Shrapnel part is compressed, and has elastic potential energy；After mold die sinking, when the straight top is ejected by the ejector retainner plate, due to elasticity
Deformation, the shrapnel part can be sprung back, so that the forming part be made to be detached from product buckle.
It further, further include mold A plate；The mold A plate is correspondingly arranged in above the mold B plate；The mold A
Intralamellar part is equipped with front cavity.
It further, further include Ejector Retainer Plate, the Ejector Retainer Plate is set to the ejector retainner plate lower part.
Further, the ejector retainner plate is bolted on the Ejector Retainer Plate.
The beneficial effects of the utility model are that the tripping mechanism is equipped with the straight top that the straight inverted draw cut moves up and down；It is described
Straight top material is flexible spring steel；The straight top successively includes fixed part, shrapnel part and forming part from top to bottom；It is described
Fixed part is embedded in the ejector retainner plate；The shrapnel part and the forming part are in the straight inverted draw cut；The forming part
Left side and top are in contact with type chamber, and left side has the groove for forming product buckle, right side and the straight inverted draw cut face contact；?
When mold clamping, the straight top is compressed in the straight inverted draw cut, and the shrapnel part is compressed, and has elastic potential energy；In mould
After tool die sinking, when the straight top is ejected by the ejector retainner plate, due to elastic deformation, the shrapnel part can be sprung back, to make described
Forming part is detached from product buckle, realizes the tripping ejection of product；The mechanism threads off compared to sliding block, designs time saving, processing letter
It is single, and simple to install is convenient, effectively improves production efficiency；And the use of inclined guide is avoided, so that injection mould is signed an undertaking
Structure tends to simple, produces the injection molding in later period more stable, and security performance improves, to client reduce maintenance cost and maintenance at
This.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in FIG. 1 to FIG. 2, which includes mold B plate 1, the rear cavity that is set to inside the mold B plate 1
2, the ejector retainner plate 3 and Ejector Retainer Plate 4 of 1 lower section of mold B plate are set to；The ejector retainner plate 3 is bolted on the top
On needle bottom plate 4；The mold B plate 1 and the rear cavity 2 have a straight inverted draw cut 5；It further include mold A plate；The mold A plate
It is correspondingly arranged in 1 top of mold B plate；The mold A intralamellar part is equipped with front cavity；Further including can be in the straight inverted draw cut 5
The straight top 6 moved up and down；6 materials of the straight top are flexible spring steel；The straight top 6 successively includes fixing from top to bottom
Portion 61, shrapnel part 62 and forming part 63；The fixed part 61 is embedded in the ejector retainner plate 3；The shrapnel part 62 and it is described at
Type portion 63 is located in the straight inverted draw cut 5；The left side and top of the forming part 63 are in contact with type chamber, and left side have formed
The groove 64 of product buckle, right side and straight 5 face contact of inverted draw cut；In mold clamping, the straight top 6 is compressed in described straight
In inverted draw cut 5, the shrapnel part 62 is compressed, and has elastic potential energy；After mold die sinking, the straight top is 6 by the ejector retainner plate 3
When ejection, due to elastic deformation, the shrapnel part 62 can be sprung back, so that the forming part 63 be made to be detached from product buckle.
The spring steel that the straight top 6 uses is used exclusively for the steel of manufacture spring and elastic element；The elasticity of steel depends on
The ability of its flexible deformation, i.e., within the scope of defined, the ability of flexible deformation makes it bear certain load, goes in load
Except not being permanently deformed later, and original state can be sprung back to because of elastic deformation.
Working principle: when being opened after formed product, the mold A plate and the front cavity are motionless, the mold B plate 1,
The rear cavity 2, the product 7, the straight top 6, the ejector retainner plate 3 and the Ejector Retainer Plate 4 move down simultaneously, wait movements
After the die sinking distance set to injection molding machine；Start carry out ejection stroke, at this time the Ejector Retainer Plate 4 push the ejector retainner plate 3 to
Upper movement, the straight top 6 are moved because bottom is embedded on the ejector retainner plate 3 with the movement of the ejector retainner plate 3,
When the straight top 6 removes the straight inverted draw cut 5, due to elastic deformation, the shrapnel part 62 can be restored to original shape, drive
63 forming part is sprung back to the right, is detached from product buckle 8, so that product 7 smoothly ejects, realizes tripping ejection.State at this time
As shown in Figure 3.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that the present utility model is not limited to the above embodiments, the above embodiments and description only describe this
The principle of utility model, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various change
And improvement, these various changes and improvements fall within the scope of the claimed invention.The utility model requires protection scope
It is defined by appending claims and equivalents.
