Batch production, production efficiency are high.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of compression casting metal fingerprint, including fingerprint body and firm banking, the fingerprint body include palm portion
And finger part, the palm portion and finger part simulate staff structure design, and the fingerprint body is along its longitudinal direction side
To divide into two halves, half is palmar aspect part, and second half is hand back portion, the palmar aspect part and hand back portion pair
A complete fingerprint is constituted after button is fixed.
Further, the fingerprint body is structure as a whole with firm banking, and the firm banking is also divided into two halves structure,
Half is structure as a whole with palmar aspect part, and second half is divided into integrative-structure with the back of the hand face.
Further, the concave surface of the finger part is provided with the reinforcement set in vertical and horizontal.
Further, the palmar aspect part and being fixedly connected using bolt or mode connects for screw, office between hand back portion
The connected mode of portion's spot-welded, local riveting, the connection of refractory metal binding agent or interference fit.
Further, the palmar aspect part and being fixedly connected using bolt or mode connects for screw, office between hand back portion
The connected mode of portion's spot-welded, local riveting, the connection of refractory metal binding agent or interference fit.
Further, after the palmar aspect part and hand back portion make-up are fixed, the palmar aspect part and the back of the hand face
Partial junction is sealed using refractory metal binding agent.
A kind of preparation method of compression casting metal fingerprint, the size requirement first according to fingerprint to be prepared selects phase therewith
Supporting mould, then carries out Metal Melting, using palmar aspect part of the pressure casting machine difference die casting with firm banking
With hand back portion, palmar aspect part and hand back portion are taken out after the completion of die casting, and to palmar aspect part and hand back portion
Overlap and burr cleared up, then using bolt or mode connects for screw, local spot-welded, local riveting, refractory metal
Binding agent is connected or the connected mode of interference fit fixes palmar aspect part and hand back portion make-up, and is used in junction
Refractory metal binding agent is sealed, and eventually passes leak and infiltration test, and up to standard is certified products.
Further, the metal employed in the Metal Melting step is aluminium alloy or magnesium alloy.
The utility model has the following advantages that：
1st, using two halves formula structure, fingerprint point two parts carry out die cast, and overall wall thickness is easily controlled and thickness is uniform,
Wall thickness is most thin to accomplish 0.3mm.
2nd, using two halves formula structure, free from admixture in finger position, good heat conductivity, heat transfer is uniform, heat exchanger effectiveness is high.
3rd, the groove in finger position sets up the reinforcement of horizontal and vertical setting, not only acts as the work of fixed reinforcement
With, but also heat-transfer rate can be increased, it is ensured that fingerprint is heated（Catch a cold）Do not produce thermal stress deformation.
4th, by way of die casting, Al alloys andMg alloys stock utilization is improved, and fingerprint outward appearance smooths light, finish, size
High precision, greatly reduces polishing workload；Labor productivity is significantly improved, production cost reduction.
5th, fingerprint heat exchange（It is heated, cools down）Speed is fast, and integral surface temperature is uniform, gloves impregnating effect is balanced, steady
Fixed, dipping gloves yield rate is significantly improved, energy resource consumption reduction by 15%（Steam consumption）, power consumption decline 10%（Motor work(
Rate）, latex, the curing degree efficiency such as butyronitrile improve 10%, production line balance speed is accelerated, and production efficiency improves about 5--10%.
6th, fingerprint texture exquisiteness even compact, intensity, rigidity, case hardness are high.
7th, can at any time change the fingerprint for having corroded or having damaged, can half change, fingerprint service life further improves.
8th, the fingerprint after die casting is greatly reduced metalworking workload without mechanical Roughing and fine machining, and manufacturing process is most
It is big effectively simplified, fast, greatly reduce employment cost and producing cost etc..
