Description

Plastic uptake positive and negative pressure mould side frame mechanism

Technical Field

The utility model relates to a positive negative mould side frame mechanism of plastic uptake belongs to plastic uptake mould technical field.

Background

The plastic suction forming die frame in the prior art generally adopts steel plate welding support, and when bearing higher atmospheric pressure, the steel plate junction collapses easily, leads to atmospheric pressure to leak, not only influences product quality, mould, die frame life, still can produce the safety problem.

Disclosure of Invention

The utility model aims to solve the technical problem that a positive negative mould side frame mechanism of plastic uptake that sealing performance is good is provided.

In order to solve the technical problem, the utility model discloses a technical scheme does:

the utility model provides a positive negative pressure mould side frame mechanism of plastic uptake, include by bottom plate, roof, with the four sides downside that the bottom plate is connected and with the four sides epipleural that the roof is connected, be equipped with a plurality of fixed mould fixing pin holes on the bottom plate, the bottom plate and be equipped with the air current inlet hole on the roof respectively, and be equipped with the pterygoid lamina on its relative both sides, the four sides between the downside and with connect between the bottom plate and adopt protruding and the groove connection who corresponds on the relative limit, outside adoption fix with screw, the four sides between the epipleural and with connect between the roof and adopt protruding and the groove connection that corresponds on the relative limit, outside adoption fix with screw, the four sides downside and four sides adopt protruding and groove connection between the epipleural.

Furthermore, all the bulges and the grooves are positioned in the middle of the opposite connecting edge.

Furthermore, the four sides lower side plate and the four sides upper side plate are connected with each other and comprise side edge convex grooves and top edge convex grooves.

Furthermore, the size of the bulge between the four lower side plates and the four upper side plates is slightly smaller than the groove.

Furthermore, the bulges and the grooves at the turning positions of the top edges between the lower side plate and the upper side plate on the four sides are in arc transition.

Furthermore, at least one group of opposite inner walls of the lower side plate is provided with a limit groove.

The utility model discloses the beneficial effect who reaches: this device adopts the connection setting of unsmooth clamp connection, can show improvement sealing performance, through the position setting to protruding recess, makes all junctions of framed, cross can both realize good sealedly, prevents effectively that malleation air compressor machine air supply pressure from getting into the inside hourglass of framework outward, and atmospheric pressure does not leak outward and has effectively guaranteed the shaping stable quality of plastic uptake package goods, improves the life of mould, framed can not explode and operate positive negative pressure plastic uptake equipment personnel's production safety.
