AI Technical Summary

Problems solved by technology

One is that there are many processes, and it is necessary to change the processing standard many times and clamp multiple times, resulting in unavoidable process errors and low product processing accuracy.
Second, the processing efficiency is low. A product uses multiple processes, various processing equipment, multiple clamping, and the labor intensity of the workers is high.
The third is that the heat treatment time is long and the cost is high, which affects the entire production cycle

Embodiment 1

[0019] A method for processing a glass mold die, the specific steps comprising:

[0020] 100), blank production: the blank can be produced from casting bars commonly used in the market;

[0021] 200), use double-station fixtures to clamp both ends of the concave-convex mold blank, process the mating surfaces of the two halves of the mold, and process the spray-welding positions that need to be spray-welded;

[0022] 300), spray welding and post-weld stress relief annealing treatment: Spray welding is carried out on the spray welding position, and then stress relief annealing is carried out, specifically, the temperature is raised from room temperature to 600°C, the heating time is 3 hours, and then kept for 3 hours, and then heated at 18°C The cooling rate per hour is reduced to 300°C, and the furnace is air-cooled;

[0023] 400), mating surface finishing;

[0024] 500), combine the mating surfaces of the two halves of the mold, use the automatic double-spindle turning and m...

Embodiment 2

[0026] A method for processing a glass mold die, the specific steps comprising:

[0027] 100), rough production: according to the product size plus machining allowance, it is obtained by ordinary gravity casting;

[0028] 200), use a double-station fixture to clamp both ends of the concave-convex mold blank, and process the mating surface where the two halves of the mold cooperate with each other;

[0029] 300), combine the mating surfaces of the two halves of the mold, use the automatic double-spindle turning and milling machining center to clamp one end, and turn and mill the other end. After the processing of one end is completed, the machine tool will automatically extend the spindle to clamp the just processed end. Then process the clamping end just now to complete the finished product processing.

Embodiment 3

[0031] A method for processing a glass mold die, the specific steps comprising:

[0032] 100), rough production: according to the product size plus machining allowance, it is obtained by ordinary gravity casting;

[0033] 200), use double-station fixtures to clamp both ends of the concave-convex mold blank, process the mating surfaces of the two halves of the mold, and process the spray-welding positions that need to be spray-welded;

[0034] 300), spray welding and post-weld stress relief annealing treatment: spray welding on the spray welding position, and then carry out stress relief annealing, specifically, the temperature is raised from room temperature to 610°C, the heating time is 3 hours, and then kept for 3 hours, then at 16°C The cooling rate per hour is reduced to 300°C, and the furnace is air-cooled;

[0035] 400), mating surface finishing;

[0036] 500), combine the mating surfaces of the two halves of the mold, use the automatic double-spindle turning and milli...

Abstract

The invention discloses a method for processing a glass mold mouth, which comprises the following steps: 100), making a blank: using a casting bar or adding a machining allowance according to the product size to obtain it through gravity casting; 200), using a double station Fixtures, respectively clamp the two ends of the concave and convex mold blank, and process the mating surface of the two halves of the mold; 300), combine the mating surfaces of the two halves of the mold, use the automatic double-spindle turning and milling machining center to clamp one end, turn and mill the other After one end, one end is processed, the machine tool automatically extends the main shaft, clamps the just processed end, and then processes the clamped end just now to complete the finished product processing. The processing method of the glass mold die of the present invention uses advanced equipment and technology to combine multiple processes, greatly reducing the number of processes, reducing the labor intensity of workers, improving product precision, and improving production efficiency.

Description

technical field [0001] The invention relates to the field of glass molds, in particular to a processing method for a glass mold die. Background technique [0002] The mouth of glass bottles and cans, for example, the mouth of beer bottles is the part with the highest quality requirements for glass packaging products, which involves the packaging speed of products after filling, packaging and sealing performance, product shelf life, etc. [0003] The glass mold die is a key part of forming the mouth of glass bottles and jars. Usually consists of two symmetrical semi-cylindrical rings. Cooperate with prototype molds, cores, mouth rings, sleeves, etc. Among all parts of the glass mold, the mouth mold has the most contact surfaces with other molds, and the structure is complex. It needs to have good assembly concentricity, verticality and other requirements with the prototype mold, forming mold, mouth ring, core and other components, and the dimensional accuracy High standard...
