Description

Technical Field

[0002] Injection mold, also known as plastic mold or injection mold, is a sixteen-cavity gauge block injection mold special tool for producing plastic products. It consists of multiple parts, including movable mold, fixed mold, gate system, cooling system, guide mechanism, etc. The working principle of injection mold is to use high pressure to inject molten plastic material into the mold cavity, and then mold the plastic into the desired shape through cooling and solidification process.

[0003] In the production process of track gauge blocks, the number of cavities in the mold is crucial to production efficiency and cost control. At present, the number of cavities in the track gauge block mold is relatively small, which leads to a long production cycle of a single mold during the injection molding production process, thereby reducing the overall production efficiency. In addition, due to the insufficient number of cavities in the mold, the mold may need to be replaced frequently during the production process, which not only increases the operating cost, but also prolongs the time consumption, further reducing the production efficiency. Utility Model Content

At present, the number of holes in the gauge block mold is relatively small, which leads to a long production cycle of a single mold during the injection molding production process, thereby reducing the overall production efficiency. In addition, due to the insufficient number of holes in the mold, the mold may need to be frequently replaced during the production process, which not only increases the operating cost, but also prolongs the time consumption, further reducing the problem of production efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sixteen-hole gauge block injection mold, comprising a fixed mold plate, a movable mold plate and a gauge block, the middle parts of the inner surfaces of the fixed mold plate and the movable mold plate are provided with a raw material groove, and there are sixteen of the raw material grooves and the gauge block, and the outer surface of the fixed mold plate is fixedly connected to a hot runner plate, and an open hot runner system is provided inside the hot runner plate, and openings are provided at both ends of the open hot runner system, and there are four openings.

Through this design, the mold can produce 16 products at the same time during a single injection molding process, greatly improving production efficiency and effectively avoiding the problem that the number of mold cavities is crucial to production efficiency and cost control during the production of the gauge block. At present, the number of cavities in the gauge block mold is relatively small, which results in a longer production cycle for a single mold during the injection molding production process, thereby reducing the overall production efficiency. In addition, due to the insufficient number of cavities in the mold, the mold may need to be replaced frequently during the production process, which not only increases operating costs, but also prolongs time consumption, further reducing production efficiency.

[0014] 2. The utility model adopts a hot runner to cold runner glue feeding system. This design can reduce the waste of raw materials as much as possible. The hot runner system evenly distributes the molten plastic raw materials to each mold cavity, while the cold runner system returns the excess plastic raw materials to the raw material tank, realizing the full utilization of the raw materials.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-11 The utility model provides a technical solution for a sixteen-hole gauge block injection mold: a sixteen-hole gauge block 10 injection mold, including a fixed mold plate 3, a movable mold plate 4 and a gauge block 10, the middle part of the inner surface of the fixed mold plate 3 and the movable mold plate 4 are provided with a raw material groove 8, and there are sixteen raw material grooves 8 and gauge block 10, and the outer surface of the fixed mold plate 3 is fixedly connected with a hot runner plate 2, and an open hot runner system 9 is provided inside the hot runner plate 2. The two ends of the open hot runner system 9 are provided with openings, and there are four openings. By adopting a 4-point open hot runner system 9 to feed the glue, the mold layout is optimized, and the runner weight is effectively reduced, thereby reducing the production cost. In addition, the design of the open hot runner system 9 enables the raw material groove 8 to accommodate more plastic raw materials, thereby improving the production efficiency. Through this design, the mold can produce 16 products at the same time during a single injection molding process, which greatly improves the production efficiency and effectively avoids the production process of the gauge block 10. The number of mold holes is crucial to production efficiency and cost control. At present, the number of cavities of the gauge block 10 mold is relatively small, which leads to a long production cycle of a single mold during the injection molding production process, thereby reducing the overall production efficiency. In addition, due to the insufficient number of cavities of the mold, the mold may need to be frequently replaced during the production process, which not only increases the operating cost, but also prolongs the time consumption, further reducing the problem of production efficiency. By adopting a hot runner to cold runner injection system, this design can minimize the waste of raw materials. The hot runner system evenly distributes the molten plastic raw material to each mold cavity, while the cold runner system returns the excess plastic raw material to the raw material tank 8, realizing the full utilization of the raw material. This design not only improves production efficiency, but also reduces the waste of raw materials, and has significant economic benefits.

[0031] In the present invention, preferably, the outer surface of the hot runner plate 2 is fixedly connected with the fixed mold plate 1 .

[0032] In the present invention, preferably, both ends of the outer surface of the movable platen 4 are slidably connected with ejector panels 5 , and a spring structure is provided between the ejector panel 5 and the movable platen 4 .

[0033] In the present invention, preferably, an ejector floor 6 is provided on the outer side of the ejector panel 5 .

[0034] In the present invention, preferably, the outer side of the ejector floor 6 is fixedly connected with a movable mold fixing plate 7 .

[0035] In the present invention, preferably, pin holes are provided at four corners of the inner surfaces of the movable die plate 4 and the fixed die plate 3 .

[0036] In the present invention, preferably, the pins are connected to the pin holes, and the structural components of the present invention are tightly matched, ensuring the stability and durability of the mold. In addition, the design of the mold fully considers the cooling and exhaust requirements during the injection molding process, and improves the molding quality and dimensional accuracy of the product. Through this design, the mold can produce high-quality track gauge blocks 10 to meet market demand.

[0037] The working principle and use process of the utility model are as follows: when in use, the fixed plate 3 and the movable plate 4 are installed on the injection molding machine, and the middle part of the inner surface of the fixed plate 3 and the movable plate 4 is ensured to be aligned with the mold mounting seat of the injection molding machine. Then, the gauge block 10 is placed in the raw material groove 8 of the fixed plate 3 and the movable plate 4 to ensure that the positioning of the gauge block 10 is accurate. Next, the injection molding machine is started to heat the open hot runner system 9 in the hot runner plate 2 to melt the plastic raw material. When the plastic raw material is melted, the open hot runner system 9 in the hot runner plate 2 injects the molten plastic raw material into the raw material groove 8 of the fixed plate 3 and the movable plate 4 through four openings, and performs injection molding with the gauge block 10. After the injection molding is completed, the spring structure between the ejector panel 5 and the movable plate 4 separates the ejector panel 5 and the movable plate 4, so that the ejector on the ejector panel 5 contacts the gauge block 10, and the gauge block 10 is ejected. Finally, the ejected gauge block 10 is taken out, and the above steps are repeated to continue the injection molding production. Through the above-mentioned use process, the continuous production of the injection mold of the sixteen-hole gauge block 10 can be achieved, thereby improving the production efficiency.
