[0038] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0039] like Figure 1-3 As shown, a hoisting device for a mold is used for hoisting a mold 100, the mold 100 includes a first mold body and a second mold body, and a metering pump 200 is connected to the second mold body, including:

[0040] Lifting bracket 300;

[0041] A first moving part 410, a second moving part 420 and a third moving part 430, wherein the first moving part 410, the second moving part 420 and the third moving part 430 are slidably mounted on the hanging bracket 300;

[0042] The first moving part 410 is connected to the metering pump 200, and the first moving part 410 is suitable for being driven to drive the metering pump 200 away from the first mold body and the second mold body after the first mold body and the second mold body are separated from the metering pump 200;

[0043] The second moving part 420 is connected to the first mold body, and the third moving part 430 is connected to the second mold body;

[0044] The second moving part 420 and the third moving part 430 are adapted to separate the first mold body and the second mold body after the metering pump 200 is separated from the first mold body and the second mold body.

[0045] In this embodiment, if Figure 1-3 As shown, when it is necessary to clean the residual material in the inner cavity of the mold 100, the first mold body and the second mold body only need to be connected to the second moving part 420 and the third moving part 430 respectively. Then, the connecting screws between the mold 100 and the distributor are removed, and the stopper is disengaged. Considering that the distributor flow channel may sag or fall due to its heavy weight, the first moving part 410 is set above the metering pump 200 to effectively avoid such unsafe factors.

[0046] Next, the metering pump 200 is separated from the mold 100, and the mold 100 is moved forward. Since the mold 100 has two parts, namely the first mold body and the second mold body, both of which are separately connected to the independent second moving part 420 and the third moving part 430, the mold can be separated while being hoisted, that is, the first mold body and the second mold body can be separated. Then, the worker can use professional tools to clean the residual materials in the inner cavity of the mold 100.

[0047] After the residual material is cleaned up, just merge the first mold body and the second mold body, then retreat to the position of the metering pump 200, and then fix the screw connection. This series of processes greatly improves production efficiency. At the same time, when the production line is just started, in order to prevent the grease and iron filings in the screw barrel of the extruder from scratching or jamming the metering pump 200 and the inside of the mold 100 during flushing, when the mold 100 is cleaned by hoisting, the metering pump 200 and the mold 100 will be disengaged from the screen changer, and the material can be squeezed out of the screen changer during cleaning. In this way, the metering pump 200 and the mold 100 can be effectively protected to avoid danger. The metering pump 200 is connected to the distributor flow channel, and the metering pump 200 is provided with a pair.

[0048] Specifically, Figure 1-3 As shown, the mold hoisting device further includes a slide rail guide assembly, and the first moving part 410, the second moving part 420 and the third moving part 430 slide on the hoisting bracket 300 through the slide rail guide assembly. The slide rail guide assembly can be the following structure:

[0049] Guide rail 510, guide rail 510 is fixedly mounted on the hanging bracket 300;

[0050] Roller group 520, the roller group 520 is arranged at the bottom of both sides of the first moving part 410, the second moving part 420 and the third moving part 430;

[0051] The roller assembly 520 is suitable for rolling along the guide rail 510 to drive the first moving part 410 , the second moving part 420 and the third moving part 430 to move on the hanging bracket 300 .

[0052] In this embodiment, if Figure 1-3 As shown, the guide rail 510 is integrally fixedly mounted on the hanging bracket 300, and the roller group 520 can increase the support area and improve the sliding stability. The roller group 520 includes a plurality of rollers, and the plurality of rollers work together to make the rolling smoother. When an external force acts on the first moving part 410, the second moving part 420 and the third moving part 430, the roller group 520 rolls on the guide rail 510, driving the mold 100 and the metering pump 200 to translate on the hanging bracket 300.

[0053] Specifically, Figure 1-3As shown, the first moving part 410, the second moving part 420 and the third moving part 430 further include a lifting connection member 600;

[0054] Both ends of the lifting connector 600 are provided with connection holes;

[0055] The first mold body, the second mold body and the top of the metering pump 200 are provided with matching holes for the lifting connector 600;

[0056] The lifting connector 600 is suitable for connecting to the first moving part 410 and the metering pump 200, the second moving part 420 and the third moving part 430 and the first mold body and the second mold body respectively through the connecting part passing through the connecting hole and the matching hole.

[0057] In this embodiment, if Figure 1 As shown, the setting of the connection hole can realize detachable connection at both ends of the hoisting connector 600. In this way, a connector, such as a bolt, is passed through the connection hole and the matching hole to realize fixed connection. When disassembly is required, the hoisting connector 600 can be disconnected from the metering pump 200, the first mold body and the second mold body by using a disassembly tool. Therefore, the setting of the hoisting connector 600 and its connection hole and matching hole realizes the detachable connection of the metering pump 200, the first mold body and the second mold body. It can be hoisted by the hoisting connector 600, and it can also be conveniently disassembled when needed, which expands the application range of the hoisting device.

[0058] Specifically, Figure 1-3 As shown, longitudinal adjustment grooves extending longitudinally are provided on the first moving part 410, the second moving part 420 and the third moving part 430;

[0059] One end of the lifting connector 600 is detachably mounted on the longitudinal adjustment slots of the first moving part 410, the second moving part 420 and the third moving part 430 through the connector;

[0060] The hanging connection piece 600 is suitable for driving the metering pump 200, the first mold body and the second mold body to adjust their longitudinal positions on the hanging bracket 300 by moving longitudinally in the longitudinal adjustment groove.

[0061] In this embodiment, if Figure 1 As shown, the longitudinal adjustment slot enhances the application scope of the lifting, makes the use more flexible and convenient, and provides a positioning and installation function for molds 100 of different sizes.

[0062] Specifically, Figure 1-3 As shown, there are two longitudinal adjustment slots on the first moving part 410, the second moving part 420 and the third moving part 430;

[0063] The lifting connector 600 is provided with two corresponding longitudinal adjustment slots on each of the first moving part 410 , the second moving part 420 and the third moving part 430 ;

[0064] The two lifting connectors 600 are detachably mounted on the corresponding longitudinal adjustment slots through connectors.

[0065] In this embodiment, if Figure 1-3 As shown, the two hanging connectors 600 can balance and stabilize the mold 100 and the metering pump 200 on the hanging bracket 300 .

[0066] Specifically, Figure 1-3 As shown, a supporting platform 700 suitable for carrying the metering pump 200 is also provided on the hanging bracket 300 .

[0067] In this embodiment, if Figure 1-3 As shown, the lifting bracket 300 is provided with two layers of horizontal square steels, the first movable part 410 , the second movable part 420 and the third movable part 430 are installed on the square steel of the upper layer, and the supporting platform 700 is installed on the square steel of the lower layer. There are two supporting platforms 700 corresponding to the metering pumps 200 .

[0068] Specifically, Figure 1-2 As shown, a limiting column is provided on the support platform 700;

[0069] The limiting column is suitable for limiting and relatively fixing the position of the metering pump 200 on the supporting platform 700 .

[0070] In this embodiment, if Figure 1-3 As shown, the limiting column is a short column erected on the surface of the support platform 700, and its height is suitable for blocking the edge of the metering pump 200. When the first moving part 410 places the metering pump 200 on the support platform 700, the edge of the metering pump 200 can be made to abut against the limiting column by adjusting the position, and the metering pump 200 will be blocked by the limiting column and cannot continue to move, which plays a positioning role. The use of limiting columns can easily and quickly realize the positioning of the metering pump 200 on the support platform 700, avoiding the occurrence of position offset. At the same time, the reasonable arrangement of multiple limiting columns can also realize the angular positioning of the metering pump 200. Compared with placing it directly on the platform, setting the limiting column achieves a better fixing effect on the metering pump 200. This ensures that the metering pump 200 will not move or tip over during temporary storage, greatly reducing safety hazards.

[0071] Specifically, Figure 1-3 As shown, a support foot 800 is provided at the bottom of the hanging bracket 300;

[0072] The supporting foot 800 is provided with a fixing hole.

[0073] In this embodiment, if Figure 1-3 As shown, considering the heavy weight of the hanging bracket 300 and the components it carries, if it is directly placed on the ground for use, it may tilt or sink, affecting the stability of the hanging. In order to enhance the supporting effect on the ground, a supporting foot 800 is set at the bottom of the hanging bracket 300. The supporting foot 800 is fixedly connected to the bottom of the hanging bracket 300 to support the hanging bracket 300. In order to further enhance the fixing effect on the ground or other bearing surfaces, a fixing hole is also provided on the supporting foot 800. During operation, the supporting foot 800 can be fixed to the ground through the fixing hole using bolts and other fixing parts to prevent the entire device from shifting or tipping over. The setting of the supporting foot 800 enhances the overall stability of the hanging bracket 300 and avoids tilting due to excessively high center of gravity. At the same time, the design of the fixing hole enables the supporting foot 800 to be reliably connected to the ground, greatly improving the safety of use. This is very necessary to ensure that the hanging can work smoothly and safely.

[0074] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
