Description

Advance glue side ejecting structure

[technical field]

The utility model relates to a kind ofly can eject ejecting structure in the mould with product in that to advance the glue side be the master mold direction.

[background technology]

In the backward flow type mould, can not when ejecting, the male model side eject with regard to using oil hydraulic cylinder etc. to assist as fruit product.The processing mode cost can be very high like this.And in double color mould, the product needed post forming, promptly the product of moulding for the first time breaks away from first master mold and stays male model, and this male model and second master mold carry out the moulding second time more then.But when first time die sinking,, then for the second time advance glue and just can't finish as the sticking male model of fruit product (non-advance glue side).Be to eject with jacking block in the past in the product side, if but product needed during with four sides slide block moulding, when promptly the male model side did not have breaking face, jacking block just can not use.

In view of this, be necessary in fact to provide a kind of ejecting structure of can be when master mold breaks away from product being stayed in the male model.

[summary of the invention]

The purpose of this utility model is to provide a kind of ejecting structure that can product be ejected in master mold side (advancing the glue side).

For reaching above-mentioned purpose, the utility model proposes a kind of glue side ejecting structure that advances, what be used for the backward flow type mould directly ejects mother module core with product, and double color mould product is ejected mother module core, stay and carry out in the male model benevolence after the moulding second time or the moulding for the second time product being ejected die, wherein, caster is arranged with a top board groove towards the one side of mother module core, be installed with, lower roof plate, and continue to extend some spring grooves around this top board groove, pressure is established some springs at the bottom of this spring groove and between the upper surface of upper plate, again, lower roof plate departs from the center and is provided with the shoulder hole that several same directions are extended, respectively in order to wear return pin and thimble, this return pin, one end of thimble passes mother module core respectively and heads on male model benevolence and product, the end face of the other end is respectively with last, the lower roof plate interface is concordant, and on, lower roof plate locks with securing member, then this return pin, thimble is fixed in, on the assembly of lower roof plate.

Compared with prior art, the utility model is provided with ejecting structure on the master mold that advances the glue side, then can when die sinking, eject product or prevent that product from gluing master mold, be applicable to that the outward appearance part can not stay under the situation of the sticking master mold of thimble vestige and double color mould to use the real the purpose of this utility model of having reached.

[description of drawings]

Fig. 1 advances glue side ejecting structure in the front view of matched moulds state for of the present utility model.

Fig. 2 advances glue side ejecting structure in the front view of die opening state for of the present utility model.

[specific embodiment]

Please refer to Fig. 1, of the present utility model advance that glue side ejecting structure is used for the backward flow type mould directly product is ejected mother module core, and double color mould product is ejected mother module core, stay and carry out in the male model benevolence after the moulding second time or the moulding for the second time product being ejected die, wherein, caster 1 is offered a top board groove towards the one side of mother module core 2, be installed with,

lower roof plate

61,62, this top board groove depth is last, lower roof plate 61, on 62 thickness reach and are somebody's turn to do,

lower roof plate

61,62 ejection strokes add and, and on the matched moulds state is somebody's turn to do down,

lower roof plate

61,62 are withstood on the top board bottom land, continue to extend some spring grooves around this top board groove, press and establish some springs 51 at the bottom of this spring groove and between the upper surface of upper plate 61.Again, lower roof plate 62 departs from the central axis position and is provided with the shoulder hole that several same directions are extended, respectively in order to wear return pin 5 and thimble 7, one end of this return pin 5, thimble 7 passes mother module core 2 respectively and heads on male model benevolence 3 and product 4, the end face of the other end is concordant with upper and lower

top board

61,62 interfaces respectively, and upper and

lower top board

61,62 is with the locking of securing members such as screw, and then this return pin 5, thimble 7 are fixed on the assembly of upper and

lower top board

61,62.

This caster 1 away from the one side group of mother module core 2 establish an adaptor, this adaptor extends a runner 8 to male and

female die

2,3 interfaces, this runner 8 comprises the first flow of bending at angle with the adaptor bearing of trend of epimere or parallel bending, and this first flow end extends central axis one segment distance and pass upper and

lower top board

61,62 straight lines and enter male and

female die

2,3 interfacial second runners at interval.

During assembling, return pin 5, thimble 7 at first penetrate the shoulder hole of lower roof plate 62, upper plate 61 covers the return pin 5 of lower roof plate 62, the opposing face that thimble 7 passes face then, and with in the locking of securing members such as screw,

lower roof plate

61,62, then this return pin 5, thimble 7 are fixed on the assembly of upper and

lower top board

61,62, at last spring 51 are placed spring groove.

During die sinking for the first time, referring to Fig. 2, move on the caster 1, spring 51 loosens, upper and lower

top board

61,62 moves to mother module core 2 directions thereupon, return pin 5 moves down, its stroke is less than the stroke of this caster 1, change disengaging male model benevolence 3 until return pin 5 gradually into by contacting male model benevolence 3, this moment, thimble 7 still withstood product 4, waited until that upper and lower

top board

61,62 runs to mother module core 2 bottoms, and thimble 7 ejects action and finishes and break away from product 4, this moment, product 4 was stayed rotation in the male model benevolence 3, conveniently carried out the moulding action second time.

During matched moulds, consult Fig. 1 and Fig. 2 in the lump, male model benevolence 3 will be pressed on return pin 5 returns, and spring 51 compressions move until withstanding the top board bottom land on the upper and

lower top board

61,62, and thimble 7 enters in the forming cavity.

The position of above return pin just is provided with in order to narrate the utility model, but is not limited only to the content of this specification, only need can not with the position of male model benevolence breaking, and can not withstand on slide block and go into son and go up and get final product.

The coefficient of elasticity of spring can not be too during big otherwise matched moulds the reaction force of return pin excessive and make roof deformation.
