Abstract
The utility model discloses a drain pan of many ribs of back, including the drain pan, the drain pan back is equipped with the rib, be equipped with the terminal fastener of being convenient for on the drain pan, the middle part level of terminal fastener is equipped with glues the bit plane, the draw-in groove of the binding post joint of being convenient for is seted up to the upper surface of gluing the bit plane in the top of terminal fastener, the slotted hole has been seted up to the lower surface of gluing the bit plane in the drain pan back. Compared with the prior art, the utility model discloses to the research and development design of product, realized the normal demolding of the very big type of product of the packing power of back mould, the mould can reach normal batch production, has improved the yield greatly.
Description
Technical Field
The utility model relates to an injection moulding product especially relates to a drain pan of many ribs of back.
Background
Referring to fig. 1, in the original product, the bottom shell structure cannot be normally demoulded in the process of testing the mould. The rib height 43.45MM of the three terminal clamping pieces is 1.2MM thick, and is high and thin. The clamping groove is directly formed at the bottom shell. All ribs of the bottom shell are arranged on the back surface (the surface connected with the rear die), and because the wrapping force of the rear die is very large, an ejection mechanism cannot be added, and the ribs are clamped on the rear die and cannot be ejected out of the rear die, so that normal mass production cannot be achieved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drain pan of the many ribs of back that has solved above-mentioned problem.
In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a drain pan of many ribs in back, includes the drain pan, the drain pan back is equipped with the rib, be equipped with the terminal fastener of the drawing of patterns of the drain pan of being convenient for on the drain pan, the middle part level of terminal fastener is equipped with glues the bit plane, the draw-in groove of the binding post joint of being convenient for is seted up to the upper surface of gluing the bit plane to the top of terminal fastener, the slotted hole has been seted up to the lower surface of gluing the bit plane to the drain pan back.
Preferably, the inner wall of the slotted hole is provided with a reinforcing rib for increasing the strength.
Preferably, the rib, the terminal clamping piece and the glue position plane are integrally injection molded.
Preferably, the middle lower part of the terminal clamping piece is of a closed hollow structure, and the wall thickness of the middle lower part of the terminal clamping piece is the same as that of other parts of the terminal clamping piece.
Compared with the prior art, the utility model has the advantages of: through the utility model discloses to the research and development design of product, improved the product and glued the problem that the back mould can't the demolding, realized the normal demolding of the very big this type of product of the packing power of back mould, the mould can reach normal batch production, has improved the yield greatly.

fig. 2 is a schematic view of the back structure of the present invention;
FIG. 3 is a schematic view of a prior art product;
fig. 4 is a comparison diagram of the present invention and the original product.
In the figure: 1. a bottom case; 2. ribs; 3. a terminal block; 4. gluing a bit plane; 5. a card slot; 6. a slot; 7. and (5) reinforcing ribs.
Detailed Description
The present invention will be further explained below.
Example 1: referring to fig. 1 to 4, a drain pan of many ribs in back, includes drain pan 1, the back of drain pan 1 is equipped with rib 2, be equipped with the terminal fastener 3 of the drawing of patterns of drain pan 1 of being convenient for on the drain pan 1, the middle part level of terminal fastener 3 is equipped with glues bit plane 4, draw-in groove 5 that the binding post joint of being convenient for is seted up to the upper surface of gluing bit plane 4 in the top of terminal fastener 3, slotted hole 6 has been seted up to the lower surface of gluing bit plane 4 in the back of drain pan 1. The glue level plane 4 on the bottom shell 1 is lifted to the middle of the terminal clamping piece 3, the upper part of the terminal clamping piece 3 forms a clamping groove 5 for clamping a wiring terminal, and the lower part forms an ejection part for ejection stress of ejection mechanisms such as an ejector pin. Because the packing force of the rear mold is very large, the terminal clamping piece 3 is designed to be used as a receiving part of the ejection mechanism, so that the bottom shell 1 is convenient to demold. The back of the bottom shell 1 is thick and needs to be hollowed out from the back to form the slot 6, and the reason for hollowing is to prevent the product from shrinking and deforming after being produced to affect poor appearance. Since the housing is an injection molded product, if the wall thickness of the lower portion of the terminal clip 3 is much thicker than that of the other portions, shrinkage deformation occurs due to slow local cooling, and therefore, it is necessary to cut the slot 6.
Because the terminal clamping piece 3 can be used as an ejection part of the ejection mechanism, the requirement on the structural strength of the part is high, and the reinforcing ribs 7 for increasing the strength are arranged on the inner wall of the slotted hole 6, so that the structural strength of the terminal clamping piece 3 can be increased from the inside of the slotted hole 6. Compared with the original structure that one groove is arranged to the bottom, the middle lower part of the terminal clamping piece 3 is of a closed hollow structure, the structural stability and the structural strength of the terminal clamping piece 3 are greatly increased, the requirement of the terminal clamping piece as an ejection part is met, the wall thickness of the terminal clamping piece is the same as that of other parts of the terminal clamping piece 3, and the terminal clamping piece is cooled uniformly and is not easy to deform. The rib 2, the terminal clamping piece 3 and the glue position plane 4 are integrally molded by injection, so that the integrated molding and processing are convenient, and the structural stability of the product is good.
The above has thoroughly introduced the bottom case with multiple ribs on the back side provided by the present invention, and the specific examples are applied herein to explain the principle and the implementation of the present invention, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
