Embodiment 1

[0046]Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0047] Such as figure 1 , 2 Shown in and 3, a kind of molding sand automatic production system for precision casting, comprises core shooter 1, also comprises:

[0048] Guide mechanism 2; in this embodiment, the mobile trolley 31 moves along the guide mechanism 2 to transfer the molding sand formed by the core shooter 1 to the output station;

[0049] A blanking mechanism 3, the blanking mechanism 3 includes a transfer trolley 31 moving along the guide mechanism 2, a material receiving assembly 32 arranged on the transfer trolle...

Embodiment 2

[0054] Such as figure 1 , 2 As shown in and 7, the parts identical or corresponding to those in the first embodiment adopt the reference numerals corresponding to the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below; The difference is that: the material receiving assembly 32 includes a plurality of guide posts 321 arranged vertically and parallel on the upper surface of the mobile trolley 31 , and a receiving portion 322 which is arranged in a sliding fit with the guide posts 321 and is in a horizontal state. And the elastic portion 323 arranged between the receiving portion 322 and the mobile trolley 31; in the present embodiment, the guide columns 321 are set in four, which are evenly distributed on the four corners of the mobile trolley 31, and are received by the guide columns. While the part 322 is limiting, the elastic part 323 is used to pull the receiving part 322 to improve the stability during its upwar...

Embodiment 3

[0059] Such as figure 1 , 2 , 7 and 9, the parts identical or corresponding to the second embodiment adopt the reference numerals corresponding to the second embodiment. For the sake of simplicity, only the differences from the first embodiment are described below; The difference between the two is that the finishing assembly 34 includes a cleaning part 341 for cleaning the inside of the upper mold 11, a spraying part 342 located on the side of the cleaning part 341 for spraying release agent on the cleaned upper mold 11, and The transmission assembly 33 is intermittently connected to control the spraying part 342 and the cleaning part 341 to intermittently perform air spraying and release agent spraying control part 343 and the air supply part 344 to supply airflow to the spraying part 342 and cleaning part 341 ; In the present embodiment, the finishing assembly 34 is fixedly arranged on the bottom of the receiving part 322, and the mobile trolley 31 drives the receiving par...

Abstract

The invention relates to the technical field of casting production, in particular to a fully-automatic molding sand production system and method for precision casting. The fully-automatic molding sandproduction system comprises a core shooting machine, a guide mechanism, a drop mechanism and an output mechanism, wherein the drop mechanism comprises a transfer car, a material receiving assembly arranged on the transfer car, a transmission assembly which is fixedly arranged on an upper mould of the core shooting machine for driving the material receiving assembly to move upwards, and a clear-upassembly which is used for cleaning the surface of the de-molded upper mould; the output mechanism is used for pushing and outputting molding sand on the drop mechanism; in a moving process of the drop mechanism, positive-pressure gas flow guide-in is performed on the clear-up assembly; a bearing part is driven to move upwards to perform molding sand bearing while the upper mould moves upwards toperform molding sand de-molding, and the transmission assembly clears up the de-molded upper mould and sprays a mould release agent, so that fully-automatic treatment for clearing the upper mould andspraying the mould release agent in the molding sand de-molding process is realized, and therefore, the technical problem that automation degree on molding sand transfer or upper mould treatment in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of casting production, in particular to a fully automatic production system and method for precision casting molding sand. Background technique [0002] In the field of foundry production, the core shooter is widely used as a semi-automatic production equipment for fast molding sand molding production. In the traditional molding sand molding process, after the molding sand is manually accepted, the surface of the concave mold is cleaned. Finally, the release agent is sprayed, and the whole process is realized by manual operation. For mass molding sand molding production, the workload is relatively large and the production cost is high. [0003] Chinese Patent Application No. 2017202252307 discloses a device for auxiliary spraying of release liquid for a vertical split tankless injection molding machine. Including the release liquid barrel, nozzle, release liquid pipe, compressed air pipe, the release liquid...
