Description

Technical Field

[0001] The present invention relates to the technical field of molds, and in particular to a tooling mold. Background Art

[0002] In the current market, molds are mainly divided into two types: integral molds and combination molds. Integral molds are widely used in the pressing of products that do not require high blank appearance and yield rate due to their simple structure and low cost. However, for applications with higher requirements for product quality and precision, integral molds may not meet the needs. In contrast, combination molds stand out for their ability to effectively ensure product quality. This type of mold allows for more sophisticated designs, thereby ensuring the high quality of die-casting parts. However, traditional combination molds rely on manual demolding to remove materials, a process that is not only complex and labor-intensive, but also inefficient and difficult to adapt to the fast-paced requirements of modern automated production.

[0003] Demolding is a critical step in the metal powder die casting process. However, due to the elastic aftereffect of the material (i.e. the tendency of the material to return to its original shape after the pressure is released), the edge of the blank is prone to friction with the inner wall of the mold during demolding. This can lead to a series of quality problems such as corner shedding or edge abrasions, which seriously affect the appearance and functionality of the product and increase the scrap rate. Summary of the invention

[0004] The purpose of the present invention is to provide a tooling mold to solve the technical problems in the current use of tooling molds, that is, the right-angled mold structure is prone to cause friction between the material and the surrounding of the mold during the pressing process, causing the edges and corners of the blank to fall off or be scratched, and the manual demolding process is complicated and inefficient.

[0005] The present invention provides a tooling mold, comprising: an upper mold; a lower mold; a middle mold assembly, comprising a first middle mold body and a second middle mold body arranged on the left and right; an outer mold assembly, comprising a first side mold body and a second side mold body arranged in front and back; wherein the upper mold, the lower mold, the middle mold assembly and the outer mold assembly together form a accommodating cavity for accommodating materials.

[0006] According to one embodiment of the present invention, in the intermediate mold, the horizontal cross-sections of the first middle mold body and the second middle mold body are polygonal, wherein each middle mold body includes a working surface close to the other middle mold body and an effect surface set at an angle to the working surface, and the first side mold body and the second side mold body are provided with effect corresponding surfaces matching the first middle mold body and the second middle mold body.

[0007] According to an embodiment of the present invention, the effect surface includes a first inclined surface and a second inclined surface set at an angle, and the effect corresponding surface includes a third inclined surface and a fourth inclined surface set at an angle.

[0008] According to an embodiment of the present invention, the working surface is a vertical plane, and the effect surface and the effect corresponding surface are both arranged at an angle of 40° to 50° with the working surface.

[0009] According to one embodiment of the present invention, the first side mold body and the second side mold body are connected by a spring clip.

[0010] According to one embodiment of the present invention, the spring clip is provided in plurality and is symmetrically arranged along the central axis of the upper die and the lower die.

[0011] According to one embodiment of the present invention, it further includes a bottom plate, which is arranged below the lower mold and is detachably connected to the lower mold.

[0012] According to one embodiment of the present invention, it also includes a side support plate detachably connected to the bottom plate.

[0013] According to one embodiment of the present invention, the outer mold assembly and the middle mold assembly are detachably connected.

[0014] According to one embodiment of the present invention, a pressing plate detachably connected to the upper part of the upper mold is further provided.

[0015] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0016] The present invention changes the shape of the mold assembly, changes the traditional right-angle fit to an oblique fit, transfers the lateral pressure to the axial force, and achieves a force that disperses the mold shape but does not disperse the force. By using the elastic aftereffect, the elastic effect force that hinders demoulding is converted into a power that facilitates demoulding. Specifically, during pressing, the outer mold is subjected to the lateral force, and the intermediate material is clamped by the component force on the inclined surface, overcoming the resistance of the material, and the material is pressed into shape. When the lateral pressure disappears or decreases, the intermediate mold moves outward due to the elastic aftereffect of the blank, and the outer mold is appropriately expanded, so that the material cavity becomes slightly larger, the demoulding force is reduced, the demoulding quality of the material is guaranteed, and the problems of edge loss, corner loss and abrasion caused by the friction between the blank and the mold are solved. In addition, the new mold design also improves the demoulding efficiency, reduces the need for manual intervention, makes the entire production process smoother and more efficient, and lays a solid foundation for realizing automated production.

[0026] Embodiment 1 of the present invention provides a tooling mold to transfer the lateral pressure to the axial force, so as to achieve the working force in which the mold shape is dispersed but the force is not dispersed. By utilizing the elastic aftereffect, the elastic effect force that hinders demolding is converted into the power that facilitates demolding, thereby facilitating the demolding operation and reducing manual operation to a certain extent.

[0027] See also Figure 1 , Figure 2 as well as Figure 3, the tooling mold provided by the embodiment of the present invention, the present invention provides a tooling mold, including: an upper mold 44; a lower mold 55; an intermediate mold assembly 33, including a first middle mold body 31 and a second middle mold body 32 arranged left and right; an outer mold assembly 22, including a first side mold body 21 and a second side mold body 22 arranged front and back; wherein the upper mold 44, the lower mold 55, the intermediate mold assembly 33 and the outer mold assembly 22 are surrounded by a receiving cavity for material receiving. In this embodiment, three directions of x, y and z are provided, and the x direction is the left-right direction, the y direction is the front-back direction, and the z direction is the up-down direction, wherein the upper mold 44 and the lower mold 55 are arranged at intervals in the z direction, the first middle mold body 31 and the second middle mold body 32 of the intermediate mold assembly 33 are arranged at intervals along the x direction, the first side mold body 21 and the second side mold body 22 of the outer mold assembly 22 are arranged at intervals along the y direction, and the outer mold assembly 22 is sleeved on the outer side of the lower mold 55, the first middle mold body 31 and the second middle mold body 32. Specifically, in the present embodiment, the first side mold body 21 and the second side mold body 22 are arranged on the outside of the first middle mold body 31 and the second middle mold body 32. In the present embodiment, when the upper mold 44, the lower mold 55, the middle mold assembly 33 (including the first middle mold body 31 and the second middle mold body 32 arranged on the left and right) and the outer mold assembly 22 (including the first side mold body 21 and the second side mold body 22 arranged on the front and back) are abutted, they are enclosed to form a sealed cavity for containing materials.

[0028] In this embodiment, in the middle mold, the horizontal cross-sections of the first middle mold body 31 and the second middle mold body 32 are polygonal, wherein each middle mold body includes a working surface 9 close to the other middle mold body and an effect surface set at an angle to the working surface 9, and the first side mold body 21 and the second side mold body 22 are provided with effect corresponding surfaces matching the first middle mold body 31 and the second middle mold body 32, so that the middle mold assembly 33 and the outer mold assembly 22 fit together when closed. In this embodiment, the horizontal cross-sections of the first middle mold body 31 and the second middle mold body 32 are pentagonal, and in any one of the middle mold bodies, its effect surface is far away from the working surface 9 of the other middle mold body, and the working surface 9 is close to the working surface 9 of the other middle mold body.

[0029] In this embodiment, the effect surface includes a first inclined surface 81 and a second inclined surface 82 set at an angle, and the effect corresponding surface includes a third inclined surface and a fourth inclined surface set at an angle.

[0030] In this embodiment, the working surface 9 is a vertical plane, and the effect surface and the effect corresponding surface are both arranged at an angle of 40° to 50° with the working surface 9 .

[0031] In this embodiment, the first side mold body 21 and the second side mold body 22 are connected by a spring clip 66, which ensures that the force on both sides of the mold is uniform.

[0032] In this embodiment, there are multiple spring clips 66, which are symmetrically arranged along the central axis of the upper mold 44 and the lower mold 55, ensuring that they can be separated from the middle material without affecting the elastic effect force, that is, ensuring a certain elastic effect.

[0033] In this embodiment, a bottom plate 11 is further included. The bottom plate 11 is disposed below the lower mold 55 and is detachably connected to the lower mold 55 , thereby enhancing the rigidity and stability of the entire mold structure.

[0034] In this embodiment, a side support plate 10 is further included which is detachably connected to the bottom plate 11 to limit the overall position of the mold.

[0035] In this embodiment, the outer mold assembly 22 and the middle mold assembly 33 are detachably connected and can be disassembled when used.

[0036] In this embodiment, a pressing plate 77 detachably connected to the upper mold 44 is provided to apply additional pressure during the pressing process to ensure the molding quality.

[0037] In this embodiment, the detachable connection is a bolt connection or a fixing pin connection.

[0038] The following is a detailed description of the use of the tooling mold of the present invention:

[0039] See also Figure 4 During pressing, the upper mold 44 is pressed downward, and the outer mold assembly 22 clamps the middle with the oblique component of the effect surface, overcomes the resistance of the material, and presses the material into shape; when the side pressure disappears or decreases, due to the effect of the elastic aftereffect of the blank, the middle mold assembly 33 moves outward, that is, the first middle mold body 31 and the second middle mold body 32 move away from each other in the x direction, driving the first side mold body 21 and the second side mold body 22 that are in contact with the first middle mold body 31 and the second middle mold body 32 to move away from each other in the y direction. At this time, the outer mold assembly 22 and the middle mold assembly 33 expand appropriately, making the material cavity slightly larger, reducing the demoulding force, and ensuring the demoulding quality of the material.

[0040] Example 2

[0041] Embodiment 2 of the present invention provides a tooling mold to transfer the lateral pressure to the axial force, so as to achieve the working force in which the mold shape is dispersed but the force is not dispersed. By utilizing the elastic aftereffect, the elastic effect force that hinders demolding is converted into the power that facilitates demolding, thereby facilitating the demolding operation and reducing manual operation to a certain extent.

[0042] The tooling mold provided in the embodiment of the present invention is different from that in embodiment 1 only in that the horizontal cross-sections of the first middle mold body 31 and the second middle mold body 32 can also be six-deformed, that is, an inclined surface set at an angle to the working surface 9 is provided, and the component force of the inclined surface and then the effect of the elastic back force are utilized to make the first middle mold body 31 and the second middle mold body 32 of the middle mold assembly 33 relatively far apart, and the first side mold body 21 and the second side mold body 22 of the outer membrane assembly are relatively far apart under the action of the middle mold assembly 33, so that the material cavity becomes slightly larger, the demolding force is reduced, and the demolding quality of the material is ensured.

[0043] The embodiments of the present invention have at least the following advantages:

[0044] The present invention changes the shape of the mold assembly, changes the traditional right-angle fit to an oblique fit, transmits the lateral pressure to the axial force, and achieves a force that the mold shape is dispersed but the force is not dispersed. By using the elastic aftereffect, the elastic effect force that hinders demoulding is converted into a power that facilitates demoulding. Specifically, during pressing, since the outer mold is subjected to the lateral force, the intermediate material is clamped by the component force on the inclined surface, overcoming the resistance of the material, and the material is pressed into shape. When the lateral pressure disappears or decreases, the intermediate mold moves outward due to the elastic aftereffect of the blank, and the outer mold is appropriately expanded, so that the material cavity becomes slightly larger, the demoulding force is reduced, the demoulding quality of the material is guaranteed, and the problems of edge and corner loss and abrasion caused by the friction between the blank and the mold are solved. In addition, the new mold design also improves the demoulding efficiency, reduces the need for manual intervention, makes the entire production process smoother and more efficient, and lays a solid foundation for realizing automated production.
