The utility model provides a technical scheme that its technical problem adopted is: a PCB-Holder injection mold of a smart phone touch screen pen comprises an even number of mold cores, wherein each mold core comprises an even number of pairs of a fixed mold insert and a movable mold insert which are oppositely arranged, mold cavities are formed in the combined parts of the fixed mold insert and the movable mold insert, guide blocks are arranged on the two sides of the mold cavity of the movable mold insert, the guide blocks are arranged on a movable mold slide block, a movable mold inclined top is arranged below the mold cavity of the movable mold insert, and the lower end of the movable mold inclined top is arranged on a fixed block; the fixed mold insert is provided with a plurality of coarse exhaust grooves parallel to the mold cavity of the fixed mold insert and a plurality of fine exhaust grooves vertical to the mold cavity of the fixed mold insert, and the coarse exhaust grooves and the fine exhaust grooves are uniformly distributed on the fixed mold insert.

Molten plastic flows into the mold cavities of the fixed mold insert and the movable mold insert through the sprue, the guide block is driven to move by the movable mold slide block, so that the mold cavities are uniformly filled with the material, and after the plastic is formed, the product is ejected by the inclined top of the movable mold, is easy to separate and take out, and is suitable for automatic production; set up thick exhaust groove and smart exhaust groove, and both evenly distributed have optimized bad problems such as multicavity product is stranded gas and is burnt on the cover half mold insert.

Preferably, the depth of the coarse exhaust groove is 0.1 mm.

Preferably, the depth of the fine exhaust groove is 0.01 mm.

Preferably, the distance between two adjacent fine exhaust grooves is 7 mm.

Further defined, the movable mold slide is mounted on a slide mount.

In order to ensure that the mould is tightly arranged and further limited, the injection mould is provided with four mould cores, and each mould core is provided with four pairs of fixed mould inserts and movable mould inserts which are oppositely arranged.

The utility model has the advantages that: the mould of the utility model has the advantages of compact arrangement and reasonable design, optimizes the bad problems of air trapping, burning and the like of multi-cavity products, and ensures a good exhaust system; the product is easy to eject, is suitable for automatic production, ensures subsequent production, effectively reduces the waste of artificial resources and ensures the quality of the final product.
