Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a pen water reservoir. Background Technology

[0002] Injection molds are tools used to produce plastic products; they also give plastic products their complete structure and precise dimensions. Injection molding is a processing method used for the mass production of certain complex-shaped parts. Specifically, it involves injecting molten material under high pressure into a mold cavity consisting of a moving mold and a stationary mold. The mold is first cooled by coolant in cooling channels located around the mold cavity, which is then transferred to the material inside the mold cavity for cooling and solidification. After the material is cooled and solidified, the equipment drives the moving mold to separate it from the stationary mold, ultimately resulting in the injection-molded product.

[0003] Traditional injection molds, especially those designed for internal core-pulling, typically incorporate a side-mounted power mechanism for core-pulling and demolding before the main mold separates. However, this multi-power-source design based on core-pulling leads to two problems: firstly, it complicates the mold and its mating structure; secondly, it increases the time required for demolding during a single injection molding process, making it difficult to improve injection efficiency. Furthermore, this structural design is not ideal for the utilization and occupancy of space within the injection molding equipment, often requiring larger injection molding machines to produce the same number of molded parts. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide an injection mold for a pen water reservoir that can improve production efficiency and reduce equipment usage requirements.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pen reservoir injection mold, including a moving mold, a stationary mold, and a runner plate, wherein a core-pulling mechanism is provided between the moving mold and the stationary mold, a cavity plate is provided on the stationary mold, the core-pulling mechanism is positioned opposite the cavity plate, and the moving mold is also connected to a guide plate, wherein the guide plate is used for the core-pulling mechanism to pull the core relative to the cavity plate when the moving mold separates from the stationary mold.

[0006] As a further feature of the above solution, the core-pulling mechanism includes a movable plate and a core plate fixed to the movable plate, and a push plate with a slope that cooperates with the inclined surface of the movable plate on the outward side.

[0007] As a further feature of the above solution, the guide plate is fixedly connected to the moving mold and has a beveled part. The movable plate is also provided with a beveled opening, and the beveled part and the beveled opening are matched.

[0008] As a further feature of the above scheme, sliding plates are provided on both sides of the movable plate, and pressure plates are bolted to the sides of the flow channel plate opposite to the movable plate. The pressure plates form a groove on the flow channel plate, and the sliding plates move relative to the flow channel plate based on the sliding plates and the groove.

[0009] As a further feature of the above scheme, the flow channel plate is provided with an injection flow channel, and the moving mold is also provided with a manifold and a hot nozzle. One end of the hot nozzle abuts against the injection port of the manifold and the other end is connected to the injection flow channel.

[0010] As a further feature of the above scheme, the cavity plate includes a moving template and a stationary template that interlock to form a mold cavity. The mold cavity is also provided with a runner opening, which is opposite to the injection runner on the runner plate.

[0011] Beneficial effects: The injection mold of this utility model, by setting multiple inclined surface cooperation structures, pulls the moving force of the mold opening and closing action of the moving mold and the stationary mold to the core feeding direction of the mandrel, thereby integrating the multi-step work of the mold into the mold opening and closing, reducing the waiting time between each action, reducing the mold volume occupation, improving work efficiency, and improving space utilization, so that the mold can be used on smaller machines.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0019] like Figure 1-5 The illustrated pen reservoir injection mold includes a moving mold 1, a stationary mold 2, and a runner plate 3. A core-pulling mechanism 5 is also provided between the moving mold 1 and the stationary mold 2. A cavity plate 4 is provided on the stationary mold 2. The core-pulling mechanism 5 is positioned opposite the cavity plate 4. The moving mold 1 is also connected to a guide plate 53. The guide plate 53 is used by the core-pulling mechanism 5 to pull the core relative to the cavity plate 4 when the moving mold 1 separates from the stationary mold 2.

[0020] As a further provision of the above scheme, the core-pulling mechanism 5 includes a movable plate 52 and a core plate 54 fixed to the movable plate 52. A push plate 51 with a slope that cooperates with the inclined surface of the movable plate 52 on the outward side is provided on the movable plate 52.

[0021] As a further feature of the above scheme, the guide plate 53 is fixedly connected to the moving mold 1 and is provided with a sloping part 56. The movable plate 52 is also provided with a sloping opening 57, and the sloping part 56 and the sloping opening 57 are matched and configured.

[0022] As a further feature of the above scheme, the movable plate 52 is provided with sliding ribs 521 on both sides, and pressure plates 522 are bolted to the flow channel plate 3 relative to the two sides of the movable plate 52. The pressure plates 522 form a sliding groove 523 on the flow channel plate 3, and the sliding ribs 521 move relative to the flow channel plate 3 based on the sliding ribs 521 and the sliding grooves 523.

[0023] As a further provision of the above scheme, the flow channel plate 3 is provided with an injection flow channel 63, and the moving mold 1 is also provided with a flow divider plate 8 and a hot nozzle 7. One end of the hot nozzle 7 abuts against the injection port of the flow divider plate 8, and the other end is connected to the injection flow channel 63.

[0024] As a further provision of the above scheme, the cavity plate 4 includes a moving template 42 and a stationary template 41 that interlock to form a mold cavity 6. The mold cavity 6 is also provided with a runner 61, which is opposite to the injection runner 63 on the runner plate 3.

[0025] refer to Figure 1-5 The injection mold for the pen reservoir shown in this embodiment has a core-pulling mechanism 5 installed inside, utilizing, as shown in... Figure 4The guide plate 53 connected to the moving mold 1 shown cooperates with the movable plate 52, which can only slide along the direction of the slide groove 523 due to the restriction of the sliding edge 521 and the slide groove 523. When the moving mold 1 separates from the stationary mold 2, it pulls the guide plate 53. With the cooperation of the inclined surface 56 provided on the guide plate 53 and the inclined surface opening 57 of the movable plate 52, the mold separation and core pulling are realized at the same time. Compared with the existing technology, the two steps are integrated into one, reducing the number of working steps and improving production efficiency.

[0026] Furthermore, a slope structure is provided on one side of the movable plate 52, which cooperates with the push plate 51, which is also fixed to the moving mold 1 on its outer side. When the mold is closed, the slopes of the two cooperate, and the push plate 51 drives the movable plate 52, core plate 54 and core rod to move towards the mold cavity 6 as the moving mold 1 moves towards the stationary mold 2, so as to place the core rod into the mold cavity 6.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
