Abstract
Description
Technical Field
[0001] This invention belongs to the field of PC component production technology, specifically relating to a dry and wet heat curing heating mold for PC components. Background Technology
[0002] PC components are precast concrete parts widely used in the field of residential industrialization. In their production process, curing is a crucial step, accounting for 70-80% of the entire production cycle. How to reduce energy consumption and improve curing efficiency is a major research direction.
[0003] Curing methods for PC components include moist heat curing and dry heat curing. Moist heat curing mainly uses steam curing kilns and shallow pit concrete platforms for curing. It uses saturated steam to heat the concrete, giving it a higher temperature and humidity to accelerate cementation and thus accelerate the hardening of the concrete. Dry curing is a curing method that does not use water vapor as a heat transfer medium. The PC components do not come into direct contact with the heat medium. A mold is installed on the concrete base frame, and a neat heating mold is inserted into the base frame to indirectly heat the concrete. Application number CN2019113807740 discloses a high-efficiency mold for PC components that integrates dry and wet heat curing. By setting up a curing chamber with embedded electric heating wires and a fan, steam is introduced into one end of the ventilation pipe to perform wet heat curing on the PC components in the curing chamber. Dry curing of the PC components in the curing chamber is achieved through the heating block and the sub-machine at the lower end of the cover. Although the heat in the curing chamber is not easy to dissipate, the number of PC components that can be cured at the same time is relatively small, which will affect the curing efficiency and continuity of the production line. Summary of the Invention
[0004] The purpose of this invention is to address the problem of low curing efficiency of existing curing molds by providing a dry and wet heat curing heating mold for PC components.
[0005] This invention is achieved through the following technical solution: a heating mold for dry and wet curing of PC components, comprising a mold for fixing PC components, a frame fixed on the ground, a rectangular curing cover provided inside the frame, the lower end of the rectangular curing cover being below the ground surface, the interior of the rectangular curing cover being a hollow cavity, including a first curing cavity, a second curing cavity, a third curing cavity, and a fourth curing cavity, the fourth curing cavity being located above the first curing cavity, the third curing cavity being located above the second curing cavity, and the first and second curing cavities, the third curing cavity, and the fourth curing cavity being separated by telescopic curtains respectively; the mold passes through the first curing cavity, the second curing cavity, the third curing cavity, and the fourth curing cavity in sequence, the side walls of the first and second curing cavities being provided with steam pipes, and the side walls of the third and fourth curing cavities being provided with ventilation pipes.
[0006] Specifically, a first support plate is provided at the bottom of the first maintenance chamber, and four first vertical cylinders are provided at the bottom of the first support plate. The first vertical cylinders are connected to the first support frame through the first vertical telescopic rod. A first horizontal cylinder is provided on one side of the upper surface of the first support plate, and the first horizontal cylinder is connected to the first push plate through the first horizontal telescopic rod.
[0007] A lifting support is provided on the right side of the second curing chamber. The lifting support includes a support base plate, a U-shaped outer baffle and two symmetrically arranged vertical rods on the support base plate. The top of the vertical rods is connected to the U-shaped upper baffle. A second vertical cylinder is provided below the support base plate. The second vertical cylinder is connected to the U-shaped bracket through a second vertical telescopic rod. The U-shaped bracket has an upward opening. Horizontal support rods are connected to the left side of the U-shaped bracket. The second vertical telescopic rod passes through the support base plate.
[0008] The front and rear sides of the third curing chamber are provided with symmetrically arranged L-shaped supports. The right side of the L-shaped support is provided with a second horizontal cylinder, which is connected to a second push plate through a second horizontal telescopic rod. The rectangular curing cover is provided with a fixing plate corresponding to the L-shaped support. The fixing plate is connected to the outside of the third horizontal cylinder, which is connected to the L-shaped support through a third horizontal telescopic rod.
[0009] The bottom of the fourth curing chamber is provided with a second support plate, and the top of the fourth curing chamber is provided with four third vertical cylinders. The third vertical cylinders are connected to the second support frame through third vertical telescopic rods.
[0010] Specifically, the rectangular curing cover has a through-inlet and a through-outlet on the left side. The through-outlet is located above the through-inlet. A functional cavity shell is provided between the through-inlet and the through-outlet. The functional cavity shell is provided with a retractable upper baffle and a retractable lower baffle. The retractable upper baffle extends upward to cover and fit the through-outlet, and the retractable lower baffle extends downward to cover and fit the through-inlet, which is used to cover the through-inlet and the through-outlet during the curing process.
[0011] A conveying mechanism is provided on the left side of the rectangular curing cover, and an inlet mechanism of the same height is provided outside the through entrance. The inlet mechanism includes a conveying component in the right direction, which works in conjunction with a pushing block in the right direction. The pushing block can push the mold table of the fixed PC component as a whole onto the surface of the first support frame. After multiple mold tables of fixed PC components are pushed in, they are stacked (there is a gap between the mold tables of adjacent fixed PC components, and they can be stacked stably). An outlet mechanism of the same height is provided outside the through exit. The outlet mechanism includes a conveying component in the left direction, which works in conjunction with a pulling mechanism in the left direction. The pulling mechanism can pull the mold table of the fixed PC component as a whole out onto the surface of the conveying component.

Furthermore, each curing chamber can correspond to multiple mounting holes, which can be adjusted according to the curing conditions.
[0016] Specifically, the distance between the outermost ends of the two transverse support rods is less than the width of the mold table; when the U-shaped bracket is at the top, the upper surface of the transverse support rod is at the same height as the horizontal plane of the L-shaped support. After the mold table of a set of fixed PC components is cured in the second curing chamber, it is transported as a whole to the third curing chamber and supported by the L-shaped support. After the transverse support rod is transported, it moves downward.
[0017] Specifically, the first support plate and the second support plate are fixed to the rectangular curing cover from the side. The first support plate mainly serves to separate the first curing chamber and the fourth curing chamber, while the second support plate limits and supports the second support frame.
[0018] The working process of a heating mold for dry and wet curing of PC components includes the following steps:
[0019] S1. Multiple fixed PC components are sequentially introduced into the mold table from the through entrance. The first vertical cylinder drives the first support frame to descend step by step. After being filled, the first mold table group is obtained.
[0020] S2. Close the retractable lower baffle, open the steam pipe at the first curing chamber, and introduce steam for curing for a certain period of time.
[0021] S3. Using the cooperation of the first horizontal cylinder and the first push plate, the first mold assembly is pushed to the right and placed on the horizontal support rod. After completion, the first support frame rises, and at the same time, S1 is executed to gradually introduce the second mold assembly.
[0022] S4. After importing, execute S2 and simultaneously open the steam pipe from the second curing chamber to introduce steam for curing.
[0023] S5. Drive the horizontal support rod upward by the second vertical cylinder to push the second mold assembly between the L-shaped supports. Drive the L-shaped supports inward by the third horizontal cylinder to clamp the second mold assembly from the front and rear sides.
[0024] S6. The second vertical cylinder drives the horizontal support rod to move downward until it reaches the bottom. Then, S3 and S4 are executed in sequence. At the same time, the ventilation pipe of the third curing chamber is opened to introduce high-temperature gas for curing.
[0025] S7. Drive the second push plate through the second horizontal cylinder to push the first mold assembly to the left onto the second support frame. After completion, drive the L-shaped support to move outward through the third horizontal cylinder. Execute S5 and S6 in sequence. At the same time, open the ventilation pipe of the fourth curing chamber and introduce high-temperature gas for curing.
[0026] S8, the third vertical cylinder drives the second support frame to rise step by step, and the mold table with fixed PC components is exported one by one by the export mechanism.
[0027] The telescopic curtain retracts when the transfer mold assembly is used, and opens at other times to separate the first, second, third, and fourth curing chambers; the rectangular curing cover is assembled and supported by color steel plates, and the inner wall of the color steel plates is provided with insulation board and extruded polystyrene insulation board.
[0028] Compared with the prior art, the present invention has the following advantages: it effectively utilizes above-ground and underground space to form four curing chambers in three-dimensional space, and rationally sets through entrances and through exits on the rectangular curing cover to reduce heat loss; the mold assembly is discharged after passing through steam curing and hot gas curing in sequence, and multiple mold assemblies are cured at the same time.
