Abstract

The utility model relates to a plastic part injection molding mold, which comprises two bottom plates which are in the same horizontal plane and are spaced apart, two support plates respectively mounted on the upper surfaces of the two bottom plates, a top plate fixed on the tops of the two support plates, a lower template mounted on the upper surfaces of the top plates, an upper template mounted on and matched with the lower template, and an adjustment block which is adjustably mounted between the top plate and the bottom plate and is located between the two support plates. In this way, after the plastic part is injection molded, the movement of the adjustment block can be used to drive the ejector pin to move up and down so that the molded plastic part can be easily removed from the mold cavity, which is conducive to improving production efficiency.

Description

A plastic injection molding mold

technical field

The utility model relates to a forming mold, in particular to an injection molding mold for plastic parts.

Background technique

Small parts (also known as parts or spare parts) are inseparable individual parts that make up machinery and machines, and their manufacturing process generally does not require assembly processes. For example, bushings, bearing bushes, nuts, crankshafts, blades, gears, cams, connecting rod bodies, connecting rod heads, etc. are conventional spare parts and basic units in the mechanical manufacturing process. Some small parts (especially plastic parts) require high processing precision and are small in size, which is not suitable for processing with large precision milling machines, which requires the use of injection molding molds.

Contents of the invention

The purpose of the utility model is to provide an injection molding mold for plastic parts in order to overcome the deficiencies of the prior art.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an injection molding mold for plastic parts, which includes two bottom plates arranged at intervals in the same horizontal plane, and two supporting pieces respectively installed on the upper surfaces of the two bottom plates. plate, a top plate fixed on the top of the two support plates, a lower formwork installed on the upper surface of the top plate, an upper formwork mounted on the lower formwork and matched with it, and an upper formwork that is adjustable on the top plate and the An adjustment block between the bottom plates and two support plates, a plurality of guide rods installed on the upper surface of the adjustment block and extending upwards through the top plate and the lower formwork, and installed on the adjustment The upper surface of the block extends upwards to a plurality of thimbles penetrating through the top plate and the lower template. The bottom surface of the upper template is provided with a plurality of upper molding cavities connected to each other. A plurality of lower molding cavities corresponding to the cavity and matched with the thimble, and a plurality of liquid injection holes communicating with the upper molding cavity are opened in the upper template.

Preferably, the four corners of the lower template are further provided with a plurality of limiting protrusions, and the four corners of the upper template are provided with a plurality of limiting holes matching the limiting protrusions.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art: the injection molding mold of the plastic part of the utility model can be adjusted to be installed between the top plate and the bottom plate by setting the adjustment block and positioned between the two supports between the plates, and install multiple thimbles that run through the top plate and the lower template, so that when the plastic parts are injection molded, the movement of the adjustment block can be used to drive the thimbles to move up and down so that the formed plastic parts can be easily removed from the mold cavity. Removal is conducive to improving production efficiency.
