Abstract
The utility model discloses an injection mould for one-step molding a balance tray. The injection mould for one-step molding the balance tray comprises a male mould and a female mould, wherein a feeding trough is arranged in a parting surface of the female mould; the feeding trough is communicated with a feeding hole; the feeding hole penetrates through a mould frame of the female mould; a through hole communicated with the inner end of the feeding trough is formed in the inner wall of the mould cavity of the female mould. The feeding trough does not directly stretch into the mould cavity, and a material is injected into the mould cavity through a through hole, so that after a product is moulded, the product and a material handle (namely, a part moulded at the feeding trough) are not connected together and the product is connected with a residual material at the through hole; however, the through hole is very small, and in the demoulding process, a junction of the product and the residual material at the through hole is cut off by the edge of the through hole, so that when the product is ejected out, a finished product which is not required to be processed any more is obtained, therefore, the labor cost and the rejection rate of the products are reduced; and the injection mould for one-step molding the balance tray belongs to the technical field of moulds.
Description
Technical field
The utility model relates to a kind of mould, relates to or rather a kind of balance on goods and services in-mould decoration mould
Background technology
Product use balance on goods and services for teaching as shown in Figure 1, belongs to the science and education field, is used for doing experiment or an assembly of the use of demonstrating to the student on the classroom.The feed well of existing mold directly is communicated with die cavity along die joint, and when causing the demoulding, product and material handle still link together, and needs again will to expect that handle cuts off from product, many one cutting actions.Required cost of labor of balance on goods and services of moulding is higher, and in addition, during cutting, material handle and product junction cutting part are complete, cause product rejection.
The utility model content
The technical problems to be solved in the utility model is: a kind of balance on goods and services in-mould decoration mould that reduces cost of labor, reduces scrappage is provided.
The solution that the utility model is taked is: a kind of balance on goods and services in-mould decoration mould, comprise male model, master mold, the die joint of described master mold is provided with feed well, feed well is communicated with charging hole, charging hole runs through the framed of master mold, and the case mold cavity wall is provided with a through hole that is communicated with feed well the inner.
Described through hole is inclined to set.
Described master mold is provided with two die cavities.
the beneficial effects of the utility model are: after adopting above structure, the utility model balance on goods and services in-mould decoration mould compared with prior art, have the following advantages: feed well of the present utility model is not directly to extend in die cavity, but will expect again to annotate in die cavity through a through hole, after the benefit of doing like this is exactly shaped article, do not link together between product and material handle (being the part of feed well place's moulding), the defective material that product is placed in the through hole connects, but because through hole is very little, in the time of the demoulding, the defective material bound fraction of product and through hole is sliced off by the through hole edge, when therefore product is located on the top, what obtain has been a finished product that need not again to process, reduce cost of labor and also reduced product rejection rate.
As improvement, described through hole is inclined to set, and the through hole edge is sharper, better the defective material bound fraction of cutting products and through hole.
As improvement, described master mold is provided with two die cavities, so die sinking can obtain two products, has improved production efficiency.
Description of drawings
Fig. 1 is existing balance on goods and services schematic diagram.
Fig. 2 is the male model schematic diagram.
Fig. 3 is the master mold schematic diagram.
Shown in figure: 1, male model, 2, master mold, 2.1, feed well, 2.2, charging hole, 2.3, through hole, 2.4, die cavity.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
With reference to Fig. 1-Fig. 3, a kind of balance on goods and services in-mould decoration of the utility model mould, comprise male model 1, master mold 2, the die joint of described master mold 2 is provided with feed well 2.1, feed well 2.1 is communicated with charging hole 2.2, charging hole 2.2 runs through the framed of master mold 2, is convenient to inject from the back side of master mold 2 material, and master mold 2 die cavity inwalls are provided with a through hole 2.3 that is communicated with feed well 2.1 the inners.The inner die cavity .4 that is communicated with of through hole 2.3.
Described through hole 2.3 is inclined to set, and through hole 2.3 edges are sharper, better the defective material bound fraction at cutting products and through hole 2.3 places.
Described master mold 2 is provided with two die cavities 2.4.Therefore die sinking can obtain two products, has improved production efficiency.
feed well 2.1 of the present utility model is not directly to extend in die cavity 2.4, but will expect again to annotate in die cavity 2.4 through a through hole 2.3, after the benefit of doing like this is exactly shaped article, do not link together between product and material handle (being the part of feed well place's moulding), the defective material that product is placed in the through hole connects, but because through hole is very little, in the time of the demoulding, the defective material bound fraction of product and through hole is sliced off by the through hole edge, when therefore product is located on the top, what obtain has been a finished product that need not again to process, reduce cost of labor and also reduced product rejection rate.
