Description

Technical Field

[0001] The utility model relates to the technical field of knife and fork combination injection molds, in particular to a knife and fork combination injection mold with a positioning mechanism. Background Art

[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and then cooling and solidifying to obtain a molded product.

[0003] The existing small knife and fork combination injection mold needs to be manually aligned and connected when used, and then the injection mold is fixed using an extrusion device before the injection molding operation can be completed. Since the injection mold does not have a positioning function, the accuracy of manual alignment and connection is not high enough, which leads to the quality of the injection molded product not meeting the expected effect. Therefore, the existing small knife and fork combination injection mold has inconveniences in alignment and connection. For this reason, we provide a knife and fork combination injection mold with a positioning mechanism. Utility Model Content

[0006] As a preferred embodiment, one end of the threaded rod is fixedly connected to a rotating block, and an end of the threaded rod away from the rotating block is provided with a fixing ring, the fixing ring penetrates the outer surface of the threaded rod, and the fixing ring is fixedly connected to the threaded rod.

[0007] As a preferred embodiment, a connecting block is fixedly connected to one side of the fixing ring, one end of the connecting block is fixedly connected to a limiting block, and a limiting groove matching the limiting block and the connecting block is formed on the first mold.

[0008] As a preferred embodiment, the first mold is provided with four positioning grooves, and a positioning block is fixedly connected to a side of the second mold close to the first mold.

[0009] As a preferred embodiment, a clamping block is fixedly connected to the outer surface of the second mold, and a placement groove matching the clamping block is provided on the first mold.

[0010] As a preferred implementation, the sliding block is provided with a slot that fits with the protruding portion of the card block.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model provides a positioning groove on the first mold and a positioning block on the second mold, so that the first mold and the second mold are aligned more conveniently and stably, which not only ensures the accuracy of the alignment of the two, but also improves the quality of the product after injection molding, thereby greatly improving the actual use effect of the knife and fork combination injection mold. The adjustment mechanism is provided so that the clamping block in the adjustment mechanism can be tightly clamped under the adjustment of the threaded rod, and the release of the clamping block is also convenient.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0022] Example 1

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a technical solution: a knife and fork combination injection mold with a positioning mechanism, comprising: a first mold 1, a second mold 3 is provided on one side of the first mold 1, an adjusting mechanism 2 is provided inside the first mold 1, the adjusting mechanism 2 comprises a threaded rod 21, the threaded rod 21 runs through the inside of the first mold 1, a slider 22 is passed through the outer surface of the threaded rod 21, the number of the sliders 22 is two, the slider 22 is slidably connected to the threaded rod 21, a thread groove matching the threaded rod 21 is provided on the slider 22, one end of the threaded rod 21 is fixedly connected to a rotating block 23, an end of the threaded rod 21 away from the rotating block 23 is provided with a fixing ring 24, the fixing ring 24 runs through the outer surface of the threaded rod 21, the fixing ring 24 is fixedly connected to the threaded rod 21, a connecting block 25 is fixedly connected to one side of the fixing ring 24, one end of the connecting block 25 is fixedly connected to a limiting block 26, and a limiting groove matching the limiting block 26 and the connecting block 25 is provided on the first mold 1.

[0024] In this embodiment, by setting up the adjustment mechanism 2, the connection between the first mold 1 and the second mold 3 is made tighter and more stable, ensuring that the first mold 1 and the second mold 3 will not be displaced during use, thereby improving the quality of the product formed in the injection mold. By rotating the rotating block 23 on one side of the first mold 1, the slider 22 can be threadedly driven by driving the threaded rod 21 to rotate, so that the two sliders 22 can slide in the same direction or in opposite directions at the same time, and the clamping block 5 on the second mold 3 can be engaged or released. A fixing ring 24, a connecting block 25 and a limit block 26 are set, and the limit block 26 will rotate in the limit groove opened on the first mold 1, so as to ensure the stability of the rotation of the threaded rod 21.

[0025] Example 2

[0026] like Figure 1-Figure 3As shown, the first mold 1 is provided with positioning grooves 6, and the number of the positioning grooves 6 is four. A positioning block 4 is fixedly connected to a side of the second mold 3 close to the first mold 1, and a clamping block 5 is fixedly connected to the outer surface of the second mold 3. A placement groove that matches the clamping block 5 is provided on the first mold 1, and a clamping groove that matches the protruding part of the clamping block 5 is provided on the slider 22.

[0027] In this embodiment, by providing the positioning block 4 and the positioning groove 6, the alignment of the first mold 1 and the second mold 3 is more consistent and more convenient. As long as the positioning block 4 is matched with the positioning groove 6, the quality of the product after mold injection can be guaranteed. The clamping block 5 is provided on the second mold 3, and a clamping groove that matches the clamping block 5 is provided on the slider 22, so that the second mold 3 can be tightly connected with the first mold 1 through the adjustment mechanism 2.

[0028] Working principle:

[0029] like Figure 1-Figure 4 As shown, when the utility model is in use, the second mold 3 is first aligned with the first mold 1. During the alignment, the positioning block 4 will enter the interior of the positioning groove 6, and the clamping block 5 on the second mold 3 will enter the placement groove opened on the first mold 1. At this time, the fixed clamping block 5 is tightly engaged through the adjusting mechanism 2. The rotating block 23 is rotated first, and the threaded rod 21 is driven to rotate. When the threaded rod 21 rotates, the slider 22 is threadedly driven, so that the two sliders 22 slide on the threaded rod 21 and gradually approach the clamping block 5 until the clamping groove on the slider 22 is tightly engaged with the protruding part of the clamping block 5. At the same time, the threaded rod 21 will drive the fixing ring 24, the connecting block 25 and the limit block 26 to rotate, and the limit block 26 will rotate in the limit groove opened on the first mold 1, thereby ensuring the stability of the rotation of the threaded rod 21. Finally, after the first mold 1 and the second mold 3 are aligned and connected, the injection molding operation can be carried out.
