Description

Technical Field

[0001] This utility model relates to the field of water ditch mold technology, specifically a thin-walled prefabricated hydraulic channel mold. Background Technology

[0002] Precast ditch molds are forming tools used to produce ditches. The use of precast ditch molds facilitates the forming operation of precast ditches. However, when using existing precast ditch molds, the traditional mold side molds and end molds use a push-pull opening and closing mechanism. The advantage is that the mold can be demolded quickly, but the mold closing operation is troublesome. Precise alignment is required to screw the mold in, often using pry bars and other methods. Moreover, the top is equipped with a pull-out positioning pin and adjustable diagonal brace, making the mold closing process relatively complicated. In addition, due to the push-pull opening and closing mechanism, it occupies a large space, which is not conducive to production organization. Utility Model Content

[0003] The purpose of this utility model is to provide a thin-walled precast hydraulic channel mold to solve the problems mentioned in the background art, such as the troublesome mold closing operation and the large space occupation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a thin-walled precast hydraulic channel mold, comprising a base, an end mold and a side mold movably connected to the surface of the base via a rotating hinge, a supporting column fixedly connected to the surface of the base, an inner mold fixedly connected to the upper surface of the base, a demolding bolt provided on the surface of the inner mold, pin holes provided on both sides of the side mold, a tie rod penetrating through the middle of the side mold, and grooves provided on the bottom surfaces of the end mold and the side mold, with elastic rubber sealing strips embedded inside the grooves.

[0005] Preferably, the end mold and the side mold abut against each other, and the inner mold acts between the end mold and the side mold through the base, and the end mold, the side mold and the inner mold form a water channel space.

[0006] Preferably, the end mold and the side mold form a 35° angle with the base through the supporting columns.

[0007] Preferably, the supporting columns are distributed on both sides of the side mold and the end mold via bases, and the two ends of the tie rods penetrate the surface of the side mold.

[0008] Preferably, a positioning pin is connected through the surface of the end mold, and the positioning pin passes through the end mold and is connected to the pin hole. A slot is opened at the position where the side mold and the tie rod are connected, and the tie rod is inserted into the side mold through the slot.

[0009] Preferably, the base can be fixed on the assembly line to achieve standardized assembly line operation.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. A hinged mold design is adopted, with rotating hinges at the bottom of the side and end molds. The side and end molds are demolded and closed through the rotating hinges. To ensure safety, support columns are set at the bottom to prevent the side and end molds from tipping over. The design has a small footprint, and the mold is simple and convenient to operate. The mold can be fixed on the assembly line to achieve standardized assembly line operation and improve production efficiency. A groove is reserved on the side of the mold, and an elastic rubber sealing strip is embedded in the groove. When the mold is closed, the external force generated by the bolts and the tie positioning pins compresses the rubber strip to a tight seal, thereby achieving a slurry-stopping effect and improving the appearance and pass rate of the produced products.

[0018] Please see Figure 1-5 One embodiment provided by this utility model:

[0019] A thin-walled precast hydraulic channel mold includes a base 1. An end mold 2 and a side mold 3 are movably connected to the surface of the base 1 via a hinge. A support column 4 is fixedly connected to the surface of the base 1. An inner mold 5 is fixedly connected to the upper surface of the base 1. Demolding bolts 6 are provided on the surface of the inner mold 5. Pin holes 8 are provided on both sides of the side mold 3. A tie rod 7 is connected through the middle of the side mold 3. Grooves are formed on the bottom surfaces of the end mold 2 and the side mold 3, and elastic rubber sealing strips are embedded inside the grooves. The hinged connection between the base 1 and the end mold 2 facilitates the closing operation of the end mold 2 and the side mold 3. The support column 4 prevents the end mold 2 and the side mold 3 from directly tipping over, thus avoiding potential production safety hazards. Under the action of the elastic rubber sealing strip, when the end mold 2 and the side mold 3 are closed, the tie rod 7 and the positioning pin on the end mold 2 compress the elastic rubber sealing strip, achieving its anti-grouting effect.

[0020] Furthermore, the end mold 2 and the side mold 3 abut against each other, and the inner mold 5 acts between the end mold 2 and the side mold 3 through the base 1. The end mold 2, the side mold 3 and the inner mold 5 form a water ditch space. Through the abutting contact between the end mold 2 and the side mold 3, and with the use of the inner mold 5, the production operation of the water ditch is completed.

[0021] Furthermore, the end mold 2 and the side mold 3 form a 35° angle with the base 1 through the support column 4. Through the abutting contact between the end mold 2 and the side mold 3 and the support column 4, the end mold 2 and the side mold 3 are prevented from tilting directly and affecting the mold closing operation. With the support of the support column 4, the end mold 2 and the side mold 3 can be easily closed without affecting the demolding.

[0022] Furthermore, the support columns 4 are distributed on both sides of the side mold 3 and the end mold 2 via the base 1, and the two ends of the tie rod 7 penetrate the surface of the side mold 3. Through the action of the support columns 4, the end mold 2 and the side mold 3 are easily supported when they are opened. Under the action of the tie rod 7, the mold closing stability and support strength between the side molds 3 are improved.

[0023] Furthermore, a positioning pin is connected through the surface of the end mold 2, and the positioning pin connects the end mold 2 and the pin hole 8. A slot is opened at the position where the side mold 3 and the tie rod 7 are connected. The tie rod 7 is inserted into the side mold 3 through the slot. The connection between the positioning pin and the pin hole 8 on the end mold 2 improves the stability of the contact between the end mold 2 and the side mold 3. The slot on the side mold 3 facilitates the connection between the tie rod 7 and the side mold 3. When the side mold 3 is opened, the tie rod 7 can be separated from the side mold 3 to avoid the tie rod 7 affecting the normal rotation operation of the side mold 3.

[0024] Furthermore, the base 1 can be fixed on the assembly line to achieve standardized assembly line operation.

[0025] Working principle: During the molding operation of the water ditch, the end mold 2 and the side mold 3 are closed. At this time, the positioning pin and the pin hole 8 through the end mold 2 are connected, and the tie rod 7 is inserted into the side mold 3. The action of the positioning pin on the tie rod 7 and the end mold 2 causes them to squeeze the elastic rubber sealing strip to achieve the effect of stopping the slurry. After the injection molding is completed, the positioning pin and the tie rod 7 are released, and the end mold 2 and the side mold 3 are opened. Under the action of the support column 4, the end mold 2 and the side mold 3 can be supported, which facilitates the demolding of the molded water ditch. The base 1 can be connected to the production line to improve the production efficiency and standardized operation of the water ditch.
