[0002] Currently, coffee machine knobs are typically used to control different functions of the machine. The specific design varies depending on the brand and model, and they are usually made of plastic and injection molded. For example... Figure 1 As shown, because the center of the knob needs to connect to the lever on the coffee machine, its center has a cavity structure and a lever mounting cavity structure for assembly with the lever. Since there is no corresponding injection mold in the prior art, this application provides an injection mold for a coffee machine knob to injection mold the above-mentioned structure. Utility Model Content

[0003] The purpose of this invention is to provide an injection mold for a coffee machine knob, which has a simple and reasonable structure, stable and reliable operation, can be efficiently injection molded and quickly demolded, and can injection mold a coffee machine knob with a square hole in the middle for mounting a rotating rod, making it convenient to connect with the rotating rod.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An injection mold for a coffee machine knob includes a left mounting base, a right mounting base, a left mold assembly, a right mold assembly, and a demolding assembly;

[0006] Since the molds in this application are generally placed horizontally in the injection molding machine, the description is based on their positional relationship in use, with the left-side mounting on the left side as an example (but not limited to this mounting method).

[0007] The left mounting base includes a left end plate, a connecting plate, and guide rods; the left end plate is vertically arranged, and its right side is connected to the vertically arranged connecting plate, which consists of two opposing, spaced-apart connecting plates; two guide rods are horizontally arranged on the right side of the connecting plate.

[0008] The right side of the left mounting base is fixed to the horizontally arranged demolding assembly; the right end face of the connecting plate is connected to the left mold assembly;

[0009] The left mold assembly includes a left mold base, a left mold, and a mold core. The left mold base is vertically arranged and is a square plate with a recessed cavity on its right end face. The left mold is embedded in the recessed cavity. The left mold has several raised mold cores. A core rod is horizontally arranged in the middle of the mold core. The outer edge of the mold core has a glue inlet hole and an ejector pin hole.

[0010] The demolding assembly includes a cylinder, a compression spring, demolding ejector pins, guide pillars, and a push base. The push base is vertically positioned, with several demolding ejector pins horizontally arranged on its right end face. The number of demolding ejector pins matches the number of knob-shaped mold cavities. Four guide pillars are also horizontally arranged on the right end face of the push base, and the cylinder is slidably connected to the guide pillars. The compression spring is sleeved on the outer wall of the guide pillars, with its left and right ends respectively abutting the push base and the left mold base. The cylinder is horizontally positioned, and its output shaft is connected to the left end face of the push base.

[0011] The right mold assembly includes a right mold base and a right mold. The right mold base is vertically arranged, and its left end face has a second recess, within which the right mold is tightly fitted. The left end face of the right mold has several forming cavities. (When the left and right mold assemblies are assembled and the mold is closed) the mold core is inserted into the forming cavity, and there is a gap between the mold core and the forming cavity, which is the knob forming cavity. The gap area formed by the mold core, the forming cavity, and the core rod constitutes the outer shape of the knob.

[0012] The left mold has an ejector pin cavity in the middle, and the right end of the ejector pin is located inside the ejector pin cavity.
