Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, and in particular to an aluminum plate die-casting mold that is easy to demold. Background Technology

[0002] In the production of aluminum sheets, die casting is a commonly used processing method, and the die casting mold is a key process device in die casting production. However, after die casting is completed, existing aluminum sheet die casting molds are generally equipped with ejector pins to facilitate the demolding of the aluminum sheet. The ejector pins are driven by a drive mechanism to push the aluminum sheet out of the die casting mold cavity.

[0003] However, because the contact area between the traditional ejector pin and the aluminum plate is small, when the ejector pin is pushed towards the aluminum plate by the drive mechanism, it is easy to cause local damage to the aluminum plate, resulting in a decrease in the production quality of the aluminum plate. Utility Model Content

[0004] This utility model discloses an aluminum plate die-casting mold that facilitates demolding, mainly solving the problem that the traditional ejector pin has a small contact area, which easily leads to local damage to the aluminum plate when ejecting it.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides an aluminum plate die-casting mold that is easy to demold, including a fixed mold and a moving mold. The fixed mold is provided with an injection pipe, and the moving mold is provided with an ejection mechanism.

[0007] The fixed mold includes a fixed template, and a fixed mold core is provided on the fixed template;

[0008] The moving mold includes a moving mold base plate, a moving mold plate is provided on the moving mold base plate, a moving mold core is provided on the moving mold plate, a mold cavity is formed between the fixed mold core and the moving mold core, the injection pipe is connected to the mold cavity, a punch is formed on the upper surface of the moving mold core, and a plurality of spaced cavities are provided in the punch;

[0009] The ejection mechanism includes an ejection block, an upper drive plate, and a lower drive plate, which are respectively disposed in the cavity. The surface of the ejection block is adapted to the surface of the punch. The bottom of the ejection block is provided with a plurality of ejection rods. One end of the ejection rod is mounted on the ejection block, and the other end passes through the upper drive plate and is clamped between the upper drive plate and the lower drive plate. The lower drive plate is fixed on the upper drive plate.

[0010] In one embodiment, limiting grooves are provided on the left and right sides of the cavity, and limiting blocks that match the limiting grooves are provided on the left and right sides of the ejector block, with the surface of the limiting block being adapted to the surface of the punch.

[0011] In one embodiment, the moving mold core has a first through hole corresponding to the position of the ejector rod, and the ejector rod passes through the first through hole.

[0012] In one embodiment, the upper drive plate has a second through hole at the position corresponding to the ejector rod, and the ejector rod passes through the second through hole.

[0013] In one embodiment, a limiting rod is provided at the end of the ejector rod away from the ejector block, and a clearance groove is provided on the upper drive plate at the position corresponding to the second through hole. The limiting rod is located in the clearance groove, so that the height of the limiting rod is lower than the clearance groove.

[0014] In one embodiment, side connecting plates are provided between the left and right sides of the moving mold base plate and the moving mold template, so that there is a movable space between the moving mold template and the moving mold base plate, and the upper drive plate and the lower drive plate can move up and down in the movable space.

[0015] In one embodiment, a plurality of support columns are provided between the moving mold base plate and the moving mold template. One end of each support column is supported on the moving mold template, and the other end passes through the upper drive plate and the lower drive plate in sequence and is supported on the moving mold base plate.

[0016] The advantages or beneficial effects of the above technical solution include at least the following: Liquid aluminum is injected into the mold cavity through an injection pipe and squeezed inward by the hydraulic cylinder of the die-casting machine to fill the mold cavity. After the liquid aluminum cools and solidifies to form an aluminum plate, the moving mold can be moved away from the fixed mold. When removing the aluminum plate, the upper and lower drive plates of the ejection mechanism can be pushed by the die-casting machine to drive the ejector rod, which in turn drives the ejector block. This allows the aluminum plate to separate from the moving mold core of the moving mold and be removed. The ejection of the aluminum plate by the ejector block increases the contact area with the aluminum plate, thereby preventing the aluminum plate from having an insufficient stress area, avoiding localized damage, protecting the aluminum plate, and improving production quality.

[0037] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0038] See Figures 1 to 7 The present invention provides an aluminum plate die casting mold that is easy to demold, including a fixed mold 1 and a moving mold 2. The fixed mold 1 is provided with an injection pipe 3, and the moving mold 2 is provided with an ejection mechanism 4.

[0039] The fixed mold 1 includes a fixed template 11, on which a fixed mold core 12 is provided;

[0040] The moving mold 2 includes a moving mold base plate 21, a moving mold plate 22 is provided on the moving mold base plate 21, a moving mold core 23 is provided on the moving mold plate 22, a mold cavity is formed between the fixed mold core 12 and the moving mold core 23, the injection pipe 3 is connected to the mold cavity, a punch 231 is formed on the upper surface of the moving mold core 23, and a plurality of spaced cavities 232 are provided in the punch 231;

[0041] The ejection mechanism 4 includes an ejection block 41, an upper drive plate 43, and a lower drive plate 44, all disposed in the cavity 232. The surface of the ejection block 41 is adapted to the surface of the punch 231. Multiple ejection rods 42 are disposed at the bottom of the ejection block 41. One end of each ejection rod 42 is mounted on the ejection block 41, and the other end passes through the upper drive plate 43 and is clamped between the upper drive plate 43 and the lower drive plate 44. The lower drive plate 44 is fixed to the upper drive plate 43. The adaptation between the ejection block 41 and the surface of the punch 231 ensures that the surfaces of the ejection block 41 and the punch 231 are aligned with the corresponding surfaces of the aluminum plate. A core-pulling mechanism can also be provided on the moving mold 2. Since this core-pulling mechanism is existing technology in the field, its structure and principle will not be described in detail here.

[0042] Using the above structure, liquid aluminum is injected into the mold cavity through the injection pipe 3 and squeezed inward by the hydraulic cylinder of the die-casting machine to fill the mold cavity. After the liquid aluminum cools and solidifies to form an aluminum plate, the moving mold 2 can be moved away from the fixed mold 1. When the aluminum plate is removed, the upper drive plate 43 and the lower drive plate 44 of the ejection mechanism 4 can be pushed by the die-casting machine to drive the ejector rod 42. The ejector rod 42 drives the ejection block 41, which separates the aluminum plate from the moving mold core 23 of the moving mold 2, and the aluminum plate can be removed. The ejection of the aluminum plate by the ejection block 41 increases the contact area with the aluminum plate, thereby preventing the aluminum plate from having too small a force area and avoiding local damage to the aluminum plate, thus protecting the aluminum plate and improving production quality.

[0043] In one embodiment, see Figures 4 to 7 Limiting grooves 234 are provided on the left and right sides of the cavity 232, and limiting blocks 411 matching the limiting grooves 234 are provided on the left and right sides of the ejector block 41. The surface of the limiting block 411 is adapted to the surface of the punch 231. In practical applications, the cooperation of the limiting grooves 234 and the limiting blocks 411 can restrict the position of the ejector block 41 embedded in the cavity 232, so as to ensure that the upper surface of the ejector block 41 and the surface of the punch 231 are always on the same plane, thus avoiding affecting the subsequent production of the aluminum plate.

[0044] The moving mold core 23 has a first through hole 233 through which the ejector rod 42 passes. In practical applications, the first through hole 233 facilitates the ejector rod 42 passing through the moving mold core 23.

[0045] The upper drive plate 43 has a second through hole 431 corresponding to the position of the ejector rod 42, through which the ejector rod 42 passes. In practical applications, the second through hole 431 facilitates the ejector rod 42 to pass through the upper drive plate 43.

[0046] A limiting rod 421 is provided at the end of the ejector rod 42 away from the ejector block 41. A clearance groove 432 is provided on the upper drive plate 43 corresponding to the position of the second through hole 431. The limiting rod 421 is located in the clearance groove 432, so that the height of the limiting rod 421 is lower than that of the clearance groove 432. Preferably, the height of the limiting rod 421 is the same as the depth of the clearance groove 432. In practical applications, the cooperation between the limiting rod 421 and the clearance groove 432 facilitates the upper drive plate 43 in pulling the ejector rod 42.

[0047] In one embodiment, see Figure 1 and Figure 2Side connecting plates 24 are provided between the left and right sides of the moving mold base plate 21 and the moving mold plate 22, creating a movable space between the moving mold plate 22 and the moving mold base plate 21. The upper drive plate 43 and the lower drive plate 44 can move up and down within this movable space. In practical applications, the movable space formed between the side connecting plates 24 and the moving mold base plate 21 provides space for the upper drive plate 43 and the lower drive plate 44 to move up and down.

[0048] Multiple support columns 25 are provided between the moving mold base plate 21 and the moving mold plate 22. One end of each support column 25 is supported on the moving mold plate 22, and the other end passes through the upper drive plate 43 and the lower drive plate 44 in sequence and is supported on the moving mold base plate 21. In practical applications, the support columns 25 provide good support for the moving mold plate 22.
