Description
Technical Field
The utility model belongs to the technical field of the ACC sign mould, a zero offset gating system of ACC sign is related to.
Background
The ACC radar wave transmitting sign is a novel product for intelligent development of automobiles, relates to the induction range and the induction sensitivity of radar waves, and influences the safety performance of intelligent driving of automobiles. According to the ACC (adaptive cruise control) transparent radar wave sign product, due to the requirement of transparent radar waves, the size and the appearance of the product have high requirements, the conventional injection molding technology cannot meet the customer requirements, and particularly, the flatness and the contour size of the transparent wave surface of the product are directly influenced by the position and the structure of a sprue, so that the accuracy and the safety performance of the transparent radar waves of the ACC sign are influenced. The arrangement structure of the hot nozzles of a casting system is generally parallel to the mold opening direction, and because the surface of the ACC label is in a curved surface shape, when a casting gate of the casting system pours on the surface of a product, a large step of offset can be generated between the mouth part of a valve needle and the surface of the product mouth, so that the requirement on the opposite profile tolerance of the high-precision ACC label cannot be met.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem to prior art's current situation, and provide a zero disconnected poor gating system of ACC sign that injection moulding is stable.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a zero offset gating system of ACC sign for ACC sign product of moulding plastics, includes mould benevolence, hot mouth and needle, hot mouth be located mould benevolence, the needle is located hot mouth, its characterized in that, hot mouth and needle be the tilting setting in mould benevolence, hot mouth and needle slope in die sinking direction to make hot mouth, needle and ACC sign product surface become normal direction perpendicular.
In the ACC sign zero-offset casting system, the two sides of the bottom of the hot nozzle are provided with the inclined supporting edges, the hot nozzle is provided with an opening for the valve needle to pass through, a fixing port for the valve needle to extend out is arranged between the die core and the ACC sign product, and the size of the upper part of the fixing port is larger than that of the lower part of the fixing port.
Compared with the prior art, the utility model has the advantages of solve ACC and pass through radar wave product gate area unevenness and size and surpass tolerance scheduling problem, face profile degree is steerable within 0.05 of performance demand, and the action of filling of moulding plastics more does benefit to injection moulding, and the product size is more stable than traditional mode, can prevent the production of product overlap defect.
Drawings
FIG. 1 is a schematic view of the entirety of the ACC sign zero-offset gating system;
fig. 2 is an enlarged schematic view of a portion a in fig. 1.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
In the figure, a mold core 1; a hot nozzle 2; a valve needle 3; a diagonal support edge 4; an opening 5; a fixed port 6; ACC brand product 7.
As shown in fig. 1 and 2, the ACC sign zero-offset casting system is used for injection molding of ACC sign products, and comprises a mold core 1, a hot nozzle 2 and a valve needle 3, wherein the hot nozzle 2 is located in the mold core 1, the valve needle 3 is located in the hot nozzle 2, in order to ensure the stability of injection molding, a fixing position of the valve needle 3 is required to be ensured firstly, inclined supporting edges 4 are arranged on two sides of the bottom of the hot nozzle 2, the whole valve needle 3 can be ensured in the hot nozzle 2 in an inclined direction through the inclined supporting edges 4, an opening 5 for leading the valve needle 3 out is formed in the hot nozzle 2, a fixing port 6 for leading the head of the valve needle 3 to extend out is arranged between the mold core 1 and the ACC sign products 7, and the size of the upper part of the fixing port 6 is larger than that of the lower part, so that.
This patent hot mouth 2 and needle 3 are the tilting setting in mould benevolence 1, hot mouth 2 and needle 3 slope in the die sinking direction, hot mouth 2, needle 3 is a with the mutual contained angle of die sinking direction, and make hot mouth 2, needle 3 becomes normal direction perpendicular with 7 surfaces of ACC sign product, here with hot mouth 2, needle 3 assembles in mould benevolence 1, under complete assemblage state, with mould benevolence 1, hot mouth 2, whole sets of subassembly heating such as needle 3 is to 260 degrees, continuously keep temperature 30 ~ 40 minutes, make needle 3 fully be in the thermal energy state, numerical control milling machine on the maintenance heating state, through numerical control milling machine heating state contour machining, make 3 terminal surfaces of needle coincide completely with the product appearance, reach the characteristic effect of product surface no sunken step, injection moulding: based on the structural characteristics, the machining process of thermal expansion heating machining is combined, the marking of the valve needle 3 on the surface of the formed product can reach within 0.05, and the valve needle 3 is accurately molded in a profiling mode, so that the wave-transmitting high-precision performance requirement of an ACC (adaptive cruise control) label is met on key factors such as thickness tolerance, profile tolerance, appearance quality and the like, and the generation of injection molding flash of the valve needle 3 area can be avoided.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
