Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a production mold for cement utility poles. Background Technology

[0002] Cement poles, commonly known as utility poles or concrete poles, are poles made of concrete and steel bars or wires. The cross-sectional shapes of the poles include square, octagonal, I-shaped, ring, or other irregular shapes. The most commonly used cross-sections are ring and square. The length of the poles is generally 4.5 to 15 meters. Ring poles come in two types: tapered and equal diameter.

[0003] Currently, existing cement utility poles are manufactured by pressing them together using molds. However, these molds have some shortcomings. Poor sealing and structural design when the two molds are closed can easily lead to defects such as uneven surfaces and internal voids in the utility poles, affecting the stable processing of the cement poles. Therefore, we propose a new cement utility pole production mold to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a cement pole production mold that can solve the technical problem that the existing two molds have poor sealing and structural design when they are closed, which easily leads to unevenness on the surface of the pole.

[0006] To solve the above-mentioned technical problems, this utility model provides a cement pole production mold, which adopts the following technical solution: it includes a base, a lower mold base is fixedly installed on the upper end of the base, an upper mold base is provided on the upper end of the lower mold base and adapted to the position of the lower mold base, both the upper mold base and the lower mold base are set in a semi-mold shape, sealing protrusions are fixedly installed on both sides of the bottom of the upper mold base, rubber sealing gaskets are fixedly installed on the top of the sealing protrusions, sealing rings are provided on both sides of the upper end of the lower mold base, L-shaped protrusions are fixedly installed on both sides of the outer wall of the upper mold base and the lower mold base, limit frames are slidably inserted into the outer walls of the two sets of L-shaped protrusions, and a locking structure is provided between the two ends of the upper mold base and the lower mold base.

[0007] Optionally, sealing grooves are provided on both sides of the upper end of the lower mold base, and the sealing ring is fixedly installed inside the sealing groove. The size of the sealing ring is adapted to the size of the sealing groove, and the sealing protrusion is pressed inside the sealing groove.

[0008] Optionally, both sets of L-shaped protrusions have slidably inserted limit frames on their outer walls. The limit frames have grooves inside, and the grooves are adapted to the size of the L-shaped protrusions.

[0009] Optionally, cooling pipes are fixedly installed at the inner mold of both the upper mold base and the lower mold base, and the cooling pipes are connected to the external liquid storage tank through pipes.

[0010] Optionally, lifting rings are symmetrically fixedly installed on the upper end of the upper mold base, a feed pipe is fixedly installed in the middle of the upper end of the upper mold base, and a vibrator is fixedly installed on the outer wall of the upper mold base.

[0011] Optionally, both ends of the outer wall of the upper mold base and the lower mold base are fixedly provided with demolding rings, and demolding cylinders are fixedly installed on both sides inside the demolding rings at both ends of the lower mold base. Demolding grooves are opened on both sides inside the demolding rings on the outer wall of the upper mold base, and one end of the demolding cylinder is adapted to the size of the demolding groove.

[0012] The locking structure includes mounting protrusions symmetrically fixedly mounted on both ends of the upper mold base. Positioning rods are fixedly mounted inside both sets of mounting protrusions. Movable plates are rotatably mounted on the outer walls of the positioning rods. U-shaped retaining tubes are rotatably mounted on the outer walls of the movable plates. One end of the U-shaped retaining tube is inserted into a limiting block. The limiting blocks are fixedly mounted on both ends of the lower mold base at positions corresponding to the mounting protrusions.

[0013] In summary, this utility model has at least one of the following beneficial effects: 1. By stably connecting and limiting the sealing protrusion at the bottom of the upper mold base with the sealing groove on the lower mold base, the rubber sealing gasket at the bottom of the sealing protrusion and the sealing ring in the sealing groove are stably squeezed and adhered, so that the upper mold base and the lower mold base are relatively sealed when they are connected. By using two limiting frames to limit the insertion of two sets of L-shaped protrusions on the outer walls of the upper mold base and the lower mold base, by moving the movable plate on the mounting protrusion, the movable plate drives the U-shaped clamping tube to move, so that one end of the U-shaped clamping tube is clamped on the limiting block. Then, pressing the movable plate facilitates the pre-tightening of the limiting block, thereby facilitating the connection and sealing of the upper mold base and the lower mold base while improving its tightness. The use of the sealing structure and vibrator effectively avoids problems such as uneven surface and internal voids of the utility pole, and improves the product qualification rate.

[0014] By setting up two sets of demolding cylinders and cooling pipes, the cement poles are cooled using the cooling pipes in the upper and lower mold bases to facilitate demolding. Then, the demolding cylinders in the demolding rings at both ends of the lower mold base are activated. The two sets of demolding cylinders simultaneously drive the demolding grooves in the demolding rings on the outside of the upper mold base to lift up, causing the upper mold base to separate quickly. This facilitates rapid cooling and demolding of the cement poles, improving the processing efficiency of the cement poles. Attached Figure Description

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1 —5. This utility model will be described in further detail.

[0020] Reference Figures 1-5 In this embodiment, in order to solve the technical problem that the existing two molds have poor sealing and structural design when they are closed, which easily leads to unevenness on the surface of the utility pole, this utility model discloses a cement utility pole production mold. The base 1 has a lower mold base 2 fixedly installed on its upper end. The upper end of the lower mold base 2 is provided with an upper mold base 3 that matches the position of the lower mold base 2. Both the upper mold base 3 and the lower mold base 2 are set in a semi-mold shape. Both sides of the bottom of the upper mold base 3 are fixedly installed with sealing protrusions 13. Both top of the sealing protrusions 13 are fixedly installed with rubber sealing gaskets 14. Both sides of the upper end of the lower mold base 2 are provided with sealing rings 12. Both sides of the outer wall of the upper mold base 3 and the lower mold base 2 are fixedly installed with L-shaped protrusions 82. Both sets of L-shaped protrusions 82 are slidably inserted into the outer wall of the two sets of L-shaped protrusions 82. A locking structure 9 is provided between the two ends of the upper mold base 3 and the lower mold base 2. Specifically, sealing grooves 11 are provided on both sides of the upper end of the lower mold base 2, and sealing rings 12 are fixedly installed inside the sealing grooves 11. The size of the sealing rings 12 and the sealing grooves 11 are matched, and the sealing protrusions 13 are pressed inside the sealing grooves 11.

[0021] When the upper mold base 3 and the lower mold base 2 are connected and locked together, the sealing protrusion 13 drives the rubber sealing gasket 14 to squeeze the sealing ring 12 in the sealing groove 11. The sealing ring 12 is made of high temperature resistant and aging resistant material, which facilitates filling the gap when the upper mold base 3 and the lower mold base 2 are connected, and improves the sealing performance of the connection between the upper mold base 3 and the lower mold base 2. Specifically, the outer walls of the two sets of L-shaped protrusions 82 are slidably connected to the limit frame 8, and the limit frame 8 has a groove 81 inside, which is adapted to the size of the L-shaped protrusion 82.

[0022] After the upper mold base 3 and the lower mold base 2 are connected, the two sets of L-shaped protrusions 82 are inserted and limited by the groove 81 in the limiting frame 8, which facilitates the tightening of the upper mold base 3 and the lower mold base 2 and prevents the position displacement from affecting the processing operation of the cement pole. The upper and lower molds are made of high-strength alloy steel and have undergone special treatment to enhance wear resistance and corrosion resistance. Specifically, cooling pipes 10 are fixedly installed at the inner mold of both the upper mold base 3 and the lower mold base 2, and the cooling pipes 10 are connected to the external liquid storage tank through pipes.

[0023] By setting cooling pipes 10 in the inner molds of the upper mold base 3 and the lower mold base 2, and connecting one end of the cooling pipes 10 to the outer liquid storage tank, and transporting liquid through the pump body, it is convenient to cool down the solidified cement pole and facilitate demolding. The existing technology is already mature. Specifically, a lifting ring 5 is symmetrically fixedly installed on the upper end of the upper mold base 3, a feed pipe 4 is fixedly installed in the middle of the upper end of the upper mold base 3, and a vibrator 6 is fixedly installed on the outer wall of the upper mold base 3.

[0024] The lifting ring 5 is set to facilitate the lifting of the upper mold base 3 and the docking with the lower mold base 2. At the same time, the vibrator 6 is set to eliminate air bubbles during the concrete pouring process, thereby improving product quality. Specifically, both ends of the outer wall of the upper mold base 3 and the lower mold base 2 are fixedly provided with demolding rings 7. Both sides of the inner side of the demolding rings 7 at both ends of the lower mold base 2 are fixedly installed with demolding cylinders 15. Both sides of the inner side of the demolding rings 7 on the outer wall of the upper mold base 3 are provided with demolding grooves 16. One end of the demolding cylinder 15 is adapted to the size of the demolding groove 16.

[0025] By setting a demolding cylinder 15 in the demolding ring 7 on the outer side of the lower mold base 2, it is easy to quickly separate the demolding ring 7 on the outer side of the upper mold base 3, which facilitates the demolding of cement utility poles.

[0026] Specifically, the locking structure 9 includes mounting protrusions 91 that are symmetrically fixedly installed on both ends of the upper mold base 3. Each of the two sets of mounting protrusions 91 has a positioning rod fixedly installed inside. A movable plate 92 is rotatably installed on the outer wall of the positioning rod. A U-shaped retaining tube 93 is rotatably installed on the outer wall of the movable plate 92. One end of the U-shaped retaining tube 93 is inserted into a limiting block 94. The limiting block 94 is fixedly installed on both ends of the lower mold base 2 at positions corresponding to the mounting protrusions 91.

[0027] When the upper mold base 3 and the lower mold base 2 are aligned and installed, the movable plate 92 on the mounting protrusion 91 is moved to move the U-shaped clamping pipe 93, so that one end of the U-shaped clamping pipe 93 is engaged with the limiting block 94. Then, the movable plate 92 is pressed to pre-tighten the limiting block 94, thereby effectively limiting the upper mold base 3 and the lower mold base 2 and improving the stability of the cement pole molding.

[0028] The specific working principle is as follows: When processing and injection molding cement utility poles, the operator aligns the hoist with the lifting ring 5 on the upper mold base 3, then lifts the upper mold base 3 above the lower mold base 2, and slowly lowers it. This stabilizes and limits the connection between the sealing protrusion 13 at the bottom of the upper mold base 3 and the sealing groove 11 on the lower mold base 2, causing the rubber sealing gasket 14 at the bottom of the sealing protrusion 13 to be stably pressed and adhered to the sealing ring 12 in the sealing groove 11. This ensures a relatively sealed connection between the upper mold base 3 and the lower mold base 2. After completion, two sets of L-shaped protrusions 82 on the outer walls of the upper mold base 3 and the lower mold base 2 are inserted and limited by two limiting brackets 8. Then, by moving the movable plate 92 on the mounting protrusion 91, the movable plate 92 drives the U-shaped clamping pipe 93 to move, so that one end of the U-shaped clamping pipe 93 is clamped on the limiting block 94. Then, the movable plate 92 is pressed to pre-tighten the limiting block 94, thereby facilitating the connection and sealing of the upper mold base 3 and the lower mold base 2 while improving its tightness, and effectively stabilizing the processing of cement power poles. After the upper mold base 3 and the lower mold base 2 are connected, the operator injects concrete into the feed pipe 4. After pouring to the preset amount, the vibrator 6 is driven to eliminate air bubbles in the concrete, which helps to improve the quality of the cement pole. After the cement solidifies, the cooling pipes 10 in the upper mold base 3 and the lower mold base 2 are used to cool the cement pole for easy demolding. At the same time, the limiting frame 8 is pulled out, and then the U-shaped clamping pipe 93 is displaced from the limiting block 94, thereby activating the demolding cylinders 15 in the demolding rings 7 at both ends of the lower mold base 2. The two sets of demolding cylinders 15 synchronously drive the demolding grooves 16 in the demolding rings 7 on the outside of the upper mold base 3 to lift up, causing the upper mold base 3 to separate quickly, making it easy to remove the cement pole.
