Abstract
The utility model provides a injecting glue structure of plastic mould, it include the sprue and communicate in the several runner of sprue, the sprue is thicker, the internal diameter of runner diminishes gradually from being close to the sprue to keeping away from the sprue, the end of runner is equipped with the injecting glue mouth that flows in the product. The utility model discloses a plastic mould's injecting glue structure can reduce the influence to product appearance through the less injecting glue mouth of inferior runner. Meanwhile, when the mold is opened, the main runner and the secondary runner can be easily pulled away from the product, so that the production speed can be increased. Meanwhile, the whole structure of the die is optimized.
Description
Technical Field
The utility model relates to the field of molds, especially, relate to a injecting glue structure of plastic mould.
Background
At present, with the development of social economy, people have higher and higher requirements on products, and not only the requirements on good appearance are met, but also the shape and the structure of the products become more and more complex.
Plastic products are generally injection molded through a mold. And the internal structure of some products is complicated and the surface requirement is very high, so that the appearance function of the product is influenced by front glue feeding and back glue feeding in the injection molding process, and the mold opening of the whole mold becomes difficult.
SUMMERY OF THE UTILITY MODEL
An object of this technical scheme embodiment is to provide a injecting glue structure of plastic mould that does not influence product appearance when the mould sinking.
The utility model provides a injecting glue structure of plastic mould, it include the sprue and communicate in the several runner of sprue, the sprue is thicker, the internal diameter of runner diminishes gradually from being close to the sprue to keeping away from the sprue, the end of runner is equipped with the injecting glue mouth that flows in the product.
Further, the secondary flow channel is formed from a sidewall opening of the primary flow channel.
Furthermore, the secondary flow channel is vertically downward.
Furthermore, the main runner is provided with a glue inlet for injecting glue.
Furthermore, a circular truncated cone is arranged at the glue inlet.
Furthermore, the caliber of the glue inlet is gradually reduced from far to near to the main flow passage.
The utility model discloses a plastic mould's injecting glue structure can reduce the influence to product appearance through the less injecting glue mouth of inferior runner. Meanwhile, when the mold is opened, the main runner and the secondary runner can be easily pulled away from the product, so that the production speed can be increased. Meanwhile, the whole structure of the die is optimized.
Drawings
In order to more clearly illustrate the technical solution of the present invention, the drawings required to be used in the embodiments will be briefly described below, and obviously, the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a glue injection structure of a plastic mold provided by the embodiment of the utility model.
Fig. 2 is the utility model discloses injecting glue structure and the injection moulding product of plastic mould that the embodiment provided.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present technical solution, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a glue injection structure 100 for a plastic mold. The plastic mold's injecting glue structure 100 includes sprue 110 and communicates in several runner 120 of sprue 110, sprue 110 is thicker, runner 120's internal diameter diminishes gradually from being close to sprue 110, runner 110's end is equipped with the injecting glue mouth 111 that flows into the product.
The secondary flow channel 120 is formed from a sidewall opening of the primary flow channel 110.
The sub-channel 120 is vertically downward.
The main runner 110 is provided with a glue inlet 200 for injecting glue.
The glue inlet 200 is provided with a circular truncated cone 300.
The caliber of the glue inlet 200 gradually decreases from far to near to the main flow passage 110.
Referring to fig. 2, the injection opening 111 with a smaller diameter is close to the injection product, and the secondary runner is easily separated from the injection product when the mold is opened.
The utility model discloses a plastic mould's injecting glue structure can reduce the influence to product appearance through the less injecting glue mouth of inferior runner. Meanwhile, when the mold is opened, the main runner and the secondary runner can be easily pulled away from the product, so that the production speed can be increased. Meanwhile, the whole structure of the die is optimized.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
