Abstract
The utility model provides one kind without cast gate waste material injection mold, the program by injection mould, be fed and the single unit system that shoots material in set up plug-hole part, make it act with injection by programme-control to link, injection molding material at the end of pressing from being once molded in running channel, " cast gate " place is set no longer to have clout, now upper and lower mould separates, and corollary apparatus linkage pushes away injection-molded item（Or draw）From realizing that injection raw and auxiliary material without cast gate waste material, so as to ensure the bright and clean of injection-molded item surface and no longer manually be rejected, while has been saved in injection-molded item surface.
Description
Technical field
The utility model relates to mould, and especially one kind is without cast gate waste material injection mold.
Background technology
During carrying out rubber, plastic products are manufactured, because the design of mold injection material feeder channel is unreasonable etc.
Reason, cause passage portion clout（Main finger and injection-molded item connected component, are referred to as " cast gate waste material "）Remain on injection-molded item,
Need manually to process it again to reject the portion of residual material, because now injection-molded item has freezed off shaping, this measure will cause to note
The deficiencies of it is not clean to mould product surface, and cost of labor input will be increased, while increase raw and auxiliary material is consumed.
Compared with static discontinuous injecting condition, its solution is no longer desirable for this condition.To realize automatically continuously note
Modeling, its realization means are usually that mould on injection mold and the lockings such as feed, material injection device link together, and once injection terminates
And injection-molded item is when tentatively freezing off in place, above carries together with mould and material injection device etc. on injection mold and separated with lower mould, synchronously matched somebody with somebody
Covering device automatically pushes away injection-molded item（Or draw）From injection mold.Because mould is connected to material injection device etc. all the time on injection mold
Together, therefore the injection molding material in its " running channel " is in molten condition all the time, in the upper and lower mould time of releasing, running channel injection molding material closer to
Injection-molded item more first freezes off, and according to injection molding material in running channel when receiving identical pulling force, most weakness is broken principle at first, from pouring
It is upward along running channel at mouthful, when injection molding material can not be supported to resistant to separation generation pulling force in running channel, then will be broken first at this, then
The heels that injection-molded item will be taken out of in a part of running channel, i.e. " cast gate waste material " are invested on injection-molded item, need to be put into again artificial
It is rejected.Injection-molded item has freezed off shaping during due to artificial disposal " cast gate waste material ", and this measure will cause injection-molded item table
Face is not clean and will increase cost of labor input.The deficiencies of raw and auxiliary material consumption will be increased simultaneously.
Utility model content
The utility model mainly for dynamic auto continuous injecting condition, by injection mould, be fed and the entirety that shoots material
Plug-hole part is set up in device, it is acted with injection by programme-control and links, at the end of pressing from being once molded in running channel
Injection molding material, " cast gate " place is set no longer to have clout, now upper and lower mould separates, and corollary apparatus linkage pushes away injection-molded item（Or draw）
From realizing injection-molded item surface without cast gate waste material, so as to ensure the bright and clean of injection-molded item surface and no longer manually be rejected, together
Shi Jieyue injection raw and auxiliary materials.
This programme is achieved by the following technical measures：
One kind includes upper bolster and die block without cast gate waste material injection mold；Be provided with die block feeder channel and
Injection hole；Injection hole connects with the model cavity on upper bolster；It is with being provided with plug-hole portion at injection hole surface in feeder channel
Part；Plug-hole part is connected by drive device with cylinder；Plug-hole part can move up and down in the driving of cylinder.
As the preferred of this programme：Sealing shroud is provided between plug-hole part and the opening portion of feeder channel.
As the preferred of this programme：Drive device includes lever and support base；The both ends of lever respectively with plug-hole part
Top and cylinder movable part riveting；Support base is arranged on its intermediate part and riveted with its intermediate part.
As the preferred of this programme：Fixed between model cavity and upper bolster by screw.
As the preferred of this programme：The bottom of plug-hole part and the shape of injection hole are coincide.
As the preferred of this programme：The movable part of cylinder is set relative to plug-hole component level, and can be in vertical side
Motion upwards.
As the preferred of this programme：Plug-hole part is cylindrical rods and lower shape coincide with injection hole.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due in this scenario for dynamic auto
Continuous injecting condition, by injection mould, be fed and the single unit system that shoots material in set up plug-hole part, it is made by programme-control
Act and link with injection, using the flow behavior for melting injection molding material, the injection molding material at the end of pressing from being once molded in running channel, make
No longer there is clout at " cast gate " place, and now upper and lower mould separates, and corollary apparatus linkage pushes away injection-molded item（Or draw）From realization injection
Product surface so as to ensure the bright and clean of injection-molded item surface and no longer manually be rejected, while has saved note without cast gate waste material
Mould raw and auxiliary material.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1 is feeder channel, and 2 be sealing shroud, and 3 be plug-hole part, and 4 be lever, and 5 be support base, and 6 be cylinder, and 7 are
The movable part of cylinder, 8 be model cavity, and 9 be upper bolster, and 10 be injection hole.
Embodiment
For the technical characterstic for illustrating this programme can be understood, below by an embodiment, and its accompanying drawing is combined, it is right
This programme is illustrated.
By accompanying drawing as can be seen that this programme includes upper bolster and die block；Be provided with die block feeder channel and
Injection hole；Injection hole connects with the model cavity on upper bolster；It is with being provided with plug-hole portion at injection hole surface in feeder channel
