Abstract
The invention aims at providing a mold for injection molding of a terminal cover. An inner forming block and outer forming blocks are arranged to form a forming cavity for injection molding. The right side of the forming cavity is connected with an injection channel for raw material injection. After injection molding, pressing plates on the inner side walls of the injection channel are used for pressing waste of the formed terminal cover, and the pressing plates are pressed by pressing air cylinders. Then a movable mold body is started for mold opening, and the pressing air cylinders are released immediately after inductors of locating columns induct starting at this moment so that the formed terminal cover cannot be attached to the interior of the forming cavity. Then ejector rods are used for ejection. The mold is quite convenient to use, efficient, quick and suitable for production.
Description
Technical field
The present invention relates to the production field of terminal cover, particularly relate to a kind of mould of terminal cover injection moulding.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector.It thermoplastic or thermosetting plastics is utilized mould for plastics to make the main former of the plastic products of various shape.Topmost in injection machine is exactly injection mold.My company's mainly production insulation framework and terminal cover, terminal cover mainly adopts injection machine to carry out injection mo(u)lding.Because terminal cover needs to carry out blanking to it after injection mo(u)lding, all adopt the knock-pin of dynamic model to eject at present, but because sometimes terminal cover can be close in die cavity, push rod ejects can very energetically, easily eject mark at terminal cover, therefore need to solve the mark problem ejected, therefore solve the problem and just seem very necessary.
Summary of the invention
For solving the problem, the invention provides a kind of mould of terminal cover injection moulding, by arranging interior forming blocks and the injection moulding of outer forming blocks formation forming cavity, gate cast raw material is connected on the right side of forming cavity, after injection mo(u)lding, the waste part of shaping complete terminal cover is compressed by the pressing plate of gate madial wall, dynamic model starts die sinking afterwards, now the inductor of locating dowel senses to start and unclamps compression cylinder at once, shaping terminal cover so just can be made can not to be close in forming cavity, ejected by push rod more afterwards, solve produced problem in background technology.
The object of this invention is to provide a kind of mould of terminal cover injection moulding, include the dynamic model in left side and the cover half on right side, turn right in the middle of right side in described dynamic model and be protruding with interior forming blocks, be provided with forming cavity in the dynamic model outside interior forming blocks and cover half, in the dynamic model outside forming cavity and cover half, outer forming blocks is set; The centre, right side being positioned at forming cavity in described cover half is provided with gate, and gate is connected on forming cavity; In described gate, upper and lower two side, right side is provided with pressing plate, be connected with connecting rod outside pressing plate, connecting rod is connected with compression cylinder through cover half, and compression cylinder is arranged on the upper and lower both sides of cover half.
Further improvement is: in described dynamic model, left side is provided with slurcam, and be provided with push rod on the right side of slurcam, push rod right-hand member is connected to the left side of forming cavity.
Further improvement is: be connected with promotion post on the left of described slurcam, promotes post and is used for being connected with injection machine.
Further improvement is: be positioned at gate place on the right side of described cover half and be provided with installing ring for being connected with injection machine.
Further improvement is: in described dynamic model, corner, right side is provided with positioning chamber, and on the left of described cover half, corner is protruding with the locating dowel corresponding with positioning chamber, and locating dowel head is provided with inductor.
Further improvement is: described pressing plate is that magnetic sheet can be close on gate sidewall.
Beneficial effect of the present invention: the present invention is by arranging interior forming blocks and the injection moulding of outer forming blocks formation forming cavity, gate cast raw material is connected on the right side of forming cavity, after injection mo(u)lding, the waste part of shaping complete terminal cover is compressed by the pressing plate of gate madial wall, pressing plate is by the compression of compression cylinder, dynamic model starts die sinking afterwards, now the inductor of locating dowel unclamps compression cylinder after sensing startup instantaneously, shaping terminal cover just can be made can not to be close in forming cavity, ejected by push rod more afterwards, very convenient, efficiently rapidly, be applicable in production.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that dynamic model of the present invention and cover half separate.
Wherein: 1-dynamic model, 2-cover half, forming blocks in 3-, 4-forming cavity, the outer forming blocks of 5-, 6-gate, 7-pressing plate, 8-connecting rod, 9-compression cylinder, 10-slurcam, 11-push rod, 12-promotes post, 13-installing ring, 14-positioning chamber, 15-locating dowel, 16-inductor.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of mould of terminal cover injection moulding, include the dynamic model 1 in left side and the cover half 2 on right side, turn right in the middle of right side in described dynamic model 1 and be protruding with interior forming blocks 3, be provided with forming cavity 4 in dynamic model 1 outside interior forming blocks 3 and cover half 2, in the dynamic model 1 outside forming cavity 4 and cover half 2, outer forming blocks 5 is set; The centre, right side being positioned at forming cavity 4 in described cover half 2 is provided with gate 6, and gate 6 is connected on forming cavity 4; In described gate 6, upper and lower two side, right side is provided with pressing plate 7, be connected with connecting rod 8 outside pressing plate 7, connecting rod 8 is connected with compression cylinder 9 through cover half 2, and compression cylinder 9 is arranged on cover half about 2 both sides.In described dynamic model 1, left side is provided with slurcam 10, and be provided with push rod 11 on the right side of slurcam 10, push rod 11 right-hand member is connected to the left side of forming cavity 4.Being connected with on the left of described slurcam 10 and promoting post 12, promoting post 12 for being connected with injection machine.Be positioned at gate 6 place on the right side of described cover half 2 and be provided with installing ring 13 for being connected with injection machine.In described dynamic model 1, corner, right side is provided with positioning chamber 14, and on the left of described cover half 2, corner is protruding with the locating dowel 15 corresponding with positioning chamber 14, and locating dowel 15 head is provided with inductor 16.Described pressing plate 7 can be close on gate 5 sidewall for magnetic sheet.
