Abstract
The invention discloses an injection molding mold for an inner plug of a perfume bottle cap. The injection molding mold comprises a male mold and a female mold, wherein the male mold comprises a cylindrical mold head, a cylindrical mold cavity is arranged on the female mold, an injection molding hole communicated with the mold cavity is arranged on the female mold, a positioning bulge is arranged at the end part of the mold head of the male mold, the positioning bulge is coaxial with the male mold, and a positioning cavity corresponding to the positioning bulge is arranged in the female mold. The injection molding mold for the inner plug of the perfume bottle cap can uniformly mold the inner plug of the perfume bottle cap.
Description
Technical field
The present invention relates to injection forming mold, be meant plug injection forming mold in a kind of perfume bottle cap especially.
Background technology
The plug injection forming mold comprises punch and die in the present perfume bottle cap, and wherein punch comprises a columned die head, and die is provided with a columned die cavity; Die is provided with the injecting hole that is communicated with die cavity, and during work, die head is inserted in the die cavity; The plastics of fusion inject from the injecting hole high pressure then, because the gap of plug in the moulding is arranged between the die cavity of die head and die, so the cooperation between die head and the die is a matched in clearance; Like this, the plastics that high pressure injects can produce downward impulsive force to die head, cause the axiality of die head and die cavity to reduce; Die head downward bias leaves during moulding, and the interior plug of moulding tends to occur the phenomenon of wall unevenness.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of can be so that plug injection forming mold in the perfume bottle cap of plug uniform in shaping in the scent flask lid.
For solving the problems of the technologies described above, technical scheme of the present invention is: plug injection forming mold in the perfume bottle cap comprises punch and die; Said punch comprises columned die head; Said die is provided with a columned die cavity, and die is provided with the injecting hole that is connected with die cavity, and the die head end of said punch is provided with locator protrusions; Said locator protrusions is coaxial with punch, and said die inside is provided with and the corresponding positioning chamber of locator protrusions.
As a kind of preferred scheme, said locator protrusions is cylindrical.
As a kind of preferred scheme, said locator protrusions is a truncated cone.
After having adopted technique scheme, effect of the present invention is: because the plug injection forming mold is provided with locator protrusions in the die head end of punch in this perfume bottle cap, said locator protrusions is coaxial with punch; Said die inside is provided with and the corresponding positioning chamber of locator protrusions; After locator protrusions extend in the die cavity, when the impacting with high pressure die head of injection moulding, locator protrusions was located in positioning chamber; Thereby guarantee that the die head axis can not depart from, reach plug wall thickness effect of uniform in the perfume bottle cap after the moulding.

The specific embodiment
Through specific embodiment plug injection forming mold in the perfume bottle cap of the present invention is done further to describe in detail below.
Embodiment 1
As shown in Figure 2, the plug injection forming mold comprises punch 1 and die 2 in the perfume bottle cap; Said punch 1 comprises columned die head 11; Said die 2 is provided with a columned die cavity, and die 2 is provided with the injecting hole 21 that is connected with die cavity, and die head 11 ends of said punch 1 are provided with locator protrusions 12; Said locator protrusions 12 is coaxial with punch 1, and said die 2 inside are provided with and locator protrusions 12 corresponding positioning chambers 22.Locator protrusions described in the present embodiment 12 is a truncated cone.
During work; After the locator protrusions 12 of punch 1 extend in the positioning chamber 22 of die 2; When injection moulding liquid got into die 2 die cavitys through injecting hole 21, impacting with high pressure die head 11 was because locator protrusions 12 is located in positioning chamber 22; Thereby guarantee that die head 11 axis can not depart from injection moulding process, the plug wall thickness is even in the perfume bottle cap after the moulding.
Embodiment 2
As shown in Figure 3, in the present embodiment, said locator protrusions 12 is cylindrical.The shape of removing locator protrusions 12 is different with embodiment 1, and other are all identical with embodiment 1.
Claims (3)
1. fill in injection forming mold in the perfume bottle cap; Comprise punch and die, said punch comprises columned die head, and said die is provided with a columned die cavity; Die is provided with the injecting hole that is connected with die cavity; It is characterized in that: the die head end of said punch is provided with locator protrusions, and said locator protrusions is coaxial with punch, and said die inside is provided with and the corresponding positioning chamber of locator protrusions.
2. fill in injection forming mold in the perfume bottle cap according to claim 1, it is characterized in that: said locator protrusions is cylindrical.
