Description

Technical Field

[0001] This utility model relates to the field of die casting technology, and in particular to a high-efficiency die casting equipment for automotive battery end plate castings. Background Technology

[0002] With the development of the automotive industry, especially the rapid development of electric vehicles, the demand for automotive batteries is constantly increasing. This device is used in the die-casting process of automotive battery end plate castings.

[0003] In practical use, similar die-casting equipment still has many defects, such as: the existing die-casting equipment has the problem of inaccurate positioning during the mold closing process, and the existing die-casting equipment lacks an effective buffer structure, which can easily cause the moving mold to generate impact or vibration due to the excessive mold opening speed. Therefore, it is necessary to design a high-efficiency die-casting equipment for automotive battery end plate castings. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-efficiency die-casting equipment for automotive battery end plate castings.

[0005] This utility model is achieved using the following technical solution: a high-efficiency die-casting equipment for automotive battery end plate castings, comprising a fixing assembly, the fixing assembly including a mounting plate, a first fixing seat fixedly mounted on the top and bottom of the outer surface of the mounting plate, guide rods fixedly mounted on the four corners of the outer surface of the mounting plate, a fixing mold fixedly mounted on the side of the guide rod away from the mounting plate, a core fixedly mounted at the center of the outer surface of the fixing mold, and an injection port opened inside the core, further comprising:

[0006] A die-casting assembly, comprising a hydraulic cylinder fixedly mounted on the outer surface of a mounting plate, wherein a movable mold is fixedly connected to the output end of the hydraulic cylinder, and a cavity is formed inside the movable mold;

[0007] A buffer assembly includes a movable seat slidably mounted on the outer surface of a guide rod via a connecting block, wherein movable blocks are slidably mounted at the top and bottom inside the movable seat.

[0008] As a further improvement to the above solution, a piston rod is fixedly connected to the output end of the hydraulic cylinder, and a movable mold is fixedly installed on the outer surface of the piston rod.

[0009] The above technical solution enables the hydraulic cylinder to effectively drive the movable mold to perform mold closing and opening actions, ensuring the power supply for the movement of the movable mold during the die casting process.

[0010] As a further improvement to the above solution, a second fixing seat is fixedly installed on the outer surface of the movable mold, and the second fixing seat corresponds to the first fixing seat.

[0011] The above technical solutions help improve the positioning accuracy when the fixed mold and the movable mold are closed, so that the cavity and the core can fit together more precisely, thereby improving the quality and dimensional accuracy of die-cast products.

[0012] As a further improvement to the above solution, a movable seat is fixedly installed on the outer surface of the piston rod, and a connecting block is fixedly installed on the top and bottom of the movable seat. The connecting block is slidably installed on the outer surface of the guide rod.

[0013] The above technical solution enables the movable seat to move smoothly along the guide rod as the movable mold driven by the piston rod moves, while also ensuring the guiding nature of the movable mold's movement.

[0014] As a further improvement to the above solution, the movable seat has an embedded groove inside, and movable blocks are slidably installed at the top and bottom of the embedded groove. The movable blocks are fixedly connected to each other by a damper.

[0015] Through the above technical solution, during the mold opening process, the damper can use its own damping characteristics to limit the relative movement of the moving block, thereby effectively buffering the mold opening speed of the moving mold, avoiding impact or vibration caused by excessive speed during mold opening, and protecting the moving mold and the entire equipment structure.

[0016] As a further improvement to the above solution, a first connecting rod is rotatably mounted on one side inside the movable block, and the side of the first connecting rod away from the movable block is rotatably mounted inside the first fixed seat.

[0017] Through the above technical solution, this connection method provides additional support and limits for the movement of the movable mold during mold closing and opening, making the movable mold more stable during movement, which helps to improve the stability of the die casting process and the quality of the die casting products.

[0018] As a further improvement to the above solution, a second connecting rod is rotatably mounted inside the movable block on the side away from the first connecting rod, and the side of the second connecting rod away from the movable block is rotatably mounted inside the second fixed seat.

[0019] The above technical solutions further enhance the stability of the movable mold during mold closing and opening, ensuring that the cavity and core can accurately fit together when the mold is closed, and that the movable mold can smoothly separate when the mold is opened.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model provides support for the entire structure through the first fixed seat, guide rod guides the movable mold to close accurately, the core of the fixed mold and the cavity of the movable mold cooperate to form the shape of the casting, and the injection port ensures the smooth progress of the die casting process, driving the mold closing and injection molding process of the fixed mold and the movable mold in the die casting process, thereby achieving the effect of providing a stable die casting space and plastic injection channel for automotive battery end plate castings.

[0022] This invention uses a movable seat that moves with the movable mold, a damper that limits the relative movement of the movable block to buffer the speed of the movable mold, and a first connecting rod and a second connecting rod to maintain the stability of the movable mold's movement. This results in a stable and buffered movement of the movable mold during the mold opening process, thereby preventing the movable mold from experiencing impact or vibration due to excessive speed during mold opening. At the same time, it ensures the stability of the entire mold opening process to prepare for the next die-casting cycle. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example:

[0032] Please combine Figure 1-5 This embodiment of a high-efficiency die-casting equipment for automotive battery end plate castings includes a fixing component 1. The fixing component 1 includes a mounting plate 101. First fixing seats 102 are fixedly installed on the top and bottom of the outer surface of the mounting plate 101. Guide rods 103 are fixedly installed at the four corners of the outer surface of the mounting plate 101. A fixing mold 104 is fixedly installed on the side of the guide rod 103 away from the mounting plate 101. A core 105 is fixedly installed at the center of the outer surface of the fixing mold 104. An injection port 106 is opened inside the core 105. The equipment also includes:

[0033] Die-casting assembly 2 includes a hydraulic cylinder 201 fixedly installed on the outer surface of mounting plate 101. The output end of the hydraulic cylinder 201 is fixedly connected to a movable mold 203. The movable mold 203 has a cavity 204 inside.

[0034] The buffer assembly 3 includes a movable seat 301 that is slidably mounted on the outer surface of the guide rod 103 via a connecting block 302, and movable blocks 304 that are slidably mounted on the top and bottom inside the movable seat 301.

[0035] A piston rod 202 is fixedly connected to the output end of the hydraulic cylinder 201, and a movable mold 203 is fixedly installed on the outer surface of the piston rod 202.

[0036] A second fixing seat 205 is fixedly installed on the outer surface of the movable mold 203, and the second fixing seat 205 corresponds to the first fixing seat 102.

[0037] When the hydraulic cylinder 201 is working, the piston rod 202 pushes the movable mold 203 to move along the guide rod 103 toward the fixed mold 104, so that the cavity 204 and the core 105 are closed.

[0038] A movable seat 301 is fixedly installed on the outer surface of the piston rod 202. A connecting block 302 is fixedly installed on the top and bottom of the movable seat 301. The connecting block 302 is slidably installed on the outer surface of the guide rod 103.

[0039] The movable base 301 has an embedded groove 303 inside, and movable blocks 304 are slidably installed at the top and bottom inside the embedded groove 303. The movable blocks 304 are fixedly connected to each other by a damper 305.

[0040] A first connecting rod 306 is rotatably mounted on one side inside the movable block 304, and the side of the first connecting rod 306 away from the movable block 304 is rotatably mounted inside the first fixed seat 102.

[0041] The second connecting rod 307 is rotatably mounted inside the movable block 304 on the side away from the first connecting rod 306, and the second connecting rod 307 is rotatably mounted inside the second fixed seat 205 on the side away from the movable block 304.

[0042] Due to the damping effect of the damper 305, the relative movement between the movable blocks 304 is restricted, thereby slowing down the movement speed of the movable mold 203 in the initial stage of mold opening, avoiding the impact or vibration that may be caused by excessive mold opening speed, and playing a buffering and protective role for the movable mold 203.

[0043] The implementation principle of a high-efficiency die-casting equipment for automotive battery end plate castings in this application embodiment is as follows: The mounting plate 101 in the fixed assembly 1 is the basic mounting component of the entire equipment. The top and bottom of its outer surface are equipped with first fixed seats 102. The guide rods 103 installed at the four corners play a guiding role. A fixed mold 104 is fixedly installed on the side of the guide rod 103 away from the mounting plate 101. The core 105 in the center of the fixed mold 104 and the injection port 106 inside the core 105 provide the shape basis and plastic injection channel for die casting.

[0044] In the die-casting assembly 2, the hydraulic cylinder 201 serves as a power source, and its output piston rod 202 is connected to the movable mold 203. The cavity 204 inside the movable mold 203 corresponds to the core 105 of the fixed mold 104. When the hydraulic cylinder 201 works, the piston rod 202 pushes the movable mold 203 to move along the guide rod 103 toward the fixed mold 104, so that the cavity 204 and the core 105 are closed. Then, plastic material is injected through the injection port 106 of the fixed mold 104, and the automotive battery end plate casting is die-cast in the space formed by the cavity 204 and the core 105.

[0045] When the die-casting process ends and the mold closing state needs to be cancelled, the movable seat 301, fixed to the outer surface of the piston rod 202, is slidably mounted on the guide rod 103 via its top and bottom connecting blocks 302. When the movable mold 203 begins to move during the mold opening process, the movable seat 301 also moves accordingly. The movable blocks 304, slidably mounted at the top and bottom, are connected in the embedded groove 303 inside the movable seat 301 via a damper 305. At this time, due to the damping effect of the damper 305, the relative movement between the movable blocks 304 is restricted, thereby slowing down the... The moving speed of the movable mold 203 in the initial stage of mold opening avoids the impact or vibration that may be caused by excessive mold opening speed, and plays a buffering and protective role for the movable mold 203. The first connecting rod 306, which is rotatably installed on one side of the movable block 304, is connected to the inside of the first fixed seat 102, and the second connecting rod 307 on the other side is connected to the inside of the second fixed seat 205. This connection structure helps to maintain the stability of the movement of the movable mold 203 during the mold opening process, ensuring that the entire mold opening process proceeds smoothly and preparing for the next die casting cycle.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
