New description: [New technical field] About this type The creation department is about a plastic injection mold, especially for plastic injection molds with oblique pin feed structure.疋[Prior Art] • 1 glue injection molding is a kind of production method widely used in industry at present. 'The adjustment of process parameters is very difficult. Plastic injection molding has quite a lot of process parameters to be adjusted 'for example, plastic temperature, injection pressure, mold temperature, When the process conditions are not properly adjusted, various defects such as plastic scorch marks, flow lines, dents, and the like are generated in the plastic injection finished product. Especially when the finished product is large in size, the glue feeding position often causes scorch marks due to excessive temperature, or the plastic temperature is insufficient. Especially when the plastic knee injection molding is applied to the in-mold transfer process, the transfer film is often damaged due to excessive temperature or excessive pressure of the plastic, so that the decorative pattern on the transfer film cannot be smoothly transferred to the finished surface. . In view of the shortcomings of the above-mentioned plastic injection mold, it is necessary to propose a plastic injection mold, the temperature of the glue injection position is not too high, causing defects on the surface of the finished product or the transfer film due to excessive plastic temperature or excessive pressure. Destruction or smashing, the decorative pattern on the transfer film can not be smoothly transferred to the surface of the 50 M320482 finished product [new content] The problem to be solved in this creation is to provide a kind of plastic injection mold, which is glued: set: degree will not If it is too high, it will cause defects on the surface of the finished product or the destruction of the transfer film due to the plastic, so that the decorative pattern on the transfer film cannot be smoothly transferred to the finished surface. Eight In order to solve the above problems, this creation proposes a plastic injection mold containing a master mold, a male mold and a skew pin. The male mold has at least one runner; the oblique pin is placed on the male mold, the oblique pin, the male mold and the female mold can jointly form a molding space and the oblique pin has a concave structure, and the concave structure A gate is connected to the runner, wherein a plastic material is filled into the molding space by the runner to form a plastic component. The effect of this creation is that the plastic injection mold with the obliquely inserted rubber structure of the present invention does not have a high temperature at the feeding position, which causes defects on the finished surface or is caused by excessive plastic temperature or excessive pressure. The destruction of the film causes the decorative image on the transfer film to be unsuccessfully transferred to the finished product table M320482. [Embodiment] The first figure shows a plastic injection mold 200 having a skew pin feeding structure according to a preferred embodiment of the present invention. The plastic injection mold 200 includes a female mold 210, a male mold 220, and a skew pin 230. The male mold 220 has at least one runner 221 and at least one ejector pin 222. The oblique pin 230 is disposed on the male mold 220, and the oblique pin 230, the male mold 220 and the female mold 210 can be combined. In the molding space, the oblique pin 230 has a recessed structure 231. The recessed structure 231 has a gate 2311 connected to the runner 231. A plastic material is filled into the molding space by the recessed structure 231 to form a recessed structure. a plastic component that forms a feed buffer structure by the recessed structure 231. When the plastic part is cooled, the male mold 220 is separated from the female mold 210, and the oblique pin 230 is separated from the plastic part by the side of the male mold 230, and then the ejector pin 222 is used to The plastic component is ejected, and finally the plastic buffer structure is removed from the plastic component. When the plastic component is ejected, the ejection pin 222 can push the plastic buffer structure. The second figure shows a schematic view of the oblique pin 230 in the first figure. The oblique pin 230 has a fitting plane 232 for attaching to the male mold 220. When the rubber enters the space formed by the concave structure 231 and the male mold 220 through the gate 2311, the mold and the mold The gas entrained by the compound can be discharged by the gap between the bonding plane 7 M320482 232 and the male mold 220. The recessed structure 231 includes a buffering area 2312 and a feeding area 2313. The buffering area 2312 is a long strip-shaped space extending perpendicularly to the direction of injection, and the feeding area 2313 is a space in which the cross-sectional area is gradually reduced. When the material is injected from the gate 2311, the temperature and pressure can be relaxed in the recessed structure 231, and then the space formed by the injection of the master mold 210 and the male mold 220 is stabilized by the rubber feed region 2313 whose cross-sectional area is gradually reduced. The third figure shows the plastic buffer structure of the plastic part in the first figure. The feeding buffer structure 250 includes a buffer structure 251 and a feeding structure 252. The buffer structure 251 has a long outer shape, and the feeding structure 252 has a shape with a gradually decreasing cross-sectional area, since the feeding structure 252 has When the cross-sectional area is gradually reduced, the position of the feeding structure 252 can be easily broken when the plastic buffering structure of the plastic part is to be removed. By the plastic injection mold with the oblique pin into the plastic structure, the temperature of the feeding position is not too high, and the defects of the finished surface are not caused by the excessive temperature of the plastic or the excessive pressure, thereby causing the in-mold transfer process. The destruction of the transfer film, so that the decorative pattern on the transfer film cannot be smoothly transferred to the finished product table M320482.
