Embodiment Construction

[0125] Embodiments of the manufacturing apparatus of the upper and lower casting molds without a sandbox according to the present invention will be described in detail below with reference to the accompanying drawings.

[0126] Figure 1- image 3 As shown, the manufacturing device of the upper and lower casting molds without sandbox uses the upper and lower extrusion plates as the extrusion device.

[0127] The manufacturing device of the upper and lower casting molds without a sandbox structurally includes:

[0128] a machine 1 of rectangular shape with an inner space;

[0129] Two pairs of mold-making upper boxes and mold-making lower boxes 2, 3, 2, 3 respectively provided with molding sand blowing inlets on the side walls;

[0130] Through the delivery of the transport device 4, the double-sided template 5 can enter and exit between the pair of upper molding boxes and the lower molding boxes 2, 3 of the two pairs of molding upper boxes and molding lower boxes 2, 3, 2, 3 ...

Abstract

The invention provides a method and a device for manufacturing an upper and lower casting mold without a sandbox. The double-sided templates are clamped by the horizontal mold-making upper box and mold-making lower box with sand blowing inlets on the side walls; the upper and lower extrusion devices are respectively inserted into the mold-making upper box and the mold-making lower box without double-sided templates. The opening of the upper and lower mold-making spaces is formed; a pair of mold-making upper boxes, mold-making lower boxes and double-sided templates rotate to a vertical state, and the molding sand blowing inlet moves upward; the molding sand blowing inlet moves up and down two molding spaces Fill the molding sand inside; the upper and lower extrusion devices enter the upper and lower molding spaces and squeeze the molding sand in the spaces respectively, and a pair of molding upper boxes, molding lower boxes and double-sided templates return to the horizontal state; After the pair of mold-making upper boxes and mold-making lower boxes are separated from the double-sided templates, the double-sided templates are pulled out from the pair of mold-making upper boxes and the mold-making lower boxes; during the above process, if necessary, After the core is set inside the casting mold, the mold-making upper box and the mold-making lower box containing the casting mold are matched with each other; the casting mold is pulled out from the matched pair of mold-making upper box and mold-making lower box.

Description

technical field [0001] The invention relates to a method and device for manufacturing an upper and lower casting mold without a sandbox, and a method and device for exchanging double-sided templates. Background technique [0002] As a kind of existing such molding device, it comprises structurally: [0003] A device is located above the abutment and squeezes the molding sand in the horizontal direction, and a device is located near the surface of the abutment to make a mold-making upper box fit with a mold-making lower box in a vertical direction and take out the mold. Two pairs of mold-making upper boxes and mold-making lower boxes alternately reciprocate, thereby obtaining upper and lower molds without sandboxes that fit each other. [0004] However, there are many problems in the manufacturing device of the upper and lower casting molds without a sandbox, such as the low efficiency of mold making, the quality of the casting mold needs to be improved, the exchange of doub...
