Description

Technical Field

[0001] The present invention relates to the technical field of metal die-casting dies, and in particular to a die-casting die for processing a power supply shell. Background Art

[0002] In industrial production, molds are tools used to make molded plastic parts, which mainly achieve the processing of the object's appearance by changing the physical state of the molding material. For example, the Chinese utility model patent with the announcement number CN217196684U provides an automobile die-casting mold with an exhaust structure, including a die-casting frame, a die base is provided inside the die-casting frame, a fixed mold is provided on one side of the die base, a movable mold is movably provided on one side of the die base, and a molded part is connected to one side of the movable mold through a top mold assembly. The interior of the movable mold is provided with an exhaust assembly, and the top mold assembly includes a hydraulic connecting rod, a push plate, a push rod and a spring. The exhaust assembly includes a fixed column, a slide plate and an interpenetrating tube. Under the action of the top mold assembly, this patent enables the push rod to eject the molded part through the elasticity of the spring, forming a demolding effect, and improves the quality of the die-casting of the molded part through the exhaust assembly.

[0003] However, existing molds often use a straight ejection method, whereby ejectors are used to eject the die-cast product upward. This method can easily leave ejector marks on the product, which require subsequent treatment. Furthermore, if the ejector pins are improperly positioned and the temperature difference between the ejected product is large, cracking of the ejected product can occur.

[0004] In view of this, we propose a die-casting mold for processing a power supply housing. Summary of the Invention

The fifth connecting rod 411 is fixedly connected to the telescopic rod 412 at one end away from the cross bar 41, and the outer wall of the inner tube of the telescopic rod 412 is fixedly connected to the toggle ball 413. The top of the middle end of the step plate 31 is fixedly connected to the convex frame 42, and a plurality of vertical No. 1 bar-shaped holes 421 are opened on the surface of the convex frame 42. The inner lower end position of the convex frame 42 is fixedly connected to the No. 1 raised column 422, the No. 1 sliding column 43 and the No. 2 sliding column 44 slide through and are connected to the convex frame 42 at different heights in the vertical direction. The lower outer wall of the No. 1 sliding column 43 and the lower outer wall of the No. 2 sliding column 44 are both sleeved with a No. 1 spring 432, and the No. 1 spring 432 is placed in the convex frame 42; The outer wall of the middle end of the No. 2 sliding column 44 is fixedly connected with the No. 2 extension rod 441, the No. 1 extension rod 431 and the No. 2 extension rod 441 are both slidably connected in multiple No. 1 bar holes 421, and the inner side of the convex frame 42 is slidably connected with a sliding plate 45, and the upper end of the sliding plate 45 is provided with a horizontal hole 451 and a hook hole 452, the horizontal hole 451 coincides with the position of the No. 2 extension rod 441, and the position of the hook hole 452 coincides with the position of the No. 1 extension rod 431, and the lower end of the sliding plate 45 is fixedly connected with a No. 2 raised column 453, and the lower end of the sliding plate 45 is provided with a No. 2 bar hole 455, the No. 1 raised column 422 is slidably connected in the No. 2 bar hole 455, and a No. 2 spring 454 is fixedly connected between the No. 1 raised column 422 and the No. 2 raised column 453.

[0027] It can be seen from this that before the die-cast power supply housing needs to be demoulded, Figure 1-Figure 3 As shown, first, the two side molds 2 are sealed against the bottom mold 122, and then the bottom mold 122 is injection molded through an external input device. At this time, the sliding table 11 is driven downward by the electric slide rail on the inner side of the support frame 1, so that the vertical rod 111 drives the top mold 112 to be pressed down together, and the material in the bottom mold 122 is die-cast; then, after the product is formed, the sliding table 11 drives the top mold 112 to move upward and separate from the product.

[0028] When the top mold 112 is separated from the product, demoulding is required, as follows: The motor drives the No. 1 rotating rod 32 and drives the rotating disk 321 to rotate. The No. 1 rotating rod 32 is at a non-center position of the rotating disk 321, so that the No. 1 rotating rod 32 drives the rotating disk 321 to rotate in an eccentric circle. At this time, the No. 1 connecting rod 322 outside the rotating disk 321 forms a push-pull effect. At the same time, the No. 1 connecting rod 322 also drives the short rod 33 to form a push-pull rotation effect. When the short rod 33 rotates, the No. 3 connecting rod 342 is driven to rotate together through the No. 2 rotating rod 331, and the No. 3 connecting rod 342 will drive the No. 3 connecting rod 342 to rotate during the rotation process. The second connecting rod 341 and the fourth connecting rod 343 rotate together. At this time, the fourth connecting rod 343 drives the support plate 35 and the oblique plate 24 to rotate together. The oblique plate 24 gradually drives the insertion rod 23 and the side mold 2 to rotate upward and lift the product upward for a short distance. At this time, the side mold 2 will initially perform a slight demoulding operation on the product; then, as the oblique plate 24 continues to rotate, the side mold 2 will gradually separate from the product and expand outward. At this time, the two side molds 2 will completely separate from the product, leaving both sides of the product exposed to the outside for easy cooling of the product. When the second lever 41 is lifted up, the lever 413 is in the forward position and the second lever 414 is in the forward position, so that the second lever 413 can be pushed upwards to push the second lever 414 away from the engagement of the lever 412. During the demoulding process, the demoulding force of the product is decomposed into horizontal forces on both sides and vertical forces in the middle through the coordinated action of the No. 1 sliding column 43, the corresponding No. 1 spring 432, and the side mold 2, thereby reducing product damage and improving the yield rate; It should be noted that before the next die-casting, the side mold 2 can be driven back to the sealed position with the bottom mold 122 by the connecting rod assembly 3 for the next die-casting, and when the side mold 2 returns to the bottom mold 122 position, the toggle ball 413 will press down the No. 2 sliding column 44 again, and make the No. 1 sliding column 43 return to the state of being locked by the hook hole 452 again.

[0029] In addition, the telescopic rod 412 is a prior art, mainly comprising an outer tube and an inner tube, wherein the inner tube is slidably placed in the inner cavity of the outer tube; Figure 5 As shown, inner tubes are provided at both ends of the outer tube of the telescopic rod 412, and details thereof will not be repeated.

[0030] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
