Abstract

The utility model provides a PVC blowing injection die for molding PVC blowing slippers in one step. The PVC blowing injection die comprises an upper die, a lower die and a die core positioned between the upper die and the lower die, a side edge of the die core is hinged with the lower die, the upper die is hinged with the identical side edge of the die core, an overturned limit device is arranged between the die core and the lower die, and an overturned limit device is arranged between the upper die and the die core. Because the die core between the upper die and the lower die adopts an overturned structure, a solid molding die cavity used for the one-step molding PVC blowing slippers is formed among the upper die, the lower die and the die core, simultaneously, when in die sinking, the PVC blowing slipper molded on the die core can be overturned with the die core together, and the die demould operation is convenient.

Description

A kind of PVC air blowing injection mold

Technical field

The utility model relates to a kind of mould, particularly a kind of PVC air blowing injection mold that is used for one-shot forming PVC air blowing slippers.

Background technology

Nowadays the pvc air blowing raw material of Cai Yonging has good thermostable effect, can pass through high temperature process smoothly, guarantee to produce the air blowing product that conforms to quality requirements, it has lighter in weight, good, the super skidproof effect of flexibility, tangent plane such as EVA goods, color divergence is even, serial advantage such as surface-brightening, market prospects are wide.The mould of the known PVC of being used for air blowing injection moulding generally comprises upper die and lower die; described upper die and lower die one side is along being hinged; be provided with injection channel and insufflation channel in patrix or the counterdie; this kind mould can only injection moulding PVC air blowing footwear at one time sole or group's face; and sole and group's face that can not disposal molding PVC air blowing footwear, otherwise can't the demoulding.When making toy, also face similar problem simultaneously with PVC air blowing raw material.

The utility model content

The purpose of this utility model is to provide a kind of PVC air blowing injection mold that can disposal molding PVC air blowing slippers.

The technical scheme that the utility model adopted is such: a kind of PVC air blowing injection mold, comprise upper die and lower die and the core rod between patrix and counterdie, one side of described core rod is along hinged with counterdie, the same side of described patrix and core rod is along hinged, and be provided with the upset stopping means between described core rod and the counterdie, be provided with the upset stopping means between described patrix and the core rod.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: the core rod between described patrix and the counterdie is arranged to turning structure, so on the one hand, the molding space that can form a solid between upper die and lower die and the core rod is used for one-shot forming PVC air blowing slippers, during die sinking simultaneously, the PVC air blowing slippers that take shape on the core rod can together overturn conveniently stripped together with core rod.

The specific embodiment

Referring to figs. 1 to Fig. 3, embodiment discloses a kind of PVC air blowing injection mold, comprise patrix 1, counterdie 2 and the core rod 3 between patrix 1 and counterdie 2, be provided with injection channel and insufflation channel that PVC blows and expects between the outside of described patrix 1 and its die cavity, in the die cavity that described core rod 3 main parts form between patrix 1 and counterdie 2, one side of core rod 3 is along extending to counterdie 2 outsides and hinged with counterdie 2, be positioned at this articulated position, described patrix 1 is hinged with core rod 3, described core rod 3 is positioned at counterdie 2 hinge portions and is provided with a gag lever post 31 simultaneously, when core rod 3 was turned to certain angle as 60 °, gag lever post 31 was run into the outside of counterdie 2 along also limited; Described patrix 1 is positioned at core rod 3 hinge portions and is provided with a limited block 11, and when patrix 1 is turned to certain angle as 60 ° with respect to core rod 3 (this moment, patrix 1 was with respect to 120 ° of counterdie 2 upsets), described limited block 11 is run into gag lever post 31 tops and limited.In addition, the contact portion between described patrix 1 and the counterdie 2 is positioned at the outside of die cavity along being provided with sealing ring, and above-mentioned sealing ring, injection channel and insufflation channel belong to known mould inherent structure, so do not repeat them here.

Based on technical problem to be solved in the utility model and the technical scheme that adopted, thereby everyly realize the mould of PVC air blowing slippers single injection-molded, all belong to the scope of the utility model institute letter lid by between the patrix of known PVC air blowing mould and counterdie, increasing a hinged each other core rod.

Claims (1)

1, a kind of PVC air blowing injection mold, it is characterized in that: comprise upper die and lower die and the core rod between patrix and counterdie, one side of described core rod is along hinged with counterdie, the same side of described patrix and core rod is along hinged, and be provided with the upset stopping means between described core rod and the counterdie, be provided with the upset stopping means between described patrix and the core rod.
