Description
Technical field
The utility model relates to a kind of injection forming mold with slide block structure.
Background technology
When making plastic cement products by injection forming method, tend to stay stub bar on the surface of product, removing stub bar can still can leave a trace on the surface of product, to some products strict (such as the electronic product casing moulding) concerning outward appearance, the outer surface of these products is not allow to occur vestige, therefore, require the master mold side of injection forming mold not allow to add a little, this has just brought very big difficulty to injection mo(u)lding.
Summary of the invention
The purpose of this utility model provide a kind of will advance a little be incorporated into the injection forming mold that the male model side penetrates from the master mold side.
For achieving the above object, the technical solution adopted in the utility model is: a kind of injection forming mold, the male model plate that it comprises upper mounted plate, be arranged on caster on the described upper mounted plate, be fixedly installed on mother module core on the described caster, be arranged on mother plate sliding block on the described caster movably, be oppositely arranged with described caster, be fixedly installed on male model benevolence on the described male model plate, be slidably disposed on the male model slide block on the described male model benevolence, described male model benevolence, mother module core, male model slide block, mother plate sliding block one common peripheral forming cavity; Described caster is provided with first Angle Pin, and described mother plate sliding block flexibly is enclosed within on described first Angle Pin, offers charging hole on the described mother plate sliding block, is θ perpendicular to the angle between the side wall surface of the plumb line of horizontal plane and described charging hole
1°, the axial line of described first Angle Pin and the angle between the plumb line are θ
2°, and θ
1°＞θ
2°; Described mother module core is provided with into clicks and enters son, offers on the described caster and described first hot flow path that advances to click and enter the intracavity inter-connection of son; Offer on the described male model benevolence glue groove into, with the described point into and be communicated with described hiding into and second hot flow path of die cavity of hiding that advances that the glue groove is connected; When described injection forming mold matched moulds, describedly advance to click and enter son and be inserted in the described charging hole, and described advance to click and enter son be positioned at described advance the glue groove directly over.
Also be provided with knock-pin on the described male model plate movably, described knock-pin be positioned at described advance the glue groove under.
Also be provided with knock pin on the described male model plate movably, described knock pin be positioned at described second hot flow path under.
Described bottom of advancing to click and enter son has the tapered portion that cross section diminishes gradually, and the cross section of described tapered portion is rectangle or circle.
Also be provided with stripper plate between described upper mounted plate and the caster, described upper mounted plate is provided with gate bush, and described gate bush is connected with described first hot flow path.
The utility model operation principle is: when described injection forming mold matched moulds, describedly advance to click and enter son and be inserted in the described charging hole, and described advance to click and enter son be positioned at described feed well directly over.After injection moulding finished, the male model plate separated with caster; Then, mother plate sliding block separates to both sides with the male model slide block, advances to click and enter son and breaks away from charging hole gradually; Also be provided with stripper plate between described upper mounted plate and the caster, when the male model plate with after caster separates fully, upper mounted plate and stripper plate and caster are separated from each other; Subsequently, stripper plate descends, and the stub bar that remaining plastic cement in first hot flow path forms is removed from upper mounted plate 1; Then, knock-pin stretches out, and will remain in feed well and the into interior stub bar of hiding ejects, and knock pin stretches out, and remaining stub bar and injecting products in second hot flow path are ejected.The injecting products that obtains by the utility model manufacturing all forms bright and clean outer surface at master mold side and male model slide block and mother plate sliding block one side, therefore can satisfy the harsh requirement of client to product external surfaces.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the utility model will advance a little and cause the male model side from the master mold side, at the four sides all is slide block, and the master mold face does not allow to add under a little the situation, can satisfy the injection moulding requirement of product; In addition, the utility model also avoided because of slide block movement to the burr that advance a generation, draw harmful effects such as bits, pressing mold, issuable mould fault when having reduced production in enormous quantities has improved production efficiency.Simultaneously, the utility model also has the advantage of easy processing.
