Description

Technical Field

[0001] This utility model belongs to the field of die casting technology, specifically relating to a die casting equipment with positioning function. Background Technology

[0002] With the rapid development of high-end manufacturing fields such as automobiles, aerospace, and electronic communications, increasingly stringent requirements have been placed on the precision, quality stability, and production efficiency of die-cast parts. As an efficient and low-cost mass production process for metal parts, die casting has become the mainstream production method for core components in the above-mentioned fields (such as automotive gearbox housings, 5G base station radiators, and lightweight aerospace structural parts). Therefore, it is necessary to design a die casting equipment with positioning function.

[0003] Existing traditional die casting equipment mostly relies on manual alignment of molds or a single mechanical positioning structure (such as guidance only through guide pillars). The positioning accuracy is easily affected by human operation errors, mold wear or equipment vibration, often resulting in problems such as misalignment between the upper and lower mold mechanisms and poor cavity fit. This leads to defects such as flash, missing material, and dimensional deviations in die-cast parts, resulting in a generally high defect rate. Utility Model Content

[0004] The purpose of this utility model is to provide a die-casting molding equipment with positioning function that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A die-casting molding equipment with positioning function includes a load-bearing component. The load-bearing component includes an operating table. A positioning mounting component is fixedly installed at the bottom of the operating table. A die-casting component that cooperates with the positioning mounting component is fixedly installed on the top of the operating table. A feed pipe that cooperates with the die-casting component is fixedly connected to the inside of the die-casting component.

[0007] As a further optimization of this utility model, a bearing plate is fixedly installed on both sides of the bottom of the operating table, and guide columns are fixedly installed at the four corners of the top of the operating table. The top of the multiple guide columns is jointly installed with an installation top plate placed above the operating table. A positioning hole is opened in the middle position inside the operating table, and guide grooves are opened in the middle position of both sides inside the operating table.

[0008] As a further optimization of this utility model, the positioning and mounting assembly includes a servo motor fixedly located on one side of a support plate. The output end of the servo motor is fixedly mounted with a bidirectional screw that is rotatably connected to another support plate through a support plate. The two sides of the bidirectional screw are symmetrically threaded with guide rods placed inside guide slots. The tops of the two guide rods are fixedly mounted with positioning clamps that are slidably placed on the top of the operating table, and the two positioning clamps cooperate with each other.

[0009] As a further optimization of this utility model, a fixed rod is slidably passed through the middle position inside both guide rods, and a spring connected to the guide rod is fixedly sleeved on the outer side of the two fixed rods that are close to each other.

[0010] As a further optimization of this utility model, the die-casting assembly includes a hydraulic cylinder fixedly located at the middle position of the top of the mounting plate. The output end of the hydraulic cylinder passes through the mounting plate and is fixedly mounted with an upper mold mechanism. Both sides of the upper mold mechanism are threadedly fixedly mounted with fixed guide blocks that slide and fit around the guide column. The feed pipe is connected to one side of the interior of the upper mold mechanism.

[0011] As a further optimization of this utility model, a positioning post is inserted into the positioning hole, and a lower mold mechanism is fixedly installed on the top of the positioning post, which is located on the top of the operating table and directly below the upper mold mechanism. The lower mold mechanism is placed inside the two positioning clamps and cooperates with them. Fixing holes that cooperate with fixing rods are opened at the bottom of both sides of the positioning post.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model fundamentally improves positioning accuracy through a composite positioning system of "preliminary positioning + precise clamping". Preliminary positioning is more precise: In the die casting assembly, the lower mold mechanism is precisely inserted into the positioning hole of the operating table through the positioning column at the bottom, so as to achieve preliminary rigid positioning of the lower mold mechanism and avoid the error of traditional manual alignment. Clamping positioning is without deviation: The servo motor drives the bidirectional screw to drive the positioning clamping plate to move in opposite directions. With the guide groove limiting the guide connecting rod, the clamping force of the positioning clamping plate can be evenly distributed and the displacement accuracy controlled, so as to ensure that the lower mold mechanism has no offset or tilt during the clamping process.

[0014] 2. This utility model achieves "semi-automatic positioning + quick mold change" through structural optimization, greatly reducing manual intervention. Mold installation does not require manual alignment: the positioning pin of the lower mold mechanism and the positioning hole of the operating table form a "self-guiding" structure. The operator only needs to align the positioning pin with the positioning hole and place it gently to complete the initial positioning without repeated adjustments. The clamping process is automated: after the servo motor is started, the bidirectional screw can automatically drive the positioning clamp to complete the clamping or releasing action. With the torque feedback function of the servo motor, the clamping position can be automatically identified (the machine will stop automatically when the torque reaches the preset threshold), without the need for manual judgment of the clamping degree.

[0015] 3. Through the structural design of the fixing rod and spring, this utility model can not only achieve the clamping operation of the positioning clamping plate, but also drive the positioning column to move towards the positioning column in the lower mold mechanism, so as to facilitate the fixing rod to be inserted into the fixing hole in the positioning column. This can complete the secondary fixing and limiting work of the lower mold mechanism, improve the stability of the later positioning, and through the elastic structure design of the spring, it can also facilitate the free movement of the positioning clamping plate in the later stage, adapt to the clamping and positioning of different models of lower mold mechanisms, and increase the convenience and flexibility of the lower mold mechanism positioning in the later stage of the die casting molding equipment.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, a die-casting molding equipment with positioning function consists of four core parts: a load-bearing component 1, a positioning and mounting component 2, a die-casting component 3, and a feed pipe 4. Each part works together through a specific connection method to achieve precise positioning and efficient operation in the die-casting molding process. Among them, the load-bearing component 1 serves as the basic support structure of the equipment, providing a stable mounting platform for other components; the positioning and mounting component 2 cooperates with the load-bearing component 1 to achieve precise positioning and fixation of the die-casting mold; the die-casting component 3 is installed above the load-bearing component 1 and is responsible for completing the core action of die-casting molding; the feed pipe 4 is connected to the die-casting component 3 to transport raw materials for the die-casting process.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, the load-bearing component 1 includes an operating platform 100, which is a rectangular metal plate structure with high load-bearing capacity. On both sides of the bottom of the operating platform 100, a bearing plate 102 is fixedly installed by welding. The bearing plate 102 is set perpendicular to the operating platform 100 and the two bearing plates 102 are symmetrically distributed to provide stable bottom support for the operating platform 100 and prevent the operating platform 100 from tilting or shaking during operation. At the four corners of the top of the operating platform 100, guide columns 101 are fixedly installed by bolts. The guide columns 101 are cylindrical metal rods with a height greater than the working stroke of the subsequent die-casting component 3. The top of the four guide columns 101 is bolted together to a mounting top plate 105. The mounting top plate 105 is set parallel to the operating platform 100 and located directly above the operating platform 100, forming a mounting platform on the top of the equipment for fixing the die-casting component 3.

[0025] like Figure 1 , Figure 2 , Figure 3As shown, a circular positioning hole 103 is provided in the middle position inside the operating table 100. The positioning hole 103 penetrates the upper and lower surfaces of the operating table 100 and is used to cooperate with the die-casting component 3 to achieve the initial positioning of the mold. In the middle position of both sides inside the operating table 100, two guide grooves 104 are also symmetrically provided. The length direction of the guide grooves 104 is consistent with the length direction of the operating table 100, and the two ends of the guide grooves 104 do not penetrate the side wall of the operating table 100. They are used to provide guidance for the movement of the positioning and installation component 2. At the same time, limit grooves are provided at both ends inside the guide grooves 104.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the positioning and mounting assembly 2 cooperates with the operating table 100 and the support plate 102 in the load-bearing assembly 1. On one side of one of the support plates 102, a servo motor 200 is fixedly mounted by bolts. The output end of the servo motor 200 rotates through the interior of one of the support plates 102, and its output shaft is fixedly connected to one end of a bidirectional screw 201 through a coupling. The other end of the bidirectional screw 201 is rotatably connected to another support plate 102 through a bearing, so that the bidirectional screw 201 can rotate stably around its own axis under the drive of the servo motor 200. The axis of the bidirectional screw 201 is consistent with the length direction of the operating table 100 and is located directly below the operating table 100.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a guide rod 203 is threaded onto each of the two sides of the bidirectional screw 201. The top of the guide rod 203 extends upward and passes through the guide groove 104 on the operating table 100 and is placed on the top of the operating table 100. Limiting blocks are fixedly installed at the top of both ends of the two guide rods 203, and the limiting blocks extend into the limiting slide grooves opened at both ends inside the guide groove 104. Through the sliding design of the limiting blocks and limiting slide grooves, the stability of the guide rods 203 during subsequent sliding installation is improved. Since the threads on both sides of the bidirectional screw 201 turn in opposite directions, when the bidirectional screw 201 rotates, the two guide rods 203... The connecting rods 203 can move towards or away from each other along the axis of the bidirectional screw 201 under the constraint of the guide groove 104. At the top of each of the two guide connecting rods 203, a positioning clamping plate 202 is fixedly installed by bolts. The positioning clamping plate 202 is a metal plate, and the opposite surfaces of the two positioning clamping plates 202 are provided with V-shaped opening grooves and anti-slip textures. The two positioning clamping plates 202 are located on the top of the operating table 100 and slide together to clamp and fix the subsequent lower mold mechanism 303. The design of the V-shaped opening groove can realize the fixed clamping and positioning of lower mold mechanisms 303 of different shapes.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, in addition, a fixed rod 204 is slidably inserted through the middle position inside the two guide rods 203. The axis of the fixed rod 204 is parallel to the axis of the bidirectional screw 201. On the side of the two fixed rods 204 that are close to each other, a spring 205 is fixedly fitted. One end of the spring 205 is fixedly connected to the side wall of the guide rod 203, and the other end is fixedly connected to the limiting block on the fixed rod 204. The spring 205 can provide the guide rod 203 with elastic force toward the middle position of the bidirectional screw 201, which facilitates the secondary positioning of the lower mold mechanism 303 of different sizes in the later stage.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the die-casting component 3 is fixedly installed below the mounting top plate 105 in the load-bearing component 1. At the middle position of the top of the mounting top plate 105, a hydraulic cylinder 300 is fixedly installed by bolts. The output end of the hydraulic cylinder 300 is set downward, and its piston rod passes through the through hole on the mounting top plate 105 and is fixedly connected to the top of the upper mold mechanism 301 through a flange. The upper mold mechanism 301 is the upper mold part of the die-casting, which has a die-casting cavity and a feeding channel inside, and can move up and down in the vertical direction under the drive of the hydraulic cylinder 300.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, fixed guide blocks 302 are fixedly installed on both sides of the upper mold mechanism 301 by bolts. The fixed guide block 302 has through holes that match the guide post 101. The fixed guide block 302 is slidably fitted on the outside of the guide post 101. When the hydraulic cylinder 300 drives the upper mold mechanism 301 to move up and down, the fixed guide block 302 can slide along the axial direction of the guide post 101 to provide guidance for the movement of the upper mold mechanism 301 and ensure the stability and accuracy of the upper mold mechanism 301 during the movement process.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a positioning pin 304 is inserted into the positioning hole 103 on the operating table 100. The outer diameter of the positioning pin 304 matches the inner diameter of the positioning hole 103, allowing the positioning pin 304 to be stably inserted into the positioning hole 103 for initial positioning. A lower mold mechanism 303 is bolted to the top of the positioning pin 304. The lower mold mechanism 303 is a die-cast lower mold part that matches the cavity of the upper mold mechanism 301. The lower mold mechanism 303 is located at the top of the operating table 100, directly below the upper mold mechanism 301. Simultaneously, the lower mold mechanism 303... 03 is placed inside the two positioning clamps 202 and cooperates with them. When the positioning clamps 202 move towards each other, they can clamp and fix the lower mold mechanism 303. A fixing hole 305 is opened at the bottom of both sides of the positioning post 304. The diameter of the fixing hole 305 matches the diameter of the fixing rod 204. When the positioning post 304 is inserted into the positioning hole 103, the positioning clamps 202 can drive the fixing rod 204 to be inserted into the fixing hole 305, thereby further fixing the positioning post 304 and preventing the positioning post 304 from shifting during operation.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the feed pipe 4 is a metal pipe. One end of it is fixedly connected to the external raw material conveying equipment through a flange, and the other end is fixedly connected to one side of the upper mold mechanism 301 through welding or threaded connection. The feed pipe 4 is connected to the feed channel inside the upper mold mechanism 301, which can stably transport external die casting raw materials such as molten metal to the cavity of the upper mold mechanism 301, providing raw materials for the die casting process.

[0033] It should be noted that in this die-casting molding equipment with positioning function, firstly, the positioning pin 304 at the bottom of the lower mold mechanism 303 is aligned with the positioning hole 103 on the operating table 100, and the positioning pin 304 is inserted into the positioning hole 103 to complete the initial positioning of the lower mold mechanism 303. Then, the servo motor 200 in the positioning mounting assembly 2 is started. The servo motor 200 drives the bidirectional screw 201 to rotate around its own axis. Since the threads on both sides of the bidirectional screw 201 turn in opposite directions, and the guide connecting rod 203 is threadedly connected to the bidirectional screw 201 and cannot rotate with the bidirectional screw 201 due to the restriction of the guide through groove 104, the two guide connecting rods 203 will move towards each other along the axial direction of the bidirectional screw 201, causing the positioning clamp 202 on its top to move synchronously towards each other until positioning is achieved. The inner side of the clamping plate 202 fits tightly against the side wall of the lower mold mechanism 303, thereby clamping and fixing the lower mold mechanism 303. The servo motor 200 is turned off. At the same time, during the movement of the guide rod 203, the fixed rod 204 and the spring 205 can also move towards the positioning post 304. Then, the fixed rod 204 can be inserted into the fixing holes 305 on both sides of the positioning post 304 to facilitate the secondary fixing of the lower mold mechanism 303. In addition, during the subsequent positioning and clamping of lower mold mechanisms 303 of different sizes by the continuous movement of the guide rod 203, the spring 205 can also be compressed, while the fixed rod 204 remains unchanged. This provides flexible adaptability for the positioning clamping plate 202 to fix lower mold mechanisms 303 of different sizes in the later stage.

[0034] The hydraulic cylinder 300 in the die-casting assembly 3 is activated, and the piston rod of the hydraulic cylinder 300 extends downward, driving the upper mold mechanism 301 to move downward in the vertical direction. During this process, the fixed guide blocks 302 on both sides of the upper mold mechanism 301 slide downward synchronously along the axis of the guide column 101, providing guidance for the movement of the upper mold mechanism 301. When the bottom of the upper mold mechanism 301 is tightly fitted with the top of the lower mold mechanism 303, the hydraulic cylinder 300 is closed. At this time, the upper mold mechanism 301 and the lower mold mechanism 303 together form a complete die-casting assembly. The die-casting cavity is formed by pressurizing and conveying molten die-casting material to the feed pipe 4 through an external material conveying device. The material enters the feeding channel inside the upper mold mechanism 301 through the feed pipe 4 and finally fills the die-casting cavity formed by the upper mold mechanism 301 and the lower mold mechanism 303. After the material in the cavity cools and solidifies, the hydraulic cylinder 300 is activated again to retract the piston rod of the hydraulic cylinder 300 upward, which drives the upper mold mechanism 301 to move upward and reset. Then, the solidified material can be removed from the lower mold mechanism 303.

[0035] When it is necessary to replace the lower mold mechanism 303, the servo motor 200 can be started to make the bidirectional screw 201 rotate in the opposite direction, which will drive the two positioning clamps 202 to move in opposite directions, loosening the clamping of the lower mold mechanism 303. Furthermore, through the guide rod 203, the fixing rod 204 and the spring 205 can also be moved and disengaged into the fixing hole 305. Finally, the lower mold mechanism 303 can be removed, completing the replacement operation.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
