Die casting molds

Abstract

This application relates to a die-casting mold. The die-casting mold includes at least a base and a mold core assembly. The mold core assembly includes a fixed mold core and a movable mold core. The movable mold core can move closer to or further away from the fixed mold core via an opening along a first direction, allowing the die-casting mold to switch between a closed state and an open state. This facilitates better formation of the die-casting part within the die-casting cavity defined by the movable and fixed mold cores, and facilitates better removal of the completed die-casting part. By providing a reinforcing portion on the first sidewall of the fixed mold core, and housing the reinforcing portion within a recess on the first cavity wall of the receiving cavity, the fixed mold core can be more stably housed within the receiving cavity, improving the stability of the die-casting process. Simultaneously, the reinforcing portion can increase the stress and structural strength of the mold core assembly during die-casting with the mold closed, reducing deformation of the die-casting part due to structural instability of the mold core assembly during the die-casting process, thus improving the quality of the die-casting part.

[0063] Please refer to Figures 1 to 5 An embodiment of this application provides a die-casting mold 100, which includes a base 110 and a mold core assembly 120.

[0064] Specifically, the base 110 has a receiving cavity Q and an opening k communicating with the receiving cavity Q. The mold core assembly 120 includes a fixed mold core 121 and a movable mold core 122. The fixed mold core 121 is received within the receiving cavity Q, and the movable mold core 122 is configured to move closer to or further away from the fixed mold core 121 along a first direction F1 via the opening k, so that the die-casting mold 100 can switch between a closed mold state and a closed mold state. In the closed mold state, the movable mold core 122 and the fixed mold core 121 enclose and define the die-casting cavity. In the open mold state, the movable mold core 122 and the fixed mold core 121 are separated from each other.

[0065] The base 110 can be in the shape of a cuboid or a cube, and can be set according to the actual situation. No specific restrictions are imposed here.

[0066] The accommodating cavity Q is used to accommodate the fixed mold core 121, providing space for its installation and placement. The opening k is connected to the accommodating cavity Q, allowing the moving mold core 122 to move closer to or further away from the fixed mold core 121 along the first direction F1, thereby enabling the switching between the mold closing state and the mold opening state.

[0067] It should be noted that the size and shape of the receiving cavity Q can be set according to the size and shape of the mold core assembly 120. The shape of the receiving cavity Q can be a cuboid, a cube, or an irregular shape, etc., and no specific restrictions are imposed here. Figure 2 As shown, the cavity Q is rectangular in shape. Furthermore, as... Figure 2 The diagram illustrates the separation of the mold core assembly 120 from the receiving cavity Q, and the movement of the support member 130 (mentioned later) along the first direction F1, to illustrate the support structure at the bottom of the mold core assembly 120 for ease of explanation. In practical applications, the mold core assembly 120 is located within the receiving cavity Q in the mold-closed state, and the support member 130 (mentioned later) supporting the moving mold core 122 along the first direction F1 may not be located within the receiving cavity Q. Figure 3 The diagram illustrates the mold core assembly 120 in the die-casting mold 100, specifically the moving mold core 122 and the fixed mold core 121 enclosed together. Figure 4As shown, the three-dimensional structure of the venting channel d and the pouring channel z mentioned later is omitted, which are part of the cover of the die-casting mold 100, so as to illustrate the internal structure of the receiving cavity Q.

[0068] The moving mold core 122 can approach the fixed mold core 121 along the first direction F1 through the opening k, thereby placing the moving mold core 122 and the fixed mold core 121 in a closed state. The die-casting cavity defined by the moving mold core 122 and the fixed mold core 121 can be accommodated in the receiving cavity Q, facilitating the subsequent injection of molten metal or the like into the die-casting cavity, thus forming a die-casting part within the die-casting cavity. After the die-casting part is formed, the moving mold core 122 can move away from the fixed mold core 121 along the first direction F1 through the opening k, thereby placing the moving mold core 122 and the fixed mold core 121 in an open state. The die-casting part moves away from the fixed mold core 121 along the moving mold core 122, facilitating the removal of the die-casting part from the die-casting mold 100. It should be noted that the die-casting mold 100 may be equipped with an ejection mechanism, which can be used to eject the die-casting part from the moving mold core after die-casting is completed, thereby better removing the die-casting part. The ejection mechanism is not shown in the figure. Existing ejection mechanisms can be referenced for implementation. The ejection mechanism is not the focus of this case and will not be elaborated here.

[0069] The cavity Q has a first cavity wall q1 surrounding the opening k, the mold core 121 has a first side wall 121a that contacts the first cavity wall q1, the first side wall 121a has a reinforcing part s, the first cavity wall q1 has a first recessed part a1 that matches the reinforcing part s, and the reinforcing part s is housed in the first recessed part a1.

[0070] The reinforcing portion s on the first sidewall 121a is adapted to the first recess a1 on the first cavity wall q1, and the reinforcing portion s can be housed within the first recess a1. Correspondingly, the shape and size of the reinforcing portion s can be adapted to the shape and size of the first recess a1, so as to better house the reinforcing portion s within the first recess a1.

[0071] By cooperating with the reinforcing part s and the first recessed part a1, the fixed mold core 121 can be more stably fixed on the base 110, thereby making the fixed mold core 121 more stably housed in the receiving cavity Q. This facilitates the subsequent closing of the fixed mold core 121 and the moving mold core 122, improving the stability of the die casting process. Simultaneously, a reinforcing part a is provided on the first sidewall 121a of the fixed mold core 121. The reinforcing part a cooperates with the first recessed part a1 on the base 110, enhancing the structural strength of the mold core assembly 120. This increases the stress strength of the mold core assembly 120 during die casting in the closed state, reducing the deformation of the mold core assembly 120 and thus reducing the deformation of the die casting, improving the quality of the die casting.

[0072] In this way, by setting the moving mold core 122 to move closer to or further away from the fixed mold core 121 along the first direction F1 via the opening k, the die-casting mold 100 can switch between a closed state and a closed state, so as to better form the die-casting part within the die-casting cavity defined by the moving mold core 122 and the fixed mold core 121, and to better remove the die-casting part after die casting. At the same time, by providing a reinforcing part s on the first side wall 121a of the fixed mold core 121, and the reinforcing part s being adapted to the first recess a1 on the first cavity wall q1 of the receiving cavity Q, the fixed mold core 121 can be fixed within the receiving cavity Q by accommodating the reinforcing part s within the first recess a1, thereby improving the stability of the die-casting process. When die casting is performed in the mold-closed state, the reinforcement s can also increase the stress strength and structural strength of the mold core assembly 120, so as to reduce the deformation of the die casting caused by structural instability of the mold core assembly during the die casting process. It can better resist the action of various forces that may occur during the die casting process, thereby improving the stability of the mold core assembly 120, reducing the occurrence of adverse conditions such as deformation of the mold core assembly 120, improving the quality of the die casting, and benefiting the production of die castings.

[0073] In some embodiments, please refer to Figure 2 and Figure 3 The first sidewall 121a includes a first wall b1 and a second wall b2 disposed opposite to each other along the second direction F2.

[0074] Specifically, both the first wall b1 and the second wall b2 are provided with multiple reinforcing parts s, and at least some of the reinforcing parts s on the same wall are arranged intersectingly. Among them, the first direction F1 and the second direction F2 are perpendicular to each other.

[0075] The first wall b1 and the second wall b2 are arranged opposite each other along the second direction F2, and both the first wall b1 and the second wall b2 are provided with multiple reinforcing parts s. This strengthens the structural strength of the first wall b1 and the second wall b2 when the mold core assembly 120 is housed in the receiving cavity Q, better coping with the external forces generated during die casting and reducing the risk of deformation or damage to the first wall b1 and the second wall b2 due to excessive force. This is beneficial for the normal use of the mold and improves the quality of the die casting. In this embodiment, the other two walls of the first side wall 121a can be provided with vents e (mentioned later) to discharge the gas generated during die casting and reduce the risk of porosity and looseness in the die casting. It should be noted that in some other embodiments, multiple reinforcing parts s can also be provided on the other walls of the first side wall 121a, depending on the actual situation, and no specific limitations are made here.

[0076] The fact that at least some of the reinforcing parts s located on the same wall intersect means that on the first wall b1 or the second wall b2, some of the reinforcing parts s located on the same wall may intersect, while others may not intersect; alternatively, all the reinforcing parts s located on the same wall may intersect. The arrangement can be made according to the actual situation and is not specifically limited here. For example, some reinforcing parts s may be transverse, while others may be longitudinal, and these reinforcing parts s will intersect on the first wall b1 or the second wall b2.

[0077] By providing multiple reinforcing parts 's' on both the first wall b1 and the second wall b2, the fixed mold core 121 receives additional support and reinforcement at multiple locations on the first wall b1 and the second wall b2. During the die casting process, the mold core assembly 120 can withstand the high pressure generated during the injection of liquid metal and the impact forces during mold closing and opening. The multiple reinforcing parts 's' on the first wall b1 and the second wall b2 effectively disperse external forces, reducing deformation and damage to the mold core assembly 120 due to excessive local stress, thereby significantly enhancing the overall structural stability of the mold core assembly 120. Furthermore, by intersecting at least some of the reinforcing parts 's' located on the same wall, the fixed mold core 121 can be reinforced from different angles and directions on the first wall b1 and the second wall b2. When an external force is applied to the fixed mold core 121, the intersecting reinforcing parts s can transmit and disperse the external force in different directions, which helps to reduce the occurrence of external force concentration, further reduces the risk of local damage to the fixed mold core 121, and improves the stability of the fixed mold core 121 when subjected to external forces, so as to adapt to the complex stress environment during die casting operations, thereby improving the quality of die castings and contributing to the production of die castings.

[0078] In some embodiments, please refer to Figure 3 The multiple reinforcing parts s include multiple first reinforcing parts s1 and multiple second reinforcing parts s2.

[0079] The first reinforcing part s1 extends along the third direction F3, and the second reinforcing part s2 extends along the first direction F1.

[0080] For the same wall, all first reinforcing parts s1 are arranged at intervals along a first direction F1, and all second reinforcing parts s2 are arranged at intervals along a third direction F3. Each of the first reinforcing parts s1 is connected to any of the second reinforcing parts s2. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other.

[0081] It is understandable that, for the same wall (i.e., the first wall b1 or the second wall b2), all the first reinforcing parts s1 can be arranged at intervals along the first direction F1, and all the second reinforcing parts s2 can be arranged at intervals along the third direction F3. This means that there is a certain interval between each first reinforcing part s1 and each second reinforcing part s2; they are not continuously and tightly arranged together, but rather distributed regularly. In this way, they can provide reinforcement at different locations while making reasonable use of the space on the first wall b1 or the second wall b2. It should be noted that the intervals between all the first reinforcing parts s1 and all the second reinforcing parts s2 can be set according to the actual situation. Furthermore, the intervals between all the first reinforcing parts s1 and all the second reinforcing parts s2 can be evenly distributed or unevenly distributed; no specific restrictions are imposed here.

[0082] Each of the first reinforcing parts s1 is connected to any one of the second reinforcing parts s2, which means that on the same wall surface, each first reinforcing part s1 can be connected to any one of the second reinforcing parts s2, so that the first reinforcing parts s1 and the second reinforcing parts s2 form an interconnected structure on the same wall surface, which can reinforce the wall surface of the mold core 121 from multiple directions and multiple angles.

[0083] For example, with Figure 3 For example, it is shown that each of the first reinforcing parts s1 is connected to any one of the second reinforcing parts s2, which roughly presents a grid-like structure.

[0084] In this way, by setting the first reinforcing part s1 to extend along the third direction F3 and the second reinforcing part s2 to extend along the first direction F1, and on the same wall, all the first reinforcing parts s1 and all the second reinforcing parts s2 are arranged at intervals, and each of the first reinforcing parts s1 is connected to any of the second reinforcing parts s2, when an external force is applied to the fixed mold core 121, the external force can be uniformly transmitted and dispersed through the spaced and interconnected first reinforcing parts s1 and second reinforcing parts s2, which further reduces the risk of damage to the fixed mold core 121 caused by the concentration of external force, extends the service life of the fixed mold core 121, and improves the structural strength of the mold core assembly 120.

[0085] Figure 6 It shows Figure 2 The diagram shows a partially enlarged structural schematic of point A of the die-casting mold; for ease of explanation, only the content relevant to the embodiments of this application is shown.

[0086] In some embodiments, please refer to Figure 6 And continue to refer to Figures 2 to 3An exhaust cavity P is defined between the first side wall 121a and the first cavity wall q1. The first side wall 121a is provided with an exhaust port e that connects the interior of the fixed mold core 121 and the exhaust cavity P.

[0087] Specifically, during the die-casting process, when molten metal is injected into the die-casting cavity defined by the moving mold core 122 and the fixed mold core 121, the air originally present in the cavity, as well as some gases that may be generated during the die-casting process (such as gases generated due to the volatilization of some components in the molten metal), need a channel for discharge. The venting cavity P provides space for gas discharge. A vent e is provided on the first sidewall 121a, and the vent e can connect the interior of the fixed mold core 121 and the venting cavity P. It is understood that the gas generated inside the die-casting cavity during the die-casting process can enter the venting cavity P through the vent e. This prevents the gas inside the die-casting cavity from accumulating inside due to the inability to discharge, which could affect the quality of the die-cast part or cause other problems (such as local deformation of the mold core assembly 120 under gas pressure).

[0088] like Figure 6 As shown, the base 110 is provided with multiple exhaust channels d that are connected to the exhaust chamber P, and the exhaust channels d are provided with slag bags.

[0089] The exhaust channel d can further discharge the gas accumulated in the exhaust chamber P to the outside of the die-casting mold 100. When the gas enters the exhaust chamber P from inside the die-casting cavity through the exhaust port e, it can continue to be discharged outward through the exhaust channel d, so that the gas can be smoothly discharged from the die-casting mold 100 throughout the die-casting process, maintaining the gas pressure balance in the die-casting cavity, which is conducive to the smooth progress of the die-casting operation.

[0090] A slag bag is a component that collects or adsorbs impurities that may be carried during gas discharge, ensuring the unobstructed flow of the exhaust channel d. Specifically, a slag bag is installed in each exhaust channel d to collect impurities that may be carried during gas discharge. During the die-casting process, there may be tiny impurity particles in the molten metal, which may flow with the gas during discharge. The slag bag intercepts and collects these impurities, reducing the likelihood of them re-entering the die-casting cavity or contaminating the surrounding environment after being discharged with the gas. It also reduces the risk of impurities accumulating in the exhaust channel d and clogging it. The slag bag keeps the exhaust channel d unobstructed, allowing for the continuous and smooth discharge of gas from the die-casting cavity.

[0091] The exhaust cavity P defined between the first sidewall 121a and the first cavity wall q1, the exhaust port e on the first sidewall 121a connecting the interior of the fixed mold core 121 to the exhaust cavity P, and the multiple exhaust channels d on the base 110 connected to the exhaust cavity P, can promptly expel air from the die-casting cavity and gases generated during the die-casting process. This reduces quality problems such as porosity and looseness in the die-casting parts caused by gas accumulation, thereby effectively improving the quality of the die-casting parts. Simultaneously, slag pockets are installed within the exhaust channels d to effectively intercept impurities carried during gas expulsion. If impurities accumulate within the exhaust channels d, they can easily cause blockage, affecting the gas expulsion effect.

[0092] In some embodiments, please refer to Continue Figure 6 The exhaust passage d includes a first exhaust section d1 connected to the exhaust chamber P, a second exhaust section d2 connected to the exhaust outlet of the exhaust passage d, and a third exhaust section d3 connecting the first exhaust section d1 and the second exhaust section d2.

[0093] Specifically, the first exhaust section d1 is connected to the exhaust chamber P and can receive the gas discharged from the exhaust chamber P. The first exhaust section d1 is the first flow path of the gas after leaving the exhaust chamber P. The second exhaust section d2 is connected to the outlet of the exhaust channel d. It can be understood that the gas will eventually be discharged to the outside of the die-casting mold 100 through the second exhaust section d2, which can smoothly discharge the gas in the die-casting chamber to the environment outside the mold. The third exhaust section d3 connects the first exhaust section d1 and the second exhaust section d2, which can guide the gas from the first exhaust section d1 to the second exhaust section d2 more smoothly, improving the continuity of the entire exhaust process.

[0094] Along the extension direction of the exhaust channel, the maximum cross-sectional area of ​​the second exhaust section d2 is smaller than the minimum cross-sectional area of ​​the first exhaust section d1, and the maximum cross-sectional area of ​​the first exhaust section d1 is smaller than the minimum cross-sectional area of ​​the third exhaust section d3. The slag enclosure is located within the third exhaust section d3.

[0095] Setting the maximum cross-sectional area of ​​the second exhaust section d2 to be smaller than the minimum cross-sectional area of ​​the first exhaust section d1 reduces unnecessary space occupied by the exhaust channels d and allows for smoother gas discharge from the die-casting cavity. Simultaneously, setting the maximum cross-sectional area of ​​the first exhaust section d1 to be smaller than the minimum cross-sectional area of ​​the third exhaust section d3 allows for better gas discharge from the exhaust cavity P into the first exhaust section d1, which has a larger cross-sectional area than the first exhaust section d1. The larger space in the third exhaust section d3 can accommodate more gas, facilitating gas discharge from the die-casting cavity. Of course, each exhaust channel d can also be interconnected. Gas can flow through the first exhaust section d1 of one exhaust channel d, then through the third exhaust section d3 and the second exhaust section d2, before flowing into the third exhaust section d3 of another exhaust channel d, and finally exiting from the second exhaust section d2 of yet another exhaust channel d. The specific connection method of each exhaust channel d can be set according to the actual situation and is not specifically limited here.

[0096] It should be noted that the third exhaust section d3 can be set to a roughly trapezoidal protruding shape, or it can be set to a gas shape, as long as the maximum cross-sectional area of ​​the third exhaust section d3 is maximized.

[0097] Furthermore, by placing the slag pack inside the third exhaust section d3, when gas flows from the first exhaust section d1 into the third exhaust section d3, the maximum cross-sectional area of ​​the third exhaust section d3 is larger than that of the first exhaust section d1 and the second exhaust section d2. Impurities can be more easily intercepted and collected by the slag pack in the third exhaust section d3, thereby more effectively utilizing the slag pack to intercept impurities and reducing the risk of clogging the exhaust passage d.

[0098] By setting the maximum cross-sectional area of ​​the second venting section d2 to be smaller than the minimum cross-sectional area of ​​the first venting section d1, and setting the maximum cross-sectional area of ​​the first venting section d1 to be smaller than the minimum cross-sectional area of ​​the third venting section d3, gas can be discharged from the mold more effectively, allowing the gas generated during the die-casting process to be discharged more promptly and quickly. Simultaneously, dividing the venting channel d into the first venting section d1, the second venting section d2, and the third venting section d3, with closer connections between each section, better guides gas flow, ensuring that the gas flows orderly from the venting chamber P to the outside of the mold along a predetermined path. The gas flow within the entire venting channel d is more stable and smooth. A slag pocket is placed within the third venting section d3, where a large amount of gas accumulates, making it easier for impurities to be intercepted and collected, thus keeping the venting channel d unobstructed and further ensuring the smooth progress of the die-casting process.

[0099] Figure 7 This illustration shows another portion of the three-dimensional structure of the die-casting mold provided in some embodiments of this application; Figure 8 It shows Figure 7 The diagram shows a partially enlarged structural schematic of point D of the die-casting mold; for ease of explanation, only the content related to the embodiments of this application is shown.

[0100] In some embodiments, please refer to Figure 7 and Figure 8 The base 110 is provided with a pouring channel z that connects to the interior of the fixed mold core 121. For example... Figure 7 The diagram illustrates the case where the fixed mold core 121 in the mold core assembly 120 is housed within the receiving cavity Q.

[0101] During the die casting process, the gating channel z can be the path through which molten metal enters the fixed mold core 121 and then fills the die casting cavity. Through the gating channel z, the high-temperature molten metal material can be more accurately delivered to the appropriate position in the die casting cavity Q, so that the die casting part of the required shape can be formed in the die casting cavity later.

[0102] In this embodiment, the casting channel z on the base 110 can be configured as a main channel connected to multiple auxiliary channels. These auxiliary channels are generally distributed in a tree-like pattern, connecting the top of the fixed mold core 121 and its side walls. Distributing the auxiliary channels in a tree-like pattern allows for control of the flow time difference of the liquid metal within the auxiliary channels, ensuring that the time it takes for the liquid metal to reach the interior of the fixed mold core 121 is approximately the same. This results in more uniform flow of the liquid metal into the die-casting cavity, enabling faster die-casting. In this way, the liquid metal can enter through the main channel and be transported to different positions within the die-casting cavity through the multiple auxiliary channels, which is beneficial for the formation of the die-cast part and improves its quality.

[0103] Of course, the pouring channel z can also be set to other shapes, which can be set according to the actual situation, and no specific restrictions are made here.

[0104] The plane containing the central axis of the accommodating cavity Q is defined as the reference plane. The reference plane has a first side c1 and a second side c2 that are arranged opposite each other in a direction perpendicular to the reference plane. The pouring channel z is located on the first side c1, and the venting channel d is located on the second side c2.

[0105] It is understandable that, with the reference plane as the dividing boundary, two opposing spatial regions can be set in a direction perpendicular to the reference plane, namely the first side c1 and the second side c2.

[0106] The gating channel z is located on the first side c1 of the reference surface, while the venting channel d is located on the second side c2 of the reference surface. During the die casting operation, the gating channel z can introduce liquid metal into the die casting cavity. During the flow of the liquid metal, it can discharge the gas in the die casting cavity and the gas generated during the die casting process into the venting channel d, which is opposite to the gating channel z, thereby reducing the gas in the die casting cavity and improving the quality of the die casting.

[0107] By setting the pouring channel z on the first side c1 and the venting channel d on the second side c2, the pouring channel z and the venting channel d can operate independently, allowing the liquid metal to flow more smoothly into the die-casting cavity through the pouring channel z. At the same time, the venting channel d, which is opposite to the pouring channel z, can more efficiently and smoothly discharge the gas generated during the die-casting process, which helps to reduce the possibility of quality defects such as porosity and looseness in the die-casting parts and improves the stability and reliability of the die-casting mold 100.

[0108] Figure 9 A further three-dimensional structural schematic diagram of the die-casting mold provided in some embodiments of this application is shown; Figure 10 It shows Figure 9 The diagram shows a partially enlarged structural view of point F of the die-casting mold; for ease of explanation, only the content related to the embodiments of this application is shown.

[0109] In some embodiments, please refer to Figure 9 and Figure 10 The die-casting mold 100 also includes a support component 130.

[0110] Specifically, the movable mold core 122 is supported on the support member 130, which is configured to move along a first direction F1. It is understood that the movable mold core 122, placed on the support member 130, can move along the first direction F1 with the support member 130, thereby allowing the movable mold core 122 to move closer to or further away from the fixed mold core 121 along the first direction F1, realizing the switching of the die-casting mold 100 between a closed state and an open state. In this embodiment, a driving device is provided to drive the support member 130 to carry the movable mold core 122 along the first direction F1. The driving device can be a hydraulic mechanism, a cylinder mechanism, etc., and can be set according to actual conditions; no specific limitation is made here. Furthermore, the support member 130 is located inside the die-casting mold 100 to better support the movement of the movable mold core 122 along the first direction F1.

[0111] The carrier 130 has multiple cooling zones 131, and multiple first cooling channels r1 are provided within the carrier 130. Each cooling zone 131 corresponds to at least one first cooling channel r1, and the multiple first cooling channels r1 are configured to be controllably opened or closed respectively. Figure 9As shown, the support member 130 has a cuboid-like protruding structure M, which divides the protruding structure M into cooling areas 131. The first cooling channel r1 can be set inside the protruding structure M to better correspond to each cooling area 131. At the same time, the moving mold core 122 can also be placed on this protruding structure M.

[0112] In addition, such as Figure 9 As shown, the support member 130 is provided with an exhaust channel d so that the bottom of the mold core assembly 120 can be vented when the mold is closed.

[0113] The support component 130 is provided with multiple cooling zones 131, which can be different areas divided into a certain layout on the surface of the support component 130. Each zone can correspond to the cooling requirements of different positions and parts of the die-casting cavity during the die-casting process. Multiple first cooling channels r1 are provided inside the support component 130. The first cooling channels r1 can be channels that cool the die-casting cavity by circulating cooling medium.

[0114] Each cooling zone 131 corresponds to at least one first cooling channel r1. It can be understood that each cooling zone 131 has at least one first cooling channel to provide cooling function for the cooling zone 131 in order to meet the cooling requirements of the cooling zone 131.

[0115] Multiple first cooling channels r1 are configured to be individually and controllably opened or closed. That is, the first cooling channel r1 can be individually controlled via a control device or control system to determine whether it is open for cooling or closed to temporarily eliminate the need for cooling. This allows for more flexible fulfillment of the cooling requirements of the die-casting mold 100 under different conditions, improves cooling efficiency, and also helps to rationally utilize cooling resources and avoid unnecessary energy waste.

[0116] It should be noted that the first cooling channel r1 is located inside the support member 130, meaning that the first cooling channel r1 does not penetrate the cooling area 131, but rather indirectly cools the die-casting cavity. For example... Figure 9 and Figure 10For ease of explanation, the dashed circle in the cooling area 131 represents the approximate location of at least one first cooling channel r1, and does not imply that the first cooling channel r1 penetrates the surface of the cooling area 131. The first cooling channel r1 can be configured in a bend-like structure within the cooling area 131, with the bend structure positioned close to the cooling area 131. Cooling medium is introduced into the inlet of the first cooling channel r1, and as the cooling medium approaches the cooling area, it acts on the cooling area 131 before being discharged through the bend structure. The bend structure can be 90 degrees or other angles, depending on the actual situation, as long as it allows for individual control of the first cooling channel r1, thereby enabling individual control of each cooling area. No specific limitations are imposed here.

[0117] By providing a support member 130 in the die-casting mold 100 to support the moving mold core 122 and enabling the support member 130 to move along the first direction F1, more stable support can be provided for the moving mold core 122. During the die-casting process, the moving mold core 122 frequently performs mold-closing and mold-opening operations, moving closer to or further away from the fixed mold core 121. The support member 130 can ensure that the moving mold core 122 always moves along the first direction F1, reducing the movement deviation or shaking caused by factors such as the moving mold core 122's own structure or external forces. This allows the moving mold core 122 and the fixed mold core 121 to be more accurately aligned, forming a die-casting cavity and thus improving the quality of the die-cast part. At the same time, the support member 130 is provided with multiple cooling zones 131, and each cooling zone 131 corresponds to at least one first cooling channel r1. The multiple first cooling channels r2 are configured to be controllably opened or closed. In this way, each zone can be cooled in a targeted manner according to the actual cooling needs of the die-casting mold 100 during the die-casting process, improving cooling efficiency.

[0118] In some embodiments, please refer to Figure 9 and Figure 10 The support member 130 has multiple second recesses a2 on the side facing the moving mold core 122.

[0119] Specifically, at least a portion of the area where the second recess a2 is located constitutes multiple cooling areas 131. That is, the area where all the second recesses a2 are located can constitute multiple cooling areas 131, or a portion of the area where the second recesses a2 are located can constitute multiple cooling areas 131.

[0120] By providing multiple second recesses a2 and defining at least a portion of the areas containing the second recesses a2 as multiple cooling zones 131, the die-casting parts can be cooled by these cooling zones 131 after some of the areas containing the second recesses a2 are designated as cooling zones 131, thereby meeting the cooling requirements of the die-casting mold 100 during the die-casting process.

[0121] In some embodiments, please refer to Figure 9 and Figure 10 The surface of the support member 130 facing the moving mold core 122 has a plurality of partition edges f protruding.

[0122] All the dividing edges f are connected in a preset connection manner and define all the second recesses a2. Each second recess a2 is enclosed and defined by six dividing edges f, and the same dividing edge f is provided between two adjacent second recesses a2.

[0123] All partition edges f are connected in a preset connection method. This preset connection method can be a specific connection pattern determined during the mold design stage. By connecting the partition edges f in the preset connection method, all the second recesses a2 are defined. Each second recess a2 is enclosed and defined by six partition edges f. It can be understood that each second recess a2 is approximately hexagonal in shape. The same partition edge f is provided between two adjacent second recesses a2, which means that there is a shared partition edge f at the boundary of two adjacent second recesses a2, so that each second recess a2 is both independent and connected to each other. In this way, each second recess a2 is enclosed and defined by six partition edges f, and the same partition edge f is provided between two adjacent second recesses a2. The multiple second recesses a2 are arranged in a generally honeycomb pattern on the side surface of the support member 130 facing the moving mold core 122.

[0124] By providing multiple dividing edges f protruding from the surface of the support member 130 facing the moving mold core 122, and connecting and defining all the second recesses a2 in a preset manner, each second recess a2 can be more clearly and accurately defined. Simultaneously, setting each second recess a2 to be enclosed by six dividing edges f helps to more accurately divide the cooling area 131. The presence of the same dividing edge f between adjacent second recesses a2 can isolate adjacent cooling areas 131. The dividing edges f effectively reduce the mixing and interference of cooling media between adjacent cooling areas 131, allowing each cooling area 131 to be cooled independently, further improving the accuracy and effectiveness of cooling. By protruding multiple partition edges f on the surface of the bearing 130, the partition edges f can withstand a certain amount of external force. During the die casting process, when the bearing is subjected to external forces such as pressure from the mold core 122 and impact force during mold closing and opening, the partition edges can share part of the external force, improve the structural strength of the bearing 130, and reduce the possibility of deformation or damage to the bearing 130 due to force, thereby improving the stability of the bearing 130 and even the entire die casting mold.

[0125] In some embodiments, please continue Figures 7 to 10 The base 110 is provided with a pouring channel z that connects to the interior of the fixed mold core 121.

[0126] Specifically, the distribution density of the cooling zone 131 on the unit area of ​​the support 130 decreases as the distribution distance increases, where the distribution distance is the distance between the unit area and the pouring channel z.

[0127] The distribution density of cooling regions 131 on the support member 130 can refer to the proportion or number of cooling regions 131 occupying a certain unit area region of the support member 130. The distribution density of cooling regions 131 on a unit area region of the support member 130 decreases as the distribution distance increases. In this embodiment, the distribution distance refers to the distance between a unit area region and the pouring channel z. That is, with the pouring channel z as a reference, in unit area regions at different positions on the support member 130, the unit area region closer to the pouring channel z has a relatively higher distribution density of cooling regions; while as the distance from the pouring channel z gradually increases, the distribution density of cooling regions on a unit area region gradually decreases.

[0128] It should be noted that the unit area can be set manually according to the actual situation, and no specific restrictions are imposed here. On the bearing 130, the cooling area 131 far away from the pouring channel z may also be omitted, and can be set according to the actual situation, without specific restrictions.

[0129] Since the gating channel z is the path for liquid metal to enter the fixed mold core 121, the heat generated by the liquid metal flow near the gating channel z has a significant impact, and more cooling zones can effectively improve heat dissipation. As the liquid metal moves away from the gating channel z, the heat impact gradually weakens, and correspondingly, reducing the distribution density of cooling zones can meet the cooling requirements. In this way, cooling resources can be rationally allocated according to the actual heat requirements of different areas during the die casting process, reducing the waste of resources caused by excessive setting of cooling zones 131 in areas far from the gating channel z and with less heat impact. At the same time, a reasonable distribution of cooling zones 131 helps maintain the mold in good condition during the die casting process, reducing problems such as mold deformation caused by local overheating, making the shape and size of the die casting cavity more stable. In addition, a more uniform temperature distribution is also conducive to the uniform solidification of liquid metal in the die casting cavity, reducing the possibility of quality defects such as porosity and looseness in the die casting, and improving the quality of the die casting.

[0130] Figure 11 A partial perspective structural schematic diagram of the die-casting mold provided in some embodiments of this application is shown; Figure 12 It shows Figure 11The diagram shows a three-dimensional structure located on a die-casting mold; for ease of explanation, only content relevant to the embodiments of this application is shown.

[0131] In some embodiments, please refer to Figure 11 and Figure 12 The fixed mold core 121 has a wall portion 121b disposed opposite to the moving mold core 122, and the wall portion 121b is provided with multiple second cooling channels r2. For example... Figure 12 As shown, the wall portion 121b of the fixed mold core 121 covers the base 110 along the first direction F1. The wall portion 121b of the fixed mold core 121 covering the base 110 can better accommodate the fixed mold core 121 in the accommodating cavity Q, reducing the movement or shaking of the fixed mold core 121 relative to the base 110.

[0132] It should be noted that the cooling effect of the second cooling channel r2 near the pouring channel z can be greater than that of the second cooling channel r2 far away from the pouring channel z. This can make the temperature distribution in the die casting process more uniform and reduce the phenomenon of die casting deformation caused by uneven temperature.

[0133] Multiple second cooling channels r2 are provided in the wall portion 121b opposite to the moving mold core 122. During the die casting process, when the liquid metal is injected into the die casting cavity, it releases a large amount of heat, which raises the temperature of the wall portion 121b of the fixed mold core 121. The second cooling channels can remove the heat from the wall portion 121b through heat exchange, thereby achieving the purpose of controlling the temperature of the wall portion 121b. At the same time, they can also cool the liquid metal in the die casting cavity, which helps to form the die casting.

[0134] In some embodiments, please refer to Figure 7 , Figure 8 and Figure 11 The wall 121b is also provided with multiple first channels t1 that connect to the interior of the fixed mold core 121, and the base 110 is provided with a casting channel z that connects to the first channels t1.

[0135] Multiple first channels t1 are provided within the wall portion 121b, which can connect to the interior of the fixed mold core 121. Simultaneously, a pouring channel z connected to the first channels t1 is provided on the base 110. When molten metal flows in through the pouring channel z on the base 110, it can further diffuse and distribute within the fixed mold core along the first channels t1 connected to the pouring channel z, thereby more evenly filling the die-casting cavity.

[0136] By connecting the first channel t1 and the pouring channel z, the liquid metal can enter from the pouring channel z on the base 110 and flow better inside the fixed mold core 121 with the help of the first channel t1 in the wall 121b of the fixed mold core 121, achieving a more uniform pouring effect and improving the quality of the die casting.

[0137] In some embodiments, please refer to Figure 1 The die-casting mold 100 also includes multiple drive mechanisms 140.

[0138] Specifically, a plurality of drive mechanisms 140 are arranged around the periphery of the base 110, and each drive mechanism 140 has an output end 141 that can be close to or away from the periphery of the base 110.

[0139] Each drive mechanism 140 has an output end 141, which is the part of the drive mechanism 140 that generates driving force and outputs it externally. The output end 141 can be close to or far from the periphery of the base 110. When in the mold-closed state, the output end 141 of the drive mechanism 140 moves towards the periphery of the base 110, thereby better supporting the moving mold core 122 and the fixed mold core 121 to form the die-casting cavity, improving the structural strength of the mold core assembly 120 and reducing the deformation of the die-casting part. When in the mold-open state, the output end 141 can move away from the periphery of the base 110, which helps to separate the moving mold core 122 and the fixed mold core 121 so as to remove the die-casting part. At the same time, since the first wall b1 and the second wall b2 of the fixed mold core 121 are provided with reinforcing parts s, when the output end 141 moves away from the periphery of the base 110, the reinforcing parts s can effectively resist the force generated when the peripheral output end 141 leaves, reducing the deformation of the die-casting part when the mold is opened.

[0140] In some embodiments, please refer to Figure 1 , Figure 7 and Figure 12 ,like Figure 1 As shown, the die-casting mold 100 also includes a cover 150. The cover 150 is placed on top of the base 110 along the first direction F1. The cover 150 has an area for the pouring channel z to connect with the outside world so that liquid metal can be poured into the die-casting cavity. The cover 150 can reduce the phenomenon of outside air entering the die-casting cavity, thereby improving the reliability of the die-casting process.

[0141] Accordingly, the ejection mechanism mentioned above for ejecting the die-cast part after die casting can be located inside the housing 160 at the bottom of the base 110, so as to better eject the die-cast part from the support member 130 after die casting, thereby removing the die-cast part. The guide mechanism that cooperates with the ejection mechanism can also be located inside the housing 160 at the bottom of the base 110. Here, the specific guide structure can be set according to the actual situation, and no specific restrictions are made here.

[0142] Similarly, the drive device mentioned above for driving the carrier 130 along the first direction F1 can also be located inside the housing 160 at the bottom of the base 110 to better drive the carrier 130 to move, so that the die-casting mold 100 can switch between the mold-closed state and the mold-open state. The guide mechanism that cooperates with the drive device can also be located inside the housing 160 at the bottom of the base 110. Here, the specific guide structure can be set according to the actual situation, and no specific restrictions are made here.

[0143] By providing a housing 160 at the bottom of the base 110, the base 110 can be supported, and a space is formed at the bottom of the base 110 for the moving mold core 122 and the carrier 130 to move along the first direction F1. It can also provide space for related ejection mechanisms, drive devices and guide mechanisms, thereby making the structure of the die casting mold 100 more compact and improving the reliability of the die casting mold 100.

[0144] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0145] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
