DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 The injection core-pulling mold for the internal water channel structure of the water outlet device in this embodiment includes a fixed mold 1, a movable mold 2 is provided on the upper side of the fixed mold 1, a gate 3 is opened at the center of the upper surface of the movable mold 2, a molding mechanism 4 for facilitating the molding of the water separation structure is provided on the right side of the fixed mold 1, and a core-pulling mechanism 5 for facilitating core pulling is provided at the left end of the inner bottom wall of the fixed mold 1.

[0029] In this embodiment, a positioning plate 6 is fixed to the middle of the inner bottom wall of the fixed mold 1, and a molding cavity 7 is provided on the upper surface of the positioning plate 6. The shape of the fixed mold 1 is a rectangular parallelepiped with a hollow interior and partially missing left and right sides.

[0030] See also Figures 2 to 3In order to enable the water outlet device to be quickly injection molded, the molding mechanism 4 in this embodiment includes a fixed plate 41, a cylinder 42, a drive motor 43, a moving block 44, three rotating rods 45, three rotating gears 46 and two core-pulling molds 47. The fixed plate 41 is fixed to the right side of the fixed mold 1, the cylinder 42 is fixed to the top of the right side of the fixed plate 41, and the drive motor 43 is fixed to the bottom of the right side of the fixed plate 41. The piston rod of the cylinder 42 penetrates the fixed plate 41 and extends to the inner cavity of the fixed mold 1 and is fixed to the moving block 44. The cylinder 42 can be started, and the piston rod of the cylinder 42 is shortened, thereby driving the moving block 44 to move to the right, and the rotating rod 4 The rotating gear 46 is fixed on the outer surface of the rotating rod 45, and the driving motor 43 is started. The output shaft of the driving motor 43 rotates to drive the lower rotating rod 45 to rotate, so that the rotating gear 46 fixed on the outer surface of the lower rotating rod 45 rotates. The rotation of the lower rotating gear 46 causes the upper rotating gear 46 meshing with it to rotate. The rotation of the upper front rotating gear 46 drives the upper rear rotating gear 46 meshing with it to rotate. The core-pulling mold 47 is fixed on the left side of the rotating rod 45. The rotation of the two upper rotating gears 46 drives the core-pulling mold 47 to rotate.

[0031] In this embodiment, the output shaft of the driving motor 43 passes through the fixed plate 41 and extends to the inner cavity of the fixed mold 1 and is fixed to the rotating rod 45. The lower rotating gear 46 is meshedly connected with the rotating gear 46 at the front end of the upper side, and the two rotating gears 46 at the upper end are meshedly connected.

[0032] Among them, positioning blocks are fixed on the opposite sides of the front and rear side walls of the inner cavity of the fixed mold 1, and sliding grooves are opened on the top and bottom of the opposite sides of the two positioning blocks. Slide blocks are fixed on the upper and lower ends of the front and rear sides of the moving block 44, and the slide blocks make horizontal linear motion in the inner cavity of the sliding groove. The slide blocks fixed on the front and rear sides of the moving block 44 move to the right in the inner cavity of the sliding groove, which can limit the movement of the moving block 44.

[0033] It should be noted that the movement of the moving block 44 drives the core pulling mold 47 to move to the right, so that the core pulling mold 47 moves out of the inner cavity of the molding mold, thereby achieving the effect of driving the core pulling mold 47 to spirally withdraw, so as to avoid damage to the molded threaded structure, and can quickly injection mold the water outlet equipment, reducing the labor intensity of the staff.

[0034] See also Figure 4 In order to achieve the core pulling effect, the core pulling mechanism 5 in this embodiment includes a sliding seat 51 and a guide rod 52. The sliding seat 51 is arranged at the left end of the inner bottom wall of the fixed mold 1. A mounting hole 53 is opened on the top of the sliding seat 51. The guide rod 52 is fixed in the inner cavity of the mounting hole 53. The movement of the guide rod 52 can drive the movement of the movable mold 2, so that the movement of the guide rod 52 drives the sliding seat 51 to move left or right.

[0035] In this embodiment, the angle between the guide rod 52 and the right end of the top of the sliding seat 51 is an acute angle, the top and bottom of the opposite side of the front and rear side walls of the inner cavity of the fixed mold 1 are fixed with limit rods, and the top and bottom of the sliding seat 51 are fixed with limit sleeves, and the limit sleeves are slidably connected to the limit rods.

[0036] It should be noted that when the guide rod 52 moves toward or away from the fixed mold 1 , it will drive the sliding seat 51 to move horizontally, thereby achieving a core pulling effect.

[0037] The working principle of the above embodiment is:

[0038] After the water outlet device is injection molded, the drive motor 43 is first started. The output shaft of the drive motor 43 rotates to drive the lower rotating rod 45, thereby causing the rotating gear 46 fixed on the outer surface of the lower rotating rod 45 to rotate. The rotation of the lower rotating gear 46 causes the upper rotating gear 46 meshing with it to rotate. The rotation of the upper front rotating gear 46 drives the upper rear rotating gear 46 meshing with it to rotate. The rotation of the two upper rotating gears 46 drives the core-pulling mold 47 to rotate. At this time, the cylinder 42 can be started, and the piston rod of the cylinder 42 is shortened, thereby driving the moving block 44 to move rightward. At this time, the sliders fixed on the front and rear sides of the moving block 44 move to the right in the inner cavity of the slide groove, which can limit the movement of the moving block 44 and drive the core pulling mold 47 to move to the right, so that the core pulling mold 47 moves out of the inner cavity of the forming mold, thereby achieving the effect of driving the core pulling mold 47 to spirally withdraw, so as to avoid damage to the formed threaded structure; the movement of the movable mold 2 can drive the movement of the guide rod 52, so that the movement of the guide rod 52 drives the sliding seat 51 to move left or right. When the guide rod 52 moves toward or away from the fixed mold 1, it will drive the sliding seat 51 to move horizontally, so as to achieve the effect of core pulling.
