Abstract
The utility model provides a mould for injection sol coating and off-center prevention of a long and thin rod. The mould comprises a distribution shuttle, a guide ring, a movable mould core and a fixed mould core, wherein the movable mould core and the fixed mould core are used for injection molding. The distribution shuttle is in a bullet shape, a plurality of spiral distribution grooves are arranged on the surface of the distribution shuttle, and the distribution shuttle is arranged at one ends of mould cavities of the movable mould core and the fixed mould core and communicated with a runner of the fixed mould core. The guide ring is arranged in the mould cavities of the movable mould core and the fixed mould core and can move in the mould cavities. By adding the distribution shuttle at the top end of the long and thin rod, sol can evenly enter the cavities of the mould cavities after being distributed by the distribution shuttle. Therefore, the top end of the long and thin rod can be effectively fixed, and the fed sol is even in the sol feeding process. The off-center problem of the long and thin rod can be solved in the sol coating process of the long and thin rod, and the rejection rate of injection molding parts is greatly reduced.
Description
Technical field
The utility model discloses a kind of for the anti-eccentric mould of elongate rod injection moulding encapsulate, can prevent effectively that down spare is eccentric.The injection mold technical field.
Background technology
The elongate rod encapsulate requires encapsulate distance, wall thickness uniformity, in actual production process, because the elongate rod bending strength is poor, be placed on and carry out encapsulate in the mould, there is following several situation all to cause product eccentric and scrap: to advance glue from the side of elongate rod, elongate rod can be advanced under the glue laminated power to produce flexural deformation in side direction, causes off-centre.Advance glue from the elongate rod top, do not have the strong point in the middle of the elongate rod, under the self gravitation effect or elongate rod have in some slight deformation situations, the distortion of elongate rod is strengthened gradually, it is eccentric that elongate rod is produced, generation is scrapped.More than two kinds of situations can cause accepted product percentage very low, produce a large amount of wastes.
Summary of the invention
It is a kind of for the anti-eccentric mould of elongate rod injection moulding encapsulate that the utility model provides, and in the elongate rod encapsulation process, can prevent effectively that down spare is eccentric, greatly improves the qualification rate of product.
The anti-eccentric mould of the disclosed elongate rod injection moulding of the utility model encapsulate, the method solution is as follows:
Comprise spreader, guide ring and injection molding moving-mould-core and cover half core; Described spreader is the bullet type, and its surface has several helical shunt grooves; Spreader is installed in die cavity one end of moving-mould-core and cover half core, is communicated with the runner of cover half core; The guide ring device can move at die cavity in the die cavity of moving-mould-core and cover half core.
During use elongate rod (workpiece) is fixed on the spreader, the shaft in elongate rod puts guide ring simultaneously, then will be put into together and carry out injection moulding production in the mold cavity, die sinking after injection moulding is finished, to take out together, spreader will be separated with guide ring, finish injection moulding process.
Good effect of the present utility model is: the top of elongate rod adds a spreader, makes colloidal sol first by entering uniformly mold cavity after the spreader shunting.So both effectively the elongate rod top was fixed, and in advancing the glue process, can makes into glue again even.In the elongate rod encapsulation process, can effectively solve the problem of elongate rod off-centre, greatly reduce the percent defective of moulding.
Description of drawings
Fig. 1 is the utility model structural principle;
1. spreaders among the figure, 2. moving-mould-core, 3. runner, 4. elongate rod, 5. guide ring, 6. cover half core, 7. thimble, 8. die cavity.
The specific embodiment
According to shown in Figure 1, the utility model comprises upper spreader 1, guide ring 5 and the injection molding moving-mould-core 2 and the cover half core 6 that are installed in elongate rod 4; Described spreader 1 is the bullet type, and its surface has several helical shunt grooves (in the present embodiment being three); Spreader 1 is installed in die cavity 8 one ends of moving-mould-core 2 and cover half core 6, is communicated with the runner 3 of cover half core 6; Guide ring 5 devices can move at die cavity 8 in the die cavity 8 of moving-mould-core 2 and cover half core 6.
Front end in elongate rod 4 is installed a spreader 1, and guide ring 5 is sleeved on elongate rod 4 afterbodys, and device is in the die cavity 8 of moving-mould-core 2; Mold-closing injection, after cooling die sinking, elongate rod 4 is together taken out by thimble 7 jack-up of cover half core 6 bottoms together with spreader 1, then elongate rod 4 is separated with spreader 1, guide ring 5, has finished the production of elongate rod encapsulated products.
