Technical Field
[0001] The utility model relates to the technical field of molds, in particular to an injection mold. Background Art
[0002] A plastic mold is a tool for producing plastic products. It is composed of several groups of parts, and there is a molding cavity in this combination. During injection molding, the mold is clamped on the injection molding machine, and the molten plastic is injected into the molding cavity, where it is cooled and shaped. Then the upper and lower molds are separated, and the product is ejected from the mold cavity by the ejection system. Finally, the mold is closed for the next injection molding. The entire injection molding process is carried out in a cycle.
[0003] Traditionally, when injecting glue into the mold cavity of the injection molding machine, the glue feeding device is used to feed glue from the side or bottom of the mold cavity. This will leave glue heads on the molded product. When demolding, the glue device can only demold synchronously with the upper and lower molds, which makes the operation difficult and inconvenient for demolding. It is only applicable to some products, and demolding must be performed by a pulling mechanism or an ejection mechanism. Utility Model Content

[0005] To this end, one purpose of the utility model is to propose a glue injection mold structure in a slider, including an upper mold and a lower mold, and also including a first slider slidably connected to the lower mold, the first slider is provided with a glue injection channel arranged along the sliding direction of the first slider, and the end of the glue injection channel is provided with a glue injection groove.
[0006] Preferably, the glue inlet flow channel is provided with a protrusion, and the upper mold is provided with a first groove matching the protrusion.
[0007] Preferably, a first molding cavity is provided on one side of the first sliding block, and the glue feed channel is connected to the first molding cavity and the other end is connected to the glue feed groove.
[0008] Preferably, the upper mold is provided with a second groove matching the glue inlet groove, the second groove cooperates with the glue inlet groove to form a glue inlet cavity, and the glue inlet cavity is in communication with the glue inlet flow channel.
[0009] Preferably, the cross-sections of the glue inlet cavity and the glue inlet channel gradually increase along the sliding direction of the first sliding block.
[0010] Preferably, a glue inlet is provided at the bottom of the second groove, and a glue inlet pipe connected to the glue inlet is provided at the upper mold.
[0011] Preferably, it further comprises a second sliding block, wherein the second sliding block is provided with a second molding cavity opposite to the first molding cavity.
[0012] The above technical solution has the following advantages or beneficial effects: by directly setting the glue feed channel along the sliding direction on the first slider, that is, the glue feed channel is set on the first slider, that is, the selection of the glue feed position is not affected by the slider factor, and it is suitable for product structures with complex shapes or multiple sliders. Due to the glue feed channel along the sliding direction, when the sliders in other directions or the upper and lower molds are separated, the glue feed channel will fix the mold, and the glue port and the product are formed, and finally, demolding can be achieved without the need for an additional pulling mechanism or ejection mechanism.
