Description
Technical field
The invention belongs to technical field of mold, is to be related to a kind of sliding block machine for bicolor injection mould more specifically
Structure.
Background technology
During mould design and manufacture, bicolor injection mould to some specific products for being for example molded into
Needed during type sliding block the first color product injection after the completion of die sinking action in remain stationary as, that is, mold when the first color when sliding block not
Product can be left, and sliding block must slide off product in the die sinking action after the completion of the injection of the second color product, and it is existing
Slide block mechanism can not meet the use demand of bicolor injection mould.
The content of the invention
It is an object of the invention to provide a kind of slide block mechanism for bicolor injection mould, it is intended to solves existing double-colored note
Mould can not meet that sliding block can not leave product during the first color during die sinking and sliding block must be molded in the second color product and complete
The problem of product being left in die sinking action afterwards.
To achieve the above object, the technical solution adopted by the present invention is：A kind of sliding block for bicolor injection mould is provided
Mechanism, including slider body, the Angle Pin for driving slider body motion, be arranged on the slider body and be used for
Accommodate the holding tank of the Angle Pin, be arranged in the slider body and be slidably connected at least with the take-up housing body
One bullet block, on the slider body and for the sliding eye that is slidably connected with the bullet block and it is arranged on the bullet block
With the elastic component between the slider body, in a free state, the inner end of the bullet block protrudes from the interior of the holding tank
Side, is provided with to be used to extrude on the bullet block inner end and drives the bullet block to slide towards the holding tank towards the one side of entrance
The first dynamic driving inclined-plane, the guiding sky for accommodating and being oriented to the Angle Pin is formed between the bullet block and the holding tank
Between.
Further, the end of the Angle Pin is provided with the second driving inclined-plane.
Further, the side of the sliding eye is provided with limit card slot, and the bullet block, which is provided with, to be used for and the limiting card
The chuck of the inner face clamping positioning of groove.
Further, the outside of the slider body is provided with the cover plate for being used for covering the sliding eye, the elastic component
One end leans with the bullet block, and the other end of the elastic component leans with the cover plate.
Further, the elastic component is spring.
Further, the cover plate is provided with the fixed structure for being used for fixing the spring.
Further, the fixed structure is the alignment pin with the spring grafting.
Further, the fixed structure is the locating slot for accommodating the spring.
Further, the bullet block has two, and plane of symmetry specular of two bullet blocks along the Angle Pin is set
Put.
Further, if the Angle Pin is provided with dry sump.
It is provided by the present invention for the beneficial effect of the slide block mechanism of bicolor injection mould：Compared with prior art,
The present invention is used for the slide block mechanism of bicolor injection mould, sets bullet block by being slided on slider body, the end of bullet block protrudes
When the medial surface of the holding tank allows part corresponding to the first color product to be molded Angle Pin do not enter bullet block and holding tank it
Between in the guide space that forms, Angle Pin of the mould without driving sliding block, when the first color formed product rear mold is opened because
The Angle Pin of slider body is not driven, slider body does not slide during die sinking；First color part mould is together with slider body and
During the mould matched moulds of two this part of color product, Angle Pin pushes down the first driving inclined-plane of bullet block outer surface, due to the effect of pressure
Elastic component is compressed, and bullet block is pushed into sliding eye, and Angle Pin is pinned with the inner surface of bullet block and tiltedly led by the resilience of rear bullet block
Post；After second color formed product, mould open, now Angle Pin by promote bullet block inner surface (this face there is no inclined-plane so
Bullet block can not be open) drive slider body to slide in and out, mould completes Angle Pin after opening and leaves slider body 1 completely
Guide space.The slide block mechanism for bicolor injection mould of the present invention, the part mould corresponding to the first color product do not have
The Angle Pin of slider body is driven, slider body motion is triggered during so as to avoid die sinking, while also allows the second color product institute right
The part mould answered has the Angle Pin of driving slider body and can be in the case where slider body holding position is motionless smoothly
Into the guide space of slider body, reach the purpose that slider body motion is triggered during die sinking, solve existing double-shot moulding
Mould mold when the first color when slider body can not leave product and also slider body the second color product injection after the completion of opening
The problem of leaving product in mould action, and simple in construction, easy to use, cost is low, beneficial to improving production efficiency.
