Description

Technical Field

[0001] The utility model relates to the technical field of casting machines, in particular to a quick connection mechanism for a die-casting mold ejector plate. Background Art

[0002] The die-casting mold top plate is an important part of the die-casting mold, which is used to support the mold and ensure the stability and precision of the mold during the die-casting process. The top plate is usually made of high-strength alloy material with good wear resistance and corrosion resistance;

[0003] The traditional connection device between the ejector plate of the die-casting mold and the die-casting machine has the following problems: the connection device between the ejector plate of the die-casting mold and the die-casting machine is usually fastened by threads, which is restricted by installation space limitations, takes a long time to fasten, and has certain safety hazards, and is prone to breakage during use.

[0004] Therefore, we propose a quick connection mechanism for a die casting mold ejector plate to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a die-casting mold ejector plate quick connection mechanism to solve the problem raised by the above background technology that the connection device between the die-casting mold ejector plate and the die-casting machine in the current market takes a long time to tighten and there are safety hazards.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick connection mechanism for a die-casting mold ejector plate, comprising a ejector plate; the ejector plate is movably connected to an upper draw plate; a plurality of through holes are provided on the upper draw plate, including offset slots and through slots; the offset slots are teardrop-shaped slots; the diameter of the left end of the offset slot is smaller than the diameter of the right end.

[0007] By adopting the above technical solution, the relative positions of the upper draw plate and the dislocation slots can be changed by horizontally drawing the upper draw plate on the top plate and dislocating the dislocation slots up and down.

[0008] As a preferred technical solution of the utility model, a return link is arranged inside the dislocation slot; the diameter of the large end of the return link is the same as the diameter of the right end of the dislocation slot; the return link is movably installed in the dislocation slot.

[0009] By adopting the above technical solution, the return connecting rod can be controlled to engage with the two ends of the offset slot while the upper draw plate is drawn horizontally on the top plate. When the upper draw plate moves horizontally to the left, the return connecting rod tightens the die-casting mold top rod plate and the die-casting machine.

[0010] As a preferred technical solution of the utility model, four offset slots are provided on the upper drawer plate and their opening positions are symmetrical about the center of the upper drawer plate; six through slots are provided on the upper drawer plate.

[0011] The above technical solution can make the connection more stable and improve the safety performance by adopting multiple card slots.

[0012] As a preferred technical solution of the utility model, the offset slots and the through slots both penetrate the upper drawer plate and the top plate.

[0013] The above technical solution can be used to facilitate fixation through the through holes that are located relatively between them.

[0014] As a preferred technical solution of the utility model, a connecting pipe is arranged inside the through slot; the connecting pipe is movably connected to the through slot.

[0015] The above technical solution can be used to connect the upper pumping plate and the top plate through the connecting pipe.

[0016] As a preferred technical solution of the present utility model, rounded corners are added at the joints of the return connecting rod.

[0017] The above technical solution can reduce the risk of breakage to the greatest extent by adding rounded corners.

[0018] As a preferred technical solution of the utility model, the top plate and the upper draw plate are connected by a fixing piece; the fixing piece and the top plate and the upper draw plate are all detachably connected.

[0019] The above technical solution can provide fixation between the upper drawer plate and the top plate through the fixing piece when they are engaged.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model is provided with a dislocation slot and a return connecting rod. By lateral translation of the upper draw plate on the top plate, the end of the dislocation slot with a smaller size is engaged with the top of the return connecting rod, thereby completing the fixation between the die-casting mold ejector plate and the die-casting machine. When disassembling, the upper draw plate can be moved to the other end on the top plate. Thus, the new connection device does not require threaded connection, and is fastened by a matching buckle device, which is extremely simple to operate.

[0022] 2. The utility model is provided with rounded corners, and the risk of breakage is minimized by adding rounded corners at the return link, thereby increasing the strength of the return link, improving safety performance, and reducing safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
