Description
Technical Field
The utility model relates to a gypsum casting technology field, concretely relates to gypsum forming die mechanism for vacuum mold casting.
Background
The production process of gypsum casting technology mainly includes such steps as pressing wax, making shell, roasting shell, pouring, removing shell, post-treatment and inspection, and the metal parts are usually copied in batches by using fusible material (wax, plastics, etc.) as copy, firstly pressing fusible mould with metal mould on wax-injecting machine, then coating multi-layer refractory material on fusible mould, drying and hardening the refractory material coating to form shell (forming mould), then melting the fusible material in the shell to make it flow out, roasting the shell to make it firm, pouring molten liquid metal into the shell, cooling and solidifying the liquid metal in the shell, and removing shell to obtain the required metal parts.
In practical production application, because certain adhesion still exists between the formed metal after cooling solidification and the forming die, and there is not very effective instrument and method to demold the formed metal fast, for example the existing method is to utilize anchor clamps to carry out the formed metal, not only the success rate is low, and cause the damage to the formed metal easily moreover, lead to the fact the drawing of patterns inefficiency, and the effect is not good.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, the gypsum forming die mechanism for vacuum type casting is high in demoulding efficiency and good in demoulding effect.
The technical scheme is as follows: in order to realize the above-mentioned purpose, the utility model provides a gypsum forming die mechanism is used in vacuum type casting, including the mould body and mould lid, still including the fixed establishment who is used for the fixed mould body and supplementary drawing of patterns, fixed establishment includes supporting platform, two hydraulic pressure posts, cooperation set up hydraulic pressure piece and two setting elements on two hydraulic pressure posts, two the hydraulic pressure post is fixed on supporting platform, the setting element includes thread piece and locating piece, and two thread pieces transversely cooperate respectively on two hydraulic pressure posts, and two locating pieces are fixed respectively and are set up the opposite ends at two thread pieces, and two thread pieces all are located the hydraulic pressure piece below, be provided with at least one sucking disc that is used for the drawing of patterns on the hydraulic pressure piece.
Furthermore, a rotating handle is arranged on each of the two thread blocks, so that the thread blocks can be conveniently rotated.
Furthermore, two setting elements symmetry sets up on two hydraulic pressure posts, promotes the location effect.
Further, the number of the suckers is two.
Has the advantages that: compared with the prior art, the utility model, through the setting element to the location of mould with fixed to and the adsorption of sucking disc, realized forming die's high efficiency, stable drawing of patterns, and the drawing of patterns in-process can not cause the damage to the shaping metalwork, improved drawing of patterns efficiency, promoted demoulding effect.

fig. 2 is a schematic view of a molding die.
Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
As shown in fig. 1 and 2, the utility model provides a gypsum forming die mechanism for vacuum casting, which comprises a die body 1, a die cover 2 and a fixing mechanism, wherein the die body 1 is provided with a liquid inlet 11 and a liquid outlet 12, the fixing mechanism comprises a supporting platform 10, two hydraulic columns 5, a hydraulic block 6 arranged on the two hydraulic columns 5 in a matching way and two positioning pieces, the two hydraulic columns 5 are fixed on the supporting platform 10, realize reciprocating of hydraulic block 6 on two hydraulic pressure posts 5 through the hydraulic press, the bottom of hydraulic block 6 is provided with two sucking discs 7, and the setting element includes screw block 4, locating piece 3 and rotation handle 41, and locating piece 3 and rotation handle 41 set up respectively in screw block 4 both ends, and two screw blocks 4 horizontal screw-thread fit respectively are on two hydraulic pressure posts 5, and two locating pieces 3 symmetry set up between two hydraulic pressure posts 5 and are located hydraulic block 6 below.
In this embodiment, the above gypsum forming mold mechanism is used for demolding, and the specific demolding process is as follows: firstly, a die body 1 to be demoulded is placed on a supporting platform 10, two rotating handles 41 are respectively rotated, the positions of two positioning blocks 3 are adjusted, the die body 1 is adjusted and fixed under two suckers 7, then a die cover 2 is opened, a hydraulic block 6 is controlled to move downwards by operating a hydraulic machine until the two suckers 7 adsorb formed metal in the die body 1, and finally the hydraulic machine is controlled to move upwards to enable the formed metal piece to be taken out of the die body 1 by the two suckers 7, so that demoulding is completed.
According to the demolding process, the gypsum forming mold mechanism is suitable for demolding the mold bodies 1 of various specifications, high in demolding efficiency, free of damage to formed metal parts and capable of guaranteeing demolding effect.
