Description

Technical Field

[0001] The utility model relates to the technical field of ejection devices, in particular to a mold ejection device for automobile parts. Background Art

[0002] Auto parts molds mainly include stamping molds, plastic molds and casting molds. Stamping molds are used for stamping molding of automobile bodies and parts; plastic molds are used for plastic injection molding of automobile interior and exterior parts; casting molds are used for casting molding of automobile engines and chassis parts.

[0003] Demolding of automotive parts molds is a critical process that involves a variety of technologies and devices to improve efficiency and product quality. Most automotive parts are made of metal materials. When processing these parts, stamping dies are usually used to stamp them into the required shape. Since the stamping die is subjected to high pressure, a demolding device is required to assist in demolding.

[0004] The prior art patent document CN219789035U provides a mold ejection device for automobile parts. The mold ejection device for automobile parts inserts the fixing column into the corresponding through groove, and the lower mold can be placed on the fixing seat. The lower mold can be limited and fixed by the limiting mechanism, which facilitates the disassembly, assembly and replacement of the lower mold. The automobile parts to be processed are placed on the lower mold. After the automobile parts are hot-pressed by the mold machine, the automobile parts themselves are at a high temperature and will adhere to the lower mold. The automobile parts are ejected upward by the ejection mechanism, which facilitates subsequent staff to remove the hot-pressed automobile parts through the clamping parts.

[0005] In the above-mentioned prior art, although the mold ejection device for automobile parts uses a limiting mechanism to fix the lower mold, which facilitates the disassembly, assembly and replacement of the lower mold, and demolds the parts by ejecting them, without the need for manual demolding, thereby reducing safety issues, the mold ejection device for automobile parts in this patented technology requires manual pulling of the positioning rod in the limiting mechanism before demolding the parts, so that the ejector rod can be pushed upward. The temperature of the newly formed mold is high and the distance between the positioning rods is close, which can easily cause safety hazards during manual operation. In addition, the use of a vertical upward ejection demolding method can easily damage the newly formed mold. Therefore, we need a mold ejection device for automobile parts. Utility Model Content

[0006] The purpose of the utility model is to provide a mold ejection device for automobile parts, so as to solve the problem that the mold ejection device for automobile parts in the patent technology proposed in the above background technology needs to manually pull the positioning rod in the limit mechanism before the ejector rod can be pushed upward when the part is demoulded, and the temperature of the newly formed mold is high and the distance between the positioning rods is close, which may easily cause safety hazards during manual operation, and the use of a vertical upward ejection demoulding method may easily cause damage to the newly formed mold.

When the two moving blocks 303 move relative to each other, the two lower molds 304 can move in opposite directions and separate. The two lower molds 304 are connected by a connecting rod 305, which limits the movement of the lower mold 304, thereby completing the ejection and demolding of the lower part. The upper mold 306 can be lifted upward by the extension and contraction of the cylinder 307 to complete the ejection and demolding of the upper part. The demolding process does not require manual touch, reducing safety issues caused by high temperature.

[0032] Specifically, the motor 301 forms a moving structure through the screw rod 302 and the moving block 303, and the shape and size of the outer wall of the screw rod 302 matches the shape and size of the inner wall of the moving block 303. The screw rod 302 forms a moving structure through the moving block 303 and the lower mold 304.

[0033] Through the above technical solution, the motor 301 drives the screw rod 302 to rotate, and the screw rod 302 has the other half of the thread starting from the center point set in opposite directions, so that the two moving blocks 303 can move in opposite directions, thereby driving the two lower molds 304 to move in opposite directions, which can achieve the effect of left and right separated demolding.

[0038] Specifically, the workbench 1 forms a fixed structure with the blower 601 through the first screws 602 , and the number of the first screws 602 is two. The blower 601 forms a fixed structure with the support frame 4 through the air supply pipe 603 .

[0039] Through the above technical solution, a screw groove is opened at the bottom of the workbench 1, and the first screw 602 is passed through the blower 601 and rotated and tightened with the screw groove, which has the effect of fixing the blower 601, and one end of the air supply pipe 603 is always facing the demolding direction through the support frame 4, so that the air blown by the blower 601 is blown out through the air supply pipe 603, which has the effect of cooling.

[0040] Specifically, the blower 601 is fixed by the support frame 604 and the filter 605 , and the filter 605 is installed inside the support frame 604 . The support frame 604 is fixed by the second screw 606 and the nut 607 .

[0042] Working principle: When using the mold ejection device for automobile parts, first, start the blower 601. The air blown by the blower 601 is blown out through the air duct 603 to cool the mold. After the temperature drops, start the motor 301, and the motor 301 drives the screw rod 302 to rotate. When the screw rod 302 rotates, the two moving blocks 303 can move in opposite directions, thereby moving the two lower molds 304 in opposite directions, completing the demoulding of the lower mold 304. Then, by controlling the expansion and contraction of the cylinder 307, the upper mold 306 is driven to rise, and its upper half is demoulded. After the temperature drops, it can be taken out manually. After the blower 601 has been running for a long time, the second screw 606 can be manually turned and removed, and the support frame 604 can be removed, so that the internal filter 605 can be disassembled and cleaned. After cleaning, the filter 605 is installed in the support frame 604, and then the second screw 606 is used to pass through the support frame 604 and the blower 601 and tighten the nut 607 to complete the installation of the filter 605. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
