Description
Technical field
The utility model belongs to body-building apparatus technical field, and in particular to a kind of dumbbell and dumbbell head encapsulation die.
Background technology
Dumbbell is a kind of auxiliary appliance of weight lifting and exercise, due to it is easy to use, take up an area it is small, increasingly by vast
The favor of fitness enthusiasts.Dumbbell has one handle, and a dumbbell head is arranged with the handle both ends, to be hold by one hand hand during use
Handle, the purpose of motion or weight training is reached by moving arm muscles repeatedly.
For general motion equipment or weight training equipment, dumbbell belongs to small-sized equipment, deeper compared with other large-scale equipment
Enter daily life, therefore outside practicality, not only for the convenience form in its use and the higher level of security requirement,
More pleasing appearance can be had to show the personal taste of user and style by expecting dumbbell.
Dumbbell head is manufactured using cast iron mostly, is the damage for avoiding causing ground or floor when directly being contacted with ground, often
In dumbbell head peripheral hardware clad, traditional dumbbell head clad uses polyurethane more（PU）, polyurethane（PU）The entitled poly- ammonia of Chinese
Carbamate, due to the simple modification formula of its needs, the physical properties such as different density, elasticity, rigidity can be obtained, at present
Glass fibre thermal insulation material, timber, traditional rubber products etc. are largely substituted.But the more difficult tune of PU Shooting Technique, because
If its smaller temperature of injection window is too high, mobility can be very good, if temperature is too low, and possible short shot, so adjusting
Section gets up to waste time and energy.At present, when dumbbell producer coats PU layers on the outside of dumbbell head, use pours or directly to encapsulation die more
The modes of interior filling PU pieces, it is necessary in 150 ~ 200 DEG C, 63 ~ 200MPa, 10 ~ 30min of hot pressing could be molded using hydraulic press, into
The type time is grown, low production efficiency, and polyurethane（PU）About 2.4 ten thousand yuan/ton of cost, caused polyurethane（PU）Waste material again not
It can reuse, so the clad of dumbbell head is very high using the cost of polyurethane.
TPU（Thermoplastic polyurethanes）Entitled TPUE rubber, mainly has poly-
Point of ester type and polyether-type, its hardness range is wide, wear-resisting, oil resistant, transparent, elastic good, in commodity, sports goods, toy, dress
The fields such as exterior material are used widely, and halogen-free flameproof TPU can also replace flexible PVC to meet the environmental protection in more and more fields
It is required that.TPU hardness range is wide, by changing the proportioning of each reactive components of TPU, can obtain the product of different hardness, and
With the increase of hardness, its product still keeps good elasticity and wearability；High mechanical strength：The bearing capacity of TPU products, resist
Impact and damping performance protrude；Processing characteristics is good, the processing method of common thermoplastic can be used to be processed, such as noted
Modeling, extrusion, calendering etc..
At present, the molding mode of the encapsulated layer of dumbbell head mainly has following three kinds：First, hot-forming using sheet rubber, it is adopted
Mould is as shown in figure 9, the Kazakhstan being made up of including bottom end cover, middle sleeve and upper press cover, bottom end cover left and right bottom end cover
Husband's structure, when encapsulated, a dumbbell head is placed on above the workbench of rubber coating machine first, the remainder of dumbbell is located at workbench
Lower section, then bottom end cover is positioned between dumbbell head and workbench, middle sleeve is enclosed on the outside of dumbbell head, now, Xiang Zhongtao
Sheet rubber is clogged between cylinder and dumbbell head, clogs and covers upper press cover in the upper of sheet rubber after overflowing middle sleeve upper end to sheet rubber
It is square, press-fitting mould under hydraulic press, pressurize, after deflation cycles certain time, die sinking, dumbbell is taken out, completes the encapsulated of single dumbbell head
Layer.This encapsulated formable layer technique is common process, is had the disadvantage that：The encapsulated layer of a dumbbell head can only be once molded,
Low production efficiency；The sheet rubber clogged between middle sleeve and dumbbell head need to be more than actually required rubber mass, thus every time it is encapsulated all
Have a surplus material, and can not reuse, waste serious；Sheet rubber uses PU pieces more, and taste is big, not environmentally, has on the encapsulated layer of shaping
Two circle parting lines, and outward appearance is not especially smooth, poor visual effect.2nd, TPU slurries injection moldings, its injection used are utilized
Mould is as shown in Figure 10, and it is three template dies, when encapsulated, one of dumbbell head is placed in injection mold, another dumbbell head
It is clamped in the claw below mould, TPU slurries is then injected into die cavity, it then follows conventional injection molding process injection molding is mute
The encapsulated layer of bell head.Because being molded using TPU slurries, without feed back, waste of material will not be produced, but can only once be molded
The encapsulated layer of one dumbbell head, low production efficiency；It is still with two circles on the encapsulated layer after shaping and injection mold is three template dies
Parting line, poor visual effect.Above two molding mode be single be molded a dumbbell head encapsulated layer, low production efficiency,
To solve the problem, there is the third molding mode, the molding mode is also to use Shooting Technique, its injection mold used
As shown in figure 11, it is two template dies, a thimble is respectively set in the left and right ends of die cavity, the end of two dumbbell heads is provided with and thimble head
Dumbbell is fixed in mould by the positioning hole of matching, the thimble at both ends, then utilizes the encapsulated layer of injection machine injection molding.The injection
The mode of encapsulated layer is molded, can once be molded the encapsulated layer of two dumbbell heads of dumbbell simultaneously, but because using thimble fixation side
Formula, when encapsulated, the position of thimble can not be wrapped by, thus it is encapsulated after the completion of, dumbbell cephalic par have one piece it is not encapsulated
Region, usual manner be using end cap bonding or be fastened on dumbbell head, by leak iron region seal up, but bond or fasten
End cap easily come off, reduce product quality.Because the allotment of TPU slurries it is blocked up or it is excessively dilute be all unfavorable for injection molding, injection is mute
During the encapsulated layer of bell head, the allotment of its concentration needs operator's rich experience, material component and debugged repeatedly just succeed,
It is so still rare by the use of TPU as dumbbell head cover material.For hexagonal dumbbell, because if it happens it revolves in injection mold
Turn that leakage iron situation just occurs, along with the bad allotment of TPU slurries, not yet occur the encapsulated of hexagonal dumbbell head in the market
Layer uses TPU materials.
