Abstract
The invention discloses a foamed plastic clearance molding mechanism. A cam is driven to rotate by a driving device, so that a flange of the cam jacks a pressing pin, and a pressing rod provided with the pressing pin slides vertically in a cavity; because a rotation shaft of the cam passes through a groove hole in the pressing rod, the pressing rod cannot interfere with the cam when the pressing rod is in the up-down motion; moreover, because a lower straight cavity is internally provided with a punch in a sliding mode, when the pressing rod moves downward, the bottom of the pressing rod hits the punch by virtue of the gravity action of the pressing rod, and the punch is separated away from the inside of the lower straight cavity under the effect of the pressing rod, and is hit into foamed plastic below the lower straight cavity so as to form a clearance. In the subsequent processing course, a clearance is formed in the foamed plastic permanently so as to meet the requirements for processing and using.
Description
Technical field
The present invention relates to a kind of plastic processing device, be specifically related to a kind of foamed plastics gap former structure.
Background technology
Foamed plastic, foaming.Foaming is the process making plastics produce microcellular structure.Nearly all thermosetting and thermoplastic can make foamed plastics, and conventional resin has polystyrene, polyurethane, polyvinyl chloride, polyethylene, ureaformaldehyde, phenolic aldehyde etc.Foamed plastic has the less resin of monomer volume internal consumption, low thermal conductivity, and the mechanical performance of improvement and sound insulation value, add the advantages such as bending Zhang Du.Be widely used among every field.In foamed plastic, have many holes, but these holes are irregular often, when needing well-regulated gap in production and processing, are difficult to directly obtain, need to carry out secondary operations.
Summary of the invention
The object of the present invention is to provide a kind of foamed plastics gap former structure, adopt easy structural design, the object of production and processing can be reached.
For achieving the above object, technical scheme of the present invention is: foamed plastics gap former structure, comprise base, described base is provided with a vertical cavity, described cavity comprises the lower straight chamber set gradually from bottom to up, circular cavity and upper straight chamber, and sliding in described lower straight chamber is provided with a drift, be provided with a depression bar in described circular cavity and upper straight chamber, the middle part of described depression bar is provided with a pad; Be provided with a cam in described circular cavity, the flange of described cam contacts with pad, and the below that described depression bar stage casing is positioned at pad offers slotted eye, and the rotating shaft of described cam is through slotted eye.
When adopting technique scheme, rotated by drive unit driving cam, make the flange jacking pad of cam, the depression bar being provided with pad is vertically slided in the cavities.Rotating shaft due to cam have passed through the slotted eye on depression bar, therefore, in depression bar moves up and down, can not interfere with cam.Moreover arrange a drift owing to sliding in lower straight chamber, when depression bar moves downward, rely on the Action of Gravity Field of self, bottom impact, on drift, makes drift depart from lower straight chamber under the effect of depression bar, squeezes in the foamed plastics of below, forms gap.In following process, forever will form gap at foamed plastics, the requirement reaching processing and use.
Further, the top in described straight chamber is provided with chute, and the top of described depression bar is provided with slide bar, and described slide bar inserts in chute, and described slide bar is arranged with stage clip.This setting can increase the active force of depression bar to drift by stage clip, can alleviate the weight of depression bar like this, saves material.
Further, described pad is hinged with roller, the Hp contacts of described roller and cam.Sliding friction can be become rolling friction by roller by this setting, reduces and damages.
Further, the below described base being positioned at drift is provided with punch holder.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of foamed plastics gap former structure embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, foamed plastics gap former structure of the present invention, comprise base 1, base 1 is provided with a vertical cavity, described cavity comprises the lower straight chamber 2 set gradually from bottom to up, circular cavity 3 and upper straight chamber 4, slide in lower straight chamber 2 and be provided with a drift 5, below base being positioned at drift is provided with punch holder.Be provided with a depression bar 6 in circular cavity 3 and upper straight chamber 4, the middle part of depression bar 6 is provided with a pad; Pad is hinged with roller 61, in circular cavity 3, is provided with a cam 7, the Hp contacts of roller 61 and cam 7.Sliding friction can be become rolling friction by roller 61 by this setting, reduces and damages.The below that the stage casing of depression bar 6 is positioned at pad offers slotted eye, and the rotating shaft of cam 7 is through slotted eye.The top in upper straight chamber 4 is provided with chute, and the top of depression bar 6 is provided with slide bar, and slide bar inserts in chute, slide bar is arranged with stage clip 8.This setting can increase the active force of depression bar 6 pairs of drifts 5 by stage clip 8, can alleviate the weight of depression bar 6 like this, saves material.
In the present invention, rotated by drive unit driving cam 7, make the flange jacking pad of cam 7, the depression bar 6 being provided with pad is vertically slided in the cavities.Rotating shaft due to cam 7 have passed through the slotted eye on depression bar 6, therefore, in depression bar 6 moves up and down, can not interfere with cam 7.Moreover, owing to sliding in lower straight chamber 2, a drift 5 is set, when depression bar 6 moves downward, rely on the gravity of self and the effect of stage clip 8, bottom impact, on drift 5, makes drift 5 depart from lower straight chamber 2 under the effect of depression bar 6, squeeze in the foamed plastics of below, form gap.In following process, forever will form gap at foamed plastics, the requirement reaching processing and use.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
