, the second injection molding machine 12 is arranged corresponding to the second flow channel 22, and the third injection molding machine 13 is arranged corresponding to the third flow channel 23, wherein the first injection molding machine 11, the second injection molding machine 12 and the third injection molding machine 13 are adapted to be arranged along the flow direction of the products, that is, the products are arranged transversely in the mold, and the products are respectively injected and filled by the first injection molding machine 11, the second injection molding machine 12 and the third injection molding machine 13. It should be noted that the transverse direction here represents the arrangement direction of the injection molding mechanism 1, and the longitudinal direction represents the arrangement direction across multiple injection molding machines.
[0036] More specifically, one end of the first flow channel 21 is connected with the first injection molding machine 11, the other end of the first flow channel 21 is connected with the first feeding nozzle 31, one end of the second flow channel 22 is connected with the second injection molding machine 12, the other end of the second flow channel 22 is connected with the second feeding nozzle 32, one end of the third flow channel 23 is connected with the third injection molding machine 13, the other end of the third flow channel 23 is connected with the third feeding nozzle 33. And the first feeding nozzle 31 is suitable for injection molding transparent color rubber to form transparent product 4, the second feeding nozzle 32 is suitable for injection molding black color rubber to form black product 5, the third feeding nozzle 33 is suitable for injection molding milky white color rubber to form white product 6. When the product is injection molded and filled, the product is first injection molded and filled by the second injection molding machine 12 and the third injection molding machine 13, and then the product is rotated by 180° after the product mold is rotated by 180°, and then the first injection molding machine 11 is used to fill and injection mold the product rotated by 180°, so as to complete the three-color injection molding and filling of the product.
[0037] Referring to Fig. 1 , the injection molding mechanism 1 further comprises an injection molding platform 14, wherein the first feeding nozzle 31 and the second feeding nozzle 32 are arranged on the top of the injection molding platform 14, and the third feeding nozzle 33 is arranged on the side of the injection molding platform 14, so as to simultaneously injection mold and fill the product through the third feeding nozzle 33 and the second feeding nozzle 32 and the second flow channel 22 and the third flow channel 23 connected therewith. Therefore, the third flow channel 23 connected with the third feeding nozzle 33 can be arranged around the outside of the second injection molding machine 12 and the third injection molding machine 13, so as to fix the third flow channel 23 and the third feeding nozzle 33. At the same time, the third flow channel 23 is detachably arranged on the side of the injection molding platform 14, and a plurality of mounting holes are arranged on the injection molding platform 14, so that when the third flow channel 23 is installed, the plurality of mounting holes can be used to position the installation position of the third flow channel 23, so as to facilitate the installation and disassembly of the third flow channel 23.
[0038] Specifically, the first feeding nozzle 31 and the second feeding nozzle 32 are arranged between the first injection molding machine 11 and the second injection molding machine 12, and the second flow channel 22 connected with the second feeding nozzle 32 is arranged obliquely between the plurality of second injection molding machines 12, so as to shorten the injection molding distance of the second feeding nozzle 32 to the plurality of second injection molding machines 12.
[0039] More specifically, in order to further improve the injection molding speed of the first feeding nozzle 31 to the first injection molding machine 11 and reduce the flow time of the rubber in the feeding pipe, the first injection molding machines 11 are first connected by independent flow channels, then the plurality of flow channels connected by the independent flow channels are converged into one flow channel, and the converged flow channel is connected with the first feeding nozzle 31, so as to reduce the distance of the first flow channel 21 to each first feeding nozzle 31 and also play a role of flow distribution.
[0040] In addition, in order to avoid the third flow channel 23 from interfering with the second flow channel 22 or the first flow channel 21 after being arranged, the third flow channel 23 is arranged above the second flow channel 22, so that the third flow channel 23 can communicate with the third feeding nozzle 33 after crossing the second flow channel 22. At the same time, since the third flow channel 23 only needs to cross the second flow channel 22 to communicate with the third feeding nozzle 33, compared with the traditional structure design of crossing the first flow channel 21 and the second flow channel 22, the distance of the rubber material flowing in the third flow channel 23 is greatly reduced, and the problem of degradation of the material flowing therein due to long span is avoided. At the same time, since the arrangement of the third flow channel 23 does not interfere with the second flow channel 22 and the first flow channel 21, the third flow channel 23 can be conveniently and quickly positioned and disassembled, without the need to purchase a new matching machine, and can be easily replaced to adapt to different materials flowing therein.
