Description
Technical field
The present invention relates to technical field of mold, more particularly to a kind of circular product note with push-down sliding block demolding structure
Mould.
Background technology
For some circular products, due to its small volume, and border has annular back-off, it is necessary to compared with multi-slide to splice
Into the product of circle.It is stripped after injection molding, it is necessary to be realized by sliding block.Traditional sliding block demoulding is to lean on Angle Pin core_pulling demoulding
To complete the demoulding of the back-off of product.This mode has the disadvantages that：First, sliding block is more, each bad fixation of sliding block；Second,
Sliding block volume is larger；Third, the motion that each sliding block can not be simultaneously consistent during motion, damages sliding block.Traditional sliding block demoulding
The die sinking distance that mode makes mould actual is big, and sliding block volume is big, and not only wasting space increased processing cost again, demoulding difficulty, and not
It is easy-maintaining.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of circle with push-down sliding block demolding structure
Shape injection mould of products, being synchronized with the movement for all sliding blocks can be ensured in die sinking, stripping action is more reliable and more stable.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：One kind tool
There are the circular product injection mold of push-down sliding block demolding structure, including preceding mould and rear mold, the preceding mould includes panel, is vertically arranged
Two preceding support blocks on rear side of the panel and the front template being horizontally placed on two preceding support blocks, the rear mold include bottom plate, vertical
Support block and the rear pattern plate after two on support block is horizontally placed on after two be arranged on front side of bottom plate, is set between two preceding support blocks
There is a preceding mould top plate, be provided with rear mold top plate between support block after two, front cavity component is provided with the front template, is provided with rear pattern plate
Rear cavity component, front cavity component are provided with circular preceding die cavity, are evenly distributed with outside the excircle of the preceding die cavity multiple with before
The slide block chamber of mould cavity, is respectively equipped with a sliding block in each slide block chamber, preceding die cavity, multiple sliding blocks on front cavity component and
The injection die cavities for being molded circular product are cooperatively formed between rear cavity component, wherein, the end of multiple sliding blocks is spliced to form
The circular cavity wall of injection die cavities, the preceding mould top plate are provided with multiple one-to-one push rods in position with multiple sliding blocks respectively,
Push rod can act on sliding block, and the side of the remote preceding die cavity of sliding block is inclined-plane, and slide block chamber also has to match with the inclined-plane of sliding block
The inclined-plane cavity wall of conjunction.
Further, the preceding mould guide pillar of preceding mould top plate is provided through on the panel, rear mold is provided through on the bottom plate
The rear mold guide pillar of top plate.
Further, the front cavity component include the first front cavity and on rear side of the first front cavity second before mould
Benevolence, the rear cavity component include rear mold mold insert, the first rear cavity and the second rear cavity on front side of the first rear cavity, after this
Mould mold insert is arranged in the first rear cavity and the second rear cavity, and before the anterior insertion of rear mold mold insert in die cavity.
The beneficial effects of the invention are as follows：The front cavity component of the present invention is provided with preceding die cavity, equal outside the excircle of preceding die cavity
It is even to be provided with multiple slide block chambers, sliding block is provided with slide block chamber, the end of multiple sliding blocks is spliced into circle, is fixed with preceding mould top plate
With the push rod of the position correspondence of sliding block, push rod can act on sliding block, and in die sinking, top plate can drive all push rods to eject,
All sliding blocks synchronously eject in the presence of push rod, because sliding block and slide block chamber have the inclined-plane to cooperate, so as to sliding
Block can be radially away from injection die cavities movement again during ejecting backward, so as to realize the disengaging of sliding block and product,
Complete the demoulding of product back-off.Sliding block small volume in the present invention, demolding structure is simple, reduces mould processing cost, whole mould
Have stable, sliding block can be synchronized with the movement, and de-molding position is accurate, improve product quality.
