Description

TECHNICAL FIELD

[0001] The present application relates to a prefabricated part forming die, in particular an energy-saving type highway drainage ditch concrete prefabricated part forming die assisting in labor-saving demolding. BACKGROUND

[0002] The energy-saving type highway drainage ditch concrete prefabricated part is a new type of prefabricated concrete product developed to meet the needs of green highway construction. It realizes energy saving and consumption reduction in the whole life cycle through material optimization, process innovation and structure design, and at the same time, it also takes into account high strength, durability and construction convenience. Compared with traditional concrete drainage ditches, the surface quality requirements of energy-saving type drainage ditch prefabricated parts show the characteristics of "more strict, more fine and more functional".

[0003] The common drainage ditch concrete prefabricated part forming die includes a bottom die, a cover die and a side die. By combining the bottom die, the cover die and the side die, a pouring cavity is formed to ensure the smooth progress of subsequent pouring production. The common bottom die and cover die are connected by bolts, which has high connection strength and good stability, and can reduce the probability of mold rising and mold explosion during pouring. However, due to the strong adhesion of concrete, even if the bolt connection between the bottom die and the cover die is immediately released during demolding, the formed drainage ditch prefabricated part is also difficult to separate from the bottom die and the cover die. When external force is applied to forcibly separate the cover die and the bottom die, the surface of the prefabricated part may be damaged.

[0004] The common energy-saving type highway drainage ditch concrete prefabricated part forming die adds an elastic module to the common drainage ditch concrete prefabricated part forming die. That is, during the closing process, the elastic module performs energy storage action. During the demolding process, the elastic module releases elastic force to assist in labor-saving demolding. The common elastic module includes a spring, which is arranged between the bottom die and the cover die. When the cover die is released from the limiting state, the spring releases elastic force to drive the cover die and the bottom die apart.

[0005] During the demolding process of the common energy-saving type highway drainage ditch concrete prefabricated part forming die, the spring will immediately release elastic force when the cover die is released from the limiting state. Generally, the stiffness coefficient of the spring is large (a too small stiffness coefficient will not be able to drive the cover die and the bottom die apart), so the instantaneous kinetic energy of the spring releasing elastic force is large, which makes the instantaneous peeling force between the concrete and the die large, which may cause stress concentration and lead to cracking or corner damage of the prefabricated part.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] In addition, elements in the present application can be referred to as "fixed" or "disposed" on another element, which can be directly on another element or can also exist with a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can also exist with a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0032] Please refer to Figures 1-11 In the embodiment of the present application, the energy-saving highway drainage ditch concrete prefabricated part forming mold for assisting in labor-saving demolding comprises a bottom mold 1, and a side mold 3 is fixedly installed on one side of the bottom mold 1; It also includes a cover mold 2; the bottom mold 1 is fixedly installed with symmetrically arranged positioning sleeves 4; the cover mold 2 is fixedly installed with a matching sleeve 13 which is slidingly fitted with the positioning sleeve 4; The mold closing piece is used to limit the matching sleeve 13 after the sliding connection of the matching sleeve 13 and the positioning sleeve 4, It also includes a demolding piece, which comprises a partition plate 7 and a telescopic column 10 slidingly arranged in the positioning sleeve 4. After the mold closing piece releases the limiting state of the matching sleeve 13, the partition plate 7 and the telescopic column 10 can alternately drive the matching sleeve 13 to move outward in the positioning sleeve 4.

[0033] In use, the bottom mold 1, the cover mold 2 and the side mold 3 cooperate with each other to form a cavity for pouring the energy-saving highway drainage ditch concrete prefabricated part.

[0034] Mold closing: apply external force to move the cover mold 2, so that the matching sleeve 13 is aligned with the positioning sleeve 4; then apply external force to make the cover mold 2 parallel to the bottom mold 1, so that the matching sleeve 13 is slidingly connected with the positioning sleeve 4, wherein the matching sleeve 13 will slide inward in the positioning sleeve 4; through the sliding cooperation of the positioning sleeve 4 and the matching sleeve 13, the positioning action of the cover mold 2 can be completed during mold closing, so as to avoid the misplacement of the cover mold 2 and the bottom mold 1, which leads to the reduction of the quality of the prefabricated part produced.

[0035] When the cover mold 2 and the bottom mold 1 complete the confrontation, external force is applied to drive the mold closing piece to act, so as to limit the matching sleeve 13 through the mold closing piece, thereby increasing the difficulty of separating the cover mold 2 and the bottom mold 1, avoiding the phenomenon of rising mold or even exploding mold during subsequent pouring of concrete; thereby ensuring that the drainage ditch concrete prefabricated part can be successfully produced.

[0036] And in the process of closing, the sliding fitting sleeve 13 can drive the partition plate 7 and the telescopic column 10 to move alternately, thereby storing energy for subsequent demolding member action.

[0037] Demolding: when the strength of the concrete in the cavity reaches the design requirement, an external force is applied to drive the closing member to act, thereby releasing the limiting state of the fitting sleeve 13; at this time, the partition plate 7 and the telescopic column 10 will alternately drive the fitting sleeve 13 to slide outward in the positioning sleeve 4 (energy storage release), thereby separating the cover mold 2 from the bottom mold 1 to complete the demolding action.

[0038] When the cover mold 2 and the bottom mold 1 are completed, the cover mold 2 is limited by the closing member, which can ensure the connection strength of the cover mold 2 and the bottom mold 1, and ensure the smooth production of the drainage ditch concrete prefabricated part; in the demolding process, after the closing member releases the limiting state, the cover mold 2 is driven away from the bottom mold 1 by the partition plate 7 and the telescopic column 10 alternately, which can effectively reduce the difficulty of demolding, and in the demolding process, no additional external force is needed to be applied vertically to the bottom mold 1 and the cover mold 2, which can effectively reduce the demolding cost (time cost, labor cost, etc.).

[0039] In another embodiment of the application, the closing member includes a connecting column 14 fixedly installed in the fitting sleeve 13, and a locking groove 1401 is formed in the connecting column 14; a connecting groove 401 is formed in the positioning sleeve 4 and is in sliding connection with the connecting column 14; and a rotating block 5 is rotatably installed on the positioning sleeve 4; and a locking assembly is fixedly installed on the rotating block 5 and cooperates with the locking groove 1401.

[0040] In another embodiment of the application, the locking assembly includes a first locking block 501, an inclined locking block 502 and a second locking block 503, wherein the two ends of the inclined locking block 502 are fixedly connected with the first locking block 501 and the second locking block 503 respectively; and the first locking block 501 and the second locking block 503 are both horizontally arranged; and the inclined locking block 502 is arranged obliquely.

[0041] In use, the closing member is closed: the fitting sleeve 13 slides inward in the positioning sleeve 4.

[0042] During the sliding process, the fitting sleeve 13 drives the connecting column 14 to move synchronously, and when the cover mold 2 and the bottom mold 1 are fitted, the connecting column 14 passes through the connecting groove 401 (part of the connecting column 14 is exposed at the bottom of the positioning sleeve 4), so that the locking groove 1401 can be exposed to the positioning sleeve 4.

[0043] Then the rotating block 5 is rotated by means of a tool, thereby driving the locking assembly to rotate synchronously, so that it is in abutting cooperation with the locking groove 1401.

[0044] When the locking assembly rotates, the horizontally arranged first locking block 501 enters the locking groove 1401 first, thereby guiding the inclined locking block 502 to enter the locking groove 1401; then the inclined locking block 502 rotates and is in contact with the groove wall of the locking groove 1401, thereby extruding the connecting column 14 (the inclined locking block 502 is arranged obliquely) and gradually increasing the length of the exposed positioning sleeve 4; when the inclined locking block 502 rotates to be separated from the locking groove 1401, the second locking block 503 enters the locking groove 1401, at this time, the bottom die 1 and the cover die 2 are completely attached; at this time, through the contact of the horizontally arranged second locking block 503 and the groove wall of the locking groove 1401, the difficulty of separating the bottom die 1 and the cover die 2 can be increased, thereby avoiding the problems of die expansion and die explosion.

[0045] When demolding, the rotating block 5 is reversely rotated by means of a tool, so that the locking assembly is completely separated from the locking groove 1401, and the limiting state of the cover die 2 is released.

[0046] In another embodiment of the present application, the demolding member further comprises a fixed sleeve 6 fixedly installed in the positioning sleeve 4, the fixed sleeve 6 is slidably embedded with the telescopic column 10; a sliding groove 601 is arranged in the fixed sleeve 6; a sliding block 701 slidably embedded with the sliding groove 601 is fixedly installed on the partition plate 7; a first spring 8 is arranged in the fixed sleeve 6; the two ends of the first spring 8 are in contact with the partition plate 7 and the positioning sleeve 4 respectively; a protruding column 1301 capable of being in contact with the sliding block 701 is fixedly installed in the matching sleeve 13.

[0047] In the use of the embodiment in which all the features described in the present application are combined, during the die closing process, the matching sleeve 13 slides inward in the positioning sleeve 4, thereby driving the protruding column 1301 to move synchronously; during this process, the protruding column 1301 is in contact with the sliding block 701, and after the contact, the sliding block 701 is driven to slide in the sliding groove 601 towards the rotating block 5, thereby driving the partition plate 7 to move synchronously and compressing the first spring 8; and when the cover die 2 and the bottom die 1 are completely attached, the sliding block 701 is located at one end of the sliding groove 601 close to the rotating block 5. At this time, the elastic force of the first spring 8 can make the matching sleeve 13 have a tendency to slide outward in the positioning sleeve 4; and through the contact of the second locking block 503 and the locking groove 1401, this tendency can be offset, thereby improving the stability of the connection between the bottom die 1 and the cover die 2.

[0048] When the mold closing member releases the state of restricting the cover mold 2, the first spring 8 releases the elastic force, so that the sliding block 701 is driven to slide in the sliding groove 601 away from the rotating block 5 through the partition plate 7, and the cover mold 2 is driven to move synchronously through the extrusion of the convex column 1301 by the sliding block 701, so that the cover mold 2 is separated from the bottom mold 1, thereby completing the demolding action; the difficulty of demolding can be effectively reduced, and during the demolding process, no external force needs to be additionally applied to the bottom mold 1 and the cover mold 2, thereby effectively reducing the demolding cost (time cost, labor cost, etc.).

[0049] In another embodiment of the present application, the demolding member further comprises a fitting groove 602 opened on the fixed sleeve 6; the telescopic column 10 is provided with a giving slot 1001; the giving slot 1001 is slidably fitted with a wedge block 11; the giving slot 1001 is provided with a third spring 12; the two ends of the third spring 12 are respectively in contact with the telescopic column 10 and the wedge block 11; and the wedge block 11 cooperates with the fitting groove 602.

[0050] In another embodiment of the present application, the demolding member further comprises a second spring 9 arranged in the fixed sleeve 6, the two ends of the second spring 9 are respectively in contact with the telescopic column 10 and the partition plate 7; the wedge block 11 cooperates with the convex column 1301; and the telescopic column 10 cooperates with the fitting sleeve 13.

[0051] In use, for example, in the embodiment combining all the features described in the present application, during the mold closing process, the fitting sleeve 13 slides inwardly in the positioning sleeve 4, during which the cover mold 2 will be in contact with the telescopic column 10, and after the contact, the telescopic column 10 will slide inwardly in the fixed sleeve 6.

[0052] In the initial state, the wedge block 11 is immersed in the giving slot 1001, and the third spring 12 is in a compressed state; through the elastic force of the third spring 12, the wedge block 11 can be in contact with the inner wall of the fixed sleeve 6. The two sides of the end of the wedge block 11 are both provided with inclined surfaces (named as “upper inclined surface” and “lower inclined surface”); and the second spring 9 has an initial compression amount.

[0053] During the sliding process of the telescopic column 10, the wedge block 11 will slide synchronously to gradually approach the fitting groove 602; and when the cover mold 2 is completely attached to the bottom mold 1, the wedge block 11 is aligned with the fitting groove 602, at this time, under the elastic force of the third spring 12, the wedge block 11 will slide outwardly in the giving slot 1001 to gradually enter the fitting groove 602; at this time, through the contact of the fitting groove 602 and the wedge block 11 (the groove wall of the fitting groove 602 is in contact with the plane of the distal end of the wedge block 11), the telescopic column 10 can be limited to slide in the fixed sleeve 6.

[0054] And during the inward sliding of the telescopic column 10 in the fixed sleeve 6, the compression amount of the second spring 9 increases, thereby further increasing the elastic force of the second spring 9; and the elastic force of the second spring 9 acts on the telescopic column 10, thereby making the telescopic column 10 have a tendency to slide inward in the fixed sleeve 6; and this tendency is offset by the abutting fit of the wedge block 11 and the embedded slot 602.

[0055] When the clamping assembly releases the limiting state of the cover mold 2, the elastic force of the second spring 9 drives the cover mold 2 to continue to move away from the bottom mold 1 through the telescopic column 10, which can effectively reduce the difficulty of demolding, and during the demolding process, no additional external force needs to be applied vertically to the bottom mold 1 and the cover mold 2, which can effectively reduce the demolding cost (time cost, labor cost, etc.).

[0056] In another embodiment of the present application, when the clamping assembly limits the fitting sleeve 13, the first spring 8 and the second spring 9 are both in a compressed state; the elastic force of the first spring 8 is greater than that of the second spring 9; and the wedge block 11 cooperates with the embedded slot 602.

[0057] For example, in the use of the embodiment combining all the features described in the present application, in the clamping state, the elastic force of the first spring 8 is greater than that of the second spring 9. Therefore, when the clamping assembly releases the limiting state of the cover mold 2, the first spring 8 releases the elastic force earlier than the second spring 9.

[0058] During the elastic force release process of the first spring 8, since the telescopic column 10 cannot displace, the elastic force of the first spring 8 acts on the partition plate 7, thereby driving the cover mold 2 to move away from the bottom mold 1 through the sliding block 701. During this process, the moving partition plate 7 further compresses the second spring 9, thereby increasing the compression amount of the second spring 9; that is, during the elastic force release process of the first spring 8, part of the elastic force of the first spring 8 is converted into the energy storage of the second spring 9, and at the moment of the elastic force release of the first spring 8, the elastic force of the second spring 9 reduces the instantaneous kinetic energy of the elastic force release of the first spring 8, thereby reducing the “instantaneous peeling force” of the concrete and the inner wall of the mold, and avoiding the cracking or corner damage of the prefabricated part caused by stress concentration.

[0059] And during the elastic force release process of the first spring 8, the protruding column 1301 moves synchronously with the cover mold 2; after moving a distance, the protruding column 1301 abuts against and presses the lower inclined surface of the wedge block 11, thereby driving the wedge block 11 to slide inward in the accommodation slot 1001 and compress the third spring 12; thereby making the plane of the wedge block 11 separate from the slot wall of the embedded slot 602 (the upper inclined surface contacts the slot wall of the embedded slot 602, and the upper inclined surface can reduce the sliding resistance of the wedge block 11), at this time, under the action of the elastic force of the second spring 9, the telescopic column 10 slides outward in the fixed sleeve 6, thereby driving the cover mold 2 to further move away from the bottom mold 1, to facilitate subsequent removal of the drainage ditch prefabricated part.

[0060] When the cover mold 2 and the bottom mold 1 are completed, the cover mold 2 is limited by the closing member, the connection strength of the cover mold 2 and the bottom mold 1 can be ensured, and the smooth production of the drainage ditch concrete prefabricated part can be ensured; in the demolding process, the demolding member drives the cover mold 2 away from the bottom mold 1 through the partition plate 7 and the telescopic column 10 after the closing member is released from the limiting state, which can effectively reduce the difficulty of demolding, and in the demolding process, no external force perpendicular to the bottom mold 1 and the cover mold 2 needs to be applied, which can effectively reduce the demolding cost (time cost, labor cost, etc.).

[0061] In another embodiment of the application, a plurality of cross beams 201 are fixedly installed on the cover mold 2; the cross beams 201 are arranged along the width direction of the cover mold 2.

[0062] In use, the cross beams 201 can reduce the probability of stress deformation of the cover mold 2, thereby improving the finished product quality of the drainage ditch prefabricated part.

[0063] In another embodiment of the application, a protruding block is fixedly installed on the rotating block 5, and the protruding block is hexagonal.

[0064] In use, the hexagonal protruding block can improve the efficiency of the tool driving the rotating block 5 to rotate, thereby improving the efficiency of closing and demolding.

[0065] In another embodiment of the application, the inner wall of the bottom mold 1 and the surface of the outer wall of the cover mold 2 both have a smooth feature.

[0066] In use, the inner wall of the bottom mold 1 and the outer wall of the cover mold 2 with the smooth feature can reduce the probability of adhesion of concrete and the mold, thereby improving the finished product quality.

[0067] It is apparent for those skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered exemplary and non-limiting, and the scope of the application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced by the application.
