Description

Technical Field

[0001] This utility model relates to the field of cold storage panel production technology, and in particular to a temperature control structure for a mold used for foaming and curing multi-layer cold storage panels. Background Technology

[0002] Cold storage panels are typically made of an outer metal protective panel and an inner foam core material. The curing quality of the foam core material is the key factor determining the overall performance of multi-layer cold storage panels. Under suitable temperature conditions, the foam material completes a full chemical reaction, forming a uniform and dense cell structure, thereby achieving thermal insulation. Currently, the heating methods for molds used in the curing of cold storage panels are mainly divided into two categories: traditional heating and semi-automatic heating.

[0003] Currently, traditional heating methods often employ electric heating elements directly embedded within the mold. The heat generated by the electric heating element is conducted to the mold cavity surface, providing the necessary temperature for the foamed material to cure. While this method offers lower equipment costs and easier initial installation, it suffers from significant uneven temperature distribution. Because the heating zone of the electric heating element is concentrated around the tube, the temperature varies across different areas of the mold cavity, leading to inconsistent curing rates of the foamed core material within the cold storage panel. Core material near higher temperatures is prone to over-crosslinking and increased brittleness, while lower-temperature areas may experience insufficient curing and lower density, affecting the long-term insulation performance and structural durability of the cold storage panel. Therefore, a temperature control structure for the mold used in the curing of multi-layer cold storage panel foam is needed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a temperature control structure for a mold used in the foaming and curing of multi-layer cold storage panels. This solves the problem that traditional processes use electric heating tubes embedded in the mold for heating, which, although low in cost and easy to install, result in uneven temperature, leading to inconsistent curing of the core material and affecting the insulation and durability of the cold storage panels.

[0006] This utility model embodiment adopts the following technical solution: a temperature control structure for a mold used in the foaming and curing of multi-layer cold storage panels. It mainly includes a mold assembly comprising four sets of frame plates, which together form a frame structure. Within the frame structure, partition plates are equidistantly spaced, creating cooling spaces that achieve temperature control. Multiple sets of horizontally and vertically arranged pipes are installed within these cooling spaces, with gaps between them. Sealing covers are fixed to the bottom and top surfaces of the frame structure. A temperature control component is also included, located on the side of one set of frame plates. This component includes a water inlet for adjusting the water flow rate, and a drain section on the side of the frame plate opposite the water inlet. Mounting brackets are fixed to the sides of two opposing sets of frame plates. The mold assembly and the temperature control component together form a temperature control device, adaptable to multi-layer installation requirements with vertical spacing.

[0007] Furthermore, the sealing cover plate located on the top surface supports the cold storage panel, directly contacts the cold storage panel, bears the weight of the cold storage panel, and forms a temperature control structure with the help of the frame and pipelines below.

[0008] Furthermore, the water inlet includes multiple sets of water collection tanks fixed to the side of a set of frame plates. The number of water collection tanks corresponds to the number of cooling spaces. One end of each set of pipes in the corresponding cooling space passes through the frame plate and is connected to the water collection tank. A water regulating valve is connected to the side of each water collection tank via a pipe. The inlets of the multiple sets of water regulating valves are connected to water inlet pipes. The water inlet pipes have inlet ends, one end of which is adapted to be connected to an external water supply device.

[0009] Furthermore, the drainage section includes multiple sets of water collection tanks II disposed on the side of the frame plate. The number of water collection tanks II corresponds to the number of cooling spaces. The other end of the multiple sets of pipes in the corresponding cooling spaces passes through the frame plate from the cooling space and connects to the water collection tanks II.

[0010] Furthermore, multiple sets of the water collection tanks are connected to drain pipes via flanges. The drain pipes have an L-shaped structure, and the drain end of the drain pipe is close to the water inlet end.

[0011] Furthermore, multiple cooling spaces are provided with clamping parts perpendicular to and connected to the partition plates. The clamping parts include horizontal bars fixed vertically to the partition plates. Multiple sets of pipe clamps are provided on the horizontal bars to match the pipe spacing. Each pipe clamp consists of two sets of opposing clamping plates. The two sets of opposing clamping plates have multiple sets of opposing semi-circular arc-shaped portions extending outward. The two sets of opposing arc-shaped portions are suitable for holding the pipes.

[0012] Furthermore, the frame structure is covered by a U-shaped cover, which is used for the installation of the water inlet and drainage parts. The cover is fixed to the sealing cover plate to provide protection.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A temperature control structure for a mold used in the foaming and curing of multi-layer cold storage panels is disclosed. The mold assembly divides the cooling space using partition plates, and multiple sets of horizontally and vertically arranged pipes with gaps are combined with the flow regulation function of the water inlet of the temperature control component. This allows for temperature control of each cooling space, ensuring even heat transfer to the cold storage panels on the sealed cover and guaranteeing uniform curing of the core material. Simultaneously, the mounting brackets on the side of the frame facilitate overall fixation, and the temperature control device, composed of the mold assembly and the temperature control component, supports vertically spaced installation, adapting to the synchronous temperature control requirements of multi-layer cold storage panels. This balances production efficiency and product quality stability, effectively solving the problem of uneven temperature distribution in traditional methods where electric heating tubes are directly embedded in the mold, thus improving the foaming and curing quality and production adaptability of multi-layer cold storage panels.

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] Reference Figures 1-3 As shown in the figure, the present invention provides a temperature control structure for a mold used for foaming and curing of multi-layer cold storage panels, including a mold assembly 1. The mold assembly 1 includes four sets of frame plates 11, which together form a frame structure. The frame structure is provided with partition plates 12 at equal intervals. The partition plates 12 divide the frame structure to form a cooling space that achieves the temperature control function. In addition, multiple sets of horizontally and vertically arranged pipes 13 are provided in the multiple cooling spaces. There are gaps between the multiple sets of pipes 13, and the two ends of the pipes 13 penetrate the frame plates 11 on both sides.

[0025] Meanwhile, a clamping part is provided in multiple cooling spaces, perpendicular to the partition plate 12 and connected to the partition plate 12. The clamping part is used to support multiple vertically arranged pipes 13, so that the pipes 13 maintain a predetermined position in the cooling space. The clamping part includes a horizontal bar 14 vertically fixed on the partition plate 12. Multiple pipe clamps 15 are provided on the horizontal bar 14 to match the spacing of the pipes 13. Each pipe clamp 15 is composed of two sets of opposing clamping plates. The two sets of opposing clamping plates have multiple sets of opposing semi-circular arc-shaped parts that extend outward. The two sets of opposing arc-shaped parts are suitable for holding the pipes 13 to play a fixed support role.

[0026] Furthermore, sealing cover plates 16 are fixed to the bottom and top surfaces of the frame structure with fasteners to seal the bottom and top surfaces of the frame structure, creating a relatively sealed environment for the internal cooling space. This helps the temperature control medium to circulate stably in and around the pipes 13. It should be noted that the sealing cover plate 16 on the top surface is used to support the cold storage panel, directly contacting the cold storage panel and bearing its weight. At the same time, it forms a temperature control structure with the help of the frame and pipes 13 below, providing a stable temperature environment for the foaming and curing process of the cold storage panel.

[0027] A temperature control component 2 is provided on the side of a set of frame plates 11. The temperature control component 2 is used to supply hot water to the pipes 13 in multiple cooling spaces to provide power and temperature regulation support. The temperature control component 2 includes a water inlet on the side of a set of frame plates 11. The water inlet includes multiple water collection tanks 21 fixed on the side of a set of frame plates 11. The number of water collection tanks 21 corresponds to the number of cooling spaces. One end of the multiple pipes 13 in the corresponding cooling space passes through the frame plate 11 and is connected to the water collection tank 21. It can be understood that one end of the multiple pipes 13 in the corresponding cooling space passes through the frame plate 11 from the cooling space and extends to the side of the water collection tank 21 to achieve connection. Thus, the water collection tank 21 will distribute hot water to the pipes 13 in the corresponding cooling space.

[0028] A water regulating valve 22 is connected to the side of the water collection tank 21 via a pipe. The water regulating valve 22 is used to regulate the amount of water entering the water collection tank 21, thereby regulating the temperature of a certain cooling space. Temperature control is achieved by adjusting the water flow rate. A water inlet pipe 23 is connected to the inlet of the multiple water regulating valves 22. The water inlet pipe 23 has an inlet end 231, and one end of the inlet end 231 is suitable for connection to an external water supply device to provide a hot water source for the entire water inlet section.

[0029] Meanwhile, a drainage section is provided on the side of the frame plate 11 opposite to the water inlet section. The drainage section includes multiple sets of water collection tanks 26 provided on the side of the frame plate 11. The number of water collection tanks 26 corresponds to the number of cooling spaces. The other end of the multiple sets of pipes 13 in the corresponding cooling spaces passes through the frame plate 11 from the cooling space and connects to the water collection tanks 26. After the hot water completes heat exchange in the pipes 13, it can be collected in the water collection tanks 26 in preparation for discharge.

[0030] Multiple sets of water collection tanks 26 are connected to drain pipes 28 via flange pipes 27. The drain pipes 28 have an L-shaped structure and the drain end 281 is close to the water inlet end 231 to facilitate subsequent connection with external water supply equipment, forming a more efficient pipeline 13 arrangement. A U-shaped cover 24 is fitted over the frame structure. The cover 24 is used for the installation of the water inlet and drain sections. The cover 24 is fixed to the sealing cover plate 16 to provide protection.

[0031] Furthermore, mounting brackets 25 are fixed to the sides of the two sets of frame plates 11 arranged opposite to each other by fasteners, forming an outwardly extending support structure, which is suitable for installing the mold assembly 1 in a designated position. It should also be noted that, in order to adapt to the temperature control of multi-layer cold storage panels, the temperature control device composed of the mold assembly 1 and the temperature control assembly 2 can be arranged vertically at intervals. In combination with the overall structural dimensions and the number of cold storage panel layers, multiple sets of temperature control devices can be stacked vertically at a set interval, with each layer of devices corresponding to the temperature control requirements of one set of cold storage panels.

[0032] Working principle: First, the external water supply equipment continuously supplies hot water into the inlet pipe 23 through the inlet end 231 of the inlet pipe 23. The hot water then flows into multiple sets of water regulating valves 22 connected to the inlet pipe 23. The water regulating valves 22 can flexibly adjust the flow rate of hot water entering the corresponding water collection tank 21 according to the actual temperature control requirements. After the hot water of different flow rates enters the water collection tank 21, it will be accurately distributed to multiple sets of pipes 13 connected to the water collection tank 21 and in the corresponding cooling space, so as to transfer the heat of the hot water to the surrounding space, avoiding the disadvantages of local high temperature and local low temperature of traditional electric heating tubes. The cold storage panel to be foamed and cured is placed on the sealing cover plate 16 on the top surface of the frame structure. The hot water flowing in the pipe 13 creates the required stable temperature environment for the cold storage panel through heat exchange, helping it to successfully complete the uniform foaming and curing process.

[0033] Next, the hot water that has completed heat exchange in pipe 13 will flow out from the other end of pipe 13, pass through frame plate 11 and flow into the water collection tank 26 of the corresponding cooling space, and then be transported to drain pipe 28 through flange pipe 27. Since drain pipe 28 is L-shaped and drain end 281 is close to water inlet end 231 of water inlet pipe 23, the water that has completed heat exchange can be easily guided to external recycling or reprocessing equipment, thus forming a complete hot water circulation temperature control process. At the same time, the sealing cover plate 16 on the bottom and top surfaces of the frame structure makes the internal cooling space form a relatively closed environment, allowing the temperature control medium (hot water) to circulate stably in and around pipe 13, further improving the temperature control effect.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
