Embodiment 1

[0024] see Figure 1-6 , a processing device for die-casting mold production, comprising a bottom plate 1 and a box body 5, the box body 5 is fixedly connected to the bottom plate 1, a pouring assembly is installed on the box body 5, and a transfer device is installed on the bottom plate 1 ; Specifically, a mold 13 is installed on the transfer assembly, and the mold 13 moves on the transfer assembly. When the mold 13 moves to a specified position in the box body 5, the mold 13 is realized by pouring the assembly. Liquid metal pouring; wherein, a vacuum component is also installed in the box body 5; through the vacuum component, the mold 13 after casting can be vacuum treated, further reducing the liquid air content in the mold 13, and improving the production of the mold 13 Quality in the process; wherein, the pouring assembly includes a feeding box 10 and a feeding pipe 9, the feeding box 10 is fixedly connected to the top of the box body 5, and the feeding pipe 9 is fixedly ...

Embodiment 2

[0031] This is an embodiment. On the basis of the above-mentioned embodiments, the positioning assembly is further explained, wherein the positioning assembly includes a positioning cylinder 25 and a positioning sensor 34; The conveyor belt 4 is arranged in two sections; wherein, the positioning cylinder 25 is fixedly connected to the bracket 3 and is located between the two conveyor belts 4; the bottom of the placement seat 14 is fixedly connected with a positioning sensor 34, and the positioning sensor 34 is fixedly connected to the positioning cylinder 25 piston. The extension of the rod contacts with the positioning sensor 34 ; thereby realizing the locking of the position.

[0032] Wherein, guide plates 27 are fixedly connected to both sides of the transfer assembly in the middle, and the lateral position of the placing plate is further limited by the guide plates 27, so as to improve the actual positioning effect.

[0033] The working principle of the present invention i...

Abstract

The invention discloses a processing device for die-casting die production. The processing device comprises a bottom plate and a box body, wherein a transferring and loading device is arranged on the bottom plate; a mold is arranged on the transferring and loading assembly; a vacuum assembly is further installed in the box body. and the vacuum assembly is used for realizing vacuum treatment on a poured mold. A pouring assembly comprises a feeding box and a discharging pipe, wherein the feeding box is fixedly connected to the top of the box body. The device is contacted with a positioning sensor through the extension of a piston rod of a positioning cylinder, and then positioning of a placing plate is locked. After a mold in the box body is poured, the box body is sealed through sealing assemblies at the two ends of the box body, and the negative pressure in the box body is increased through opening of a vacuum pump, opening of a control valve I and closing of a control valve II; and after vacuum pumping is completed, the vacuum pump and the control valve I are closed and stop working, the control valve II is opened, the atmospheric pressure inside and outside the box is equal, and then the sealing assemblies reset. The mold quality can be greatly improved. The processing device has good application prospects.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a processing device for die-casting mold production. Background technique [0002] Die-casting mold is a tool for casting metal parts. The basic process of die-casting is: the molten metal is cast and filled into the cavity of the mold at low or high speed. The mold has a movable cavity surface, which cools with the molten metal Process pressure forging not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state. Existing die-casting abrasives are ejected from the casting during the manufacturing process, resulting in defects such as thermal pressure, mold sticking, surface depressions, internal shrinkage cavities, and thermal bubbles, which reduce the subsequent physical properties of the abrasive. A processing device for production. Contents of the invention ...
