Problems solved by technology

[0003] In the existing die-casting technology field, the design form of mold and die-casting machine is basically fixed, and the upper mold and lower mold have a fixed relative position. After one installation, this fixed mold and die-casting machine cannot be separated automatically. When performing special die-casting (such as the mold cavity needs to be preheated before die-casting, and the workpiece needs to be directional solidified with the mold cavity after die-casting), it is necessary to disassemble the mold and perform pre-die-casting or post-die-casting treatment outside the die-casting machine; when die-casting When the product changes, it is necessary to stop the machine to disassemble and replace the mold. This production method is difficult to meet the continuous production needs of various die-casting products, and the production efficiency is low.

Embodiment 1

[0033] Reference figure 1 The embodiment of the die-casting machine of the present invention includes a die-casting machine body 1, a spring clamping positioning mechanism 2 and a chain transfer mechanism 4; the die-casting machine body 1 is provided with a horizontal lower mold sliding beam 1-1, and the upper mold sliding beam 1-1 There are two parallel grooves on the surface. The die casting machine body 1 of this embodiment is transformed by a four-column hydraulic press, and a lower mold sliding beam 1-1 is added to the four-column hydraulic press.

[0034] Reference figure 2 , The spring clamping positioning mechanism 2 is located on the upper surface of the lower mold sliding beam 1-1, the spring clamping positioning mechanism 2 includes a positioning mechanism 2-1 and a clamping mechanism 2-2, a positioning mechanism 2-1 and a clamping mechanism 2- 2 Located on both sides of two parallel grooves.

[0035] Reference image 3 , The positioning mechanism 2-1 includes two long...

Embodiment 2

[0045] The difference between the die-casting machine of this embodiment and the die-casting machine of embodiment 1 is only that: the positioning mechanism 2-1 includes a long roller mounting plate 2-1-1 and a fixed frame 2-1-3; and a movable plate 2-2-2 A short roller mounting plate 2-2-1 is provided on the side close to the groove; the front and rear of the fixed plate 2-2-3 are each provided with a sliding shaft 2-2-6; there is no compression in the spring The distance between the end surface of the upper roller 2-1-2 of the short roller mounting plate 2-2-1 and the end surface of the upper roller 2-1-2 of the long roller mounting plate 2-1-1 is smaller than the width of the mold 3 by 6 mm. The rest is the same as in Example 1.

Embodiment 3

[0047] The difference between the die-casting machine of this embodiment and the die-casting machine of embodiment 1 is only that: the positioning mechanism 2-1 includes three long roller mounting plates 2-1-1 and a fixed frame 2-1-3; and a movable plate 2-2-2 There are 3 short roller mounting plates 2-2-1 on the side close to the groove; 3 sliding shafts 2-2-6 are respectively provided at the front and rear of the fixed plate 2-2-3; there is no compression in the spring The distance between the end surface of the upper roller 2-1-2 of the short roller mounting plate 2-2-1 and the end surface of the upper roller 2-1-2 of the long roller mounting plate 2-1-1 is smaller than the width of the mold 3 by 8 mm. The rest is the same as in Example 1.

Abstract

Disclosed are a die casting machine and a method for automatically separating a die from the die casting machine. The die casting machine comprises a die casting machine body, wherein the die casting machine body comprises a horizontal lower die slide beam, and further comprises a spring clamping positioning mechanism and a chain transmission mechanism, the spring clamping positioning mechanism is located on the upper surface of the lower die slide beam, two parallel grooves are formed in the upper surface of the lower die slide beam, the spring clamping positioning mechanism comprises a positioning mechanism and a clamping mechanism, the positioning mechanism and the clamping mechanism are respectively located on the outer sides of the two parallel grooves, which are opposite, the positioning mechanism comprises a long roller wheel installation plate, the long roller wheel installation plate is parallel to the grooves, and fixed together with the lower die slide beam, idler wheels are arranged on the long roller wheel installation plate, and two ends of the long roller wheel installation plate are both in arc shape so as to form guide angels. The die casting machine and the method for automatically separating the die from the die casting machine can achieve continuous production of various die casting products, and improve production efficiency.

Description

Technical field [0001] The invention relates to the technical field of die casting, in particular to a die casting machine and a method for automatically separating a mold from the die casting machine. Background technique [0002] Die casting (full name: pressure casting) is a casting method in which molten metal is poured into a press chamber, the cavity of a steel mold is filled at high speed, and the molten metal is solidified under pressure to form a casting; the die casting machine is in die casting Provide die casting pressure during the process. [0003] In the existing die-casting technology field, the design form of the mold and the die-casting machine are basically fixed, and the upper mold and the lower mold have a fixed relative position. Once installed in place, this fixed mold and the die-casting machine cannot be separated automatically. When performing special die-casting (for example, the mold cavity needs to be preheated before die-casting, and the parts need to...
