Abstract
The invention discloses an injection mold for an automobile damping disc. An inner core of the automobile damping disc is a circular iron part with a middle hole in the axial direction; the iron part is coated with a hard plastic material; the surface of the hard plastic material on one side of the automobile damping disc is a stepped ring surface which is gradually deepened from the outside to the inside; and the surface of the hard plastic material on the other side is a curved ring surface in streamlined transition from the outside to the inside, and the hard plastic material coats the edge of the middle hole. Particularly, the injection mold consists of an upper mold, a lower mold and a discharging clamp, wherein a bottom cavity which corresponds to the stepped ring surface and a carrier table which corresponds to the circular iron part are arranged on the lower mold; a top cavity which corresponds to the curved ring surface is formed in the upper mold; and the discharging clamp is arranged in the upper mold to be aligned with the carrier table and is coaxial with the center of the automobile damping disc. According to the injection mold disclosed by the invention, the cold shrinkage phenomenon of the coated hard plastics is effectively limited by virtue of cutting and cooling in the cavity, the durability of the finished product is greatly improved, and a degumming phenomenon is avoided in a high-strength experiment.
Description
Technical field
The present invention relates to a kind of Design of Dies, particularly relate to the injection forming mold of the high close-fitting in a kind of automobile shock sheet sealing position.
Background technology
Automobile shock sheet is a kind of accessory conventional in automobile engine assembling, this automobile shock sheet inner core is the circular ironware of axial zone mesopore, coated hard plastic outside ironware, the hard plastic surface of automobile shock sheet side is the stepped anchor ring that ecto-entad side deepens gradually, and the hard plastic surface of opposite side is the excessive curved anchor ring of ecto-entad effluent line style and hard plastic is coated to middle bore edges.
This kind of accessory is after traditional injection moulding processing, due to the chance cold events of plastic material, usually run into the defect of plastic material coated prod tightness deficiency, just middle circular ironware can be there is in the near future and get loose in use, not only under strenuous vibration, lose shock-absorbing function, increase the audible noise vibrated and produce on the contrary.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the injection forming mold proposing a kind of automobile shock sheet, solve the problem of automobile shock sheet sealing position close-fitting.
Object of the present invention will be achieved by the following technical programs: a kind of injection forming mold of automobile shock sheet, described automobile shock sheet inner core is the circular ironware of axial zone mesopore, coated hard plastic outside ironware, the hard plastic surface of automobile shock sheet side is the stepped anchor ring that ecto-entad side deepens gradually, the hard plastic surface of opposite side is the excessive curved anchor ring of ecto-entad effluent line style and hard plastic is coated to middle bore edges, it is characterized in that: described injection forming mold is by patrix, counterdie and blanking pincers are formed, wherein counterdie is provided with the die bed chamber of corresponding stepped anchor ring and the microscope carrier of corresponding circular ironware, patrix is provided with the top die cavity of corresponding curved anchor ring and blanking pincers to be located in patrix just to microscope carrier and and automobile shock sheet central coaxial.
Further, described blanking pincers end is provided with the annular edge of a knife, and blanking pincers bottom is equipped with ram driving mechanism and the stamping press provided meets the not shaping described hard plastic of cut-out.
Further, described blanking pincers are provided with back-moving spring, and reset described blanking pincers after stamping press stripping.
Further, the die bed chamber of a corresponding automobile shock sheet is defined as a cave, and described injection mold is provided with eight caves.
Apply injection forming mold of the present invention, by the blank cooling in die cavity, effectively limit the shrinkage phenomenon of coated hard plastic, finished product durability significantly promotes, and degumming phenomenon does not occur through high strength experiment.

Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
The present invention's innovation proposes a kind of injection forming mold of automobile shock sheet, solves the problem of automobile shock sheet sealing position close-fitting, conscientiously avoids degumming phenomenon, ensures vibration damping sheet effective damping and do not occur to increase and shake in permanent use procedure.As previously mentioned, this automobile shock sheet inner core is the circular ironware of axial zone mesopore, coated hard plastic outside ironware, the hard plastic surface of automobile shock sheet side is the stepped anchor ring that ecto-entad side deepens gradually, and the hard plastic surface of opposite side is the excessive curved anchor ring of ecto-entad effluent line style and hard plastic is coated to middle bore edges.
Product structure characteristic by analysis, before carrying out this injection mo(u)lding, need be assembled to ironware in corresponding die cavity, then implement injection moulding.And due to the demand of sealing position, as shown in Figure 1 to Figure 3, the injection forming mold of this kind of automobile shock sheet clamps 12 by patrix 1, counterdie 2 and blanking and forms, wherein counterdie 2 is provided with the die bed chamber 21 of corresponding stepped anchor ring and the microscope carrier 22 of corresponding circular ironware, and patrix is provided with the top die cavity 11 of corresponding curved anchor ring and blanking pincers 12 to be located in patrix 1 just to microscope carrier 22 and and automobile shock sheet central coaxial.
More specifically, this blanking pincers 12, end is provided with the annular edge of a knife, and blanking is equipped with ram driving mechanism 13 bottom clamping 12 and the stamping press provided meets the not shaping hard plastic of cut-out.And this blanking pincers 12 are provided with back-moving spring 14, reset blanking pincers after stamping press stripping.This Sheet Metal Forming Technology process is carried out in a product injection moulding encapsulate cycle, ram driving mechanism and back-moving spring provide blanking and clamp two contrary active forces, and the active force that this comparatively cushions, before product cooling and shaping prerequisite, ring cutting partition is carried out to product sealing position, improve the sealing position close-fitting before product depanning thus.
Further, the die bed chamber of a corresponding automobile shock sheet is defined as a cave, and injection mold is provided with eight caves, improves production efficiency.
Apply injection forming mold of the present invention, by the blank cooling in die cavity, effectively limit the shrinkage phenomenon of coated hard plastic, finished product durability significantly promotes, and degumming phenomenon does not occur through high strength experiment.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
