Description

Technical Field

[0001] This utility model relates to the field of air purifier back cover technology, specifically to a production mold for an air purifier back cover that is easy to demold. Background Technology

[0002] The back cover of an air purifier is a crucial component. It not only protects internal components, preventing dust, moisture, and other external substances from entering and safeguarding critical parts like the filter and fan, but also impacts the overall performance and user experience. Its design and function vary depending on the model and brand, but generally include protecting internal components, ensuring airflow (vents or outlets on the back cover ensure smooth airflow, crucial for maintaining purification efficiency), ease of maintenance (some back covers feature easy-to-remove structures for convenient filter replacement or cleaning), noise control (the material and design of the back cover affect noise levels; sound insulation materials or optimized designs can reduce operating noise), and aesthetic design (matching the overall style and considering user aesthetic preferences). Looking at the latest technology and design trends, some air purifiers use a portable back cover opening mechanism for easy opening and closing when cleaning or replacing internal components; others have quick-release shells for rapid disassembly and assembly of the shell and cover for cleaning, maintenance, or replacement of internal components such as the filter; some back covers also have adjustable air guides to improve airflow efficiency and allow users to adjust the airflow direction. When choosing the right air purifier back cover, you should consider the design and function of the back cover as important factors.

[0003] According to announcement number CN219235866U, this air purifier back shell production mold for easy demolding includes a support frame. The bottom left and right sides of the support frame are fixedly connected to a support bracket via nuts. Electric telescopic rods are fixedly connected to the upper and lower ends of the support bracket near the middle of the support frame. This easy-to-demold air purifier back shell production mold features a movable block. When demolding is required, the user starts a motor to rotate a rotating disc, causing impact balls to continuously strike the movable block. The movable block, through a compression spring, impacts a retaining sleeve, continuously transmitting the resulting vibration to one side of the mold, allowing the product inside the mold to be quickly demolded.

[0004] The above technology utilizes components such as electric telescopic rods and clamps to enable products inside the mold to be quickly demolded when the equipment is put into use. However, the low intensity of the continuous vibration generated by the impact may prevent the products inside the mold from being completely detached.

[0005] Therefore, in view of this, we have studied and improved the existing shortcomings and proposed a production mold for the air purifier back shell that is easy to demold. Utility Model Content

[0006] The purpose of this invention is to provide a convenient demolding mold for producing the back shell of an air purifier, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a production mold for an air purifier back shell that is easy to demold, comprising: a mold shell, on both sides of the bottom end of the mold shell, vertically extending through the circular holes on both sides of the bottom end of the mold shell, a vertical column being provided through the circular holes, a base plate being provided at the bottom end of the vertical column, a rotating shaft being provided laterally in the middle of the inner side of the mold shell, pressure plates being movably provided on both sides of the rotating shaft, a pressure block being provided at the upper end of the outer edge of the pressure plate, and a cutting plate being provided on the outer side of the pressure block;

[0008] The outer side of the vertical column is fitted with an anti-assist structure.

[0009] Furthermore, the mold shell has an outer shape consisting of a holding part and a bottom protrusion, which makes it easy for the mold shell to distinguish between the material holding part and the external connection part.

[0010] Furthermore, the rotating shaft and the pressure plate form a flipping structure, which facilitates the upward movement of the pressure plate.

[0011] Furthermore, the top edge of the excavator is slightly lower than the upper edge of the inner side of the mold housing, which facilitates the installation of the excavator.

[0012] Furthermore, the anti-assist structure includes a compression spring, a compression ring, and a blocking rod. The upper end of the outer side of the vertical column is fitted with a compression ring, the bottom end of the compression ring is fixedly provided with a compression spring, and a blocking rod extends from one side of the compression ring. The blocking rod has a trapezoidal shape to facilitate the blocking rod to fit the shape of the mold shell.

[0013] Furthermore, the compression spring can effectively reduce the descent speed of the pressure cylinder ring, making it easier for the barrier rod to gently touch the surface of the mold housing when it descends.

[0014] Furthermore, the length of the transverse portion of the barrier rod located at the upper end of the mold housing is equal to half the length of the mold housing, so that the combined length of the barrier rod can completely block the transverse plane of the mold housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When the product is placed inside the mold shell, the mold shell begins to sink under the pressure of the internal weight. The vertical column at the bottom of the mold shell moves upward inside the mold shell. The top part of the vertical column pushes the pressure plate. At this time, the pressure plates on both sides of the rotating shaft are pushed open by the upper part of the vertical column, and the pressure plates begin to be lifted to both sides. The edge of the pressure plate pushes the pressure block upward. At this time, the digging plate is set to tilt upward. In this way, the digging plate and the pressure plate push the product placed inside the mold shell out.

[0017] 2. In this utility model, when the mold shell moves downward, the bottom of the mold shell press cylinder ring moves downward. The press cylinder ring drives the blocking rod to approach the surface of the mold shell. At the same time, the compression spring slows down the downward speed of the press cylinder ring. In this way, when the product is placed inside the mold shell, the blocking rod can always block the middle of the top of the mold shell, thereby preventing large objects from hitting the surface of the mold shell.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, a mold for producing the back shell of an air purifier that is easy to demold includes: a mold shell 1, with circular holes vertically opened on both sides of the bottom end of the mold shell 1, and vertical columns 7 vertically passing through the circular holes on both sides of the bottom end of the mold shell 1, with a base plate 8 at the bottom end of the vertical column 7, a rotating shaft 2 horizontally arranged in the middle of the inner side of the mold shell 1, pressure plates 3 movably arranged on both sides of the rotating shaft 2, a pressure block 4 at the upper end of the outer edge of the pressure plate 3, and a cut-out piece 5 on the outer side of the pressure block 4;

[0026] The outer side of the vertical column 7 is fitted with an anti-assist structure 6.

[0027] The rest are as follows: Since there are circular holes on both sides of the bottom of the mold housing 1, and the upper part of the vertical column 7 is inserted into the holes on both sides of the bottom of the mold housing 1, the top part of the vertical column 7 can push the pressure plate 3, and the rotating shaft 2 can help the pressure plate 3 to tilt to both sides. The outer edge of the pressure plate 3 pushes the pressure block 4 to move upward. At the same time, the digging plate 5 and the pressure plate 3 lift the product formed by the material inside the mold housing 1. The designer can increase the area of ​​the pressure plate 3 and the digging plate 5 to help the larger material product inside the mold housing 1 to be extracted.

[0028] This has resulted in the following effects and novel technologies:

[0029] This air purifier rear shell production mold, designed for easy demolding, boasts several advantages and innovative technologies. Firstly, it offers highly efficient demolding. The mold utilizes the coordinated action of vertical column 7, rotating shaft 2, pressure plate 3, pressure block 4, and scraper 5 to facilitate demolding. The top of vertical column 7 pushes the pressure plate 3, the rotating shaft 2 assists in tilting the pressure plate 3 to both sides, the edge of pressure plate 3 pushes the pressure block 4 upwards, and the scraper 5, together with the pressure plate 3, lifts the molded product, effectively removing it from the mold shell 1 and improving production efficiency. Secondly, it is adaptable to large-volume products by increasing the number of pressure plates 3 and scrapers. The area of ​​5 allows the mold to help eject large-volume materials from the mold shell 1, enhancing the mold's applicability and reducing difficulties in demolding large-volume products. In terms of innovative technology, the unique ejection and lifting structure is particularly prominent. The structure of using the vertical column 7 for ejection and the rotating shaft 2 to assist the lifting of the pressure plate 3 is uncommon in the production molds for the rear shell of air purifiers. The simple mechanical structure achieves effective demolding. In addition, the adjustable lifting area is also a novel feature, which can increase the area of ​​the pressure plate 3 and the excavator 5 to adapt to the demolding needs of large-volume products and provide more flexibility for demolding products of different volumes.

[0030] like Figures 1-5 As shown, a mold for producing the rear shell of an air purifier that facilitates demolding is provided. The anti-collision structure 6 includes a compression spring 61, a compression ring 62, and a blocking rod 63. The upper end of the outer side of the vertical column 7 is fitted with a compression ring 62, and the bottom end of the compression ring 62 is fixedly provided with a compression spring 61. A blocking rod 63 extends from one side of the compression ring 62. The blocking rod 63 has a trapezoidal shape.

[0031] The rest, due to the pressure ring 62 on the outside of the vertical column 7 being squeezed by the lower part of the mold housing 1, the pressure ring 62 moves downward after being squeezed by the mold housing 1. At the same time, the compression spring 61 reduces the downward speed of the pressure ring 62. When the pressure ring 62 descends, it drives the blocking rod 63 to descend. At this time, the blocking rod 63 is attached to the surface of the mold housing 1. The user can replace the horizontal part of the pressure ring 62 with a flat structure, so that the blocking rod 63 can be completely attached to the surface of the mold housing 1, thereby increasing the airtightness and safety of the mold housing 1.

[0032] This has resulted in the following effects and novel technologies:

[0033] The anti-adhesion structure 6 in the production mold for the air purifier rear shell, which facilitates demolding, has multiple effects and innovative technologies. Firstly, it enhances the mold's airtightness. When the mold shell 1 presses against the pressure ring 62 in the anti-adhesion structure 6, the pressure ring 62 causes the barrier rod 63 to descend and adhere to the surface of the mold shell 1. If the transverse portion of the pressure ring 62 is replaced with a flat structure, the barrier rod 63 can completely adhere to the surface of the mold shell 1, effectively preventing external substances from entering the mold and helping to improve product molding quality and reduce impurity contamination. Secondly, it improves the mold's safety. During the structure's operation, the compression spring 61 reduces the descent speed of the pressure ring 62, making the contact process between the barrier rod 63 and the mold shell 1 more stable. This stable structure helps prevent damage or malfunction of the mold due to sudden and rapid movement of components during operation. In terms of novel technology, the unique structure and function of the barrier rod 63 are particularly prominent. The barrier rod 63 has a trapezoidal structure and can adhere to the surface of the mold housing 1 under the action of the pressure cylinder ring 62 to increase the airtightness. This technology of improving the airtightness of the mold by using a barrier rod 63 of a specific shape in conjunction with other components is relatively novel in the production mold of the rear shell of air purifiers. In addition, the adjustable fitting design is also a major highlight. It can replace the horizontal part of the pressure cylinder ring 62 with a flat structure so that the barrier rod 63 can completely adhere to the surface of the mold housing 1. This adjustable design provides a new way to improve the airtightness of the mold and reflects a novel technical idea.

[0034] Working Principle: When using this easy-to-demold air purifier back shell production mold, the base plate 8 and mold shell 1 are first installed in a suitable position. When the mold shell 1 is filled with material, the weight of the material compresses the mold shell 1, and the mold shell 1 begins to slowly descend. At this time, the top part of the vertical column 7 pushes the pressure plate 3, and the pressure plate 3, together with the rotating shaft 2, begins to be flipped upward. The outer edge of the pressure plate 3 pries the pressure block 4 to move upward, and the pressure block 4 drives the digging plate 5 to move upward. At this time, the pressure plate 3 and the digging plate 5 lift the product formed inside the mold shell 1. When the mold shell 1 begins to descend due to the pressure of the material inside the mold shell 1, the bottom part of the mold shell 1 compresses the pressure cylinder ring 62. The compression spring 61 relieves the descent speed of the pressure cylinder ring 62. The compression spring 61 drives the blocking rod 63 to descend. The blocking rod 63 blocks the surface of the mold shell 1 to prevent external objects from hitting the surface of the mold shell 1. This is the working principle of this easy-to-demold air purifier back shell production mold.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
