Technical Field

[0001] The present invention belongs to the technical field of mold positioning, and particularly relates to an automatic spraying positioning tooling for a hub mold. Background Art

[0002] During the automatic spraying process of a hub mold, precise positioning cannot be achieved. Each time the mold tooling has a deviation, resulting in spraying sagging, water marks, uneven thickness, and inconvenient operation for employees. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides an automatic spraying positioning tooling for a hub mold.

[0004] The present invention is realized through the following technical solutions: An automatic spraying positioning tooling for a hub mold, including a tooling table, and a tooling plate is installed on the top of the tooling table. The feature is that: positioning keys are respectively arranged at the four corners of the tooling plate, and the positioning keys are used to be adapted to the positioning key grooves at the bottom of the lower mold. Two circular grooves are opened on one side of the tooling plate, and two oval grooves are opened on the other side of the tooling plate. The circular grooves and the oval grooves are used to insert the guide posts of the upper mold. The positioning keys are also used to be adapted to the positioning key grooves at the bottom of the side mold, and the side mold is tightly attracted by a magnet, and the magnet is placed between the side template and the lower side template.

[0005] The included angle between the positioning key and the edge of the tooling plate is 45°.

[0006] The cross-section of the positioning key is an isosceles trapezoid.

[0007] A manual switch knob is arranged on the side of the magnet.

[0008] The beneficial effects of the present invention are: the spraying positioning function can be realized, and different-sized molds are compatible; the mold is effectively fixed, and the safety factor is improved; the problem of uneven spraying thickness of the mold is solved, and the temperature field of the mold is controlled by the spraying film thickness, and the product performance is improved. Brief Description of the Drawings

[0009] The following further describes the present invention with reference to the drawings.

[0010] Attached Figure 1 is a schematic structural diagram of the present invention; Attached Figure 2 is a schematic diagram of the upper mold positioning of the present invention; Attached Figure 3 is a schematic diagram of the lower mold positioning of the present invention; Attached Figure 4 is a schematic diagram of the side mold positioning of the present invention; In the figure, 1 is a tooling table, 2 is a tooling plate, 3 is a positioning key, 4 is a lower die, 5 is a positioning key groove, 6 is a circular groove, 7 is an oval groove, 8 is an upper die, 9 is a guide pillar, 10 is a side die, 11 is a magnet, 12 is a side template, 13 is a lower side template, and 14 is a manual switch knob. Detailed implementation mode

[0011] The attached drawing is a specific embodiment of the present invention. This embodiment includes a tooling table 1. A tooling plate 2 is installed on the top of the tooling table 1. Positioning keys 3 are respectively arranged at the four corners of the tooling plate 2. The positioning keys 3 are used to be adapted to the positioning key grooves 5 at the bottom of the lower die 4. Two circular grooves 6 are opened on one side of the tooling plate 2, and two oval grooves 7 are opened on the other side of the tooling plate 2. The circular grooves 6 and the oval grooves 7 are used to insert the guide pillars 9 of the upper die 8. The positioning keys 3 are also used to be adapted to the positioning key grooves 5 at the bottom of the side die 10. The side die 10 is tightly attracted by a magnet 11. The magnet 11 is placed between the side template 12 and the lower side template 13. The included angle between the positioning key 3 and the edge line of the tooling plate 2 is 45°. The cross-section of the positioning key 3 is an isosceles trapezoid. A manual switch knob 14 is arranged on the side of the magnet 11.

[0012] With the automatic spraying positioning tooling for the hub mold of the present invention, the lower die 4 is positioned according to the 45-degree key groove. The lower die 4 is equipped with a 45° positioning key groove 5 by itself. There are 4 positioning keys 3 under all mold frames, and their positions are fixed. Only the lengths of the keys are different and they are made into trapezoidal strips, which can be compatible with different sizes of molds to achieve central positioning, and the tooling table has a hollowed-out and weight-reducing design. The upper die 8 is accurately positioned through the guide pillars 9 and positioning holes (with inclined mouth guiding). According to the spacing and size of the 4 guide pillars 9, a circular groove 6 is designed on one side corresponding to the diameter of the mold guide pillar 9, and an oval groove 7 is designed on the other side, which can be compatible with different sizes of molds from 12 to 22 inches. A 60-degree taper is designed on the upper edge to facilitate the hoisting operation of the mold. The side die 10 is designed with a sunk platform according to the on-site hoisting method. The side die 10 adopts the magnet 11 to attract and tighten, and the embedded magnet 11 ensures that the side die 10 is fixed firmly. The lower side template 13 adopts the 45-degree key design of the mold, and can be used in any combination with the top and bottom tooling at any time.
