Description

Technical Field

[0001] This utility model relates to the field of mold temperature control technology, and in particular to a device that can improve the temperature uniformity of molds. Background Technology

[0002] Heated molds are key equipment in industrial production for material forming. Their core principle is to achieve and maintain the required process temperature through energy conversion and heat transfer, combined with precise temperature control. Currently, the two most common mold heating methods are oil heating and electric heating. Oil-heated molds offer good temperature uniformity within the mold cavity, but are prone to environmental pollution due to oil leakage, and require preheating of the oil medium, resulting in a long start-up time. In contrast, electric-heated molds do not have the problem of oil pollution and offer a faster heating rate.

[0003] However, electrically heated molds also have a fatal flaw: poor temperature uniformity, with no heat dissipation in the middle, resulting in significantly higher temperatures during continuous heating. Utility Model Content

[0004] The purpose of this invention is to provide a device that can improve the temperature uniformity of a mold, which can adjust the heat dissipation efficiency of various parts of the mold as needed, thereby improving the temperature uniformity of the mold.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is: a device that can improve the temperature uniformity of a mold, including a number of columnar radiators that are vertically installed on the upper surface of the mold and can adjust the heat dissipation efficiency, and the number of columnar radiators are evenly distributed on the entire upper surface of the mold; it also includes a heat insulation board attached to the side surface of the mold.

[0006] As a further improvement of this utility model, the columnar radiator includes a heat-conducting column arranged along its axial direction, the lower end of the heat-conducting column is fixedly connected to the mold, and the heat-conducting column is sleeved with a heat insulation tube that is clearance-fitted to it. An air inlet is provided on the lower side wall of the heat insulation pipe, and an adjustment plug that can be adjusted up and down is inserted into the upper end of the heat insulation pipe. The lower side wall of the adjustment plug and the inner wall of the heat insulation pipe are sealed with a conical surface.

[0014] Beneficial effects Compared with the prior art, the advantages of the device of this utility model that can improve the temperature uniformity of the mold are as follows: The device features columnar heat sinks evenly distributed across the upper surface of the mold, with adjustable heat dissipation efficiency. By adjusting the efficiency of each columnar heat sink, the heat dissipation rate in the high-temperature zone at the center of the mold can be increased while maintaining or decreasing the heat dissipation rate in the low-temperature zone at the mold edge. This ensures that the temperature of the high-temperature zone and the non-high-temperature zone of the mold remains as consistent as possible, thereby improving the overall temperature uniformity of the mold. Furthermore, by attaching insulation plates to the side surfaces of the mold, the heat dissipation rate in the low-temperature zone can also be reduced, further ensuring that the temperature of the high-temperature zone and the non-high-temperature zone remains as consistent as possible.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0022] Example: The specific embodiments of this utility model are as follows: Figure 1 As shown, a device for improving the temperature uniformity of a mold includes several vertically mounted columnar radiators 1 on the upper surface of the mold 5, which are adjustable in heat dissipation efficiency. In this embodiment, the columnar radiators 1 are arranged in a rectangular array and evenly distributed across the entire upper surface of the mold 5. Furthermore, the device also includes insulation plates 6 attached to the side surfaces of the mold 5.

[0023] In use, first adjust the heat dissipation efficiency of each columnar heat sink 1 according to the distribution of the high-temperature zone of the mold 5. Taking this embodiment as an example, since the middle of the mold 5 is a high-temperature zone, increase the heat dissipation efficiency of the columnar heat sink 1 in the middle of the upper surface of the mold 5 to enable it to dissipate heat faster. At the same time, maintain or reduce the heat dissipation efficiency of the columnar heat sink 1 around the upper surface of the mold 5 to maintain or reduce the heat dissipation rate around the upper surface of the mold 5. Furthermore, attach a heat insulation plate 6 to the side surface of the mold 5 to further reduce the heat dissipation rate of the low-temperature zone at the edge of the mold 5.

[0024] Therefore, this device can keep the temperature of the high-temperature zone and the non-high-temperature zone of the mold 5 as consistent as possible, thereby improving the overall temperature uniformity of the mold 5.

[0025] Regarding the structure of columnar radiator 1, as follows: Figure 2 As shown, the columnar heat sink 1 includes a heat-conducting column 3 arranged along its axial direction. The lower end of the heat-conducting column 3 is fixedly connected to the mold 5, allowing heat from the mold 5 to be transferred into the columnar heat sink 1. Simultaneously, a heat-insulating tube 2, with a clearance fit, is fitted around the heat-conducting column 3 to prevent heat from radiating to the surrounding area of ​​the columnar heat sink 1, thus preventing interference with the normal operation of adjacent columnar heat sinks 1. In this embodiment, the overall height of the columnar heat sink 1 is 200mm-300mm.

[0026] To achieve adjustable heat dissipation, an air inlet 21 is provided on the lower side wall of the heat insulation pipe 2, and an adjustable plug 4, capable of vertical adjustment, is inserted into the upper end of the heat insulation pipe 2. The lower side wall of the adjustable plug 4 and the inner wall of the heat insulation pipe 2 are sealed with a conical surface. Furthermore, the top of the adjustable plug 4 is provided with an air outlet channel 41 extending downwards to its sealing conical surface. In this embodiment, there are multiple air inlets 21, and these multiple air inlets 21 are symmetrically arranged around the axis of the heat insulation pipe 2. There are multiple air outlet channels 41, and these multiple air outlet channels 41 are symmetrically arranged around the axis of the adjustable plug 4.

[0027] By moving the adjusting plug 4 upwards, a gap is created between the lower sidewall of the adjusting plug 4 and the inner wall of the heat insulation pipe 2, thus connecting the air outlet duct 41 with the air inlet 21. When the air outlet duct 41 is connected to the air inlet 21, a chimney effect is generated inside the columnar radiator 1, causing airflow to pass through the gap between the heat-conducting column 3 and the heat insulation pipe 2, thereby carrying away the heat on the heat-conducting column 3. Furthermore, as the adjusting plug 4 is moved further upwards, the gap between the lower sidewall of the adjusting plug 4 and the inner wall of the heat insulation pipe 2 increases, which can further increase the airflow of the air outlet duct 41, thereby improving the heat dissipation efficiency of the columnar radiator 1. Similarly, if the adjusting plug 4 is moved downwards, the heat dissipation efficiency of the columnar radiator 1 can be reduced until the air outlet duct 41 no longer dissipates air for heat dissipation. Thus, the columnar radiator 1 can achieve adjustable heat dissipation efficiency.

[0028] To connect the heat-conducting pillar 3 to the mold 5, the heat-conducting pillar 3 is fixedly connected to the mold 5 via a fixed base 31, which is an integral structure with the heat-conducting pillar 3, located at its lower end. Specifically, the fixed base 31 is fixedly connected to the mold 5 with screws. Simultaneously, to improve the heat conduction efficiency of the heat-conducting pillar 3, a copper sheet is placed between the fixed base 31 and the mold 5 for heat conduction, thereby enhancing its thermal conductivity.

[0029] To achieve a fixed connection between the heat-conducting column 3 and the heat insulation pipe 2, the heat-conducting column 3 is also fixedly connected to the heat insulation pipe 2 via a cross-shaped connector 33 located at its upper end. Specifically, the cross-shaped connector 33 is threadedly connected to the heat insulation pipe 2 via an external thread on its protruding end face. The cross-shaped connector 33 is used because this structure of connector does not affect the airflow.

[0030] To further improve heat dissipation efficiency, heat-conducting fins 32 are also provided on the outer wall of the middle part of the heat-conducting column 3. Through the heat-conducting fins 32, the airflow can better remove the heat from the heat-conducting column 3, thereby improving the heat dissipation efficiency of the columnar radiator 1.

[0031] Furthermore, regarding how the vertical position of the adjusting plug 4 is adjustable, in this embodiment, the upper sidewall of the adjusting plug 4 is threadedly connected to the inner wall of the insulation pipe 2. This threaded connection allows for vertical adjustment of the adjusting plug 4 by turning it, with high precision. Correspondingly, to accommodate this structure, a conical sealing portion 42 with a gradually increasing cross-sectional area from top to bottom is provided at the lower part of the adjusting plug 4. The sidewall of the conical sealing portion 42 forms a conical surface seal with the inner wall of the insulation pipe 2.

[0032] In addition, it is important to note that: In this embodiment, the heat insulation pipe 2 is a ceramic pipe; the adjusting plug 4 is a ceramic plug. Of course, in actual production, the heat insulation pipe 2 and the adjusting plug 4 can also be made of other heat insulation materials. This design is to reduce the thermal conductivity of the heat insulation pipe 2 and the adjusting plug 4 themselves, so that when the adjusting plug 4 and the heat insulation pipe 2 are sealed together without air flow, there will be no significant heat loss, thereby improving the controllability of heat dissipation efficiency.

[0033] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
