Description

Technical Field

[0001] This utility model relates to the field of plastic product processing machinery, and in particular to a pre-heated runner multi-station vertical injection molding machine in injection molding equipment manufacturing technology. Background Technology

[0002] With the continuous improvement of living standards and the development of the plastics industry, plastic products are used in various fields of life and production, leading to increasingly higher requirements for the shape of plastic products. Plastic products are mainly formed by injection molding. Injection molding equipment is divided into two types: horizontal and vertical. During the processing, plastic granules are melted as they are pushed through a spiral ejector tube and then enter the mold to be formed. A hot runner system on the lower mold ensures that the molten plastic flows evenly between the upper and lower molds throughout the entire mold cavity. From the existing structure, a hot runner system must be installed on the lower mold of each mold to ensure the even flow of molten plastic granules between the upper and lower molds. For large multi-station injection molding machines, a hot runner system needs to be configured in the upper and lower molds of each station, thus increasing the overall complexity of the machine. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a front-runner multi-station vertical injection molding machine.

[0004] This utility model is achieved through the following technical solution: a front-mounted hot runner multi-station vertical injection molding machine, mainly composed of a machine base, a hopper, a spiral pusher pipe and a lifting platform. The hopper is located at the top of the machine base, the spiral pusher pipe is installed below the hopper and vertically downwards, and the lifting platform is located on the working platform below the spiral pusher pipe; it also includes a hot runner module, which is located above the lifting platform and fixed at the nozzle at the bottom of the spiral pusher pipe.

[0005] The hot runner module has multiple plastic output points;

[0006] There should be at least 20 cm of vertical space between the lifting platform and the hot runner module;

[0007] The hot runner module is provided with a hot runner channel that connects to the outside world.

[0008] This invention, by installing a hot runner module at the nozzle of the spiral push rod channel, ensures that the molten plastic liquid entering the entire mold cavity of the upper and lower molds maintains good fluidity, eliminating the need for a hot runner system on the lower mold and simplifying the machine structure, especially in large multi-station injection molding machines.

[0011] Appendix Figure 3 This is a schematic diagram of the structure of Embodiment 2 of this utility model. Detailed Implementation

[0012] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model.

[0013] like Figures 1 to 2 As shown in Embodiment 1 of this utility model, a front-mounted hot runner multi-station vertical injection molding machine mainly consists of a machine base 1, a hopper 2, a spiral pusher pipe 3, and a lifting platform 4. The hopper 2 is located at the top of the machine base 1, the spiral pusher pipe 3 is installed below the hopper and vertically downwards, and the lifting platform 4 is located on a working platform below the spiral pusher pipe 3. It also includes a hot runner module 5, which is located above the lifting platform 4 and fixed at the nozzle at the bottom of the spiral pusher pipe 3.

[0014] The hot runner module 5 has multiple plastic output points 51;

[0015] There is at least a 20cm vertical space between the lifting platform 4 and the hot runner module 5;

[0016] The hot runner module 5 is provided with a hot runner channel 52 that connects to the outside world.

[0017] In Application Example 1, the spiral pusher pipe 3 pushes the plastic granules poured from the hopper 2 above the machine platform 1, melting them during the pushing process. After passing through the nozzle at the bottom of the spiral pusher pipe 3, the granules are squeezed into the hot runner module 5. Since the hot runner channel 52, which is connected to the outside, provides heat energy, the molten plastic liquid entering the hot runner module 5 is reheated and injected into the mold cavity of the mold composed of upper and lower molds, which is located in the vertical space between the lifting platform 4 and the hot runner module 5, through multiple plastic output points 51 of the hot runner module 5. This ensures good fluidity of the molten plastic liquid injected into the mold cavity, eliminating the need for a hot runner system on the lower mold and simplifying the machine structure.

[0018] like Figures 2 to 3As shown in Embodiment 2 of this utility model, when multiple lifting platforms 4 are provided on the turntable 6, the hot runner module 5 can eliminate the hot runner system on each lifting platform 4 on the turntable 6, greatly simplifying the structure of the machine's hot runner system.
