New description: [New technical field] [0001] The present invention relates to a mold, and more particularly to an injection mold. [Prior Art 1 [0002] According to the various tools and products used in production and life, there is a close relationship with the mold, and most of the consumer goods are plastic products. The main plastic mold is molded out. When the plastic mold is processed, the plasticized knee is washed and cast into the mold by the hanging shovel. After the mold is cooled, the mold is released and the desired product is obtained. When molding a product having a complicated shape, it is necessary to provide a corresponding structure on the injection mold, for example, molding a product 200 (as shown in the third figure), the product 200 is provided with a hole position near the edge and the hole position It is necessary to mold on the master mold of the injection mold. [0003] However, for example, if the above product 200 is provided with a hole 202 at the edge, the injection mold may be warped due to excessive tension when the mold is opened, and the portion of the product end 201 outside the hole 202 of the product 200 may be warped. The distortion of the curve increases the defective rate of the product. [New Content] [0004] The purpose of the present invention is to overcome the deficiencies in the prior art described above, and to provide an injection mold that prevents the product from being deformed when the pulling force is excessively large during mold opening. [0005] The present invention provides an injection mold comprising a master mold, a male mold that is opened or clamped correspondingly to the upper and lower sides of the master mold, and a pressing mechanism. The master mold comprises a mother template and a female mold core fixed under the mother template. The lower surface of the mother mold has a receiving hole upwardly, and the upper surface of the female mold core is opened downward with a 10120262# single number A0101 page 3 / total 12 Page 1012008122-0 M430366

[0006] In summary, the creation of the injection mold by the design of the pressing mechanism enables the mold opening to be completed in two stages, so that the product is separated from the master mold and then separated from the pressure rod of the pressing mechanism, thereby avoiding When the mold is opened, the product is deformed due to excessive tensile force of the master mold, thereby improving the yield of the product.

The upper end of the pressing rod 31 has a holding portion 311, and the holding portion 311 can be slid up and down to be placed at the limit of the female mold. In the hole 121. The lower surface of the pressing rod 31 is recessed upwardly with a slit 312, and the gap 312 is surrounded by the female mold core 12 and the male mold core 22 into a cavity (not shown). The elastic member 32 is received in the receiving hole ι of the female template ,, the upper end abuts against the bottom of the valley ill, and the lower end abuts against the upper surface of the holding portion 311. In this embodiment, the elastic member 32 is a spring. [0012] Referring to the first figure, when the original injection mold 1 is in the mold clamping state, the female mold 1 and the male mold 2 are closed, and the lower end of the pressing rod 31 of the pressing mechanism is abutted against the upper surface of the male mold φ 22 . 'And the pressing rod 3丨 is completely accommodated in the sliding hole 122 of the female mold core 12'.

The 32 is compressed and received in the receiving hole 111. [0013] Please refer to the second and third figures. In the first stage of the original injection mold, the female mold 1 moves upward relative to the male mold 2, and the elastic member 32 of the pressing mechanism recovers from the compressed state to the natural state. The pressure is generated such that the lower end of the pressure bar 31 continues to press the product end 201 of the product 200 against the upper surface of the male mold core 22. 10120262^^^^ Α0101 Page 5/Total 12 Page 1012008122-0 [0014] M430366 [0015] [0018] [0019] [0020] [0022] [0023] 10120262 Please refer to the fourth figure, 'The second stage of the mold opening of the original injection mold, the mother mold 1 continues to move upward relative to the male mold 2, causing the elastic member to open the rod 3 ιι 'the holding portion 311 of the grinding rod 31 is relatively When the mother mold ί2 slides down to the bottom of the limit hole 121, the master mold!
