Please refer to Figure 7 The second housing 200 is installed in cooperation with the first housing 100 to define a first accommodating chamber 500 and a second accommodating chamber 600. The first accommodating chamber 500 is arranged in an annular shape around the second accommodating chamber 600, and the first accommodating chamber 500 is communicated with the second accommodating chamber 600. The heating element 300 is arranged on the first housing 100 and the second housing 200. The injection piece 400 can pass through the first accommodating chamber 500 and be inserted into the second accommodating chamber 600 to block the air flow passage between the first accommodating chamber 500 and the second accommodating chamber 600, and the injection piece 400 is used to inject material into the second accommodating chamber 600 at a preset air pressure. The heating element 300 can heat the material injected into the second accommodating cavity 600, can accelerate the speed of solidification of the material, and can improve the pouring speed. The injection element 400 is used to inject the material into the second accommodating cavity 600 at the preset air pressure, and can provide injection pressure for the material to be injected into the second accommodating cavity 600. On the one hand, it can effectively improve the defects of bubbles and partial missing of the product after pouring and molding, and improve the quality of the product after pouring and molding. On the other hand, the injection pressure can accelerate the speed of injecting the material into the second accommodating cavity 600, accelerate the pouring speed, and improve the efficiency of pouring.

[0036] See also Figure 2 and Figure 3In some embodiments, the first shell 100 includes: a bearing portion 110 and an enclosure portion 120. The bearing portion 110 is arranged along a first preset direction. The enclosure portion 120 is arranged along a second preset direction. The second preset direction is perpendicular to the first preset direction. The enclosure portion 120 is arranged on the bearing portion 110, and the enclosure portion 120 is arranged in an annular shape around the periphery of the bearing portion 110. The enclosure portion 120 is connected to the bearing portion 110, and the bearing portion 110, the enclosure portion 120 and the second shell 200 form the first accommodating cavity 500 and the second accommodating cavity 600.

[0037] In some embodiments, the second accommodating cavity 600 is a casting cavity, and the second accommodating cavity 600 has a preset shape. The preset shape is the shape of the material after casting, and the preset shape can be adjusted according to actual needs.

[0038] In some embodiments, the heating element 300 is a heating rod, and the heating element 300 is disposed in the carrier.

[0039] It can be understood that the first accommodating cavity 500 surrounding the second accommodating cavity 600 can slow down the heat loss in the second accommodating cavity 600 and play a role in heat preservation, thereby accelerating the curing and molding speed of the material in the second accommodating cavity 600 and improving the casting efficiency.

[0040] See also Figure 3 In some embodiments, the enclosure 120 is provided with a first interface 121 and a second interface 122. The first interface 121 is provided at one side of the enclosure 120, and the number of the first interfaces 121 is two, and the first interface 121 is a vacuum port. The second interface 122 is provided at a side of the enclosure 120 away from the first interface 121, and the number of the second interface 122 is one, and the second interface 122 is a material injection port.

[0041] In other embodiments, the number of the first interfaces 121 may be adjusted to three, four, five, six, etc. according to actual needs, which will not be listed here one by one.

[0042] See also Figure 3 and Figure 7 In some embodiments, a suction piece 700 is disposed in the first interface 121. The suction piece 700 passes through the first interface 121 and is inserted into the first accommodating cavity 500. The suction piece 700 is used to perform a vacuum process on the first accommodating cavity 500. The injection piece 400 passes through the second interface 122 and is inserted into the second accommodating cavity 600.

[0043] See also Figure 1 and Figure 2 In some embodiments, the suction member 700 includes: a vacuum valve 710 and a vacuum pump. The vacuum valve 710 is a solenoid valve, and the vacuum valve 710 has an input end and an output end. The input end is connected to the vacuum pump. The output end passes through the first interface 121 and extends into the first accommodating chamber 500.

[0044] It is understandable that the vacuum pump is started and the flow of the vacuum valve 710 is adjusted so that the first vacuum degree in the first accommodating chamber 500 can be adjusted according to actual needs, and the second accommodating chamber 600 is connected to the first accommodating chamber 500, so that the second vacuum degree in the second accommodating chamber 600 can be adjusted synchronously and the second vacuum degree can be equal to the first vacuum degree. The first accommodating chamber 500 in a vacuum can further slow down the heat loss rate in the second accommodating chamber 600, enhance the thermal insulation performance, and improve the sealing of the second accommodating chamber 600, and enable the second accommodating chamber 600 to be poured in a vacuum environment.

[0045] In some embodiments, the pouring equipment further comprises: a pouring tank. The material is stored in the pouring tank, and a discharge valve is provided on the pouring tank. The discharge valve is a solenoid valve, which is connected to the injection piece 400 and is used to control the amount of the material output from the pouring tank to the injection piece 400.

[0046] It can be understood that, compared with the traditional method of transporting materials through pipelines, transporting materials through the pouring tank can reduce the use of pipelines, thereby reducing the maintenance work of the pipelines.

[0047] See also Figure 6 and Figure 7 In some embodiments, the injection piece 400 includes a plug end 410 and a driving end. When the first vacuum degree and the second vacuum degree are both equal to the preset vacuum degree, the plug end 410 sequentially passes through the second interface 122 and the first accommodating cavity 500 and is inserted into the second accommodating cavity 600. The driving end is connected to the discharge valve.

[0048] In other embodiments, when the first vacuum degree is equal to the preset vacuum degree, or when the second vacuum degree is equal to the preset vacuum degree, the plug-in end 410 is inserted into the second accommodating cavity 600 .

[0049] In some embodiments, the pouring tank is connected to an air source, which is compressed air, and the air source drives the material in the pouring tank to pass through the discharge valve, the drive end, and the plug end 410 in sequence, and is output from the plug end 410 to the second accommodating cavity 600 .

[0050] It can be understood that by driving the material to be injected into the second accommodating cavity 600 by compressed air, the injection speed can be accelerated and the casting efficiency can be improved.

[0051] See also Figure 3 In some embodiments, the enclosure 120 includes: a first enclosure 123 and a second enclosure 124. The first enclosure 123 is connected to the bearing portion 110, and the bearing portion 110, the first enclosure 123 and the second shell 200 form the first accommodating cavity 500, and the first enclosure 123 is arranged in an annular manner around the second enclosure 124. The second enclosure 124 is arranged in an annular manner around the central axis of the bearing portion 110.

[0052] In some embodiments, the first enclosure portion 123 is two enclosure sheets arranged opposite to each other. The second interface 122 is arranged at the connection between the two enclosure sheets.

[0053] In some embodiments, the second enclosure portion 124 is a conductor, a central axis of the second enclosure portion 124 coincides with a central axis of the first enclosure portion 123 , and the second enclosure portion 124 is circular.

[0054] See also Figure 4 and Figure 5 In some embodiments, the second shell 200 includes: a cover portion 210 and a protrusion 220. The cover portion 210 is arranged opposite to the bearing portion 110. The heating element 300 is also arranged in the cover portion 210. The protrusion 220 is arranged on a side of the cover portion 210 close to the bearing portion 110, and the protrusion 220 is inserted into the first enclosure portion 123 to form the first accommodating cavity 500 with the first enclosure portion 123 and the bearing portion 110, and to form the second accommodating cavity 600 with the second enclosure portion 124 and the bearing portion 110.

[0055] In some embodiments, the cover portion 210, the protrusion 220, the enclosure portion 120 and the support portion 110 are all made of heat-conductive materials. When the heating element 300 in the cover portion 210 and the enclosure portion 120 is in operation, the heat generated by the heating element 300 can be conducted to the first accommodating cavity 500 and the second accommodating cavity 600, so as to speed up the casting and molding of the material.

[0056] In some embodiments, a recessed area is provided on the protruding portion 220. The recessed area is recessed in a direction away from the second enclosure portion 124 to form a groove 221. When the protruding portion 220 is inserted into the first enclosure portion 123, an end of the second enclosure portion 124 away from the bearing portion 110 is inserted into the groove 221 to form the second accommodating cavity 600.

[0057] See also Figure 5 In some embodiments, the protrusion 220 is provided with a guide channel 222. The guide channel 222 is connected to the second accommodating cavity 600. The plug end 410 passes through the guide channel 222.

[0058] In some embodiments, the central axis of the recessed area coincides with the central axis of the protruding portion 220 .

[0059] See also Figure 3 and Figure 4 In some embodiments, the first shell 100 further includes a first heat preservation portion 130. The first heat preservation portion 130 is disposed on the bearing portion 110, and the first heat preservation portion 130 is disposed in an annular manner around the enclosure portion 120. The second shell 200 further includes a second heat preservation portion 230, the second heat preservation portion 230 is disposed on the cover portion 210, and the second heat preservation portion 230 is disposed in an annular manner around the protrusion 220. The bearing portion 110, the first heat preservation portion 130, the second heat preservation portion 230 and the cover portion 210 form a heat preservation cavity, and the heat preservation cavity is disposed in an annular manner around the first accommodating cavity 500, which can play a heat preservation role for the first accommodating cavity 500 and the second accommodating cavity 600.

[0060] See also Figure 1 and Figure 2 In some embodiments, the pouring equipment further includes: a connecting frame 800. The connecting frame 800 connects the cover plate portion 210 and the bearing portion 110, so that the cover plate portion 210 and the bearing portion 110 are detachably connected, and the first heat preservation portion 130 abuts against the second heat preservation portion 230, and the end of the second enclosure portion 124 away from the bearing portion 110 abuts against the groove 221.

[0061] In some embodiments, the pouring equipment further includes: a control component. The control component is connected to the heating component 300, the vacuum pump, the vacuum valve 710 and the discharge valve, and is used to control the operation of the heating component 300, the vacuum pump, the vacuum valve 710 and the discharge valve, and the control component can control the temperature of the heating component in different areas, so as to adjust the temperature of one or more areas of the second accommodating chamber 600.

[0062] It is understandable that the temperature, vacuum degree and injection speed can be adjusted according to actual needs through the control component to be suitable for the casting of different products.

[0063] Traditional multi-cavity casting molds use a method of heating the entire casting mold, which makes it difficult to accurately adjust the temperature of each area of ​​the casting mold, and it needs to be moved to the heating area for heating before the casting is completed, resulting in low casting efficiency. However, the casting equipment in the present application has a heating element 300 on both the first shell 100 and the second shell 200, which has its own heating function and can directly heat the casting cavity. The heat conduction efficiency is high, which improves the casting efficiency. By controlling the heating element 300, the temperature of a single casting cavity can be accurately controlled, that is, the temperature of a single casting cavity can be adjusted according to actual needs, thereby increasing the application scope of the casting equipment. In addition, the casting equipment also has the functions of preheating, casting and curing, that is, during the entire casting process, there is no need to open the first shell 100 and the second shell 200 to transfer the casting to different processes, thereby ensuring the continuity of the casting and high casting efficiency.

[0064] The present application heats the cover plate portion 210 and the bearing portion 110 through the heating element 300 to increase the temperature of the first accommodating cavity 500 and the second accommodating cavity 600, thereby accelerating the molding speed of the material in the second accommodating cavity 600 and improving the pouring efficiency. In addition, the compressed air of the pouring tank drives the material to be injected into the second accommodating cavity 600, which can accelerate the speed of injecting the material into the second accommodating cavity 600 and further improve the pouring efficiency.
