Description

Technical Field

[0001] The present invention relates to the technical field of ceramic blank production equipment, and specifically, to a bottom mold removal and tilting mechanism and a high-pressure molding machine. Background Art

[0002] Ceramic blanks are usually produced by a ceramic high-pressure molding machine through a grouting method. Currently, since after each production of a blank by the high-pressure molding machine, it is necessary to drain the water in the mold. If the drainage time is insufficient, residual water will remain in the mold, which will in turn affect the yield rate of the formed blank; if the drainage time is too long, the waiting time for the next blank will become longer, which will in turn reduce the production efficiency of a large number of blanks. In addition, due to the limitation of the height of the customer's factory building, the height of the main engine power equipment of the high-pressure molding machine is limited. As a result, when taking the blank, the space between the blank and the bottom mold is not large, which makes it difficult to take the blank, and this also leads to low efficiency in the automatic production process of the blank.

[0003] Therefore, there is an urgent need for a new high-pressure molding machine. Summary of the Invention

[0004] The present invention provides a bottom mold removal and tilting mechanism and a high-pressure molding machine, which solve the problem of low production efficiency of blanks caused by the limited space between the bottom mold and the blank of the existing high-pressure molding machine and the long drainage time of the bottom mold.

[0005] The technical solution of the present invention is as follows: A bottom mold removal and tilting mechanism, comprising:

[0006] A base;

[0007] A guiding track, arranged on the base, the guiding track having a guiding surface, the guiding surface including a horizontal portion, a transition portion and an inclined portion, the transition portion being connected between the horizontal portion and the inclined portion;

[0008] A sliding plate, for installing and fixing the bottom mold and having a first end and a second end, the first end being in sliding contact with the guiding surface;

[0009] A driving assembly, arranged on the base and having a driving end moving in a first direction, the driving end being hinged to the second end;

[0010] Wherein, the first direction is parallel to the surface of the horizontal portion, and the first end realizes reciprocating movement on the guiding surface by means of the traction of the second end.

[0011] As a further technical solution, it further includes a supporting wheel, the supporting wheel being rotatably arranged on the side of the sliding plate and located on the first end.

[0012] As a further technical solution, the number of the guide rails and the number of the support wheels are both two and both are symmetrically arranged on the sides of the skateboard, and the guide rails and the support wheels are arranged in a one-to-one correspondence.

[0013] As a further technical solution, it also includes a limit pin, which is arranged on the base, and a limit groove is opened on the first end. After the slide plate moves, the limit pin penetrates into the limit groove.

[0014] As a further technical solution, the driving assembly includes:

[0015] A push member, disposed on the base and having a push end;

[0016] A transmission plate is slidably arranged on the base, and the transmission plate is connected to the pushing top end and is hinged with the second end portion.

[0017] As a further technical solution, the driving assembly further includes a guide rod, a guide hole is provided on the base, and the guide rod is connected to the transmission plate and penetrates into the guide hole.

[0018] As a further technical solution, the driving assembly further comprises an articulated seat, a part of which is connected to the second end portion, and another part of which is connected to the transmission plate.

[0019] As a further technical solution, the number of the guide rods and the number of the hinged seats are both two and both are symmetrically arranged on both sides of the pushing end of the pushing member.

[0020] The present invention also provides a high pressure forming machine, comprising any one of the above-mentioned bottom mold removal tilting mechanisms.

[0021] As a further technical solution, it also includes:

[0022] A frame, on which the bottom mold moving out tilting mechanism is arranged;

[0023] A mold clamping power assembly is arranged at the top of the frame and has a movable mold clamping power end;

[0024] A top mold, arranged on the mold clamping power end and located above the bottom mold moving out tilting mechanism;

[0025] The bottom mold is arranged on the bottom mold moving out tilting mechanism and is located below the top mold.

[0026] The working principle and beneficial effects of the bottom mold removal and tilting mechanism provided by the present invention are as follows: A bottom mold removal and tilting mechanism includes a base, a guiding track, a sliding plate, and a driving assembly. Among them, the guiding track is arranged on the base. The guiding track has a guiding surface. The sliding plate for installing and fixing the bottom mold can slide on the guiding surface under the push of the driving assembly. Along the moving direction of the sliding plate, the guiding surface is divided into a horizontal part, a transition part, and an inclined part. The horizontal part is parallel to the surface of the base (or the ground). The inclined part is an inclined plane, and the horizontal part is a horizontal plane. The transition part is connected between the horizontal part and the inclined part. Since the first end of the sliding plate is in sliding contact with the guiding surface, and the second end of the sliding plate moves along a first direction, and the first direction is parallel to the surface of the horizontal part, therefore, the second end of the sliding plate only moves in the horizontal direction, while the second end of the sliding plate can not only move along the first direction but also move in the vertical direction. Thus, for the sliding plate as a whole, the movement and flipping of the sliding plate are completed. Since the bottom mold is installed and fixed on the sliding plate, the bottom mold also moves and flips synchronously. For the high-pressure molding machine equipped with the bottom mold removal and tilting mechanism, after the bottom mold is removed and tilted, not only can the moisture in the mold be quickly discharged, but also the space occupied by the bottom mold in the frame is vacated after the bottom mold moves, so that the height of the top mold can be reduced. Since the blank is adsorbed on the top mold, the height of the blank can also be reduced accordingly. At this time, the blank taking manipulator (or operator) can conveniently take away the blank. And since a large amount of space is vacated after the bottom mold moves, the blank taking operation can not only improve the running speed but also greatly improve the safety of the blank, and ultimately improve the production efficiency of the blank.

[0035] The following will be combined with 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.

[0036] like Figures 1 to 4 As shown, this embodiment proposes a bottom mold moving out tilting mechanism 4, comprising:

[0037] Base 401;

[0038] A guide track 402 is provided on the base 401. The guide track 402 has a guide surface. The guide surface includes a horizontal portion, a transition portion and an inclined portion. The transition portion is connected between the horizontal portion and the inclined portion.

[0039] The slide plate 403 is used to install the fixed bottom mold and has a first end and a second end, and the first end is kept in contact with the guide surface in a sliding manner;

[0040] A driving assembly, disposed on the base 401 and having a driving end that moves in a first direction, the driving end being hinged to the second end;

[0041] The first direction is kept parallel to the surface of the horizontal portion, and the first end portion is pulled by the second end portion to achieve reciprocating movement on the guide surface.

[0042] In this embodiment, a bottom mold removal tilting mechanism 4 includes a base 401, a guide rail 402, a slide plate 403 and a driving assembly. The guide rail 402 is arranged on the base 401, and the guide rail 402 has a guide surface. The slide plate 403 for mounting and fixing the bottom mold can slide on the guide surface under the push of the driving assembly. Along the moving direction of the slide plate 403, the guide surface is divided into a horizontal part, a transition part and an inclined part. The horizontal part is parallel to the surface (or the ground) of the base 401, the inclined part is an inclined plane, the horizontal part is a horizontal plane, and the transition part is connected between the horizontal part and the inclined part. Since the first end of the slide plate 403 keeps contact with the guide surface in a sliding manner, and the second end of the slide plate 403 moves along the first direction, and the first direction is parallel to the surface of the horizontal part, the second end of the slide plate 403 only moves in the horizontal direction, and the second end of the slide plate 403 can not only move along the first direction, but also move in the vertical direction, so that for the slide plate 403 as a whole, the movement and flipping of the slide plate 403 are completed. Since the bottom mold is fixed on the slide plate 403, the bottom mold is also moved and turned synchronously. For the high-pressure forming machine equipped with the bottom mold removal and tilting mechanism 4, after the bottom mold is removed and turned, not only can the moisture in the mold be quickly discharged, but also the space occupied by the bottom mold in the frame 1 after the movement is avoided, thereby lowering the height of the top mold 3. Since the blank is adsorbed on the top mold 3, the height of the blank can also be lowered accordingly. At this time, the blank taking robot (or operator) can easily take the blank away, and since a large amount of space is vacated after the bottom mold is moved, the blank taking action can not only increase the operating speed, but also greatly improve the safety of the blank, and ultimately improve the efficiency of blank production.

[0043] It should be noted that when the bottom mold is moved out of the tilting mechanism 4 and arranged in the frame 1 of the high pressure forming machine, the bottom mold is arranged on the slide plate 403, and the slide plate 403 first moves horizontally to avoid the space originally occupied, and then turns over, so that the moisture in the bottom mold can be discharged. At the same time, since the space is avoided, the top mold 3 and the blank can be lowered. Therefore, the guide surface of the guide track 402 is arranged as a connection mode of the horizontal part, the transition part and the tilting part.

[0044] Further, if Figures 3 to 4 As shown, this embodiment further includes a support wheel 404, which is rotatably disposed on the side of the slide plate 403 and located on the first end.

[0045] In this embodiment, in order to reduce the friction between the slide plate 403 and the guiding track 402, a wheel seat and a supporting wheel 404 are arranged on the slide plate 403. The supporting wheel 404 is rotatably arranged on the side surface of the slide plate 403, and the outer edge of the supporting wheel 404 is in contact with the guiding surface of the guiding track 402. The wheel seat is arranged on the first end of the slide plate 403, and the slide plate 403 is no longer in direct contact with the guiding track 402. Thus, the resistance between the slide plate 403 and the guiding track 402 is reduced in the form of rolling friction, not only reducing the wear between the slide plate 403 and the guiding track 402, but also improving the operating efficiency of the slide plate 403.

[0046] Furthermore, as Figures 3 to 4 shown, in this embodiment, it is proposed that both the guiding track 402 and the supporting wheel 404 are two and are symmetrically arranged on the side of the slide plate 403, and the guiding track 402 and the supporting wheel 404 are arranged in one-to-one correspondence.

[0047] In this embodiment, in order to improve the stability of the slide plate 403 during movement and flipping, both the guiding track 402 and the supporting wheel 404 are arranged as two, and the two guiding tracks 402 are symmetrically arranged on the side of the slide plate 403, and then the guiding track 402 and the supporting wheel 404 are in a one-to-one correspondence.

[0048] Furthermore, as Figures 3 to 4 shown, in this embodiment, it is proposed that a limit pin 405 is further included. The limit pin 405 is arranged on the base 401, and a limit groove is opened on the first end. After the slide plate 403 moves, the limit pin 405 penetrates into the limit groove.

[0049] In this embodiment, since the slide plate 403 needs to continuously cycle in the states of "forward movement - forward flipping - reverse flipping - reverse movement", during reverse movement, in order to prevent the supporting wheel 404 from falling off the guiding track 402 and to move the bottom die to a specified position, a limit pin 405 is arranged on the base 401, and a limit groove is opened on the first end of the slide plate 403. When the limit pin 405 contacts the limit groove, the driving assembly stops driving the slide plate 403. Thus, it can ensure that the bottom die is located at the specified position in the high-pressure molding machine and can be smoothly combined with the top die 3 during the next mold closing.

[0050] Furthermore, as Figures 3 to 4 shown, in this embodiment, it is proposed that the driving assembly includes:

[0051] A pushing member 406, which is arranged on the base 401 and has a pushing end;

[0052] A transmission plate 407, which is slidably arranged on the base 401, and the transmission plate 407 is connected to the pushing end and is hinged to the second end.

[0053] In this embodiment, in order to reduce the overall manufacturing cost and service life of the bottom mold removal tilting mechanism 4, the driving component is selected to be a combination of a push-out member 406 and a transmission plate 407. The push-out member 406 is a common hydraulic cylinder. The hydraulic drive system required by the hydraulic cylinder is derived from the hydraulic drive system of the high-pressure molding machine. The hydraulic cylinder is arranged on the base 401 and the push-out end is connected to the transmission plate 407. The transmission plate 407 is slidably arranged on the base 401, and the transmission plate 407 is hinged to the second end of the slide plate 403.

[0054] Further, if Figures 3 to 4 As shown, this embodiment proposes that the driving assembly further includes a guide rod 408 , a guide hole is opened on the base 401 , and the guide rod 408 is connected to the transmission plate 407 and penetrates into the guide hole.

[0055] In this embodiment, in order to improve the stability of the transmission plate 407 during movement, the driving assembly further includes a guide rod 408. A guide hole is provided on the base 401, and the guide rod 408 is inserted into the guide hole. The axis of the guide hole is arranged along the reciprocating linear movement direction of the transmission plate 407. Grease is applied between the guide hole and the guide rod 408 to reduce the friction between the guide rod 408 and the guide hole.

[0056] Further, if Figures 3 to 4 As shown, this embodiment proposes that the driving assembly also includes an articulated seat 409 , a part of the articulated seat 409 is connected to the second end, and the other part is connected to the transmission plate 407 .

[0057] In this embodiment, in order to achieve a stable hinged relationship between the slide plate 403 and the transmission plate 407 , the drive assembly further includes an articulated seat 409 , a portion of which is connected to the second end of the slide plate 403 , and another portion of which is connected to the transmission plate 407 .

[0058] Further, if Figures 3 to 4 As shown, this embodiment proposes that there are two guide rods 408 and two hinge seats 409 symmetrically arranged on both sides of the pushing end of the pushing member 406 .

[0059] In this embodiment, in order to enable the driving assembly to stably transmit power to the slide plate 403, the guide rods 408 and the hinged seats 409 are each provided in the form of two, and the ejector member 406 is provided in the form of one, and the ejector member 406 is located between the two guide rods 408 and the two hinged seats 409, and the two hinged seats 409 are located between the two guide rods 408.

[0060] like Figures 1 to 2 As shown, the present invention also provides a high pressure forming machine, comprising a bottom mold removal tilting mechanism 4 of any one of the above items, and further comprising:

[0061] Frame 1, and a bottom die removal and tilting mechanism 4 is arranged on the frame 1;

[0062] A mold clamping power assembly 2, which is arranged at the top of the frame 1 and has a movable mold clamping power end;

[0063] A top die 3, which is arranged on the mold clamping power end and is located above the bottom die removal and tilting mechanism 4;

[0064] A bottom die 5, which is arranged on the bottom die removal and tilting mechanism 4 and is located below the top die 3.

[0065] In this embodiment, the high-pressure molding machine includes a frame 1, a mold clamping power assembly 2, a top die 3, and a bottom die removal and tilting mechanism 4. Among them, the mold clamping power assembly 2 and the bottom die removal and tilting mechanism 4 are both arranged on the frame 1, the top die 3 is arranged on the mold clamping power end of the mold clamping power assembly 2, the bottom die is located on a slide plate 403 inside the bottom die removal and tilting mechanism 4, the top die 3 is located above the bottom die. During mold clamping, the top die 3 contacts and clamps with the bottom die under the drive of the mold clamping power end, then slurry is injected to form a blank in the mold, then the top die 3 separates from the bottom die together with the blank, then the bottom die is pushed by the bottom die removal and tilting mechanism 4, first moves out of the original occupied space inside the frame 1, and then tilts to pour out the water in the bottom die, and then the vacated space can enable the blank taking manipulator to smoothly and safely take away the blank.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
