Description
Technical field
The utility model relates to mould applications, and in particular to a kind of Slide mechanism of double-shot moulding mould.
Background technique
Injection mold is a kind of tool for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Tool.Injection molding is a kind of processing method used when producing certain complex-shaped components in batches.It refers specifically to melt heated
Plastics obtain formed products after cooling and solidifying by injection molding machine high pressure injection type chamber.And Slide mechanism be injection mold in can
Side core-pulling or undercut and homing action are obtained to haul out product back-off, the sunken mechanism for waiting positions.
Slide mechanism frequently includes line position seat and is installed on the slide insert of line position seat, during mold clamping, line position
Seat is gradually mobile to type chamber under the guidance of guide post, until the front end insert type chamber of slide insert, then starts to be molded, is molded
After the completion, mold divides in mold process, and inclined guide pillar guidance line position seat is gradually distance from type chamber, and slide insert is made to be detached from the production that injection molding is completed
Product.
And when being molded the double-colored product of side core-pulling, die combination passes through double-shot moulding before generally requiring single rear mold and two sets
Machine is molded, and first carries out mold-closing injection by rear mold and preceding mould one, and slide insert insert type chamber while molding is completed wait be molded
Divide slide insert after mould to exit from type chamber, is rotated rear mold as the corresponding position of preceding mould two by the turntable of double coloured plastic injection machine, then
Secondary slide insert when being molded can again insertable into type chamber, be easy to appear at this time slide insert shunk because product is micro, position it is inclined
The reasons such as shifting cause the slotting wound to the first color product, and then influence the fitted position of product and influence real work performance, to keep away
The occurrence of exempting from such can only improve the accuracy of manufacture and technique requirement, and then greatly increase production cost, even so good
Product rate is still extremely limited.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind be effectively improved slotting condition of the injury condition,
