Description

Technical Field

[0001] This utility model relates to the field of pipe pile production technology, specifically a pipe pile production mold. Background Technology

[0002] Pipe pile production molds are tools used to produce precast concrete pipe piles. They can be divided into several types, such as casting molds, adjustable molds, and accessory molds. They can be used to produce concrete piles with warning and positioning functions and are widely used in underground facility marking projects such as municipal, communication, and gas facilities.

[0003] In existing technologies, after injecting raw materials into the pipe pile production mold, it is necessary to connect and fix the upper mold and the lower mold in the pipe pile production mold. However, the upper mold and the lower mold are mostly fixed with bolts. When fixing the upper mold and the lower mold, it is also necessary to use external tools to tighten multiple bolts, which is cumbersome and time-consuming, affecting production efficiency. Moreover, the inner walls of the upper mold and the lower mold are prone to wear after long-term use. After wear, it will affect the quality of subsequent pipe pile production. In order not to affect the production operation of pipe piles, all of them need to be replaced after wear, resulting in waste of resources. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] A type of pipe pile production mold, such as Figures 1-8 As shown, the upper mold 1 and the lower mold 2 are included. Connecting plates 1 and 20 are fixedly connected to the outer walls of the upper mold 1 near both ends. Connecting plates 21 are fixedly connected to the outer walls of the lower mold 2 near both sides. A connecting mechanism is provided between the outer walls of connecting plates 1 and 21. An inner mold 19 is provided inside both the upper mold 1 and the lower mold 2. The connecting mechanism includes a clamping plate 1 6, a wedge block 10 and a limiting block 8. The clamping plate 1 6 is rotatably connected to the outer wall of the connecting plate 21 via a shaft. One end of the clamping plate 1 6 is rotatably connected to the clamping plate 2 7 via a shaft. The wedge block 10 is inserted into the outer wall of the connecting plate 1 20. The limiting block 8 is inserted into the upper surface of the connecting plate 1 20, and the bottom end of the limiting block 8 is slidably connected to the wedge block 10.

[0030] A connecting plate 11 is fixedly connected to one end of the wedge block 10. A telescopic push rod 9 is installed between the outer wall of the connecting plate 11 and the inner wall of the connecting plate 20. A return spring is sleeved on the outside of the telescopic push rod 9. A fixing groove is opened through the upper surface of the clamping plate 7, and the fixing groove fits with the limiting block 8. The two outer side walls of the limiting block 8 are provided with clamping grooves 15. The limiting block 8 is slidably connected to the wedge block 10 but does not separate from the wedge block 10. The rebound force of the telescopic push rod 9 can drive the connecting plate 11 to reset, thereby pushing the wedge block 10 and the limiting block 8 to reset.

[0031] A sliding rod 14 is fixedly installed on the upper surface of the second card plate 7 near both sides of the limiting block 8. A locking block 12 and a limiting spring are sleeved on the outside of the sliding rod 14. One end of the locking block 12 fits into the locking groove 15. A fixing rod 13 is inserted into the upper surface of the locking block 12. A fixing hole is opened on the outer wall of the sliding rod 14, and the fixing hole fits into the fixing rod 13. By passing the fixing rod 13 through the locking block 12 and inserting it into the fixing hole, the position between the locking block 12 and the sliding rod 14 can be fixed. The limiting spring, together with the sliding rod 14, plays a supporting and limiting role in the position of the locking block 12.

[0032] After the raw material is injected between the upper mold 1 and the lower mold 2 and the mold is closed, the clamping plate 6 in the connecting mechanism is rotated so that the inner wall of the clamping plate 6 is in close contact with the outer wall of the connecting plate 21 and is in a vertical position. The wedge block 10 is pressed and moved into the connecting plate 20, which drives the connecting plate 11 and the wedge block 10 to move into the connecting plate 20. The telescopic push rod 9 retracts, thereby driving the limiting block 8 to move upward. Then the clamping plate 7 is rotated so that the clamping plate 7 is sleeved on the outside of the limiting block 8 through the fixing groove. Then the clamping block moves along the outside of the slide rod 14. 12. Insert one end of the locking block 12 into the locking groove 15, and insert the fixing rod 13 through the locking block 12 into the fixing hole to fix the position between the limiting block 8 and the second locking plate 7. This will fix the second locking plate 7 well on the second connecting plate 21, thereby fixing the position between the first connecting plate 20 and the second connecting plate 21. This will make the upper mold 1 and the lower mold 2 well connected and fixed. Through the above operation, the upper mold 1 and the lower mold 2 can be fixed without the aid of tools, which can effectively improve the working efficiency of producing pipe piles.

[0033] Arc-shaped frames 4 are fixedly connected to both ends of the outer wall of the inner mold 19. Arc-shaped limiting plates 5 are inserted inside the arc-shaped frames 4, and one end of the arc-shaped limiting plates 5 is fixedly connected to the upper mold 1. Several bolts 16 are fixedly connected to the outer wall of the arc-shaped limiting plates 5. Each bolt 16 is threaded with a stop block 17. The inner wall of the stop block 17 and the bolt 16 is provided with a thread that matches the bolt 16. With the cooperation of the threads, the stop block 17 can be tightly locked with the bolt 16 to limit and fix the position between the arc-shaped limiting plates 5 and the arc-shaped frames 4.

[0034] Specifically, by setting an inner mold 19 to shield and protect the inner walls of the upper mold 1 and the lower mold 2, when the inner mold 19 is worn, simply rotate the stop 17 along the outside of the bolt 16 to release the stop 17 from blocking one side of the arc frame 4, thereby releasing the fixation between the inner mold 19 and the upper mold 1. At this time, the inner mold 19 can be moved out of the upper mold 1 for replacement. Similarly, the inner mold 19 in the lower mold 2 can be replaced, so that when wear occurs, it is not necessary to replace the entire upper mold 1 and the lower mold 2, effectively saving resources.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
