Description

Technical Field

[0001] The utility model relates to the technical field of fiber felt cutting, in particular to a fiber felt mould with cutting and edge locking functions. Background Art

[0002] Fiber felt is made of a mixture of multiple fibers and is widely used in various industries. In the interior of a car, fiber felt is pasted inside various cover panels to enhance the aesthetics and form a more advanced and unified style with the interior of the car. However, the existing fiber felt can only complete one operation during the hot pressing and cooling process of multiple layers of raw materials, and cannot complete cutting, and it is also impossible to achieve edge sealing and edge locking effects during cutting.

[0003] The existing fiber felt cutting cannot achieve the effect of locking the edges. For example, a fiber felt pressing mold cutting device disclosed in publication number CN215164032U utilizes a discharge port on a tool holder assembly that runs through both end surfaces of the tool holder from top to bottom. The discharge port corresponds to and is connected to the position of the through hole. A plurality of blades are arranged side by side and spaced apart. A plurality of blades are installed with the discharge port. A pressing assembly is located above the discharge port. The pressing assembly can be raised and lowered relative to the workbench. The pressing assembly cooperates with a plurality of blades to cut the fiber felt raw materials. This solution has the advantages of simple structure, high cutting efficiency and meeting the personalized cutting requirements. However, it still cannot achieve the effect of cutting and sealing the edges at the same time as hot pressing the fibers onto the mold plate.

[0004] Therefore, it is necessary to invent a fiber felt mold with cutting and locking function to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a fiber felt mold with cutting and edge locking functions, so as to solve the problem that the fiber felt cannot be cut and edge-sealed during the process of hot pressing molding in the technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fiber felt mold with cutting and locking function, comprising an upper cavity body and a lower cavity body, wherein the product connection surfaces of the upper cavity body and the lower cavity body match the contour of the product,

[0007] The product connection surface of the lower cavity body is provided with a knife edge, and the two sides of the knife edge are respectively the product connection surface and the outer side surface, and the angle between the product connection surface and the lower cavity body is greater than the angle between the outer side surface and the lower cavity body.

[0008] Preferably, a gas channel is provided on the upper mold cavity body, and a plurality of gas channels are provided. The gas temperature in the plurality of gas channels can heat and shape the fiber felt product body.

[0009] Preferably, positioning pieces are arranged around the upper cavity body, and the top ends of the positioning pieces are connected to buffer springs for buffering the lower cavity body, and two buffer springs are arranged.

[0010] Preferably, a pressure gauge is installed between the two buffer springs, and the pressure gauge probe extends into the upper cavity body.

[0011] Preferably, the blade and the lower cavity body are an integrated structure.

[0012] Preferably, the contact surface of the upper cavity body and the lower cavity body in the closed state is an inclined surface, and the inclination angle of the inclined surface is adapted to the inclination angle of the fiber felt product body, and the fiber felt product body is a multi-layer laminated structure.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model heat-presses the fiber felt raw materials inside by closing the upper and lower cavities, and multiple gas channels ensure that heat energy is continuously output to ensure the success rate of molding. After molding, when the fiber felt body has a fixed layered structure, the edge of the fiber felt body is cut by the knife edge in the lower cavity. Due to the special shape of the knife edge, the edge of the fiber felt body can be cut into an arc to form an edge sealing effect.

[0015] 2. After the fiber felt body is subjected to multi-layer hot-pressing molding, the utility model uses a specially shaped blade to cut its edges. The cut shape is rounded with an arc, which effectively combines the cutting and edge-sealing processes. No secondary edge-sealing is required, ensuring that the edges will not warp or come apart.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-7 The fiber felt mold with cutting and locking function shown in the figure comprises an upper cavity body 1 and a lower cavity body 3, and the product connecting surfaces of the upper cavity body 1 and the lower cavity body 3 match the contour of the product.

[0027] The product connection surface of the lower cavity body 3 is provided with a knife edge 301, and the two sides of the knife edge 301 are respectively a product connection surface 301a and an outer side surface 301b. The angle between the product connection surface 301a and the lower cavity body 3 is ( Figure 7 The angle A) is greater than the angle between the outer side surface 301b and the lower cavity body 3 ( Figure 7 Angle B).

[0028] Through closed hot pressing between the upper cavity body 1 and the lower cavity body 3, the fiber felt product body 2 is hot pressed into a multi-layer structure, and the edge 301 on the lower cavity body 3 is used to cut the edge after hot pressing. The edge sealing 201 of the cut fiber felt product body 2 has a certain curvature, which is more beautiful and not easy to warp or debond.

[0029] A gas channel 101 is provided on the upper mold cavity body 1, and there are multiple gas channels 101. The gas temperature in the multiple gas channels 101 can heat and shape the fiber felt product body 2. Positioning members 102 are provided on all sides of the upper mold cavity body 1. The top of the positioning member 102 is connected to a buffer spring 103 for buffering the lower mold cavity body 3. Two buffer springs 103 are provided, and a pressure gauge 104 is installed between the two buffer springs 103. The pressure access end of the pressure gauge 104 extends into the upper mold cavity body 1.

[0030] Multiple gas channels 101 can be used to transfer heat energy to the hot pressing molding of the entire fiber felt product body 2, and multiple positioning parts 102 and buffer springs 103 can be used to instantly relieve part of the impact force when the upper cavity body 1 and the lower cavity body 3 are closed, and the impact force is weakened while accurately aligning the edges.

[0031] The knife edge 301 and the lower cavity body 3 are an integrated structure, and the contact surface between the upper cavity body 1 and the lower cavity body 3 in the closed state is an inclined surface.

[0032] The edge of the multi-layer fiber felt product body 2 after hot pressing is cut by utilizing the special shape of the protrusion of the blade 301. The cut edge has a certain curvature, which effectively prevents warping and debonding.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual Figure 1-3 When using the utility model, the fiber felt raw material is first transported between the upper cavity body 1 and the lower cavity body 3, and is filled within the range of the lower cavity body 3. In the process of the upper cavity body 1 continuously moving downward and contacting the lower cavity body 3, hot gas is continuously filled into the gas channel 101.

[0035] When using the utility model, multiple layers of fiber felt raw materials are hot-pressed together by hot air to form a tight layered structure. After the hot pressing is completed, the knife edge 301 in the lower cavity body 3 will be cut by the formed fiber felt product body 2. By utilizing the special angle between the two side product connecting surfaces 301a and the outer surface 301b of the knife edge 301, the fiber felt product body 2 is cut and the edge is closed at the same time. The straight cut surface will not cause the cut surface to be exposed, curled or overflowed with glue. The arc-shaped knife closing operation can better avoid warping or overflow of glue at the edge.
