[0039] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0042] With the development of the manufacturing industry, the requirements for molds are getting higher and higher, especially the demand for precision molds. However, in addition to relying on precision machining machine tools, precision molds also rely on the design concept of molds, especially when there are large differences in the template temperature at different positions of the mold, a reasonable design is particularly important. For multi-hole processing, due to the influence of processing errors and temperature, although multiple holes are produced at the same time, the quality of each product obtained by the corresponding processing may be uneven. Therefore, in multi-hole processing, how to make multi-hole production have good consistency is still a topic of continuous exploration and improvement.

[0043] Taking the traditional two-cavity hot pressing mold as an example, the temperature difference at each position of the mold is huge. The temperature of the center cavity is the best and can reach the set temperature. The temperature on both sides is the lowest, less than 40°C. This leads to that even if the templates of these mold structures are made of the same material, the amount of thermal expansion is inconsistent due to inconsistent temperatures. This causes the position of the holes on each template to shift to varying degrees, resulting in the misalignment of the upper and lower molds or the movement of parts in the mold being difficult and prone to jamming. If materials with large differences in thermal expansion rates are used for each template according to the temperature distribution, even if the temperature can be the same, the amount of positional deviation of the holes on the template is uncontrollable, and there is still the problem of misalignment of the upper and lower molds or the movement of parts in the mold being difficult and prone to jamming.

[0044] In view of this, the present invention provides a multi-hole pressure processing equipment, which will not be affected by processing errors and temperature and can ensure good consistency of multi-hole production. Figures 1 to 5 This is an embodiment of the multi-hole pressure processing equipment provided by the present invention.

[0045] It should be noted that the pressure processing component can be a cold or hot pressing mold, an injection mold, a paper plastic mold, a stamping mold, etc. The following is an example of a pressure processing component being a hot pressing mold, which is used to cover flexible fabric on a mobile phone case with a curved surface.

[0046] Please refer to Figure 1 to Figure 2 The multi-hole pressure processing equipment 100 includes a bottom plate 1, a top plate 2 and a plurality of pressure processing components 3. The top plate 2 and the bottom plate 1 can move relative to each other in the up and down directions. The plurality of pressure processing components 3 are arranged between the bottom plate 1 and the top plate 2 at intervals. Each of the pressure processing components 3 includes a lower mold group 32 and an upper mold group 31. The upper mold group 32 is arranged on the top plate 2, and the upper mold group 31 includes a pressing structure 34. The pressing structure 34 can float in the up and down directions and in the horizontal direction relative to the top plate 2. The lower mold group 32 is arranged on the bottom plate 1 for placing the product to be processed. During the movement of the top plate 2 and the bottom plate 1, the upper mold group 31 and the lower mold group 32 are molded together.

[0047] In the technical solution of the present invention, multiple pressure processing components 3 can perform pressure processing on multiple products at the same time under the joint drive of the bottom plate 1 and the top plate 2, so as to achieve the effect of multi-hole production. Since the part of each pressure processing component 3 that mainly applies pressure to the product, the pressing structure 34 can float relative to the top plate 2, so that each pressure processing component 3 can be based on the current ambient temperature and its own processing error. In the mold positioning, each lower mold group 32 is used as a reference, and each pressing structure 34 floats in the up and down directions and horizontal directions, so as to achieve the purpose of self-adaptation, so as to ensure the mold closing state of each pressure processing component 3 during the mold closing process, which is conducive to ensuring good consistency of multi-hole production and avoiding position displacement due to the expansion of metal materials, thereby causing the upper mold group 31 and the lower mold group 32 in each pressure processing component 3 to be misaligned or the parts to move unsmoothly and easily get stuck.

[0048] Specifically, in each of the pressure processing components 3, the upper mold group 31 includes a connecting seat 311 and a first mounting base 312. The first mounting base 312 is arranged below the connecting seat 311 and can float in the vertical direction and in the horizontal direction relative to the connecting seat 311. The first mounting base 312 is used for local installation of the pressing structure 34. The connecting seat 311 is connected to the top plate 2. During the hot pressing production process, the temperature of the part in contact with the product is the highest, that is, the temperature of the part in contact with the material of the pressing structure 34 is the highest. In the entire mold structure, heat will be lost step by step in the direction away from the center, and the mold material is generally metal, which will expand under the action of temperature. The higher the temperature, the more it expands. This expansion deformation will affect the original shaft hole matching method on the mold structure, and the position of some templates will be offset, and the horizontal state may also change. The floating matching of the first mounting base 312 and the connecting seat 311 enables the first mounting base 312 to drive a part of the pressing mechanism to perform floating adjustment, so that when closing the mold, the cavity of the lower module 32 is used as the positioning reference to ensure the closing state.

[0049] In order to achieve floating connection, spring structures and clearance fit between structures can be designed. In this embodiment, the multi-hole pressure processing equipment 100 includes multiple floating structures 33, each of which includes a connecting member 331 and a contour sleeve 332. The connecting member 331 is installed on the connecting seat 311 through the through hole of the first mounting base 312. The contour sleeve 332 is sleeved on the outer surface of the connecting member 331 and is at least partially located in the through hole of the first mounting base 312. The outer surface of the contour sleeve 332 is stepped to form a step surface set toward the connecting seat 311, and a first floating gap is formed between the step surface and the first mounting base 312, and a second floating gap is formed between the outer surface of the contour sleeve 332 and the through hole of the first mounting base 312. Specifically, the first floating gap is a floating gap in the up and down directions, and the second floating gap is a gap in the circumferential direction, which can realize the horizontal shaking of the first mounting base 312. It is preferred to set the first floating gap to 0.2 mm and the second floating gap to 1 mm. Taking the top plate 2 as an example, when it expands due to temperature, the degree of expansion from the center to the edge is different, so that the template states of each pressure processing component 3 that is not in different positions are different. The first mounting base 312 is installed in a suspended manner, so before the mold is fully closed, each pressure processing component 3 can be adaptively adjusted to ensure that the processing state of each product remains consistent.

[0050] It should be noted that the connecting member 331 can be selected from ordinary screws, which can play the role of contour screws after being matched with the contour sleeve 332. The material of the contour screw needs to have a certain hardness requirement, and steel with a hardness of HRC52 is preferred.

[0051] For further information, please refer to Figure 3, the top plate 2 is provided with a plurality of first round holes distributed along the circumference of the top plate 2; the connection seat 311 is provided with a plurality of first waist-shaped holes 3111 corresponding to the plurality of first round holes, and the extension directions of two adjacent first waist-shaped holes 3111 intersect; the multi-hole pressure processing equipment 100 includes a plurality of first positioning pins 4, each of which passes through the corresponding first round hole and the corresponding first waist-shaped hole 3111 in sequence. That is, when the first positioning pin 4 is installed, the shape of the hole corresponding to it on different templates may be different. In the actual production process, the temperature of the top plate 2 is lower than that of the connection seat 311, so the expansion deformation is smaller. The matching method of the round hole and the cylindrical pin is conducive to precise matching, and the mutual cooperation of the plurality of first positioning pins 4 can play an anti-rotation effect. The design of the first waist-shaped hole 3111 can adapt to the expansion and deformation direction of the connection seat 311. Even if the first waist-shaped hole 3111 is deformed, the corresponding first positioning pin 4 will not be squeezed and deformed due to the pre-reserved gap, thereby improving the matching effect of each part affected by temperature.

[0052] In addition, the top plate 2 and the connecting seat 311 are connected by a plurality of equal-height screws to ensure the height position limitation of the connection strength.

[0053] It is understood that when the hot pressing mold is used to coat the flexible material on the entire inner surface of the shell part, considering the shape of the shell part, please refer to Figure 2 and Figure 4The pressing structure 34 includes a pressing block 341 and a plurality of sliding parts 342. The pressing block 341 can move in the up and down directions. The lower end surface of the pressing block 341 is used to correspond to the bottom surface of the shell part. The plurality of sliding parts 342 are arranged in sequence along the circumference of the pressing block 341. The plurality of sliding parts 342 can move in the up and down directions, and the plurality of sliding parts 342 have a movable stroke close to or away from the pressing block 341. The shape of the plurality of sliding parts 342 is used to adapt to the shell part to correspond to the peripheral side wall of the shell part and the curved surface section between the peripheral side wall and the bottom surface. The pressing block 341 and the plurality of sliding parts 342 can both move in the up and down directions, and the plurality of sliding parts 342 can also move linearly relative to the pressing block 341. The plurality of sliding parts 342 are contoured, corresponding to the peripheral side walls and curved surface segments of the shell parts, and their main function is to stretch and cover the side of the flexible material. The lower end surface of the pressing block 341 remains flat, and its main function is to stretch and cover the middle of the flexible material. In the mold closing process, as the upper mold assembly 31 falls, the pressing block 341 and the The multiple sliding parts 342 first move downward together, and then contact the flexible material. At this time, the multiple sliding parts 342 move in the direction away from the pressing block 341. The pressing block 341 can continue to move downward or maintain its height. As the upper mold assembly 31 continues to fall, since each of the sliding parts 342 moves relative to the pressing block 341 and moves up and down, the entire mold moves diagonally from top to bottom away from the center. The pressing block 341 continues to move downward, so that the stretched flexible material can be driven to fit the shell parts accordingly when the mold is closed. The mold is opened after being closed for a period of time. During the mold opening process, the sliding parts 342 should move in the direction close to the pressing block 341 to reset.

[0054] The present invention does not limit the driving mode of the movement of the sliding part 342 relative to the pressing block 341. In one embodiment, the upper mold assembly 31 also includes a driving part 343, which can move in the upper and lower directions. The driving part 343 is located between the multiple sliding parts 342, and the lower end surface of the driving part 343 is connected to the pressing block 341. The peripheral side surfaces of the lower end of the driving part 343 are all inclined from top to bottom toward the center of the driving part 343. The sides of the multiple sliding parts 342 facing the driving part 343 are all mating surfaces, and each mating surface is inclined with respect to the driving part 343. The synchronous driving of multiple sliding parts 342 by one driving part 343 is achieved by matching with the inclined surface, and good consistency is maintained. Considering the size of the sliding part 342 and the matching with other parts, the size of the inclined surface on the peripheral side of the driving part 343 can be reasonably designed.

[0055] Furthermore, on the sides of each sliding part 342 opposite to the driving part 343, one is provided with a slide groove and the other is provided with a slide rail, and the slide rail is slidably inserted into the slide groove. The form of the slide rail and the slide groove provides a good connection effect and activity guide for the sliding part 342 and the driving part 343. The slide rail and the slide groove are preferably designed to be special-shaped, for example, the slide groove is designed to be a T-shaped groove, a dovetail groove, etc. It can be understood that a good matching accuracy should be maintained to ensure the effect of sliding matching.

[0056] It should be noted that the pressing block 341 and each sliding part 342 can also cooperate with each other through a slide groove and a slide rail. However, since the pressing block 341 itself does not drive the sliding parts 342, a sufficient gap should be maintained between the pressing block 341 and each sliding part 342 to avoid interference.

[0057] Furthermore, the pressing block 341 and the sliding part 342 can both be floated. In this embodiment, in each of the pressure processing components 3, the upper mold assembly 31 includes a connecting seat 311 and a first mounting base 312. The first mounting base 312 is arranged below the connecting seat 311 and can float relative to the connecting seat 311. The connecting seat 311 is connected to the top plate 2. The driving part 343 is installed in the middle of the first mounting base 312 and can float in the vertical direction and in the horizontal direction. That is, the driving part 343 drives the pressing block 341 to be floated relative to the first mounting base 312. The vertical position of the driving part 343 and the pressing block 341 will be limited by the shell parts and the top plate 2 during mold closing, and the horizontal position can be limited by the annular mounting frame for mounting multiple sliding parts 342. Therefore, even if floating installation is performed, the accuracy of mold closing processing will not be affected. Furthermore, it can prevent the pressing block 341 and the sliding part 342 from being unable to slide along the set track due to poor matching of the various parts of the mold.

[0058] Specifically, the floating method can also be achieved by designing a floating structure 33. Specifically, the first mounting base 312 and the connecting base 311 are connected by four evenly distributed floating structures 33, and the driving part 343 and the middle part of the first mounting base 312 are connected by six floating structures 33. The size of each floating structure 33 is reasonably designed. Specifically, corresponding to the floating structure 33 of the driving part 343, the first floating gap is preferably 0.1mm, and the second floating gap is 1mm.

[0059] The present invention does not limit the specific number of the plurality of sliding parts 342, which can be reasonably arranged according to the size and shape of the shell part. In this embodiment, eight sliding parts 342 are arranged, and the plurality of sliding parts 342 include two first sliders opposite to each other in the transverse direction, two second sliders opposite to each other in the longitudinal direction, and a third slider located between each adjacent first slider and second slider. At this time, the four third sliders correspond to the four corners of the shell part, and the first slider and the second slider correspond to the long and short sides of the shell part respectively. In one embodiment, the side surface of the third slider that fits with the corresponding first slider and the second slider is inclined. Specifically, the angle between the side surface and the corresponding straight edge is 30°, which is conducive to non-interference when the sliders are separated. In another embodiment, the extension direction of the matching surface of the third slider intersects with the extension direction of the matching surface of the corresponding first slider and the second slider, that is, at this time, the pressing block 341 is correspondingly arranged in an octagonal shape. In this embodiment, the above two features are set at the same time to ensure the matching effect and sliding opening effect of the plurality of sliding parts 342.

[0060] It can be understood that the inclination angles of the inclined surfaces formed by the cooperation between the multiple sliding parts 342 and the driving part 343 can be the same or different. In this embodiment, the angle between the inclined surfaces between the first sliding block and the second sliding block and the driving part 343 and the vertical plane is 6°, and the angle between the inclined surfaces between the third sliding block and the driving part 343 and the vertical plane is 20°.

[0061] Based on the above embodiments, each of the pressure processing components 3 also includes at least one lateral positioning structure, and the lateral positioning structure includes a first matching block 51 and a first positioning block 52. The first matching block 51 is fixed to the side of the upper mold group 31, and the lower end surface of the first matching block 51 is concavely formed with a first groove. The first positioning block 52 is fixed to the side of the lower mold group 32, and the upper end of the first positioning block 52 is convexly formed to form a first protrusion, and the side surface of the first protrusion is tightly matched with the side wall surface of the first groove. Specifically, the end of the first protrusion and the bottom wall surface of the first groove do not contact, and there is a certain gap between the two. The lateral positioning structure mainly relies on the cooperation of the side for correction, that is, the cavity of the upper mold group 31 and the lower mold group 32 is completely buckled, and it is not easy to be padded due to external positioning, and it does not affect the hot pressing process while ensuring the guidance. Specifically, four lateral positioning structures are set in this embodiment, because the mold is generally set to be square, corresponding to four peripheral sides.

[0062] In this embodiment, based on the floating fit between the first mounting base 312 and the driving portion 343 , the first fitting block 51 and the first positioning block 52 are used for guiding, so that the mold fitting state is guided based on the lower mold assembly 32 .

[0063] Specifically, the middle of the lower die set 32 ​​of each pressure processing assembly 3 is connected to the base plate 1 through a center positioning pin, so that the position of each lower die set 32 ​​is ensured by precise matching of the shaft hole, thereby serving as a positioning reference for mold closing.

[0064] For further information, please refer to Figure 5 , the bottom plate 1 is provided with a plurality of second round holes distributed along the circumference of the bottom plate 1; in each of the pressure processing components 3, the lower mold group 32 includes a second mounting base 321, and the second mounting base 321 is provided with a plurality of second waist-shaped holes corresponding to the plurality of second circular holes, and the extension directions of two adjacent second waist-shaped holes intersect; the multi-hole pressure processing equipment 100 includes a plurality of second locating pins, and each of the second locating pins passes through the corresponding second circular hole and the corresponding second waist-shaped hole in turn. That is, when the second locating pin is installed, the shape of the hole corresponding to it on different templates may be different. In the actual production process, the temperature of the bottom plate 1 is lower than that of the second mounting base 321, so the expansion deformation is smaller, and the cooperation of the round hole and the cylindrical pin is conducive to precise cooperation, and the cooperation of the plurality of the second locating pins can play an anti-rotation effect. The design of the second waist-shaped hole can adapt to the expansion and deformation direction of the second mounting base 321. Even if the position of the waist-shaped hole is displaced from the center position of the template due to thermal expansion, the corresponding second positioning pin will not be squeezed and deformed due to the gap reserved in advance, thereby improving the matching effect of each part affected by temperature.

[0065] In addition, the bottom plate 1 and the second mounting base 321 are connected by a plurality of equal height screws to ensure the connection strength and limit the height position. The matching mode of the bottom plate 1 and the second mounting base 321 is consistent with the matching mode of the top plate 2 and the connecting seat 311. Since the parts have the same size, the same arrangement can be designed.

[0066] The upper mold assembly 31 is provided with a connecting seat 311, a first mounting base 312, an annular mounting frame for mounting the sliding part and other structures. The first matching block 51 is fixed on the annular mounting frame, and its upper part extends up and down, and can pass through the connection and the first mounting base 312 to play a role in positioning and guiding at the same time.

[0067] In order to ensure that the assembled circulation tooling can be positioned and matched with the lower die set 32, in one embodiment, the upper surface of the lower die set 32 ​​is provided with a plurality of positioning pins for matching with the positioning holes on the circulation tooling, and the plurality of positioning pins realize the horizontal and vertical limit of the horizontal plane to prevent the circulation tooling from shaking. In other embodiments, the upper surface of the lower die set 32 ​​is further provided with at least one proximity switch 322 for detecting the position of the circulation tooling. In this way, it is determined whether the current circulation tooling position is aligned and whether there is a circulation tooling on the lower die set 32. In this embodiment, positioning pins and proximity switches 322 are provided at the same time.

[0068] In the technical solution of the present invention, through the reasonable design of the waist-shaped hole and the round hole, the waist-shaped hole is precisely matched through the round hole, and the gap for expansion and deformation is reserved, which can adapt to the thermal expansion of the mold structure. The vertical and horizontal floating adjustment is realized by the matching of the connecting piece 331 and the equal height sleeve 332, thereby allowing a certain degree of adaptability between related components, and using multiple lower mold groups 32 as positioning references, the positions of multiple upper mold groups 31 are guided by the lateral matching of the first matching block 51 and the first positioning block 52, thereby ensuring the mold closing state, ensuring that under the influence of different thermal expansion and processing errors, multiple pressure processing components 3 can maintain good consistency when processing products, and ensure the yield of multi-hole production.
