Description
Technical field
The present invention relates to the mould structure technical fields that sand core manufacture uses.
The invention further relates to the manufacturing methods of the sand core with irregular structure.
Background technology
Core mold forms sand core by penetrating sand into mold in a mold, when penetrating sand, can fill up sand in cavity rapidly.
And when the part of sand core is irregular abnormity, the cavity of the part profiled section is also irregular, its knot of cavity internal cause
The difference of structure causes local profiled shape to interfere what be can not be successfully to make taking-up in mold with mold.Cause sand core part needs
Second of local sand core part of mold and making, the sand core part that local sand core part is manufactured with first time again later are made again
It carries out being assembled to form complete sand core.Not only production cost greater efficiency is low for the manufacture of such sand core, and the matter of sand core
Amount has very big potential problems.Easy to produce casting defect and quality problems.In order to avoid with solve the problems, such as this.Therefore it needs a kind of new
Technical solution to solve the above problems.

The side of cavity, which tilts, to be extended, which includes two parallel interdigital portions, and the fork pockets of lengthwise is formed between two interdigital portions；
Second module includes forming the second cavity of cavity and from positioned at the second assembly section of the second cavity side, second assembly
There is two sliding rails disposed in parallel, the sliding block between two sliding rails in area, the both sides of the sliding block be equipped with respectively with
The sliding slot of two sliding rails cooperation, by sliding slot, the sliding block moves under the constraint of sliding rail, the one end of the sliding block towards the second cavity
It is extended with convex block；The convex block is as the part for forming cavity after the first module and the cooperation of the second module；The slider surface pair
Equipped with the fluting through the sliding block, it is equipped with guiding axis in the fluting, when the first module and the cooperation of the second module, which inserts
In the fork pockets for entering the shift fork, guiding axis is moved in fork pockets and is slided with respect to sliding rail with movable slider.
Advantageous effect：Compared with the existing technology, mold provided by the invention will be to form the cavity of sand core irregular shape
Component part is coordinated with that can be formed with movable sliding block by the inclined guide of a kind of shift fork and sliding block, and sliding block is enable to exist
With disengaging of the sand core without interference after formation sand core, i.e., when the first module and the second module are detached from, sliding block is in shift fork and guiding axis
Inclined guide under moved to the direction far from sand core to be detached from without interference with sand core along sliding rail, even if to which sand core has and does not advise
Then shape also can once be made and will not interfere with mold in coring.
The present invention also provides the technical solutions for the method for using above-mentioned mold manufacturing sand core, i.e.,：
Include the following steps：
(1), the sliding slot of sliding block is separately mounted on two sliding rails；
(2), the first module and the second module being connected to each other, the guiding axis of the sliding block is inserted into the fork pockets of shift fork at this time,
And it is close with the first module and the second module, sliding block with guiding axis under the guiding of fork pockets on sliding rail to the second cavity
It is close；
(3), the first module is docked completely with the second module, and the front end of sliding block is located in cavity at this time and sliding block forms cavity
A part for interior shape；Sand is penetrated into cavity forms sand core；
(4), it penetrates after the completion of sand, the first module and the second module is separated from each other, sliding block is as guiding axis is in fork pockets at this time
Guiding under on sliding rail to the second cavity far from direction slide, i.e., sliding block be detached from cavity in formed sand core；Then it further takes out
Sand core.
By the method for above-mentioned manufacture sand core, the proper use of mode of mold in the present invention is given, can once be made
It will not interfere with mold at the sand core with irregular shape and in coring.
