Chamber.When product bottom end forms and is buckled to, molding back-off is protruded by the bottom end of type chamber generally by pin, but in demoulding, need
Pin opposing product is moved upwards, then exits product from side again, to realize demoulding.But existing mold is de-
Mould is inconvenient, be easy to cause damage of product.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide it is a kind of convenient for bottom end pin demoulding
Mold, pin can be in the drive bottom knockouts of oblique top.
The purpose of this utility model is implemented with the following technical solutions:
A kind of mold convenient for the demoulding of bottom end pin, including cope plate, lower template, oblique top, pin and ejecting mechanism, on
Template, lower template and bottom plate are from top to bottom set gradually, and cope plate and lower template are installed on bottom plate；Cope plate can
It moves towards close to or far from lower template to mold or be opened, cope plate and lower template are used for the shape forming cavity in molding；
Lower template is equipped with jack hole, and the top of oblique top is movable to be connected in jack hole and under the action of ejecting mechanism
It moves upwards, oblique top gradually slopes inwardly from the bottom to top；Pin middle-end is articulated in the top of oblique top, and one end of pin is by oblique top
Outside stretch out and be used to be protruded by type chamber in molding and form back-off with the bottom end in product；The other end of pin is by oblique top
Inside is stretched out and is slidably matched in die sinking with the inner wall of jack hole.
Preferably, ejecting mechanism includes ejector retainner plate, and ejector retainner plate is mounted on bottom plate and can be under the drive of external force towards leaning on
Close or separate lower template moves；The bottom end of the oblique top is installed on ejector retainner plate.
Preferably, ejector retainner plate is equipped with mounting blocks, and mounting blocks are equipped with sliding slot, and the bottom end of oblique top is slidably mounted at sliding slot
It is interior.
Preferably, the mold that should be demoulded convenient for bottom end pin further include the Guiding machine for guiding ejector retainner plate to move up and down
Structure；Guiding mechanism includes guide post and pilot hole, and pilot hole is opened on ejector retainner plate；Guide post is installed on bottom plate and passes through
Pilot hole.
Compared with prior art, the utility model has the beneficial effects that: it is in die sinking, oblique top is moved upwards, and drives edge
Needle moves upwards, and in the process, one of end of pin can be limited with the jack hole inner wall in lower template, thus pin
Only there is the trend moved upwards, side-to-side movement is limited, and is detached from upwards with the back-off on product.And it moves out and wears in pin
After connecing hole, oblique top is continued up, and during moving upwards, pin has the trend towards medial motion at this time, thus with
Product is thoroughly detached from, and convenient for demoulding, is hardly damaged product.

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model:
A kind of mold demoulded convenient for bottom end pin 60 as shown in Figure 1, Figure 2 and shown in Fig. 3, including cope plate 10, lower die
Plate 20, oblique top 50, pin 60 and ejecting mechanism, cope plate 10, lower template 20 and bottom plate 30 are from top to bottom set gradually, and
Cope plate 10 and lower template 20 are installed on bottom plate 30.Above-mentioned cope plate 10 can be transported towards close to or far from lower template 20
It moves to mold or be opened, cope plate 10 and lower template 20 are used for the shape forming cavity in molding.
Jack hole 21 is specifically equipped in lower template 20, the top of oblique top 50 is movable to be connected in jack hole 21, is being pushed up
Out under the action of mechanism, oblique top 50 can be moved upwards, and oblique top 50 gradually slopes inwardly from the bottom to top.In addition, above-mentioned pin
60 middle-ends are articulated in the top of oblique top 50, make one end of pin 60 by oblique top 50 outside stretch out, and for molding when by
Type chamber is protruded into be formed and be buckled in the bottom end of product.And the other end of pin 60 is stretched out by the inside of oblique top 50, and in die sinking
It is slidably matched with the inner wall of jack hole 21.
When on the basis of the said structure, using the mold demoulded convenient for bottom end pin 60 of the utility model, cope plate 10,
Lower template 20, bottom plate 30 are mountable on the body of mold, the driving mechanism on the body of mold can drive cope plate 10 to
Lower template 20 move downward, in molding, pin 60 can be tied by the end stretched out on the outside of oblique top 50 in the intracavitary molding back-off of type
Structure.In die sinking, oblique top 50 is moved upwards, and pin 60 is driven to move upwards, in the process, one of end of pin 60
It can be limited with 21 inner wall of jack hole in lower template 20, thus pin 60 have the trend moved upwards, side-to-side movement quilt
Limitation is detached from the back-off on product upwards.And after pin 60 moves out jack hole 21, oblique top 50 continues up, upward
During movement, pin 60 has the trend towards medial motion at this time, to thoroughly be detached from product, convenient for demoulding, no
Product easy to damage.
Preferably, the ejecting mechanism in the present embodiment includes ejector retainner plate 40, and ejector retainner plate 40 is mounted on bottom plate 30, the top
Needle plate 40 can move under the drive of external force towards close to or far from lower template 20, and the bottom end of above-mentioned oblique top 50 is installed on thimble
On plate 40.In this way, ejector retainner plate 40 can be jacked up upwards by external external force in die sinking, oblique top 50 can be driven to jack up upwards,
To drive pin 60 to move upwards.
Further, mounting blocks 41 can be equipped on ejector retainner plate 40, sliding slot 411, oblique top 50 are equipped on mounting blocks 41
