Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a shell extraction structure for a compression shell casting mold. Background Art

[0002] Casting molds are a key component in the metal forming process. Casting, also known as casting, involves pouring molten metal into a mold. After the molten metal cools and solidifies, the desired metal part can be obtained.

[0003] After searching, the Chinese patent announcement number is: CN209021171U, which discloses a compression shell casting mold, which belongs to the field of casting molds. The key points of its technical solution are that it includes a movable mold fixed plate, a pad, a movable mold plate, a fixed mold plate, a fixed mold fixed plate and a base arranged in sequence. A molding sand block is provided in the fixed mold plate, and a sliding module is slidably connected to the fixed mold plate. The sliding module is against the molding sand block. A hydraulic cylinder is fixed on the side of the fixed mold plate, and the hydraulic cylinder extends a piston rod that is detachably connected to the sliding module. The advantage of this compression shell casting mold is that it is convenient to open the mold, and there will be no collision between the compression shell and the mold, which will cause damage to the mold. However, in actual use, the above-mentioned device exists. In the process of extracting the shell of the traditional compression shell casting mold, the core pulling slider is usually made of solid processing, which makes it too bulky and has poor heat dissipation effect during operation, which makes the operation complicated and inefficient. For this reason, a shell extraction structure for the compression shell casting mold is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a shell-pulling structure that is convenient for compression shell casting molds, aiming to improve the problem that the core-pulling slider in the existing technology is usually manufactured by solid processing, which makes it too heavy and has poor heat dissipation effect during operation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a shell extraction structure for a compression shell casting mold, comprising a lower module, the right side of the lower module is fixedly connected to a mounting block, the top front and rear sides of the mounting block are slidably connected to connecting plates, and core-pulling sliders are installed between the two adjacent connecting plates, a hollow groove is provided on the right side of the core-pulling slider, the top of the core-pulling slider is fixedly connected to a top cover, the bottom of the core-pulling slider is fixedly connected to a sliding block, the bottoms of the two sliding blocks are slidably connected to the inner bottom of the mounting block, a hydraulic cylinder is installed on the right side of the mounting block, a telescopic rod is installed on the top of the hydraulic cylinder, and a heat dissipation mechanism is provided inside the core-pulling slider.

[0006] Through the above technical solution: during the casting process, the mold is in a closed state, and the core-pulling slider and other parts of the mold together constitute the molding space of the product. When the product is solidified, the core-pulling slider is slid in a predetermined direction by the hydraulic cylinder and the telescopic rod, thereby disengaging from the undercut part of the product and realizing smooth demolding of the product. The interior of the core-pulling slider is designed with a hollow groove, which improves the lightweight of the core-pulling slider and enhances the heat dissipation effect of the core-pulling slider.

[0015] Through the above technical solution: the lower module is supported by the limit plate in conjunction with the base, and the limit plate also plays a limiting role, ensuring that the equipment on the base has enough space for normal operation.

[0016] As a further description of the above technical solution:

[0017] The bottom of the lower module is fixedly connected to a cylinder, one end of the cylinder is fixedly connected to a top column, and the four corners of the top of the lower module are fixedly connected to limiting columns.

[0018] Through the above technical solution: the formed parts are ejected by the cylinder in conjunction with the ejector, thereby improving the demoulding efficiency.

[0019] As a further description of the above technical solution:

[0020] The four corners on the top of the base are all fixedly connected with sliding rods, and the outer walls of the plurality of sliding rods are all fixedly connected with springs.

[0021] Through the above technical solution: the sliding rod and the spring cooperate with each other to achieve the up and down lifting of the lower module, so that the mold can be used normally.

[0022] As a further description of the above technical solution:

[0023] A plurality of connection holes are provided on the front and rear sides of the base, and a plurality of ejector pins are fixedly connected to the top of the base.

[0024] Through the above technical solution: ejector pins are set in different small areas of the mold groove, which can avoid the parts from breaking during the demoulding process and play a good auxiliary effect.

[0025] As a further description of the above technical solution:

[0026] A mold groove is provided on the top of the lower module, a blind hole is provided on the front side of the lower module, and a heating hole is provided on the left side of the lower module.

[0027] Through the above technical solution: the parts in the mold are heated in real time through the heating holes to avoid heat loss during part processing.
