Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically a high-speed injection mold for packaging barrels. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding of complex products. In the production of packaging barrels, injection molds are required for manufacturing.

[0003] Chinese Patent Publication No. CN221819422U discloses an improved high-speed injection mold for packaging barrels, including an upper platen and a lower platen. A fixed template is provided under the upper platen, and mold feet are provided on the lower platen. An ejector device for the packaging barrel is provided on the lower platen between the mold feet. A movable template is provided on the mold feet, and a movable mold insert is provided on the movable template. A top insert is provided on the movable mold insert. An inclined ejector slider is provided on the movable template surrounding the movable mold insert. A water channel insert is provided at the bottom of the movable mold insert, and a lower water inlet and a lower water outlet are formed in the water channel insert. A lower water inlet and a lower water outlet are formed in the movable mold insert. The water channel has a lower annular water channel in the top insert, and the lower water inlet is connected to the lower water inlet, lower annular water channel, lower water outlet, and lower water outlet. The upper cover plate has an upper water inlet and an upper water outlet. A fixed mold insert is set under the upper cover plate, and the fixed mold insert has an upper annular water channel. The upper water inlet is connected to the upper annular water channel and the upper water outlet. However, the above patent only has upper and lower ejector plates when removing the mold. When ejecting, it is necessary to use additional tools or manually to lift it up, which makes demolding time-consuming and labor-intensive and reduces efficiency. Therefore, we propose a high-speed injection mold for packaging barrels. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed injection mold for packaging barrels, so as to solve the problem in the prior art that when ejecting, it is necessary to use additional tools or manual labor to lift the barrel, which makes demolding time-consuming, labor-intensive and reduces efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-speed injection mold for packaging barrels, including a base plate, a support plate symmetrically fixed to the top of the base plate, a lower mold fixed to the top of the support plate, an upper mold connected to the top of the lower mold, an ejection mechanism connected to the top of the base plate, and locking mechanisms connected to both sides of the support plate.

[0006] The ejection mechanism includes fixed plates symmetrically fixed to the top of the base plate, a rotating shaft passing through the opposite sides of the two fixed plates, turntables fixed at both ends of the rotating shaft, deflection rods symmetrically fixed to the outer side of the rotating shaft, extrusion rollers rotating inside the deflection rods, an ejection rod sliding through the bottom center of the lower die, and a force-bearing plate fixed to the bottom end of the ejection rod.

[0007] Preferably, the ejection mechanism further includes limit rods fixed at the four bottom corners of the lower mold, and a return spring is sleeved on the outer side of the limit rods.

[0008] Preferably, the upper and lower ends of the reset spring are fixedly connected to the bottom of the lower mold and the top of the force plate, respectively, so as to facilitate the reset of the force plate.

[0009] Preferably, positioning rods are fixed at the top four corners of the lower mold, and positioning holes are provided at the bottom four corners of the upper mold to allow the upper and lower molds to fit together. An injection port is provided through the top center of the upper mold, and a cooling cavity is provided inside the upper mold. Connecting pipes are symmetrically fixed at the top of the upper mold to facilitate cooling and speed up the molding process.

[0010] Preferably, the locking mechanism includes ear plates symmetrically fixed to both sides of the upper mold. A slot is provided in the middle of one side of each ear plate, and insertion holes are symmetrically provided through the top of each ear plate. Connecting seats are fixed to both sides of the support plate. A rotating block is rotatably mounted inside each connecting seat. A sleeve is fixed to one side of each rotating block. A connecting rod slides through the middle of the top of the sleeve. A circular plate is fixed to the bottom of the connecting rod. A connecting spring is fixed to the middle of the bottom of the circular plate. A pressure plate is fixed to the top of the connecting rod. Inserted rods are symmetrically fixed to the bottom of the pressure plate. A pull handle is fixed to the top of the pressure plate.

[0011] Preferably, the circular plate is slidably connected to the inside of the sleeve, and the outer side wall of the circular plate is in contact with the inner side wall of the sleeve, so that the circular plate can move stably.

[0012] Preferably, the bottom end of the connecting spring is fixed to the bottom of the inner cavity of the sleeve to facilitate tightening the circular plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, by using the ejection mechanism, the rotating turntable drives the rotating shaft to rotate, causing the deflection rod to deflect, which in turn drives the extrusion roller to deflect, so that the extrusion roller contacts the force plate and extrudes the force plate. This causes the force plate to slide outside the limit rod, extruding the return spring and moving the ejection rod to push the formed packaging barrel down, which facilitates demolding, making demolding more time-saving and labor-saving, and improving demolding efficiency.

[0015] 2. In this application, by using a locking mechanism, pulling the handle moves the pressure plate, which in turn moves the connecting rod and the circular plate, stretching the connecting spring. Then, rotating the sleeve positions the connecting rod inside the slot, aligning the insertion hole with the rod. Loosening the handle causes the circular plate to reset via the connecting spring, which in turn moves the pressure plate back to its original position. This causes the pressure plate to press against the ear plate, while simultaneously embedding the rod into the insertion hole. This causes the upper mold to press against the lower mold, locking the mold and eliminating the need for a separate device to lock it. This improves the convenience of the device, and locking the mold also enhances the quality of the product molding. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a technical solution for a high-speed injection mold for packaging barrels, including a base plate 100, a support plate 200 symmetrically fixed on the top of the base plate 100, a lower mold 300 fixed on the top of the support plate 200, an upper mold 400 connected to the top of the lower mold 300, an ejection mechanism 500 connected to the top of the base plate 100, and locking mechanisms 600 connected to both sides of the support plate 200.

[0024] Please see Figure 2 and Figure 3 The ejection mechanism 500 includes fixed plates 510 symmetrically fixed to the top of the base plate 100. A rotating shaft 520 rotates through the opposite sides of the two fixed plates 510. Turntables 530 are fixed to both ends of the rotating shaft 520. Deflecting rods 540 are symmetrically fixed to the outer side of the rotating shaft 520. A pressing wheel 550 rotates inside the deflecting rod 540. An ejection rod 590 slides through the center of the bottom of the lower die 300. A force plate 570 is fixed to the bottom end of the ejection rod 590. The ejection mechanism 500 also includes limit rods 560 fixed at the four corners of the bottom of the lower die 300. Return springs 580 are sleeved on the outer side of the limit rods 560. The upper and lower ends of the return springs 580 are fixedly connected to the bottom of the lower die 300 and the top of the force plate 570, respectively. The four corners of the top of the lower die 300 are fixed... The upper mold 400 has a positioning rod 310, positioning holes 410 at the four corners of its bottom, an injection port 420 through the center of its top, a cooling cavity 430 inside, and connecting pipes 440 symmetrically fixed to its top. The ejection mechanism 500 rotates the turntable 530, causing the rotating shaft 520 to rotate, which in turn deflects the deflection rod 540, causing the extrusion roller 550 to deflect. This causes the extrusion roller 550 to contact the force plate 570, extruding it and causing the force plate 570 to slide outside the limiting rod 560, thus extruding the return spring 580. Simultaneously, the ejection rod 590 moves, pushing the formed packaging barrel down for easier demolding, saving time and effort and improving demolding efficiency.

[0025] Please see Figure 4 and Figure 5The locking mechanism 600 includes ear plates 610 symmetrically fixed to both sides of the upper mold 400. A slot 611 is provided in the middle of one side of each ear plate 610, and insertion holes 620 are symmetrically provided through the top of each ear plate 610. Connecting seats 630 are fixed to both sides of the support plate 200. A rotating block 640 rotatably rotates inside the connecting seat 630. A sleeve 650 is fixed to one side of the rotating block 640. A connecting rod 660 slides through the middle of the top of the sleeve 650. A circular plate 670 is fixed to the bottom end of the connecting rod 660. A connecting spring 671 is fixed to the middle of the bottom of the circular plate 670. A pressure plate 680 is fixed to the top of the connecting rod 660. Inserted rods 681 are symmetrically fixed to the bottom of the pressure plate 680, and a pull handle 690 is fixed to the top of the pressure plate 680. The circular plate 670 is slidably connected to the inside of the sleeve 650, and the outer wall of the circular plate 670 is flush with the sleeve 650. The inner wall of sleeve 60 is fitted; the bottom end of connecting spring 671 is fixed to the bottom of the inner cavity of sleeve 650; by using locking mechanism 600, pulling handle 690 moves pressure plate 680, causing connecting rod 660 to move, causing round plate 670 to move, stretching connecting spring 671, then rotating sleeve 650 so that connecting rod 660 is inside slot 611, so that insertion hole 620 is aligned with insertion rod 681. Loosening handle 690 causes round plate 670 to reset through connecting spring 671, causing connecting rod 660 to reset pressure plate 680, so that pressure plate 680 presses ear plate 610, and at the same time, insertion rod 681 is embedded in insertion hole 620, so that upper mold 400 presses lower mold 300, locking mold, avoiding the need for a separate device to lock mold, improving the convenience of the device, and locking mold improves product molding quality.

[0026] In use, the upper mold 400 and lower mold 300 are assembled, positioning the positioning rod 310 in the positioning hole 410. Then, the handle 690 is pulled, moving the pressure plate 680, which in turn moves the connecting rod 660, causing the circular plate 670 to move and stretching the connecting spring 671. Next, the sleeve 650 is rotated, positioning the connecting rod 660 inside the slot 611, aligning the insertion hole 620 with the insertion rod 681. The handle 690 is then released, causing the circular plate 670 to reset via the connecting spring 671, which in turn causes the connecting rod 660 to reset the pressure plate 680, pressing the pressure plate 680 against the ear plate 610. Simultaneously, the insertion rod 681 is inserted into the insertion hole 620, thus pressing the upper mold 400. The lower mold 300 is locked, and raw material is injected into the injection port 420 for injection molding. Then, coolant is injected into the connecting pipe 440 for cooling. After cooling, the handle 690 is pulled to move the insert rod 681 out of the insertion hole 620, deflecting the sleeve 650 to release the fixation. The upper mold 400 is then removed, and the turntable 530 is rotated to drive the rotating shaft 520 to rotate, causing the deflecting rod 540 to deflect and drive the extrusion roller 550 to deflect, so that the extrusion roller 550 contacts the force plate 570 and extrudes the force plate 570. This causes the force plate 570 to slide outside the limit rod 560, extruding the return spring 580 and simultaneously moving the ejector rod 590 to push down the formed packaging barrel.
