Description

Technical Field

[0001] This utility model belongs to the field of casting demolding, and specifically relates to a rapid casting demolding mechanism. Background Technology

[0002] Casting demolding mechanism is a general term for molds used in compression molding, extrusion molding, injection molding, blow molding, and combination molds. The coordinated changes of the mold punch, die, and auxiliary molding system can produce a series of plastic parts of different shapes and sizes.

[0003] Existing technologies have developed some rapid casting demolding mechanisms. Although they can demold quickly, they are inconvenient for workers to remove the molded parts during use. This is because the distance between the upper and lower molds is too short during demolding, which increases the difficulty for workers to remove the cast parts and makes it impossible to effectively and quickly remove the molded parts.

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] The following is combined with Figures 1 to 7 The following describes the rapid casting demolding mechanism 1000 of this utility model embodiment.

[0036] like Figures 1 to 7 As shown, the rapid casting demolding mechanism 1000 according to an embodiment of the present invention includes a support assembly 1, a lower mold 2, a cooling assembly 3, a first drive assembly 4, an upper mold 5, a second drive assembly 6, and a third drive assembly 7.

[0037] The bracket assembly 1 mainly provides installation support; the lower mold 2 is mounted on the bracket assembly 1; the cooling assembly 3 is connected to the lower mold 2 to cool the molded part inside the lower mold 2; the first drive assembly 4 is mounted on the bracket assembly 1 and extends vertically into the lower mold 2 from below to push the molded part inside the lower mold 2 upward; the upper mold 5 is arranged above the lower mold 2; the second drive assembly 6 is arranged above the upper mold 5 and connected to the upper mold 5 to drive the upper mold 5 to move vertically; and the third drive assembly 7 is mounted on the bracket assembly 1 and connected to the second drive assembly 6 to drive the second drive assembly 6 and the upper mold 5 to move laterally together.

[0038] The working principle of the rapid casting demolding mechanism 1000 of this utility model embodiment is as follows: The material to be cast is placed in the lower mold 2. The third driving component 7 drives the second driving component 6 and the upper mold 5 to move laterally to directly above the lower mold 2 and align with it. Then, the second driving component 6 drives the upper mold 5 to move vertically downward, so that the upper mold 5 and the lower mold 2 are closed, and the material to be cast is formed in the lower mold 2 and the upper mold 5 to form a molded part. Next, the cooling component 3 cools the molded part in the lower mold 2. After cooling, the second driving component 6 drives the upper mold 5 to move vertically upward, so that the upper mold 5 and the lower mold 2 are separated. The third driving component drives the upper mold 5 and the second driving component to move laterally, so that the upper mold 5 and the second driving component 6 are away from the position above the lower mold 2. Finally, the first driving component 4 pushes the molded part in the lower mold 2 upward, so that the molded part is demolded.

[0039] The rapid casting demolding mechanism 1000 of this embodiment of the present invention cools the molded part in the lower mold 2 through the cooling component 3, which is beneficial for demolding. The third driving component 7 drives the second driving component 6 and the upper mold 5 to move laterally, moving the upper mold 5 and the second driving component 6 away from the upper position opposite the lower mold 2, greatly increasing the space above the lower mold 2, which is convenient for workers to remove the molded part. The upper mold 5 and the second driving component 6 do not obstruct workers from removing the molded part, providing operational convenience. The first driving component 4 pushes the molded part upward in the lower mold 2, demolding the part and facilitating its removal by workers, further enhancing operational convenience. In summary, the rapid casting demolding mechanism 1000 of this embodiment of the present invention enables rapid demolding of the molded part in the lower mold 2, allowing workers to quickly remove the molded part and making operation more convenient.

A lower mold 2 is disposed on the upper side of the fixed base plate 102. A first drive assembly 4 is disposed on the base 101. A third drive assembly 7 is disposed on the top of the support frame 103. Thus, the structural layout is reasonable.

[0041] In some embodiments, the third drive assembly 7 includes a motor 701, a lead screw 702, and a slider 703. The motor 701 can be a servo motor 701, which is fixed to one side of the top of the support frame 103. The lead screw 702 is arranged laterally, with one end connected to the motor 701 and the other end rotatably supported on the top of the support frame 103. The slider 703 is threadedly engaged with the lead screw 702 and laterally slides with the top of the support frame 103. The second drive assembly 6 is fixed to the slider 703. When the third drive assembly 7 is working, the motor 701 drives the lead screw 702 to rotate, causing the slider 703 to move along the axial direction of the lead screw 702, that is, the slider 703 moves laterally, thereby causing the second drive assembly 6 and the upper mold 5 to move laterally.

[0050] In some embodiments, the second drive assembly 6 further includes a guide telescopic rod 602, which is disposed between the slider 703 and the upper mold 5. The function of the guide telescopic rod 602 is to prevent the upper mold 5 from shifting when it moves up and down, and in particular to prevent the upper mold 5 from shifting when it is pressed down.

[0051] Specifically, the guide telescopic rod 602 can be an electric actuator, and there can be multiple guide telescopic rods 602. The multiple guides can be distributed symmetrically or asymmetrically on both sides of the upper mold 5.
