Description
Technical Field
The invention belongs to the field of helmet manufacturing, and particularly relates to an EPS helmet hard liner positioning and clamping tool.
Background
The helmet hard liner mainly has the functions of buffering the impact on the head and protecting the head of a wearer from being injured, and the existing helmet hard liner is usually formed by foaming expandable polystyrene foam (EPS) by a mould. In order to improve wearing comfort, the hard helmet liner can be customized and designed based on human three-dimensional head point cloud data, and for the hard helmet liner which is customized and designed, if the hard helmet liner is molded by foaming through a mold, the production period is long, the mold cost is high, the product cost is high, and the hard helmet liner cannot be popularized and applied, so that an EPS blank piece is optimally machined by numerical control milling according to the shape, but the EPS material is relatively soft, the profile of the hard helmet liner is approximately spherical, and the hard helmet liner is not easy to position and clamp.
Disclosure of Invention
The invention aims to provide a positioning and clamping tool for an EPS helmet hard liner, which meets the milling processing requirement of a personalized customized helmet hard liner, has good positioning and pressing effects, does not damage parts, and is convenient to disassemble.
The technical scheme adopted by the invention is as follows:
the EPS helmet hard lining positioning and clamping tool comprises a female die, wherein the inner molded surface of the female die is consistent with the outer molded surface of a helmet hard lining blank, the edge of the inner molded surface is flush with the edge of the helmet hard lining blank, an air exhaust channel is arranged on the female die, and one end of the air exhaust channel is arranged at the lower part of the inner molded surface, and the other end of the air exhaust channel is externally connected to a vacuum generator.
Furthermore, a circle of groove is arranged near the upper edge of the inner profile along the circumferential direction, and a sealing ring is embedded in the groove.
Further, the sealing ring adopts a hollow sealing pipe.
Furthermore, one end of the air exhaust channel, which is far away from the inner molded surface, is arranged on the side surface of the female die and is provided with an air nozzle, and the vacuum generator is connected with the air nozzle through an air pipe.
Furthermore, the side surface of the female die is designed into a reference surface, the upper end surface is designed with a reference hole, and the reference surface and the reference hole are used as manufacturing references and used for alignment in numerical control machining.
The invention has the beneficial effects that:
this frock adopts the vacuum adsorption power to compress tightly the helmet hard liner that the material is softer and have spherical outer profile, adapts to individualized customization helmet hard liner milling process demand, and location and compress tightly effectually, and do not harm the part, and under the condition that the pipeline is lost air, the vacuum adsorption power that helmet hard liner received disappears, can take out from the die easily, and it is convenient to dismantle.

FIG. 2 is a cross-sectional view of a female mold in an embodiment of the invention.
In the figure: 1-a female die; 2-sealing ring; 3-air tap; 4-trachea; 5-a vacuum generator; 6-a reference plane; 7-reference hole.
Detailed Description
The invention is further illustrated by the following figures and examples.
As shown in fig. 1 and 2, the EPS helmet hard liner positioning and clamping tool comprises a female die 1, wherein the inner profile of the female die 1 is consistent with the outer profile of a helmet hard liner blank, the edge of the inner profile is flush with the edge of the helmet hard liner blank, the female die 1 is provided with an air exhaust channel, one end of the air exhaust channel is arranged at the lower part of the inner profile, and the other end of the air exhaust channel is externally connected to a vacuum generator 5. This frock adopts the vacuum adsorption power to compress tightly the helmet hard liner that the material is softer and have spherical outer profile, adapts to individualized customization helmet hard liner milling process demand, and location and compress tightly effectually, and do not harm the part, and under the condition that the pipeline is lost air, the vacuum adsorption power that helmet hard liner received disappears, can take out from die 1 easily, and it is convenient to dismantle.
As shown in fig. 1 and 2, in this embodiment, a circle of groove is circumferentially arranged near the upper edge of the inner profile, a sealing ring 2 is embedded in the groove, and the sealing ring 2 can form a matching closed space to improve the adsorption effect. The sealing ring 2 is preferably a hollow sealing tube with good elasticity.
As shown in fig. 1 and 2, in this embodiment, one end of the air suction passage away from the inner surface of the passage is opened on the side of the female die 1 and is provided with an air nozzle 3, and a vacuum generator 5 is connected with the air nozzle 3 through an air pipe 4.
As shown in fig. 1, in the present embodiment, the side surface of the die 1 is designed as a reference surface 6, the upper end surface is designed with a reference hole 7, and the reference surface 6 and the reference hole 7 are used as manufacturing references for alignment during numerical control machining, so as to facilitate subsequent machining.
It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
