Description

A kind of pitched roof mechanism in automobile headlamp shade shaping mould
Technical field
The utility model relates to injection mold fields, more particularly, to the oblique top machine in a kind of automobile headlamp shade shaping mould Structure.
Background technique
Injection molding is a kind of processing method used when producing certain complex-shaped components in batches.It refers specifically to be heated and melt The material of change injects die cavity and obtains molded product after cooling and solidifying.Injection mold is a kind of tool for producing plasthetics;? It is to confer to the tool of plasthetics complete structure and accurate dimension.Injection mold is generally made of dynamic model and cover half two parts, is moved Mould is mounted on the moving die plate of injection (mo(u)lding) machine, and cover half is mounted on the fixed form of injection (mo(u)lding) machine.In injection moulding Dynamic model and cover half closure constitute running gate system and type chamber, and dynamic model and cover half separation are to take out plastic products when die sinking.
Although the structure of mold is according to the type of plastics variety and performance, the shape of plastic products and structure and injector It is ever-changing Deng different, but basic structure is consistent, i.e., mainly by running gate system, forming part, exhaust system, temperature control System and ejection system composition.Wherein running gate system and forming part be with the direct contact portion of plastics, and with plastics and product And change, it is most complicated in mold, variation maximum, it is desirable that processing finish and the highest part of precision;Running gate system refers to modeling Expect runner section, including sprue, cold slug well, runner and cast gate before entering type chamber from nozzle etc..Forming part refers to structure At the various parts of article shape, including dynamic model, cover half and type chamber, type core, curved lever and exhaust outlet etc..
Automobile headlamp shade is generally plastic part, and is manufactured by mold injection.It is existing to be used for formed automobile front lamp cover Injection mold in, due to automobile headlamp shade be irregular shape plastic part, the knot of the mode for injection molded automobile front lamp cover The complexity that structure also becomes, and after automobile headlamp shade in irregular shape molding, how smoothly demoulding is mold from mold Designer has to solve the problems, such as.It is as shown in Figure 1 a automobile headlamp cover structure, mold design personnel are in design mold During, a pitched roof mechanism is devised, lampshade after molding is enable to eject upwards, so that clamp device can smoothly take Product out.
Summary of the invention
The technical problem to be solved by the utility model is to provide the pitched roof mechanisms in a kind of automobile headlamp shade shaping mould, are intended to Lampshade after molding is set to eject upwards by the pitched roof mechanism, so that clamp device can smoothly take out lampshade.
Technical solution adopted by the utility model to solve the above technical problems is as follows: in a kind of automobile headlamp shade shaping mould Pitched roof mechanism, including jacking block, the first mandril, the second mandril, and the mode block being consistent with product profile, the mode block packet The first shaped insert, the second shaped insert are included, first shaped insert is stitched together with the second shaped insert, described The tail portion of second shaped insert is in a tapered horn, and the jacking block is equipped in the recess of cone angle and the tail portion with the second shaped insert It is adapted, the recess on the jacking block is against on the tail portion of the second shaped insert, and first mandril is erected at the first one-tenth Between type insert and the second shaped insert, the second mandril inclination is built up in the second shaped insert, second top Bar one end is fixed on jacking block, and the other end of second mandril is resisted against the side of the first mandril, first mandril Top be equipped with retention bead, outer on second mandril to be cased with spring, second mandril is resisted against on the first mandril One end can be slided upwards to retention bead along the side of the first mandril, first mandril can eject upwards first at Type insert, the jacking block can eject the second shaped insert upwards, and second mandril and the second shaped insert link.
Compared with prior art, it is simple that the utility model has the advantage of structures, design rationally, can by lampshade smoothly from It is demoulded in mold, in simple terms, increases the pitched roof mechanism in a mold, jacking block is connect by thimble with the top plate in mold, is pushed up Plate jacks up jacking block upwards, and jacking block ejects the second shaped insert, and the second shaped insert is moved upwards with the second mandril, the second top Bar is slided to retention bead upwards along the side of the first mandril, and then the first mandril is under the action of the second mandril, upwards The first shaped insert is ejected, removes lampshade from the first shaped insert, the second shaped insert finally by clamp device.
Detailed description of the invention
Fig. 1 is front lamp cover structural schematic diagram;
Fig. 2 is the utility model part-structure decomposition diagram.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this Utility model is not used to limit the utility model.
It is as shown in Figure 1 to Figure 2: the pitched roof mechanism in a kind of automobile headlamp shade shaping mould, including jacking block 1, the first mandril 2, Second mandril 4, and the mode block 3 being consistent with product profile, mode block 3 include the first shaped insert 31, the second shaped insert 32, the first shaped insert 31 is stitched together with the second shaped insert 32, and the tail portion of the second shaped insert 32 is in a tapered horn, jacking block 1 is equipped in the recess 12 of cone angle and is adapted with the tail portion of the second shaped insert 32, and the recess 12 on jacking block 1 is against the second one-tenth On the tail portion of type insert 32, the first mandril 2 is erected between the first shaped insert 31 and the second shaped insert 32, the second mandril 4 Inclination is built up in the second shaped insert 32, and 4 one end of the second mandril is fixed on jacking block 1, and the other end of the second mandril 4 is resisted against The side of first mandril 2, the top of the first mandril 2 are equipped with retention bead 21, are cased with spring 5, the second mandril outside on the second mandril 4 4 one end being resisted against on the first mandril 2 can slide upwards along the side of the first mandril 2 to retention bead 21, the first mandril 2 The first shaped insert 31 can be ejected upwards, and jacking block 1 can eject the second shaped insert 32 upwards, and the second mandril 4 and the second molding are inlayed Block 32 links.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
