Description

Injection plastic package material bubble blowing forming die

Technical Field

The utility model belongs to the field of injection packaging equipment, and particularly relates to an injection plastic package material foam blowing forming die.

Background

Blister packages, also known as blister packages, of pharmaceutical products are one of the main forms of pharmaceutical product packaging, and have been previously used for the mechanized packaging of solid pharmaceutical products such as tablets, capsules, suppositories, pills, and the like. The medicine bubble cap package is formed by filling medicine into bubble caps formed by vacuum plastic or compression molding, using covering materials such as aluminum foil, paper film and the like, and sealing with a bubble forming base material in a heat sealing way under certain temperature and time conditions by pressing or bonding.

The flat plate type bubble cap package is one of bubble cap packages, and the process flow comprises the following steps: the method comprises the steps of heating a formed plastic sheet to a softened state at a flat plate type preheating device, conveying the plastic sheet to a flat plate type forming device by traction of a stepping device, blowing the softened plastic sheet into a bubble cap by using compressed air, filling a packaged object into the bubble cap by a filling device, conveying the packaged object to a flat plate type sealing device, sealing a bubble cap plate and a covering material at proper temperature and pressure, and finally conveying the bubble cap plate and the covering material to a typing, embossing and punching device.

There are few flat blister packages currently used in the packaging of injectables, and existing molds have one or more bumps at the edges during blow molding to form bumps on the edges of the blister sheet in order to facilitate tearing of the lidding material during use. However, in actual production, after the bubble plate is sealed with the covering material, the covering material still adheres to the edges and the salient points of the bubble plate, so that the covering material is still difficult to tear during use, and users have more complaints.

Disclosure of Invention

The utility model aims to provide a foam blowing forming die for an injection plastic packaging material on the basis of the prior art.

The technical scheme of the utility model is as follows:

the injection molding material blowing forming mold includes one upper mold for blow molding bubble plate and one lower mold for forming bubble plate, one mold set capable of forming one bubble plate or several mold sets capable of forming several bubble plates, one blowing slot for forming injection packing space in the mold set of the lower mold, one long strip of 0.5-4 mm x 5-10 mm in the corner or the edge of the mold set of the lower mold, and one notch around the long strip and not communicated with the blowing slot.

In one embodiment, the length is 1-3 mm by 5-10 mm.

In one version, the strips are 2mm by 7mm in size.

In one embodiment, the shape of the concave groove is selected from one of triangle, semicircle, quadrangle, polygon with more than 4 sides, circle, ellipse, arc, flower, ring, triangle with one or more angles being arc, quadrangle with one or more angles being arc.

In one aspect, the shape of the concave groove is selected from one of a triangle, a semicircle, a quadrilateral, an arc, one or more triangles with angles of arc, one or more quadrilaterals with angles of arc.

In one aspect, the shape of the concave trough is selected from one of a triangle, one or more triangles with an arc.

In one scheme, a compressed air outlet is arranged on the upper molding die.

In one embodiment, the module is rectangular, and the strip and the recess are formed at one corner of the rectangular module.

The utility model has the beneficial effects that:

the plastic package material foam molding die provided by the utility model can be applied to a flat plate type blister package of injection, and forms an easy-tearing opening at the corner or the edge protruding part of a blister plate through the strip and the concave groove. The die can reduce bump adhesive caused by extrusion in the process of sealing the bubble cover plate and the covering material at the rear part during use, and reduces customer complaints by facilitating tearing through the easy-to-tear opening, thereby providing a better product.
