Abstract
The utility model discloses a plastic mould for demoulding from a product with an inverted button, which comprises a panel, a sprue bush, a top clamp plate, an upper mold core, an upper mold core fixing plate, a moveable template, a fixed template, a lower mold core, a fixed mould fixing plate, a backing plate, a limiting bolt, a nozzle spring needle and a nylon mould button. As the limiting boltis arranged between the upper mold core fixing plate and the moveable template, and the nylon mould button is arranged between the moveable template and the fixed template, the upper mold core fixed on the upper mold core fixing plate is guaranteed to be separated firstly from a mould cavity, thus vacating certain contracting space for the inverted button part on the external wall of the product,causing the product to be contracted inwards, separating the fixed template and the fixed mould fixing plate which are fixedly connected together from the backing plate, separating the lower mold corefrom the product with the inverted button without damaging the product, guaranteeing the appearance requirement of the product, and shortening the production cycle.
Description
Technical field
The utility model relates to a kind of mould of plastics, particularly relates to a kind of mould of plastics of the demoulding from have the back-off product.
Background technology
The structure of the plastic product on the existing market becomes increasingly complex, and many plastic products all have back-off, and this just requires mould can inject this back-off, requires to have a kind of structure that mould is extracted out from have the back-off product that can be intact simultaneously.For the back-off part of product is deviate from from core smoothly, when mould designs, need to go up earlier core and extract out, so that vacate certain shrink space for product with outer wall back-off.
The utility model content
The purpose of this utility model is to provide a kind of mould of plastics of the demoulding from have the back-off product, and it can deviate from mould and not damage product from the product with back-off structure.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of mould of plastics of the demoulding from have the back-off product, and it comprises panel, sprue bush, mouth of a river plate, last core, goes up core fixing plate, moving platen, solid plate, descends core, cover half fixed head, backing plate, first stop screw, second stop screw, the 3rd stop screw, mouth of a river bullet pin and nylon mould to buckle; Described sprue bush is fixed on the middle part of panel, and the ladder of mouth of a river bullet pin upper end is movable to be nested with on the panel and its upper end leans cascaded surface at sprue bush by spring on, and panel and mouth of a river plate are passed over against runner in the lower end of mouth of a river bullet pin; Described solid plate and cover half fixed head are by screw locking together; The described core of going up is installed on the core fixing plate and penetrates moving platen downwards, following core installation cover half fixed head and be upward through solid plate to stretch into moving platen relative with last core; Between panel and mouth of a river plate, first stop screw is housed, second stop screw is housed between last core fixing plate and moving platen and branch mould spring also is housed, nylon mould button is housed between moving platen and solid plate, the 3rd stop screw is housed between cover half fixed head and backing plate and branch mould spring also is housed.
After adopting such scheme, because the utility model is provided with stop screw between last core fixing plate and moving platen, nylon mould button is housed between moving platen and solid plate, thereby the last core that has guaranteed to be fixed on the core fixing plate at first breaks away from from mold cavity, partly vacateed certain shrink space for the back-off of product outer wall, product can inwardly be shunk, the solid plate that is fixed together separates with backing plate with the cover half fixed head, to descend core from have the back-off product, to deviate from, and can not damage product, guarantee the appearance requirement of product, shorten the production cycle.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is a structure chart of the present utility model;
Fig. 2 is the schematic diagram that the utility model running channel stub bar breaks away from running channel;
Fig. 3 is the schematic diagram that core breaks away from product on the utility model;
Fig. 4 is the schematic diagram that core breaks away from product under the utility model;
Fig. 5 is the schematic diagram that the utility model product breaks away from fully.
The specific embodiment
As shown in Figure 1, the utility model is a kind of mould of plastics of the demoulding from have the back-off product, and it comprises panel 1, sprue bush 2, mouth of a river plate 3, last core 4, goes up core fixing plate 5, moving platen 6, solid plate 7, descends core 8, cover half fixed head 9, backing plate 10, first stop screw 20, second stop screw 30, the 3rd stop screw 40, mouth of a river bullet pin 50 and nylon mould to buckle 60.
Described sprue bush 2 is fixed on the middle part of panel 1, movable being nested with in the through hole 11 of panel 1 in ladder upper end of mouth of a river bullet pin 50, and its upper end leans on the cascaded surface of sprue bush 2 by spring 501, panel 1 and mouth of a river plate 3 are passed over against runner in the lower end of mouth of a river bullet pin 50, can lean on the stub bar of runner, stub bar is ejected from runner, sprue; Described solid plate 7 passes through screw locking together with cover half fixed head 9; The described core 4 of going up is installed on the core fixing plate 5 and penetrates moving platen 6 downwards, and following core 8 is installed cover half fixed heads 9 and is upward through solid plate 7 and stretches into moving platen 6, and is relative with last core 4, the part of formation mold cavity; First stop screw 20 is housed between panel 1 and mouth of a river plate 3, second stop screw 30 is housed between last core fixing plate 5 and moving platen 6 and branch mould spring 70 also is housed, nylon mould button 60 is housed between moving platen 6 and solid plate 7, the 3rd stop screw 40 is housed between cover half fixed head 9 and backing plate 10 and branch mould spring 70 also is housed.
The utility model die sinking process:
1, as shown in Figure 2, mouth of a river plate 3 separates with last core fixing plate 5, and mouth of a river bullet pin 50 ejects stub bar 100 under the effect of spring 501 elastic force from runner, sprue;
2, as shown in Figure 3, last core fixing plate 5 and moving platen 66 separate under the 70 elastic force effects of minute mould spring, the last core 4 that is fixed on the core fixing plate 5 at first breaks away from from mold cavity, has partly vacateed certain shrink space for the back-off of product 200 outer walls, and product 200 can inwardly be shunk;
3, as shown in Figure 4, the solid plate 7 that is fixed together separates with backing plate 10 with cover half fixed head 9, will descend core 8 to deviate from from product 200;
4, as shown in Figure 5, moving platen 6 separates fully with solid plate 7, and nylon mould button 60 is thrown off, and product 200 is deviate from from die cavity fully.
