Description

Technical Field

[0001] This utility model relates to the field of die casting technology, specifically a cable head die casting machine equipped with an automatic ejection and demolding mechanism. Background Technology

[0002] As a key connecting component of cable assemblies in the automotive, construction machinery and other fields, the forming accuracy and production efficiency of cable heads directly affect the overall assembly quality and performance of the cable. At present, cable heads are mostly manufactured by die casting process. The die casting machine realizes the deformation and forming of metal parts in the mold cavity, which is the core equipment for the mass production of cable heads. While existing cable head die-casting machines can complete the basic mold closing and die-casting processes, two key problems still exist in actual production, restricting production efficiency and product consistency: After the existing die-casting machine completes the forming of the cable head, it mostly relies on manual demolding or a complex side-push demolding mechanism. Manual demolding is not only labor-intensive and inefficient, but also prone to deformation or surface damage of the cable head due to improper operation. The side-push demolding mechanism has many moving parts, high maintenance costs, and is difficult to adapt to the demolding requirements of different specifications of cable heads. Meanwhile, during the die casting of the cable head, one end of the cable needs to be embedded into the molding cavity and integrally formed with the metal part. This requires that one end of the cable be fixed first during the die casting process, and that the length of the cable extending out of the cable head meets the design requirements. In the existing technology, the fixing and length control of the cable are mostly accomplished by additional auxiliary positioning equipment. The cable position needs to be manually adjusted and fixed before die casting, and the positioning device is removed after die casting. This not only increases the number of process steps and extends the production cycle, but also easily leads to inconsistent cable extension lengths due to manual adjustment errors, affecting the assembly accuracy of subsequent cable components, and even causing product scrap. In summary, existing cable head die-casting machines have significant shortcomings in terms of automated demolding and integrated cable length control, making it difficult to meet the demand for efficient and high-precision cable head production. There is an urgent need for a die-casting device that can automatically eject and demold, and simultaneously complete cable fixing and predetermined length pulling, in order to solve the above-mentioned technical pain points. Utility Model Content

[0003] The purpose of this invention is to provide a cable head die-casting machine with an automatic ejection and demolding mechanism, so as to solve the problems mentioned in the background art, such as low efficiency, easily damaged parts and high maintenance costs due to manual demolding or complex side-push mechanisms, and cumbersome processes, long production cycles and poor precision due to the need for additional auxiliary equipment for cable fixing and length control.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable head die casting machine equipped with an automatic ejection and demolding mechanism, comprising a mounting frame, a rotating movable frame mounted on the upper end of the mounting frame, and a rotating angle hydraulic rod mounted on the outer surface of the middle section of the mounting frame, the upper end of the angle hydraulic rod being rotatably connected to the movable frame, a lower mold base being fixedly disposed inside the lower end of the movable frame, a mold closing hydraulic rod being fixedly mounted on the upper end of the movable frame, and an upper template being fixedly connected to the lower end of the mold closing hydraulic rod, and an upper mold base being fixedly disposed on the lower surface of the upper template, a forming cavity being opened on the outer surface of the opposite side of the upper mold base and the lower mold base, and clearance holes being opened on the outer surfaces of both ends of the upper mold base and the lower mold base; The lower end face of the movable frame is fixedly installed with an ejector hydraulic rod, and the upper end of the ejector hydraulic rod is fixedly connected with an ejector plate, and an ejector rod is fixedly provided on the upper surface of the ejector plate. The outer surface of the movable frame has a through hole, and a locking hydraulic rod is fixedly installed on the upper end of the mounting frame opposite the through hole, and a locking plate is fixedly connected to the upper end of the locking hydraulic rod.

[0005] Preferably, the clearance holes on the outer surfaces of both ends of the upper and lower mold bases are concentrically arranged, and the clearance holes at both ends of the upper and lower mold bases are connected to the molding cavity.

[0006] By adopting the above technical solution, it can be ensured that the cable can pass smoothly through the clearance hole and extend into the molding cavity. At the same time, the concentric structure can ensure that the cable is in the preset position after the mold is closed, avoiding misalignment between the cable and the metal part due to hole offset, and providing precise guidance for the integral molding of the cable head and the cable.

[0007] Preferably, the upper end of the ejector rod penetrates the inner surface of the forming cavity in the lower mold base, and the upper end face of the ejector rod is flush with the inner surface of the forming cavity.

[0008] By adopting the above technical solution, the ejector rod can directly act on the cable head in the molding cavity during demolding, achieving stable ejection. At the same time, the design of the upper end face of the ejector rod being flush with the inner surface of the molding cavity can prevent scratches on the surface of the cable head during demolding, thus ensuring the product molding quality.

[0009] Preferably, the through hole is positioned directly opposite the relief hole, and the end of the through hole facing the relief hole has an arc-shaped chamfer design.

[0010] By adopting the above technical solution, the setting of the relief hole allows the cable to directly enter the exit hole after passing through the relief hole, reducing path deviation. The arc chamfer design can prevent the cable from being scratched by the edge of the hole when passing through it, protecting the integrity of the cable structure and reducing the product scrap rate caused by cable damage.

[0011] Preferably, the locking plate has an arched design with the middle section protruding upwards, and the locking plate is positioned directly opposite the through hole.

[0012] Using the above technical solution, the arched structure with a raised middle section can increase the contact area between the locking plate and the cable, improve the clamping stability, and prevent the cable from shifting during the die casting process. The setting facing the through hole can ensure that the locking plate acts precisely on the through cable, providing a reliable fixed foundation for controlling the extension length of the cable by rotating the movable frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cable head die-casting machine equipped with an automatic ejection and demolding mechanism: 1. An integrated automatic ejection and demolding mechanism is formed by setting an ejector hydraulic rod, an ejector plate, and an ejector rod. After die casting is completed, the ejector hydraulic rod drives the ejector plate to move the ejector rod upward. The upper end of the ejector rod directly acts on the cable head in the molding cavity, which can quickly eject it from the lower mold base. Compared with the manual demolding in the prior art, this mechanism does not require manual intervention, which greatly improves the demolding efficiency. Compared with the side-push demolding mechanism, it has a simple structure, fewer moving parts, and reduced maintenance costs. Moreover, the design that the upper end face of the ejector rod is flush with the inner surface of the molding cavity can avoid scratches or deformation on the surface of the cable head during the ejection process, thus ensuring product quality. 2. By coordinating the locking hydraulic rod, locking plate, through hole, and clearance hole, the cable can be fixed and positioned directly during the die-casting process. One end of the cable passes through the clearance hole into the through hole and extends between the locking plate and the mounting frame. The locking hydraulic rod drives the locking plate to descend, and the arched structure in its middle section can stably press the cable onto the upper surface of the mounting frame, achieving reliable fixation. At the same time, the movable frame can be driven to rotate by the angle hydraulic rod. Combined with the tension after the cable is fixed, the portion of the cable extending beyond the cable head can be precisely pulled out to a predetermined length without the need for additional auxiliary positioning equipment. This design reduces the manual adjustment and disassembly / reassembly of the positioning device, shortens the production cycle, and controls the length through a mechanical structure, avoiding human operation errors, ensuring the consistency of the cable extension length, and improving the accuracy of subsequent assembly.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a cable head die casting machine equipped with an automatic ejection and demolding mechanism.

[0018] Example 1: This example discloses: a mounting frame 1, a rotating movable frame 2 mounted on the upper end of the mounting frame 1, and a rotating angle hydraulic rod 3 mounted on the outer surface of the middle section of the mounting frame 1, with the upper end of the angle hydraulic rod 3 rotatably connected to the movable frame 2. A lower mold base 4 is fixedly installed inside the lower end of the movable frame 2, and a mold closing hydraulic rod 5 is fixedly installed on the upper end of the movable frame 2. An upper template 6 is fixedly connected to the lower end of the mold closing hydraulic rod 5, and an upper mold base 7 is fixedly installed on the lower surface of the upper template 6. A forming cavity 8 is opened on the outer surface of the upper mold base 7 and the lower mold base 4 facing each other, and clearance holes 9 are opened on the outer surfaces of both ends of the upper mold base 7 and the lower mold base 4. The clearance holes 9 on the outer surfaces of both ends of the upper mold base 7 and the lower mold base 4 are concentrically arranged, and the clearance holes 9 on both ends of the upper mold base 7 and the lower mold base 4 are connected to the molding cavity 8. The movable frame 2 is installed on the upper end of the mounting frame 1 through a rotating structure. The lower mold base 4 is fixed inside the lower end. When the mold closing hydraulic rod 5 fixed on the upper end of the movable frame 2 is activated, the mold closing hydraulic rod 5 extends downward and pushes the upper template 6 fixedly connected to its lower end to move down synchronously. This causes the upper mold base 7 fixed on the lower surface of the upper template 6 to move closer to the lower mold base 4 until the upper mold base 7 and the lower mold base 4 are tightly fitted together. The forming cavities 8 opened on the opposite sides of the two close, forming a closed cavity for the cable head die casting. After the metal part is formed into a cable head in the forming cavity 8, the hydraulic rod 5 is controlled to retract, which drives the upper mold plate 6 and the upper mold base 7 to return to their original position and separate from the lower mold base 4, thus completing the mold opening action and exposing the cable head in the forming cavity 8.

[0019] Example 2: This example discloses the following based on Example 1: A push-out hydraulic rod 10 is fixedly installed on the lower end face of the movable frame 2, and a push-out plate 11 is fixedly connected to the upper end of the push-out hydraulic rod 10, and a push-out rod 12 is fixedly provided on the upper surface of the push-out plate 11. The upper end of the ejector rod 12 penetrates the inner surface of the forming cavity 8 inside the lower mold base 4, and the upper end face of the ejector rod 12 is flush with the inner surface of the forming cavity 8. After the mold is opened, the ejector hydraulic rod 10 fixed to the lower end face of the movable frame 2 is activated. The ejector hydraulic rod 10 extends upward and pushes the ejector plate 11 fixedly connected to its upper end. The ejector plate 11 drives the ejector rod 12 fixed on the upper surface to move upward synchronously. Since the upper end of the ejector rod 12 penetrates the inner surface of the forming cavity 8 in the lower mold base 4, the ejector rod 12 will directly act on the pull cable head in the forming cavity 8, and smoothly eject the pull cable head from the forming cavity 8 of the lower mold base 4, realizing automatic demolding without manual intervention.

[0020] Example 3: This example is based on Example 1 and Example 2: The outer surface of the movable frame 2 is provided with a through hole 13, and a locking hydraulic rod 14 is fixedly installed on the upper end of the mounting frame 1 opposite to the through hole 13, and a locking plate 15 is fixedly connected to the upper end of the locking hydraulic rod 14. The through hole 13 is positioned directly opposite the relief hole 9, and the end of the through hole 13 facing the relief hole 9 has an arc-shaped chamfer design. The locking plate 15 has an arched design with the middle section protruding upwards, and the locking plate 15 is set directly opposite the through hole 13; One end of the cable is passed through the clearance holes 9 on the outer surfaces of the upper mold base 7 and the lower mold base 4, and the through holes 13 on the outer surface of the movable frame 2, so that one end of the cable rests on the upper surface of the mounting frame 1. The locking hydraulic rod 14, which is fixed on the upper end of the mounting frame 1 and faces the through holes 13, is activated. The locking hydraulic rod 14 slides downward, and the locking plate 15, which is fixedly connected to its upper end, approaches the cable. The arched structure of the locking plate 15 is used to press the cable tightly against the upper surface of the mounting frame 1, so as to achieve reliable fixation of the cable and avoid the cable displacement during the die casting process, which would cause molding deviation. Activate the angle hydraulic rod 3, which is installed on the outer surface of the middle section of the mounting frame 1 and rotatably connected to the movable frame 2. Adjust the tilt angle of the movable frame 2 by extending or retracting the angle hydraulic rod 3. Since one end of the cable is fixed by the locking plate 15, when the movable frame 2 tilts, it will drive the lower mold base 4 and the upper mold base 7 to rotate synchronously. Utilize the fixed tension of the cable to pull the part of the cable extending out of the molding cavity 8 out to a predetermined length. No manual measurement and adjustment is required, which ensures that the extension length of each cable is consistent and improves the subsequent assembly accuracy.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
