New description: [New technical field] The ejector pin for ejector molded products, especially regarding __ reliance and injection molding dies with thimbles. [Prior Art] Press, in the mold, the top slant system is used to eject the molded article from the mold. Such as the second, the first Β _, the ordinary thimble is difficult ^ 12a Ha 〇 needle countersunk head (4) is connected as one, the other end is the light braid 12a 0] ^11«, f can be rotated around the axis 〇1, so that Ordinary thimbles are used for the top _ police 2 surface is flat...^ ^ ^ ^ ^ ^ ^ 衣0口 When the surface of the molded product is a curved surface, the ejector pin purchased by the ordinary thimble is a smooth flat end-composite The surface of the product is processed into a curved surface, and at the same time, the appearance quality of the surface of the product is required to fix the thimble in the mold to avoid scratching the surface of the molded article due to the rotation of the thimble and the second product, thereby affecting the quality of the molded product. Please refer to the second A and B diagrams, a conventional self-aligning thimble (10) ^ ^ 10 a ^ 〇τ , ^ 1 〇 b i2b upper end mating molded product table _ requirements processed into inclined surface, and will And through the thimble gamma thimble countersunk head 14a grinding a part to become a countersunk head 咐, and = M288241 - axis 10b 12b 14b Please refer to the third A, third B picture, Yuan ό ό in the mold, Rj_卜~—For the locating pin that can be positioned by itself, the locating slot l6b is milled out to a specific positioning slot l6b to locate the _ 1Gb of the _ 1Gb _14 = "Cocoa self-positioning thimble ship Turning the countersunk head 14b;; bit; 116b, it is necessary to mill a circular hole according to the head b, after the ,,,,,,,,,,,,,,,,,,, The anti-rotation countersunk head 14b is placed in the fixed position. 1Λ ^ The body is fixed: 次: The secondary processing increases the manufacturing cost of the thimble, and in order to cooperate with the thimble, the _^ inch of the mold increases the manufacturing cost of the mold. New content] This: The main purpose of i] is to provide _ seed and top + and thimble 捍-body _ column _ pin _, ^, __ ejector rod end, and the thimble is countersunk It is larger than the ejector pin eccentricity. Because of the plucking of the object; and the structure of the eccentricity of the ejector pin and the ejector pin, the difference between the processing die and the ejector pin is only the ejector pin and the thimble needle can be completed in one time, without grinding The head--, order: processing of the interdigitated thimble, thereby reducing the manufacturing cost. The other part of the creation - provided - a mold with the above-mentioned mold thimble, M288241 .U fixed plate; the mother is difficult, m is set below the upper solid There is a board in the Lai board, the mother batch, her husband, under the board, the public (4) have a training, the public and mother board are closed when the 'public, Lai Renzhi _ thin cavity; the lower jaw, located below the public template' - the partition block is connected between the lower plate and the male plate, and the pair of spacers are formed between the partitions (four); the upper ejector plate is located in the accommodating space between the spacer blocks to slide up and down, and the upper ejector plate The bottom is provided with a circular counterbore, and the upper part of the yarn is connected to the countersunk hole. • The ejector pin is eccentric with the corresponding countersunk hole, and the ejector pin is relatively interesting. The eccentricity is the same as the eccentricity of the ejector pin relative to the ejector countersunk head, and the ejector pin is topped from above The bottom of the plate passes through the countersunk hole and the ejector pin through hole and passes through the male die and the male die to meet the cavity. The ejector pin is positioned in the counterbore; and the lower ejector is fixed on the top. Fixing the ejector pin under the board. It can be seen that in order to assemble and position the ejector pin on the ejector, it is only necessary to mill a round countersunk head in the upper ejector plate of the mold to assemble. • Die thimble, she In the case of the Wei-style runway-shaped positioning groove of the prior art, the processing of the mold using the mold thimble is also simple and convenient, thereby facilitating the reduction of the manufacturing cost of the mold. [Embodiment] To explain the technical content of the creation in detail, Structural Features, Achieved Objects, and Efficacy' The following examples are set forth in the accompanying drawings. Please refer to the fourth picture, which is a cross-sectional view of the assembly of the tilting thimble 1G in the injection molding die. The injection molding die 100 includes an upper fixing plate 2〇, a mother template 30 fixed under the upper fixing plate 20, a male template 4〇 located under the mother template 3〇, and a lower fixing plate 50 fixed under the M288241 male template 40. 30 is internally fixed with a female mold core 32, and a male mold core 42 is fixedly disposed inside the male mold 4, and when the mold is closed, a mold is formed between the female mold core 32 and the male mold core 42. The molded product 2 (8) is formed in the cavity. Inside. The pair of spacer blocks are respectively arranged between the male template and the lower fixing plate 50, and a receiving space is formed between the fixed connecting template 4 and the lower fixing plate t. The upper ejector plate 62 and the lower ejector plate 64 are fixed. It is integrated and located in the accommodating space. The return needle 72 is fixed on the upper ejector plate, returning to the position 72, ^ 40 72 ^ 62.64 The ejector pin 1 〇 农 农 上 上 上 上 上 上 上 上 上 上 ^ ^ ^ ^ ^ ^ ^ ^ ^ When the mold is opened, the molded article 2 is topped, such as the fifth rider, the mold thimble 1G package _ needle bar I2 and the curved surface of the ejector pin 12-===2°0, and the bottom end is connected to the thimble. The outer rim of the 12 is also (four) touched, and the outer diameter of the thimble _ 14 is larger than the ejector pin and the ejector pin 12 is eccentric with the thimble head 14 . For example, the first ', A, ', 'B, 'B' is the first best thief in the creation of the mold thimble 1 ^ two shot 12 projection in her head 14 just 14 °4 ^ 12 ^ ° 3 ^ M288241 away. In the case of the ejector pin 12, the ejector pin 12 is offset from the ejector countersunk head 14, so that the outer warp circle 3 and the outer diameter circle 4 are not separated from the m ^ ^ port, and then the eye Γ, Ϊ ^ Π _4_ 佳 better embodiment. In the present embodiment, the other outer diameter of the needle 1 (1) is round. 4, the phase is cut. A 'sole shot for the creation of the mold thimble 1G group _ = domain' on the bottom of the butterfly 62 _ er with 14 (10) heart round ice master hole 1 2 3, 65, corresponding to the counterbore 65, ^ ^ ^ 62 ^ 12 〇3 v 〇3^ Shaped ejector pin through holes 66, 66, marriage ^65'65"4^ corresponding countersunk holes 65, 65, eccentricity, eccentricity of the ejector pin 66, 66__^, 65' The ejector pins 12, 12' are opposite to the thimble (4), the ejector pins 12, 12 of the mold thimble 1G are assembled, and the ejector pins are over-corrected through the holes 66, 66, and the thimbles are closed during the clamping. The rod ΐ2, η, passes through the male mold male puller 42 and meets the cavity of the mold, the top rail·, μ, the countersink hole 1 65', the needle stick is too secret, 6__5_ 2 6' and Xiao 65, (4) The eccentric structure can prevent the mold remaining needle b cylinder 3 】 62 __ positioning 'from _ _ _ _ needle = turn 200 〇 62 64 4 square ' thus the mold thimble 10 is up and down ejector plate 62, then set. M288241 In summary, the ejector pin 10 of the present invention is designed by the eccentricity of the ejector pins 12, 12 and the ejector countersunk heads 14, 14', the ribs 12, 12, and the thimble countersunk head 14, which are cylindrical. Therefore, the mold ejector pin 10 only needs to be formed once in the manufacturing process, and the second process of grinding the thimble head into a non-shaped shape is not required in the prior art, and only the inside of the upper ejector plate 62 of the mold 100 needs to be milled. Corresponding circular counterbore 65, that is, and the rounded head holes 65, 65, the processing of the conventional track-shaped positioning groove is also simple and convenient, thereby effectively reducing the K addition of the mold.
