However, the water circulation device and the pipeline connecting the water distribution block arranged in this way have the following disadvantages in use: the pipeline is located on the turntable, occupying the area of the turntable and posing a shearing risk to the operator when the pipeline rotates with the turntable.

[0033] The present utility model proposes a vertical injection molding machine.

[0034] Please refer to Figures 1 to 4, in an embodiment of the present utility model, the injection molding machine main body 100 includes a lower template 110, a turntable assembly 120, and a water distribution assembly 130; the turntable assembly 120 is rotatably arranged on the lower template 110, the turntable assembly 120 has a first surface 121 and a second surface 122 arranged opposite to each other, and the second surface 122 is used for installing a lower mold; the turntable assembly 120 has a through hole 123 penetrating along its axis direction; the water distribution assembly 130 is arranged on the turntable assembly 120, the water distribution assembly 130 includes a water distribution seat 131, a first pipe body 132, and a second pipe body 133, the first pipe body 132, the water distribution seat 131, and the second pipe body 133 are sequentially communicated, the first pipe body 132 has a water inlet 1321, the second pipe body 133 has a water outlet 1331, and a part of the water distribution assembly 130 passes through the through hole 123, so that the water inlet 1321 is located on one side of the first surface 121 away from the second surface 122, and the water outlet 1331 is located on one side of the second surface 122 away from the first surface 121, the water inlet 1321 is used for communicating with an external water source, and the water outlet 1331 is used for communicating with a lower mold;

[0035] The technical solution of the utility model is to install the lower template 110 on the frame of the injection molding machine body 100, and rotatably set the turntable assembly 120 on the lower template 110, so that the vertical injection molding machine can perform loading operations while injecting. When the injection molding machine body 100 produces plastic products, it is usually necessary to cool the injection mold to cool the plastic in the injection mold. The injection mold generally includes an upper mold and a lower mold. The upper mold and the lower mold are closed to form an injection cavity. In this embodiment, the lower mold is detachably arranged on the turntable assembly 120. Since multiple lower molds are arranged on the turntable assembly 120, in order to realize multiple lower molds, In order to cool the molds, a water-dividing assembly 130 is provided on the turntable assembly 120. The water-dividing assembly 130 can cool multiple lower molds at the same time. In order to avoid the pipeline for connecting the water-dividing assembly 130 and the external water source being located on the second surface 122 of the turntable assembly 120 for installing the injection molding module, in the present embodiment, the water-dividing assembly 130 is also provided on the turntable assembly 120, wherein the water-dividing assembly 130 includes a water-dividing seat 131, a first tube body 132 and a second tube body 133. The first tube body 132, the water-dividing seat 131 and the second tube body 133 are connected in sequence, and a water inlet 1321 is provided at one end of the first tube body 132. The water inlet 1321 The first tube body 132 is used to communicate with an external water source, and the other end is used to communicate with the water separation seat 131. One end of the second tube body 133 is used to communicate with the water separation seat 131, and the other end is provided with a water outlet 1331, and the water outlet 1331 is used to communicate with the cooling flow path in the lower mold. In this embodiment, a through hole 123 is provided through the turntable assembly 120, and the through hole 123 is used for a part of the water separation assembly 130 to pass through, so that the water inlet 1321 of the first tube body 132 is located on the side of the first surface 121 of the turntable assembly 120 away from the second surface 122, and the water outlet 1331 of the second tube body 133 is located on the second surface 122 of the turntable assembly 120 away from On one side of the first surface 121, an external water source is connected to the first tube body 132 located on the first surface 121 of the turntable assembly 120 through such an arrangement, that is, the pipeline used to connect the external water source and the water distribution assembly 130 is located below the first surface 121 of the turntable assembly 120. Such an arrangement allows the pipeline to be arranged in a hidden manner and reduces the occupancy of the second surface 122 of the turntable assembly 120, making the second surface 122 of the turntable assembly 120 for installing the injection mold clearer. Secondly, there are no protruding pipelines on the second surface 122 of the turntable assembly 120, which can avoid the risk of shearing to the operator when the turntable assembly 120 rotates.

[0036] It can be understood that common injection molds include an upper mold and a lower mold. When the injection mold is in the injection molding state, the upper mold and the lower mold are in the closed mold state, so that a closed mold cavity is formed inside the injection mold for the plasticizing injection device to inject molten masterbatch; when the injection mold is in the material taking state, the upper mold and the lower mold are in the open mold state, so that the operator can take out the injection molded product inside the injection mold. In this embodiment, the upper mold is detachably installed on one side of the upper template 143 facing the lower template 110, and the lower mold is detachably installed on one side of the turntable assembly 120 facing the upper template 143. Since the injection mold belongs to the prior art, the specific structure thereof will not be described in detail in this application.

[0037] Among them, the plasticizing injection device is a device that injects the plastic in the molten state (i.e., the viscous flow state) that has been plasticized into the mold cavity of the closed injection mold by means of the thrust of a screw (or a plunger). Since the plasticizing injection device belongs to the prior art, the specific structure thereof will not be described in detail in this application.

[0038] In one embodiment, as Figure 2 shown, the number of the second pipe bodies 133 is multiple; the water distribution seat 131 includes a water distribution pipeline, and the water distribution pipeline includes a confluence port and two diversion ports. The confluence port is used to communicate with the first pipe body 132, and the two diversion ports are respectively used to communicate with the multiple second pipe bodies 133 in one-to-one correspondence. In order to enable the second pipe body 133 to cool multiple lower molds at the same time, in this embodiment, a water distribution pipeline is provided inside the water distribution seat 131. The water distribution pipeline includes a confluence port and two diversion ports. The two diversion ports are respectively used to communicate with the multiple second pipe bodies 133, so that after the external water source flows through the first pipe body 132 to the confluence port, it then flows through the diversion ports in the water distribution pipeline to the multiple second pipe bodies 133 to cool multiple injection molds; in this embodiment, in order to centrally collect and process the liquid after cooling is used, a recovery pipeline is further provided on the water distribution block. The specific structure of the recovery pipeline can be set with reference to the water distribution pipeline, and will not be described in detail here; for the convenience of wiring, in this embodiment, a wiring pipeline for wiring can also be provided on the water distribution seat 131. Of course, in this embodiment, the water distribution pipeline, the recovery pipeline and the wiring pipeline are independently provided.

[0039] In one embodiment, the turntable assembly 120 includes a driving motor and a turntable. The turntable has an initial position and a preset position which are oppositely arranged. The driving motor is used to drive the turntable to rotate reciprocally by 180 degrees, so as to swap the initial position and the preset position. In this embodiment, the turntable assembly 120 includes a driving motor and a turntable. Among them, the driving motor is mainly used to drive the turntable to rotate. The turntable has an initial position and a preset position which are oppositely arranged. An operator can place the injection mold at the initial position or the preset position of the turntable or between the initial position and the preset position. The driving motor can drive the turntable to rotate reciprocally by 180 degrees, that is, the driving motor drives the turntable to rotate from the initial position to the preset position, and then drives the turntable to rotate from the preset position to the initial position along the direction opposite to the above rotation direction, so as to swap the initial position and the preset position. In this way, the position of the injection mold arranged on the turntable can be swapped, so that the lower mold rotates from the loading station to the injection station, or rotates from the injection station to the loading station. To make the turntable more stable during rotation, in this embodiment, as Figure 1 shown, a plurality of guiding members are arranged on the lower template 110 along the outer periphery of the turntable, and the plurality of guiding members are slidably connected to the outer peripheral side of the turntable.

[0040] In this embodiment, the vertical injection molding machine further includes a mold clamping mechanism 140. The mold clamping mechanism 140 includes guide columns 142 passing through the lower template 110 and the turntable assembly 120, lifting plates 145 and an upper template 143 located at both ends of the guide columns 142, and a mold clamping oil cylinder 141 and a moving mold oil cylinder 144 located between the lifting plate 145 and the lower template 110. Among them, the lifting plate 145 is located below the lower template 110, the upper template 143 is located above the lower template 110, and both the mold clamping oil cylinder 141 and the moving mold oil cylinder 144 are detachably installed on the side of the lower template 110 away from the turntable assembly 120 and are located between the lower template 110 and the lifting plate 145. The moving mold oil cylinder 144 is fixedly connected to the lifting plate 145, and the lifting plate 145 is indirectly fixedly connected to the upper template 143 through the guide columns 142. Upper molds and lower molds are respectively detachably provided on the opposite surfaces of the upper template 143 and the lower template 110. Therefore, when the molds are closed, the moving mold oil cylinder 144 will extend downward to push the lifting plate 145 to move away from the lower template 110. Since the lifting plate 145, the guide columns 142 and the upper template 143 are fixedly connected, when the lifting plate 145 moves away from the lower template 110, it will synchronously drive the guide columns 142 and the upper template 143 to move. Because the upper template 143 is located above the lower template 110, the upper template 143 will move toward the lower template 110 at this time. When the upper mold on the upper template 143 is closed with the lower mold on the lower template 110, the mold clamping oil cylinder 141 injects hydraulic oil to lock the mold under high pressure, and then the corresponding injection molding steps are completed. On the contrary, when the molds are opened, the moving mold oil cylinder 144 drives the lifting plate 145 to move toward the lower template 110. At this time, the upper template 143 moves away from the lower template 110, and the upper mold and the lower mold are separated. At this time, the demolding operation can be performed.

[0041] In one embodiment, as Figure 4 shown, the lower template 110 is provided with an avoidance groove 111 for the first pipe body 132 of the water distribution assembly 130 to rotate with the turntable assembly 120. To prevent the water supply pipe and / or the drainage pipe and / or the conduction line communicating with the water distribution assembly 130 below the turntable assembly 120 from rubbing against the lower template 110 when the turntable assembly 120 reciprocally rotates between 0° and 180°, resulting in wear and damage to the water supply pipe and / or the drainage pipe and / or the conduction line, in this embodiment, an avoidance groove 111 is opened on the lower template 110. The provision of this avoidance groove 111 can prevent the water supply pipe and / or the drainage pipe and / or the conduction line from rubbing against the lower template 110 when rotating with the turntable assembly 120.

[0042] In one embodiment, the circumferential side of the lower template 110 is chamfered; and / or on the side of the lower template 110 away from the turntable assembly 120, reinforcing ribs 112 are provided. The reinforcing ribs 112 and the avoidance grooves 111 extend along the radial direction of the turntable assembly 120 to both ends of the lower template 110, and the reinforcing ribs 112 are adjacent to the avoidance grooves 111. In this embodiment, since the avoidance grooves 111 are provided on the lower template 110, in order to improve the structural strength of the lower template 110, the circumferential side of the lower template 110 is chamfered. Such a setting can effectively disperse the stress concentration points. In structural mechanics, sharp corners are often places where stress concentration occurs, which easily causes cracks or fractures. By chamfering, the stress level in these areas can be significantly reduced, and the overall crack resistance and durability of the lower template 110 can be improved.

[0043] In another embodiment, reinforcing ribs 112 are also provided on the side of the lower template 110 away from the turntable assembly 120. The setting of the reinforcing ribs 112 can effectively improve the overall rigidity of the lower template 110. The addition of the reinforcing ribs 112 can significantly improve the rigidity of the lower template 110, that is, the ability of the lower template 110 to resist deformation. Of course, in this embodiment, the circumferential side of the lower template 110 can also be chamfered as in the above embodiment, so as to achieve a better effect on the structural stability of the lower template 110.

[0044] In one embodiment, the avoidance groove 111 has a first position 1111 and a second position 1112. When the turntable is in the initial position, the water distribution assembly 130 is located at the first position 1111 of the avoidance groove 111. When the turntable assembly 120 is in the preset position, the water distribution assembly 130 is located at the second position 1112 of the avoidance groove 111. In this embodiment, the avoidance groove 111 is provided with a first position 1111 and a second position 1112. In order to enable the first pipe body 132 in the water distribution assembly 130 to rotate reciprocally as in the above embodiment with the turntable assembly 120 without entanglement, the avoidance groove 111 is provided. Since the rotation angle of the turntable assembly 120 is 180 degrees, therefore, in this embodiment, the opening angle of the avoidance groove 111 should be greater than or equal to 180 degrees, that is, the opening angle from the first position 1111 to the second position 1112 should be greater than or equal to 180 degrees. Or when the turntable is in the initial position, the water distribution assembly 130 can be arranged at the second position 1112 of the avoidance groove 111, and when the turntable is in the preset position, the water distribution assembly 130 can be arranged at the first position 1111 of the avoidance groove 111.

[0045] In one embodiment, as Figure 1As shown, the vertical injection molding machine further includes an ejection mechanism 150. The ejection mechanism 150 is disposed on a side of the lower template 110 away from the turntable assembly 120. The ejection mechanism 150 is used to eject the injection molded product in the lower mold located above the turntable assembly 120. To facilitate the removal of the injection molded product from the inside of the injection mold by the vertical injection molding machine, in this embodiment, an ejection mechanism 150 is further provided. The ejection mechanism 150 is disposed on a side of the lower template 110 away from the turntable assembly 120, and the lower template 110 is provided with a through hole for the ejector of the ejection mechanism 150 to pass through. The turntable assembly 120 is also provided with a through hole for the ejector of the ejection mechanism 150 to pass through. When two sets of injection molds are provided on the turntable assembly 120, two sets of through holes are provided. When the injection mold on the turntable assembly 120 is injection molded and the internal product needs to be removed, the turntable assembly 120 rotates to a preset position, that is, the position where the through hole on the turntable assembly 120 corresponds to the through hole on the lower template 110. At this time, the ejection mechanism 150 drives the ejector to pass through the two through holes to eject the product in the injection mold, so that the operator can more conveniently remove the product from the injection mold.

[0046] In this embodiment, the through hole 123 is located between the turntable assembly 120 from its axis to the ejection mechanism 150 and is disposed close to the first position 1111 or the second position 1112, or may be disposed between the first position 1111 and the second position 1112. Similar to the above embodiment, to prevent the water supply pipeline and / or the drainage pipeline and / or the conduction line from rubbing against the transmission member and the ejection mechanism 150, in this embodiment, the through hole 123 formed on the turntable assembly 120 is preferably formed between the axis of the turntable assembly 120 and the ejection mechanism 150 and is disposed close to the first position 1111 or the second position 1112, or may be between the first position 1111 and the second position 1112. The through hole 123 arranged in this way can prevent the water supply pipeline and / or the drainage pipeline and / or the conduction line from rubbing against the transmission member and / or the ejection mechanism 150.

[0047] In one embodiment, as Figure 1As shown, the vertical injection molding machine further includes a locking mechanism 160. The locking mechanism 160 is disposed on the side of the lower template 110 away from the turntable. The locking mechanism 160 can abut against the turntable when the turntable rotates to the initial position or a preset position to limit the rotation of the turntable. In this embodiment, the vertical injection molding machine further includes a locking mechanism 160. The locking mechanism 160 is disposed on the side of the lower template 110 away from the turntable assembly 120, just like the ejecting mechanism 150 in the above embodiment. The locking mechanism 160 can abut against the turntable when the turntable is in the initial position, that is, the initial position. At this time, it is convenient for the operator to take out the finished product in one of the lower molds on the turntable and perform injection molding operations on another lower mold. The locking mechanism 160 can also abut against the turntable again after the turntable assembly 180 rotates by °. At this time, another injection mold that was previously in the injection molding process rotates to the position for taking out the finished product, and one injection mold flips to the position of the previous another injection mold for injection molding operations. Through such a setting, the safety of the operator when performing corresponding operations on the lower molds on the turntable can be improved.

[0048] In one embodiment, as Figure 1 shown, a plurality of mounting holes 124 are formed in the turntable assembly 120. The mounting holes 124 are used for mounting the lower mold. For the convenience of disassembling and installing the lower mold, in this embodiment, a plurality of mounting holes 124 are formed in the turntable of the turntable assembly 120. The mounting holes 124 can improve the installation efficiency when the operator installs the lower mold on the turntable.

[0049] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
