A jig for processing explosion-proof lines on the bottom mold of a glass mold

technical field

The utility model belongs to the technical field of glass mold processing, in particular to a fixture used for processing explosion-proof patterns on the bottom mold of a glass mold.

Background technique

As known in the industry, glass products need to be transported to a designated location by a conveyor belt after being taken out of the mold for subsequent processing. Since the temperature at which the glass product is taken out from the mold is about 650°C, and the temperature of the conveyor belt in contact with the glass product is relatively low, the moment the bottom of the glass product contacts the conveyor belt, the stress concentration at the bottom of the glass product is easily caused by the existence of the temperature difference. And cracking. In order to solve this defect, the bottom of the glass bottle is often designed with some small points protruding from the bottom of the bottle to reduce the contact area between the bottom of the bottle and the conveyor belt, thereby reducing the cooling speed of the glass bottle and avoiding the bottom of the bottle from bursting. It is often called explosion-proof in the industry. pattern.

The explosion-proof pattern is usually designed into a variety of different shapes such as crescent, dot, and bar according to the structure of the bottle, customer preferences, and appreciation of appearance. Attached Figure 1 shows a schematic diagram of a crescent-shaped explosion-proof pattern. Since the accuracy of the explosion-proof pattern will directly affect the stability of the bottle placement and the performance of the bottle, the precision requirements for processing are relatively high. These blast patterns usually require glass mold bottom molds to restrict the formation. The number of explosion-proof lines is large, and the shape is complex, and the precision requirements are high. Traditional explosion-proof patterns are usually engraved by precision engraving machines, but the efficiency is low and the precision is poor, which cannot meet the needs of large quantities. For this reason, after long-term exploration, the inventor of the present invention has developed a fixture for processing the explosion-proof pattern of the glass mold bottom mold, and with the corresponding processing method, the processing efficiency of the explosion-proof pattern of the glass mold bottom mold has been greatly improved.

Contents of the invention

The task of this utility model is to provide a fixture for processing the explosion-proof pattern of the bottom mold of the glass mold in order to improve the processing efficiency of the explosion-proof pattern of the bottom mold of the glass mold.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a fixture for the explosion-proof pattern processing of the bottom mold of the glass mold, including a base, a bracket, a rotating shaft device, an indexing chuck, a chuck fixing seat, and a motor; wherein, The bracket and the rotating shaft device are arranged on the base, the indexing chuck is arranged on the chuck fixing seat, the chuck fixing seat is connected with the rotating shaft device, the chuck fixing seat can be rotated by adjusting the rotating shaft device, the motor is arranged on the chuck fixing seat and Connected with the indexing chuck, the adjusting motor can drive the indexing chuck to rotate. the

In the above technical solution, the range of the rotation angle of the chuck fixing seat relative to the plane of the fixture base can be 0-90 degrees.

The processing method used with the fixture includes the following steps:

A) Fix the bottom mold of the glass mold to be processed on the indexing chuck of the fixture, adjust the rotating shaft device of the fixture to control the rotation angle of the chuck fixing seat, and set the tool above the position where the explosion-proof pattern of the bottom mold is to be processed;

B) The tool moves to the bottom mold, controls the movement trajectory and speed of the tool, and processes an explosion-proof pattern on the bottom mold, then resets the tool and returns to the top of the explosion-proof pattern;

C) Control the motor of the bottom mold fixture to make the indexing chuck rotate together with the bottom mold, so that the next position to be processed is rotated to the bottom of the tool;

D) Repeat steps B and C until all the explosion-proof patterns on the bottom mold are processed.

The beneficial effects of the utility model are: due to the fixture used for the explosion-proof pattern processing of the bottom mold of the glass mold of the utility model, the chuck fixing seat can be rotated with the rotating shaft device as the axis, and the indexing chuck can also be mounted on the chuck fixing seat. Rotation in the plane, and the tool can move in the vertical space, so the explosion-proof pattern of the bottom mold can be processed in 3 directions by using this fixture. According to the different rotation angles of the chuck fixing seat, the shape, size and depth of the processed anti-explosion lines are all different, so that the fixture has the ability to process anti-explosion lines of various shapes. This fixture is especially suitable for high-speed machine tool control, which greatly improves the processing efficiency and processing quality of the explosion-proof pattern on the bottom mold of the glass mold.

Detailed ways

Below in conjunction with specific embodiment the utility model is described in further detail.

In this embodiment, the fixture used for processing the explosion-proof pattern of the glass mold bottom mold includes a base 1, a bracket 1, a rotating shaft device 12, an indexing chuck 2, a chuck fixing seat 3, and a motor 4; wherein, the bracket 11 and the rotating shaft device 12 Set on the base 1, the indexing chuck 2 is set on the chuck fixing seat 3, the chuck fixing seat 3 is connected with the rotating shaft device 12, the adjusting rotating shaft device 12 can make the chuck fixing seat 3 rotate, and the motor 4 is arranged on the chuck fixing seat 3. The disk holder 3 is also connected with the index chuck 2, and the adjustment motor 4 can drive the index chuck 2 to rotate. The rotation angle range of the chuck fixing seat 3 relative to the plane of the fixture base can be 0-90 degrees.

In this embodiment, the specific steps of using this fixture to make the explosion-proof pattern of the bottom mold of the glass mold are as follows:

Firstly, fix the bottom mold of the glass mold to be processed on the indexing chuck 2 of the fixture, adjust the rotating shaft device 12 of the fixture to control the rotation angle of the chuck fixing seat 3, and set the tool at the position where the explosion-proof pattern of the bottom mold is to be processed above. The shape of the tool is selected according to the shape of the explosion-proof pattern to be processed, and matches the shape of the anti-explosion pattern to be processed.

Then, the tool moves to the bottom mold, controls the movement trajectory and speed of the tool, and processes an explosion-proof pattern on the bottom mold, and then resets the tool to return to the top of the explosion-proof pattern. In this embodiment, the trajectory and speed of the tool are controlled by a machine tool, which is a precision numerical control milling machine. The machine tool manufacturer is Nanjing Xinyun CNC, and the model is V40.

Then, control the motor 4 of this fixture to make the indexing chuck 2 rotate together with the bottom mold, so that the next position to be processed is rotated to below the tool. Indexing chuck 2 and base mold rotation speed are determined according to the quantity and processing time of explosion-proof lines. Since the explosion-proof pattern processing time on the bottom mold in the present embodiment is two minutes, the number of explosion-proof patterns processed on behalf of others is 60, so the indexing chuck 2 and the bottom mold rotate 6 degrees every two seconds in the present embodiment.

Then, repeat the previous two steps until all the explosion-proof patterns on the bottom mold are processed.

The explosion-proof pattern processed by this processing method can be crescent-shaped, dot-shaped, strip-shaped or other different shapes.
