Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.

A kind of plastic mould referring to FIG. 1 and FIG. 2, including cover half 100, dynamic model 200, shift piston 300, shift piston 300 Mover 310 and dynamic model 200 be sequentially connected, cover half 100 is provided with model groove, and cover half 100 includes pedestal 140, model protrusion block 120 and two movable cushion blocks 110, protrusion block and two movable cushion blocks 110 be all set on pedestal 140, movable cushion block 110 be side Shape, movable cushion block 110 are respectively arranged at the two sides of protrusion block, are connected on pedestal 140 by hinge 130.

By cover half 100, dynamic model 200, shift piston 300, one kind is formed by adopting the above technical scheme referring to Fig. 4 and Fig. 5 Two pieces of rectangular protrusion block movements are fixed on pedestal 140 by plastic mould by hinge 130.Making the first plastic sheet 400 When, a cavity is formed by the protrusion block on model groove and pedestal 140, is molded to form the first plastic sheet 400；? When making the second plastic sheet 500 connecting with the first plastic sheet 400, two pieces of movable cushion blocks 110 are gone to the two sides of protrusion block, with A cavity is formed, then the second plastic sheet 500 is formed by injection molding.By the way that two layers of modeling can be realized with movable two pieces of cushion blocks Expect the injection molding of block, simple and practical, effect is good.

Specifically: the injecting hole 210 of plastic mould is arranged on the model groove of cover half 100.The gas vent of plastic mould 220 are arranged on the model groove of cover half 100.Injecting hole 210 is equipped with filter screen.

Specifically: the quantity of the gas vent 220 of plastic mould is multiple.Gas vent 220 is equipped with check valve.

Referring in Fig. 3 technical solutions of the utility model: hinge 130 includes central axis 131, and rotation is connected to central axis Two metal blades 132 on 131, a metal blade 132 are fixed on the side of cover half 100, and another metal blade 132 is fixed In rectangular movable cushion block 110.

In the utility model embodiment, by the hinge 130 being made of central axis 131 and two metal blades 132, realize The activity of two pieces of movable cushion blocks 110, in the case where state 3, movable cushion block 110 produces, and shift piston 300 pushes dynamic model 200 form cavity, inject the plastics of hot melt by injecting hole 210, form the first plastic sheet 400；It is complete to the first plastic sheet 400 Cheng Hou unclamps shift piston 300, rotates two pieces of movable cushion blocks 110, forms state 2；Hereafter shift piston 300 pushes dynamic model again 200, the plastics of hot melt are injected, the second plastic sheet 500 is formed, form state four.The technical program is simple and practical.

The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
