Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a rotary two-color molding mold. Background Art

[0002] The silicone solid hot pressing process uses the temperature and pressure of the hydraulic press to vulcanize and mold the product with the help of the mold. This process is relatively low in cost, high in output, and widely used. It is mostly used for single-color silicone products, and can also be applied to two-color and double-hardness products or multi-color and multi-hardness products. However, it is limited by the structure and color of the product, the mold structure is not flexible, the production mold and process are complicated, the production cycle time is long, and the efficiency is low.

[0003] At present, the general practices of two-color or multi-color molding are:

[0004] (1) Multi-color pellets: First, mold the rubber material of color A or different hardness once, remove the burrs, then put it into the finished product mold, put it into the correct position in the mold cavity, then put the rubber material of color B or hardness, and then mold it again to combine the two. The disadvantages of this method are: there are many molds, at least two sets must be made, the cost is high, the efficiency of placing pellets is low, and it is easy to produce defective products.

[0005] (2) Dual-color mold transfer: This is an improvement over the previous method. One set of molds is used to make two middle plates. First, the A color or hardness is vulcanized and formed. The middle plate is manually removed and then another mold is replaced to mold the B color or rubber material. The disadvantages are: two middle plates need to be made, the action of changing the middle plate is complicated, the labor intensity is high, and the efficiency is low. Utility Model Content

[0006] The technical problem to be solved by the utility model is that the existing two-color or multi-color molding process is complicated, the production cycle time is long, and the efficiency is low.

[0008] As a further improvement of the utility model, the bearing is located at the center of the bottom of the lower die seat, and a bearing groove for installing the bearing is provided on the bottom plate.

[0009] As a further improvement of the utility model, a plurality of cavity spaces for molding two-color watchband products are formed between the lower mold base and the upper mold base, and the plurality of cavity spaces are divided into two groups and are centrally symmetrically arranged about the bearing.

[0010] As a further improvement of the utility model, an arc-shaped guide groove is provided at the bottom of the lower mold base, the center of the arc-shaped guide groove is the bearing center and the arc of the arc-shaped guide groove is 180°, and a guide column is fixedly connected to the bottom plate and the guide column cooperates with the arc-shaped guide groove.

[0011] As a further improvement of the utility model, the two positioning blocks are arranged symmetrically about the bearing.

[0012] As a further improvement of the utility model, both ends of the bottom plate are provided with a first card slot for the card block to be engaged, and both ends of the bottom of the lower mold base are provided with a second card slot for the card block to be engaged.

[0013] As a further improvement of the utility model, a plurality of positioning columns are fixedly connected to the top of the lower die base, and a positioning groove matching with the positioning columns is provided at the bottom of the upper die base.

[0014] The beneficial effects of the utility model are as follows: the utility model is suitable for the molding of products with dual colors, dual hardness and dual materials. Compared with the traditional molding method, it reduces the number of molds, reduces the intensity of workers, improves work efficiency, and at the same time improves the yield rate of products and reduces production costs.
