Description
Technical field
The utility model relates generally to the technical field of mold design, the liftout attachment of specifically a kind of mold.
Background technique
The liftout attachment of traditional moulds generally uses thimble, ejector sleeve, push plate etc., can be applicable in most products and mold knot
Structure.But for more than internal structure and for product that space is small, product ejection is easily-deformable, and die cavity number is more and push plate space is inadequate
In the case where, cause product stripping difficult.107116764 A of Chinese patent literature CN discloses a kind of injection molding in 2017.9.1
The pneumatic jack core bar device of mold pneumatic jack assisted demoulding, including pneumatic jack core bar, sealing ring, type core, dynamic model support plate, pneumatic jack core bar are circle
The rod-shaped steel components of cylindricality, the groove that the top cylinder of pneumatic jack core bar is equipped with annular are known as ring air drain, the lower end of pneumatic jack core bar
The flange that cylinder is equipped with discount vibram outlet shape is known as bar foot, and the part that gas item core bar is located above the ring air drain is known as head, pneumatic jack core
The part that bar is located at below the ring air drain between the bar foot is known as the body of rod, be equipped at the cylinder of the body of rod up and down direction, with
The plane that the discount vibram outlet face of bar foot communicates is known as air guide face, and the diameter of head is less than 0.1~0.2 millimeter of diameter of the body of rod；Sealing ring
For the annular rubber texture part of circular in cross-section.When the structure demoulds, first compressed air is through air flue, air guide seam, ring air drain
Air cleft enters between type core and deep chamber product out, forms positive pressure air cushion layer, positive pressure air cushion layer between type core and deep chamber product
Deep chamber product and type core is forced to generate loosening, later, under the booster action of positive pressure air cushion layer, the upward pushing tow of the mandril of dynamic model is deep
Chamber product smoothly demoulds.Therefore, it is further improved.
Utility model content
The purpose of the utility model is to provide a kind of simple and reasonable, cost of manufacture is lower, is convenient for product stripping, has
It imitates and simplifies die products liftout attachment, to simplify the liftout attachment of the mold of mould structure, to overcome deficiency in the prior art
Place.
By a kind of liftout attachment of mold of this purpose design, including the first template and the second template, the second template-setup
There is ejection assembly, ejection assembly is located at below die products, and ejection assembly includes guiding trestle and mandril, and mandril is inserted in guiding
In bracket, top stem casing is equipped with reset spring, and mandril runs through the second template, and mandril and guiding trestle bottom end are located at the first template
Interior, the main body of mandril and guiding trestle is located in the second template；First template side correspond to mandril be provided with it is interconnected
Gas hole, gas enters in gas hole in mold die sinking, and gas in gas hole drives mandril to move above guiding trestle,
Mandril upward pressed home spring, mandril in guiding trestle move up in the first template, the second template respectively, mandril
And then ejection die product.When die sinking, gas constantly enters in gas hole, and mandril is under the influence of gas respectively in the first mould
It is moved up in plate, the second template, mandril upward pressed home spring, mandril in guiding trestle open the second template in turn
Die products, to take out die products；When molding, gas stops entering in gas hole, and mandril is resetted by reset spring,
The mandril spring that is reset bounces back into the first template, in the second template.Realize that product is easy demoulding, it is not easy to other products be caused to become
Shape drags the problems such as colored.When mold is provided with multiple die products, in the case where multiple die products, equivalent effect is played,
It is small that this structure occupies die space, has the characteristics that at low cost.
Second template corresponds to guiding trestle and is provided with mounting portion, and the corresponding second template side setting of guiding trestle is useful
In the second pin for preventing rotation, the second pin is located in mounting portion.
Mandril clearance position is provided in the guiding trestle, mandril clearance position one end is provided with stepped hole, and mandril runs through platform
Rank hole is simultaneously inserted into guiding trestle, has gap between mandril and mandril clearance position, reset is arranged between mandril and stepped hole
Spring, corresponding second template-setup in mandril side has the first pin for preventing rotation, to prevent mandril from moving up
When generate rotation, avoid mandril driven mold product rotate.First pin is located in guiding trestle.
Described mandril one end is provided with plunger tip, and guiding trestle corresponds to plunger tip and is provided with plunger tip hole, and plunger tip limits in plunger tip hole
It is interior；When die sinking, mandril drives plunger tip to movement above plunger tip hole, and plunger tip opens die products.
The mandril is provided with spacing block set, and the internal diameter of the outer diameter > stepped hole of spacing block set is being opened with limiting mandril
When the freedom degree that moves up, reset spring is set on the outside of mandril, and reset spring and spacing block set mutually limit contact, reset
Spring is set on the outside of mandril by spacing block set, stepped hole limit.When die sinking, gas enters in gas hole, and mandril drives limit
Position convex block upward pressed home spring in guiding trestle, when spacing block set touches on the outside of stepped hole, mandril cannot continue
It moves up.
The spacing block set and mandril are set as an entirety；Alternatively, spacing block set is connected with each other by screw and mandril.
When spacing block set and mandril are set as an entirety, and plunger tip and mandril are then split type setting, are first set in reset spring
On mandril, then the first pin is installed, the mandril with reset spring, the first pin is sequentially inserted into stepped hole, pilot hole, finally
Plunger tip and mandril are connected with each other by screw.When plunger tip and mandril are set as an entirety, the first pin is first installed, will be had
The mandril of pin is sequentially inserted into pilot hole, stepped hole, then reset spring is arranged in stepped hole, and last spacing block set and mandril are logical
Cross screw interconnection.
First template corresponds to guiding trestle and is provided with cavity, and in cavity, the first template is corresponding for guiding trestle bottom end
Mandril setting is fluted, and gas hole, cavity are interconnected with groove respectively, and ejector rod bottom end limits in groove；Cavity and groove
It is coaxially disposed each other.When die sinking, gas is entered in groove by gas hole, and when gas is full of entire groove, mandril is made upward
It is mobile, and the freedom degree that spacing block set limitation mandril moves up, mandril drive plunger tip ejection die product；When molding, mandril
The spring that is reset bounces back into groove.
The guiding trestle is fixed on the second template by nut, with fixed guide bracket, prevents guiding trestle to moving up
It is dynamic.
In die sinking, gas enters in gas hole and then drives the mandril of ejection assembly to moving up the mold of the utility model
It is dynamic, so that the ejecting product in the template of mold simplifies mould structure convenient for taking out die products.Realize that product is easy demoulding,
Do not allow to easily cause other deformation of products, drag the problems such as colored.When mold is provided with multiple die products, in multiple die products
In the case of, equivalent effect can be played, it is small that this structure occupies die space, has the characteristics that at low cost.
