Embodiment 1

[0060] In this embodiment, the main structure of the mold assembly is mainly introduced.

[0061] Refer to attached figure 1 As shown, a mold assembly for ejection and demoulding of a molded part in this embodiment includes:

[0062] A mould, the mold includes a movable template 16 and a fixed template 13, the movable template 16 and the fixed template 13 form a closed pouring cavity, and the pouring sleeve on the pouring cavity is connected with a nozzle 26, and the nozzle 26 sprays the pouring liquid so that the pouring cavity forms a molded part;

[0063] Ejection assembly, the ejection assembly is inserted into the fixed template 13, when the mold assembly is demoulded to a certain distance, the ejection assembly is driven by the movable template 16, and the formed part on the fixed template 13 Ejection to realize the ejection and demoulding of molded parts.

[0064] In the present invention, first of all, by increasing the ejector assembly, and then when the moving tem...

Embodiment 2

[0068] Refer to attached figure 1 As shown, in this example, each individual part is emphasized.

[0069] Specifically, refer to the attached figure 2 As shown, the ejection assembly at least includes an ejection rod 6, and the fixed plate 13 is provided with a first slide hole 31 matched with the ejection rod 6; The first sliding hole 31 cooperates to realize the insertion and ejection of the ejector rod and the fixed template.

[0070] Specifically, the fixed template 13 is provided with four (Φ20) first round holes, and the first round holes cooperate with the small outer circle sliding H7 / f8 of the reset rod 10 (gap 0.02-0.04).

[0071] In this embodiment, since the first sliding hole 31 is arranged on the fixed template, the ejector rod 6 can slide in the fixed template 13. When demoulding, the entire fixed template 13 does not move, that is, at the beginning, the fixed template 13 and the ejector The rods 6 do not move, and as the demoulding proceeds, the ejector rod...

Embodiment 3

[0107] Die assembly in the present embodiment, with reference to attached figure 1 shown, including:

[0108] Fixed template 13, described fixed template 13 is provided with some first counterbores for fixing core forming part 14;

[0109] Movable template 16, described movable template 16 is provided with some second counterbores for fixing cavity forming part 15;

[0110] After the fixed formwork 13 is connected with the movable formwork 16, the core forming part 14 and the cavity forming part 15 form a closed pouring cavity, and the pouring cavity is poured through a pouring system;

[0111] A sprue 25, the sprue 25 used for nozzle casting in the gating system is formed in the pouring cavity, and the sprue 25 is nested with a sprue sleeve 12;

[0112] Both the sprue 25 and the sprue sleeve 12 are conical holes, and the diameter of the smallest end of the sprue is 0.2-0.3mm larger than the diameter of the smallest end of the sprue sleeve 12;

[0113] During pouring, the p...

Abstract

The invention discloses a mold assembly for ejecting and demoulding a molded part and a casting construction method thereof. The mold assembly includes a mold, and the mold includes a movable template and a fixed template, and the movable template and the fixed template form a closed casting The pouring sleeve on the pouring cavity is connected with a nozzle, and the nozzle sprays the pouring liquid to make the pouring cavity form a molded part; the ejector assembly is inserted into the fixed template, and when the mold assembly is removed When the mold reaches a certain distance, the ejector component is driven by the movable template to eject the molded part on the fixed template, so as to realize the ejection and demoulding of the molded part. By adding an ejector component, the invention drives the ejector component to move when the moving template moves, realizes the ejection of the molded part, improves the demolding efficiency of the molded part, effectively utilizes the force provided by the movement of the compression molding machine itself, and makes resources efficient Using, through the drive and transmission of physical force, the formed parts can be effectively separated.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to a mold assembly for realizing mold release of molded parts through ejection and a pouring construction method thereof. Background technique [0002] At present, in the field of plastic processing, the demoulding of the mold and the demoulding of the molded parts are two steps, and these two steps need a single supporting device. Demoulding requires certain pull-out components, etc., to pull out the molded part attached to the fixed template core molded part to realize the demoulding of the molded part. [0003] In the prior art, it is time-consuming and labor-intensive to demould the molded parts, and when the injection machine itself is demoulding, it will drive the movable template to move. Affect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a mold assembly in which molded parts are demolded by means of eject...
