Description
Technical field
The utility model relates to a kind of molds, and in particular to one kind is made for solving tunnel gate demoulding moment attack product
The injection mold mechanism of part is collapsed at product.
Background technique
Currently, many injection-molded items have the characteristics of flat class, small size, lightweight, caused by this based article is limited because of structure
Movable model chamber is shallow.To improve production efficiency, also use tunnel gate in current such production of articles, such cast gate can push up more
It realizes that cast gate is automatically cut off when out, but since this based article movable model chamber is shallow, if still push rod is ejected using tradition material, pours
Mouthful breaking moment material is bending deformation, when expecting recoverable force, cast gate just can attack hit the product for just taking off release chamber, cause
Product collapses part, this process is as shown in Figure 2.
Utility model content
The technical problems to be solved in the utility model is that push rod is ejected material handle using tradition material, when expecting recoverable force,
Cast gate just can attack hit the product of just de- release chamber, cause product to collapse part, provide a kind of high reliablity prevents latent pour
Mouth demoulds the injection mold mechanism for moment product being caused to collapse part.
In order to solve the above technical problems, the utility model adopts the following technical solutions: one kind prevents tunnel gate from demoulding wink
Between cause product to collapse the injection mold mechanism of part, including dynamic mould fixing plate and dynamic model piece, be equipped with push rod above dynamic mould fixing plate
Fixed plate, push plate further include middle shoulder push rod and material push rod, the material is in contact push rod one end with the upper surface of push plate,
The other end is in contact with the lower surface of material handle in dynamic model piece；The upper surface phase of described middle shoulder push rod one end and dynamic mould fixing plate
Contact, the other end are in contact with the lower surface of product in dynamic model piece；Empty avoiding is equipped between the ejector pin retaining plate and push plate
Region.
The empty avoiding region is the cylinder counterbore being arranged on ejector pin retaining plate, is equipped with and hangs in the middle part of the middle shoulder push rod
The top of cylinder counterbore is arranged in platform, hanging platform.
The material is fixed on the lower end of push rod between ejector pin retaining plate and push plate.
Shoulder push rod and material combine push rod to the utility model in use in the ejecting mechanism of mold, and in middle shoulder push rod
Setting delay empty avoiding region, reasonable Arrangement form reliable and stable delay device after step.Realization is initially switched off cast gate, ejection material
, eject product afterwards, eliminate the ill effect that tunnel gate breaking moment attack product causes product to collapse part, and cost compared with
Low, high reliablity, applicability are wide.
Detailed description of the invention
Fig. 1 is that tunnel gate causes product to collapse the process schematic of part in the prior art: wherein scheming a is knot before product ejection
Structure schematic diagram；When figure b is product ejection process, structural schematic diagram of the material deformation；Scheming c is after product ejects, and material is extensive deforming
It is multiple, hit structural schematic diagram when product.
Fig. 2 is the utility model structure diagram；
Fig. 3 is enlarged structure schematic diagram at the utility model empty avoiding region.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 to Figure 3, the utility model includes dynamic mould fixing plate 7 and dynamic model piece 10,7 top of dynamic mould fixing plate
It further include middle shoulder push rod 12 and material push rod 11, the material is 11 one end of push rod and push plate equipped with ejector pin retaining plate 5, push plate 6
6 upper surface is in contact, the other end is in contact 21 lower surface with material in dynamic model piece 10；Described middle 12 one end of shoulder push rod
It is in contact with the upper surface of dynamic mould fixing plate 7, the other end is in contact with the lower surface of product 22 in dynamic model piece 10；Described pushes away
Empty avoiding region 14 is equipped between bar fixed plate 5 and push plate 6.
The empty avoiding region 14 is the cylinder counterbore 16 being arranged on ejector pin retaining plate 5, in the middle shoulder push rod 12
Portion is equipped with hanging platform 13, and the top of cylinder counterbore 16 is arranged in hanging platform 13.
The material is fixed on the lower end of push rod 11 between ejector pin retaining plate 5 and push plate 6.
The utility model further includes cover half fixed plate 1, and solid plate 2 is equipped with below cover half fixed plate 1, is set below solid plate 2
There are moving template 3 and dynamic model piece 10, is equipped with support plate 4 below moving template 3.
After mold completes melt injection, cooling, pressure maintaining period, into die sinking ejection process.Utility model in use,
Injection molding lathe center 15 first pushes push plate 6 and ejector pin retaining plate 5 to move upwards, and is fixed between ejector pin retaining plate 5 and push plate 6
For eject material 21 material push rod 11 also and then move, first ejection material handle, at this time expect be detached from 21 with product 22；At this moment
Middle shoulder push rod 12 remains stationary: because when middle part hanging platform 13 lower bottom part of 6 upper surface of push plate not in contact with middle shoulder push rod 12, due to
There is delay empty avoiding region 14, middle shoulder push rod 12 will not move, and product 22 does not also move in dynamic model piece 10.
Secondly, when 13 lower bottom part of middle part hanging platform of shoulder push rod 12 in the contact of 6 upper surface of push plate and when continuing up, just
It will push middle shoulder push rod 12 to move upwards, and then eject the product 22 in dynamic model piece 10, this process material still exists push rod 21
Ejection material handle is moved synchronously, until material handle and product are completely fallen off, ejection process terminates.
The utility model is to realize product by the empty avoiding distance of middle shoulder push rod and expect the asynchronous of handle in entirely moving
Ejection, eliminates the influence that cast gate ejects product.Product and material are molded the thimble return of lathe, push rod is fixed after ejection
Plate 5 is resetted in the case where release link spring 8 and release link 9 act on, and drives push plate 6, material that push rod 11 and middle shoulder push rod 12 are resetted.Finally
Mold clamping, into next production cycle.
