Abstract
The utility model discloses a kind of die casting mould core positioning regulating structure, comprise the first core and the second core of being located at docking engaged with one another in die cavity, described first core has location docking structure with the contact jaw that coordinates of the second core, the abutment end of described first core and/or the second core is provided with elastic component, under the elastic force effect of described elastic component, described first core coordinates contact jaw intimate contact with one another with the second core, this die casting mould core positioning regulating structure by being provided with elastic component in the abutment end of the first core and/or the second core, then when mould closes, what can ensure on the one hand the first core and the second core coordinates contact jaw intimate contact with one another, formation good location is docked, on the other hand, because elastic component exists the thermal expansion deformation amount that elastic deformation amount can balance out again the first core and the second core, thus the long core temperature distortion avoiding close contact to be formed.
Description
Technical field
the utility model relates to mould Accessory Members technical field, particularly a kind of core positioning regulating structure of die casting.
Background technology
in mould-forming process, when needs mold and have poroid workpiece, need to arrange core in die cavity; Two corresponding cores are set under certain conditions often, when mould closes, two cores cooperatively interact and dock the complete long core of formation one, when two cores cooperatively interact docking, in order to prevent the reasons such as molten metal impact from causing long core flexural deformation etc., often need the version being arranged to by the contact jaw of two cores locate each other.Due to reasons such as thermal expansions, two cores, when cooperatively interacting docking, contact with each other between end and need to leave a certain amount of gap, as shown in Figure 1.But the existence in this certain amount of gap often can cause again two cores to coordinate butt junction location to lose efficacy, and affects forming quality of products.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the reliable die casting mould core positioning regulating structure of two core butt junction location.
For solving the problems of the technologies described above adopted technical scheme: a kind of die casting mould core positioning regulating structure, comprise the first core and the second core of being located at docking engaged with one another in die cavity, described first core has location docking structure with the contact jaw that coordinates of the second core, the abutment end of described first core and/or the second core is provided with elastic component, under the elastic force effect of described elastic component, described first core coordinates contact jaw intimate contact with one another with the second core.
Further, described elastic component is butterfly spring.
Further, the cooperation contact jaw of described first core is provided with positioning boss, and the cooperation contact jaw of described second core is provided with the location dimples coordinating with positioning boss and locate.
Beneficial effect: this die casting mould core positioning regulating structure by being provided with elastic component in the abutment end of the first core and/or the second core, then when mould closes, what can ensure on the one hand the first core and the second core coordinates contact jaw intimate contact with one another, forms good location and docks; On the other hand, because elastic component exists the thermal expansion deformation amount that elastic deformation amount can balance out again the first core and the second core, thus the long core temperature distortion avoiding close contact to be formed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the schematic diagram that in prior art, two cores coordinate;
Fig. 2 is the structural representation of the utility model embodiment.
Detailed description of the invention
As shown in Figure 2, the utility model relates to a kind of die casting mould core positioning regulating structure, comprise the first core 10 and the second core 20 being located at docking engaged with one another in die cavity, first core 10 has location docking structure with the contact jaw that coordinates of the second core 20, the abutment end of the first core 10 and/or the second core 20 is provided with elastic component 30, under the elastic force effect of elastic component 30, the first core 10 coordinates contact jaw intimate contact with one another with the second core 20.
In the present embodiment, the cooperation contact jaw of the first core 10 is provided with positioning boss 11, second core 20 coordinates contact jaw to be provided with location dimples 21, and when the mold is closed, the positioning boss 11 of the first core 10 is embedded in the location dimples 21 of the second core 20 and completes the docking of core location.
Wherein, elastic component 30 selects butterfly spring, this butterfly spring is arranged in the abutment end of the second core 20, the abutment end of the first core 10 can certainly install butterfly spring, or in the abutment end of the first core 10 and the second core 20, all butterfly spring is installed, under the resilient force of butterfly spring, when mould closes, first core 10 coordinates contact jaw intimate contact with one another with the second core 20, to ensure that the first core 10 docks with the second core 20 good location; When type cavity temperature raises, because butterfly spring exists certain elastic deformation amount, the thermal expansion deformation amount of the first core 10 and the second core 20 can be balanced out, thus the long core temperature distortion avoiding close contact to be formed bends.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
