Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a template component. Background Technology

[0002] In the production process of pulp molding products, after the wet preform is formed, it needs to be placed in a hot press mold for hot pressing. In related technologies, the hot press mold includes an upper mold and a lower mold. The lower mold forms a cavity and is provided with multiple air channels with small diameters and guide grooves. The guide grooves are opened on the side of the lower mold away from the cavity. The air channels connect the cavity and the guide grooves, and the guide grooves are connected to the suction mechanism. During the hot pressing of the wet preform, the suction mechanism can generate negative pressure to absorb the moisture of the wet preform in the cavity through the guide grooves and air channels. In addition, a heating plate is connected to the side of the lower mold where the guide grooves are formed. The heating plate is used to heat the lower mold to heat the wet preform. Thus, by absorbing water and heating, the wet preform is turned into a dry preform. During the water absorption process, water will be mixed with paper scraps, and some of the paper scraps will adhere to the guide channel. Due to the heating effect of the heating plate, the lower mold will heat up, which will cause the paper scraps to carbonize and adhere to the guide channel. Therefore, it is necessary to clean the carbon deposits in the guide channel regularly. However, during the cleaning process, both the lower mold and the heating plate need to be removed, which makes cleaning inconvenient. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] Reference Figure 1 , Figure 5 and Figure 6 According to an embodiment of this application, the template assembly includes: a template 100, the template 100 having a cavity 110, the template 100 having a first air intake channel 120 and a second air intake channel 130, one end of the first air intake channel 120 being connected to the cavity 110 and the other end being connected to the second air intake channel 130, the second air intake channel 130 passing through opposite sides of the template 100 and forming an air intake port 140 on the template 100, at least one air intake port 140 being used to connect to an air intake mechanism or to insert a cleaning rod.

[0024] It is understood that the template assembly of this application is used to heat-press a wet blank to form a dry blank. The wet blank is placed in the cavity 110. During the hot pressing of the wet blank, the template 100 can be heated by the heating structure, and the cavity 110 can be emptied by the suction mechanism. The water in the wet blank in the cavity 110 will flow away through the first suction channel 120 and the second suction channel 130. It should be understood that the wet blank is formed from pulp, and the water will contain paper scraps. The paper scraps will adhere to the second suction channel 130. Since the heating structure heats the template 100 to dry the wet blank, the paper scraps in the second suction channel 130 will heat up and carbonize. Over time, carbon deposits will form in the second suction channel 130, and the carbon deposits in the second suction channel 130 need to be cleaned regularly. During the cleaning process, it is only necessary to disconnect the air inlet 140 from the air intake mechanism, and then insert the cleaning rod through the air inlet 140 on one side into the second air intake channel 130 to scrape off the carbon deposits in the second air intake channel 130 and push it out from the air inlet 140 on the other side. This allows the carbon deposits in the second air intake channel 130 to be cleaned without removing the template 100, making cleaning convenient.

[0025] Specifically, in some embodiments, during the suction process, the suction mechanism can communicate with both suction ports 140 on opposite sides of the template 100. In other embodiments, during the suction process, the suction mechanism can communicate with the suction port 140 on one side of the template 100, while the suction port 140 on the other side is blocked by a plug. During the cleaning of carbon deposits, the communication between the suction mechanism and the suction port 140 is disconnected, and the plug is simultaneously removed from the suction port 140.

[0026] Specifically, the diameter of the second air intake channel 130 is larger than the diameter of the first air intake channel 120, the diameter of the first air intake channel 120 is smaller, and the diameter of the second air intake channel 130 is larger. The flow velocity in the first air intake channel 120 is higher, and paper scraps are less likely to adhere to the first air intake channel 120. It should be understood that if paper scraps adhere to the first air intake channel 120, it is easy to cause blockage of the first air intake channel 120. The air pressure in the blocked first air intake channel 120 becomes higher, and the airflow and water flow can easily carry away the paper scraps in the first air intake channel 120. Therefore, paper scraps and carbon deposits are generally not easy to remain in the first air intake channel 120, and it is not necessary to clean the carbon deposits in the first air intake channel 120 frequently.

[0027] Specifically, in some embodiments, template 100 is a lower template, while in other embodiments, template 100 can also be an upper template. Specifically, the upper template can cooperate with the lower template to press the wet blank in the cavity 110 to squeeze out the moisture in the wet blank.

[0028] Reference Figure 1 According to some embodiments of this application, the template assembly further includes an air receiving component 200, which is detachably connected to the template 100, communicates with the air intake 140, and is used to communicate with the air intake mechanism.

[0029] Understandably, by adding an air receiving component 200 to connect the air intake 140 on the template 100 and the air intake mechanism, the connection between the air intake 140 and the air intake mechanism can be facilitated. The air receiving component 200 is detachably connected to the template 100, which facilitates the assembly and disassembly of the air receiving component 200 and the template 100. Specifically, the air receiving component 200 is also detachably connected to the air intake mechanism, which facilitates the disconnection of the air intake mechanism from the air intake 140.

[0030] Reference Figure 1 According to some embodiments of this application, multiple second air intake channels 130 are provided, and multiple air intake ports 140 are formed on the same side of the template 100 by the multiple second air intake channels 130. The air receiving component 200 is covered on one side of the template 100 to communicate with the multiple air intake ports 140.

[0031] It is understandable that, in order to hot press multiple wet preforms at one time, multiple cavities 110 are provided, and multiple second air intake channels 130 are also provided. Each cavity 110 is connected to a second air intake channel 130. The second air intake channel 130 extends along the first direction, and multiple second air intake channels 130 are distributed along the second direction. Thus, multiple second air intake channels 130 can form multiple air intake ports 140 on both sides of the template 100 in the first direction. The air receiving component 200 is covered on the side of the template 100 so that the air receiving component 200 can simultaneously connect to multiple air intake ports 140. Multiple cavities 110 are connected through an air intake mechanism so that the adsorption force in each cavity 110 is uniform. Specifically, the first direction and the second direction intersect, and further, the first direction and the second direction are perpendicular.

[0032] Of course, in other embodiments, a cavity 110 may also be connected to multiple second air intake channels 130 to disperse moisture and paper scraps, thereby preventing carbon buildup in one second air intake channel 130.

[0033] Reference Figure 3 and Figure 5 According to some embodiments of this application, the air receiving assembly 200 includes a shielding plate 210 and a connecting frame 220. The connecting frame 220 is connected to the template 100. An opening 221 is formed at one end of the connecting frame 220 away from the template 100. The opening 221 is opposite to the air intake 140. The shielding plate 210 is movably connected to the connecting frame 220 to shield or open the opening 221. An air receiving cavity 240 is defined between the connecting frame 220 and the shielding plate 210. The air receiving cavity 240 communicates with the air intake 140, the opening 221 and the air intake mechanism.

[0034] It is understood that the cross-section of the connecting frame 220 and the shielding plate 210 after connection is approximately "U" shaped, and an air receiving cavity 240 is defined between the connecting frame 220 and the shielding plate 210. During the suction process, the shielding plate 210 covers the opening 221, and the suction mechanism can communicate with the air intake 140 through the air receiving cavity 240 to achieve the effect of water absorption. During the cleaning process, the communication between the suction mechanism and the air receiving component 200 can be disconnected, and then the shielding plate 210 can be moved to open the opening 221. The opening 221 is opposite to the air intake 140, and the relative direction of the opening 221 and the air intake 140 is consistent with the extension direction of the second suction channel 130. That is, one end of the connecting frame 220 in the first direction is connected to the template 100, and the other end of the connecting frame 220 in the first direction forms the opening 221. Thus, the cleaning rod can pass through the opening 221 and the air intake 140 into the second suction channel 130 to clean the second suction channel 130. In summary, the cooperation between the shielding plate 210 and the connecting frame 220 allows for the shielding or opening of the opening 221 to facilitate air intake of the cavity 110 or cleaning of the second air intake channel 130.

[0035] Specifically, the connecting frame 220 is equipped with an air receiving head 230, which is connected to the suction mechanism through a pipe. Thus, during the cleaning process, it is only necessary to cancel the suction action of the suction mechanism to disconnect the connection between the suction mechanism and the air intake 140. Then, by opening the opening 221, the cleaning rod passes through the opening 221 and the air intake 140 to clean the second suction channel 130. It is not necessary to separate the suction mechanism from the air receiving assembly 200. Only the shielding plate 210 needs to be moved or removed, which is convenient for operation.

[0036] Reference Figure 3 According to some embodiments of this application, the air receiving assembly 200 also includes a snap-fit ​​structure 250, through which the connecting frame 220 and the shielding plate 210 are detachably connected.

[0037] Understandably, the connecting frame 220 is detachably connected to the shielding plate 210 via the snap-fit ​​structure 250. During the cleaning process, the shielding plate 210 can be quickly detached via the snap-fit ​​structure 250 to open the opening 221.

[0038] Of course, in other embodiments, the shielding plate 210 may also be hinged to the connecting frame 220.

[0039] Reference Figure 1 According to some embodiments of this application, two air receiving components 200 are provided, and the two air receiving components 200 are connected to opposite sides of the template 100.

[0040] It is understandable that the second suction channel 130 has suction ports 140 on both sides of the template 100 in the first direction, and air receiving components 200 are provided on opposite sides of the template 100 in the first direction, so that the suction ports 140 on both sides can be connected to the suction mechanism, thereby improving the suction force on the wet blank in the cavity 110, and avoiding the situation where only one side of the suction port 140 is connected to the suction mechanism, resulting in a large suction force in the cavity 110 on the side of the suction port 140 connected to the suction mechanism, while the suction force in the cavity 110 on the side of the suction port 140 far away from the suction mechanism is small, causing uneven suction force. Therefore, by connecting the suction ports 140 on both sides through the two air receiving components 200, the suction force in multiple cavities 110 is made as uniform as possible.

[0041] Reference Figure 5 and Figure 6 According to some embodiments of this application, the diameter of the first intake channel 120 is smaller than the diameter of the second intake channel 130.

[0042] Understandably, reducing the diameter of the first suction channel 120 reduces the risk of paper scraps remaining in it, thus minimizing the possibility of carbon buildup. Furthermore, a larger second suction channel 130 facilitates the insertion of the cleaning rod and reduces the impact of carbon buildup on airflow within the second suction channel 130.

[0043] At the same time, refer to Figure 2 Multiple first air intake channels 120 are provided, and multiple first air intake channels 120 are connected to a cavity 110. The multiple first air intake channels 120 have adsorption ports 150 on the inner wall of the cavity 110. The adsorption ports 150 formed on the inner wall of the cavity 110 are evenly distributed, which can make the wet embryo dehydrate evenly.

[0044] Reference Figure 6 According to some embodiments of this application, the second air intake channel 130 is located on one side of the cavity 110, and the first air intake channel 120 extends in a straight line.

[0045] It is understandable that the second suction channel 130 extends along the first direction and is located below the cavity 110. The first suction channel 120 extends in a straight line. During the production process, the second suction channel 130 can be opened first, and then a hole can be drilled from the cavity 110 toward the second suction channel 130 in a straight line to the second suction channel 130 to form a connection between the cavity 110 and the second suction channel 130, thereby facilitating the production process. In addition, the straight extension of the first suction channel 120 can facilitate the airflow within the first suction channel 120 during the suction process. Furthermore, since the diameter of the second suction channel 130 is larger than that of the first suction channel 120, by having part of the first suction channel 120 in a straight line and tilted relative to the vertical plane, the probability of the first suction channel 120 connecting with the second suction channel 130 during the forming process can be increased, reducing the possibility that the first suction channel 120 cannot connect with the second suction channel 130 normally. In addition, it can also help to make the first suction channels 120 intersect each other, so that when one of the first suction channels 120 connects with the second suction channel 130, the connection between multiple first suction channels 120 and the second suction channel 130 can be achieved.

[0046] Reference Figure 5 and Figure 6 According to some embodiments of this application, each cavity 110 is connected to a second air intake channel 130 through a plurality of first air intake channels 120.

[0047] It is understood that there are multiple cavities 110, and each cavity 110 is connected to a second suction channel 130 through multiple first suction channels 120. The first suction channels 120 have suction ports 150 formed on the inner wall of the cavity 110. The multiple first suction channels 120 form multiple suction ports 150 on the inner wall of the cavity 110, and the suction ports 150 are relatively evenly distributed to facilitate the absorption of moisture from the wet mold. Furthermore, the first suction channels 120 are relatively small in size, and by setting multiple first suction channels 120, the water absorption effect on a single cavity 110 can be guaranteed.

[0048] Specifically, refer to Figures 4 to 6 The mold cavity 110 is provided in multiple sets, which are distributed along the second direction. Multiple second air intake channels 130 are also provided, which are distributed along the second direction. Each set of mold cavities 110 is connected to one corresponding second air intake channel 130. Each set of mold cavities 110 includes multiple mold cavities 110 distributed along the first direction. All second air intake channels 130 extend along the first direction, and multiple mold cavities 110 within the same set are connected to the same second air intake channel 130.

[0049] According to some embodiments of this application, the template assembly further includes a heating structure (not shown in the figure), which is disposed on the side of the template 100 opposite to the cavity 110.

[0050] Understandably, the heating structure is in close contact with the side of the template 100 that is away from the cavity 110, so as to heat the template 100, thereby drying the wet blank, and in conjunction with the suction mechanism, forming the wet blank into a dry blank.

[0051] Specifically, the heating structure includes a heating plate and multiple heating tubes. The multiple heating tubes are inserted inside the heating plate. One side of the heating plate is in close contact with the side of the template 100 that is away from the cavity 110. Since the second air intake channel 130 is formed inside the template 100, the side of the template 100 that is away from the cavity 110 can be set as a plane, thereby increasing the contact area between the template 100 and the heating plate.

[0052] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
