The invention relates to a straight ejector and inclined ejector combining structure for an injection mould. The straight ejector and inclined ejector combining structure is characterized by comprising a straight ejector part, an inclined ejector part matched with the straight ejector part, and an elastic mould opening auxiliary structure. The straight ejector part comprises a straight ejector block, a guide rail and ejector rods. The guide rail is arranged at the lower end of the straight ejector block. The ejector rods are arranged at the lower end of the guide rail. A first mould opening surface is arranged on one side of the straight ejector block. A first spacing hole penetrating through the first mould opening surface is formed in the straight ejector block. The inclined ejector part comprises an inclined ejector block and an inclined guide rod. The inclined guide rod is fixed at the lower end of the inclined ejector block. The inclined ejector block is provided with a second mould opening surface matched with the first mould opening surface. A second spacing hole penetrating through the second mould opening surface is formed in the inclined ejector block. A guiding groove matched with the guide rail is formed in the inclined ejector block. The inclined guide rod extends downwards obliquely in a direction close to the straight ejector block. The mould opening auxiliary structure comprises a spring part. One end of the spring part is sleeved by the first spacing hole. The other end of the spring part is sleeved by the second spacing hole. The straight ejector and inclined ejector combining structure is simple, and high in stability, and can meet the production requirement of complex products.
