Abstract

The invention provides a good-quality mold for forming ventilating slippers. After mold compounding, the upper ends of vent hole forming columns abut against the lower sides of transverse air hole forming rods, the vent hole forming columns can elastically stretch out and draw back through lower springs to adapt to matching of the self height and the transverse air hole forming rods so that each vent hole forming column can closely abut against the lower portion of the corresponding transverse air hole forming rod, and then it is ensured that vent holes and transverse air holes in the bottoms of the slippers obtained after material injection and forming are communicated. Clamping head steps and clamping stop steps are matched so that the vent hole forming columns can be prevented from being separated out of through holes. The vent hole forming columns can be further matched with and closely attached to the transverse air hole forming rods through arc-shaped end grooves, and even slight position deviation exists, the vent hole forming columns can be incidentally combined with the outer circumference faces of the transverse air hole forming rods through the arc-shaped end grooves in a clamped manner, and abutting is more accurate. In addition, plug screws can be rotated to adjust the telescopic degree of the vent hole forming columns according to actual needs.

Example Embodiment

[0019] In order to further explain the technical solution of the present invention, specific embodiments are used to describe in detail below.
[0020] The mold of the present invention for forming ventilated and breathable slippers with good quality, such as figure 1 with 2 As shown, it includes an upper mold plate 1 with an upper mold cavity, a lower mold plate 2 with a lower mold cavity, a shoe last mold core 3 arranged between the upper mold 1 and the lower mold 2, and a shoe last mold The horizontal air hole template 4 between the core 3 and the upper template 1.
[0021] The rear edge of the shoe last mold core 3 is hinged to the lower template 2, and the rear edge of the upper template 1 is hinged to the shoe last mold core 3. The upper surface of the shoe last mold core 3 is evenly distributed with multiple rows of parallel vents to form columns 31. The horizontal air hole template 4 includes a left template and a right template that are spliced ​​together left and right. The left template and the right template are opened and closed around the back side along the center, and the closed openings of the left template and the right template are respectively provided with a sole-shaped arc The left template and the right template are closed to form a sole-shaped mold cavity. The inner side of the left template and the right template are provided with corresponding horizontal vent forming rods 41; the vent forming column 31 corresponds to the horizontal vent forming rod Below 41; the shoe last-shaped core 3 is formed with a plurality of through holes 32 for each vent hole forming column 31 to match sliding and expansion one by one. The lower end of the through hole 32 is blocked with a removable plugging screw 5, the through hole The lower end of 32 is formed with an internal thread that matches the external thread of the plugging screw 5, and the through hole 32 is provided with a spring 6 stretched between the lower end of the vent forming column 31 and the upper end of the blocking screw 5; the vent forming column The lower end of 31 is formed with a chuck step 311, and the upper end of the through hole 32 is formed with a locking step 321 for clamping the chuck step 311; the upper end of the vent forming column 31 is formed with an arc matching the peripheral surface of the horizontal vent forming rod 41 形端槽310。 Shaped end slot 310. In the actual working process of the present invention, when the mold is closed, the upper end of the vent forming column 31 will abut the lower side of the horizontal vent forming rod 41, and the vent forming column 31 can rely on the spring 6 below to elastically expand and contract to adapt to The height of itself is matched with the horizontal vent forming rod 41, so that each vent forming column 31 can tightly press under the corresponding horizontal vent forming rod 41, thereby ensuring that the vents and horizontal holes at the bottom of the slippers after injection and molding The air holes are connected, which overcomes the defect that the air holes and horizontal air holes formed by traditional shoe molds are often unable to communicate and cannot achieve the purpose of ventilation. Moreover, the cooperation of the clamping head step 311 and the locking step 321 can prevent the air hole from forming the pillar 31 from the through hole 32. The vent hole forming column 31 can be further matched and closely fitted by the arc-shaped end groove 310 and the horizontal air hole forming rod 41, and even if there is a small position deviation, the outer peripheral surface of the rod 41 can be formed by the arc-shaped end groove 310 and the horizontal air hole. It can be snapped together to make the topping more accurate, and the degree of expansion and contraction of the vent forming column 31 can be adjusted by rotating the plugging screw 5 according to actual requirements. The specific structure may be that a bayonet (not shown in the figure) is formed at the lower end of the plugging screw 5 for rotation.
[0022] Preferably, the outer diameter of the chuck step 311 corresponds to the inner diameter of the through hole 32. This structure can ensure that the chuck step 311 will not shake in the through hole 32 and ensure the stability and linearity of the expansion and contraction of the ventilation hole forming column 31 in the through hole 32.
[0023] Preferably, the outer diameter of the spring 6 corresponds to the diameter of the through hole 32 and the plugging screw 5. This structure can ensure that the spring 6 will not sway in the through hole 32 and ensure the stability and linearity of the expansion and contraction of the vent forming column 31 in the through hole 32.
[0024] Preferably, the through holes 32 are arranged along the horizontal air hole forming rod 41. This structure can ensure that the vent forming posts 31 are arranged neatly and regularly, and they all correspond to the corresponding horizontal vent forming rods 41.
[0025] In the mold for forming ventilated and ventilated slippers of the present invention, the specific form and size of the clamping head step and the blocking step can be adjusted and designed according to actual requirements; the plugging screw, through hole, spring and ventilation hole form the specific column The form, size, quantity, setting position and distribution form can be adjusted and designed according to actual requirements. For example, the plugging screw can be gradually lengthened according to the thickness of the last-shaped core, or the length of the spring can be adjusted according to the thickness of the last-shaped core. The thickness gradually becomes longer; the specific form, size, number, setting position and distribution form of the horizontal air hole forming rod can be adjusted and designed according to actual requirements; the overall structure of the upper template, the lower template, the shoe last mold core and the horizontal air hole template It is preferably an existing structure, but it can be adapted to the technical solution of the present invention.
[0026] The product form of the present invention is not limited to the illustrations and examples in this case. Anyone who makes appropriate changes or modifications of similar ideas should be regarded as not departing from the patent scope of the present invention.
