Technical Field

[0001] The utility model relates to the technical field of hot pressing moulds, in particular to a hot pressing laminating mould. Background Art

[0002] In order to facilitate the carrying and use of wearable smart devices such as smart headphones, smart watches and smart glasses, corresponding packaging shells are usually selected. As the demand for use increases, the requirements for the material texture of the packaging also increase accordingly.

[0003] Among them, there is a packaging box body, which includes a shell, which can be divided into an upper shell and a lower shell, and a felt layer is attached to the surface of the upper shell and the lower shell, and the upper and lower shells are integrally connected by a layer of felt layer; in order to make the upper shell and the lower shell closed to each other, a zipper is also provided at the opening edge of the shell, and the zipper is fixed on the felt layer. The two shells are opened and closed by the zipper, and the corresponding wearable products are placed in the box body. The felt layer can effectively enhance the overall texture of the packaging box.

[0004] When the zipper is fixed to the felt layer, sewing is usually used, but sewing requires more manual work and the overall processing efficiency is not high. In addition, corresponding hot pressing equipment is also used for hot pressing.

[0005] However, the current hot pressing devices have many limitations. For example, the hot pressing equipment in the prior art only needs to perform hot pressing on zippers on flat materials, but for the contour of the box body, it is not only necessary to perform hot pressing in an arc state, but also necessary to hot press the zipper to the inner edge of the box body to ensure that the product has a good appearance structure, which is quite difficult. Therefore, in the prior art, there is still a lack of a mold structure that can perform hot pressing on the inner edge of the box body, so it needs to be improved. Utility Model Content

[0037] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] In the description of the present utility model, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centrally arranged component at the same time.

[0039] The following is combined with Figure 1-8The technical solution of the utility model is further explained through specific implementation methods.

[0040] Please refer to Figure 1 The embodiment of the utility model provides a hot pressing laminating mold, which mainly includes an upper mold 1 and a lower mold 2. The upper mold 1 is located above the lower mold 2, and the lower mold 2 is used for placing and positioning the shell and the zipper; the upper mold 1 can be raised and lowered, and then opened and closed with the lower mold 2. At the same time, a heating component is fixedly provided on the upper mold 1 and a circumferential core pulling mechanism 3 is movably provided. The heating component is used to heat the circumferential core pulling mechanism 3. When the upper mold 1 is closed to the lower mold 2, the circumferential core pulling mechanism 3 is used to hot press the zipper to the inner edge of the shell.

[0041] Reference Figure 2 and Figure 3 In order to facilitate the placement of the zipper, the lower mold 2 is provided with a zipper groove 5 for placing the zipper. At the same time, in order to facilitate the placement of the shell, the lower mold 2 is provided with a shell groove 6 for placing the shell. Among them, a layer of felt is attached to the surface of the shell in advance. Before the shell is placed in the shell groove 6, a layer of hot pressing glue can be applied in advance near the inner edge of the opening to facilitate subsequent hot pressing molding.

[0042] Specifically, the lower mold 2 includes a lower mold base plate 21, a shell plate 22 and a zipper plate 23. The lower mold base plate 21 plays a supporting role and is usually placed horizontally on a carrier such as a desktop or a rack. The shell plate 22 is located above the lower mold base plate 21; wherein, the shell groove 6 is recessed at the top of the shell plate 22, and the contour of the shell groove 6 is contoured to the shell appearance contour of the product. When the shell is placed in the shell groove 6, the groove wall of the shell groove 6 fits with the shell, providing a stable support and positioning effect for the shell.

[0043] Further, refer to Figure 3 and Figure 4 In order to position and place the zipper, first, a avoidance opening 7 is set through the middle of the zipper plate 23. When setting, the size of the avoidance opening 7 should not be smaller than the size of the circumferential core-pulling mechanism 3 to facilitate the circumferential core-pulling mechanism 3 to pass through the avoidance opening 7.

[0044] At the same time, the zipper plate 23 is integrally connected with a convex edge 231 protruding toward one side, the convex edge 231 is located at the inner edge of the avoidance opening 7, and extends circumferentially along the avoidance opening 7; the zipper groove 5 is recessed from the outside to the inside on the outer side of the convex edge 231, and extends along the contour of the convex edge 231, here, the zipper teeth can be embedded in the zipper groove 5 along the arc contour, thereby realizing the positioning of the chain part.

[0045] In addition, a receiving recess 51 for accommodating the zipper head is provided on the shell plate 22. The receiving recess 51 is adjacent to the zipper groove 5 and is connected to the zipper groove 5. At this time, the zipper head can be placed in the receiving recess 51 to avoid interference with subsequent assembly actions caused by the larger head, so that the zipper can achieve final positioning.

[0046] Based on this, the zipper plate 23 is movably covered on the shell plate 22. When the zipper plate 23 is covered on the shell plate 22, the convex edge 231 extends into the shell groove 6, and the zipper groove 5 is opposite to the groove wall of the opening area of ​​the shell groove 6. In this state, the zipper groove 5 is located at the opening position of the shell groove 6, and the zipper groove 5 extends along the circumference of the shell groove 6. The zipper located in the zipper groove 5 can intersect with the opening edge of the shell, thereby realizing precise positioning between the zipper and the shell. The two are not easy to deviate, which provides favorable conditions for subsequent hot pressing processing.

[0047] Further, continue to refer to Figure 3 and Figure 4 In order to improve the covering accuracy between the zipper plate 23 and the shell plate 22, a plurality of positioning posts 221 are fixedly provided on the shell plate 22; at the same time, a plurality of positioning holes 232 are penetrated at the corresponding positions of the zipper plate 23. By inserting the positioning posts 221 into the positioning holes 232, the mutual positioning between the zipper plate 23 and the shell plate 22 is achieved, and the assembly accuracy of the two is guaranteed.

[0048] It should be noted that, for ease of operation, in this embodiment, the housing plate 22 is slidably disposed on the lower die base plate 21 along the horizontal direction; Figure 2 Usually, a slide rail can be fixedly installed on the lower mold base plate 21, and a slide table can be fixedly installed on the bottom of the shell plate 22. The slide table is slidably installed on the slide rail to achieve horizontal sliding cooperation. Here, through the above arrangement, the shell plate 22 and the zipper plate 23 can be moved to the outside of the mold by horizontal sliding, so as to facilitate the loading and unloading operations of the zipper and the shell.

[0049] After the shell and the zipper are installed in place, the upper mold 1 needs to be closed in the lower mold 2, and then the circumferential core pulling mechanism 3 and the heating component cooperate with each other to hot press the zipper to the shell.

[0050] To achieve hot pressing action, refer to Figure 5 and Figure 6The upper die 1 mainly includes an upper die base plate 11 and a floating plate 12. The upper die base plate 11 plays a bearing role. In this embodiment, in order to improve the overall strength of the upper die base plate 11, the upper die base plate 11 is composed of multiple sub-plates, and its structure is not described here; and the upper die base plate 11 is located directly above the lower die 2 and is connected to a telescopic cylinder such as a cylinder or a hydraulic cylinder. The telescopic cylinder drives the upper die base plate 11 to move up and down, and the upper die base plate 11 slides through the guide assembly 4.

[0051] Specifically, the guide assembly 4 includes a guide column 41 and a guide sleeve 42. The guide column 41 is vertically arranged, and the bottom end is fixedly installed on the lower mold base plate 21. In addition, a mounting hole is opened on the upper mold base plate 11, and the guide sleeve 42 is fixedly installed in the mounting hole. The guide sleeve 42 is slidably sleeved in the guide column 41. The guide column 41 guides the sliding sleeve to improve the accuracy of the upper and lower molds 2 during opening and closing.

[0052] It should be noted that the guide pins 41 and guide sleeves 42 that cooperate with each other can be multiple groups, and several groups of guide pins 41 and guide sleeves 42 are evenly arranged between the upper mold base plate 11 and the lower mold base plate 21. In this embodiment, the guide pins 41 and guide sleeves 42 that cooperate with each other are selected as four groups, and are arranged in a rectangular arrangement at the corners of the upper mold base plate 11 and the lower mold base plate 21, playing the role of multiple groups of guides, and the opening and closing stability between the upper mold 1 and the lower mold 2 is optimized and improved.

[0053] Continue to refer to Figure 5 and Figure 6 During the lifting and lowering process, the floating plate 12 is mainly used to close the mold with the lower mold 2, wherein the floating plate 12 is located below the upper mold base plate 11, and is elastically floatingly arranged on the upper mold base plate 11; in the specific setting, a limit screw can be threadedly installed on the upper mold base plate 11, and at the same time, a through hole is penetrated at the floating plate 12, and the limit screw passes through the floating plate 12 through the through hole, and the limit screw is threadedly connected to the upper mold base plate 11, at this time, the limit screw plays a role in limiting the floating plate 12, further, a spring is installed between the upper mold base plate 11 and the floating plate 12, and under the action of the spring, the floating plate 12 can elastically float compared with the upper mold base plate 11.

[0054] Based on the above arrangement, during the mold closing process, the floating plate 12 will first abut against the lower mold 2 , and as the upper mold 1 continues to move downward, the floating plate 12 and the upper mold base plate 11 are brought closer to each other by squeezing the spring.

[0055] At the same time, refer to Figure 6 and Figure 7The circumferential core-pulling mechanism 3 includes a slider assembly 31 and a core-pulling block 32. The core-pulling block 32 is fixedly mounted on the upper mold base plate 11. During the specific installation process, an avoidance hole needs to be provided through the floating plate 12. The core-pulling block 32 passes through the floating plate 12 through the avoidance hole and slides with the slider assembly 31. The core-pulling block 32 is used to drive the slider assembly 31 to open or gather compared to the middle part of the floating plate 12, thereby achieving the effect of circumferential multi-directional pressing of the zipper.

[0056] Reference Figure 6 , 7 8. To achieve a multi-directional pressing effect, in the present embodiment, the slider assembly 31 is slidably disposed on the floating plate 12. Specifically, the slider assembly 31 includes a circumferential slider 311 and an angled slider 312. It should be explained that the middle of the floating plate 12 referred to here can be understood as the middle position of the floating plate 12 on the geometric center. With this position as a reference, straight slide rails are fixedly installed around the floating plate 12, one end of which is toward the middle of the floating plate 12. The straight slide rails are used to guide the circumferential slider 311 to move closer to or farther away from the middle of the floating plate 12.

[0057] Furthermore, the number of circumferential sliders 311 is consistent with the straight guide rail. Specifically, in the present embodiment, there are four circumferential sliders 311, which are respectively arranged at four positions of the front, rear, left and right around the floating plate 12. In order to achieve sliding assembly, it is necessary to set a straight guide groove on the circumferential slider 311, and install the circumferential slider 311 to the straight guide rail through the straight guide groove to achieve sliding assembly.

[0058] Furthermore, usually, the cross-sectional shape of the straight slide rail and the straight slide groove can adopt a dovetail profile, and a T-shaped structure can also be adopted in other embodiments. Through the above-mentioned structural setting, the circumferential slider 311 can be less likely to loosen and the sliding action can be more stable. The structure of the straight slide rail and the straight slide groove is not limited here, and any structure that can improve the sliding stability can be tried, and no specific restriction is made here; based on this, under the sliding cooperation of the straight slide groove and the straight slide rail, the circumferential slider 311 can be closer to or farther away from the middle of the floating plate 12.

[0059] Furthermore, the number of the angled sliders 312 is also set to four in the present embodiment. Any angled slider 312 is arranged between two adjacent circumferential sliders 311. The four angled sliders 312 are respectively distributed in a total of four diagonal gaps formed between any two adjacent circumferential sliders 311, and the two sides of the angled slider 312 are respectively pulled and cooperated with the two adjacent circumferential sliders 311. At this time, the four angled sliders 312 and the four circumferential sliders 311 form a module structure with a closed trajectory in the horizontal circumferential direction.

[0060] Further, refer to Figure 7In order to achieve traction cooperation between the bevel slider 312 and the circumferential slider 311, a first inclined cooperation structure 8 is provided between the bevel slider 312 and the circumferential slider 311. The first inclined cooperation structure 8 includes horizontal inclined rails respectively integrally arranged on the opposite sides of the bevel slider 312. The horizontal inclined rails are arranged horizontally and inclined relative to the moving direction of the circumferential slider 311; accordingly, a horizontal inclined groove for sliding cooperation of the horizontal inclined rails is recessed at a relative position of the circumferential slider 311. At this time, if the bevel slider 312 is driven to move horizontally toward the outer side of the floating plate 12, the first inclined cooperation structure 8 will generate a component force, thereby pushing the circumferential sliders 311 on both sides of the bevel slider 312 to move outward, and finally making the bevel slider 312 and the circumferential slider 311 abut against the shell plate 22 at the same time, completing the action of pressing the zipper to the edge of the shell.

[0061] Furthermore, the movement of the angled slider 312 is driven by the core-pulling block 32. Specifically, Figure 8 A second inclined matching structure 9 is provided between the core pulling block 32 and the angled slider 312. The second inclined matching structure 9 includes a T-shaped slide rail inclined relative to the horizontal plane. The T-shaped slide rail is integrally arranged at the core pulling block 32. At the same time, the second inclined matching structure 9 also includes a T-shaped slide groove inclined relative to the horizontal plane. The angled slider 312 is slidably matched on the T-shaped slide rail through the T-shaped slide groove.

[0062] Based on the above settings, the coordination process of the angled slider 312, the circumferential slider 311 and the inclined core pulling block is as follows: during the mold closing process, the upper mold 1 descends until the floating plate 12 abuts against the lower mold 2. At this time, the upper mold 1 can continue to descend for a distance under the buffering of the spring, thereby driving the core pulling block 32 to extend downward compared to the floating plate 12. The core pulling block 32 pushes the angled slider 312 toward the outside of the floating plate 12 under the action of the second inclined coordination structure 9. Under the action of the first inclined coordination structure 8, the angled slider 312 moves toward the outside while driving the circumferential slider 311 to move toward the outside, thereby finally realizing the opening action of the slider assembly 31.

[0063] Furthermore, combined with Figure 7 In order to achieve the gathering of the slider assembly 31, the slider assembly 31 also includes an elastic member 33. The elastic member 33 is selected as a compression spring in this embodiment. The two ends of the elastic member 33 are fixedly connected to the circumferential slider 311 and the floating plate 12 respectively; through the above arrangement, when the upper mold 1 and the lower mold 2 are closed, the circumferential slider 311 squeezes the elastic member 33 to compress the elastic member 33; then, when the upper mold 1 is opened compared to the lower mold 2, the floating plate 12 is reset, and the core pulling block 32 drives the angled slider 312 to retract, providing movement space for the circumferential slider 311. At this time, the elastic member 33 is in a natural state, pushing the circumferential slider 311 to retract toward the middle of the floating plate 12 to achieve the gathering action.

[0064] Furthermore, in order to improve the stability of the slider module during movement, the two sides of the core pulling block 32 can be respectively connected to two adjacent angled sliders 312. For example, in the present embodiment, two core pulling blocks 32 are provided and arranged in a mirror image. Any core pulling block 32 is connected to two angled sliders 312 at the same time. With such a configuration, the two angled sliders 312 can be driven to move at the same time, so that the structure is evenly stressed and operates smoothly.

[0065] It should be noted that the heating component can adopt a conventional electric heating rod structure, and the electric heating rod is embedded in the circumferential slider 311 or the angled slider 312 to achieve a heating effect, and its specific installation method is not described here.

[0066] Please look back Figure 5 Furthermore, in order to avoid excessive collision between the upper mold 1 and the lower mold 2, it is necessary to limit the stroke of the upper mold 1, wherein a limiting column 10 is fixedly arranged at the lower mold base plate 21 of the lower mold 2. The limiting column 10 can be set in multiple pieces, which will not be elaborated in detail here. The limiting column 10 is vertically arranged, and the bottom end abuts against the lower mold base plate 21, and the top end abuts against the floating plate 12 for limiting, which plays a role in protecting the mold and can extend the overall service life of the structure.

[0067] The implementation principle of the embodiment of the present application is: first, place the shell in the shell groove 6 of the shell plate 22, and place the zipper in the zipper groove 5 of the zipper plate 23, then cover the zipper plate 23 on the shell plate 22, and push the zipper plate 23 and the shell plate 22 to the bottom of the lower mold 2 to perform the closing operation. When the upper mold 1 and the lower mold 2 are closed, the circumferential core pulling mechanism 3 extends into the shell groove 6. Under the action of the core pulling block 32, the slider assembly 31 presses the zipper to the shell along the circumferential direction. The heating assembly is responsible for heating the circumferential core pulling mechanism 3 so that the circumferential core pulling mechanism 3 hot presses the zipper to the shell.

[0068] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
