Abstract
The invention discloses a plastic mold dissolving wire structure. The plastic mold dissolving wire structure comprises a fixed mold and a movable mold, wherein the fixed mold is internally provided with a cavity; the movable mold is internally provided with a cavity core. The plastic mold dissolving wire structure is characterized in that the fixed mold is provided with a spurt; a main runner is arranged between the spurt and the cavity; a material slot insert capable of discharging cold plastic materials is arranged on a filler tail end between the cavity and the cavity core. Aiming to overcome defects in the prior art, the invention provides the plastic mold dissolving wire structure which is simple in structure, is convenient to process, and is low in production cost.
Description
Technical field
The present invention relates to a kind of plastic mould and weld line structure.
Background technology
Relating to plastic cement products, to have the mode adopting while welding line be to improve mould local temperature to existing plastic mould, adjust the parameter of forming machine etc., put forward quotient module tool local temperature and need increase the part of heating, the machine of temperature control etc., the wither parameter of whole forming machine, likely affects again the size appearance effect etc. of other part of product.
So existing mold plastic cement products welds line structure and awaits further perfect.
Summary of the invention
The object of the invention is, in order to overcome weak point of the prior art, provides a kind of simple in structure, easy to process, and the plastic mould that production cost is low welds line structure.
In order to achieve the above object, the present invention adopts following scheme:
A kind of plastic mould welds line structure, include fixed half and moving half, in described cover half, be provided with die cavity, in described dynamic model, be provided with core, it is characterized in that: on described cover half, be provided with sprue bushing, between described sprue bushing and die cavity, be provided with sprue, on the filling end between die cavity and core, be provided with the more hopper mold insert that cold moulding sizing material can be discharged.
A kind of plastic mould as above welds line structure, can make product and the separated thimble of hopper mold insert of healing while it is characterized in that being provided with die sinking on described dynamic model.
A kind of plastic mould as above welds line structure, it is characterized in that described cover half includes solid plate, and described die cavity is arranged in cover half pulls, and is provided with cover half panel on described solid plate.
A kind of plastic mould as above welds line structure, it is characterized in that described dynamic model includes moving platen, described core is arranged in described moving platen, on described moving platen, is connected with moving clamping plate, between described moving clamping plate and moving clamping plate, is provided with ejector retainner plate.
The large gradient sprue of a kind of new type plastic mould as above enters to water structure, it is characterized in that described ejector retainner plate includes Ejector Retainer Plate, is provided with thimble panel on described Ejector Retainer Plate.
In sum, the present invention with respect to its beneficial effect of prior art is:
The present invention is simple in structure, easy to process, and production cost is low, easy for installation.
Accompanying drawing explanation
Fig. 1 is the intent of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing explanation and the specific embodiment, the invention will be further described:
A kind of plastic mould as shown in Figure 1 welds line structure, include cover half 1 and dynamic model 2, in described cover half 1, be provided with die cavity 3, in described dynamic model 2, be provided with core 4, on described cover half 1, be provided with sprue bushing 5, between described sprue bushing 5 and die cavity 3, be provided with sprue 6, on the filling end between die cavity 3 and core 4, be provided with the more hopper mold insert 7 that cold moulding sizing material can be discharged.
The present invention can make product and the separated thimble 8 of hopper mold insert 7 of healing while being provided with die sinking on described dynamic model 2.
Cover half 1 described in the present invention includes solid plate 11, and described die cavity 3 is arranged on cover half and pulls in 11, on described solid plate 11, is provided with cover half panel 12.
Ejector retainner plate described in the present invention 23 includes Ejector Retainer Plate 231, on described Ejector Retainer Plate 231, is provided with thimble panel 232.
When producing, plastic cement first flows into die cavity from forming machine through sprue, core is after filling after a while, die cavity and mold filling are full, multiply plastic cement is joined in product end filling position, owing to flowing plastic cement through a segment distance when product end is fused, because material temperature declines to some extent, plastic cement has just produced and has welded line when molten being combined together, product filling end of the present invention increases a plastic cement that more hopper mold insert falls the end by temperature and flows to more hopper mold insert the inside, through runner, cold burden is discharged, and automatic and separation of products when product ejects, does not need 2 processing.Thereby the plastic cement like this in die cavity just there will not be quality and the production time that welds line assurance product.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
