Description
Technical field
The utility model belongs to advanced manufacture and automatic field, and in particular, to a kind of plastic mold directly pushes up quick ejection
Structure.
Background technique
It is single in the ejection system structure of existing Injection Industry, injection mold, in manufacturing with rapid changepl. never-ending changes and improvements, has only and change
Become, innovative ability is based on industry forefront.Although traditional ejection system can satisfy client to product to a certain extent
Demand, but it is detrimental to the production cost of reduction company.
Oblique top region is functor region, need to manufacture and design mold by product 3D, not allow deformation of products.Take a broad view of product knot
If structure design oblique top depanning now has back-off, it is unable to satisfy oblique top and completes ejection movement.So be changed to directly push up ejecting structure,
And this region directly pushes up needs and completes to accelerate ejection, and manipulator is facilitated to take product.
But straight roof construction has the following problems at present:
1, conventional to accelerate ejecting mechanism, occupied space.Design of part is complicated, and cost is also higher, in mold life cycle management
In it is also often desirable to renewal part；
2, the larger acceleration ejection of part is general highly difficult, acts not smooth.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide a kind of plastic molds directly to push up Quick ejection structure, solves
It is used sometimes in plastic mold and accelerates this structure of ejecting mechanism to accelerate the technical issues of ejecting plastic part.
Technical solution: the utility model provides a kind of plastic mold and directly pushes up Quick ejection structure, including cover half side, dynamic model
Mandril, lever, upper cushion block, impact block, lower cushion block, roller pin, upper ejector plate, lower liftout plate and bottom plate are directly pushed up in side, described
Cover half side is located at dynamic model upper side, and the dynamic model side is arranged on bottom plate, the straight top mandril, lever, upper cushion block, shock
Block, roller pin, upper ejector plate and lower liftout plate are arranged in dynamic model side, and the upper end of the straight top mandril is bonded with product,
The lower end of the straight top mandril and one end of lever connect, and the other end and impact block of the lever far from straight top mandril connect
