Abstract
The invention discloses a converting structure for forming two plastic products in one set of injection molding die. According to the converting structure, the problems in the prior art can be solved and the reliability of converting adjustment is further ensured. The converting structure comprises male die holders, female dies and male die cores, wherein die cavities are formed by enclosing of the female dies and the male die cores; the die cavities are respectively independent; inlets of various independent die cavities are communicated with a runner through adjusting inserts; the runner with a circular section is arranged at the lower parts of the adjusting inserts; and the adjusting inserts are clamped in rotating inserts. The converting structure is characterized in that a bottom end surface of each rotating insert is set into a plum blossom shape; a plum blossom groove is formed corresponding to the bottom of each rotating insert; and the bottom of each rotating insert is clamped in the plum blossom groove.
Description
?
Technical field
The present invention relates to the injection mould technical field of mold, be specially the transferring structure of two kinds of plastic cement products of moulding in the cover injection mold.
Background technology
In the existing injection mold, for saving the manufacturing cost of mould, adopt a cover injection mold to come two kinds of plastic cement products of moulding, its structure as shown in Figure 1, a punch has two punch cores 5,6, two punch cores 5,6, two concave die cavities 1,2 cooperate respectively installation to form two die cavities 7,8, two die cavities 7,8 are connected respectively die cavity entrance 9 separately, 10, two die cavity entrance 9,10 runners 3 that connect in the sprue bush by regulating mold insert 11, an end of regulating mold insert 11 is hexagon in the top, the cross section runner 15 of bottom circle, runner 15 bottoms in cross section are set in runner 4, the other end of regulating mold insert 11 is communicated with a die cavity entrance, regulating mold insert 11 can be around circular-rotation, the outer cover of runner 3 is equipped with rotatable mold insert 12, regulating mold insert 11 is installed in the notch 13 on the rotatable mold insert 12, spring ripple pearl 14 is mounted on the bottom face of rotatable mold insert 12, by removing sprue bush, with hexagon in the top of inner hexagon spanner adjustment adjusting mold insert 11, be communicated with a die cavity entrance so that regulate the other end of mold insert 11, finish like this injection moulding to a kind of product in two kinds of plastic cement products.But there is a defective in this structure, relies on spring ripple pearl to guarantee that the reliability of adjusting is sometimes also unreliable.
Summary of the invention
For the problems referred to above, the invention provides the transferring structure of two kinds of plastic cement products of moulding in the cover injection mold, can solve the problem that prior art exists, further guarantee to transform the reliability of adjusting.
Its technical scheme is such, it comprises convex mould base, die, punch core, described die, punch core surround die cavity, described die cavity is independent separately, independently its entrance of described die cavity is communicated with runner by regulating mold insert separately, the bottom of described adjusting mold insert is circular cross section runner, described adjusting mold insert is installed in the spinning mold insert, it is characterized in that: the bottom end face of described rotation mold insert is made as blossom type, top at described convex mould base, bottom corresponding to described rotation mold insert is provided with the plum blossom groove, and the bottom of described rotation mold insert is installed in described plum blossom groove.
In the said structure of the present invention, adopt the rotation mold insert with the blossom type bottom to cooperate with the plum blossom groove on the top of convex mould base, saved existing spring ripple pearl, namely convenient, fast, guaranteed again to transform the reliability of adjusting.

The specific embodiment
See Fig. 2, Fig. 3, Fig. 4, Fig. 5, the present invention includes a convex mould base 1, two punch cores 2,3 are arranged on the convex mould base 1, two punch cores 2,3 and two concave die cavities 4,5 cooperate respectively to install and form two die cavities 6,7, two die cavities 6, the 7 die cavity entrances 8,9 that are connected respectively separately, two die cavity entrance 8,9 runners 11 that connect in the sprue bush by regulating mold insert 10, an end of regulating mold insert 10 is communicated with runner 11, the other end of regulating mold insert 10 is communicated with a die cavity entrance, and regulating mold insert 10 can be around circular-rotation.The outer cover of runner 11 is equipped with the mold insert 12 of rotation, there is notch 13 mold insert 12 inside of rotation, regulating mold insert 10 is installed in the notch 13, the bottom end face of rotation mold insert 12 is made as blossom type, top at convex mould base 1, bottom corresponding to rotation mold insert 12 is provided with plum blossom groove 14, the bottom of rotation mold insert 12 is installed in plum blossom groove 14, an end of regulating mold insert 10 is the cross section runner 16 of hexagon in the top, bottom circle, runner 16 bottoms in cross section are set in runner 15, and runner 16 tops in cross section are communicated with the runner 3 in the sprue bush.
During work, remove sprue bush, utilize inner hexagon spanner deeply to adjust hexagon in the top of regulating mold insert 10, be communicated with a die cavity entrance so that regulate the other end of mold insert 10, so just can be to the injection moulding of a kind of product in two kinds of plastic cement products, be in course of adjustment, cooperate with the plum blossom groove 14 on the top of convex mould base 1 with the rotation mold insert 12 bottom the blossom type, guarantee the reliability of its adjustment.
