Abstract
The utility model discloses the injection mold of a kind of pair of back-off plastic parts, comprise front mould, can relative to the rear mold of front mould movement, two oblique tops and core, two oblique top lower end insert type in-cores, during injection moulding, the die cavity of rear mold is stretched in two oblique top lower ends, described front mould is provided with a cylinder and tilted footstock, and cylinder cylinder post is fixedly connected with tilted footstock, and two oblique tops are connected with tilted footstock.Compared with prior art, the complete rear mold of the utility model injection moulding support or oppose from cylinder while the movement of front mould direction also simultaneously Work Promote tilted footstock make two oblique tops also move released by plastic parts to deviating from front mould direction, two oblique tops are also in the process deviating from the movement of front mould direction, distance between two oblique tops diminishes gradually, thus two oblique tops are exited completely from two back-offs of plastic parts, make the smooth demoulding of plastic parts, there is compact conformation, the advantage that simple and cost of manufacture is low.
Description
Technical field
The utility model relates to injection mold technical field, particularly relates to the injection mold of a kind of pair of back-off plastic parts.
Background technology
The injection mold of existing injection moulding belt back-off plastic parts, comprising front mould and can relative to the rear mold of front mould movement, in order to make the demoulding of band back-off plastic parts energy, be add two pieces of ejector retainner plates by front mould to carry out ejection pitched roof, such structure needs to take larger space, and complex structure and cost of manufacture high.
Therefore, design a kind of compact conformation, the injection mold of the injection moulding belt back-off plastic parts that simple and cost of manufacture is low is people's technical issues that need to address.
Utility model content
Main purpose of the present utility model is to provide the injection mold of a kind of compact conformation, the two back-off plastic parts that simple and cost of manufacture is low.
For achieving the above object, the technical scheme that the utility model adopts is: the injection mold of a kind of pair of back-off plastic parts, comprise front mould, can relative to the rear mold of front mould movement, two oblique tops and core, two oblique top lower end insert type in-cores, during injection moulding, the die cavity of rear mold is stretched in two oblique top lower ends, and described front mould is provided with a cylinder and tilted footstock, cylinder cylinder post is fixedly connected with tilted footstock, and two oblique tops are connected with tilted footstock.
Preferably, described two oblique top upper ends are connected with tilted footstock.
Preferably, described tilted footstock is provided with two grooves, and two oblique top upper ends embed in two grooves respectively.
Preferably, described two groove cross section are T-shaped.
Preferably, described two oblique top upper end shapes and two groove cross section shapes similar.
Preferably, described core is provided with the access ramp of accommodation two oblique top.
Preferably, described cylinder and tilted footstock are positioned at outside front mould.
Compared with prior art, the utility model is provided with a cylinder and tilted footstock by being provided with rear mold in rear mold, cylinder cylinder post is fixedly connected with tilted footstock, two oblique tops are connected with tilted footstock, the complete rear mold of injection moulding support or oppose from cylinder while the movement of front mould direction also simultaneously Work Promote tilted footstock make two oblique tops also move released by plastic parts to deviating from front mould direction, two oblique tops are also in the process deviating from the movement of front mould direction, distance between two oblique tops diminishes gradually, thus two oblique tops are exited completely from two back-offs of plastic parts, make the smooth demoulding of plastic parts, there is compact conformation, the advantage simple and cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the injection mold of the utility model a kind of pair of back-off plastic parts;
Fig. 2 is the stereogram after the injection mold of the utility model a kind of pair of back-off plastic parts removes front mould and rear mold;
The realization of the utility model object, functional characteristics and advantage will in conjunction with the embodiments, are described further with reference to accompanying drawing.
Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, the utility model provides the injection mold of a kind of pair of back-off plastic parts, comprise front mould 1, can relative to rear mold 2, two oblique top 3 of front mould movement and core 4, access ramp 41, two oblique top 3 lower end that core 4 is provided with accommodation two oblique top 3 is inserted in the access ramp 41 of core 4, during injection moulding, the die cavity of rear mold 2 is stretched in two oblique top 3 lower ends, be provided with a cylinder 5 and tilted footstock 6 outside front mould 1, the cylinder post of cylinder 5 is fixedly connected with tilted footstock 6, and two oblique top 3 upper ends are connected with tilted footstock 6.
Tilted footstock 6 is provided with two groove 61, two oblique top 3 upper ends and embeds in two grooves 61 respectively; Two groove 61 cross sections are T-shaped, two oblique top 3 upper end shapes and two groove 61 shape of cross sections similar.Only two oblique top 3 upper ends need be embedded in two grooves 61 of tilted footstock 6 during installation, there is the advantage that structure is simple and easy for installation.
The injection mold operation principle of the utility model a kind of pair of back-off plastic parts is as follows: the complete rear mold 2 of injection moulding to cylinder 5 while deviating from front mould 1 direction movement also simultaneously Work Promote tilted footstock 6 make two oblique tops 3 also move released by plastic parts 7 to deviating from front mould 1 direction, two oblique tops 3 also move to deviating from front mould 1 direction, distance in moving process between two oblique tops 3 diminishes gradually, thus two oblique tops 3 are exited completely from two back-offs of plastic parts 7, make plastic cement 7 smooth demouldings, there is compact conformation, the advantage that simple and cost of manufacture is low.
These are only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
