Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically to an adjustable positioning bracket and casting equipment. Background Technology

[0002] Casting equipment is an industrial tool used to pour molten metal or alloy into a mold to form a specific shape. It is widely used in metallurgy, automotive, aerospace and other fields. Depending on the process, casting equipment can be divided into traditional casting and advanced casting types.

[0003] In existing technology, the installation method of fixing the stopper rod above the insulation cover in the casting equipment involves first positioning the stopper rod relative to the inlet, and then welding the insulation cover to the chute. During the welding process, the insulation cover and chute are affected by high temperature and stress, causing the stopper rod's positioning to deviate. This affects the fit clearance between the stopper rod and the inlet, making it impossible for the stopper rod to effectively control the liquid flow. Furthermore, because the insulation cover and chute are welded together, the position of the stopper rod installed on the insulation cover cannot be adjusted, and there are cleaning dead zones between the insulation cover and the chute, making thorough cleaning impossible. This results in a gap between the stopper rod and the inlet, hindering precise flow control of the medium. Utility Model Content

[0004] In view of this, the present invention provides an adjustment positioning bracket and casting equipment to solve the problem that the existing stopper rod fixing structure cannot accurately position the stopper rod and the injection port, resulting in the inability to accurately control the flow of the medium.

[0005] In a first aspect, this utility model provides an adjustment and positioning bracket, comprising:

[0006] The support structure includes at least two support members, which are respectively disposed on both sides of the chute and are detachably connected to the chute. The two support members together form a positioning cavity.

[0007] An adjustment structure includes at least two adjustment members and a mounting member. The two adjustment members are slidably connected to a support member, and the mounting member is disposed between the two adjustment members. Both ends of the mounting member are slidably connected to an adjustment member. The mounting member has a mounting portion that communicates with the positioning cavity. The mounting portion is used to install the stopper rod structure into the positioning cavity.

[0008] The connection structure includes at least two third connectors, each corresponding to one end of the mounting member and one of the adjusting members. The third connectors are adapted to penetrate the mounting member and be threadedly connected to it. The penetrating end of the third connector is adapted to abut against the adjusting member so that, under the action of an external force, the third connectors drive the end of the mounting member away from the adjusting member.

[0009] Beneficial effects: Through the support structure connected to the chute and the adjustment and connection structures set on the support structure, the position of the stopper rod structure can be adjusted by the adjustment structure when it is installed on the adjustment structure, so that the stopper rod structure can correspond to the injection port on the chute, thereby improving the positioning accuracy of the stopper rod structure.

[0010] In one alternative embodiment, the adjusting member is adapted to slide relative to the support member in a first direction under the action of an external force, and the mounting member is adapted to slide relative to the adjusting member in a second direction under the action of an external force.

[0011] Beneficial effects: By setting the adjustment member to slide relative to the support member in the first direction under the action of external force, the support member can drive the mounting member of the adjustment member installed on it to move synchronously in the first direction, thereby adjusting the position of the stopper rod structure in the first direction. The mounting member can slide relative to the adjustment member in the second direction, so that the adjustment member can drive the mounting member installed on it to move synchronously in the second direction, thereby adjusting the position of the stopper rod structure in the second direction.

[0012] In one optional embodiment, the first direction is the direction in which one of the adjusting members moves toward another adjusting member, the second direction is the direction in which the mounting member slides perpendicular to the first direction on the same horizontal plane, and the direction in which the end of the mounting member moves away from the adjusting member is a third direction. The first direction, the second direction, and the third direction are arranged perpendicular to each other in pairs.

[0013] Beneficial effects: By setting the first direction as the direction in which one adjusting component faces another adjusting component, setting the second direction as the direction in which the mounting component slides perpendicular to the first direction on the same horizontal plane, setting the third direction as the direction in which the end of the mounting component moves away from the adjusting component, and setting the first direction, the second direction, and the third direction to be perpendicular to each other, the stopper rod structure mounted on the mounting component can be positioned in the first direction, the second direction, and the third direction, thereby enabling the stopper rod structure to be accurately positioned relative to the injection port on the chute.

[0014] In one optional embodiment, the support member has a plurality of spaced-apart connecting portions along a first direction, and any one of the adjusting members has an adjusting portion along the first direction that corresponds to all of the connecting portions;

[0015] The connection structure further includes a first connector, which is adapted to pass through the adjustment portion and connect to any of the connection portions. The first connector has a first fastened state that fixes the support and the adjustment portion, and a first loosened state that loosens the support and the adjustment portion.

[0016] Beneficial effects: The connecting part on the support, the adjusting part on the adjusting part, and the connecting structure also include a first connecting part. In this embodiment, the connecting part, the adjusting part, and the first connecting part are respectively a connecting hole, an adjusting slot hole, and a first bolt. All the connecting parts are spaced apart along the first direction, and the adjusting part is correspondingly arranged with all the connecting parts. In this way, when the adjusting part is installed on the support, the adjusting part can cover all the connecting parts.

[0017] The first connector has a first fastened state and a first loosened state. In the first fastened state, the first connector can pass through the adjustment part and connect with any connection part, thereby connecting and fixing the adjustment part and the support part together. In the first loosened state, the first connector can exit the connection part, making the adjustment part and the support part movable. Thus, under the action of external force, the adjustment part can slide relative to the support part in the first direction, thereby adjusting the position of the stopper rod structure in the first direction.

[0018] In one optional embodiment, any of the adjusting members has a plurality of spaced fixing portions along the second direction, and the mounting member has sliding portions along the second direction corresponding to all of the fixing portions;

[0019] The connection structure further includes a second connector adapted to pass through the sliding portion and connect to any of the fixed portions. The second connector has a second fastened state that fixes the mounting member and the adjusting member, and a second loosened state that loosens the mounting member and the adjusting member.

[0020] Beneficial effects: By using a fixing part on the adjusting member, a sliding part on the mounting member, and a connecting structure including a second connecting member, the fixing part, the sliding part, and the second connecting member in this embodiment are respectively a fixing hole, a sliding groove hole, and a second bolt. All the fixing parts are spaced apart on the adjusting member along the second direction, and all the fixing parts are arranged to avoid the adjusting part. The sliding part is arranged corresponding to all the fixing parts. In this way, when the adjusting member is mounted on the mounting member, the sliding part can cover all the fixing parts.

[0021] The second connector has a second fastened state and a second loosened state. In the second fastened state, the second connector can pass through the sliding part and connect with any fixed part, thereby connecting and fixing the mounting part and the adjusting part together. In the second loosened state, the second connector can exit the fixed part, making the mounting part and the adjusting part movable. Thus, under the action of external force, the mounting part can slide relative to the adjusting part in the second direction, thereby adjusting the position of the stopper rod structure in the second direction.

[0022] In one alternative embodiment, the mounting member has a plurality of through portions, and any of the third connecting members is threadedly connected to one of the through portions.

[0023] Beneficial effects: By creating a through-hole in the mounting component, which in this embodiment is a through-threaded hole, the through-hole is specifically created at the end of the mounting component, and the through-holes at the two ends of the mounting component are correspondingly arranged. Each through-hole can be threadedly connected to a third connector. When the third connector is threadedly connected to the through-hole, the through-hole end of the third connector can abut against the adjusting component. Thus, under the action of external force, the third connector can resist the rotation of the adjusting component relative to the mounting component, thereby allowing the end of the mounting component to move relative to the adjusting component in the third direction, thereby realizing the adjustment of the position of the stopper rod structure in the third direction.

[0024] In one alternative embodiment, the support member includes an interconnected adapter and a support portion, the adapter and the support portion being vertically arranged, the adapter being adapted to connect with the chute, and all the connecting portions being formed on the support portion.

[0025] Beneficial effects: By setting the support component including a transition part and a support part, in this embodiment the transition part and the support part are a transition plate and a support plate, respectively. The transition part and the support part are interconnected and specifically arranged vertically. The transition part can be connected to the chute to connect the support component to the chute. All the connecting parts are opened on the support part, so that the support component can be connected to the adjusting part through the supporting part with the connecting parts, and provide support for the adjusting part, the mounting part and the stopper rod structure.

[0026] Secondly, this utility model also provides casting equipment, including a chute, a stopper rod structure, and the aforementioned adjustment and positioning bracket.

[0027] Beneficial effects: By setting up casting equipment including a chute, a stopper structure and the aforementioned adjustment and positioning bracket, that is, by connecting the adjustment and positioning bracket to the chute and installing the stopper structure on the adjustment and positioning bracket, the positioning accuracy between the stopper structure and the injection port on the chute can be improved by adjusting the positioning bracket.

[0028] In an optional embodiment, a heat-insulating cover is further included, the heat-insulating cover being disposed within the positioning cavity, the heat-insulating cover having a heat-insulating cavity and a relief portion communicating with the heat-insulating cavity, the heat-insulating cover being adapted to be fitted onto the stopper rod of the stopper rod structure through the relief portion.

[0029] Beneficial effects: The casting equipment also includes a heat preservation cover, which is specifically set in the positioning cavity formed between the adjustment positioning bracket and the chute. The heat preservation cover has a heat preservation cavity and a relief part connected to the heat preservation cavity. In this embodiment, the relief part is a relief hole. The heat preservation cover is specifically fitted onto the stopper rod of the stopper rod structure through the relief part. In this way, the medium can be kept warm through the heat preservation cavity.

[0030] In one alternative embodiment, when the heat-insulating cover is disposed within the positioning cavity, the heat-insulating cover abuts against the chute.

[0031] Beneficial effects: By setting the insulation cover between the insulation cover and the chute, when the insulation cover is set in the positioning cavity, the insulation cover can slide relative to the stopper rod of the stopper rod structure through the relief part. In this way, the upper surface of the chute can be exposed, so that the staff can thoroughly clean the chute and avoid debris from blocking the inlet on the chute, which would affect the accurate control of the medium flow.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0044] According to an embodiment of the present invention, in one aspect, an adjustment positioning bracket is provided, such as... Figures 1 to 6 As shown, the structure includes a support structure 1, an adjustment structure 2, and a connecting structure. The support structure 1 includes at least two support members 11, which are respectively disposed on both sides of the chute 4 and are detachably connected to the chute 4. The two support members 11 together form a positioning cavity. The adjustment structure 2 includes at least two adjustment members 21 and a mounting member 22. The two adjustment members 21 are slidably connected to a support member 11, and the mounting member 22 is disposed between the two adjustment members 21. Both ends of the mounting member 22 are slidably connected to an adjustment member 21. The mounting member 22 has a mounting portion 221 that communicates with the positioning cavity. The mounting portion 221 is used to install the stopper rod structure 5 into the positioning cavity. The connecting structure includes at least two third connecting members, which correspond to one end of the mounting member 22 and one adjustment member 21, respectively. The third connecting members are adapted to penetrate the mounting member 22 and are threadedly connected to the mounting member 22. The penetrating end of the third connecting member is adapted to abut against the adjustment member 21 so that under the action of external force, the third connecting member drives the end of the mounting member 22 away from the adjustment member 21.

[0045] The aforementioned adjustment and positioning bracket, through the adjustment structure 2 and connecting structure set on the support structure 1, specifically includes two support members 11, which in this embodiment are support frames. The two support members 11 are respectively set on both sides of the chute 4, and the end of each support member 11 is detachably connected to the chute 4. In this way, the support member 11 can be connected or disassembled with the chute 4. At the same time, the two support members 11 together form a positioning cavity. The adjustment structure 2 specifically includes two adjustment members 21 and a mounting member 22. In this embodiment, the adjustment member 21 and the mounting member 22 are respectively an adjustment plate and a mounting plate. The two adjustment members 21 are slidably connected to one support member 11, and the mounting member 22 is set between the two adjustment members 21, with the two ends of the mounting member 22 being... The two adjusting members 21 are slidably connected to each other, so that when an external force is applied, the two adjusting members 21 can slide relative to the two supporting members 11 at the same time, and the mounting member 22 can slide relative to the two adjusting members 21 at the same time, thereby adjusting the position of the mounting member 22. In addition, the mounting member 22 is provided with a mounting part 221 that communicates with the positioning cavity. In this embodiment, the mounting part 221 is a mounting hole. The mounting part 221 is specifically used to install the stopper rod structure 5 into the positioning cavity. Since the position of the mounting member 22 can be adjusted, the position of the stopper rod structure 5 installed in the mounting part 221 on the mounting member 22 can also be adjusted. In this way, the positioning of the stopper rod structure 5 will not be deviated, and the stopper rod structure 5 and the injection port 41 on the chute 4 can cooperate with each other.

[0046] In addition, the connection structure specifically includes two third connectors, which are third screws in this embodiment. The two third connectors correspond to one end of the mounting member 22 and one adjusting member 21, respectively. Each third connector can penetrate the mounting member 22 and be threadedly connected to the mounting member 22. At the same time, when the third connector penetrates the mounting member 22, the penetrating end of the third connector can abut against the adjusting member 21. Thus, under the action of external force, the third connector can rotate relative to the mounting member 22 and drive the end of the mounting member 22 away from the adjusting member 21. This allows the mounting member 22 to drive the stopper rod structure 5 away from the adjusting member 21. Since both ends of the mounting member 22 are provided with third connectors, the level of the mounting member 22 can be adjusted through the third connectors. The stopper rod structure 5 is installed in the mounting part 221 of the mounting member 22, so the level of the stopper rod structure 5 can also be adjusted through the mounting member 22. In this way, the positioning accuracy between the stopper rod structure 5 and the injection port 41 on the chute 4 can be further improved.

[0047] In one embodiment, such as Figure 1 and Figure 2 As shown, the adjusting member 21 is adapted to slide relative to the supporting member 11 in a first direction under the action of an external force, and the mounting member 22 is adapted to slide relative to the adjusting member 21 in a second direction under the action of an external force.

[0048] The aforementioned adjustment and positioning bracket, under the action of external force, allows the adjusting member 21 to slide relative to the support member 11 in the first direction, so that the support member 11 can drive the mounting member 22 of the adjusting member 21 installed thereon to move synchronously in the first direction, thereby adjusting the position of the stopper rod structure 5 in the first direction. The mounting member 22 can slide relative to the adjusting member 21 in the second direction, so that the adjusting member 21 can drive the mounting member 22 installed thereon to move synchronously in the second direction, thereby adjusting the position of the stopper rod structure 5 in the second direction.

[0049] In one embodiment, such as Figure 1 and Figure 2 As shown, the first direction is the direction in which one adjusting member 21 moves toward another adjusting member 21, the second direction is the direction in which the mounting member 22 slides perpendicular to the first direction on the same horizontal plane, and the direction in which the end of the mounting member 22 moves away from the adjusting member 21 is the third direction. The first direction, the second direction and the third direction are arranged perpendicular to each other in pairs.

[0050] The aforementioned adjustment and positioning bracket, by setting the first direction as the direction in which one of the adjusting members 21 faces the other, setting the second direction as the direction in which the mounting member 22 slides perpendicular to the first direction on the same horizontal plane, setting the third direction as the direction in which the end of the mounting member 22 moves away from the adjusting member 21, and setting the first direction, the second direction, and the third direction to be perpendicular to each other, allows the stopper rod structure 5 mounted on the mounting member 22 to be positioned in the first direction, the second direction, and the third direction, thereby enabling the stopper rod structure 5 to be accurately positioned relative to the injection port 41 on the chute 4.

[0051] In one embodiment, such as Figures 2 to 4 As shown, the support member 11 has a plurality of spaced connecting portions 111 along the first direction, and any adjusting member 21 has an adjusting portion 211 along the first direction that corresponds to all the connecting portions 111; the connecting structure also includes a first connecting member, which is adapted to pass through the adjusting portion 211 and connect to any connecting portion 111. The first connecting member has a first fastened state that fixes the support member 11 and the adjusting member 21, and a first loosened state that loosens the support member 11 and the adjusting member 21.

[0052] The adjustment and positioning bracket of the above structure includes a connecting part 111 on the support member 11, an adjusting part 211 on the adjusting member 21, and a first connecting member. In this embodiment, the connecting part 111, the adjusting part 211, and the first connecting member are a connecting hole, an adjusting slot, and a first bolt, respectively. All the connecting members are spaced apart along the first direction, and the adjusting part 211 is correspondingly arranged with all the connecting parts 111. Thus, when the adjusting part 21 is installed on the support member 11, the adjusting part 211 can cover all the connecting parts 111.

[0053] The first connector has a first fastened state and a first loosened state. In the first fastened state, the first connector can pass through the adjustment part 211 and connect with any connection part 111, thereby connecting and fixing the adjustment part 21 and the support part 11 together. In the first loosened state, the first connector can exit the connection part 111, making the adjustment part 21 and the support part 11 movable. Thus, under the action of external force, the adjustment part 21 can slide relative to the support part 11 in the first direction, thereby adjusting the position of the stopper rod structure 5 in the first direction.

[0054] In one embodiment, such as Figures 2 to 5 As shown, any adjusting member 21 has a plurality of spaced fixing portions 212 along the second direction, and the mounting member 22 has sliding portions 222 corresponding to all the fixing portions 212 along the second direction; the connecting structure also includes a second connecting member, which is adapted to pass through the sliding portion 222 and connect to any fixing portion 212. The second connecting member has a second fastened state that fixes the mounting member 22 and the adjusting member 21, and a second loosened state that loosens the mounting member 22 and the adjusting member 21.

[0055] The adjustment and positioning bracket of the above structure, through the fixing part 212 opened on the adjusting member 21, the sliding part 222 opened on the mounting member 22, and the connection structure including the second connecting member, the fixing part 212, the sliding part 222 and the second connecting member are respectively a fixing hole, a sliding groove hole and a second bolt in this embodiment. All the fixing parts 212 are arranged at intervals along the second direction on the adjusting member 21, and all the fixing parts 212 are arranged to avoid the adjusting part 211. The sliding part 222 is arranged corresponding to all the fixing parts 212. In this way, when the adjusting member 21 is installed on the mounting member 22, the sliding part 222 can cover all the fixing parts 212.

[0056] The second connector has a second fastened state and a second loosened state. In the second fastened state, the second connector can pass through the sliding part 222 and connect with any of the fixing parts 212, thereby connecting and fixing the mounting part 22 and the adjusting part 21 together. In the second loosened state, the second connector can exit the fixing part 212, making the mounting part 22 and the adjusting part 21 movable. Thus, under the action of external force, the mounting part 22 can slide relative to the adjusting part 21 in the second direction, thereby adjusting the position of the stopper rod structure 5 in the second direction.

[0057] In one embodiment, such as Figure 5 As shown, the mounting component 22 has several through-holes 223, and any third connector is threadedly connected to one of the through-holes 223.

[0058] The adjustment and positioning bracket of the above structure has a through-hole 223 on the mounting member 22. In this embodiment, the through-hole 223 is a through threaded hole. The through-hole 223 is specifically opened at the end of the mounting member 22, and the through-holes 223 at the two ends of the mounting member 22 are correspondingly arranged. Each through-hole 223 can be threadedly connected to a third connector. When the third connector is threadedly connected to the through-hole 223, the through end of the third connector can abut against the adjusting member 21. Thus, under the action of external force, the third connector can resist the adjustment member 21 from rotating relative to the mounting member 22, thereby allowing the end of the mounting member 22 to move relative to the adjusting member 21 in the third direction, thereby realizing the adjustment of the position of the stopper rod structure 5 in the third direction.

[0059] In one embodiment, such as Figure 3 As shown, the support member 11 includes a connecting part 112 and a support part 113 that are connected to each other. The connecting part 112 and the support part 113 are arranged vertically. The connecting part 112 is adapted to be connected to the chute 4. All the connecting parts 111 are opened on the support part 113.

[0060] The adjustment and positioning bracket of the above structure includes a support member 11 comprising a transition part 112 and a support part 113. In this embodiment, the transition part 112 and the support part 113 are a transition plate and a support plate, respectively. The transition part 112 and the support part 113 are interconnected and specifically arranged vertically. The transition part 112 can be connected to the chute 4 to connect the support member 11 to the chute 4. All the connecting parts 111 are provided on the support part 113, so that the support member 11 can be connected to the adjusting member 21 through the support part 113 with the connecting parts 111, and provide support for the adjusting member 21, the mounting member 22 and the stopper rod structure 5.

[0061] According to an embodiment of the present invention, in another aspect, a casting device is also provided, such as... Figures 1 to 6As shown, it includes a chute 4, a stopper structure 5, and the aforementioned adjustment and positioning bracket.

[0062] The casting equipment with the above structure includes a chute 4, a stopper structure 5, and the aforementioned adjustment and positioning bracket. Specifically, by connecting the adjustment and positioning bracket to the chute 4 and installing the stopper structure 5 on the adjustment and positioning bracket, the positioning accuracy between the stopper structure 5 and the injection port 41 on the chute 4 can be improved by adjusting the positioning bracket.

[0063] In one embodiment, such as Figure 1 As shown, it also includes a heat insulation cover 6, which is disposed in the positioning cavity. The heat insulation cover 6 has a heat insulation cavity and a relief portion that communicates with the heat insulation cavity. The heat insulation cover 6 is adapted to be sleeved on the stopper rod of the stopper rod structure 5 through the relief portion.

[0064] The casting equipment with the above structure also includes a heat insulation cover 6. The heat insulation cover 6 is specifically set in the positioning cavity formed between the adjustment positioning bracket and the chute 4. The heat insulation cover 6 has a heat insulation cavity and a relief part connected to the heat insulation cavity. In this embodiment, the relief part is a relief hole. The heat insulation cover 6 is specifically fitted onto the stopper rod of the stopper rod structure 5 through the relief part. In this way, the medium can be kept warm through the heat insulation cavity.

[0065] In one embodiment, such as Figure 1 As shown, when the heat insulation cover 6 is placed in the positioning cavity, the heat insulation cover 6 abuts against the chute 4.

[0066] The casting equipment with the above structure is positioned between the insulation cover 6 and the chute 4 to form an abutment. When the insulation cover 6 is placed in the positioning cavity, it can slide relative to the stopper rod of the stopper rod structure 5 through the relief part. In this way, the upper surface of the chute 4 can be exposed, allowing the staff to thoroughly clean the chute 4 and prevent debris from blocking the pouring port 41 on the chute 4, thus affecting the precise control of the medium flow.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
