Abstract
The utility model discloses a changeable injection mold in main flow channel hole footpath, including movable mould and cover half, the movable mould includes the movable mould board, installs mold core and ejecting mechanism on the movable mould board, the cavity that constitutes after movable mould board, cover half and the mold core closure is the die cavity, be provided with on the cover half with the communicating main flow channel hole of die cavity, closely install main flow pipe in the main flow channel hole, main flow pipe is a microscler cavity pipe fitting, main flow pipe's one end is the export for import, the other end. The utility model provides a changeable injection mold in main flow channel hole footpath, difference the moulding plastics of the material that requires of moulding plastics is convenient for to carry on by change owner flow pipe more as required on same mould, and simple structure, durable is fit for being applied to in the shooting technique.
Description
Technical field
The utility model relates to the variable injection mold in a kind of sprue aperture, belongs to injection molding technology field.
Background technology
A kind of processing method used when injection mold (Injectionmold) is some complex-shaped parts of batch production, is mainly used in industrial circle.Injection mold process is that the material melted that is heated is injected die cavity by high pressure, after cooling curing, obtains formed products.Mould is primarily of compositions such as running gate system, forming part and constitutional details.Wherein running gate system running gate system is also known as flow passage system, it is one group of feeding-passage of plastic melt being guided into die cavity by nozzle of injector, usually by sprue, runner, the compositions such as cast gate, sprue connects the one section passage of injection machine nozzle to runner or die cavity in mould, the porch of sprue connects with injection molding machine nozzle, when sprue inlet diameter should slightly larger than nozzle diameter to avoid flash, and intercepting of preventing both from occurring because being connected inaccurate, in addition, the cross-sectional sizes of sprue has a significant impact the flow velocity of fluid in injection moulding process, and rate of flow of fluid directly determines Forming Quality and the production efficiency of plastic products, therefore when using same mould to produce the goods of different materials, because injection raw material changes, the bore of injection molding machine nozzle and all changing to the requirement of flow velocity, if now the import size of sprue is constant, sectional area is constant, then easily there is flash, intercept, sticking to moulds etc. are abnormal.
Utility model content
Technical problem to be solved in the utility model is to provide the variable injection mold in a kind of sprue aperture, can prevent from not mating because of sprue and nozzle or sprue sectional area does not reach and to require and that injection moulding process occurs is abnormal.
For solving above technical problem, the technical solution adopted in the utility model is: the injection mold that a kind of sprue aperture is variable, comprise dynamic model and cover half, described dynamic model comprises moving platen, be installed on the core rod on moving platen and ejecting mechanism, the cavity formed after described moving platen, cover half and core rod close is die cavity, described cover half is provided with the sprue hole communicated with die cavity, in described sprue hole, close installation has main flow deferent, described main flow deferent is an elongated hollow pipe fitting, one end of described main flow deferent is import, and the other end is outlet.
The inner surface in described sprue hole and the outer surface of described main flow deferent are provided with the screw thread of mutually occlusion, achieve the compact siro spinning technology of sprue hole and main flow deferent, and when preventing injection moulding, fluid enters seam or main flow deferent is deviate from.
The sectional area of described main flow deferent is increased to Way out gradually by described import, so that the demoulding of runner excrescence.
Described outlet is connected with cast gate, and the sectional area of described cast gate is less than described discharge area, achieves and controls stream speed, and is convenient to goods and is separated with flow passage system.
Described outlet connects with runner, injection moulding while being convenient to carry out multiple die cavity.
The thimble that described ejecting mechanism comprises top board and is connected with top board.
The setting that the utility model adopts sprue hole and main flow deferent to match, can according to the main flow deferent needing the import of replacing different pore size of Shooting Technique, achieve the cooperation from the nozzle of different bore, and can need according to injection moulding the main flow deferent selecting different cross-sectional, to make fluid reach most suitable flow velocity, prevent flash in injection moulding process, intercept, the generation of the abnormal problem such as sticking to mould.
Therefore, the injection mold that a kind of sprue aperture provided by the utility model is variable, can change main flow deferent as required, be convenient to the injection moulding of the material carrying out different injection moulding requirement on same mould, structure is simple, durable, is applicable to being applied in Shooting Technique.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The injection mold that a kind of sprue aperture is as shown in Figure 1 variable, comprise dynamic model and cover half 1, described dynamic model comprises moving platen 2, be installed on the core rod 3 on moving platen and ejecting mechanism, the cavity formed after described moving platen 2, cover half 1 and core rod 3 is closed is die cavity, described cover half 1 is provided with the sprue hole 4 communicated with die cavity, in described sprue hole 4, close installation has main flow deferent 5, described main flow deferent 5 is an elongated hollow pipe fitting, one end of described main flow deferent 5 is import, and the other end is outlet.
The inner surface in described sprue hole 4 and the outer surface of described main flow deferent 5 are provided with the screw thread of mutually occlusion, achieve the compact siro spinning technology of sprue hole 4 and main flow deferent 5, and when preventing injection moulding, fluid enters seam or main flow deferent 5 is deviate from.
The sectional area of described main flow deferent 5 is increased to Way out gradually by described import, so that the demoulding of runner excrescence.
Described outlet connects with runner, injection moulding while being convenient to carry out multiple die cavity.
The thimble 7 that described ejecting mechanism comprises top board 6 and is connected with top board.
The setting that the utility model adopts sprue hole 4 and main flow deferent 5 to match, can according to the main flow deferent 5 needing the import of replacing different pore size of Shooting Technique, achieve the cooperation from the nozzle of different bore, and can need according to injection moulding the main flow deferent 5 selecting different cross-sectional, to make fluid reach most suitable flow velocity, prevent flash in injection moulding process, intercept, the generation of the abnormal problem such as sticking to mould.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
