Abstract
The utility model discloses a kind of injection forming mold of automobile shock sheet, 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.Especially, this injection forming mold is clamped by upper die and lower die and blanking and forms, wherein counterdie is provided with the die bed chamber of corresponding stepped anchor ring and the microscope carrier of corresponding circular ironware, and 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.Apply injection forming mold of the present utility model, 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.
Description
Technical field
The utility model relates to a kind of Design of Dies, particularly relates 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.
Utility model content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is the injection forming mold proposing a kind of automobile shock sheet, solves the problem of automobile shock sheet sealing position close-fitting.
The purpose of this utility model 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 forming mold is provided with eight caves.
Apply injection forming mold of the present utility model, 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.

Fig. 2 is the lower die structure schematic diagram of the utility model injection forming mold.
Fig. 3 is the structure cut-away view of the utility model injection forming mold matched moulds state.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
The utility model 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 forming mold is provided with eight caves, improves production efficiency.
Apply injection forming mold of the present utility model, 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 utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
