Description

Technical Field

[0001] This utility model relates to a molding die for a water softener base. Background Technology

[0002] A water softener is a device specifically designed to treat domestic water. Its main function is to remove calcium and magnesium ions from the water using ion exchange resin technology, thereby reducing the water hardness. The water softener base is a plastic component of its outer shell structure. Therefore, the production of the water softener base relies on matching molds and injection molding machines.

[0003] Because the water softener base needs to interlock with the top shell, be fixed to the internal mechanism for support, and have various holes for cable routing, its structure contains numerous flanges, cavities, bosses, and holes. Existing water softener base designs are not sufficiently optimized to form these flanges, cavities, bosses, and holes in a single process. Instead, they must be formed in multiple steps, resulting in a cumbersome, time-consuming, and labor-intensive production process with low efficiency. Furthermore, the need for additional molds for secondary forming increases production costs, necessitating further improvements. Utility Model Content

[0043] Working principle:

[0044] The feed plate 1 and the base plate 7 are respectively installed on the actuating mechanism and the machine body of the injection molding machine. The actuating mechanism drives the feed plate 1 to move backward, which in turn drives the moving platen 3 to move towards the fixed platen 5 with the help of the flow divider 2 until the two are joined together, so that the moving core block 4 and the fixed core block 6 fit together (existing technology). At this time, the molding boss 41 extends into the molding cavity 67. During the backward movement of the moving platen 3, it will drive each first traction rod 92 in each side molding mechanism 9, the second traction rod 102 in the upper molding mechanism 10, and the third traction rod 112 in the lower molding mechanism 11 to move backward, which in turn drives the two first sliders 91, the second slider 101, and the third slider 111 to move towards the fixed core block 6. This causes the first forming arc surface 912 on the two first sliders 91, the second forming arc surface 1012 on the second slider 101, and the third arc groove 1113 on the third slider 111 to form a closed loop. At the same time, the circular protrusion 42 extends into the circular concave hole 61, the forming protrusion 62 extends into the forming countersunk hole 43, the square insert 121 on the auxiliary forming block 12 extends into the square countersunk hole 45, the forming protrusion 63 extends into the strip countersunk hole 46, the inner module 131 on the two inserts 13 extends into the two inner mold cavities 47 respectively, the L-shaped baffle 48 extends into the L-shaped groove 65, the rectangular protrusion 49 extends into the rectangular countersunk hole 66, and each arc protrusion 64 extends into a corresponding arc countersunk groove 44.

[0045] Subsequently, the molten material enters the area between the forming boss 41 and the forming cavity 67 through the gate in the feed plate 1 and the runner in the flow divider 2. After cooling, a water softener base is formed (existing technology). Then, the feed plate 1 is driven forward by the action mechanism, and the moving template 3 is driven forward and away from the fixed template 5 by the flow divider 2, so that the moving core block 4 is separated from the fixed core block 6. Then, the formed water softener base is pushed forward by the ejection mechanism 8 (existing technology).

[0046] This invention optimizes the structure, enabling the multiple flanges, cavities, bosses, and holes on the water softener base to be formed in one go, thus eliminating the need for secondary forming. This simplifies the production process, saving time and effort and improving production efficiency. It also eliminates the cost of additional molds required for secondary forming, thereby reducing production costs.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
