Abstract
A kind of back-off structure injection mold, is related to technical field of mechanical processing, and the solution is to reduce back-off structure injecting products production cost.The mold includes cover half core, moving-mould-core, the cover half type of the cover half core is intracavitary to be fixed with oblique guide block, and the cover half type of cover half core it is intracavitary be equipped with can be along the slide block insert of cover half core radially slided, the guiding skewed slot tilted down from outside to inside along the radial direction of cover half core is formed on the oblique guide block, the upper end of slide block insert is formed with card slot；The moving-mould-core is equipped with can be along the side slide of moving-mould-core radially slided, guide rib and clamp are formed on the side slide, guide rib on side slide is caught in the guiding skewed slot of oblique guide block with gap fiting mode, clamp on side slide is caught in the card slot of slide block insert upper end, enables slide block insert with side slide synchronous slide.Mold provided by the utility model is suitable for back-off structure injecting products.
Description
Technical field
The utility model relates to mechanical manufacturing technologies, more particularly to a kind of technology of back-off structure injection mold.
Background technique
Existing injection mold cannot achieve the depanning of back-off structure, therefore for some notes for requiring back-off structure
Molding product can only realize which results in the production costs of the injecting products with back-off structure using the combination of multiple injecting products
Rise.
Utility model content
For above-mentioned defect existing in the prior art, the technical problem to be solved by the utility model is to provide a kind of energy
The depanning of back-off structure injecting products is realized, so as to reduce the back-off structure injection mould of back-off structure injecting products production cost
Tool.
In order to solve the above-mentioned technical problem, a kind of back-off structure injection mold provided by the utility model, including cover half
Core, moving-mould-core are formed on the cover half core and determine model cavity, and the hot flow path of model cavity is determined in connection, is formed on the moving-mould-core
There is movable model chamber, cover half core is located at the surface of moving-mould-core, and cover half core is docked with moving-mould-core with movable fit system, cover half
Movable model chamber one shaping mold cavity of composition for determining model cavity and moving-mould-core of core, it is characterised in that:
The cover half type of the cover half core is intracavitary to be fixed with oblique guide block, and can control in intracavitary be equipped with of the cover half type of cover half core
The slide block insert of sliding is formed with the guiding skewed slot tilted down from left to right, the upper end shape of slide block insert on the oblique guide block
At there is card slot；
It is fixed with guide pin on the moving-mould-core, and is equipped with the side slide that can be horizontally slipped, cover half core on moving-mould-core
Cover half type top of chamber offer pin hole, the upper end of the guide pin is with the pin of movable fit system insertion cover half type top of chamber
Hole；
Guide rib and clamp are formed on the side slide, the guide rib on side slide is caught in gap fiting mode
The guiding skewed slot of oblique guide block, the clamp on side slide are caught in the card slot of slide block insert upper end, enable slide block insert with side slide
Synchronous horizontally slips.
Back-off structure injection mold provided by the utility model, the back-off structure of injecting products is realized using slide block insert
The molding at position, and push slide block insert to be detached from product using side slide after injecting products molding, so that having back-off structure
Injecting products can smooth depanning, back-off structure injecting products production cost can be reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the back-off structure injection mold of the utility model embodiment.
Specific embodiment
The embodiments of the present invention are described in further detail below in conjunction with Detailed description of the invention, but the present embodiment and are not had to
In limitation the utility model, all similar structures and its similar variation using the utility model should all be included in the utility model
Protection scope, the pause mark in the utility model indicates the relationship of sum.
As shown in Figure 1, a kind of back-off structure injection mold provided by the utility model embodiment, including it is cover half core 1, dynamic
Mold core 2 is formed on the cover half core 1 and determines model cavity, and the hot flow path 7 of model cavity is determined in connection, is formed on the moving-mould-core 2
Movable model chamber, cover half core 1 is located at the surface of moving-mould-core 2, and cover half core 1 is docked with moving-mould-core 2 with movable fit system, fixed
Movable model chamber one shaping mold cavity of composition for determining model cavity and moving-mould-core 2 of mold core 1, it is characterised in that:
The cover half type of the cover half core 1 is intracavitary to be fixed with oblique guide block 3, and intracavitary equipped with energy in the cover half type of cover half core 1
Along the slide block insert 5 of cover half core radially slided, the radial direction being formed on the oblique guide block 3 along cover half core dips down from outside to inside
Oblique guiding skewed slot, the upper end of slide block insert 5 are formed with card slot；
It is fixed with guide pin 6 on the moving-mould-core 2, and being equipped on moving-mould-core 2 can radially sliding along moving-mould-core
Side slide 4, the cover half type top of chamber of cover half core 1 offer pin hole, and the upper end of the guide pin 6 is fixed with the insertion of movable fit system
Pin hole at the top of model cavity；
Guide rib and clamp are formed on the side slide 4, the guide rib on side slide 4 is with gap fiting mode card
Enter the guiding skewed slot of oblique guide block 3, the clamp on side slide 4 is caught in the card slot of 5 upper end of slide block insert, enable slide block insert 5 with
4 synchronous slide of side slide.
The utility model embodiment is suitble to the injecting products for having back-off structure, realizes injecting products using slide block insert
The molding at back-off structure position, working method are as follows:
Injection molding melt is injected into shaping mold cavity (being constituted by determining model cavity and movable model chamber) by hot flow path, it is molten wait be molded
Liquid is opened after being cooled and shaped, and when die sinking moves down moving-mould-core, so that moving-mould-core is separated with cover half core, under moving-mould-core
It moves, guide pin is deviate from from the pin hole of cover half type top of chamber, under the guiding of guiding skewed slot of the side slide on oblique guide block inwardly
Sliding, so that slide block insert and shaped article are detached from, then can be taken off molding and produce to drive the inside Slideslip of slide block insert
Product.
