Description

Technical Field

[0001] This application relates to the technical field of environmental protection molds, and particularly relates to a concave-convex coating structure and fixture with a friction-reducing effect. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. Lubricating oil generally consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining the basic properties of lubricating oil, and the additives can make up for and improve the deficiencies in the performance of the base oil, endowing some new properties, and are an important part of lubricating oil. Bio-based oil (vegetable oil) can be rapidly biodegradable, reducing environmental pollution, but the cost is relatively high. Generally, lubricating oil mainly using mineral base oil is used in industrial production. However, the chemical composition of mineral base oil includes high-boiling-point, high-molecular-weight hydrocarbons and non-hydrocarbon mixtures, and some of the aromatic hydrocarbons have relatively large pollution to the environment and need to be restricted in use. Therefore, all industrial enterprises in the world are now seeking measures to reduce environmental pollution. Utility Model Content

[0024] The embodiment of the present application discloses an uneven coating structure with a friction-reducing effect. Referring to Figure 1 , it includes a mold substrate 1 and a grid mesh 2. The surface of the grid mesh 2 has a number of evenly distributed mesh openings, and the range of the mesh openings is between 200 and 300. A coating 3 covering the grid mesh 2 is formed on the mold substrate 1, and the cross-section of the coating 3 is uneven.

[0025] The coating is formed by PVD deposition, and the coating is a DLC coating. The height of the coating is 0.5 - 1.5 μm, and the width of the convex coating is 60 - 150 μm.

[0027] The embodiment of the present application also discloses a fixture for processing the above-mentioned uneven coating structure with a friction-reducing effect. Referring to Figure 2, including a tail fixing block 41, a tail pressing block 42, a front adjusting block 43, a front pressing block 44 and side positioning blocks 45. The number of side positioning blocks 45 is set to two. The two side positioning blocks 45 are vertically fixed on both sides of the tail fixing block 41. A screw rod 46 is fixed at the end of the side positioning block 45 away from the tail fixing block 41. The front adjusting block 43 is movably sleeved on the screw rod 46. First locking nuts 47 are respectively threadedly connected on both sides of the front adjusting block 43 on the screw rod 46.

[0028] The tail pressing block 42 is detachably connected to the tail fixing block 41, and the front pressing block 44 is detachably fixed to the front adjusting block 43. Specifically, the tail pressing block 42 is fixed to the tail fixing block 41 by screws, and the corresponding surfaces of the tail pressing block 42 and the tail fixing block 41 are both smooth surfaces. The front pressing block 44 is fixed to the front adjusting block 43 by screws, and the corresponding surfaces of the front pressing block 44 and the front adjusting block 43 are both smooth surfaces.

[0031] The implementation principle of an uneven coating structure and fixture with a friction reduction effect in the embodiment of the present application is as follows:

[0032] This uneven coating uses the coating equipment of German PVT Ion Vacuum Technology Co., Ltd. In order to ensure good coating 3 effect, it is necessary to smoothly fit the grid mesh 2 on the surface of the mold base 1, and the distance between the grid mesh 2 and the surface of the mold base 1 should be as small as possible. Therefore, during use, first place the mold base 1 between the two side positioning blocks 45 on both sides, and fix and limit the mold base 1 through the fastening screws 49 and the positioning screws 48. After that, lay the grid mesh 2 flat on the mold base 1. The two ends of the grid mesh 2 are respectively pressed under the tail pressing block 42 and the front pressing block 44, and the position of the front adjusting block 43 is adjusted by the first locking nut 47 to tighten the grid mesh 2 and fit it on the surface of the mold base 1, so as to ensure good subsequent coating 3 effect.

[0033] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
