Description

Technical Field

[0001] This utility model belongs to the field of hydraulic molding machines, and specifically relates to a heat insulation structure for hydraulic molding machines. Background Technology

[0002] Existing hydraulic presses have certain technical shortcomings in terms of heat insulation, mainly manifested in inadequate heat transfer control, which can easily lead to an increase in the ambient temperature around the equipment, affecting operational safety and equipment stability. This shortcoming stems primarily from the fact that during operation, the hydraulic system generates a large amount of heat under high load, and the metal body has high thermal conductivity, making it easy for heat to be conducted from high-temperature areas to low-temperature areas. This problem of insufficient heat insulation performance is particularly prominent in high-temperature operating environments.

[0003] To address this issue, the conventional approach is to add heat insulation materials, such as ceramic fibers or aluminum silicate cotton, to the surface of the equipment to slow down heat conduction. However, this method has significant drawbacks, such as the heat insulation materials being prone to aging and detachment when exposed to high temperatures for extended periods, leading to a decrease in insulation effectiveness. Therefore, we aim to design a welding equipment with a novel structure to solve this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a heat insulation structure for a hydraulic molding machine to solve the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a heat insulation structure for a hydraulic molding machine, comprising: a base, a lower mold base for installing a lower molding die is installed on the upper side of the base, an upper mold base for installing an upper die is movably installed on the upper side of the lower mold base via four guide pillars and a top seat, a heat insulation cavity one for blocking heat transfer is respectively provided inside the left and right sides of the base, a heat insulation cavity two is provided inside the lower mold base for blocking the heat after the lower mold is heated from being transferred to the lower mold base, and a heat insulation cavity three is provided inside the upper mold base for blocking the heat after the upper mold is heated from being transferred to the lower mold base.

[0006] In a preferred embodiment, a heat dissipation hole 1 is formed through the left and right sides of the heat insulation cavity 1, and the two heat dissipation holes 1 are arranged in an axially symmetrical structure with their centers collinear. A heat dissipation hole 2 is formed through the top of the heat dissipation hole 1. In actual use, the setting of the heat insulation cavity 1 can reduce the heat accumulation after the base is heated and also reduce the speed of heat transfer from the upper side.

[0007] In a preferred embodiment, the heat insulation cavity 2 is provided with multiple reinforcing plates in a star-shaped structure to enhance the pressure resistance of the lower mold base. Each of the multiple reinforcing plates has a through hole in the middle. The top inner wall of the heat insulation cavity 2 is provided with a heat insulation plate. The heat insulation cavity 2 can prevent a large amount of heat from being transferred to the lower mold base and can form a certain blocking effect.

[0008] In a preferred embodiment, the bottom of the heat insulation cavity 2 is provided with a connecting hole for the heat dissipation hole 2 to connect, and a heat dissipation hole 3 is provided on the left and right sides of the heat insulation cavity 2 to reduce the heat accumulation inside the heat insulation cavity 2.

[0009] In a preferred embodiment, the heat insulation cavity 3 is provided with multiple reinforcing plates 2 in a cross-shaped structure to enhance the pressure resistance of the upper mold base. Each of the multiple reinforcing plates 2 has a through hole 2 formed in the middle. The bottom inner wall of the heat insulation cavity 3 is provided with a heat insulation plate 2. In actual use, the heat insulation cavity 3 can prevent a large amount of heat from being transferred to the upper mold base and can form a certain blocking effect.

[0010] In a preferred embodiment, the top of the heat insulation cavity three is provided with a plurality of heat dissipation holes four arranged in a circular structure, and the left and right sides of the heat insulation cavity three are respectively provided with a heat dissipation hole five to reduce the heat accumulation inside the heat insulation cavity three.

[0011] In a preferred embodiment, a heat insulation plate 1 is installed on the upper end of the lower mold base, and a lower mold is installed on the upper side of the heat insulation plate 1. A heat insulation plate 2 is installed on the lower end of the upper mold base, and a lower mold is installed on the lower side of the heat insulation plate 2. In actual use, both heat insulation plate 1 and heat insulation plate 2 are high-temperature and high-pressure resistant hydraulic press heat insulation plates, and their specific models can be selected according to actual usage requirements.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting the base and the lower mold base, the entire base and the lower mold base will not gradually increase in heat due to the accumulation of time, thus achieving a certain degree of heat insulation, avoiding workers from being burned, and solving the problem that conventional heat insulation materials are easily aged and fall off when exposed to high temperature environment for a long time, which leads to a decrease in heat insulation effect, thus ensuring the heat insulation effect of the equipment.

[0013] 2. By setting up an upper mold base, multiple reinforcing plates are interconnected through through holes, which has strong heat dissipation performance. This avoids the situation where heat accumulates after the upper mold base has been working for a long time, causing the temperature to rise continuously and easily burn workers. It achieves heat blocking and prevents heat from being transferred to the four guide pillars after the temperature of the upper mold base rises, effectively improving the heat blocking effect.

Detailed Implementation

[0020] 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.

[0021] As the first embodiment of this utility model: Please see Figures 1 to 4A heat insulation structure for a hydraulic molding machine includes: a base 100, a lower mold base 200 for mounting a lower molding die mounted on the upper side of the base 100, an upper mold base 300 for mounting an upper die movably mounted on the upper side of the lower mold base 200 via four guide pillars and a top seat, a heat insulation cavity 110 for blocking heat transfer is respectively provided inside the left and right sides of the base 100, a heat insulation cavity 210 is provided inside the lower mold base 200 for blocking the heat after the lower mold is heated from being transferred to the lower mold base 200, and a heat insulation cavity 310 is provided inside the upper mold base 300 for blocking the heat after the upper mold is heated from being transferred to the lower mold base 200.

[0022] A heat dissipation hole 111 is formed through the left and right sides of the heat insulation cavity 110. The two heat dissipation holes 111 are arranged in an axially symmetrical structure and their centers are collinear. A heat dissipation hole 2 112 is formed through the top of the heat dissipation hole 111. In actual use, the setting of the heat insulation cavity 110 can reduce the heat accumulation after the base 100 is heated and also reduce the speed of heat transfer from the upper side.

[0023] The heat insulation cavity 210 is equipped with multiple reinforcing plates 220 arranged in a cross shape to enhance the pressure resistance of the lower mold base 200. Each of the multiple reinforcing plates 220 has a through hole in the middle. The top inner wall of the heat insulation cavity 210 is equipped with a heat insulation plate. The heat insulation cavity 210 can prevent a large amount of heat from being transferred to the lower mold base 200 and can form a certain blocking effect.

[0024] The bottom of the second heat insulation cavity 210 is provided with a connecting hole for connecting the second heat dissipation hole 112. The left and right sides of the second heat insulation cavity 210 are respectively provided with a third heat dissipation hole 230 to reduce the heat accumulation inside the second heat insulation cavity 210.

[0025] Specifically, by setting up a base 100 and a lower mold base 200, in actual use, when the lower mold is heated during operation, its heat insulation plate blocks part of the heat from being transferred to the lower mold base 200. However, over time, some heat is transferred to the lower mold base 200. At this time, because the lower mold base 200 has a heat insulation cavity 210 inside, and multiple reinforcing plates 220 are interconnected through through holes, it ensures the pressure-bearing capacity of the lower mold base 200 while also having strong heat dissipation performance. This prevents heat accumulation in the lower mold base 200 after prolonged operation, which could lead to a continuous rise in temperature and potentially burn workers. The base 100 is also equipped with a heat insulation cavity 110 and heat dissipation holes 111 for heat dissipation. At the same time, it is connected to the heat insulation cavity 210 through heat dissipation holes 112 and connecting holes, which can enhance the heat dissipation inside the heat insulation cavity. This prevents the entire base 100 and the lower mold base 200 from gradually increasing in heat over time, thus achieving a certain degree of heat insulation and preventing workers from being burned. This solves the problem that conventional methods of adding heat insulation materials to the surface of equipment to slow down the heat conduction speed are prone to aging and falling off when the heat insulation materials are exposed to high temperature environments for a long time, resulting in a decrease in the heat insulation effect. This ensures the heat insulation effect of the equipment.

[0026] As a second embodiment of this utility model: Please see Figures 1 to 4 The heat insulation cavity 310 has multiple reinforcing plates 320 arranged in a cross shape to enhance the pressure resistance of the upper mold base 300. Each of the multiple reinforcing plates 320 has a through hole in the middle. The bottom inner wall of the heat insulation cavity 310 is provided with a heat insulation plate. In actual use, the heat insulation cavity 310 can prevent a large amount of heat from being transferred to the upper mold base 300 and can form a certain blocking effect.

[0027] The top of the heat insulation cavity 310 has multiple circular heat dissipation holes 330. The left and right sides of the heat insulation cavity 310 are respectively provided with a heat dissipation hole 340 to reduce the heat accumulation inside the heat insulation cavity 310.

[0028] A heat insulation plate 1 is installed on the upper end of the lower mold base 200, and a lower mold is installed on the upper side of the heat insulation plate 1. A heat insulation plate 2 is installed on the lower end of the upper mold base 300, and a lower mold is installed on the lower side of the heat insulation plate 2. In actual use, both heat insulation plate 1 and heat insulation plate 2 are high temperature and high pressure resistant hydraulic press heat insulation plates, and their specific models can be selected according to actual use requirements.

[0029] Based on the first embodiment described above, further, by setting the upper mold base 300, in actual use, when the upper mold is heated during operation, its heat insulation plate 2 blocks part of the heat from being transferred to the upper mold base 300. As time goes by, some heat will be transferred to the upper mold base 300. At this time, since the upper mold base 300 is provided with a heat insulation cavity 210 and is interconnected with multiple reinforcing plates 320 through through holes 2, it has strong heat dissipation performance. This avoids the situation where heat accumulates after the upper mold base 300 has been working for a long time, causing the temperature to rise continuously and easily burn workers. This achieves heat blocking and prevents heat from being transferred to the four guide pillars after the temperature of the upper mold base 300 rises, effectively improving the heat blocking effect.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
