Description

The plastic mould of inserts location moulding

Technical field

The utility model relates to plastic mould, specifically a kind of plastic mould of inserts location moulding.

Background technology

Inserts is put into mold cavity,,, inserts and the plastic cement products that molds in conjunction with curing, are formed integration product with the mode of no external fixed component by the bonding force of melt plastic cement, the product that utilizes this kind mode to mold, bonding firm, appearance looks elegant.But in producing, manually in die cavity, place inserts, the position deviation can occur unavoidably, mould is in the matched moulds process, the phenomenon of loose or dislocation also can appear in inserts, directly have influence on the quality of product, the inserts off normal also can cause mould to weigh wounded, thus inserts how in mold cavity accurately the location be a difficult problem of industry.

The utility model content

Because above-mentioned problem, inserts can not accurate in locating in mold cavity, causes the bad of product quality.The purpose of this utility model is to overcome the deficiencies in the prior art and defective, and a kind of plastic mould of inserts location moulding is provided.

The utility model provides a kind of plastic mould of inserts location moulding, comprise master mold and male model, this master mold is overlapped successively by upper mounted plate, caster, mother module core and forms, and this male model is by male model benevolence, male model plate, upper ejector plate, liftout plate, the adjacent successively setting of bottom plate down.Master mold is gone into son, and its end connects elastic component and is arranged in this caster and this mother module core, and there are an operating range in the hanging platform of this end and this mother module core; The male model board, it is located between this male model benevolence bottom and this male model benevolence has the one stroke distance, and the trip is apart from being not less than the operating range that this master mold is gone into sub-end hanging platform and this mother module core, and is installed with male model on this male model board and goes into son; Return mechanism, it has thimble and return pin, and this thimble is arranged in this mother module core and this male model benevolence, is arranged with elastic component on this return pin, and the one end is fixedly arranged on upper ejector plate, and the other end is arranged in this male model plate and this male model board.

More excellent, described master mold is gone into son and is the red metal material.

More excellent, described master mold goes into that sheathed elastic component is a spring on elastic component that sub-end connects and the return pin.

More excellent, in the described return mechanism, the diameter of this thimble is greater than the diameter of this return pin.

Compared with prior art, the utility model utilization male model is gone into son with the inserts location, and it is simple in structure, and accurate positioning has improved the yield of product greatly.

The specific embodiment

For describing technology contents of the present utility model, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..

See also Fig. 1 and Fig. 2, be respectively male model floor map of the present utility model and assembling schematic diagram.This mould comprises master mold and male model, and wherein master mold is overlapped successively by upper mounted plate 101, caster 102, mother module core 103 and forms, and this male model is by male model benevolence 104, male model plate 105, upper ejector plate 106, liftout plate 107, the adjacent successively setting of bottom plate 108 down.

Master mold is gone into sub 109 ends connection elastic component 110 and is arranged in this caster 102 and this mother module core 103, and there are an operating range 111 in the hanging platform of this end and this mother module core 103, wherein elastic component 110 is a spring, master mold is gone into son 109 and is the red metal material, the red metal hardness number is lower, in matched moulds and process that inserts 112 contacts, can avoid inserts 112 to be gone into son 109 and weigh wounded by this master mold.

Male model board 113 is located at this male model benevolence 104 bottoms, and and has one stroke between this male model benevolence 104 apart from 114, the trip distance 114 is not less than the operating range 111 that this master mold is gone into sub 109 end hanging platforms and this mother module core 103, and be installed with male model on this male model board 113 and go into son 115, this male model is gone into son 115 ends with hanging platform and is fixedly arranged on male model board 113, and the other end is arranged in male model benevolence 104.

Return mechanism has thimble 116 and return pin 117, these thimble 116 1 ends are located at this mother module core 103, the other end is when matched moulds, be arranged in this male model benevolence 104, be arranged with elastic component 118 on this return pin 117 and be located at this mould male model side, the one end is fixedly arranged on upper ejector plate 106, and the other end is arranged in this male model plate 105 and this male model board 113, wherein the diameter of this thimble 116 is greater than the diameter of this return pin 117, and this elastic component 118 is a spring.

When mould was in die opening state, master mold was gone into son 109 under the effect of elastic component 110, and its bottom surface protrudes from the die cavity of mother module core 103.The male model board 113 of male model benevolence 104 bottoms is close to male model benevolence 104 bottom surfaces by 118 jack-up of the elastic component on the return pin 117, is fixedly arranged on male model on this male model board 113 and goes into an end of son 115 and protrude from male model benevolence 104 end faces.

Please continue to consult Fig. 3 and Fig. 4, be respectively the matched moulds process schematic diagram one and the matched moulds process schematic diagram two of the plastic mould of the utility model inserts location moulding.Inserts 112 places male model benevolence 104 end faces of mould, and male model is gone into son 115 ends that protrude from male model benevolence 104 and is arranged in the locating hole of inserts 112, determines the position of inserts 112 in mold cavity with this.During matched moulds, the injection moulding board drives the male model lateral movement, master mold is gone into son 109 and is contacted with inserts 112, its bottom surface is pressed and is located at inserts 112 end faces, this inserts 112 is fixed in the mold cavity, simultaneously, thimble 116 1 ends in the return mechanism prop up the end face of male model board 113, male model board 113 is depressed, make the male model that protrudes from male model benevolence 104 go into son 115 and draw back, after feature die lumped together fully, inserts 112 was accurately fixing in mold cavity, avoided in the process of injection moulding, the phenomenon of off normal takes place in inserts 112.

The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
