Description
Technical field
The utility model relates to a kind of plastic forming die, more specifically to a kind of modified node method of two plate plastic moulds.
Background technology
In prior art, traditional two plate plastic moulds product in shaping production is not separated with stub bar, therefore needs with manually being separated after depanning, adds later stage work amount on the one hand, adds cost of labor; Can produce in the process removing stub bar on the other hand and remove uneven phenomenon, cause the difference in product appearance, affect product attractive in appearance, assemble and result of use, leave bad impression to client.
Summary of the invention
The purpose of this utility model can be separated the modified node method of two plate plastic moulds of stub bar and product automatically when being and providing a kind of energy demoulding for prior art weak point.
The purpose of this utility model is realized by following measures: a kind of modified node method of two plate plastic moulds, it includes solid plate, front cavity, moving platen, rear cavity, thimble, rear mold fuse, cavity between front cavity, rear cavity, rear mold fuse is product die cavity, it is characterized in that also having front mould runner mold insert, rear mold runner mold insert, mold insert spring, nylon shutter, front cavity stop screw; Wherein:
Described front mould runner mold insert is made up of base and boss, the base of front mould runner mold insert is between solid plate and front cavity and be fixed by screws on solid plate, the sprue of solid plate runner is positioned at front mould runner mold insert boss position, front mould runner mold insert is also provided with the step-like cavity being screwed into moving platen for front cavity stop screw, front cavity stop screw is screwed in solid plate, and the shaft shoulder of front cavity stop screw and the shaft shoulder of step-like cavity are separated by certain gap;
Described rear mold runner mold insert is embedded in the step-like cavity of rear cavity, and be separated by between the shaft shoulder of rear mold runner mold insert and the shaft shoulder of the step-like cavity of rear cavity certain gap, and mold insert spring is positioned at the groove of the moving platen side, back of rear mold runner mold insert;
Described solid plate, front cavity, moving platen, rear cavity are closed, nylon shutter is arranged in the hole of front cavity and rear cavity concentric, cavity between the front end face of front mould runner mold insert and the rear end face of rear mold runner mold insert is the son field of solid plate runner, the section mouth of son field is connected with product die cavity, the front mould runner mold insert side of two son field section mouths is provided with the edge of a knife, the shaft shoulder of front cavity stop screw and the shaft shoulder of the gap between the step-like cavity shaft shoulder, rear mold runner mold insert and the gap of the shaft shoulder of the step-like cavity of rear cavity and the section mouth of son field corresponding.
Compared with prior art, the modified node method of a kind of two plate plastic moulds that the utility model proposes, tool has the following advantages: automatically can be removed from product by stub bar during (1) molding, greatly reduce the workload of subsequent artefacts, improve production efficiency; (2) product with stable quality, can realize full-automatic molding and produce.
Accompanying drawing explanation
Fig. 1 is the example structure schematic diagram that the utility model proposes;
Fig. 2 is that Fig. 1 embodiment A cuts open enlarged diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention is elaborated: shown in Fig. 1 ~ Fig. 2, give an embodiment of the present utility model.In figure, a modified node method for two plate plastic moulds, it includes: solid plate 1, front cavity 3, moving platen 13, rear cavity 7, thimble 9, rear mold fuse 11, front mould runner mold insert 2, rear mold runner mold insert 8, mold insert spring 10, nylon shutter 4, front cavity stop screw 12; .Cavity between front cavity 2, rear cavity 7, rear mold fuse 11 is product die cavity 5.
Described front mould runner mold insert 2 is made up of base and boss, the base of front mould runner mold insert 2 is between solid plate 1 and front cavity 3 and be fixed by screws on solid plate 1, the sprue of solid plate 1 runner 6 is positioned at front mould runner mold insert 2 boss position, front mould runner mold insert 2 is also provided with the step-like cavity being screwed into moving platen 1 for front cavity stop screw 12, front cavity stop screw 12 is screwed in solid plate 1, the gap 31 that the shaft shoulder of front cavity stop screw 12 and the shaft shoulder of step-like cavity are separated by certain.Gap 31 in this structure is the moveable scopes of front cavity.
Described rear mold runner mold insert 8 is embedded in the step-like cavity of rear cavity 7, the gap 81 being separated by certain between the shaft shoulder of rear mold runner mold insert 8 and the shaft shoulder of the step-like cavity of rear cavity 7, mold insert spring 10 is positioned at the groove of back moving platen 1 side of rear mold runner mold insert 7.Gap 81 in this structure is scopes of rear mold runner mold insert 8 movement.
Described solid plate 1, front cavity 3, moving platen 13, rear cavity 7 closes, nylon shutter 4 is arranged in the hole of front cavity 3 and rear cavity 7 concentric, cavity between the front end face of front mould runner mold insert 2 and the rear end face of rear mold runner mold insert 8 is the son field of solid plate runner 6, the section mouth of son field is connected with product die cavity 5, front mould runner mold insert 2 side of two son field section mouths is provided with the edge of a knife, gap 31 between the shaft shoulder of front cavity stop screw 12 and the step-like cavity shaft shoulder, the shaft shoulder of rear mold runner mold insert 7 is corresponding with the section mouth of son field with the gap 81 of the rear cavity step-like cavity shaft shoulder.
The utility model is work like this: after mold injection molding, drive fixed mold core and dynamic model side's plate to move by nylon shutter during die sinking simultaneously, at the same time, dynamic model runner mold insert rises because of the elastic force of mold insert spring, the junction of the edge of a knife that front mould runner mold insert side is provided with to stub bar and product is cut until cut off, meanwhile, when front cavity is reduced to zero with the gap between the shaft shoulder of front cavity stop screw 12 and the step-like cavity shaft shoulder, moving platen continues mobile, the constraint to front cavity removed by nylon shutter, front cavity stops mobile, product is then ejected by thimble, complete whole product injection molding process.Nylon shutter is commercial products, can buy from market.
Describe embodiment of the present utility model by reference to the accompanying drawings above; the structure that embodiment provides does not form restriction of the present utility model, and in this area, those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain.
