Abstract
The invention discloses an injection mould core for a refrigerator fan frame, and belongs to the field of injection moulds. The injection mould core comprises three needle point pouring gates, namely a needle point pouring gate 1, a needle point pouring gate 2 and a needle point pouring gate 3, wherein the needle point pouring gates have two diameter sizes; the needle point pouring gate 1 has a relatively large diameter size and is independently positioned on one side of the mould core; the diameter sizes of the needle point pouring gate 2 and the needle point pouring gate 3 are the same and are smaller than that of the needle point pouring gate 1; the needle point pouring gate 2 and the needle point pouring gate 3 are distributed on the other side of the mould core. The injection mould core has the advantages as follows: according to CAE (computer aided engineering) simulation, the three needle point pouring gates with different diameter sizes are optimally designed, and according to the maximum flow length/wall thickness, a specific pouring position is determined so as to transfer a welding mark during injection moulding production of the refrigerator fan frame from an original weak position to a relatively strong end surface, so that the development cost of the mould is greatly reduced, the product quality is improved and thus the service life of a refrigerator cooling fan is prolonged.
Description
Technical field
The present invention relates to injection molding technical field, be specially a kind of fan of refrigerator housing injection cores.
Background technology
Refrigerator radiator fan generally comprises flabellum, fan outer gimbal support and electromagnetic assembly, and fan outer gimbal support is as the support member of fan attachment flabellum and electromagnetic assembly, and its service life on radiator fan, impact was very large.
Refrigerator radiator fan is generally placed in refrigerator or compressor room, therefore very strict to its structural performance requirements, the fan housing of conventional refrigerator radiator fan is moulding, in process of production, injection (mo(u)lding) machine is or/and when subsidiary engine is unstable, and on the low side when penetrating pressure/pressurize or material temperature, the forward position forming weld mark is difficult to fuse, such weld mark produces at the little thin frame of cross-sectional area and when bearing external force, easily ruptures.Existing fan housing injection gate is generally all designed to the same standard, therefore can not evade the problem producing weld mark at weakness.
Summary of the invention
The present invention for the technical problem that solves for providing a kind of fan of refrigerator housing injection cores, in order to weld mark is shifted out thin frame, it designs three different pin gates of diameter dimension according to after CAE simulative optimization, makes weld mark move on to stronger section from original weakness.
Technical solution problem of the present invention adopts following technical scheme:
A kind of fan of refrigerator housing injection cores, it is characterized in that: described fan of refrigerator housing injection cores contains three pin gates, described pin gate has the diameter of two sizes, and larger-size pin gate is separately in side, and two pin gates that size is less are distributed in opposite side.
As preferred embodiment, the determination of described its pin gate position of fan of refrigerator outer shell injection mold core is as follows: can contain within max-flow length/wall ratio maximum product area enter to water position.
As preferred embodiment, the diameter dimension of described pin gate, according to CAE simulative optimization, makes weld mark move on to stronger end face from original weakness.
The present invention is compared with existing injection technique, its beneficial effect is: design three different pin gates of diameter dimension according to CAE simulative optimization, and determine concrete to enter to water position according to max-flow length/wall thickness, the weld mark of fan of refrigerator housing when injecting production is moved on to stronger end face from original weakness, greatly reduce the development cost of mould, improve the quality of product, and then improve the service life of refrigerator radiator fan.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fan of refrigerator housing of the present invention injection cores.
Number in the figure: 1 is a pin gate, 2 is No. two pin gates, and 3 is No. three pin gates.
Detailed description of the invention
The technological means realized to make the present invention, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
As shown in Figure 1, a kind of fan of refrigerator housing injection cores, described fan of refrigerator housing injection cores contains three pin gates, be respectively a pin gate 1, No. two pin gates 2 and No. three pin gates 3, pin gate has the diameter of two sizes, a more independent side at core rod of pin gate 1 diameter dimension, and No. two pin gates are identical with the dead size of No. three pin gates, and less than a pin gate size, be distributed in the opposite side of core rod.
The determination of its pin gate position of fan of refrigerator outer shell injection mold core is as follows: can contain within max-flow length/wall ratio maximum product area enter to water position.
The diameter dimension of pin gate, according to CAE simulative optimization, makes weld mark move on to stronger end face from original weakness.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
