AI Technical Summary

Technical Problem

During the hot-pressing vulcanization process of existing oil separators, the cross-section of the rubber parts becomes concave, resulting in poor sealing and oil leakage.

Method used

The design employs a groove with an upwardly concave arc-shaped cavity, combined with staggered pins and positioning posts, to ensure that the rubber part forms a raised shape during molding, thereby improving sealing performance.

Benefits of technology

With the improved tooling structure, the cross-sections of the inner and outer rubber parts are raised after molding, which improves the sealing performance of the oil distributor and avoids oil leakage.

Abstract

This application discloses a rubber-coated oil distributor fixture structure, comprising: an upper rubber-coated oil distributor fixture structure with a pressure table on the bottom surface, wherein the pressure table is provided with a pressure groove corresponding to the shape of the inner and outer rubber parts, and the pressure groove has an upwardly recessed arc-shaped cavity that connects to the pressure groove. When the inner and outer rubber parts are formed in the pressure groove and the arc-shaped cavity, the rubber material can accumulate in the upwardly recessed arc-shaped cavity, making the cross-section of the inner and outer rubber parts convex after forming. This improves the sealing performance of the oil distributor and prevents oil leakage during use. This solves the problem that when the inner and outer rubber parts are formed in a pressure groove with a flat cross-section, there is a depression in the middle, which leads to poor sealing performance and oil leakage during the use of the oil distributor.

Description

Technical Field

[0001] This utility model relates to a tooling structure for an oil separator with rubber, belonging to the technical field of hot pressing vulcanization equipment for rubber and metal parts. Background Technology

[0002] The oil separator consists of a metal shell 41, an inner rubber component 43, and an outer rubber component 44. See below. Figure 1 The inner rubber parts 43 and the outer rubber parts 44, which are connected to each other, need to be hot-pressed and vulcanized into the metal shell 41 through mold tooling.

[0003] The existing upper template 1 has a flat cross-section for the pressure groove 13, such as... Figure 6 As shown, when the inner rubber part 43 and the outer rubber part 44 are cooled in the pressure groove 13, the metal shell 41 exerts a pulling force on the inner rubber part 43 and the outer rubber part 44, resulting in a depression in the middle of the cross-section of the inner rubber part 43 and the outer rubber part 44, such as... Figure 7 As shown, the oil separator plate has poor sealing performance, leading to oil leakage. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a tooling structure for an oil separator with rubber.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a rubber-coated oil separator tooling structure, comprising: The bottom surface has an upper template with a pressing platform. The pressing platform is provided with pressing grooves corresponding to the shapes of the inner and outer rubber parts. The pressing grooves have upward-recessed arc-shaped cavities that connect to the pressing grooves.

[0007] It also includes a middle template for positioning the outer periphery of the metal shell, the middle template has a middle mold hole, and the middle mold hole has an ear plate groove corresponding to the ear plate.

[0008] The middle template and the upper template are installed by connecting them with pin A.

[0009] It also includes the lower template of the contact support template bottom surface, and the lower template has a through hole in the middle for installing positioning columns.

[0010] Pin B is installed on the outer side of the lower template, and the lower template is guided to the middle template for mold closing by pin B.

[0011] The lower template, located between pin B and the positioning post, is fitted with pin C, which is positioned and aligned with the ear plate hole.

[0012] Pin A, positioning post, pin B, and pin C are all two pins that are distributed at intervals and opposite to each other; pins A and B are staggered and not collinear when they are distributed.

[0013] The beneficial effects of this utility model are as follows: when the inner and outer rubber parts are formed in the groove and arc-shaped cavity, the rubber material can accumulate in the upwardly concave arc-shaped cavity, making the cross-section of the inner and outer rubber parts convex after forming. This helps to improve the sealing performance of the oil distributor and prevents oil leakage during use. It solves the problem that when the inner and outer rubber parts are formed in the groove with a flat cross-section, there is a depression in the middle, which leads to poor sealing performance and oil leakage during the use of the oil distributor.

Detailed Implementation

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] like Figures 1 to 5 As shown.

[0017] This application discloses a rubber-coated oil separator tooling structure, comprising: The middle template 2, which is placed on the outer periphery of the metal shell 41, has an ear plate 42 corresponding to the ear plate groove on the side of the middle mold hole 22 on the middle template 2.

[0018] It also includes an upper template 1 that is connected to the middle template 2 via a pin A11. The middle template 2 is provided with a pin hole A21 for the pin A11 to pass through. The bottom surface of the upper template 1 has a pressure table 12. The pressure table 12 is provided with a pressure groove 13 corresponding to the shape of the inner rubber part 43 and the outer rubber part 44. The pressure groove 13 has an upwardly recessed arc surface cavity 131, which is connected to the pressure groove 13. When the inner rubber part 43 and the outer rubber part 44 are formed in the pressure groove 13 and the arc surface cavity 131, the rubber material can accumulate in the upwardly recessed arc surface cavity 131, so that the cross-section of the inner rubber part 43 and the outer rubber part 44 after forming is convex 5, which is beneficial to improve the sealing performance of the oil distributor plate and prevents oil leakage during use. This solves the problem that the inner rubber part 43 and the outer rubber part 44 have a depression in the middle when forming the pressure groove 13 with a flat cross-section, which leads to poor sealing performance and oil leakage during use of the oil distributor plate.

[0019] It also includes a lower template 3 that contacts and supports the bottom surface of the middle template 2. The lower template 3 has a through hole in the middle for mounting a positioning post 31. The positioning post 31 is positioned and connected to the through hole in the middle of the metal shell 41. The lower template 3 has a through hole for mounting a pin B33 on its outer side. The lower template 3 is guided and molded with the middle template 2 by the pin B33. The lower template 3, located between the pin B33 and the positioning post 31, has a through hole for mounting a pin C32. The pin C32 is positioned and connected to the hole on the ear plate 42.

[0020] The pins A11, locating pin 31, pin B33, and pin C32 are all two pins that are distributed at intervals and opposite to each other; the pins A11 and B33 are staggered and not collinear when they are distributed.
