Abstract

The invention discloses a shoe mold core numerical control cutting machine. The shoe mold core numerical control cutting machine comprises a machine body consisting of a base and a bracket; the base is provided with a machining platform; a vertical frame is arranged on one side of the machining platform, and a numerical control console is arranged on the other side; the machining platform comprises a cross carriage, an indexing plate and a fixture; the lower part of the cross carriage is connected with the machine body, and the upper part of the cross carriage is connected with the indexing plate; the fixture comprises an electric permanent magnetic sucker fixed on the indexing plate; a lifting mechanism is arranged on a bracket; a machining main shaft parallel to the machining platform isfixed on the lifting mechanism; and a circular saw blade is mounted on the machining main shaft. The equipment can replace a five-axle machining center, a carving machine and manual cutting equipment, synthesizes the advantages of each equipment in the prior art, is low in total equipment cost, high in the machining efficiency, excellent in machined shoe mold core quantity and more comfortable inproduced shoe; and in particular, as numerical control automatic cutting is adopted, potential safety hazards are prevented, the safety of operators is improved, and the labor cost is reduced.

Description

Technical field [0001] The invention relates to the field of mechanical processing, in particular to a shoe mold core numerical control cutting machine. Background technique [0002] The core processing of the shoe mold is a key step for the quality of the finished shoes. With the enrichment of people's material life, the requirements for the comfort of shoes are getting higher and higher, especially for high heels; and more and more The shoes are designed and manufactured in accordance with the principles of human foot physiological engineering, and the soles are required to bear the weight of the wearer and ensure the quality of the shoes; it is also necessary to design the pressure uniformly according to the pressure distribution of the human feet to make the wearer more comfortable Experience, the most basic requirement is that the sole of the dragon needs to have a curvature in the Z direction, correspondingly, when making the shoe mold core, the Z direction should also have...

AI Technical Summary

Problems solved by technology

[0003] To sum up, due to the complexity of the mold core and the difficulty of the process flow, in the prior art, a five-axis machining center is used to process the shoe sole model, but due to the high investment of the five-axis machining center, the processing cost is expensive, and the cost is too high, so it is not suitable for ordinary Therefore, the equipment usually used is an engraving machine or manual cutting with a circular saw blade; but because the cutting depth of the shoe mold core is very deep, if the engraving machine is used for processing, if the depth is too deep, the milling cutter will be stressed. If it is too large, it is easy to break; in addition, the processing path of the milling cutter is long, such as a 50mm deep groove. It takes dozens of knives to complete. For the keel mold core of the sole, which has multiple keels horizontally and vertically, it takes longer and costs more, and the tool needs to be sharpened; therefore, the processing efficiency is low and the processing cost is increased.

[0004] If you use a manual circular saw blade (that is, a horizontal milling machine) to cut, you usually need to make a mark on the engraving machine first, and then manually cut one by one. It requires very skilled operators to operate, but it is also difficult to achieve the quality of the shoe core. Requirements, usually such skilled workers have a monthly salary of 10,000 yuan or more; and if ordinary operators are used for processing, it is often necessary to re-repair the mold core or directly discard the entire mold core material, because the sole The keel has a curved surface in the Z direction. It is difficult to achieve the same curvature of each groove by hand with a milling machine, which will cause uneven distribution of glue for shoemaking, waste glue, and uneven high soles will make the finished soles uncomfortable to wear; In addition, the production cycle of shoe molds is very fast. From receiving samples to mold delivery, it takes at most one week. Using a horizontal milling machine to cut grooves is relatively inefficient; this consumes a lot of manpower and material resources; High potential safety hazard, there is no safety protection in the process of processing, if the operation is improper, it is easy to cause major safety accidents

[0005] Therefore, the shoe mold core processing equipment in the prior art has the problems and deficiencies of high cost, low efficiency, poor precision, poor quality and potential safety hazards in production.
