Embodiment 1

[0033] A fabric profiling mold, comprising an inner rigid mandrel 1, an outer flexible cushion 2, a middle variable rigid cushion 3, a stable chassis 5,

[0034] The bottom of described inner layer rigid mandrel 1 is fixedly connected with stable chassis 5, and described middle layer becomes rigid pad 3 is arranged between inner rigid mandrel 1 and outer flexible pad 2. After the mold is formed, its shape is exactly the same as that of the prefabricated body, and the error is not more than 1mm.

[0035] Further, the shape of the mold includes but not limited to a regular body of revolution, a body of revolution with variable cross-section, and a solid body with variable cross-section.

[0036] Further, the material of inner layer rigid mandrel 1 is selected to have certain rigidity, not easily deformed, the material that is easy to machine, including but not limited to iron, aluminum, copper. Its shape is contracted according to the shape of the prefabricated body, and the su...

Embodiment 2

[0052] Such as Figure 5 As shown, a profiling mold for acupuncture preforms includes 1-inner rigid mandrel, 2-outer flexible cushion, 3-middle variable rigid cushion, 5-stable chassis, 7-position calibration device, When the inner rigid mandrel 1 is formed by splicing multiple pieces, the inner rigid mandrel 1 includes a central axis mounting hole, a mold positioning hole 10, and an electrical component mounting hole. Through the central axis mounting hole, it is ensured that the mold can be fixed on the On the central axis; the positioning pin and the mold positioning hole 10 are used to ensure the accurate position of the mold; the installation holes of electrical components are convenient for the control components to be embedded in the fabric. The material of the outer flexible cushion layer 2 is organic material, spliced ​​in pieces, and the single cushion layer is integrally formed.

[0053] Among them, the middle variable rigid cushion layer 3 and the outer flexible c...

Embodiment 3

[0057] Such as Figure 6-8 As shown, this embodiment is a kind of three kinds of middle layer variable rigid cushion of acupuncture preform profiling mold, including 1-triangular variable rigid cushion, 2-square variable rigid cushion, 3-honeycomb variable rigid cushion layer.

[0058] Among them, three different rigid materials are filled in the triangular variable-rigidity cushion, and each filling unit is connected by side wall hook and loop to ensure the connection rigidity and can be disassembled at any time. The side wall of the filling unit is made of soft materials, such as EVA, etc. Made of high-quality materials, the shape of the cushion has good plasticity.

[0059] Among them, three different rigid materials are filled in the square variable-rigidity cushion respectively, and pins are used to connect each filling unit to ensure the connection rigidity and can be disassembled at any time. The side walls of the filling unit are made of hard materials, such as plexig...

Abstract

The invention discloses a fabric profiling mold which comprises an inner-layer rigid core mold (1), an outer-layer flexible cushion layer (2), a middle-layer variable-rigidity cushion layer (3) and a stable base plate (5), the bottom of the inner-layer rigid core mold (1) is fixedly connected with the stable base plate (5), and the middle-layer variable-rigidity cushion layer (3) is arranged between the inner-layer rigid core mold (1) and the outer-layer flexible cushion layer (2). The middle layer variable-rigidity cushion layer adopts a layered design, the rigidity is gradually improved from inside to outside, the rigidity is continuously adjustable within a certain range by adjusting the proportion of middle layer filler, and a heating resistance wire is arranged in the middle layer variable-rigidity cushion layer so that the mold is heated in the preparation process, and it is guaranteed that the fabric forming requirement is met. The mold is high in profiling precision, high in reusability, low in cost and beneficial to improving the working efficiency.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a fabric profiling mold. Background technique [0002] The fabric profiling mold is a mold used in the forming process of needle-punched fabrics with shape profiling requirements. It is mainly used in the forming process of needle-punched fabrics with certain three-dimensional profiles and profiling requirements. By laying the raw material on the surface of the mold and repeatedly needling it with special shaped needles, the raw material is consolidated according to the shape of the mold, and finally a profiling needle-punched fabric is formed. The profiling accuracy of the prefabricated body prepared by the fabric profiling mold in the prior art is not high, and the reusability is low simultaneously, and the cost is high, which is not conducive to improving work efficiency. Contents of the invention [0003] The object of the present invention is to provide a fabric profiling ...
