Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a blow molding mold for a water bucket. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to shape thermoplastic or thermosetting plastics into various shapes using plastic molds. During operation, the injection molding machine heats the plastic, applies high pressure to the molten plastic, and injects it into the mold to form the desired shape. During operation, the plastic extruded from the injection molding machine's extrusion head needs to be fitted onto a blowpipe. This is because in blow molding, the plastic needs to be extruded first to form a preform (equivalent to the barrel preform in this application), and then compressed air is injected into the preform through the blowpipe (equivalent to the blowpipe in this application) to expand it and fit it into the mold cavity, ultimately forming the desired plastic product.

[0003] The extrusion heads are located above the mold, while the blowpipe is located below. When the extrusion heads extrude the preform, because the preform is soft, it stretches too much during descent, causing the bottom of the preform to stick together. At this point, it is necessary to manually open the bottom opening of the preform before fitting it onto the blowpipe; otherwise, the bottom of the preform cannot be fitted onto the blowpipe, making the operation cumbersome. To address this, we propose a water bucket blow molding mold. Utility Model Content

[0004] This utility model provides a water bucket blow molding mold, which has the advantages of preventing the bottom of the bucket blank from deforming and being able to be fitted onto the blow molding rod in one go, thus solving the problems mentioned in the background art.

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

[0023] Reference Figures 1 to 7 This utility model provides a technical solution: a water bucket blow molding mold, comprising two mold bodies 1, each with a water bucket cavity 15 on its opposite surface, and a bucket opening 21 coaxially located at the bottom of each water bucket cavity 15. Connecting seats 2 are provided on both sides of the two mold bodies 1, each with a hole. In actual installation, the connecting seats 2 are mounted on an injection molding machine, allowing the two mold bodies 1 to open and close synchronously under the drive of the injection molding machine.

[0024] In reality, when the two mold bodies 1 are combined, i.e., the mold is closed, the openings 21 on both sides and the bucket cavity 15 are closed together, and the closed openings 21 and the bucket cavity 15 are consistent with the shape of the bucket to be produced. Figure 5 As shown, mold body 1 is always symmetrical about extruder head 19, that is, extruder head 19 is located directly above the two mold bodies, and blow rod 20 is coaxial with extruder head 19 and located below the mold. When the two mold bodies 1 are closed, the bucket cavity 15, bucket opening 21, blow rod 20 and extruder head 19 are coaxial. Figure 4 As shown, when the two mold bodies 1 are closed, the blow molding rod 20 extends into the barrel opening 21 under the drive of the blow molding machine to blow the barrel blank.

[0025] like Figure 1 and Figure 2As shown, this application also includes a strip seat 5, which is disposed on the side of one of the mold bodies 1. Specifically, the strip seat 5 is fastened to the side of the mold body 1 by bolts. It should be emphasized that both ends of the strip seat 5 must extend outside the mold body 1, and the strip seat 5 is vertically downward.

[0026] A lifting mechanism is provided on the strip base 5, and the lifting mechanism is located on the side of the strip base 5 away from the mold body 1. For example... Figure 1 , Figure 2 and Figure 3 As shown, the lifting mechanism includes mounting seats 4 respectively installed at both ends of the strip seat 5. A guide shaft 6 and a lead screw 7 are provided between the two mounting seats 4. There is at least one guide shaft 6, because the more guide shafts 6 there are, the better the support. There is only one lead screw 7. The lead screw 7 is parallel to the guide shaft 6. Both ends of the lead screw 7 are rotatably connected to the mounting seats 4, while both ends of the guide shaft 6 are fixed to the mounting seats 4.

[0027] A guide seat 12 is slidably sleeved on the guide shaft 6. A linear bearing can be installed inside the guide seat 12 to reduce friction. A nut 13 is threaded onto the lead screw 7 and is connected to the guide seat 12. The bottom of the lead screw 7 is connected to the drive motor 9. Figure 3 As shown, a motor seat 8 is provided at the bottom of the strip seat 5. The motor seat 8 is set on the mounting seat 4. The drive motor 9 is installed below the motor seat 8. When the drive motor 9 rotates, it can drive the lead screw 7 to rotate. The lead screw 7 drives the lead nut 13 and the guide seat 12 to move up and down reciprocally.

[0028] A second arm 17 is horizontally provided on one side of the lifting mechanism. The second arm 17 is located on one side of the mold body 1. A first arm 14 is vertically installed on the second arm 17. The first arm 14 extends horizontally toward the water bucket cavity 15. A support sleeve 3 is provided at the end of the first arm 14. The size of the support sleeve 3 is just enough to fit on the blow barrel rod 20.

[0029] The second arm 17 is detachable. Specifically, the guide seat 12 is connected to the end of the second arm 17 away from the first arm 14, and the end of the second arm 17 away from the first arm 14 is provided with a fixing seat 18. The fixing seat 18 is detachably connected to the guide seat 12, that is, the fixing seat 18 is fastened to the guide seat 12 by bolts. In this way, the second arm 17 and the first arm 14 can move up and down along the guide shaft 6.

[0030] like Figure 5 As shown, when the support sleeve 3 is at the top of the strip seat 5, the support sleeve 3 rises above the mold body 1 and is placed below the extrusion head 19. When the support sleeve 3 is at the bottom of the strip seat 5, the support sleeve 3 is below the mold body 1, and at this time the support sleeve 3 is fitted on the blow barrel rod 20.

[0031] Based on the above embodiments, the specific operation process is as follows: 1. As Figure 5As shown, the control drive motor 9 drives the support sleeve 3 to be located directly below the extrusion head 19. At this time, both mold bodies 1 must be in the open state at the same time.

[0032] 2. For example Figure 6 As shown, the barrel preform extruded by the extruder head 19 is controlled (e.g., Figure 6 (As indicated by the middle arrow A), the bottom of the barrel blank is placed on the support sleeve 3. Due to the support of the support sleeve 3, the bottom of the barrel blank is kept roughly round. At the same time, the support sleeve 3 is lowered by the drive motor 9, and the lowering speed is the same as the barrel blank extrusion speed.

[0033] 3. For example Figure 7 As shown, the support sleeve 3 guides the bottom of the barrel blank to fit onto the barrel opening 21. It should be noted that the support sleeve 3 is located below the mold body 1 at this time. At this time, the injection molding machine can be controlled to drive the two mold bodies 1 to close the mold, clamping the barrel blank between the two mold bodies 1. At this time, the blow rod 20 and the bottom of the barrel blank are both clamped inside the barrel opening 21. Then, the injection molding machine is controlled to blow air into the blow rod 20, thereby blowing the barrel blank into shape.

[0034] The above three steps 1-3 can form a water bucket. To produce multiple water buckets, the above steps can be repeated. The advantage of this process is that the bottom of the bucket blank extruded from the extruder 19 is always supported by the support sleeve 3, so that the bottom of the bucket blank does not deform and can be put on the blower rod 20 at once. This avoids the problem that the bottom of the bucket blank is deformed and needs to be manually sorted before it can be put on the blower rod 20.

[0035] Furthermore, such as Figure 3 As shown, both the second arm 17 and the first arm 14 are provided with adjustment grooves 16, and the second arm 17 is provided with an adjustment seat 22. The adjustment seat 22 is connected to the second arm 17 by fasteners.

[0036] The first arm 14 is placed on the adjusting seat 22, and the first arm 14 and the adjusting seat 22 are connected by fasteners. The fasteners are all placed in the adjusting groove 16. The fasteners are all bolts. When the bolts are loosened, the first arm 14 can extend and retract on the adjusting seat 22, and the adjusting seat 22 can be adjusted on the second arm 17. In this way, the relative position of the support sleeve 3 and the blow barrel rod 20 can be adjusted. After the position of the support sleeve 3 is adjusted, it can be fixed by bolts.

[0037] Furthermore, since the ambient temperature of the mold is high, the drive motor 9 is located inside the protective cover 10. The top of the protective cover 10 is detachably connected to the bottom of the motor base 8. Specifically, the top edge of the protective cover 10 is fastened to the bottom of the motor base 8 with bolts.

[0038] like Figure 1 and Figure 2As shown, the protective cover 10 has at least two pipe joints 11 on its side. One pipe joint 11 is connected to an air blowing device through a pipe. The air blowing device is an air pump that blows cold air into the protective cover 10, thereby allowing the hot air inside the protective cover 10 to be discharged from the other pipe joints 11.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
