Description
Technical field
The present invention relates to the manufacturing methods of toy models tire, refer in particular to a kind of integrally formed method of model wheel.
Background technology
At present, there are two types of patterns in production for toy models wheel, and a kind of is respectively to be molded the wheel hub to match, tire
After molding, the two is manually subjected to assembled formation；Another kind is after molding wheel hub is taken out on hub mold, then to pass through people
Work, which enters wheel hub arrangement in tire injection mold, to be molded, and combines the two.In both modes, the former man-made assembly is imitated
Rate is low；The artificial transfering process of the latter is cumbersome, and easily carelessness causes placement position inaccurate, influences product quality.Both
It is easy to cause the problems such as efficiency is low, high labor cost, and product quality is low.
Invention content
It is an object of the invention to be directed to the existing state of the art, a kind of integrally formed method of model wheel is provided,
Model wheel is integrally formed using double-colored machine, production efficiency can be effectively improved, ensures product quality.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：
The present invention is a kind of integrally formed method of model wheel, it is characterised in that：Include the following steps：
（1）The wheel hub of model wheel will be formed, two kinds of injection raw materials of tire are injected separately into the first cover half in double-colored machine, second determines
In the barrel of mould；
（2）Start double-colored machine to complete to be molded for the first time, wheel hub, the second dynamic model are formed after making its first dynamic model and the molding of the first cover half
Without injection after being molded with the second cover half；
（3）After primary die sinking, the first dynamic model carries molding wheel hub, and the second dynamic model is empty mould, and the first dynamic model and the second dynamic model carry out
180 degree rotates, and makes the first dynamic model and the second cover half mold-closing injection tire, the second dynamic model and the first cover half mold-closing injection wheel hub；
（4）After twice-die-opening, the second dynamic model carries molding wheel hub, and the molding model wheel of the first dynamic die liftout completes demoulding, the
One dynamic model and the second dynamic model carry out 180 degree rotation again, mold the first dynamic model and the first cover half, the second dynamic model and the second cover half
It is molded again after molding, and so on, it constantly will be transferred to second by the molding wheel hub of the first cover half by two dynamic models and determine
Tire is molded in mould with synthetic model wheel, then demoulds, collect model wheel, until closing double-colored machine；Closing double-colored machine
When preceding last time is molded, the first cover half exists after molding with corresponding dynamic model without injection, the second cover half with corresponding dynamic model
Molding wheel is ejected after mold-closing injection tire, turns off double-colored machine.
Further, wheel hub is different from the injection raw material color of tire.
In said program, wheel hub is hard material, and tire is soft or hard material.
As the first selection of injection raw material, the injection raw material of wheel hub includes polypropylene, polyamide, colorant；Tire
Injection raw material includes rubber, foaming agent, colorant.
As second of selection of injection raw material, the injection raw material of tire is one or more combinations in TPE, TPR, PVC,
And corresponding colorant.
Beneficial effects of the present invention are：
1. tables of equipment one, it is only necessary to which production can be completed in double-colored machine；
2. in addition to initial setting parameter and after excluding waste material, you can continually produce, almost without manually participating in, efficient,
It is at low cost；
3. product is firmly combined with, true vehicle tire characteristics can be simulated by two kinds of material perfect adaptations, form is complete, uniformly, quality
It is high.
Description of the drawings：
Attached drawing 1 is the schematic diagram of production procedure of the present invention.
Specific embodiment：
The present invention will be further described in conjunction with the embodiments：
As shown in Figure 1, a kind of integrally formed method of model wheel, includes the following steps：
（1）The wheel hub of model wheel will be formed, two kinds of injection raw materials of tire are injected separately into the first cover half A, second in double-colored machine
In the barrel of cover half A'；
（2）Start double-colored machine to complete to be molded for the first time, make its first dynamic model B and the first cover half（A）Wheel hub, second are formed after molding
Without injection after dynamic model B' and the second cover half A' moldings；
（3）After primary die sinking, the first dynamic model B carries molding wheel hub, and the second dynamic model B' is empty mould, the first dynamic model B and the second dynamic model
B' carries out 180 degree rotation, molds the first dynamic model B and the second cover half A' mold-closing injections tire, the second dynamic model B' and the first cover half A
It is molded wheel hub；
（4）After twice-die-opening, the second dynamic model B' carries molding wheel hub, and the first dynamic model B ejects molding model wheel and completes demoulding,
First dynamic model B and the second dynamic model B' carry out 180 degree rotation again, mold the first dynamic model B and the first cover half A, the second dynamic model B'
It is molded again after being molded with the second cover half A', and so on, it constantly will be by the first molding wheel hubs of cover half A by two dynamic models
It is transferred in the second cover half A' and is molded tire with synthetic model wheel, then demould, collect model wheel, until closing double-colored
Machine；In the last time injection before closing double-colored machine, the first cover half A and corresponding dynamic model after molding without injection, second
Cover half A ' ejects molding wheel after mold-closing injection tire with corresponding dynamic model, turns off double-colored machine.
In said program, wheel hub is different from the injection raw material color of tire, and wheel hub is hard material, tire to be soft or
Hard material.And the material matching of the two is by two schemes, it is specific as follows：
The first selection of injection raw material：The injection raw material of wheel hub includes 40% polypropylene, 55% polyamide, 5% colorant；Tire is made
Injection raw material for hard material includes 90% rubber, 5% foaming agent, 5% colorant；Wherein, wheel hub colorant preferred white, tire color
Expect preferred black.
Second of selection of injection raw material：The injection raw material of wheel hub includes 40% polypropylene, 55% polyamide, 5% colorant；Wheel
Injection raw material when tire is as soft material is one or more combinations and corresponding colorant in TPE, TPR, PVC.Wherein,
Wheel hub colorant preferred white, the preferred black of tire colorant.
Certainly, it these are only the better embodiment of the present invention, the use scope of the present invention not limited with this, therefore, it is all
It is to make equivalent change in the principle of the invention should be included within the scope of the present invention.
