Problems solved by technology
The conventional method is to make two sets of hot runner systems (including the manifold and the manifold fixing plate), which are suitable for parallel and angle two-color injection molding machines. The hot runner manifold can only be replaced by the mold. Specifically, the cylinder head, piston, valve needle, fixed mold bottom plate, manifold and hot nozzle need to be removed in sequence. After that, the hot nozzle needs to be removed from the manifold and installed on another manifold. board, and then assemble the mold in sequence. This method takes a long time to convert (the hot nozzle needs to be heated until the plastic is melted to remove it), low efficiency, high cost, and requires professional hot runner engineers to operate, resulting in an increase in mold costs. seriously affect the production efficiency

Embodiment Construction
[0015] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0016] Reference Figure 1 to Figure 5 , This embodiment can be converted into a two-color injection mold in the form of plastic injection, including a fixed mold 10 and a movable mold 20. The structure of the fixed mold 10 and the movable mold 20 is the same as the two-color injection mold suitable for parallel two-color injection molding machines in the prior art. The improvement of the two-color injection mold of the embodiment mainly involves the side of the fixed mold 10, so the structure of the movable mold 20 will not be repeated; specifically, the fixed mold bottom plate 13 is provided with a first parallel injection port 131 and a second parallel injection mold. Glue inlet 132, the first parallel glue inlet 131 is the glue inlet of the first hot runner system 11 on the fixed mold 10, and the second parallel glue inlet 132 is the...

The present invention proposes a two-color injection mold with a convertible glue feeding form. The bottom plate of the fixed mold is provided with a first parallel glue inlet and a second parallel glue inlet, and the bottom plate of the fixed mold is detachable towards the side of the fixed template of the injection molding machine. A hot runner conversion device is fixedly connected to the ground, and the hot runner conversion device includes a first angled glue inlet coaxially arranged with the first parallel glue inlet and communicated with the first parallel glue inlet, and a second angle glue inlet connected to the second parallel glue inlet. The axis of the parallel glue inlet is vertical and connected to the second angle glue inlet of the second parallel glue inlet. The invention can make the original mold that only realizes parallel glue feeding suitable for angle-type two-color injection molding machines to realize corner glue feeding, and the conversion between parallel glue feeding and angle glue feeding is easy to operate, high in efficiency, and less labor intensive for operators. The operating level is low.
Description
Technical field [0001] The invention relates to a two-color injection mold that can be converted into a plastic injection form, in particular to a conversion operation suitable for conversion between a parallel injection molding machine and an angle injection molding machine, with high efficiency, low cost, easy operation, and requirements for the operation level of operators Low two-color injection mold. Background technique [0002] In order to reduce mold costs and meet customers' needs for mold versatility, current two-color molds can be applied to both parallel two-color injection molding machines and angular two-color injection molding machines. The conventional method is to make two sets of hot runner systems (including the manifold and the manifold fixing plate), which are respectively suitable for parallel and angular two-color injection molding machines. With this approach, the applicable injection molding machine needs to be deeply disassembled. The hot runner manifol...
