Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to an eco-brick production mold. Background Art

[0002] In urban construction, permeable ecological bricks are used to alleviate the problem that surface precipitation cannot penetrate into the ground and impermeable ground isolates the exchange of water vapor and heat energy.

[0003] To improve the efficiency of eco-brick production, existing technologies use molds for rapid processing. Typically, the material is placed in a lower mold, and a drive mechanism (such as a hydraulic mechanism) moves the upper mold toward the lower mold. The upper and lower molds fit together to form the brick. Once the brick is fully formed, the upper and lower molds are separated, and the brick can be removed from the mold cavity.

[0004] To facilitate demolding, the inner wall of the cavity is usually drafted to a certain angle, forming a trapezoidal structure with a large opening and a small bottom. This treatment method can reduce product damage; however, this method is only applicable to products with a large draft angle. When the product has a small draft angle or even no draft angle, the side walls will be worn when the product is ejected from the mold cavity, and even the corners may break due to extrusion force, resulting in an increase in the failure rate and affecting costs. Utility Model Content

[0005] In order to relatively reduce the technical problem of damage that is easy to occur when demoulding ecological bricks and improve the qualified rate of produced bricks, the present application provides an ecological brick production mold.

[0006] This application provides an eco-brick production mold, which adopts the following technical solution:

[0007] A mold for producing ecological bricks, comprising a mold frame, an upper mold and a lower mold installed on the mold frame, the lower mold comprising a bottom plate and four side plates surrounding and respectively abutting against the four sides of the bottom plate, the middle ends of the side plates abutting against the bottom plate, and the bottom plate and the four side plates form a mold cavity that cooperates with the upper mold and is open upward, at least four push-pull plates with their free ends inclined upward toward the mold cavity are fixedly connected to the lower side of the bottom plate, an inclined groove for the push-pull plates to slide freely is provided on the lower side of each side plate, the lower end of each side plate is horizontally slidably connected to a side support plate with one end fixed to the mold frame, and the mold frame is also provided with a vertical drive mechanism whose drive end is transmission-connected to the bottom plate.

[0008] By adopting the above technical solution, during mold opening, the bottom plate is driven by the vertical driving mechanism to move towards the upper mold, and the free end of the push-pull plate slides in the inclined groove at the same time. Under the action of at least four push-pull plates, the opposite side plates slide horizontally away from each other on the side support plates. As the molded product is lifted by the bottom plate and removed from the mold cavity, the four side plates move away from the product at the same time, thereby relatively reducing the technical problem that the ecological bricks are prone to damage during demolding and improving the qualification rate of the produced bricks.

[0009] Optionally, the push-pull plate includes a bent section fixedly connected to one end of the bottom plate and an inclined section fixedly connected to the other end of the bent section. The inclined section is inclined and the other end is adapted to and slidably connected to the inclined groove.

[0010] By adopting the above technical solution, through the connection of the bent section, when the bottom plate slides, the inclined section can be driven to slide in the inclined groove, thereby driving the side plate to move horizontally.

[0011] Optionally, a section of the bent section away from the bottom plate abuts against the mold frame.

[0012] By adopting the above technical solution, during processing, the bent sections of multiple push-pull plates form a supporting effect on the bottom plate to maintain balance.

[0013] Optionally, at least two side support plates horizontally slidably connected to the same side plate are provided and are evenly distributed.

[0014] By adopting the above technical solution, multiple side support plates are used to maintain the supporting balance of the side plates and ensure the qualification of the product.

[0015] Optionally, sliding holes are formed at the lower ends of the side plates, and the other ends of the side support plates are adapted to and horizontally slidably connected to the sliding holes.

[0016] By adopting the above technical solution, the other ends of the side support plates are inserted into the sliding holes to form a support for the side plates.

[0017] Optionally, the corresponding sliding holes and the push-pull plates are located in different vertical planes.

[0018] By adopting the above technical solution, to prevent the push-pull plates and the side support plates from colliding.

[0019] Optionally, the side support plate includes a vertical section fixedly connected to one end of the mold frame and a horizontal section fixedly connected to the other end of the vertical section. The other end of the horizontal section is horizontally slidably connected to the sliding hole.

[0020] By adopting the above technical solution, the horizontal section is used to form a supporting effect on the side plate to maintain the vertical state of the side plate.

[0021] Optionally, slots are formed in two opposite side plates, and insertion blocks adapted to and inserted into the slots are formed on the other two side plates. Moreover, insertion holes are formed at the tops of the two opposite side plates and the insertion blocks at the same time, and insertion rods are inserted into the connected insertion holes at the same time.

[0022] By adopting the above technical solution, before adding raw materials into the mold cavity of the lower mold, the insertion rods are inserted into the same insertion holes to connect two adjacent side plates together, preventing the lower mold from bulging due to mold clamping.

[0023] Optionally, the slots do not penetrate the inner sides of the side plates.

[0024] By adopting the above technical solution, the smoothness of the inner sides of the side plates is ensured, guaranteeing the smooth molding of the product.

[0025] Optionally, a plurality of positioning holes are formed in the upper mold. One end of the insertion rod is inserted into the insertion hole, and the other end extends into the corresponding positioning hole.

[0026] By adopting the above technical solution, when the mold is clamped, the insertion rods entering the positioning holes can make the mold fit more tightly and also ensure the stability of the mold.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] By forming inclined grooves on each side plate and connecting a plurality of push-pull plates with free ends respectively adapted to and slidably connected to the inclined grooves on the bottom plate, during the movement of the bottom plate along the line, the free ends of the push-pull plates slide and connect to the inclined grooves, driving the side plates to horizontally slide and connect to the side support plates, realizing the relative separation of the side plates and the bottom plate, thereby preventing the product from being worn and improving the qualified rate of the product;

[0029] While the side plates and the bottom plate are relatively separated, the bottom plate lifts and pushes the product out of the cavity, facilitating the removal of the product;

[0030] The free ends of the push-pull plates are always slidably connected to the inclined grooves, ensuring that the side plates abut against the bottom plate during the mold clamping process and reducing the probability of mold bulging;

[0031] By arranging insertion rods to connect two adjacent side plates to prevent mold bulging; and the top ends of the insertion rods extend into the positioning holes, realizing the guiding function of the upper mold when clamping to the lower mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following further describes the present utility model in conjunction with the attached drawings. Figures 1-3 The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are some but not all of the embodiments of the present utility model.

[0045] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0046] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "mounted / connected," and "connected" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this invention can be understood according to specific circumstances.

[0047] Reference Figures 1 to 3 , an ecological brick production mold includes a mold frame, an upper mold 4 and a lower mold 5 installed on the mold frame, the lower mold 5 includes a bottom plate 51 and four side plates 52 surrounding and respectively abutting against the four sides of the bottom plate 51, the middle ends of the side plates 52 abut against the bottom plate 51, and the bottom plate 51 and the four side plates 52 form a mold cavity that matches the upper mold 4 and opens upward, and at least four push-pull plates 6 with their free ends inclined upward toward the mold cavity are fixedly connected to the lower side of the bottom plate 51, and an inclined groove 521 for the push-pull plate 6 to slide freely is opened on the lower side of each side plate 52, and the lower end of each side plate 52 is horizontally slidably connected to a side support plate 7 fixed to the mold frame at one end, and the mold frame is also provided with a vertical drive mechanism 8 whose drive end is transmission-connected to the bottom plate 51.

[0048] Among them, the bottom plate 51 and the side plate 52 are both rectangular plates, and the inner side surface of the side plate 52 is a slope to facilitate demoulding; the outer sides of the bottom plate 51 are matching slopes to ensure that the bottom plate 51 and the side plate 52 fit precisely.

[0049] The free end of the push-pull plate 6 refers to the end away from the bottom plate 51. Correspondingly, the end fixedly connected to the bottom plate 51 is a fixed connection. Furthermore, the free end of the push-pull plate 6 is longer than the depth of the inclined groove 521. This prevents the free end of the push-pull plate 6 from slipping out of the inclined groove 521 when the bottom plate 51 and the side plate 52 abut against each other to form the mold cavity. This creates a pulling effect on the side plate 52 through the push-pull plate 6, preventing the bottom plate 51 and the side plate 52 from moving away from each other during mold closing, which could cause mold expansion.

[0050] Based on the above embodiment, the mold frame comprises a workbench 1, multiple hydraulic telescopic rods 2 mounted on the workbench 1, and an upper mold base 3 connected to the piston ends (the upper ends shown in the figure) of the multiple hydraulic telescopic rods 2. An upper mold base 4 is bolted to the upper mold base 3. A lower mold base 5 is mounted on the workbench 1, directly below the upper mold base 4, forming a mold cavity that fits the upper mold base 4 and opens upward. A vertical drive mechanism 8 is located within the workbench 1, which is a box-shaped structure with a space within.

[0051] In practical applications, the control switches of the electronic devices of this device are concentrated in one place, which is convenient for operators to use. During operation, first put the materials for making permeable bricks into the lower mold 5, start the hydraulic telescopic rod 2, move the upper mold 4 downward, so that the upper mold 4 fits with the lower mold 5. After the permeable brick is completely formed, start the hydraulic telescopic rod 2 again to lift the upper mold 4 and perform mold opening. When opening the mold, the vertical driving mechanism 8 drives the bottom plate 51 to move towards the upper mold 4. The free end of the push-pull plate 6 slides in the inclined groove 521 at the same time. Under the action of at least four push-pull plates 6, the opposite side plates 52 slide horizontally away from each other on the side support plates 7. As the mold opening finished product is lifted by the bottom plate 51 and moved out of the mold cavity, the four side plates 52 move away from the product at the same time, thus relatively reducing the technical problem of easy damage during the demolding of ecological bricks and improving the qualified rate of the produced bricks. At the same time, when opening the mold, the noise generated by the friction between the product and the inner wall of the lower mold 5 is reduced.

[0052] As one of the specific solutions of the above embodiment, the vertical driving mechanism 8 includes a fixing plate 81 fixed to the bottom of the workbench 1, a plurality of return springs 82 with their lower ends fixedly connected to the upper side of the fixing plate 81, a lifting plate 83 arranged horizontally and fixedly connected to the upper ends of the plurality of return springs 82 at the same time, a limit bolt 84 slidably connected horizontally to the workbench 1, and a push rod 85 with its lower end fixedly connected to the upper side of the lifting plate 83; one end of the limit bolt 84 is located outside the workbench 1, and the other end extends into and is slidably connected to the chute at one end of the lifting plate 83; the upper end of the push rod 85 is fixedly connected to the lower end of the bottom plate 51.

[0053] When opening the mold, pull out the limit bolt 84, so that the return spring 82 bounces upward, so that the lifting plate 83 moves upward, so that the push rod 85 drives the bottom plate 51 to move upward, so as to eject the formed permeable brick out of the lower mold 5, realizing automatic demolding, reducing manual labor and improving work efficiency. When placing materials into the lower mold 5, apply a downward force to the bottom plate 51, and the bottom plate 51 can be moved downward to compress the return spring 82. When the bottom plate 51 moves downward to the lower limit position, the other end of the limit bolt 84 is horizontally opposite to the chute at one end of the lifting plate 83, and the limit bolt 84 can be inserted into the chute.

[0054] Among them, one indication that the bottom plate 51 moves downward to the lower limit position is: usually, the inner side surface of the side plate 52 is an inclined surface to facilitate product demolding, that is, the four outer side surfaces of the bottom plate 51 are inclined surfaces. When the bottom plate 51 descends until its outside completely abuts against the side plate 52, it means that it has moved to the lowest limit position.

[0055] Among them, a through hole is opened on the upper side of the workbench 1 for the push rod 85 to pass through.

[0056] Among them, the upper end of the push rod 85 is fixedly connected to the central position of the lower end of the bottom plate 51 to ensure balanced force.

[0057] A buffer pad is fixedly connected to the lifting plate 83 to slow down the upward movement, making demoulding more stable and safe.

[0058] As a second specific solution of the above embodiment, the vertical drive mechanism 8 can be a linear drive mechanism such as a ball screw transmission mechanism, a synchronous belt transmission, an electric push rod, an electric cylinder, a cam mechanism, a cylinder mechanism, and a linear motor drive. The drive end of the linear drive mechanism can be connected to the center position of the lower end of the base plate 51.

[0059] Reference Figure 2 and Figure 3 The push-pull plate 6 includes a bent section 61 fixedly connected to the bottom plate 51 at one end and an inclined section 62 fixedly connected to the other end of the bent section 61 at one end. The inclined section 62 is inclined and the other end is adapted and slidably connected to the inclined groove 521. Through the connection of the bent section 61, when the bottom plate 51 slides, the inclined section 62 can be driven to slide in the inclined groove 521, thereby driving the side plate 52 to move horizontally.

[0060] The bent section 61 is L-shaped, with one end fixedly connected to the underside of the base plate 51 and the other end extending laterally away from the ejector pin 85. The inclined section 62 is tilted, with one end (shown as the lower end) fixedly connected to the other end of the bent section 61 and the other end extending obliquely toward the mold cavity, forming a free end.

[0061] Moreover, the free end length of the inclined section 62 is greater than the groove depth of the inclined groove 521, so that when the bottom plate 51 and the side plate 52 abut against each other to form a mold cavity, the free end of the inclined section 62 will still not fall out of the inclined groove 521, thereby forming a pulling effect on the side plate 52 through the push-pull plate 6, preventing the bottom plate 51 and the side plate 52 from moving away from each other when the mold is closed, causing mold expansion.

[0062] The bending section 61 away from the bottom plate 51 is in contact with the workbench 1 of the mold frame. During processing, the bending sections 61 of the plurality of push-pull plates 6 form a support for the bottom plate 51 to maintain balance.

[0063] The second indication that the bottom plate 51 has moved downward to the lower limit position is: when the mold is closed, when the bottom plate 51 descends until the bending section 61 abuts against the upper side of the workbench 1 , it means that the bottom plate 51 has moved to the lowest limit position.

[0064] At least two side support plates 7 are provided which are horizontally slidably connected to the same side plate 52 and are evenly spaced apart, so that the support balance of the side plate 52 can be maintained by using multiple side support plates 7 to ensure the quality of the product.

[0065] On the basis of the above embodiment, at least two push-pull plates 6 are also provided in sliding connection with the same side plate 52 .

[0066] Reference Figure 2and Figure 3 At the lower ends of the side plates 52, sliding holes 522 with horizontally opening are formed through, and the other end of the side support plate 7 is adapted and horizontally slidably connected to the sliding hole 522, so as to insert the other end of the side support plate 7 into the sliding hole 522 to form a support for the side plate 52.

[0067] The corresponding sliding hole 522 and the push-pull plate 6 are located in different vertical planes to prevent the push-pull plate 6 and the side support plate 7 from colliding.

[0068] Wherein, the side support plate 7 includes a vertical section 71 fixedly connected to the mold base at one end and a horizontal section 72 fixedly connected to the other end of the vertical section 71 at one end. The other end of the horizontal section 72 is horizontally slidably connected to the sliding hole 522, and the horizontal section 72 is used to form a supporting effect on the side plate 52 to keep the side plate 52 in a vertical state.

[0069] Referring to Figure 2 and Figure 3 Among them, two opposite side plates 52 are provided with slots 523, and the other two side plates 52 are formed with insertion blocks 524 adapted to be inserted into the slots 523, and the tops of the two opposite side plates 52 and the insertion blocks 524 are simultaneously provided with insertion holes, and the connected insertion holes are simultaneously inserted with insertion rods 525. Before adding raw materials into the mold cavity of the lower mold 5, the insertion rods 525 are inserted into the same insertion holes to connect two adjacent side plates 52 together, further preventing the lower mold 5 from bulging due to mold clamping. When opening the mold, before lifting the bottom plate 51, the four insertion rods 525 are first pulled out.

[0070] Specifically, through holes communicating with the slots 523 are formed at the tops of both ends of the side plate 52, and through holes are also formed on the insertion block 524. After the insertion block 524 is inserted into the slot 523, the two through holes are communicated.

[0071] The slot 523 does not penetrate through the inner side of the side plate 52 to ensure the smoothness of the inner side of the side plate 52 and ensure the smooth molding of the product. Wherein, the inner side of the side plate 52 refers to the side of two opposite side plates 52 facing each other.

[0072] A plurality of positioning holes 41 are formed on the lower side of the upper mold 4. One end of the insertion rod 525 is inserted into the insertion hole, and the other end extends into the corresponding positioning hole 41. When clamping the mold, the insertion rod 525 entering the positioning hole 41 can make the mold fit more tightly and also ensure the stability of the mold.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
