Description

Technical Field

[0001] This utility model relates to the field of plastic molding technology, specifically to a plastic parts molding equipment that facilitates demolding. Background Technology

[0002] Plastic molding equipment is a key piece of equipment in the plastics processing industry used to process plastic raw materials into plastic parts of specific shapes and sizes. It covers a variety of types such as injection molding, blow molding, and extrusion molding, and is widely used in automobile manufacturing, electronics, medical devices and other fields.

[0003] Molding equipment can injection mold molten plastic raw materials into plastic parts. However, existing plastic parts are molded inside the molding equipment using only a single circulating water cooling method. In order to maintain a stable cooling effect, the equipment often needs to be equipped with large-scale cooling equipment, such as cooling towers and cooling water pump sets. This not only significantly increases the initial purchase cost of the equipment, but also consumes a lot of electricity and water resources during long-term operation. Furthermore, over-cooling can cause large internal stresses in the plastic parts, resulting in uneven shrinkage and deformation during the cooling process. This makes it difficult to demold quickly in the later stages and inconvenient for personnel to use. Summary of the Invention

[0004] The purpose of this invention is to provide a plastic part molding device that facilitates demolding, so as to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a plastic part molding device for easy demolding, comprising a support plate one; a molding mold is installed at the center of one end of the support plate one, a demolding mechanism is installed inside the molding mold, a transmission mechanism is installed on the side of the demolding mechanism, a cooling frame is installed on the outside of the molding mold, a cooling frame is installed at the bottom of the cooling frame, a rotating shaft is rotatably installed inside the cooling frame, a power pump is installed on one side of the rotating shaft, the output end of the power pump is connected to the cooling frame, a drive mechanism is installed at the four corners of the support plate one on the outside of the cooling frame, a molding mechanism is driven and installed on the outside of the drive mechanism, and a support plate two is installed at the end of the molding mechanism away from the cooling frame.

[0006] Preferably, the demolding mechanism includes a top plate disposed inside the molding mold, one end of the top plate having a rack installed through the interior of the cooling frame, and one end of the rack having a drive gear installed on the back of the cooling frame.

[0007] Preferably, the transmission mechanism includes a transmission belt one disposed on one side of the power gear, a transmission shaft internally mounted below the transmission belt one, and a transmission belt two externally mounted on the transmission shaft, the transmission belt two being connected to the outer side of one end of the rotating shaft.

[0008] Preferably, the cooling frame has multiple sets of heat sinks on its outer surface near the rotating shaft, and the multiple sets of heat sinks are arranged horizontally.

[0009] Preferably, the molding mold has a molding groove inside, a top plate is movably connected inside the molding groove, and an injection port is provided inside the top of the molding mold.

[0010] Preferably, the molding mechanism includes a connecting plate disposed outside the driving mechanism, and a molding head is installed on one end of the connecting plate near the molding die.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a cooling frame, a temperature-reducing frame, a rotating shaft, a power pump, a demolding mechanism, and a transmission mechanism in combination. The coolant inside the cooling frame can cool the plastic raw material inside the molding die. At the same time, the used coolant is transported back into the temperature-reducing frame. When the demolding mechanism is working, the power is transmitted through the transmission mechanism, which can simultaneously drive the rotating shaft to rotate and dissipate the heat of the coolant inside the temperature-reducing frame. The cooled coolant is then transported back into the cooling frame by the power pump for reuse. Therefore, there is no need to add additional cooling equipment. This achieves the purpose of accelerating the molding of plastic parts and reducing sticking, while facilitating the subsequent demolding mechanism to quickly demold the parts, thus making it easier for personnel to use.

[0013] 2. This utility model uses a power gear, a rack, and a top plate in combination. The rotation of the power gear drives the rack, which meshes with it, to move linearly, thereby pushing the top plate to move within the molding mold. Then, the molded plastic part is ejected from the mold. This structure is relatively simple. When the power gear and rack mesh with each other to transmit power over a long period of time, it can withstand a large load and is not prone to deformation or damage in the later stages.

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0021] Example:

[0022] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 4 This application provides a convenient demolding plastic part molding device, please refer to it carefully. Figure 1 , Figure 2 and Figure 4 The system includes a support plate 1; a forming mold 2 is installed at the center of one end of the support plate 1; a demolding mechanism 4 is installed inside the forming mold 2; a transmission mechanism 5 is installed on the side of the demolding mechanism 4; a cooling frame 3 is installed on the outside of the forming mold 2; a cooling frame 301 is installed at the bottom of the cooling frame 3; a rotating shaft 302 is rotatably installed inside the cooling frame 301; a power pump 303 is installed on one side of the rotating shaft 302; the output end of the power pump 303 is connected to the cooling frame 3; a drive mechanism 6 is installed at the four corners of the support plate 1 on the outside of the cooling frame 3; a forming mechanism 7 is installed on the outside of the drive mechanism 6; a support plate 8 is installed at the end of the forming mechanism 7 away from the cooling frame 3; the input end of the power pump 303 is connected to the cooling frame 301; the output end of the power pump 303 is connected to the cooling frame 3; the cooling frame 3 and the cooling frame 301 are internally connected; the drive mechanism 6 is an existing threaded transmission structure that can convert rotary motion into linear motion.

[0023] Specifically, support plate 1 supports the molding mold 2, and cooling frame 3 wraps around the outside of the molding mold 2. It works in conjunction with cooling frame 301, rotating shaft 302 and power pump 303 to form the cooling system of the equipment. The rotation of rotating shaft 302 inside cooling frame 301 can accelerate the flow of coolant. With the help of power pump 303, coolant is delivered to cooling frame 3 to cool molding mold 2, ensuring that plastic parts are molded at a suitable temperature. This avoids quality problems such as product deformation caused by excessive temperature, while extending the service life of the mold and accelerating the molding of plastic parts. It also facilitates demolding by demolding mechanism 4. The drive mechanism 6 installed at the four corners of the outside of cooling frame 3 provides power to molding mechanism 7, driving molding mechanism 7 to complete the shaping of plastic raw materials. Support plate 2 provides support at the other end of molding mechanism 7 to ensure stable molding operation.

[0024] Please refer to this carefully. Figure 1 and Figure 2 The demolding mechanism 4 includes a top plate 403 disposed inside the molding mold 2. One end of the top plate 403 passes through the interior of the cooling frame 3 and is fitted with a rack 402. One end of the rack 402 is located on the back of the cooling frame 3 and is fitted with a power gear 401. The power gear 401 consists of a motor and a gear disk, and the output end of the motor is connected to the gear disk.

[0025] Specifically, in order to demold the plastic parts formed inside the molding mold 2, the top plate 403 is movably disposed inside the molding mold 2. It is the core component that directly contacts the plastic parts and completes the ejection action. When demolding is required, the power gear 401 rotates, driving the rack 402 that meshes with it to move linearly, thereby pushing the top plate 403 to move inside the molding mold 2 and ejecting the molded plastic parts from the mold.

[0026] Please refer to this carefully. Figure 2 and Figure 3 The transmission mechanism 5 includes a transmission belt 501 disposed on one side of the power gear 401, a transmission shaft 502 internally mounted below the transmission belt 501, and a transmission belt 503 externally mounted on the transmission shaft 502. The transmission belt 503 is connected to the external side of one end of the rotating shaft 302. The transmission is a gear tooth friction transmission method, which is the prior art.

[0027] Specifically, in order to transmit the power source, the power of the power gear 401 is transmitted to the drive shaft 502 through the first drive belt 501. The drive shaft 502 then transmits the power to the rotating shaft 302 through the second drive belt 503. The rotation of the rotating shaft 302 can cause the heat of the coolant inside the cooling box 301 to dissipate.

[0028] Please refer to this carefully. Figure 1The cooling frame 301 has multiple sets of heat sinks 304 on its outer surface near the rotating shaft 302, and the multiple sets of heat sinks 304 are arranged horizontally.

[0029] Specifically, in order to improve the heat dissipation effect of the coolant inside the cooling frame 301, the heat dissipation surface area of ​​the cooling frame 301 is increased by the heat sink 304, which significantly improves the heat exchange efficiency and can dissipate the heat inside the cooling frame 301 to the surrounding environment more quickly. In addition, the multiple sets of horizontally arranged heat sinks 304 increase the contact area with the air and form more heat dissipation channels.

[0030] Please refer to this carefully. Figure 1 and Figure 2 The molding mold 2 has a molding groove 201 inside, and a top plate 403 is movably connected inside the molding groove 201. The top of the molding mold 2 has an injection port 202 inside.

[0031] Please refer to this carefully. Figure 2 The molding mechanism 7 includes a connecting plate 701 disposed outside the driving mechanism 6, and a molding head 702 is installed on one end of the connecting plate 701 near the molding mold 2.

[0032] Specifically, in order to mold the plastic part, the power generated by the drive mechanism 6 is transmitted to the molding head 702 through the connecting plate 701, so that the molding head 702 can move according to the predetermined trajectory and force. Under the drive of the drive mechanism 6, the molding head 702 can accurately cooperate with the molding mold 2. At this time, the molten plastic can be accurately injected into the molding tank 201 through the injection port 202. The molten plastic material will be molded inside the molding tank 201. After the plastic part is molded, the molded plastic part can be ejected from the molding tank 201 by the movement of the top plate 403, realizing fast and convenient demolding.

[0033] Working principle: The power generated by the drive mechanism 6 is transmitted to the molding head 702 via the connecting plate 701. Under the drive of the drive mechanism 6, the molding head 702 can accurately mate with the molding mold 2. At this time, molten plastic can be accurately injected into the molding tank 201 through the injection port 202. The molten plastic material will be molded inside the molding tank 201. The coolant inside the cooling frame 3 can cool the plastic material inside the molding mold 2. At the same time, the used coolant will be transported to the cooling frame 301. Then, the drive mechanism 6 drives the molding head 702. 02 is removed from the inside of the molding mold 2, and then the power gear 401 rotates, driving the meshing rack 402 to move linearly, thereby pushing the top plate 403 to move inside the molding mold 2, ejecting the molded plastic part from the mold. At the same time, the power of the power gear 401 is transmitted to the drive shaft 502 through the first drive belt 501, and the drive shaft 502 then transmits the power to the rotating shaft 302 through the second drive belt 503. The rotation of the rotating shaft 302 can cause the heat of the coolant inside the cooling frame 301 to dissipate. The cooled coolant will be transported back to the cooling frame 3 for use by the power pump 303.

[0034] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
