Description

Technical Field

[0001] The invention relates to the technical field of toilet production equipment, and in particular to a hydraulic toilet machine assembly. Background Art

[0002] At present, in the production of toilet blanks, the quality of the blank mold directly affects the quality of the finished blank. Due to its large size and heavy weight, the blank mold has poor operability in the mold opening and closing operations, especially the mold removal operability is poor. In addition, the mold opening and closing operations are performed manually, which not only consumes a lot of manual labor, but also has low production efficiency. The accuracy of manual operation cannot be guaranteed, and the rate of defective products is high, which greatly affects the economic benefits of production. In response to this problem, the applicant proposed a grouting toilet mold (application number CN201910360297.5) that can accurately and quickly close and open the mold. The mold structure design is flexible and compact. Compared with traditional technologies, the operability of mold opening and closing has been greatly improved. However, in the mold closing operation, the alignment and snap-fitting operation still has room for improvement in practice. In view of this, the applicant of this case, through further in-depth research, proposed an upgraded version of the toilet machine assembly production equipment, and this case was thus generated.

[0035] The case is further described in detail below in conjunction with specific implementation methods.

[0036] This case involves a hydraulic toilet machine assembly, such as Figure 1-6As shown in the figure, it includes a mold frame 200, a mold assembly 300 and a hydraulic assembly 400 installed on the mold frame 200. In order to realize the high-pressure grouting operation of the mold assembly 300, the mold frame 200 and the mold assembly 300 and the hydraulic assembly 400 thereon are integrally designed to be tiltable at an angle. Specifically, the assembly further includes a base 100. The mold frame 200 is movably suspended on the base 100 through its upper end. An oscillating hydraulic cylinder 11 is obliquely arranged between the bottom of the mold frame 200 and the bottom of the base 100. By operating the telescopic movement of the oscillating hydraulic cylinder 11, the inclination angle change of the mold assembly 300 can be flexibly controlled.

[0037] The main innovative technology of this case lies in the novel design and ingenious cooperation of the mold assembly 300 and the hydraulic assembly 400. The mold assembly 300 includes a left side plate 31, a right side plate 32, a rear side plate 33, an upper plate 34 and a lower plate 35. Both the left side plate 31 and the right side plate 32 are in an L-shaped structure. The left side plate 31 and the right side plate 32 are closed in a left-right manner with one side in a flat docking mode, and the closed mold forms a "冂" shape. The rear side plate 33 is flatly joined between the left side plate 31 and the right side plate 32 to form a square frame structure. The upper plate 34 and the lower plate 35 are respectively arranged on the top surface and the bottom surface of the square frame structure in a plane contact manner. The characteristic of the mold closing contact of each plate of the mold assembly 300 is that they all adopt plane fitting contact (see P shown in Figure 6 .

[0038] The hydraulic assembly 400 includes a left hydraulic mechanism 41, a right hydraulic mechanism, a rear hydraulic mechanism 43, an upper hydraulic mechanism 44 and a lower hydraulic mechanism 45. The left side plate 31 and the right side plate 32 are tightly closed left and right through the relative action of the left hydraulic mechanism 41 and the right hydraulic mechanism 42. The rear side plate 33 realizes the tight closing of the square frame structure through the rear hydraulic mechanism 43. The upper plate 34 and the lower plate 35 respectively realize the tight closing with the square frame structure through the upper hydraulic mechanism 44 and the lower hydraulic mechanism 45.

[0039] In the process of using the mold to produce product blanks, the performance of mold opening and closing directly affects product quality and production efficiency. The performance of mold opening and closing is mainly reflected in the operating performance of mold opening operation and mold closing operation. In mold closing, in order to ensure accurate alignment and fitting between each template, the current common method is to use a mutually limiting structure (such as a concave-convex step structure) to ensure alignment. However, due to the existence of this limiting structure, it is required to be very accurate in alignment during mold closing operation. And because there will inevitably be a certain error in mechanical displacement control, the limiting structure will instead affect the effectiveness of mold closing operation, and problems such as alignment deviation and failure to buckle are likely to occur, ultimately greatly affecting production efficiency. In mold parting, the limiting structure is also prone to jamming problems and has the defect of difficult demolding.

[0040] The mold assembly 300 of this case adopts a reverse idea. The contact method between the splicing plates of the mold is plane contact, and the assembly tightness of each plate is achieved by hydraulic means through the hydraulic assembly. In this way, simple mold opening and closing operations can be achieved by simply controlling the hydraulic assembly. Not only is the tightness of the mold guaranteed, but the problem of precise alignment and fastening between the plates is also cleverly avoided during mold closing. The operation is very simple and quick, and there will be no jamming problem during the demolding operation. It should be noted here that the plane contact in this case must ensure the consistency of the cavity structure after the mold is closed, which is related to the splicing design of the various plates of the mold assembly in this case. This case adopts the splicing mode of "double L-type-square frame structure-upper and lower pressing". In this way, even if the left plate, right plate and rear plate of the square frame structure have slight upper and lower deviations, they can be corrected by upper and lower relative pressing. Since the plane contact design has a certain surface width, the left and right deviations of the rear plate relative to the double L-type, and the horizontal deviations of the upper and lower plates relative to the square frame structure can be cleverly resolved, and will not affect the consistency of the constructed cavity structure. This greatly reduces the requirements for the control accuracy of the opening and closing operations, and ultimately ensures effective and efficient opening and closing operations.

[0041] In the hydraulic assembly 400 of this case, due to the innovative design of the planar contact structure, according to the structural characteristics of the mold assembly 300, the performance of the left hydraulic mechanism 41, the right hydraulic mechanism and the rear hydraulic mechanism 43 in the corresponding hydraulic assembly 400 is very critical. Here, the following particularly proposes a preferred solution for the design of the left hydraulic mechanism 41, the right hydraulic mechanism and the rear hydraulic mechanism 43.

[0042] The left side plate 31 and the right side plate 32 are symmetrically designed, and the corresponding left hydraulic mechanism 41 and the right hydraulic mechanism are the same mechanism with symmetrical design. The left hydraulic mechanism 41 is taken as an example below (the right hydraulic mechanism is the same), which includes a shift hydraulic cylinder unit 411 and four groups of tightening hydraulic cylinder units 412. The shift hydraulic cylinder unit 411 is connected between the left side plate 31 and the mold frame 200, and is correspondingly arranged at the center position of the left side plate 31. In this way, through the telescopic action of the shift hydraulic cylinder unit 411, the left side plate 31 can be driven to shift horizontally, and the left side plate 31 and the right side plate 32 are horizontally close to each other or separated, so as to realize the opening and closing operation of the two. The four groups of tightening hydraulic cylinder units 412 are respectively arranged at the four corners of the left side plate 31 to appropriately tighten the four corners of the left side plate 31. When the left side plate 31 and the right side plate 32 are brought together for mold closing by their respective shifting hydraulic cylinder units, the four corners are appropriately tightened by their respective four sets of tightening hydraulic cylinder units, thus ensuring that the basic module part composed of the left side plate 31 and the right side plate 32 is tightly molded, which is the basic guarantee for the mold closing performance of the entire mold.

[0043] In the preferred solution, taking the left hydraulic mechanism 41 as an example (the right hydraulic mechanism is the same), the four groups of top-tightening hydraulic cylinder units 412 are arranged in pairs, wherein the two groups on the upper side are arranged on the corresponding side of the upper plate 34, and the two groups on the lower side are arranged on the corresponding side of the lower plate 35. Such a design is conducive to the simple and compact arrangement of the overall structure on the one hand, and on the other hand, the four groups of top-tightening hydraulic cylinder units 412 are synchronously displaced with the upper and lower plates, that is, the upper and lower offset displacements relative to the left plate 31 and the right plate 32 ensure that when the mold is closed, the top-tightening operation is performed after the upper and lower plates are pressed together on the square frame structure, thereby improving the overall stability and tightness of the mold; at the same time, it is ensured that when the mold is separated, the top-tightening hydraulic cylinder units are staggered and displaced to avoid possible influence on the operation of the displacement hydraulic cylinder units, and the action stroke of the top-tightening hydraulic cylinder units can also be reduced.

[0044] Preferably, in order to facilitate the horizontal displacement of the left plate 31 and the right plate 32 by the shift hydraulic cylinder unit, a guide unit 413 is provided on both sides of the shift hydraulic cylinder unit 411, taking the left hydraulic mechanism 41 as an example (the same applies to the right hydraulic mechanism). The guide unit 413 can be specifically in the form of a guide column and guide sleeve structure.

[0045] In the preferred embodiment, the rear hydraulic mechanism 43 adopts a hydraulic locking mechanism, and the locking method makes the entire square frame structure more compact, stable and reliable. The hydraulic locking mechanism includes a buckle 431, a slot 432 and a tightening hydraulic cylinder 433. The buckle 431 is arranged at the rear end of the left side plate 31 and the right side plate 32, and the buckle 431 is arranged to extend backward from the left side plate 31 / right side plate 32. The slot 432 is arranged on both sides of the rear side plate 33, and is arranged one-to-one with the buckle 431. When the rear side plate 43 approaches the left side plate 31 / right side plate 32 for mold closing, each buckle 431 can pass through the corresponding slot 432. The tightening hydraulic cylinder 433 is arranged one-to-one beside the slot 432 to hydraulically tighten the buckle 431 passing through the slot 432, so as to realize the hydraulic locking effect of the rear side plate 33 and the left side plate 31 and the right side plate 32.

[0046] In the preferred embodiment, in order to improve the locking strength, the buckles 431 on the left side plate 31 and the right side plate 32 are each provided with two upper and lower groups, and the slots 432 on both sides of the rear side plate 33 are respectively provided with two upper and lower groups. In this way, a total of four groups are locked up and down to ensure the overall tightness of the four-square frame structure formed by the mold.

[0047] In a preferred embodiment, the buckle 431 is engaged with the slot 432 by means of a hydraulic cylinder 433, and adopts an inverted hook method. Specifically, the buckle 431 is an inverted hook buckle, and has a hook head, which passes through the slot 432, and is held by the hydraulic cylinder 433 to achieve mutual locking with the slot 432. In addition, in order to enable the buckle 431 to automatically return to its original position when not tightened, so as to facilitate the smooth separation of the rear side plate 33 during mold separation, the buckle 431 is movably pivoted on the left side plate 31 / right side plate 32, and a reset spring 434 is provided at the front end of the buckle. Under the action of the reset spring 434, the buckle 431 automatically returns to its original position when not tightened.

[0048] In a preferred embodiment, when the buckles 431 are arranged in two groups, the hook parts of the buckles 431 in the two groups are arranged opposite to each other. This makes the locking more stable and reliable, and avoids the problem of disengagement. In addition, the convex surface of the hook part of the buckle 431 is designed as an arc surface 4311, and the limiting part of the slot 432 that cooperates with the hook part is an inclined surface 4321. Such a design facilitates automatic disengagement and avoids the problem of the buckle 431 being stuck.

[0049] The preferred solution is that the upper hydraulic mechanism 44 and the lower hydraulic mechanism 45 corresponding to the upper plate 34 and the lower plate 35, in order to improve the stability and reliability of the lifting action during the opening and closing operation, the design point 1 is to design the mold frame 200 with an upper machine base 21, a lower machine base 22 and a column group 23, and the upper machine base 21 and the lower machine base 22 are connected in an integral manner up and down through the column group 23, and the upper plate 34 and the lower plate 35 are respectively fixedly installed on the upper plate seat 342 and the lower plate seat 352, and the four corners of the upper plate seat 342 and the lower plate seat 352 are provided with seat hole grooves, and the seat hole grooves are movably mounted on the column group 23, so that the smooth lifting action of the upper plate seat 342 and the lower plate seat 352 is guaranteed by the guidance of the column group 23. Design point 2, guide units 441 and 451 are also provided on both sides of the upper hydraulic mechanism 44 and the lower hydraulic mechanism 45, respectively, and the lifting stability is further improved by the guide units 441 and 451.

[0050] Preferably, in order to improve the supporting strength of the lower plate seat 352, a tightening mechanism 5 is provided between the lower plate seat 352 and the lower machine base 22. The tightening mechanism 5 is preferably arranged on the lower machine base 22 to tighten the bottom of the guide unit 451 that rises with the lower plate seat 352 during mold closing.

[0051] Preferably, the rear side plate 33 is arranged on the mold frame 100 through the translation and lifting mechanism 6, and the translation and lifting mechanism 6 realizes the two-dimensional movement of translation and lifting of the rear side plate 33, thereby facilitating the opening and closing operations of the mold.

[0052] In the preferred embodiment, the mold assembly 300 is a heavy and large mold. In order to strengthen the structural strength of each plate, each plate is embedded with a steel bar structure, wherein the steel bars of the upper plate 34, the lower plate 35 and the rear side plate 33 are arranged in parallel or cross-arranged. In a specific embodiment, the steel bars 341 and 351 of the upper plate 34 and the lower plate 35 are arranged cross-arranged, and the steel bars of the rear side plate 33 are arranged vertically in parallel. The steel bars of the left plate 31 and the right plate 32 are adapted to their L-shaped structural arrangement.

[0053] The preferred solution is to improve the automatic flow operation of the hydraulic toilet machine assembly of this case, such as Figure 7 As shown, a lifting and transfer trolley 700 and a blank conveying line 800 are also provided at the rear of the base 100, and the lifting and transfer trolley 700 is supported between the base 100 and the blank conveying line 800. In operation, after the blank is formed, the rear side plate 33, the upper plate 34 and the lower plate 35 are evenly separated from the mold, and the blank is clamped by the left and right side plates. The receiving plate of the lifting and transfer trolley 700 rises under the action of the lifting unit, and extends horizontally to the bottom of the blank under the action of the translation unit. The left and right side plates are separated from the mold, and the blank is supported by the receiving plate; after that, the receiving plate returns, exits and descends, and the receiving plate is turned 90 degrees under the action of the turning unit, so that the blank on it is turned 90 degrees to the blank conveying line 800, and finally the blank conveying line 800 automatically conveys it out.
