DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-11 As shown, the utility model discloses a forming die for a computer stand, comprising:

[0034] The upper mold 2 includes an upper mold base 21 and an upper mold plate 22. The upper mold base 21 is provided with an injection port 211. The upper portion of the upper mold plate 22 is provided with a flow channel 221 communicating with the injection port 211, and the lower portion of the upper mold plate 22 is provided with an upper mold cavity (not shown) for molding.

[0035] The lower mold 3 includes a lower mold plate 32, a lower mold bottom plate 31, a push plate 33 and a push rod positioning plate 34. A punch 321 matching the upper mold cavity is provided above the lower mold plate 32;

[0036] The upper mold plate 22 is slidably connected to the upper mold base plate 21 through a limiting mechanism;

[0037] The punch 321 is formed by the contoured portion 524 of the ejection assembly 5 and the protruding portion 322 of the lower template 32, and the punch cooperates with the upper model cavity to form an injection cavity. The contoured portion 524 corresponds to the thin-rib deep cavity structure 11 of the computer stand 1. The formed computer stand 1 is ejected in sections through the ejection assembly 5.

[0038] In order to prevent the upper template 22 from slipping, a limiting mechanism is set on the upper mold base plate 21. The limiting mechanism can adopt the following structure, including a limiting screw 4, which passes through the upper template 22 and is threadedly connected to the upper mold base plate 21, and the limiting screw 4 has an abutment portion 41 for limiting the upper template 22 from slipping.

[0039] A compression spring 23 is provided between the upper mold base 21 and the upper mold plate 22. The compression spring 23 is sleeved on the outside of the limit screw 4. The lower mold 3 also has a through hole 35 for accommodating the limit screw 4. When the upper mold 2 and the lower mold 3 are separated, that is, when the molds are opened, the upper mold base 21 moves upward, and the compression spring 23 applies a downward force to the upper mold plate 22. The upper mold plate 22 slides downward along the limit screw 4, disengaging from the upper mold base 21 and forming a cavity with the upper mold base 21. Waste material in the runner 221 can be removed from this cavity.

[0040] In order to realize the segmented ejection action of the computer stand 1 , two groups of ejection components 5 are provided, including a first ejection mechanism 51 and a second ejection mechanism 52 . Both the first ejection mechanism 51 and the second ejection mechanism 52 are connected to the ejector positioning plate 34 .

[0041] The first ejection mechanism 51 includes a plurality of ejector pins 511, with fixed ends 512 of the ejector pins 511 disposed between the push plate 33 and the ejector pin positioning plate 34. In this embodiment, the ejector pins 511 are located at the edges and the thickest center of the computer stand 1. When the push plate 33 moves upward, it first lifts the edges and the thickest center of the computer stand 1.

[0042] The second ejection mechanism 52 includes a push rod 521, a push rod spring 522, and a connecting rod 523. The push rod 521 is slidably connected to the lower mold base plate 31 via a support block 525. The push rod spring 522 is sleeved on the outside of the push rod 521 and is located between the support block 525 and the push plate 33. The connecting rod 523 is located above the push rod 521 and passes through the push rod positioning plate 34. The contoured portion 524 is connected to the top of the connecting rod 523. When the push plate 33 moves upward, it drives the push rod positioning plate 34 with it. At this time, the push rod spring 522 causes the push rod 521 to move upward, driving the connecting rod 523 and the contoured portion 524 upward, ejecting the thin-ribbed deep cavity structure 11 of the computer stand 1. Because the push rod spring 522 is provided at the bottom of the second ejection mechanism 52, the force acting on the thin-ribbed deep cavity structure 11 of the computer stand 1 is flexible, allowing the computer stand 1 to be ejected slowly, avoiding damage caused by sudden force.

[0043] In addition, a positioning protective sleeve 526 is further provided on the outside of the connecting rod 523, and the positioning protective sleeve 526 is connected to the top rod positioning plate 34. The setting of the positioning protective sleeve 526 can prevent the connecting rod 523 from rotating or deviating, causing the contoured portion 524 to fall off and cause it to get stuck.

[0044] In order to improve the positioning accuracy of the upper mold 2 and the lower mold 3, the upper mold 2 also includes a guide column 24, which is slidably connected to the guide sleeve 36 of the lower mold plate 32. When the upper mold 2 and the lower mold 3 are docked, the guide column 24 is first inserted into the guide sleeve 36 to improve the docking accuracy.

[0045] The working method of the present invention is as follows: the upper mold 2 moves downward and docks with the lower mold 3, the punch 321 docks with the upper model cavity, the injection molding material is injected into the injection port 211, and enters the injection molding cavity through the runner 221; the injection molding material solidifies; after solidification, the upper mold 2 moves upward, and the compression spring 23 applies a downward force to the upper template 22, and the upper template 22 slides downward along the limit screw 4, disengages from the upper mold bottom plate 21, and the operator or robot takes out the waste material; at this time, the push plate 33 moves upward, driving the push rod positioning plate 34 to move together, first lifting the edge of the computer bracket 1 and the center position with larger thickness, and at the same time, the push rod spring 522 applies a flexible force for upward movement to the push rod 521. As the edge and the center position with larger thickness of the computer bracket 1 are lifted, the connection strength between the thin rib deep cavity of the computer bracket 1 and the punch 321 will decrease, and the thin rib deep cavity structure 11 will be slowly pushed out by the profiling part 524.

[0046] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
