Description

Technical Field

[0001] The utility model relates to the technical field of die-casting machines, in particular to a tail plate of a large die-casting machine. Background Art

[0002] With the rise and development of die-casting integration in recent years, the requirements for die-casting scale, clamping force, etc. of die-casting equipment are getting higher and higher. In the past, the clamping mechanism of die-casting machines was mostly a hinged structure. If large die-casting machines still use this structure, there are many parts and components of this structure, and the cumulative error of assembly and matching will increase, and the later maintenance and repair will be more cumbersome. A two-plate die-casting machine adopts a follow-up locking mechanism. The tail plate is an important component of the dynamic mold locking mechanism. With the demand for large clamping force and high-efficiency die-casting in die-casting integration, a tail plate suitable for large die-casting machines is designed. Summary of the invention

[0003] The utility model proposes a tail plate of a large die-casting machine, comprising a plate body, wherein a columnar pressure chamber for cooperating with a clamping piston is arranged at the center of the plate body, a plurality of rod-penetrating holes are arranged around the columnar pressure chamber, and the rod-penetrating holes are distributed at equal angles around the columnar pressure chamber.

[0004] The utility model is further configured as follows: fixed hanging handles are arranged on both sides of the board body.

[0005] The utility model is further configured as follows: a detachable hanging handle installation position is arranged on the top of the board body.

[0006] The utility model is further configured as follows: an annular limiting boss is provided at the bottom of the columnar pressure chamber.

[0007] The beneficial effects of the utility model are:

[0008] This type of tail plate has a simple structure and is suitable for large die-casting machines. It can improve the concentration of clamping force and thus improve the clamping efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] See also Figure 1-4 The utility model proposes a tail plate of a large die-casting machine, including a plate body 1. A columnar pressure chamber 2 for cooperating with a mold locking piston is arranged in the center of the plate body 1 as a mold locking power. An annular limiting boss 4 is arranged at the bottom of the columnar pressure chamber 2 for limiting the mold locking piston. Four rod-through holes 3 are arranged around the columnar pressure chamber, and the rod-through holes 3 are distributed at equal angles around the columnar pressure chamber, and are specifically located at the four corners of the plate body 1. The rod-through holes 3 are used to penetrate the connecting rod.

[0016] Fixed hangers 5 are provided on both sides of the plate body 1. A detachable hanger installation position 6 is provided on the top of the plate body 1. The detachable hanger installation position 6 is provided with a positioning hole and a threaded hole for installing the hanger during part processing and assembly.

[0017] This type of tail plate has a simple structure and is suitable for large die-casting machines. It can improve the concentration of clamping force and thus improve the clamping efficiency.
