Description

Technical Field

[0001] This utility model relates to the field of die casting mold technology, and more specifically, to a die casting mold that is easy to demold. Background Technology

[0002] Die casting molds are the core tools in the metal die casting process. They are used to press molten metal (such as aluminum, zinc, and magnesium alloys) into the mold cavity at high pressure and high speed. After the metal cools and solidifies, a precision part with the same shape as the cavity is obtained.

[0003] Publication No. (CN219443387U) discloses a die-casting mold for easy demolding, including a lower mold assembly. The lower mold assembly includes an ejector ring, an ejector rod, a guide post, a sliding rod, a push rod, two connecting rods, a spring, a lifting ring, a fixing frame, a lower mold, a mold cavity, a recessed groove, and a limiting hole. The top end of the sliding rod is symmetrically fixedly connected to the lower surface of the ejector ring. This invention uses a spring to push the lifting ring upwards, causing the lifting ring to move upwards along the guide post. The lifting ring, through the fixing frame, drives the ejector rod upwards, and simultaneously, the lifting ring drives the sliding rod upwards. The ejector rod can eject the center of the steering wheel die-casting, and the lifting ring can eject the edge of the steering wheel die-casting. This avoids uneven force on the steering wheel die-casting, preventing deformation. Moreover, during mold opening, automatic ejection and demolding can be achieved under the push of the spring, simplifying the operator's steps and reducing labor intensity.

[0004] However, this type of die-casting mold that facilitates demolding has the following drawbacks: although it can demold the workpiece, some parts inevitably stick to the upper mold during the demolding process after die casting. At this time, the ejection mechanism of the lower mold cannot demold the sticky workpiece, and it is impossible to avoid the workpiece sticking to the upper mold during the rapid demolding process. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a die-casting mold that is easy to demold, so as to solve the problem that the workpiece cannot be prevented from sticking to the upper mold during the process of rapid demolding of the workpiece in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a die-casting mold that facilitates demolding, comprising...

[0007] The upper mold has multiple slidably connected inner walls with a plurality of clamping plates, both ends of which are fixedly connected to connecting blocks. An elastic element is fixedly connected to one end of each connecting block. The upper mold is detachably connected to a lower template, which is fixedly connected to the outside with a gasket. Positioning posts are fixedly connected to the four corners of the lower template.

[0008] The inner wall of the lower mold plate is provided with a second groove, the upper mold plate is fixedly connected with a stop strip, the upper mold plate is provided with a first groove, and the four corners of the upper mold plate are provided with positioning grooves.

[0009] The inner wall of the upper mold is provided with a sliding groove, and a second retaining plate is slidably connected to the inner wall of the upper mold. The outer side of the positioning post is provided with multiple retaining grooves, and the outer side of the positioning post is slidably connected to the inner wall of the positioning groove.

[0010] The outer side of the connecting block is slidably connected to the inner wall of the upper mold, and the outer side of the elastic element is in contact with the inner wall of the upper mold.

[0011] The end of the gasket away from the lower mold plate is in contact with the inner wall of the upper mold, and the outer side of the gasket is engaged with the inner wall of the groove.

[0012] The end of the stop bar away from the upper mold contacts the inner wall of the lower mold plate, and the end of the stop bar away from the upper mold is engaged with the inner wall of the groove two.

[0013] The end of the first clamping plate away from the upper mold is clamped to the inner wall of the clamping groove, and the end of the second clamping plate away from the upper mold is clamped to the inner wall of the clamping groove;

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above scheme, the interaction between the elastic element and the positioning post in the clamping plate causes the upper mold to vibrate when the upper mold and the lower mold plate separate, which in turn causes the workpieces stuck in the upper mold to leave the mold, achieving a rapid demolding effect. This avoids workpiece sticking and improves efficiency. At the same time, when the upper mold and the lower mold plate are combined to prepare for die casting, the cooperation between the gasket and the upper mold achieves a double sealing effect of concave and convex interlocking, preventing internal solution leakage during die casting of the internal workpieces.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a die-casting mold that is easy to demold, including an upper mold 1, a plurality of clamping plates 2 are slidably connected to the inner wall of the upper mold 1, a connecting block 3 is fixedly connected to both ends of the plurality of clamping plates 2, an elastic element 4 is fixedly connected to the adjacent end of the connecting block 3, a lower template 8 is detachably connected to the outside of the upper mold 1, a gasket 11 is fixedly connected to the outside of the lower template 8, and positioning posts 9 are fixedly connected to the four corners of the lower template 8. The outside of the connecting block 3 is slidably connected to the inner wall of the upper mold 1, and the outside of the elastic element 4 is in contact with the inner wall of the upper mold 1.

[0024] When the upper mold 1 and the lower template 8 are detached, the clamping plate 2 and the elastic element 4 will slide outside the positioning post 9. Under the influence of the elastic element 4, the upper mold 1 will vibrate as it leaves the lower template 8, and this vibration will act on the upper mold 1 to detach the workpiece inside it. This achieves rapid demolding of the workpiece. At the same time, the gasket 11 enhances the sealing effect between the upper mold 1 and the lower template 8.

[0025] Example 2: Based on Example 1, in order to conveniently enhance its sealing performance, the inner wall of the lower template 8 is provided with a second groove 14, the outer side of the upper mold 1 is fixedly connected with a baffle 12, the outer side of the upper mold 1 is provided with a first groove 13, the four corners of the upper mold 1 are provided with positioning grooves 6, the end of the gasket 11 away from the lower template 8 is in contact with the inner wall of the upper mold 1, the outer side of the gasket 11 is engaged with the inner wall of the first groove 13, the end of the baffle 12 away from the upper mold 1 is in contact with the inner wall of the lower template 8, and the end of the baffle 12 away from the upper mold 1 is engaged with the inner wall of the second groove 14.

[0026] When the upper mold 1 and the lower mold plate 8 are combined in preparation for die casting, the baffle 12 in the upper mold 1 will be stuck inside the second groove 14, and the gasket 11 outside the lower mold plate 8 will be stuck inside the first groove 13 in the upper mold 1. This forms a double seal, which prevents internal solution leakage due to pressure during die casting and improves its sealing effect.

[0027] Example 3: Based on Example 2, in order to facilitate the movement of the first card plate 2, a sliding groove 5 is provided on the inner wall of the upper mold 1, and a second card plate 7 is slidably connected to the inner wall of the upper mold 1. Multiple slots 10 are provided on the outside of the positioning post 9, and the outside of the positioning post 9 is slidably connected to the inner wall of the positioning groove 6. The end of the first card plate 2 away from the upper mold 1 is engaged with the inner wall of the slot 10, and the end of the second card plate 7 away from the upper mold 1 is engaged with the inner wall of the slot 10.

[0028] When the upper mold 1 is pulled, the first clamping plate 2 and the second clamping plate 7 in the upper mold 1 will slide along the groove 10 in the positioning post 9 under the influence of the elastic element 4 through the connecting block 3. Since the contact surface between the first clamping plate 2 and the second clamping plate 7 and the groove 10 is arc-shaped, and since the lower mold plate 8 is fixed in the table, when the upper mold 1 is pulled to achieve the demolding action, the first clamping plate 2 and the second clamping plate 7 will slide along the groove 10 in the positioning post 9. At the same time, the elastic element 4 will contract after being stretched, so the first clamping plate 2 and the second clamping plate 7 will impact the positioning post 9, causing the upper mold 1 to vibrate. After the workpiece attached to the upper mold 1 is vibrated, it will fall off the inside of the upper mold 1, avoiding the workpiece that has been die-casting from being attached to the upper mold 1 and unable to be demolded. In this way, the workpiece inside is separated from the mold and no longer sticks while the mold is being demolded.

[0029] The working process of this utility model is as follows:

[0030] First, when the upper mold 1 is pulled, the first clamping plate 2 and the second clamping plate 7 in the upper mold 1 will slide along the groove 10 in the positioning post 9 under the influence of the elastic element 4 through the connecting block 3. Since the contact surface between the first clamping plate 2 and the second clamping plate 7 and the groove 10 is arc-shaped, and since the lower mold plate 8 is fixed in the table, when the upper mold 1 is pulled to achieve the demolding action, the first clamping plate 2 and the second clamping plate 7 will slide along the groove 10 in the positioning post 9. At the same time, the elastic element 4 will contract after being stretched, so the first clamping plate 2 and the second clamping plate 7 will impact the positioning post 9, causing the upper mold 1 to vibrate and lift the upper mold plate 8. When the workpiece attached to the upper mold 1 is vibrated, it falls off from the inside of the upper mold 1, preventing the die-cast workpiece from remaining attached to the upper mold 1 and unable to be demolded. This achieves the simultaneous demolding of the mold and the removal of the internal workpiece from the mold, preventing it from sticking together. At the same time, when the upper mold 1 and the lower mold plate 8 are combined in preparation for die casting, the baffle 12 in the upper mold 1 will be stuck inside the second groove 14, and the gasket 11 outside the lower mold plate 8 will be stuck inside the first groove 13 in the upper mold 1. This forms a double seal, preventing internal solution leakage due to pressure during die casting and improving its sealing effect.
