Abstract
The utility model discloses an improved mould cavity of a character wheel, which comprises a cavity and a feeding female core. The mould cavity of the character wheel is characterized in that the feeding female core is an individual capable of separated from the cavity, a sprue bushing is sleeved outside the feeding female core, and the cavity is provided with a feeding female core channel in the same shape as the sprue bushing. In the utility model, a mould cavity for producing character wheels of both motorcycles and automobiles is improved, the cost is saved, and the operating efficiency is improved; as the female core is not required to be changed, so that the manufactured products have no error, and the qualification rate of the products is greatly improved.
Description
Technical field
The utility model relates to a kind of mold cavity of plastics character wheel, particularly a kind of improved character wheel mold cavity.
Background technology
In the field of existing use character wheel, the plastics character wheel is produced easy-formation because of it, light accurately and frequency of utilization is the most extensive.Motorcycle, automobile, or water meter, electric energy meter one class need the accurately product of counting, all is common plastics character wheels.
For plastic product, the certain first-selected injection mo(u)lding of production method, by charging aperture raw material is fed die cavity and carry out high-temperature injection, the mold cavity that shortcoming is to use the charging body core can occur and exceed the cavity bottom plane after processing is after a while used, the product of producing like this is not owing to there is the full raw material of filling to process, and the product of being produced is underproof, must change whole die cavity, also can't the secondary utilization by the die cavity changed, production cost is high; In addition, change after the other cover die cavity, how many products of institute's injection mo(u)lding has certain error, influential to the postchannel process production and processing; At last, change the chronic of die cavity, need stop whole machinery usually, could start machinery once more after the replacing installation, influence ordinary production.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of improved character wheel mold cavity, the charging body core and the die cavity body of original one are carried out the split design, body core can take out replacing, improved production efficiency, and body core does not change has long-time stability to postchannel process, saves production cost, increases work efficiency greatly.
The utility model is to realize by following technical scheme:
A kind of improved character wheel mold cavity comprises die cavity and charging body core, and described charging body core is the independent individual that can separate with die cavity, is with sprue bush in charging body core outside, and described die cavity contains the charging body core passage identical with the sprue bush shape.
Described sprue bush is the different two-segment type structure of width with charging body core passage.Installation is more compact like this, can not be out of shape, and has prolonged service time.
The beneficial effects of the utility model are:
(1) provides cost savings, improved operating efficiency;
(2), make the postchannel process of product that long-time stability be arranged with a collection of product size indifference;
(3) changing the time of the present utility model is original 1/10th of a whole set of die cavity time of changing, and makes that whole process need not to shut down, and saves time and the energy.
Description of drawings
Fig. 1 is the mold cavity that prior art is produced the plastics character wheel
Fig. 2 is the character wheel mold cavity after the utility model improves
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, be the mold cavity that prior art is produced the plastics character wheel, comprise die cavity 1; charging body core 2 and charging aperture 3 are when producing the plastics character wheel, from charging aperture 3 chargings; carry out processing, after using a period of time, because charging aperture 3 is through long-time wearing and tearing; it is big that charging aperture becomes; have remaining cast gate to stay on the product, product can't assemble and cause product rejection, must change the whole die cavity of same model; and shut down, putting into production after replacing is finished.
As Fig. 2, be the character wheel mold cavity after the utility model improves, comprise die cavity 1 and charging body core 2, described charging body core 2 is the independent individuals that can separate with die cavity, be with sprue bush 4 in charging body core 2 outsides, described die cavity 1 contains the charging body core passage 5 identical with the sprue bush shape.
Described sprue bush 4 is the different two-segment type structures of width with charging body core passage 5.Installation is more compact like this, can not be out of shape, and has prolonged service time.
After beginning to carry out the character wheel processing, raw material enters charging body core 2 from charging aperture 3, as prior art; after using a period of time; because charging aperture 3 is through long-time wearing and tearing, it is big that charging aperture becomes, and has remaining cast gate to stay on the product; product can't assemble and cause product rejection; need only this moment and change sprue bush 4, and do not touch the mechanical power source part, can not shut down direct replacing; save the time and the energy that start once more, improved production efficiency and qualification rate greatly.
Claims (2)
1. improved character wheel mold cavity, comprise die cavity and charging body core, it is characterized in that described charging body core is the independent individual that can separate with die cavity, be with sprue bush in charging body core outside, described die cavity contains the charging body core passage identical with the sprue bush shape.
2. improved character wheel mold cavity as claimed in claim 1 is characterized in that described sprue bush and charging body core passage are the different two-segment type structures of width.
