Abstract
A kind of big stroke side core-pulling mould is the utility model is related to, by a snap device with free gap, core-pulling mechanism is connected on side slide block, realizes core-pulling mechanism with lateral guide rod compound action on side slide block.During die sinking, first, by the driving side slide block movement of lateral guide rod, its active force is larger, realizes side core_pulling stress by departing from moulding, and now side slide block is movable independently of core-pulling mechanism by the free gap of snap device；Then, core-pulling mechanism detaches moulding with a less active force, low speed.
Description
Technical field
The utility model belongs to technology of die manufacturing field, and in particular to a kind of big big stroke of side core_pulling core pulling stroke
Side core-pulling mould.
Background technology
In sanitaryware, it need to generally be related to the siphunculus that a kind of length is much larger than internal diameter.Connect as shown in figure 1, the figure is bathroom
The connecting tube 1 connect, it is the main part of an elongated cylindrical.
In the production process of the connecting tube 1, the inner chamber of the main part need to be molded by side core_pulling, and then side core-pulling is complete
Into die sinking.
Because main part inner chamber is longer, its side core_pulling and moulding bonded area are big, and being firmly combined with property is strong, and (1) is preferred,
Great lateral force is needed, could realize that side core_pulling departs from moulding；(2) secondly as inner chamber is longer, side core-pulling row
Journey is larger.
For the problem, generally use oil cylinder or cylinder carry out side core-pulling, and are risen according to above mentioned problem, oil cylinder or cylinder
Stage beginning need to be loaded onto maximum pull state, realize the demoulding.However, required core pulling pulling force very little after the demoulding, this kind of technical scheme
Cause side core_pulling a greater impact active force to be present, easily wear or moulding of wounding.
The content of the invention
The utility model aims to provide a kind of big stroke side core-pulling mould, is stranded with solving existing slender cavity side core-pulling
The problem of difficult, moulding is easily injured or abraded.
Concrete scheme is as follows：A kind of big stroke side core-pulling mould, including dynamic model and cover half, the dynamic model, which is provided with, to be used to pacify
Fill side core_pulling side slide block, the cover half be provided with to should cover half lateral guide rod；A tube bundle extracting machine is additionally provided with the dynamic model
Structure, the core-pulling mechanism are connected to the side slide block by a connecting rod；The free end of the connecting rod coordinates shape with the side slide block
Into a snap device；On side slide block die sinking direction, the snap device has certain free gap, makes the side slide block
Be connected in the connecting rod and can with respect to the connecting rod in limited travel it is movable.
Further, the core-pulling mechanism is an oil cylinder or cylinder, and the connecting rod is piston rod.
Further, one end on the side slide block away from side core_pulling is provided with an inclined plane part, corresponding, is set on the cover half
There is a briquetting coordinated with the inclined plane part；During matched moulds, the briquetting acts on the inclined plane part, realizes that the position of side slide block is consolidated
It is fixed.
Further, a dovetail groove, the free end of the connecting rod are provided with towards the side of core-pulling mechanism on the side slide block
Provided with a limited block that can be snapped connection with the dovetail groove, the limited block is located in the dovetail groove to cooperatively form the fastening machine
Structure；The limited block length direction is less than the dovetail slot length, and then realizes the snap device and have certain free gap.
Further, the free gap is more than or equal to 5 millimeters.
Beneficial effect：The technical solution of the utility model, by a snap device with free gap, by core-pulling mechanism
It is connected on side slide block, realizes core-pulling mechanism with lateral guide rod compound action on side slide block.It is first during die sinking
First, by the driving side slide block movement of lateral guide rod, its active force is larger, realizes side core_pulling stress by departing from moulding, this
When side slide block by the free gap of snap device independently of core-pulling mechanism activity；Then, core-pulling mechanism is with a less work
Firmly, low speed detaches moulding.

Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to shown in Fig. 2 to Fig. 4, this embodiment offers a kind of big stroke side core-pulling mould, including dynamic model 2 and cover half
1, the dynamic model 2 is provided with side slide block 3, and installation is by side core_pulling 21 on the side slide block 3；Corresponding, the cover half 1 is provided with side
To guide rod (not shown), the side slide block 3 is provided with an oblique cutting hole 31, and the lateral guide rod coordinates with the oblique cutting hole 31, with
Realize side core-pulling and the matched moulds movement of side slide block 3.
A core-pulling mechanism 4 is additionally provided with the dynamic model 2, in this embodiment, the core-pulling mechanism 4 can be an oil cylinder or gas
The piston rod of cylinder, the oil cylinder or cylinder is connected to side slide block 3 as a connecting rod 41.
Specifically, the free end of the connecting rod 41 cooperatively forms a snap device with the side slide block 3：
A dovetail groove 311 is provided with towards the side of core-pulling mechanism 4 on the side slide block 3, the free end of the connecting rod 41 is set
