Description

Technical Field

[0001] This utility model relates to the field of vacuum pump core mold technology, and particularly to vacuum pump core mold. Background Technology

[0002] Vacuum pump core molds are specialized tools used to manufacture the core components of vacuum pumps. Through precise design and processing, the dimensions, shape, and performance of the pump core are ensured to meet the requirements. The molds are usually made of high-strength materials that can withstand high temperatures and pressures, ensuring accuracy and stability during the production process. Their design must take into account the material shrinkage rate and cooling process to ensure the high quality and consistency of the final product.

[0003] In the prior art, in order to change the size of the demolding gap, the contact surface of the template is usually ground to increase the demolding gap. However, the grinding operation of the template is irreversible and cannot reduce the demolding gap. Moreover, the grinding operation is labor-intensive and inefficient.

[0004] An existing patent (publication number: CN212121578U) discloses a vacuum pump base sand core mold, comprising multiple templates connected sequentially to form a cavity for molding a vacuum pump base sand core. Adjacent templates have a demolding gap. An embedding groove is formed on the contact surface of one template, and an adjusting block is detachably fixed within the embedding groove. The top surface of the adjusting block is slightly higher than the contact surface of the template, and the top surface of the adjusting block abuts against another template, thus forming the demolding gap between adjacent templates. Furthermore, the dimension by which the top surface of the adjusting block protrudes above the contact surface of the template is adjustable, allowing for adjustment of the size of the demolding gap. This design offers advantages such as easy demolding, adjustability, and convenient operation.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing vacuum pump core molds are cleaned using handheld devices. During the cleaning process, operators must constantly adjust the position and angle of the device manually, resulting in low efficiency. Furthermore, prolonged operation can easily lead to operator fatigue, further reducing cleaning efficiency. In addition, in special usage scenarios, such as when molds urgently need to be cleaned quickly to resume production, handheld devices cannot complete the task quickly, consuming a significant amount of time, severely impacting processing progress, and causing production delays.

[0006] Therefore, a vacuum pump core mold is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a vacuum pump core mold that solves the problem that most existing vacuum pump core molds are cleaned using handheld devices. During the cleaning process, operators need to constantly manually adjust the position and angle of the device, which is inefficient and can easily lead to operator fatigue, further reducing cleaning efficiency. In addition, in special usage scenarios, such as when it is urgent to quickly clean the mold to resume production, handheld devices cannot complete the task quickly, which consumes a lot of time, seriously affects the processing progress, and causes production delays.

A dry ice spraying mechanism 2 is rotatably connected to the inner wall of the multi-angle adjustment structure 9. An air blowing assembly 3 is provided on the rear side of the dry ice spraying mechanism 2.

[0030] The dry ice spraying mechanism 2 includes a feed pipe 201, a connecting frame 202, and a spraying assembly 203. The top of the spraying assembly 203 is fixedly connected to the bottom of the connecting frame 202. The surface of the connecting frame 202 is rotatably connected to the inner wall of the multi-angle adjustment structure 9. The rear side of the feed pipe 201 is fixedly connected to the front side of the connecting frame 202.

[0031] In this embodiment: By setting up a dry ice spraying mechanism 2, which achieves flexible angle adjustment through a multi-angle adjustment structure 9, and in conjunction with the automatic displacement function of the electric telescopic component 8, the mold structure 1 can be cleaned from multiple directions. Compared with traditional handheld cleaning equipment, operators do not need to manually and frequently adjust the cleaning position and angle, avoiding the problem of incomplete cleaning caused by the limitations of manual operation.

In special use scenarios, the device can be quickly installed and disassembled, and cleaning work can be carried out quickly. In addition, the blowing component 3 set on the rear side of the dry ice spraying mechanism 2 forms a dual cleaning mode with dry ice cleaning.

Combined with the automatic displacement function of the electric telescopic component 8, it can clean mold structure 1 from multiple directions. Compared to traditional handheld cleaning equipment, operators do not need to frequently adjust the cleaning position and angle manually, avoiding the problem of incomplete cleaning caused by the limitations of manual operation. The dry ice spraying mechanism 2 can efficiently remove various types of dirt using the properties of dry ice, greatly improving cleaning efficiency and quality. By setting up the dry ice spraying mechanism 2, the mold structure 1 can be cleaned from multiple angles. The pre-installed bracket 4 on the top of structure 1 and the mounting block 5 are connected by a plug-in joint, which makes the entire cleaning device easy to disassemble. In special use scenarios, the device can be quickly installed and disassembled, and cleaning work can be carried out quickly. In addition, the blowing component 3 set on the rear side of the dry ice spraying mechanism 2 forms a dual cleaning mode with dry ice cleaning.
