Description

Technical Field

[0001] The present application relates to the technical field of die-cast aluminum alloy machining, and in particular to a cake mold structure. Background Art

[0002] In recent years, new energy vehicles have promoted the accelerated development of integrated die-casting technology. Integrated die-casting is conducive to reducing the number of parts, speeding up production efficiency, reducing quality, and thus reducing costs. Reducing the production rhythm of integrated die-casting parts is a key link in improving production efficiency, and it is also a difficult problem that major die-casting companies need to explore. Among them, an important factor affecting the production rhythm of integrated die-casting parts is the cooling and solidification time of integrated die-casting parts, and the die-casting cake is the thickest part of the production rhythm of integrated die-casting parts. Especially for large-scale integrated body die-casting structural parts, the amount of aluminum alloy poured at one time is large, and the heat release is large. If the cooling time is not properly controlled during the production process, it is easy to have problems such as difficulty in demolding the die-casting cake, breaking the die-casting cake, and exploding the cake, thereby affecting continuous production.

[0003] See also Figure 1 and Figure 2 The conventional die-casting mold forms a die-casting cake 91 by combining the diverter cone 101 and the sprue sleeve 102 thereon and contacting the aluminum liquid by injection. During the injection process, the diverter cone 101 or the sprue sleeve 102 is continuously impacted by the high-temperature aluminum liquid, so it is necessary to open a straight cooling hole inside the diverter cone 101 and the sprue sleeve 102. However, due to the limitation of the processing technology, the diverter cone cooling system 103 or the sprue sleeve cooling system 104 in the conventional die-casting mold can only realize a simple cylindrical cooling water pool, and the distance from the aluminum liquid contact surface to the cooling water pool hole is not equidistant, so that the heat conduction cooling rate is not the same, and it is difficult to achieve uniform cooling, which leads to the die-casting cake 91 and the transition fillet 93 of the die-casting straight runner 92 being prone to bursting, thereby affecting the production rhythm of the die-casting cake 91. Utility Model Content

[0004] The purpose of the present application is to provide a die-casting mold structure to solve the problem that the distance between the surface of the die-casting cake die-casted by the traditional die-casting mold and the cooling water pool hole of the die-casting mold is not equidistant, thereby making the heat conduction cooling rate different, making it difficult to achieve uniform cooling, and thus affecting the production rhythm of the die-casting cake.

[0005] In order to achieve the above purpose, the technical solution adopted in this application is as follows:

[0006] A biscuit mold structure comprises: an integral pressure chamber; a movable mold insert, which is arranged on one side of the integral pressure chamber and is used to combine with the integral pressure chamber to form a biscuit cavity, and the biscuit cavity is used to die-cast biscuits; the biscuit cavity has a first plane close to the integral pressure chamber and a second plane close to the movable mold insert, and the first plane and the second plane are arranged in parallel and opposite to each other; a first cooling layer arranged in parallel with the first plane is provided on the side of the integral pressure chamber away from the biscuit cavity, and a second cooling layer arranged in parallel with the second plane is provided on the side of the movable mold insert away from the biscuit cavity, wherein the first cooling layer and the second cooling layer are both used for circulating cooling liquid; the distance from the first cooling surface of the first cooling layer to the first plane is the same as the distance from the second cooling surface of the second cooling layer to the second plane.

[0007] According to the above technical means, by setting the surface of the cake cavity close to the overall pressure chamber and the movable mold insert as the first plane and the second plane respectively, the first surface and the second surface of the die-cast cake are also planes, and then the distance between the first cooling surface of the first cooling layer close to the first plane and parallel to the first plane and the first plane is set to be the same as the distance between the second cooling surface of the second cooling layer close to the second plane and parallel to the second plane and the second plane, thereby ensuring that the cooling effect of the first cooling layer on the first plane is consistent with the cooling effect of the second cooling layer on the second plane, and uniform cooling is achieved, which also ensures that the cooling effect of the first cooling layer on the first surface of the cake is consistent with the cooling effect of the second cooling layer on the second surface of the cake, and uniform cooling is achieved, thereby reducing the production rhythm of the cake.

[0008] Furthermore, the cake cavity includes a cake groove, which is arranged on a side of the overall pressure chamber close to the movable mold insert, the first plane is a side of the overall pressure chamber close to the cake groove, and the second plane is a side of the movable mold insert close to the cake groove.

[0009] According to the above technical means, the present application only opens a cake groove on one side of the overall pressure chamber, and uses the first plane as the side of the movable mold insert close to the cake groove. Compared with the solution of opening grooves on both the overall pressure chamber and the movable mold insert, and forming a cake cavity when the respective grooves are combined, this embodiment simplifies the design steps of the cake cavity of the cake mold structure, and the structure is simple and easy to design.

[0010] Furthermore, the distance between the first cooling surface of the first cooling layer and the first plane is 25-35 mm.

[0011] According to the above technical means, the cooling effect of the first cooling layer and the second cooling layer on the material cake and the entire pressure chamber and the movable mold insert can be guaranteed without affecting the production rhythm of the material cake.

[0012] Furthermore, the first cooling layer includes a first cooling water channel and a second cooling water channel arranged in parallel, and the first cooling water channel and the second cooling water channel are independently controlled.

[0013] According to the above technical means, more power can be provided to the first cooling water channel and the second cooling water channel, which can improve the cooling effect of the first cooling water channel and the second cooling water channel respectively, thereby improving the cooling effect of the first cooling layer on the material cake and the overall pressure chamber, and improving the service life of the overall pressure chamber.

[0014] Furthermore, the overall pressure chamber is a cylinder, and the first cooling water channel and the second cooling water channel are both annular water channels.

[0015] According to the above technical means, since the overall pressure chamber is set as a cylinder, the first cooling water channel and the second cooling water channel are both set as annular water channels, which can improve the cooling effect of the first cooling water channel and the second cooling water channel in the overall pressure chamber, thereby improving the cooling effect of the first cooling layer.

[0016] Furthermore, the second cooling layer includes a third cooling water channel and a fourth cooling water channel which are arranged in parallel, and the third cooling water channel and the fourth cooling water channel are independently controlled.

[0017] According to the above technical means, the third cooling water channel and the fourth cooling water channel can be provided with more power, which can improve the cooling effect of the third cooling water channel and the fourth cooling water channel respectively, thereby improving the cooling effect of the second cooling layer on the material cake and the movable mold insert, and increasing the service life of the movable mold insert.

[0018] Furthermore, the cake trough is a cylindrical trough.

[0019] According to the above technical means, by setting the cake trough as a cylindrical trough, the structure is simple and easy to design.

[0020] Furthermore, the integral pressure chamber is provided with a sprue groove on one side of the material cake groove, and the sprue groove is recessed toward a side away from the movable mold insert.

[0021] According to the above technical means, it can be foreseen that under the uniform cooling of the first cooling layer and the second cooling layer, the die-casting cake is not likely to burst at the excessively rounded corner between it and the sprue.

[0022] Beneficial effects of this application:

[0023] The present application sets the surface of the cake cavity close to the overall pressure chamber and the movable mold insert as the first plane and the second plane respectively, so that the first surface and the second surface of the die-cast cake are also planes, and then the distance between the first cooling surface of the first cooling layer close to and parallel to the first plane and the first plane is set to be the same as the distance between the second cooling surface of the second cooling layer close to and parallel to the second plane and the second plane, thereby ensuring that the cooling effect of the first cooling layer on the first plane is consistent with the cooling effect of the second cooling layer on the second plane, and cooling is uniform, which also ensures that the cooling effect of the first cooling layer on the first surface of the cake is consistent with the cooling effect of the second cooling layer on the second surface of the cake, and cooling is uniform, thereby reducing the production rhythm of the cake.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0031] See also Figure 3 and Figure 4 The present embodiment proposes a material cake mold structure, including an integral pressure chamber 1 and a movable mold insert 2, wherein the movable mold insert 2 is arranged on one side of the integral pressure chamber 1 and is used to be combined with the integral pressure chamber 1 to form a material cake cavity for die-casting a material cake 4, wherein the material cake cavity has a first plane close to the integral pressure chamber 1 and a second plane close to the movable mold insert 2, wherein the first plane and the second plane are arranged parallel to and opposite to each other, wherein the first surface of the material cake 4 corresponds to the first plane, and the second surface of the material cake 4 corresponds to the second plane, a first cooling layer 5 arranged parallel to the first plane is provided on the side of the integral pressure chamber 1 away from the material cake cavity, and a movable mold insert 2 is provided on the side away from the material cake cavity There is a second cooling layer 6 arranged parallel to the second plane, the first cooling layer 5 and the second cooling layer 6 are used for circulating cooling liquid, the distance between the first cooling surface of the first cooling layer 5 and the first plane is the same as the distance between the second cooling surface of the second cooling layer 6 and the second plane, wherein the first cooling surface is arranged on the side of the first cooling layer 5 closest to the material cake cavity, and the second cooling surface is arranged on the side of the second cooling layer 6 closest to the material cake cavity. It is worth noting that in this embodiment, the cooling capacity of the first cooling layer 5 to the first plane (the first side of the material cake 4) is the same as the cooling capacity of the second cooling layer 6 to the second plane (the second side of the material cake 4).

[0032] That is to say, the cake cavity is formed by the die-casting liquid (such as aluminum liquid) used for die-casting to form the cake 4. In order to ensure that the formed cake 4 is cooled evenly, this embodiment sets the surfaces of the cake cavity close to the overall pressure chamber 1 and the movable mold insert 2 as the first plane and the second plane respectively, so that the first surface 41 and the second surface 42 of the die-cast cake 4 are also planes, and then the distance between the first cooling surface of the first cooling layer 5 close to the first plane and parallel to the first plane and the first plane is set to be the same as the distance between the second cooling surface of the second cooling layer 6 close to the second plane and parallel to the second plane and the second plane, thereby ensuring that the cooling effect of the first cooling layer 5 on the first plane is consistent with the cooling effect of the second cooling layer 6 on the second plane, and cooling is uniform, which also ensures that the cooling effect of the first cooling layer 5 on the first surface 41 of the cake 4 is consistent with the cooling effect of the second cooling layer 6 on the second surface 42 of the cake 4, and cooling is uniform, thereby reducing the production rhythm of the cake 4.

[0033] See also Figure 3In this embodiment, the cake cavity includes a cake groove 3, and the cake groove 3 can be arranged on the side of the overall pressure chamber 1 close to the movable mold insert 2. At this time, the first plane is the side of the overall pressure chamber 1 close to the cake groove 3, and the second plane is the side of the movable mold insert 2 close to the cake groove 3. Of course, the cake groove 3 can also be arranged on the side of the movable mold insert 2 close to the overall pressure chamber 1. In this embodiment, the cake groove 3 is preferably arranged on the side of the overall pressure chamber 1 close to the movable mold insert 2. In this embodiment, the cake groove 3 is only opened on one side of the overall pressure chamber 1, and the first plane is used as the side of the movable mold insert 2 close to the cake groove 3. Compared with the scheme of opening grooves on both the overall pressure chamber 1 and the movable mold insert 2, and forming a cake cavity when the respective grooves are combined, this embodiment simplifies the design steps of the cake cavity of the cake mold structure, and the structure is simple and easy to design.

[0034] See also Figure 3 In this embodiment, the overall pressure chamber 1 can be a cylinder.

[0035] See also Figure 3 In this embodiment, the movable mold insert 2 can be a rectangular block.

[0036] See also Figure 3 and Figure 4 In this embodiment, the cake trough 3 can be a cylindrical trough. In this embodiment, the cake trough 3 is set as a cylindrical trough, so the structure is simple and easy to design.

[0037] In this embodiment, the distance between the first cooling surface of the first cooling layer 5 and the first plane can be 25-35mm, and correspondingly, the distance between the second cooling surface of the second cooling layer 6 and the second plane can be 25-35mm. It can be understood that if the distance between the first cooling surface of the first cooling layer 5 and the first plane is 25mm, then the distance between the second cooling surface of the second cooling layer 6 and the second plane is also 25mm; if the distance between the first cooling surface of the first cooling layer 5 and the first plane is 35mm, then the distance between the second cooling surface of the second cooling layer 6 and the second plane is also 35mm. By setting the distance between the first cooling surface of the first cooling layer 5 and the first plane at 25-35mm, this embodiment can ensure the cooling effect of the first cooling layer 5 and the second cooling layer 6 on the material cake 4 and the overall pressure chamber 1 and the movable mold insert 2, and at the same time does not affect the production rhythm of the material cake 4.

[0038] See also Figure 3In the present embodiment, the coolant may be water, wherein the first cooling layer 5 comprises a first cooling water channel 51 and a second cooling water channel 52 arranged in parallel, the first cooling surface is arranged on a surface of the first cooling water channel 51 away from the second cooling water channel 52, the first cooling water channel 51 and the second cooling water channel 52 are independently controlled respectively, and in the present embodiment, by independently controlling the first cooling water channel 51 and the second cooling water channel 52 respectively, more power can be given to the first cooling water channel 51 and the second cooling water channel 52, and the cooling effect of each of the first cooling water channel 51 and the second cooling water channel 52 can be improved, thereby improving the cooling effect of the first cooling layer 5 on the material cake 4 and the overall pressure chamber 1, and improving the service life of the overall pressure chamber 1.

[0039] For further information, see Figure 3 In the present embodiment, the first cooling water channel 51 and the second cooling water channel 52 are both annular water channels. In the present embodiment, the overall pressure chamber 1 is configured as a cylinder. Thus, the first cooling water channel 51 and the second cooling water channel 52 are both configured as annular water channels, which can improve the cooling effect of the first cooling water channel 51 and the second cooling water channel 52 in the overall pressure chamber 1, thereby improving the cooling effect of the first cooling layer 5.

[0040] See also Figure 3 In the present embodiment, the second cooling layer 6 includes a third cooling water channel 61 and a fourth cooling water channel 62 which are arranged in parallel, and the third cooling water channel 61 and the fourth cooling water channel 62 are independently controlled. In the present embodiment, by independently controlling the third cooling water channel 61 and the fourth cooling water channel 62, more power can be given to the third cooling water channel 61 and the fourth cooling water channel 62, and the cooling effect of each of the third cooling water channel 61 and the fourth cooling water channel 62 can be improved, thereby improving the cooling effect of the second cooling layer 6 on the material cake 4 and the movable mold insert 2, and improving the service life of the movable mold insert 2.

[0041] For further information, see Figure 3 In the present embodiment, the third cooling water channel 61 and the fourth cooling water channel 62 are both “bow” shaped water channels. Since the movable mold insert 2 is set as a rectangular block in the present embodiment, the third cooling water channel 61 and the fourth cooling water channel 62 are both set as “bow” shaped water channels, which can improve the cooling effect of the third cooling water channel 61 and the fourth cooling water channel 62 in the movable mold insert 2, thereby improving the cooling effect of the second cooling layer 6.

[0042] See also Figure 3 and Figure 4In the present embodiment, a sprue groove 7 is provided on one side of the overall pressure chamber 1 located at the cake groove 3, and the sprue groove 7 is recessed toward the side away from the movable mold insert 2, wherein the sprue groove 7 corresponds to the die-casting liquid (e.g., aluminum liquid) to form a sprue 8. It can be foreseen that the formed sprue 8 is located on one side of the formed cake 4. It can be foreseen that under the uniform cooling of the first cooling layer 5 and the second cooling layer 6, the die-cast cake 4 is not prone to bursting at the excessive fillet between it and the sprue 8.
