Problems solved by technology
[0003] However, this process also has the following disadvantages. First, because the inner core of the main body is manually placed into the molding cavity of the mold core, workers may make mistakes and fail to align the positioning convex 11' with the positioning concave hole on the molding cavity. During the secondary punching, if the positioning convex 11' is not inserted into the positioning concave hole, the position of the main body inner core 1' is actually offset, which makes the main body inner core 1' and the secondary overmolding There may be a certain gap between the layers 2'; in addition, if the mold temperature is not enough or the temperature of the rubber is not enough, the formed secondary plastic coating layer 2' may not be completely compliant with the surface layer of the main body inner core 1', and A gap is generated; at this time, because there is a gap (gap) between the main body inner core and the secondary plastic coating layer 2', once the faucet after the second injection molding leaks at the junction, it is easy to leak from the main body inner core 1' and the secondary plastic coating layer 2'. Seep into the gap (gap) between the secondary plastic coating layer 2', and then further seep out of the secondary plastic coating layer 2' from the side wall and the positioning bumps (11', 13') below, resulting in the product being in use water leaking in process

Embodiment
[0045] Such as Figure 3-4 As shown, a faucet plastic water channel integrated structure, including the main body inner core 1, secondary injection molding layer 2, copper pins 3 on the left and right sides, is characterized in that: the main body inner core 1 is a through pipe, the main body inner core 1 The incisions on both sides present an inward arc-shaped incision 12, and a through hole 13 vertically penetrating through the main body inner core 1 is provided in the middle; Two spool accommodating cavities 21 communicating with the inner core 1 of the main body and intermediate water passages 211 respectively communicating with the two spool accommodating cavities 21 are respectively formed at In the copper pins 3 on both sides, the secondary injection molding layer 2 further forms an upper water outlet 22 and a lower water outlet 23 on the vertically penetrating through hole 13 in the middle of the main body inner core 1, and the upper water outlet 22 is higher than the ...

The invention relates to a faucet plastic waterway integrated structure and a molding die and method thereof. Rationalized design is used for enabling a main body inner core to obtain four-aspect fixing force in a complete die cavity of the molding die, so that the main body inner core is stably clamped below upper and lower sliders to be free of falling, no offset is generated within the completedie cavity, and molding results can be completely achieved according to the established shape; and structures such as a positioning structure, a limiting structure and positioning convex particles related in the background technology do not needed to be arranged on the main body inner core any more, a waterway completely achieves paving in the main body inner core and a secondary injection layer,and leakage is not generated any more.
Description
technical field [0001] The invention relates to the field of sanitary ware, in particular to a faucet plastic waterway integrated structure, a forming mold and a forming method thereof. Background technique [0002] As shown in Figure 1-2, the existing copper-clad plastic secondary injection molding faucets generally have multiple positioning and limiting structures on the main body inner core 1', mainly including the side wall positioning bumps 11', In order to put the main body inner core 1' (water channel inner core) into the molding cavity of the rear mold core, the positioning convex 11' can cooperate with the positioning concave hole at the corresponding position on the molding cavity of the rear mold core, so that the main body inner core 1 When putting into the mold, the preliminary positioning in the molding cavity is realized by giving the positioning convex 11'; a water outlet 12' is provided above the main body inner core 1', and the water outlet 12' generally pr...
