Description

Technical Field

[0001] The invention relates to the technical field of demoulding machines, in particular to an environmentally friendly demoulding machine for lightweight die castings. Background Art

[0002] In the production process of die-castings, release agents are usually used to reduce the friction coefficient between the mold and the die-casting, making the demolding process smoother and preventing defects such as adhesion and strain on the die-casting during the demolding process. For some die-castings that are prone to adhesion to the mold, the use of release agents can significantly improve the demolding effect.

[0003] When the demoulding speed is too fast, the die-casting may be deformed due to excessive external force. This deformation not only affects the appearance quality of the die-casting, but also reduces its mechanical properties and functionality. Too fast a demoulding speed will increase the adhesion between the mold and the casting, making demoulding difficult, which will not only prolong the production cycle, but may also damage the mold or casting. For this reason, we propose an environmentally friendly demoulding machine for lightweight die-castings. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-9 The present invention provides a technical solution: an environmentally friendly demoulding machine for lightweight die castings, comprising a demoulding machine body 1, a demoulding motor is arranged inside the demoulding machine body 1, a demoulding plate 11 is fixedly connected above the demoulding machine body 1, and a demoulding frame 12 is fixedly connected above the demoulding plate 11;

[0029] The clamping mechanism 2 is fixedly connected with a protective shell 21 above the demoulding disc 11. The clamping mechanism 2 is located inside the protective shell 21. The clamping mechanism 2 can demould the die casting;

[0030] The adjusting mechanism 3 is located inside the demoulding plate 11, and the adjusting mechanism 3 can adjust the speed of the demoulding motor when the die casting is clamped by the clamping mechanism 2;

[0031] When the present invention is in use, the die-casting is placed above the demolding plate 11, the die-casting presses the limit piece 5, and the clamping mechanism 2 clamps the die-casting through the clamping arm 24. At the same time, the clamping arm 24 adjusts the power of the demolding motor through the adjustment mechanism 3. The demolding motor is not shown in the figure. The die-casting is demolded in cooperation with the nozzle 61 above the demolding frame 12. The demolding motor adjusts the demolding speed of the demolding machine body 1 according to the shape and size of the die-casting to avoid damage to the die-casting or the mold.

[0032] The clamping mechanism 2 includes a plurality of fixed rods 22 fixedly connected to the upper end of the demoulding disc 11, each fixed rod 22 having an outer wall fixedly connected to a torsion spring 23, an end of the torsion spring 23 away from the fixed rod 22 being fixedly connected to a clamping arm 24, the clamping arm 24 is located at the periphery of the fixed rod 22 and is rotatably connected to the fixed rod 22, a limiting member 5 capable of limiting the clamping arm 24 is provided below the clamping arm 24, the limiting member 5 includes a limiting groove 51 provided at the upper end of the clamping arm 24, a rotating groove 52 is provided at the upper end of the demoulding disc 11, a rotating rod 53 is fixedly connected to the inner wall of the rotating groove 52, a rotating plate 54 is rotatably connected to the periphery of the rotating rod 53, a pressing block 55 is fixedly connected to one end of the rotating plate 54 close to the center of the demoulding disc 11, a limiting rod 56 is fixedly connected to one end of the rotating plate 54 away from the pressing block 55, a limiting block 57 is fixedly connected to one end of the limiting rod 56 away from the rotating plate 54, and the limiting block 57 is located inside the limiting groove 51 and is clamped with the limiting groove 51;

[0033] When demolding the die-casting, the die-casting is placed on the demolding plate 11, and the die-casting presses the pressing block 55 downward, and the pressing block 55 drives the rotating plate 54 to rotate around the rotating rod 53. At this time, the end of the rotating plate 54 away from the pressing block 55 is tilted upward, and at the same time, the limiting rod 56 fixedly connected to the rotating plate 54 moves upward, and the limiting rod 56 drives the limiting block 57 to move upward. At this time, the limiting block 57 slides out of the limiting groove 51, and the limiting block 57 is no longer engaged with the limiting groove 51. At this time, the clamping arm 24 can rotate and clamp the die-casting. The clamping arm 24 clamps the die-casting to limit the movement and shaking of the die-casting. The clamping mechanism 2 can ensure the stability of the position and posture of the die-casting during the demolding process, prevent inaccurate demolding due to shaking or offset, and help maintain the dimensional accuracy and shape integrity of the die-casting, thereby meeting the strict requirements of product design.

[0034] When the clamping arm 24 is disengaged from the clamping block, the torsion spring 23 located inside the clamping arm 24 drives the clamping arm 24 to rotate around the fixing rod 22. At this time, the clamping arm 24 can clamp the die-casting when rotating around the fixing rod 22, thereby reducing the impact and friction of the die-casting during the demolding process, thereby reducing the risk of damage to the die-casting and the mold.

[0035] A clamping member 4 capable of clamping the die casting is provided at one end of the clamping arm 24 near the center of the demoulding disc 11. The clamping member 4 includes a movable rod 41 fixedly connected to one end of the clamping arm 24 near the center of the demoulding disc 11. A movable plate 42 is rotatably connected to the outer periphery of the movable rod 41. The movable plate 42 is arc-shaped at one end near the center of the demoulding disc 11.

[0036] When the clamping arm 24 rotates around the fixed rod 22, the movable plate 42 located at the clamping ratio near the central end of the demolding disk 11 rotates accordingly. At this time, the movable plate 42 abuts against the die-casting and clamps the die-casting. For die-castings of different sizes, when the clamping arm 24 moves toward the die-casting, the movable plate 42 rotates around the movable rod 41. Multiple movable plates 42 can be adjusted to adapt to the size of the die-casting. The clamping parts 4 of different sizes can be quickly adjusted to adapt to die-castings of different specifications, reducing the time and downtime required for replacing the fixture, thereby improving the overall production efficiency.

[0037] The limit block 57 is made of elastic plastic and is slidably connected in the limit groove 51. After the die-casting is taken out, the pressing block 55 is lifted up and reset. At this time, the pressing block 55 drives the rotating plate 54 to rotate in the opposite direction around the rotating rod 53, and the limit rod 56 at the end of the rotating plate 54 moves downward. At this time, the limit block 57 at the end of the limit rod 56 moves downward. When the clamping arm 24 is reset, the clamping arm 24 abuts against the limit block 57 and lifts the limit block 57 until the limit block 57 moves into the limit groove 51. Since the limit block 57 is elastic, the limit block 57 can slide into the limit groove 51, which is convenient for demolding the next die-casting.

[0038] The adjustment mechanism 3 includes an adjustment rod 31 fixedly connected to the lower end of the clamping arm 24, an adjustment slot 32 is provided at the upper end of the demoulding disc 11, the adjustment slot 32 is arc-shaped, a resistance wire 33 is arranged inside the adjustment slot 32, an electrode rod 34 is fixedly connected to the end of the adjustment rod 31 away from the clamping arm 24, the electrode rod 34 is fitted with the resistance wire 33, and the electrode rod 34 and the resistance wire 33 are respectively connected to the demoulding motor circuit;

[0039] For die-castings with larger sizes, due to their larger volume and mass, the contact area between them and the mold also increases accordingly. Therefore, a smaller demolding speed is usually required to smoothly demold them from the mold. When the clamping arm 24 clamps a die-casting with larger sizes, the clamping arm 24 rotates around the fixed rod 22 with a smaller amplitude, and the electrode rod 34 located below the clamping arm 24 moves a smaller distance. Since the electrode rod 34 and the resistance wire 33 are respectively connected to the demolding motor circuit, and the electrode rod 34 is in close contact with the resistance wire 33, the larger the size of the die-casting, the smaller the rotation amplitude of the clamping arm 24, the smaller the moving distance of the electrode rod 34, the greater the resistance flowing through the resistance wire 33, and the smaller the speed of the demolding motor, the more smoothly the die-casting can be demolded. Conversely, the smaller the size of the die-casting, the larger the rotation amplitude of the clamping arm 24, the larger the moving distance of the electrode rod 34, the smaller the resistance flowing through the resistance wire 33, and the greater the speed of the demolding motor. A faster demolding speed helps to improve production efficiency.

[0040] The outer wall of the demoulding frame 12 is slidably connected with a demoulding ring 6, and a plurality of nozzles 61 are arranged on the inner side of the demoulding ring 6. The nozzles 61 are respectively connected with the electrode rod 34 and the resistance wire 33 circuits. When the die-casting is demoulded, the clamping arm 24 can drive the electrode rod 34 to slide in contact with the resistance wire 33. The nozzle 61 and the demoulding motor are in a parallel circuit. The larger the size of the die-casting, the smaller the current flowing through the demoulding motor, so the slower the speed of the demoulding motor. At the same time, the larger the current flowing through the nozzle 61, the greater the jet power can be provided for the nozzle 61, so that the nozzle 61 can jet the surface of the die-casting after demoulding to remove the residual release agent. The jetting method can not only effectively remove the residual release agent on the surface of the die-casting, avoiding quality problems caused by the residual release agent during subsequent processing or coating, but also compared with the traditional water washing method, the method of removing the release agent by jetting can reduce the generation and discharge of wastewater, reduce the impact on the environment, and avoid waste of resources.
