Description
Technical Field
The utility model relates to a mould die-casting technical field, especially a take exhaust structure's wheel hub mould positioner.
Background
The method for positioning the upper mold and the lower mold of the hub mold in a mold closing mode, which is widely applied in the market at present, is characterized in that a limiting height is arranged in an upper mold window and a lower mold window of the hub mold, and the height of a limiting table is used as a positioning basis for mold closing. With the diversified development of the hub modeling design, the design of the hub modeling at the window is more and more complex and irregular, and the traditional upper and lower mold clamping and positioning mode is not practical.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a take exhaust structure's wheel hub mould positioner.
The utility model provides a technical scheme that its technical problem adopted is:
a hub die positioning device with an exhaust structure comprises an upper die and a lower die, wherein a hub cavity is arranged between the upper die and the lower die, and a detachable positioning block is arranged between the upper die and the lower die; and an exhaust groove is formed in the side edge of the positioning block.
As an embodiment of the utility model, the cross-section of air discharge duct is the V font structure, wherein the cross-section contained angle of air discharge duct is beta, and beta is greater than or equal to 60 degrees and is less than or equal to 150 degrees, the cross-section width of air discharge duct is d3, and 1mm is less than or equal to d3 and is less than or equal to 4 mm.
As an embodiment of the utility model, the locating piece passes through the bolt to be installed on the lower mould. The utility model has the advantages that: through setting up dismantled and assembled locating piece design in last lower mould die joint department, more be applicable to the parting position and have complicated figurative product, increased exhaust function through the air discharge duct design simultaneously, improve compound die efficiency.

The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic view of the mold assembly of the present invention;
FIG. 2 is a perspective view of the positioning block of the present invention;
fig. 3 is a sectional view of the positioning block of the present invention;
fig. 4 is a top view of the positioning block of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1, the hub mold positioning device with the exhaust structure includes an upper mold 100 and a lower mold 200, and a hub cavity 300 is disposed between the upper mold 100 and the lower mold 200. And (3) die-casting the upper die 100 and the lower die 200 after die assembly to obtain a hub casting.
A detachable positioning block 400 is arranged between the upper die 100 and the lower die 200, namely, the traditional upper and lower die limit table structure is eliminated, and the positioning block 400 is added at the parting surface of the upper and lower dies to be used as an insert structure. The specific position of the positioning block 400 can refer to the middle section of the parting plane shown by the upper die and the lower die in fig. 1, and the position can also be flexibly designed according to the shape characteristics and parting position requirements of a workpiece to match various products with complex shapes.
Referring to fig. 2, the exhaust groove 410 is formed in the side edge of the positioning block 400, so that the exhaust groove is more suitable for exhausting gas generated in the process of closing the upper die and the lower die on the premise of processing of closing and positioning the complex-shaped die, the exhaust function is enhanced, the die closing efficiency is improved, and the production efficiency is further improved.
The positioning block 400 is mounted on the lower mold 200 through the bolt 500, and can be replaced at any time after being worn in the using process, thereby achieving the purpose of reducing the maintenance cost of the mold. Moreover, the design reduces the milling amount of the traditional matching positioning structure, and improves the process of drilling holes (corresponding to mounting holes of the bolts 500) on the lower die 200, thereby saving the cost. Alternatively, the bolt 500 is a standard socket head heat resistant bolt. Referring to fig. 3, as an optional mode, the upper side of the positioning block 400 is a truncated cone, the lower side is a cylinder, as a reference, the width of the bottom of the positioning block 400 is D, D is 20mm or more and 50mm or less, the widths of the upper side and the lower side of a bolt hole in the positioning block 400 are D1 and D2 respectively, D1 and D2 size reference bolt matching specification standards, the height of the truncated cone part on the upper side of the positioning block 400 corresponding to the outer side of the exhaust groove 410 is H1, the height of the inner side of the exhaust groove 410 corresponding to the inner side of the exhaust groove 410 is H1, the height of the cylindrical part on the lower side of the positioning block 400 corresponding to the outer side of the exhaust groove 410 is H2, the height of the inner side of the exhaust groove 410 is H2, H1 is 8mm or more, H2 is 0mm or more, H1 is 4mm or more and H2, the radius.
Referring to FIG. 4, the section of the exhaust groove 410 is a V-shaped structure, wherein the included angle of the section of the exhaust groove 410 is beta, beta is larger than or equal to 60 degrees and smaller than or equal to 150 degrees, the width of the section of the exhaust groove 410 is d3, and d3 is larger than or equal to 1mm and smaller than or equal to 4 mm. The radius r of a rounded corner at the bottom end of the V-shaped part of the exhaust duct 410 is more than or equal to 0mm and less than or equal to 1 mm.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
