[0002] With the development of the manufacturing industry, the requirements for product component assembly are becoming increasingly stringent. In mold processing such as hot press molds, injection molds, and paper-plastic molds, various products require individually matched molds based on their different shapes and structures. Due to the different cavity structures of different molds, most mold bases are also individually adjusted and processed for each mold. This is especially true for some processing molds that require stretching and covering of flexible, extensible, and expandable materials, which also require adaptation to the moving parts in the mold core. This results in higher overall costs, and the entire mold needs to be disassembled when changing processed products, which is time-consuming and affects production schedules.

[0062] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0064] It should be noted that if the embodiments of the present invention involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0065] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0066] With the development of the manufacturing industry, the requirements for product component assembly are becoming increasingly stringent. In mold processing such as hot press molds, injection molds, and paper-plastic molds, various products require individual mold matching based on their different shapes and structures. Due to the different cavity structures of different molds, most mold bases are also individually adjusted and processed for each mold, resulting in higher overall costs. Furthermore, when changing processed products, the entire mold needs to be disassembled, which is time-consuming and affects production progress.

[0067] Taking a mold structure that stretches and coats flexible, stretchable materials by hot pressing as an example, since the entire processing requires stretching the flexible material to make the finished parts uniform in color, the mold core structure design usually includes sliding blocks that can slide to directly contact the fabric. The mold frame needs to be adapted to the sliding blocks, thus requiring good precision fit. After assembly, it is a tightly fitted whole that usually cannot be separated.

[0068] In view of this, the present invention provides a universal mold base and pressure processing equipment. Figures 1 to 5 This is an embodiment of the universal mold frame provided by the present invention.

[0069] The pressure processing equipment proposed in this invention includes a universal mold frame 100 and a mold core 200. The mold core 200 can be detachably installed onto the upper mold frame 1 of the universal mold frame 100. It should be understood that the mold cores 200 of different specifications are designed to have the same locking structure, so as to be compatible with the universal mold frame 100 and realize the quick assembly and disassembly of mold cores 200 of different specifications and the universality of the mold frame.

[0070] It should be noted that the pressure processing equipment is a pressure mold, which can be a cold press mold, a hot press mold, or even a paper-plastic mold. This invention does not limit the type of mold.

[0071] For details, please refer to Figure 1 , Figure 2 and Figure 5 The general-purpose mold frame 100 includes an upper mold frame 1, a lower mold frame 2, and a locking structure 3. The upper mold frame 1 is used for the detachable installation of mold cores 200 of different specifications. The lower mold frame 2 is located below the upper mold frame 1 and is used for placing a flow tooling 300 containing the assembly to be processed. The lower mold frame 2 and the upper mold frame 1 can move relative to each other in the vertical direction. The locking structure 3 includes a locking part and a snap-fit ​​part that cooperate with each other. One of the locking part and the snap-fit ​​part is located on the upper mold frame 1, and the other is located on the mold core 200.

[0072] In the technical solution of the present invention, the locking part and the mating part are engaged to achieve quick assembly and disassembly of mold cores 200 of different specifications. That is, in the processing of the same type of product, the mold frame can remain stable after being installed on the corresponding machine. Only the mold core 200 needs to be replaced when changing to a different specification of product. It can be used to process product parts with the corresponding matching flow fit on the lower mold frame 2. It has good versatility, faster assembly and disassembly speed, saves time, and helps to speed up the production cycle. At the same time, for some working conditions with temperature requirements, the versatility of the mold frame is also conducive to maintaining the stability of the processing temperature.

[0073] It should be understood that the upper mold frame 1 can be pressed down or the lower mold frame 2 can be raised to achieve contact between the mold core 200 and the product, that is, to achieve mold closing and mating. In this embodiment, the upper mold frame 1 is driven to press down by a servo motor or other driving mechanism to cooperate with the fixed lower mold frame 2 to achieve mold closing processing.

[0074] Specifically, the following example illustrates the effect of applying flexible fabric to a curved phone case using a hot-pressing mold. The curved phone case and the fabric are placed together to form an assembly, which is then fixed on a flow tooling 300 and secured by positioning it with the lower mold frame 2.

[0075] For further details, please refer to Figure 4 The mold core 200 includes a support plate 210 and a plurality of sliders 220 disposed around the periphery of the support plate 210 and movable towards or away from the center of the support plate 210. The support plate 210 serves as a mounting base and provides support. During actual processing, the plurality of sliders 220 can move away from each other to stretch the flexible material, allowing it to extend and fit the inner wall of the phone case. The plurality of sliders 220 can also move away from each other to avoid obstructing the product during mold closing and to separate from the flexible material for demolding during mold opening. For example, [the following text is missing]. Figure 2 In this embodiment, eight sliders 220 are provided on the mold core 200, which correspond to the four corners and four straight edges of the phone case respectively. The sliders 220 corresponding to the straight edges slide horizontally or vertically, and the sliders 220 corresponding to the corners slide diagonally.

[0076] Based on the structure of the mold core 200 described above, in the setup of the universal mold base 100, it is necessary to ensure that multiple sliders 220 can still be driven after the assembly of mold cores 200 of different specifications. In this embodiment, please refer to... Figure 3The upper mold frame 1 includes a mounting plate 13, on which one of the locking part and the snap-fit ​​part is provided. The universal mold frame 100 also includes a drive structure 4, which includes multiple connectors 41 and a drive assembly. The multiple connectors 41 are located on the lower end face of the mounting plate 13 and are distributed circumferentially along the mounting plate 13. The multiple connectors 41 slide in directions toward or away from each other to connect with multiple sliders 220 of the mold core 200. The drive assembly is located on the upper mold frame 1 and is used to drive the multiple connectors 41 to move. The multiple connectors 41 use the mounting plate 13 as a mounting base and can slide together. After the mold core 200 is assembled, they can connect with each slider 220, so that when driven by the drive assembly, they can drive the sliders 220 to slide in their corresponding sliding directions, thereby realizing the function of expanding flexible materials.

[0077] It should be noted that each of the connecting members 41 can be driven individually or simultaneously. Considering that the sliding directions of each connecting member 41 are not the same, it is preferable to separate the driving of the corresponding obliquely moving connecting member 41 from the driving of the corresponding forward moving connecting member 41, so as to avoid interference when multiple connecting members 41 expand outward or retract inward at the same time. The aforementioned forward movement refers to the horizontal or vertical direction. For example, in the production process, the connecting members 41 at the four corner positions drive the four sliders 220 to move obliquely towards the center of the upper mold frame 1. Then, the four forward moving connecting members 41 drive the remaining four sliders 220 to move towards the center of the upper mold frame 1, so as to retract the sliders 220 to avoid contact with the flexible material. After contact with the flexible material, the four forward moving connecting members 41 first drive the four sliders 220 to expand outward, and then the four corner moving connecting members 41 drive the remaining four sliders 220 to expand outward, thereby realizing the extension of the flexible material.

[0078] In this embodiment, the driving assembly includes multiple driving cylinders 42, the bases of which are all connected to the upper mold frame 1, and the cylinder rods of which are correspondingly connected to the multiple connecting members 41. The multiple driving cylinders 42 are horizontally oriented cylinders, driving each connecting member 41 through the multiple driving cylinders 42, thereby indirectly controlling the slider 220 on the mold core 200.

[0079] It should be understood that some of the drive cylinders 42 can be made to work synchronously through program control. In order to improve the driving effect and avoid shaking, it is preferable to set the rod end of the drive cylinder 42 to cooperate with the connector 41 through a T-shaped rod.

[0080] This invention does not limit the specific shape of the connector 41. It can be a columnar structure directly inserted into the slider 220. In this embodiment, please refer to... Figure 2The support plate 210 has multiple clearance holes corresponding to the multiple sliders 220. Each connector 41 includes a body 411, a first connecting part 412, and a second connecting part 413. The body 411 is movably mounted to the lower end face of the mounting plate 13. The first connecting part 412 is provided on the body 411 and extends vertically. The first connecting part 412 is used to pass through the corresponding clearance hole to contact the corresponding slider 220. The second connecting part is provided on the body 411 and spaced apart from the first connecting part 412. The second connecting part 413 is used to contact the side of the corresponding slider 220 that is away from the first connecting part 412. In this structure, the structure of the slider 220 itself is not adjusted. Only a clearance hole is provided on the support plate 210 for the insertion and movement of the first connecting part 412. The second connecting part 413 is always outside the mold core 200. The cross-section of the connecting part 41 is similar to a U-shaped structure. During the assembly of the mold core 200 from bottom to top, the first connecting part 412 naturally extends into the clearance hole. At this time, the first connecting part 412 can be in clearance fit or contact fit with the slider 220. During the outward pulling action, the first connecting part 412 contacts the side of the slider 220 facing the center of the upper mold frame 1, thereby driving it to slide. At this time, the second connecting part 413 can have a certain gap with the slider 220. During the inward retraction action, the connecting part 41 moves in the opposite direction. At this time, the second connecting part 413 contacts the exposed side of the slider 220, thereby pushing it to retract. At this time, the first connecting part 412 can also be in clearance fit with the slider 220, thereby controlling the movement of the slider 220 in two directions.

[0081] Since the inward retraction process of slider 220 does not involve molding, its inward stroke is relatively wide. However, the outward expansion process of slider 220 is an extension process of flexible material, so the accuracy requirement for the outward expansion stroke is high. In one embodiment, the driving structure 4 also includes a plurality of limiting blocks 43 corresponding to the plurality of connecting parts 41. Each limiting block 43 is detachably installed on the lower end face of the mounting plate 13 and is used to abut against the side of slider 220 facing away from the center of the upper mold frame 1 during the movement of each slider 220. The limiting block 43 acts as a hard limit and abuts against slider 220, restricting its outward stretching. It can be understood that when the mold core 200 itself is provided with a limiting structure for the outward expansion of slider 220, the limiting block 43 can be removed and not used. Of course, if the limiting stroke of the limiting block 43 is greater than the limiting stroke provided by the mold core 200 itself, it will not affect the displacement of slider 220 and can also be left unremoved.

[0082] In one embodiment, please refer to Figure 2 and Figure 4Each slider 220 has a groove on the side facing away from the center of the support plate 210. The mold core 200 also includes multiple springs 230 and multiple pressure blocks 240. The multiple springs 230 are disposed in the multiple grooves. The multiple pressure blocks 240 are fixed to the side surface of the support plate 210 and correspond to the multiple sliders 220. The multiple pressure blocks 240 are used to abut against the multiple springs 230. In the natural state, due to the setting of the pressure blocks 240, the sliders 220 can always maintain a relatively stable position, that is, in a naturally retracted state. This setting is beneficial to ensure that the initial state of mold cores 200 of different specifications is similar during quick-release fitting, and all are in the retracted state, which facilitates the installation and adaptation of the connector 41. At the same time, it can prevent the first connecting part 412 from not aligning with each through hole when installing the mold core 200. It should be understood that the clearance formed by the slider 220 at the beginning should ensure that the first connecting part 412 can pass through. In actual production, the slider 220 is driven to move, which compresses the spring 230 and provides a certain clamping force to the slider 220, which is beneficial to the tight fit between the slider 220 and the first connecting part 412.

[0083] Considering the structural fit, the size of the pressure block 240 may be made relatively small, and it is prone to loosening and deformation after long-term use. Therefore, it can also be used together with the limiting block 43, with the pressure block 240 serving as an auxiliary component.

[0084] Furthermore, the mounting plate 13 is provided with multiple guide grooves, and the upper ends of the multiple connectors 41 are slidably installed into the multiple guide grooves. Preferably, the guide grooves are dovetail grooves, which can prevent the hanging fit from falling off and provide better fit accuracy. It should be understood that each slider 220 on the support plate 210 is usually guided by a sliding groove structure. Usually, when the slider 220 is designed to slide, there is a gap fit, which has a certain amount of wobble. Considering the machining error, different mold cores 200 will fall at different tolerance positions after machining, and the consistency cannot meet the accuracy. If the connector 41 is designed based on the sliding positioning of the slider 220, it will put a large burden on the mold core 200 and is prone to movement jamming. At the same time, when the consistency accuracy cannot be guaranteed, there is a large sliding guide deviation. Therefore, the present invention sets the connector 41 to slide guide separately, so that it maintains accuracy by its own sliding fit.

[0085] This invention does not limit the specific structure of the locking part and the mating part. In one embodiment, please refer to... Figure 2The locking structure 3 includes a locking sleeve 31, a mounting cylinder 32, a plurality of first balls 33, and a pusher 34. The locking sleeve 31 is located in the middle of the upper mold frame 1, and the inner wall surface of the locking sleeve 31 forms an upwardly facing snap-fit ​​ring surface 311. One end of the mounting cylinder 32 is fixed to the middle of the upper end face of the mold core 200 and can be inserted into the locking sleeve 31. The inner wall surface of the mounting cylinder 32 has a plurality of mounting holes communicating with the outside. The plurality of first balls 33 are movably installed in the plurality of mounting holes, and at least partially located within the mounting holes. The mounting cylinder 32 is located within the inner cavity of the mounting cylinder 32. The pusher 34 is located within the inner cavity of the mounting cylinder 32 and is movable in the vertical direction. The end of the pusher 34 can contact the portion of the plurality of first balls 33 located within the inner cavity of the mounting cylinder 32 to push the plurality of first balls 33 partially protruding outside the plurality of mounting holes to abut and fix them against the snap-fit ​​annular surface 311. The locking part includes the mounting cylinder 32, the plurality of first balls 33 and the pusher 34, and the snap-fit ​​part includes the locking sleeve 31. In this embodiment, the locking part is disposed on the mold core 200, and the mating part is disposed on the upper mold frame 1. Since the locking sleeve 31 forms an upward-facing snap-fit ​​annular surface 311 inside, the inner diameter of the locking sleeve 31 corresponding to the upper edge of the snap-fit ​​annular surface 311 is naturally larger than the inner diameter of the locking sleeve 31 corresponding to the lower edge of the snap-fit ​​annular surface 311. Initially, the plurality of first balls 33 are in a loose state. Since the balls are spherical, even if they protrude from the mounting hole in their natural state, they can naturally retract when squeezed by the locking sleeve 31 during assembly, without affecting the assembly. The mold core 200 is then installed. Once installed in place, when the multiple first balls 33 can correspond to the engaging ring surface 311, the pusher 34 moves upward to push the multiple first balls 33 to move away from each other, thereby abutting against the engaging ring surface 311 respectively, forming a circumferential engaging fit. Fixing the pusher 34 in this state can lock the mold core 200 onto the upper mold frame 1. The circumferential arrangement of the multiple first balls 33 can ensure good hanging force and will not cause the mold core 200 to be misaligned. When disassembling, it is only necessary to control the pusher 34 to move downward, that is, quick disassembly can be completed by driving the pusher 34 to move up and down, which is simple to operate.

[0086] It should be understood that, since the first ball 33 is spherical and moves within the mounting hole, a certain allowance is reserved at the side edge of the mounting hole during machining, so that although the mounting hole is through, it has an arc-shaped retaining edge, thereby preventing the ball from falling out of the mounting hole.

[0087] It should be understood that the locking sleeve 31 can be fixed to the mold core 200 by means of bolts 342. In other embodiments, locking can also be achieved by the cooperation of a cylindrical rod and a stepped groove, or by the cooperation of a T-slot and a T-hook; these methods will not be described in detail in this invention.

[0088] This invention does not limit the specific structural form of the pusher 34. For example, it can be a rod-shaped structure with a spherical end or a rod-shaped structure with a circular mating surface at the end. In this embodiment, in order to facilitate the quick locking of the pusher 34, the lower end of the mold core 200 is provided with a through hole that communicates with the inner cavity of the mounting cylinder 32. The inner cavity of the mounting cylinder 32 has a first cavity section and a second cavity section with successively increasing diameters. The second cavity section is provided with the plurality of mounting holes. The first cavity section communicates with the through hole and its inner wall surface is provided with internal threads. The pusher 34 includes a second ball 341 and a bolt 342. The second ball 341 is disposed in the second cavity section. The lower part of the second ball 341 contacts the plurality of first balls 33. The bolt 342 is used to extend from the through hole and be threaded to the first cavity section. The end of the bolt 342 contacts the second ball 341 so as to drive the second ball 341 to push the plurality of first balls 33 during rotation. The outer diameter of the second ball 341 is adapted to the second cavity segment and can be confined in a fixed space by the step between the first ball 33 and the first and second cavities. The outer diameter of the second ball 341 is larger than the outer diameter of the first ball 33. The operator can control the rotation of the bolt 342 by inserting a screwdriver into the through hole. The rotation process drives and pushes the second ball 341. After the screwdriver is released, the bolt 342 is naturally locked and limited. The operation is simple and facilitates quick driving and locking.

[0089] Preferably, the bolt 342 is a headless bolt 342, thus adapting to a smaller installation space. Considering assembly strength, the ball bearings are preferably steel balls.

[0090] When installing and positioning the locking sleeve 31, it can be directly machined onto the plate corresponding to the upper mold frame 1, or a separate component can be inserted with an interference fit. Considering that the plate will deform during hot pressing, in order to prevent the locking sleeve 31 from being deformed by the pressure of the plate deformation and affecting the locking effect, in one embodiment, the upper mold frame 1 includes a mounting plate 13. The mounting plate 13 has a stepped hole in the middle, so as to have a first stepped surface facing upward. The outer side of the locking sleeve 31 is correspondingly stepped to abut against the first stepped surface. The locking structure 3 also includes a pressure sleeve 36, which is disposed in the stepped hole and located on the upper side of the locking sleeve 31, to press the locking sleeve 31 tightly onto the first stepped surface. At this time, the locking sleeve 31 can be gap-fitted with the hole on the corresponding plate, and the position is fixed by the end face. At this time, even if the plate deforms, it only fills the initially reserved gap and will not squeeze and deform the locking sleeve 31.

[0091] Considering the precise fit of the shaft hole, the locking structure 3 also includes a positioning sleeve 35. The positioning sleeve 35 is disposed in the stepped hole and located on the lower side of the locking sleeve 31, and can cooperate with the mounting cylinder 32. Precision fit can be achieved by precision machining of the positioning sleeve 35, which can reduce the machining requirements of the locking sleeve 31.

[0092] In this embodiment, both the positioning sleeve 35 and the pressure sleeve 36 are provided. By adjusting the dimensions of each component, the position of the locking sleeve 31 can also be adjusted appropriately. This allows for the adaptation to locking sleeve 31 structures of different sizes.

[0093] It should be understood that in order to avoid axial wobbling of the locking sleeve 31, one of the two sections of the locking sleeve 31 with different outer diameters can be adapted to the size of the hole in the plate.

[0094] When the locking part and the mating part are centered, there is an axial rotation problem of the mold core 200 during installation. Therefore, in one embodiment, the locking structure 3 further includes an anti-rotation structure, which includes a mutually cooperating anti-rotation pin a and a mating hole. One of the anti-rotation pin a and the mating hole is provided in the upper mold frame 1, and the other is provided in the mold core 200. Please refer to... Figure 4 In this embodiment, the anti-rotation pin a and the locking part are both provided on the mold core 200, and the mating hole and the snap-fit ​​part are both provided on the upper mold frame 1.

[0095] In addition, the upper mold frame 1 includes a floating plate 11, a heat insulation plate assembly 12, and a mounting plate 13. The floating plate 11 can deflect laterally and longitudinally. The heat insulation plate assembly 12 is located at the lower end of the floating plate 11. The mounting plate 13 is located at the lower end of the heat insulation plate assembly 12. The mounting plate 13 is provided with a heating structure and is provided with either a locking part or a snap-fit ​​part. This allows the floating plate 11 to have a certain degree of flexibility after installation, enabling in-plane deflection and ensuring mold closing accuracy. Specifically, in this embodiment, the floating deflection effect is achieved by adding multiple ordinary screws and equal-height sleeves. The vertical floating gap is set to 0.2mm, and the circumferential floating gap is set to 1.0mm. The structure is simple and saves space. By limiting the size of the floating gap, the degree of floating is controlled, achieving accurate positioning.

[0096] In addition, multiple side structures are set in the circumferential direction of the mold frame structure. The side positioning blocks and positioning grooves cooperate in the vertical direction. The side positioning blocks are set on the upper mold frame 1. The positioning and guidance are achieved by the two opposite sides of the side positioning blocks fitting against the side wall of the positioning groove. With the addition of floating gap, the position of the lower mold frame 2 can be used as a reference to automatically align the position of the upper mold frame 1.

[0097] It should be understood that in this embodiment, the pressure processing equipment is a hot press mold. A heating rod is set on the mounting plate 13 to heat the corresponding template, and then the mold core 200 is heated by heat conduction and kept warm. The heat insulation plate group 12 plays a role in heat insulation and reduces heat loss.

[0098] In this embodiment, the plurality of drive cylinders 42 are locked to the peripheral edge of the float plate 11 by brackets, and the heat insulation plate group 12 is located at the middle position. That is, when the float plate 11 floats, the drive structure 4, the locking sleeve 31 and other components float synchronously.

[0099] When performing multi-cavity processing on a pressure processing equipment, multiple mold frames are set up accordingly, and the float plate 11 of each mold frame floats independently.

[0100] It should be understood that the present invention does not limit the specific number of heat insulation boards in the heat insulation board assembly 12. In this embodiment, three heat insulation boards are stacked. In other embodiments, more or fewer heat insulation boards can be set by adjusting the thickness.

[0101] It should be noted that the lower mold frame 2 is mainly used for the installation and positioning of the flow tooling 300. Proximity switches, positioning pins and threaded holes can be set on the lower mold frame 2 to facilitate the detection and positioning of the flow tooling 300.

[0102] Furthermore, the mold core 200 also includes a limiting plate installed at the lower center of the support plate 210. Multiple sliders 220 slide on the lower surface of the support plate 210, with their lower ends protruding from the support plate 210 to contact flexible materials. They can contact the edge of the limiting plate during retraction to achieve limiting during retraction. It should be understood that the shape of the limiting plate is adapted to the installation orientation of the multiple sliders 220 to form a plane and an inclined surface for limiting and blocking. At the same time, to accommodate the different sizes of the sliders 220, corresponding avoidance structures need to be set.

[0103] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
