Description
Technical Field
[0001] This utility model relates to the field of mold coating applications, specifically an auxiliary structure for coating the end face of a columnar mold. Background Technology
[0002] Coating is a process that uses specific techniques to attach a thin, hard film to the surface of an object. The core purpose is to protect the surface of the object and improve its performance. During the coating process, coating trays, back plates, or auxiliary structures are needed to ensure the object is positioned stably and to allow the film to adhere evenly and fully to the target surface.
[0003] During aspherical molding, the high pressure and high temperature environment requires the mold surface to be coated with a thin and hard film layer. Due to the mold structure requirements, some molds are designed as cylinders with one end being an aspherical curved surface and the other end being a flat surface for bearing the force. Generally, the mold is designed with a stepped structure, and holes are inserted for limiting during coating. The mold plane and the back plate used during coating are fixed by the coating plate and the back plate, so that the mold plane is tightly attached to the back plate, thus completing the aspherical surface facing outward and more fully completing the coating.
[0004] When applying end-face coating to a cylindrical mold without steps, and when the mold plane needs to be in close contact with the back plate and the non-spherical curved surface needs to be fully exposed to achieve the same coating effect as a stepped mold, the mold without steps cannot be directly limited by the existing coating plate. Therefore, an auxiliary structure for end-face coating of cylindrical molds is proposed to address the above problem. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A columnar mold end face coating auxiliary structure of this utility model includes a coating disk body; multiple sets of coating disk placement holes are opened at the top of the coating disk body; the coating disk placement holes are evenly arranged at the top of the coating disk body; a fixing seat body is provided in the middle of the coating disk placement hole; a fixing seat outer step is provided at the bottom of the fixing seat body; the outer diameter of the fixing seat outer step is larger than the inner diameter of the coating disk placement hole; multiple sets of fixing seat claws are fixedly connected to the top of the fixing seat body; a fixing seat circular hole is opened in the middle of the fixing seat body; a cylindrical mold aspherical surface is provided in the middle of the fixing seat circular hole; the top of the fixing seat claws can limit the edge of the cylindrical mold aspherical surface; by the fixing seat body engaging with the coating disk placement hole through the fixing seat outer step, it achieves stable fixation on the coating disk body, reducing the offset of the fixing seat body. On the other hand, the clamping jaws at the top of the fixing seat body limit and clamp the edge of the cylindrical mold aspherical surface inside the circular hole of the fixing seat, which can reduce the dropping or displacement of the cylindrical mold aspherical surface, ensuring that the end face of the cylindrical mold aspherical surface to be coated is always in the preset position, reducing coating defects caused by the shaking of the cylindrical mold aspherical surface. The top of the coating tray body has multiple sets of coating tray placement holes evenly opened, and each set of coating tray placement holes can be equipped with the fixing seat body and place the cylindrical mold aspherical surface, so that the coating tray body can perform coating operations on multiple sets of cylindrical mold aspherical surfaces at the same time, improving coating output and adapting to the needs of batch production. The limiting of the cylindrical mold aspherical surface by the clamping jaws only acts on the ineffective area of the edge of the cylindrical mold aspherical surface, and will not block the end face of the cylindrical mold aspherical surface to be coated, ensuring that the end face of the cylindrical mold aspherical surface to be coated is fully coated, so that the film layer is evenly adhered, meeting the coating accuracy requirements of the aspherical mold.
[0007] Preferably, the clamping claws of the fixing seat are symmetrically arranged at the top of the fixing seat body; the symmetrically arranged clamping claws of the fixing seat form a uniform clamping force on the edge of the aspherical surface of the cylindrical mold, which can limit the position from the symmetrical direction around the aspherical surface of the cylindrical mold, reduce the displacement or tilting of the aspherical surface of the cylindrical mold in the circular hole of the fixing seat due to uneven force, ensure that the end face of the aspherical surface of the cylindrical mold to be coated always remains horizontal and in the preset coating position, and further reduce the problem of uneven film thickness caused by the posture deviation of the aspherical surface of the cylindrical mold.
[0008] The advantages of this utility model are: 1. The auxiliary structure for coating the end face of a cylindrical mold described in this utility model achieves stable fixation on the coating tray body by means of the matching engagement between the outer step of the fixing seat body and the placement hole of the coating tray body, reducing the offset of the fixing seat body body. On the other hand, the fixing seat claw at the top of the fixing seat body forms a limiting clamping on the non-spherical edge of the cylindrical mold inside the circular hole of the fixing seat, which can reduce the non-spherical surface of the cylindrical mold from falling or shifting, ensuring that the non-spherical end face of the cylindrical mold to be coated is always in the preset position, reducing coating defects caused by the shaking of the non-spherical surface of the cylindrical mold, and the coating tray. Multiple sets of coating disc placement holes are evenly opened on the top of the main body. Each set of coating disc placement holes can be fitted with a fixing base body and place the cylindrical mold aspherical surface. This allows the coating disc body to perform coating operations on multiple sets of cylindrical mold aspherical surfaces simultaneously, increasing coating output and adapting to batch production needs. The fixing base jaws limit the cylindrical mold aspherical surface only in the ineffective area of the cylindrical mold aspherical surface edge, and will not block the end face of the cylindrical mold aspherical surface to be coated. This ensures that the end face of the cylindrical mold aspherical surface to be coated is fully coated, so that the film layer is evenly adhered and meets the coating precision requirements of the aspherical mold.
[0009] 2. The auxiliary structure for coating the end face of a cylindrical mold described in this utility model forms a uniform clamping force on the edge of the aspherical surface of the cylindrical mold through symmetrically arranged fixed seat claws. It can limit the position from the symmetrical direction around the aspherical surface of the cylindrical mold, reduce the displacement or tilting of the aspherical surface of the cylindrical mold due to uneven force in the circular hole of the fixed seat, and ensure that the end face of the aspherical surface of the cylindrical mold to be coated always remains horizontal and in the preset coating position, further reducing the problem of uneven film thickness caused by the posture deviation of the aspherical surface of the cylindrical mold.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0013] Specific implementation examples are given below.
[0014] like Figures 1 to 2As shown in the embodiment of this utility model, a coating auxiliary structure for the end face of a columnar mold includes a coating disk body 1; the top of the coating disk body 1 has multiple sets of coating disk placement holes 11; the coating disk placement holes 11 are evenly distributed at the top of the coating disk body 1; a fixing seat body 12 is provided in the middle of the coating disk placement hole 11; the bottom end of the fixing seat body 12 is provided with a fixing seat outer step 13; the outer diameter of the fixing seat outer step 13 is larger than the inner diameter of the coating disk placement hole 11; multiple sets of fixing seat claws 14 are fixedly connected to the top of the fixing seat body 12; the fixing... The base body 12 has a fixed seat circular hole 15 in the middle; a cylindrical mold aspherical surface 16 is provided in the middle of the fixed seat circular hole 15; the top of the fixed seat claw 14 can limit the edge of the cylindrical mold aspherical surface 16; during operation, the fixed seat body 12 is aligned with the pre-set coating disk placement hole 11 on the coating disk body 1, and the fixed seat outer step 13 at the bottom of the fixed seat body 12 is matched and engaged with the diameter of the coating disk placement hole 11, so that the fixed seat body 12 is stably embedded in the coating disk placement hole 11 of the coating disk body 1, ensuring that the fixed seat body 12 will not be damaged during subsequent operations. After offsetting or shaking, the cylindrical mold aspherical surface 16 to be coated is then placed into the fixed seat circular hole 15 in the middle of the fixed seat body 12. At this time, multiple sets of fixed seat claws 14 fixed to the top of the fixed seat body 12 will form a limiting clamp on the edge of the cylindrical mold aspherical surface 16, confining the cylindrical mold aspherical surface 16 within the fixed seat circular hole 15, ensuring that the end face of the cylindrical mold aspherical surface 16 to be coated is fully exposed. After confirming that the cylindrical mold aspherical surface 16 is stably limited by the fixed seat claws 14 and that the fixed seat body 12 is firmly assembled with the coating disc body 1, the coating equipment is started to coat the cylindrical mold aspherical surface 16. The outer end face of the cylindrical mold aspherical surface 16 is coated. After the coating of the cylindrical mold aspherical surface 16 is completed, the clamping jaws 14 of the fixing seat are released from the limiting position of the cylindrical mold aspherical surface 16. The cylindrical mold aspherical surface 16 is taken out from the circular hole 15 of the fixing seat. Then, the fixing seat body 12 is removed from the coating plate body 1 through the cooperation of the fixing seat outer step 13 and the coating plate placement hole 11, thus completing the coating process. The multiple sets of coating plate placement holes 11 on the top of the coating plate body 1 can hold multiple sets of fixing seat bodies 12, so that the coating plate body 1 can coat multiple sets of cylindrical mold aspherical surfaces 16 at one time.The fixing seat body 12 achieves stable fixation on the coating tray body 1 by engaging with the outer step 13 of the fixing seat and the placement hole 11 of the coating tray, reducing the offset of the fixing seat body 12. On the other hand, the fixing seat claw 14 at the top of the fixing seat body 12 forms a limiting clamp on the edge of the cylindrical mold aspherical surface 16 in the circular hole 15 of the fixing seat, which can reduce the falling or displacement of the cylindrical mold aspherical surface 16, ensuring that the end face of the cylindrical mold aspherical surface 16 to be coated is always in the preset position, reducing coating defects caused by the shaking of the cylindrical mold aspherical surface 16. Multiple sets of coating trays are evenly opened on the top of the coating tray body 1. The coating plate placement holes 11 allow for the mounting of a fixed base body 12 and the placement of a cylindrical mold aspherical surface 16. This enables the coating plate body 1 to simultaneously perform coating operations on multiple sets of cylindrical mold aspherical surfaces 16, increasing coating output and adapting to batch production needs. The fixed base grippers 14 limit the movement of the cylindrical mold aspherical surface 16, acting only on the ineffective area of the edge of the cylindrical mold aspherical surface 16. This does not obstruct the coating end face of the cylindrical mold aspherical surface 16, ensuring sufficient coating on the coating end face and uniform film adhesion, meeting the coating precision requirements of the aspherical mold.
[0015] like Figure 2 As shown, the fixed base grippers 14 are symmetrically arranged at the top of the fixed base body 12. During operation, the fixed base grippers 14 are symmetrically arranged in pairs at the top of the fixed base body 12, which allows the fixed base grippers 14 to form a symmetrical limit around the edge of the cylindrical mold aspherical surface 16, thus stabilizing the limit of the cylindrical mold aspherical surface 16. The symmetrically arranged fixed base grippers 14 form a uniform clamping force on the edge of the cylindrical mold aspherical surface 16, which can limit the cylindrical mold aspherical surface 16 from a symmetrical direction around the edge, reducing the displacement or tilt of the cylindrical mold aspherical surface 16 in the fixed base circular hole 15 due to uneven force. This ensures that the end face of the cylindrical mold aspherical surface 16 to be coated always remains horizontal and in the preset coating position, further reducing problems such as uneven film thickness caused by the posture deviation of the cylindrical mold aspherical surface 16.
[0016] Working principle: Align the fixing base body 12 with the pre-set coating tray placement hole 11 on the coating tray body 1. The fixing base body 12 is stably embedded in the coating tray placement hole 11 by the matching and engagement of the fixing base outer step 13 at the bottom end of the fixing base body 12 with the diameter of the coating tray placement hole 11, ensuring that the fixing base body 12 will not shift or shake during subsequent operations. Then, place the cylindrical mold aspherical surface 16 to be coated into the fixing base circular hole 15 opened in the middle of the fixing base body 12. At this time, the multiple sets of fixing base claws 14 fixed to the top end of the fixing base body 12 will form a limiting clamp on the edge of the cylindrical mold aspherical surface 16, limiting the cylindrical mold aspherical surface 16 within the fixing base circular hole 15, ensuring that the end face of the cylindrical mold aspherical surface 16 to be coated is fully exposed. After confirming that the cylindrical mold aspherical surface 16 is stably limited by the fixing base claws 14 and the fixing base body 12 is aligned with the coating tray placement hole 11, the fixing base body 12 is stably embedded in the coating tray placement hole 11 on the coating tray body 12. After the coating plate body 1 is securely assembled, the coating equipment is started to coat the outer end face of the cylindrical mold aspherical surface 16. After the coating of the cylindrical mold aspherical surface 16 is completed, the clamping jaws 14 of the fixing seat are released from the limiting position of the cylindrical mold aspherical surface 16, and the cylindrical mold aspherical surface 16 is removed from the circular hole 15 of the fixing seat. Then, the fixing seat body 12 is removed from the coating plate body 1 through the cooperation of the fixing seat outer step 13 and the coating plate placement hole 11, thus completing the coating process. The multiple sets of coating plate placement holes 11 at the top of the coating plate body 1 can accommodate multiple sets of fixing seat bodies 12, so that the coating plate body 1 can coat multiple sets of cylindrical mold aspherical surfaces 16 at one time. The clamping jaws 14 are symmetrically arranged in pairs at the top of the fixing seat body 12, so that when the clamping jaws 14 limit the edge of the cylindrical mold aspherical surface 16, a symmetrical limiting position is formed around the perimeter, which stabilizes the limiting position of the cylindrical mold aspherical surface 16.
[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
