Abstract
The utility model discloses an one shot forming fretwork plastics chair mould, comprises an upper die and a lower die, last mould in be equipped with the die cavity, the lower mould in be equipped with core, its characterized in that the die cavity in whole the distribution have the fretwork groove, the core on be provided with with the arch that corresponds of fretwork groove to, the sprue gate sets up the center that is located seat support and back of the chair juncture in the die cavity. The utility model discloses an one shot forming fretwork plastics chair mould because whole the distribution has the fretwork groove in the die cavity, be provided with on the core with the arch that corresponds of fretwork groove, go up the lower mould compound die after, core and die cavity cooperation form network structure in the space between the two, therefore can pour into a mould out the chair body of whole fretwork. And because the sprue gate sets up the center that lies in seat support and back of the chair juncture in the die cavity, the plastic is followed the centre and is radial outflow, can arrive each pouring position, accomplish the one pouring shaping.
Description
Technical field
This utility model relates to mould of plastics field, particularly relates to the mould applications of plastic chair body, specifically a kind of one-shot forming hollow out plastic chair mould.
Background technology
Existing injection mold, including upper mould (also referred to as master mold or die) and counterdie (also referred to as male model or punch), is provided with die cavity, is provided with core in described counterdie in described upper mould.After upper and lower mould matched moulds, core coordinates with die cavity, is injected into plastic cement in space between.Die sinking after plastic cement cooling, by taking out plastic after the ejecting mechanism demoulding.In general, vestige can be left in the sprue gate of plastic, therefore generally designs sprue gate in the position not easily observed, such as the back side of seat support.But, for the chair body of seat support and chair back entirety hollow out, owing to plastic cement glide path is pipe net distribution, if sprue gate being arranged on the back side of seat support, then plastic cement likely just solidifies before not arriving far-end, to such an extent as to cannot realize once integrated poured.
Summary of the invention
The problem of the above-mentioned demoulding difficulty being prior art existence to be solved in the utility model, it is desirable to provide a kind of in-mould decoration mould suitable in hollow out chair body.
For solving the problems referred to above, this utility model is by the following technical solutions: one-shot forming hollow out plastic chair mould, including upper die and lower die, it is provided with die cavity in described upper mould, it is provided with core in described counterdie, it is characterised in that in described die cavity, overall distribution has hollow slots, described core is provided with the projection corresponding with described hollow slots, further, sprue gate is arranged in die cavity and is positioned at seat support and the center of chair back intersection.
One-shot forming hollow out plastic chair mould of the present utility model, owing in die cavity, overall distribution has hollow slots, core is provided with the projection corresponding with described hollow slots, after upper and lower mould matched moulds, core coordinates with die cavity, form network structure in space between, thus pourable go out overall hollow out chair body.Further, being positioned at seat support and the center of chair back intersection owing to sprue gate is arranged in die cavity, plastic cement flows out radially from centre, it is possible to arrives each cast position, completes one-time cast-forming.
Adopt the chair body of die casting of the present utility model, have the following characteristics that
1, due to chair body entirety hollow out, outward appearance is pure and fresh attractive in appearance, and moulding is unique.
2, quantity of plastics can be greatly saved, reduce product cost.
3, product weight is light, it is easy to transport and use.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of mould on this utility model.
Fig. 2 is the structural representation of this utility model counterdie.
Fig. 3 is the structural representation of the hollow out chair adopting this utility model cast.
Detailed description of the invention
See figures.1.and.2, one-shot forming hollow out plastic chair mould of the present utility model, including upper mould 1 and counterdie 2, it is provided with die cavity in described upper mould, being provided with core in described counterdie, in described die cavity, overall distribution has hollow slots 3, and described core is provided with the projection 5 corresponding with described hollow slots, further, sprue gate 4 is arranged in die cavity and is positioned at seat support and the center of chair back intersection.
With reference to Fig. 3, a kind of hollow out chair, including chair body 6 and chair foot 7.It is overall structure that described chair body 6 includes the chair back 8 and seat support 9, the chair back 8 and seat support 9, by mould one-time cast-forming of the present utility model.
One-shot forming hollow out plastic chair mould of the present utility model, owing in die cavity, overall distribution has hollow slots 3, core is provided with the projection 5 corresponding with described hollow slots, after upper and lower mould matched moulds, core coordinates with die cavity, form network structure in space between, thus pourable go out overall hollow out chair body.Further, being positioned at seat support and the center of chair back intersection owing to sprue gate 4 is arranged in die cavity, plastic cement flows out radially from centre, it is possible to arrives each cast position, completes one-time cast-forming.
Adopt the chair body of die casting of the present utility model, have the following characteristics that
1, due to chair body entirety hollow out, outward appearance is pure and fresh attractive in appearance, and moulding is unique.
2, quantity of plastics can be greatly saved, reduce product cost.
3, product weight is light, it is easy to transport and use.
It is understood that above-described embodiment is simply to explanation of the present utility model, rather than to restriction of the present utility model, any without departing from the utility model creation in this utility model spirit, each fall within protection domain of the present utility model.
