Description

Mould benevolence aspheric surface processing decides core tool

Technical Field

The utility model relates to a decide the core tool, especially relate to a core tool is decided in processing of mould benevolence aspheric surface.

Background

At present, the aspheric lens is usually manufactured by die casting, and in order to form the aspheric lens, the end surface of the mold core of the mold is processed into the aspheric surface. In the process of machining the mold core, the mold core is generally placed on a core positioning jig, and then the surface of the mold core is machined.

The existing core fixing jig is used for positioning the mold core through the adhesive so as to fix the mold core at the center of the core fixing jig, however, the mode of adhering the adhesive cannot ensure that the mold core is fixed at the center, so that the adjustment for a long time is needed, and the positioning is not firm.

SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme is to above-mentioned condition, and in order to solve above-mentioned problem and provide a core tool is decided in processing of mould benevolence aspheric surface, decide the core tool and include: a chassis and a core fixing sleeve; the chassis is provided with a bottom plate, a connecting rod and a cylindrical supporting table, the bottom plate, the connecting rod and the supporting table are sequentially connected from bottom to top, and the side wall of the supporting table is provided with external threads; the core fixing sleeve is provided with a sleeve ring and a pressing plate, the pressing plate is connected with the upper end of the sleeve ring, the side wall of the sleeve ring is provided with an internal thread, an external thread of the supporting table is meshed with the internal thread of the sleeve ring, the center of the pressing plate is provided with a circular through hole, and an accommodating cavity is formed between the pressing plate and the supporting table.

Further, the core sleeve is formed of a copper material.

Further, the width of the connecting rod is smaller than that of the supporting table, and the height of the external thread is smaller than that of the internal thread.

After the technical scheme is adopted, the utility model discloses an effect is: the core fixing jig with the structure can fix the mold core in the mold core processing process, is accurate in positioning, ensures that the mold core is positioned at the central position of the jig, can save labor and greatly improve efficiency.

Detailed Description

It is specifically noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture, and if the specific posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described below by way of examples:

the utility model provides a core tool is decided in processing of mould benevolence aspheric surface, it is shown with fig. 2 to combine, decides the core tool and includes: a chassis 1 and a core fixing sleeve 2; the chassis 1 is provided with a bottom plate 11, a connecting rod 12 and a cylindrical support platform 13, the bottom plate 11, the connecting rod 12 and the support platform 13 are sequentially connected from bottom to top, and the side wall of the support platform 13 is provided with an external thread 130; the core fixing sleeve 2 has a collar 21 and a pressing plate 22, the pressing plate 22 is connected with the upper end of the collar 21, the side wall of the collar 21 has an internal thread 210, the external thread 130 of the supporting table 13 is engaged with the internal thread 210 of the collar 21, the center of the pressing plate 22 has a circular through hole 220, and a receiving chamber 20 is formed between the pressing plate 22 and the supporting table 13. When the core fixing jig is used, the mold core 3 can be placed on the supporting table 13 of the chassis 1, then the outer thread 130 of the supporting table 13 is meshed with the inner thread 210 of the sleeve ring 21, the chassis 1 is connected with the core fixing sleeve 2, the bottom of the mold core 3 is located in the accommodating cavity 20, the pressing plate 22 and the supporting table 13 compress the bottom of the mold core 3, the top of the mold core 3 penetrates through the through hole 220 and extends to the upper side of the core fixing jig, and the through hole 220 can fix the mold core 3, so that the mold core 3 is ensured to be located at the center position.

Specifically, the core sleeve 2 is formed of a copper material. Compared with iron and aluminum materials, copper has better heat-conducting property, can realize quick cooling, and ensures that the molding efficiency of the mold insert 3 is higher.

Specifically, the width W1 of the connecting rod 12 is less than the width W2 (i.e., diameter) of the support table 13, and the height H1 of the external threads 130 is less than the height H2 of the internal threads 210. Through the structure, a user can adjust the meshing degree of the external threads 130 and the internal threads 210, so that the core fixing jig is suitable for mold cores 3 with different bottom thicknesses.

Therefore, the core fixing jig with the structure can fix the mold core in the mold core processing process, is accurate in positioning, ensures that the mold core is positioned at the central position of the jig, can save labor and greatly improve efficiency.
