Abstract
The utility model discloses three plate compression mods of one kind and opens limiting mechanism, including preceding mould, middle mould and rear mold, and middle mould is opened limiting structures by one or more with the side of rear mold and connected, when preceding mould and middle mould separate, the separation of mould and rear mold in unlatching limiting structure limitation.The utility model use open limiting structure, the unlatching limiting mechanism can before opening mould when limitation in mould and rear mold unlatching, so that preceding mould, middle mould and rear mold is successively opened from top to bottom.This unlatching limiting structure can prevent the uneasy sequence in die sinking from opening, cause between mold damage it is bad with product.
Description
Technical field
The utility model relates to die casting mold structure, in particular to a kind of three plate compression mods open limiting mechanism.
Background technique
Currently, existing mold has two plates and three plates or more plates to need to consider cephacoria after the molding of compression mod die-cast product
Opening sequence, due to the compression mod of three plates or more plates combination when, need by from top to bottom sequence open, but due to combination
The attachment force of preceding middle rear mold be not fixed, it cannot be guaranteed that the sequence opened, when die sinking, is easy to appear the feature that middle mould is first opened, in
If mould is first opened, be easy to cause middle mould open rise during the danger that falls.Molds and products are caused to damage.
Utility model content
The purpose of this utility model is in view of the above drawbacks of the prior art, to provide a kind of three plate compression mods unlatching limitation machine
Structure, the unlatching limiting mechanism can before opening mould when limitation in mould and rear mold unlatching, enable preceding mould, middle mould and rear mold from
Top to bottm is successively opened.
For the drawbacks described above for solving the prior art, technical solution provided by the utility model is: a kind of three plate compression mods are opened
Open limiting mechanism, including preceding mould, middle mould and rear mold, limiting structures are opened by one or more in the side of the middle mould and rear mold
When connection, the preceding mould and middle mould separate, the separation for opening mould and rear mold in limiting structure limitation.
A kind of improvement of limiting mechanism is opened as three plate compression mod of the utility model, the unlatching limiting structure includes solid
The upper blocking seat for being scheduled on the middle mould side and the lower deck for being fixed on the rear mold side, it is convex that the lower end of the upper blocking seat stretches out one
It rises, the upper end of the lower deck is equipped with a groove, is respectively equipped with spring fixed hole in the two sidewalls of the groove, the spring is solid
Determine to be fixed with a spring in hole, the end of the spring is equipped with a fixed ball or fixed pin, the two sides of the protrusion are set respectively
There is arc groove.
A kind of improvement of limiting mechanism is opened as three plate compression mod of the utility model, the half of the fixed ball is embedded in institute
It states in arc groove.
A kind of improvement of limiting mechanism is opened as three plate compression mod of the utility model, when the middle mould and rear mold separate,
The spring is separated by the effect for being opened external force, the fixed ball with the arc groove.
A kind of improvement of limiting mechanism, the mould opening force of the middle mould and rear mold are opened as three plate compression mod of the utility model
Degree is greater than the elastic force of the spring.
A kind of improvement of limiting mechanism, the upper blocking seat and the lower deck are opened as three plate compression mod of the utility model
Fixed by screw locking.
Compared with prior art, the utility model has the advantages that: the utility model use open limiting structure, the unlatching
Limiting mechanism can before opening mould when limitation in mould and rear mold unlatching, enable preceding mould, middle mould and rear mold from top to bottom according to
Secondary unlatching.This unlatching limiting structure can prevent the uneasy sequence in die sinking from opening, and cause damaging between mold and product
It is bad.
Detailed description of the invention
Just the utility model and its beneficial technical effect are made with specific embodiment with reference to the accompanying drawings below further detailed
Thin description, in which:
Fig. 1 is the main view of the utility model.
Fig. 2 is to open limiting structure schematic diagram.
Appended drawing reference title: 1, preceding mould 2, middle mould 3, rear mold 4, unlatching limiting structure 41, upper blocking seat 42, lower deck
43, protrusion 44, groove 45, spring fixed hole 46, spring 47, fixed ball 48, arc groove.
Specific embodiment
Just the utility model is further described with specific embodiment with reference to the accompanying drawings below, but the implementation of the utility model
Mode is not limited to this.
As depicted in figs. 1 and 2, a kind of three plate compression mods open limiting mechanism, including preceding mould 1, middle mould 2 and rear mold 3, middle mould
2 and the side of rear mold 3 connected by one or more limiting structures 4 of opening, when preceding mould 1 and middle mould 2 separate, open limiting structure
The separation of mould 2 and rear mold 3 in 4 limitations.After current mould 1 and middle mould 2 separate, then mould 2 and rear mold 3 in separating, mould 2 and rear mold in the middle
When 3 die sinking dynamics is greater than the elastic force of spring, middle mould 2 and rear mold 3 are separated.Enable preceding mould 1, middle mould 2 and rear mold 3 from top to bottom
Successively open.Opening limiting structure can be set in middle mould and rear mold diagonal angle or side around middle mould and rear mold.
Preferably, opening limiting structure 4 includes being fixed on the upper blocking seat 41 of middle 2 side of mould and being fixed on 3 side of rear mold
A protrusion 43 is stretched out in lower deck 42, the lower end of upper blocking seat 41, and the upper end of lower deck 42 is equipped with a groove 44, in the two sides of groove 44
Wall is respectively equipped with spring fixed hole 45, and a spring 46 is fixed in spring fixed hole 45, and the end of spring 46 is equipped with a fixed ball
47 or fixed pin, the two sides of protrusion 43 are respectively equipped with arc groove 48.The end of fixed pin is hemispherical.
Preferably, in the half insertion arc groove of fixed ball 47；Or in the end insertion arc groove of fixed pin, two
Kind frame mode may be implemented.
Preferably, when middle mould 2 and rear mold 3 separate, spring 46 by die sinking external force effect, fixed ball 47 or fixed pin with
