Abstract
A cooling device for insert pins in a plastic mold used for processing multi-hole industrial connectors is disclosed. The cooling device comprises a cavity, a core and a plurality of insert pins. Water line mechanisms of the cavity and the core are respectively provided with a water line sealing base plate, a pin fixing plate, a water line plate and a water line sealing middle plate. The plurality of the insert pins pass through the water line plates and the water line sealing middle plates of the cavity and the core and are fixed to the pin fixing plates. The water line sealing base plates are provided with water inlets and water outlets. Each water inlet is communicated with the left ends of the corresponding water line sealing base plate, the corresponding pin fixing plate and the corresponding water line plate. Each water outlet is communicated with the right ends of the corresponding pin fixing plate and the corresponding water line plate. The water line plates are provided with seal grooves. By the manner, the temperature of the insert pins can be reduced rapidly, and a continuous molding cycle is shortened.
Description
Technical field
The present invention relates to machinery manufacturing technology field, particularly relating to pin cooling device in a kind of plastic mold for processing porous industrial connector.
Background technology
In prior art, porous industrial connector is mainly used in the fields such as Medical Devices, Industry Control, detection and measurement device, AV system, the communication of radio and television box, nuclear industry and military project, is a kind of joint of plug and play.
The purpose of design of injection mould cooling system makes product Homogeneous cooling, and within a short period of time ejecting product.Water route cooling refers to and utilize machining through hole out in the mould bases, die of plastic mould, make certain medium (Ru Shui, oil) not pass right down inside circulation, control mould temperature and then control product cool in a mold or shrink to reach, obtain desirable product size and the object of outward appearance.The quality of water route arrangement directly has influence on shaping quality and the molding cycle of product, remote-effects product cost.
The required precision that porous industrial connector connects jack to himself is very high, shrinks or be out of shape the using function after all affecting finished product assembling in hole.And gross distortion directly can affect Product Assembly, components and parts itself are caused to use.Prior art, when carrying out such connector injection mo(u)lding, need use compressed air to enter the long period to shaping mold insert air-cooled.During to avoid product stripping, colloid no solidification and cannot deviate from mould, causes product sticking to mould.
Existing production technology about porous industrial connector is: mould is when continuous seepage, fortune water in pattern benevolence and mould bases reduces mould cavity temperature, but the pin protruded is elongated and close and many, fortune water cannot be led to, extraneous compressed air can only be relied on to carry out air-cooled, the mold insert protruded blows on, and just can carry out next production cycle.This technology is now used comparatively extensive, and is generally approved by industry.But there is the industrial connector of small volume, its cooling cycle, the global formation cycle reached 90s, and production efficiency is low but more than 60s.
Injection moulding this kind of porous industrial connector need arrange a large amount of pin in mould, and the water route processed under prior art only can meet the cooling requirement of outermost part pin, cannot pin inside effective cooling.And it is more to connect jack, in corresponding mould, pin quantity is more, fails the pin quantity of effective cooling also just to increase accordingly.And prior art is when failing to design waterway cooling system in effective mould, adopts the cooling cycle and molding cycle that extend Shooting Technique, having reached the object of cooling shaped article.But this kind of way causes, and production efficiency is too low, unit cost is higher.And to the accuracy requirement of molding parameter too high, cause production technology not easily management and control, fraction defective is higher.
Summary of the invention
The technical problem that the present invention mainly solves is to provide pin cooling device in a kind of plastic mold for processing porous industrial connector, can reach and reduce pin own temperature fast, shorten the object in continuously shaped cycle.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide pin cooling device in a kind of plastic mold for processing porous industrial connector, comprise: front mould, rear mold and Duo Gen pin, the fortune water-bound of described front mould and rear mold is respectively arranged with fortune water-stop base plate from outside to inside, pin fixed head, water carrying board and plate in fortune water-stop, described many pins are each passed through the water carrying board of front mould and rear mold, in fortune water-stop, plate is fixed on pin fixed head, described fortune water-stop base plate offers water inlet and delivery port, described water inlet is communicated with fortune water-stop base plate, the left end of pin fixed head and water carrying board, described delivery port is communicated with the right-hand member of pin fixed head and water carrying board, described water carrying board offers seal groove.
In a preferred embodiment of the present invention, the fortune water-stop base plate of described rear mold offers a suction hole.
In a preferred embodiment of the present invention, described suction hole is communicated with plate in the pin fixed head of rear mold, water carrying board and fortune water-stop.
The invention has the beneficial effects as follows: water-cooled effect of the present invention is more effective, shorten cool time and molding cycle, be stable into shape parameter, enhance productivity, reduce unit cost.
Accompanying drawing explanation
Fig. 1 be the present invention for process porous industrial connector plastic mold in the internal structure schematic diagram of pin cooling device.
In accompanying drawing, the mark of each parts is as follows: 1, front mould; 2, rear mold; 3, pin; 4, water-stop base plate is transported; 5, pin fixed head; 6, water carrying board; 7, plate in water-stop is transported; 40, water inlet; 41, delivery port; 42, suction hole; 60, seal groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: pin cooling device in a kind of plastic mold for processing porous industrial connector, comprise: front mould 1, rear mold 2 and Duo Gen pin 3, the fortune water-bound of described front mould 1 and rear mold 2 is respectively arranged with fortune water-stop base plate 4 from outside to inside, pin fixed head 5, water carrying board 6 and plate 7 in fortune water-stop, described many pins 3 are each passed through the water carrying board 6 of front mould and rear mold, in fortune water-stop, plate 7 is fixed on pin fixed head 5, described fortune water-stop base plate 4 offers water inlet 40 and delivery port 41, described water inlet 40 is communicated with the left end of pin fixed head 5 and water carrying board 6, described delivery port 41 is communicated with the right-hand member of pin fixed head 5 and water carrying board 6, described water carrying board 6 offers seal groove 60.
Furtherly, the fortune water-stop base plate 4 of described rear mold 2 offers a suction hole 42; Described suction hole 42 is communicated with pin fixed head 5, the water carrying board 6 of rear mold 2 and transports plate 7 in water-stop, reduces product in injection moulding process, produces too much bubble.
