Further, the top of the upper die holder is equipped with the glue-feeder cooperated with injection molding machine nozzle, the glue-feeder and institute State runner connection.

Further, the runner mold insert and the part for pushing away mould cooperation are cone, bus lower end and horizontal plane Angle be greater than 75 degree and less than 90 degree.

Further, the angle is 82 degree.

Further, the buffer unit uses spring.

Compared with prior art, the utility model has the beneficial effects that: the utility model include upper die holder, push away mould and under Die holder, after the completion of bottle lid of cosmetics injection molding, lower die holder is moved downward, and lower die holder is separated with mould is pushed away, molding bottle lid of cosmetics It can stay on runner mold insert, with moving downward for lower die holder, pushing block press to buffer unit, and drive pushes away mould and moves downward, Mould and upper die holder will be pushed away to separate, mould is pushed away in this way and just bottle lid of cosmetics is ejected from runner mold insert, because the buffering of buffer unit is made With bottle lid of cosmetics eliminates the trace effect of cast gate as far as possible when runner mold insert may make to demould, and improves product quality, and production is qualified Rate improves, so that the product appearance produced is beautiful；After bottle lid of cosmetics is fallen down, mould is pushed away under the action of elasticity reset device It resets, in order to produce again, improves production efficiency.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to Fig. 1, a kind of bottle lid of cosmetics injection mould provided by the utility model, including upper die holder 1, push away mould 2 and under Die holder 3 pushes away mould 2 and is movably arranged between upper die holder 1 and lower die holder 3, and lower die holder 3 is movably arranged on the lower section for pushing away mould 2；Upper die holder 1 bottom is equipped with runner mold insert 4, which is revolving body, and one end of which is fixed on upper die holder 1, one end passes through and pushes away mould 2, It is inserted into lower die holder 3；The top of lower die holder 3 is equipped with and the matched inner cavity of runner mold insert 4, the inner wall and 4 outer wall of runner mold insert of inner cavity Between have preset gap；It the inner wall of inner cavity, the outer wall of runner mold insert 4 and pushes away the bottom surface of mould 2 and surrounds bottle lid of cosmetics Forming recess 5, shape are in Qian font；The center of runner mold insert 4 offers perforative runner 6 from top to bottom, the lower end of runner 6 It is connected to forming chamber 5, cast gate 7 is equipped at the center of the inner wall bottom of forming chamber 5, forming chamber 5 passes through cast gate 7 and runner 6 connections；The two sides of forming recess 5 are relatively set with thimble 8, and one end of thimble 8 is fixed on lower die holder 3, and the other end, which is provided with, to be pushed away Block 81 and extending into pushes away in the guide sleeve 21 set in mould 2, and vertical activity space 22 is equipped between pushing block 81 and the bottom surface of guide sleeve 21, The lower part of activity space 22 is provided with buffer unit 23；The two sides on 4 top of runner mold insert are provided with elasticity reset device 9, elasticity One end of resetting apparatus 9 is fixed on upper die holder 1, and the other end, which is extend into, to be pushed away in mould 2 and push away 2 elastic connection of mould with this.

Wherein, the top of the upper die holder 1 is equipped with the glue-feeder 11 cooperated with injection molding machine nozzle, glue-feeder 11 and runner 6 Connection.

When work: hot glue is injected in forming recess 5 by glue-feeder 11, runner 6, after the completion of bottle lid of cosmetics injection molding, Machine drives lower die holder 3 to move downward, so that lower die holder 3 be separated with mould 2 is pushed away, molding bottle lid of cosmetics can stay in runner edge On part 4, with moving downward for lower die holder 3, buffer unit 23 is arrived in the press of pushing block 81, and drive pushes away mould 2 and moves downward, and will push away mould 2 separate with upper die holder 1, push away mould 2 in this way and just bottle lid of cosmetics is ejected from runner mold insert 4, because the buffering of buffer unit 23 is made With bottle lid of cosmetics eliminates the trace effect of cast gate 7 as far as possible when runner mold insert 4 may make to demould, and improves product quality, and production is closed Lattice rate improves, so that the product appearance produced is beautiful, in the present embodiment, the buffer unit 23 uses spring, cost compared with It is low；It after bottle lid of cosmetics is fallen down, pushes away mould 2 and is resetted under the action of elasticity reset device 9, in order to produce again, improve life Produce efficiency.

In the present embodiment, the runner mold insert 4 is cone, bus lower end and horizontal plane with the part for pushing away the cooperation of mould 2 Angle be greater than 75 degree and less than 90 degree, preferably 82 degree.82 degree of cone is more convenient for demoulding.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
