AI Technical Summary
Existing technologies struggle to effectively process sealing rings with inverted V-shaped cross-sections, which can easily cause sharp corner damage during demolding.
The upper and lower molds are used for parting at an angle, with a 0.05mm straight section at each parting point to avoid sharp corners. The upper core and upper mold are used with an interference fit to ensure that the V-ring can be smoothly ejected.
This reduces damage and scratches to the sealing ring during the mold opening process and improves the mold parting effect.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to sealing ring processing die technical field, especially, it relates to a V type ring die. BACKGROUND
[0002] The common type of V type ring is a right V type in cross section, and the V type ring with the right V structure has a mature die design and parting. However, when the cross section is an inverted V shape (the shape is shown as: <), due to the limitation of avoiding the sealing surface during parting, the general parting has the problems of being difficult to process or causing the stripping extrusion injury. SUMMARY
[0003] The utility model discloses the purpose of improving the deficiency of prior art and providing a V type ring die suitable for the sealing ring with inverted V type cross section and avoiding the sharp angle.
[0004] The utility model discloses the purpose is realized in this way, a V type ring die, including upper die, upper die core and lower die, its characterized in that the parting position of upper die, lower die is on the inclined plane, and the straight line section of upper die, lower die is all in the parting position, and the straight line section of upper die is horizontal line, and the straight line section of lower die is vertical line.
[0005] In order to further realize the purpose of the utility model, the length of the straight line section can be 0.05mm.
[0006] Compared with prior art, the utility model has the following remarkable features and positive effects: the utility model adopts the parting of upper die and lower die on the inclined plane, and the 0.05mm straight section of upper die and lower die is all in the parting position, avoids the sharp angle, the die parting of the utility model reduces the radial compression rate when the upper die is stripped, and can prevent the damage and scratch of rubber caused by excessive extrusion during the stripping process of the sealing ring. BRIEF DESCRIPTION OF DRAWINGS

[0009] In the drawing: 1, upper die, 2, upper core, 3, V type ring, 4, lower die, 5, inclined plane. DETAILED DESCRIPTION
[0010] A die of V type ring, referring to Figure 1 , Figure 2The upper die 1, the upper core 2 and the lower die 4 are assembled in a conventional manner, the parting position between the upper die 1 and the lower die 4 is in the middle position of the inclined surface 5 of the V-shaped ring 3, the upper die 1 and the lower die 4 have straight lines at the parting position, the straight line of the upper die 1 is a horizontal line, the straight line of the lower die 4 is a vertical line, and the length of the two straight lines is 0.05 mm; the parting position between the lower die 4 and the upper core 2 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the upper die 1 is at the sharp corner of the upper end of the V-shaped ring 3, so that the cavity of the upper end of the V-shaped ring 3 is difficult to process, the upper core 2 and the upper die 1 are assembled together through interference fit, the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the parting position between the upper core 2 and the lower die 4 is at the sharp corner of the lower end of the V-shaped ring, and the
Claims
1. A V-ring die comprising an upper die, an upper die core and a lower die, characterized in that The parting position of the upper die and the lower die is on a slope, and the upper die and the lower die each have a straight line segment at the parting position.
2. A V-ring die according to claim 1, characterised in that The length of the straight line segment is 0.05 mm.
