[0047] The present invention provides an optimization processing method before designing an n-type vertical P-section sealing mold, comprising the following steps:

[0048] S1: Observe and analyze the two vertical ends of the n-type vertical P-section seal;

[0049] S101: Measure the cavity thickness at the vertical end;

[0050] S102: Compare the cavity thickness with the compound thickness.

[0051] S2: Measure the length of the two vertical ends and the inner and outer arc lengths of the seal;

[0056] S402: Calculate the difference between the inner and outer arc lengths before and after adjustment, and determine whether the arc length difference is within a specified tolerance range.

[0057] The inner arc length tolerance is ±6.6mm, and the outer arc length tolerance is ±7.2mm.

[0058] Embodiment 1:

[0059] This embodiment provides an optimization method before designing a mold for an n-type vertical P-section seal. Figure 2 As shown, the two outlet ends of the n-shaped rubber seal are in a vertical state, namely the left vertical end 1 and the right vertical end 2, as shown in FIG. Figure 3 As shown in the figure, the left outlet section A and the right outlet section B are symmetrical inverted P-shaped, and the P-shaped section is also vertical. In the early stage of mold design, considering the influence of rubber process operation and mold clamping, the appearance and cross-sectional characteristics of the rubber seal are carefully examined. Without changing the use function and sealing effect of the rubber seal, the external form is changed to achieve the effect of simplifying the mold structure design and simplifying the rubber production process operation, such as Figure 1 As shown, the following steps are included:

[0060] S1: Observe and analyze the two vertical ends of the n-type vertical P-section seal;

[0061] Observation and analysis show that there are no major problems at the upper bend of the seal, and the problems are mainly concentrated at the two vertical ends.

[0062] S101: Measure the cavity thickness at the vertical end;

[0063] The thickness of the cavity here is 2mm.

[0064] S102: Compare the cavity thickness with the compound thickness.

[0065] Since the rubber compound is in an immature state, soft and unformed, and considering that the tolerance of the rubber compound thickness is greater than the gap of 2mm, when operating the mold, whether pushing from top to bottom or from front to back, the vertical surfaces on both sides will make it difficult to close the mold.

[0066] S2: Measure the length of the two vertical ends and the inner and outer arc lengths of the seal;

[0067] The length of the right vertical end 2 is 231.5 mm, the length of the left vertical end 1 is 75.1 mm, the inner arc length is 830.8 mm, and the outer arc length is 907.3 mm.

[0068] S3: According to the measured length, tilt the vertical end outward from the tangent point of the bend and the vertical end;

[0069] According to the operation process analysis of the mold structure design, the right vertical end 2 is tilted 3° to the right from the tangent point, and the left vertical end 1 is tilted 3° to the left from the tangent point. The appearance of the adjusted seal is as follows: Figure 4 shown.

[0070] S4: Determine whether the adjusted seal meets the standards.

[0071] S401: Measure the inner and outer arc lengths of the adjusted seal;

[0072] After adjusting the angle, consider the outer length of the rubber seal and measure the adjusted inner and outer arc lengths, see Table 1.

[0073] S402: Calculate the difference between the inner and outer arc lengths before and after adjustment, and determine whether the arc length difference is within a specified tolerance range.

[0074] The difference in arc length between the inner and outer sides is calculated, as shown in Table 1. According to the HB8233-2002 M3 grade tolerance standard for rubber seals, the difference in arc length before and after adjustment is within the tolerance range and has minimal impact.

[0075] Table 1 Data analysis of n-shaped vertical P-section rubber seal before and after optimization

[0076] name Optimized front arc length (mm) Optimized arc length (mm) Arc length difference (mm) Arc length tolerance (mm) Inside edge 830.8 831.9 +1.1 ±6.6 Outside edge 907.3 907.1 -0.2 ±7.2

[0077] After the rubber seal is optimized, the impact on mold operation is as follows: Figure 5 and Figure 6 As shown, the mold structure before optimization is as follows Figure 5 As shown, before optimization, both ends of the mold need to be pushed flatly against each other, which is difficult to operate. To solve this problem by changing the mold structure, the difficulty of mold processing and operation will increase accordingly, which will bring a series of problems later. After optimization by this embodiment, the optimized mold structure is as follows Figure 6 As shown, the maximum horizontal distance that the right vertical end 2 moves outward is 12.3mm, and the maximum horizontal distance that the left vertical end 1 moves outward is 4.4mm. When the left mold is closed, it is gradually pushed from the gap at a horizontal distance of 4.4mm from the intersection to the cavity, and when the right mold is closed, it is gradually pushed from the gap at a horizontal distance of 12.3mm from the intersection to the cavity, thereby reducing the difficulty of operation. The intersection is the connection point between the bent part and the adjusted inclined part, and is also the tangent point of the bend and the vertical end before adjustment.

[0078] Due to the special properties of rubber itself being soft and elastic, the rubber can be bent at will without damaging the main body structure. The rubber seal produced by the processing method of this embodiment can be easily bent back to a vertical state according to the original state for installation and use.

[0079] In this embodiment, a tilt of 3° can achieve the desired purpose. In other embodiments, tolerance calculation can be performed according to the above method to flexibly adjust the appropriate angle.
