Description
Technical field
The present invention relates to technical field of mold more particularly to a kind of lifting lug molds of easy mold release.
Background technique
Existing lifting lug mold is limited by the structure, and after die sinking, product is stayed on mold core, and demoulding is extremely inconvenient urgently to be changed
Into.
Summary of the invention
Technology based on the above background, the present invention propose a kind of lifting lug mold of easy mold release.
The invention proposes a kind of lifting lug molds of easy mold release, comprising: upper mold, middle mould and lower die, in which:
Middle mould is equipped with die cavity up and down, and the inner wall of the die cavity is equipped with the groove being recessed to its outer wall direction, described
Groove is the annular groove being circular layout around die cavity；
Lower die is equipped with the mold core that is secured to, under molding state, the upper mold, middle mould and lower die from top to bottom sequentially according to
Secondary arrangement simultaneously abuts each other, and mold core protrudes into die cavity and cooperates with die cavity with shape forming cavity.
Preferably, groove is located between the both ends of die cavity.
Preferably, the cross-sectional shape of groove is C-shaped.
Preferably, further include runner plate, molding state flow down guidance tape be located at upper mold top simultaneously and upper mold against.
In the present invention, by the way that the groove being recessed to its outer wall direction is arranged on the mould intracavity wall of middle mould, so that opening
It when mould, after mould is lifted in the middle, is limited by groove, the intracavitary product of type is directly taken up by the middle mould of upper lift, when demoulding, only needs
Product is ejected, so as to effectively improve the examination efficiency of production line.

Specific embodiment
In the following, technical solution of the present invention is described in detail by specific embodiment.
As shown in Figs. 1-5, Fig. 1 is a kind of top view of the lifting lug mold of easy mold release proposed by the present invention；Fig. 2 is in Fig. 1
The partial sectional view of C-C；Fig. 3 is a kind of exploded view of the lifting lug mold of easy mold release proposed by the present invention；Fig. 4 is that the present invention proposes
A kind of easy mold release lifting lug mold described in middle mould partial enlarged view；Fig. 5 is a kind of hanging for easy mold release proposed by the present invention
It is main described in ear mold that hopper and second level is drawn to draw the structural schematic diagram of hopper.
Referring to Fig.1-2, the embodiment of the present invention propose a kind of easy mold release lifting lug mold, comprising: runner plate 1, upper mold 2,
Middle mould 3 and lower die 4, in which:
Middle mould 3 is equipped with die cavity up and down, and the inner wall of the die cavity is equipped with the groove 31 being recessed to its outer wall direction, institute
Stating groove 31 is the annular groove being circular layout around die cavity.Lower die 4 is equipped with the mold core 41 being secured to, described under molding state:
Runner plate 1, upper mold 2, middle mould 3 and lower die 4 are from top to bottom sequentially sequentially arranged and abut each other, and mold core 41 protrudes into die cavity simultaneously
Cooperate with die cavity with shape forming cavity.
It when demoulding, is segmented and is opened using press, one section of operation of press promotes runner plate 1 and upper mold 2, and product is all stayed at this time
It stays in middle mould 3 and type that lower die 4 cooperatively forms is intracavitary；When two sections of operation press lift middle mould 3, since middle 3 inner wall of mould increases
Groove, so that the intracavitary product of type with lifting on middle mould 3 is detached from lower die 4；When mould 3 is raised to certain height in the middle,
The stripper of matching is placed at the positioning of lower die 4,3 downlink of middle mould for just rising to height is driven by operation press, with
The generation of downlink movement, the ejection of stripper partially contacted with the product taken up by middle mould 3；Then middle mould 3 continues traveling downwardly, and makes
It obtains the product in die cavity and is all demolded device ejection, due between various intracavitary product is in forming being connected by Jiao Dao
It is connected together, this takes out product disposably.
From the foregoing, it will be observed that the present invention by be arranged on the mould intracavity wall of middle mould 3 to its outer wall direction be recessed groove 31, from
And when making die sinking, it after mould 3 is lifted in the middle, is limited by groove 31, the intracavitary product of type is directly by 3 band of middle mould of upper lift
It rises, when demoulding, it is only necessary to eject product, so as to effectively improve the examination efficiency of production line.
In addition, groove 31 is located between the both ends of die cavity in the present embodiment, and the cross-sectional shape of groove 31 is C-shaped, with
Facilitate the ejection of product.
In addition, injecting glue sprue a is formed between runner plate 1 and upper mold 2, between upper mold 2 and middle mould 3 under molding state
Form injecting glue runner b.It is equipped in runner plate 1 for sizing material to be imported to the main injection nozzle 5 in injecting glue sprue a, in upper mold 2
It is equipped with for by the secondary injection mouth 6 of the sizing material importing type chamber in injecting glue sprue a.In injecting glue sprue a and it is located at main note
The lower section of nozzle 5 is equipped with extension and the main drawing hopper c coaxially arranged with main injection nozzle 5 from top to bottom, and the main bottom for drawing hopper c
Internal diameter is greater than the bore of its top port.It is equipped in injecting glue runner b and positioned at the lower section of secondary injection mouth 6 and extends from top to bottom
And hopper d is drawn with the coaxially arranged second level of secondary injection mouth 6, and second level draws the bottom inner diameter of hopper d to be greater than its top port
Bore (as shown in Figure 5).When the setting of above structure is so that be opened, it can use main drawing hopper c and internal sizes limited and are produced
Raw pulling force breaks the sizing material in main injection nozzle 5, so that the waste material in injecting glue sprue a is all in the upper surface of upper mold 2；It utilizes
The pulling force that second level draws hopper d to limit and generate internal sizes breaks the sizing material in secondary injection mouth 6, so that injecting glue runner b
Interior waste material all in the upper surface of middle mould 3, greatly facilitates producers and removes waste material work, so that production efficiency is significantly
It improves.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
