Abstract
The utility model discloses a kind of three inside groove internal expanding type pulled core structures, including cone sliding block A, cone slide block B, valve block B and valve block A, guiding movement is carried out by T-slot connection and pressing plate between each other, the cone slide block B can inside contract connection movement with moving vane block B, the cone sliding block A can inside contract connection movement with moving vane block A, and two inside contract motion stage completion.This pulled core structure when in use, is twitched by external force band mantle slide block B, and valve block B is inside contracted, conceded to valve block A and inside contract space, and it is motionless to bore sliding block A at this time；After cone slide block B moves to certain distance, valve block B, which is inside contracted, not to be continued to inside contract in place, and is kept opposing stationary with cone slide block B and moved together, then bores slide block B with the A movements of mantle sliding block, valve block A is inside contracted, until plastic product is completely fallen off.This pulled core structure is inside contracted using secondary, and increase inside contracts width direction size one-time continuous and uninterruptedly moves, and shortens mold molding time, is saved the production energy, is improved capacity benefit.
Description
Technical field
The utility model belongs to plastic mould field, and in particular to a kind of three inside groove internal expanding type pulled core structures.
Background technology
As China's expanding economy, especially automatic technology are more and more ripe, interior core-pulling die is at modeling
One of general character and the key technology for expecting mold, are mainly used in the plastic part that interior thorax size is more than finish dimensional, such as flared tube
Part, instrument housing, bottle cap, automobile intake stack etc., enable part smoothly, without interferingly from mold core pulling is exited.
Mold producer in China's opens and conducts in-depth research and improve on formula core-pulling die inside in recent years, in the prior art
In, number of patent application 201020226531.X, the utility model patent of entitled " internal expanding type core-pulling die " discloses one kind
Core-pulling die including petaloid core, cone sliding block and pull rod, operation principle are：Cone sliding block moves under external force, sliding block
Planned course make two groups of petaloid cores in sliding groove along different tracks while radially moving, in a limited space
In in core pulling.Internal expanding type pulled core structure design is simple, solves the problems, such as core pulling difficulty, but the core-pulling die due to by
It to the limitation of structure, inside contracts that width dimensions are shorter, is unsuitable for the core pulling technique of long plastic articles mold.
Invention content
The purpose of this utility model is that overcome drawbacks described above existing in the prior art, by using secondary interior
Contracting, increase inside contract width direction size, achieve the purpose that shrink three inside groove abjection products, provide a kind of three inside groove internal expanding types
Pulled core structure.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of three inside groove internal expanding type pulled core structures, packet
Cone sliding block A, cone slide block B, valve block B and valve block A are included, guiding movement is carried out by T-slot connection and pressing plate between each other, it is described
Cone slide block B can inside contract connection movement with moving vane block B, and the cone sliding block A can inside contract connection movement with moving vane block A, and two inside contract
Motion stage is completed.
This pulled core structure when in use, is twitched, valve block B is inside contracted, conceded and inside contract to valve block A by external force band mantle slide block B
Space, cone sliding block A is motionless at this time, and after cone slide block B moves to certain distance, valve block B, which is inside contracted, not to be continued to inside contract in place, and with
Cone slide block B keeps opposing stationary and moves together, then bores slide block B band mantle sliding block A movements, valve block A is inside contracted, until plastic product
It completely falls off.
In general, can reach the above technical solutions conceived by the present invention are compared with the prior art, with
Lower advantageous effect：It is inside contracted using secondary, increase inside contracts width direction size, reaches and shrinks three indents（Slot）Deviate from the mesh of product
, one-time continuous uninterruptedly moves, and shortens mold molding time, saves the production energy, improves the capacity benefit of Shooting Technique.
Description of the drawings
Specific embodiment of the present utility model is further described in detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is a kind of overall structure diagram of three inside grooves internal expanding type pulled core structure of the utility model；
Fig. 2 is a kind of right side view of three inside grooves internal expanding type pulled core structure of the utility model；
In figure：1- bores sliding block A, 2- and bores slide block B, 3- valve block B, 4- valve blocks A.
Specific implementation mode
As depicted in figs. 1 and 2, it is a kind of overall structure diagram and right side view of three inside grooves internal expanding type pulled core structure,
Including cone sliding block A1, cone slide block B 2, valve block B3 and valve block A4, guiding fortune is carried out by T-slot connection and pressing plate between each other
Dynamic, the cone slide block B 2 can inside contract connection movement with moving vane block B3, and the cone sliding block A1 can inside contract connection movement with moving vane block A4,
And two inside contract motion stage completion.
When in use, by two inside contract movement completes core pulling process to this pulled core structure.It is slided first by external force band mantle
Block B2 is twitched, and valve block B3 is inside contracted, conceded to valve block A4 and inside contract space, and it is motionless to bore sliding block A1 at this time；When cone slide block B 2 moves to one
After set a distance, valve block B3, which is inside contracted, not to be continued to inside contract in place, and is kept opposing stationary with cone slide block B 2 and moved together, and then cone is slided
Block B2 band mantle sliding block A1 movements, valve block A4 is inside contracted, until plastic product is completely fallen off.
As it will be easily appreciated by one skilled in the art that the above is only the preferred embodiment of the utility model only, not
For limiting the utility model, any modification made within the spirit and principle of the present invention, equivalent replacement and change
Into etc., it should be included within the scope of protection of this utility model.
