Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a continuous processing injection mold. Background Technology

[0002] Injection molds are tools used for plastic injection molding. By injecting molten plastic into the mold cavity, and then cooling and solidifying it, plastic products with specific shapes and sizes are obtained. Using injection molds to mold plastics results in high precision, ensuring the dimensional and shape accuracy of the products, as well as good surface quality and uniform internal structure, which can meet the usage requirements of various products. However, most existing injection molds are one-time processing molds, which cannot be used for continuous production, affecting production efficiency. This paper proposes a continuous processing injection mold to solve the above problems. Utility Model Content

[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0004] To address the technical problems mentioned in the background section, some embodiments of this application provide a continuously processed injection mold, including a fixed mold, a support frame, a rotating shaft rotatably mounted on the support frame at one end, a load-bearing plate rotatably sleeved on the rotating shaft, two movable mold assemblies movably mounted on the load-bearing plate, a lifting device mounted on the support frame for controlling the relative movement of the two movable mold assemblies, and a driving device mounted on the support plate for driving the load-bearing plate to rotate; the driving device includes two movably symmetrically mounted support rods on the load-bearing plate, two limiting blocks respectively fixed on the two support rods, two limiting grooves mounted on the support frame and cooperating with the two limiting blocks, and a handle fixed on the two support rods; the handle is movably mounted on the support frame.

[0005] Specifically, one of the moving mold assemblies includes two telescopic rods fixed at one end to a load-bearing plate, a fixed plate fixed at the other end of the two telescopic rods, a molding box fixed on the fixed plate, and a top rod that is movably disposed through the fixed plate and the molding box.

[0006] Specifically, the lifting device includes two lifting components that drive two moving mold groups to move relative to each other, two gears fixed on the rotating shaft, two locking blocks fixed on the rotating shaft, two slots on the handle that engage with the two locking blocks respectively, and a motor fixed on the handle for driving the rotating shaft to rotate.

[0007] Specifically, the lifting assembly includes two racks fixedly mounted on a fixed plate and respectively meshing with two gears, a sliding groove on the two racks, and two sliders fixedly mounted on a load-bearing plate.

[0008] Specifically, the end of the rotating shaft connected to the motor is provided with a cross-shaped locking block; a connecting rod is fixedly provided on the motor; and a cross-shaped locking groove is provided on the connecting rod to cooperate with the cross-shaped locking block.

[0009] Specifically, the push rod is threaded into the fixing plate.

[0010] Specifically, one end of the push rod is tightly fitted with the molding box.

[0011] The beneficial effects of this utility model are:

[0012] The fixed mold is connected to the injection nozzle of the injection molding machine. During injection, the two limit blocks on the support rod engage with the two limit slots on the support frame to prevent the load-bearing plate from rotating. After injection, the mold cools for a period of time. The lifting device is then controlled to lower the moving mold assembly and separate it from the fixed mold. The handle is moved away from the load-bearing plate to disengage the two limit blocks from the two limit slots. The handle is then rotated to rotate the load-bearing plate 180°, so that the un-injected moving mold assembly faces upward. The handle is then moved in the opposite direction, and the lifting device controls the un-injected moving mold to rise and contact the fixed mold for injection. The already-injected moving mold assembly faces downward, and after cooling and molding, it can be demolded. Using an injection mold with the above structure, the two moving mold assemblies are used alternately, allowing for continuous processing while simultaneously injecting, cooling, and demolding, saving time and improving processing efficiency.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1-4 As shown, the continuous injection mold of this utility model includes a fixed mold 1, a support frame 2, a rotating shaft 3 rotatably mounted on the support frame 2 at one end, a load-bearing plate 4 rotatably sleeved on the rotating shaft 3, two movable mold assemblies 5 movably mounted on the load-bearing plate 4, a lifting device 6 mounted on the support frame 2 for controlling the relative movement of the two movable mold assemblies 5, and a driving device 7 mounted on the support plate for driving the load-bearing plate 4 to rotate; the driving device 7 includes two movably symmetrically mounted support rods 71 ​​on the load-bearing plate 4, two limiting blocks 72 respectively fixed on the two support rods 71, two limiting grooves 73 mounted on the support frame 2 and cooperating with the two limiting blocks 72, and a handle 74 fixed on the two support rods 71; the handle 74 is movably mounted on the support frame 2.

[0026] Specifically, one of the moving mold groups 5 includes two telescopic rods 51 fixed at one end to the load-bearing plate 4, a fixing plate 52 fixed at the other end of the two telescopic rods 51, a molding box 53 fixed on the fixing plate 52, and a top rod 54 that is movably disposed through the fixing plate 52 and the molding box 53.

[0027] Specifically, the lifting device 6 includes two lifting components 61 that drive the two moving mold groups 5 to move relative to each other, two gears 62 fixed on the rotating shaft 3, two locking blocks 63 fixed on the rotating shaft 3, two slots 64 on the handle 74 that engage with the two locking blocks 63 respectively, and a motor 65 fixed on the handle 74 for driving the rotating shaft 3 to rotate.

[0028] Specifically, the lifting assembly 61 includes two racks 611 fixed on the fixed plate 52 and respectively meshing with two gears 62, a slide groove 612 provided on the two racks 611, and two sliders 613 fixed on the load-bearing plate 4.

[0029] Specifically, the end of the rotating shaft 3 connected to the motor 65 is provided with a cross-shaped locking block 31; a connecting rod 32 is fixedly provided on the motor 65; and a cross-shaped locking groove 33 is provided on the connecting rod 32 to cooperate with the cross-shaped locking block 31.

[0030] The fixed mold 1 is connected to the injection nozzle of the injection molding machine. In the initial state, the two limit blocks 72 on the two support rods 71 ​​are engaged with the two limit grooves 73 on the support frame 2 to prevent the load-bearing plate 4 from rotating. The connecting rod 32 on the motor 65 is engaged with the cross block on the rotating shaft 3. The two blocks 63 on the rotating shaft 3 are disengaged from the two grooves 64 on the handle 74 to prevent the handle 74 from rotating with the rotating shaft 3. Before injection molding into one of the molding boxes 53, start motor 65. Motor 65 drives rotating shaft 3 to rotate, two gears 62 rotate, and two moving mold groups 5 move in opposite directions until the injection height is reached. Then, turn off motor 65 and start injection molding. After injection molding is completed, allow it to cool for a period of time, then turn motor 65 back on to reverse it. The two moving mold groups 5 move towards each other. Then, turn off motor 65 again and move handle 74 away from the load-bearing plate 4. At this time, the two limiting blocks 72 on the two support rods 71 ​​disengage from the two limiting grooves 73 on the support frame 2, the connecting rod 32 disengages from rotating shaft 3, and the two locking blocks 63 on rotating shaft 3 disengage from the two locking blocks 64 on handle 74. When the slot 64 engages, rotating the handle 74 180 degrees causes the two support rods 71 ​​to rotate, which in turn rotates the load-bearing plate 4. Simultaneously, the handle 74 also rotates the rotating shaft 3. The load-bearing plate 4 then rotates the two moving mold assemblies 5 180 degrees. Since the load-bearing plate 4 rotates the two racks 611, and the rotating shaft 3 rotates the two gears 62, there is no relative rotation between the two gears 62 and the two racks 611. After the 180-degree rotation, the molded moving mold assembly 5 faces downwards, allowing the plastic product inside to continue cooling and then be demolded. The unmolded moving mold assembly 5 faces upwards. Moving the handle 74 in the opposite direction returns the entire injection mold to its initial state, allowing injection to begin again. Using an injection mold with this structure, the two moving mold assemblies 5 work alternately, enabling simultaneous injection, cooling, and demolding, achieving continuous processing, saving processing time, and improving production efficiency.

[0031] The lifting device 6 is set up so that the moving mold group 5 and the fixed mold 1 are separated. On the other hand, the space required for rotation is reduced after the two moving mold groups 5 are close to each other, thus saving space. When demolding, the bottom of the force support frame 2 of the injection-molded moving mold group 5 is closer, so the plastic product receives less reaction force from the support frame 2 after falling, thus preventing defects or even damage to the plastic product after falling.

[0032] Specifically, the push rod 54 is threadedly engaged with the fixing plate 52.

[0033] Specifically, one end of the top rod 54 is tightly fitted with the molding box 53.

[0034] One end of the ejector pin 54 is tightly fitted with the molding box 53 to prevent the injection molding liquid from flowing out from the gap between the ejector pin 54 and the molding box 53. When demolding, rotate the ejector pin 54 to eject the completely cooled plastic product from the molding box 53. After demolding, rotate the ejector pin 54 again to align one end of the ejector pin 54 with the inner bottom surface of the molding box 53, and then start the next injection molding process.

[0035] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of this disclosure is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept.
