Description
Technical Field
The utility model belongs to the technical field of the exterior trimming part, concretely relates to kennel structure suitable for high mobility material of moulding plastics and exempt from to coat the material.
Background
At present, aiming at high-fluidity injection molding materials (such as PP) and coating-free materials, the dog nest structure on the back easily causes the defects of surface shrinkage, appearance bonding line and the like, but due to the characteristic problems of the high-fluidity injection molding materials and the coating-free materials, the structure can not completely improve the problems under many conditions, and has the main defects that: 1. the appearance defects of the product cannot be eliminated; 2. in order to improve the appearance shrinkage defect, the injection molding pressure maintaining is increased, and other problems such as product deformation out of tolerance and the like are caused; 3. the modification cost of the mould is caused for improving the defects; 4. the development period is prolonged, and the development cost is increased; 5. there is a risk of after-market complaints.
Disclosure of Invention
The utility model aims to solve the technical problem to provide an improve high mobility injection moulding material and exempt from to coat material appearance defect problem to the current situation of prior art, make size and the easier management and control of appearance stability, shorten development cycle, reduce development cost, reduce the dog nest structure who is applicable to high mobility injection moulding material and exempt from to coat material of complaining after sale.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a kennel structure suitable for high mobility material of moulding plastics and exempt from to scribble material, a serial communication port, including product somatic part, kennel portion and latch part, latch part install the upper end at kennel portion, kennel portion has the through-hole groove, the lower extreme root of kennel portion have and make kennel portion not overlap joint to the complete hollow department at the back of product somatic part, be provided with the rib at the side of kennel portion and the back of product somatic part, the side of kennel portion and the back of product somatic part are connected to the rib.
In the above doghouse structure suitable for the high-fluidity injection molding material and the coating-free material, the root of the upper end of the doghouse part and the back of the body part of the product are provided with the glue reducing part.
Compared with the prior art, the utility model has the advantages of improve high fluidity injection molding material and exempt from coating material appearance defect problem, make size and the easier management and control of appearance stability, shorten development cycle, reduce development cost, reduce the after-sale complain of.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
In the figure, a product body portion 1; a dog nest portion 2; a fastening part 3; a through-hole groove 4; a glue reducing part 5; a completely hollowed part 6; ribs 7; a lower end root 8; upper root 9.
As shown in fig. 1 and 2, the dog house structure suitable for high-fluidity injection molding material and coating-free material comprises a product body part 1, a dog house part 2 and a buckling part 3, wherein the buckling part 3 is installed at the upper end of the dog house part 2, the dog house part 2 is provided with an opening groove 4, the buckling part 3 is used for installation and fixation, as shown in fig. 3 and 4, an upper end root part 9 of the dog house part 2 and the back surface of the product body part 1 are provided with a glue reducing part 5, so that the appearance of the product body part 1 is prevented from being influenced, as shown in fig. 5, 6 and 7, a lower end root part 8 of the dog house part 2 is provided with a completely hollowed part 6, which enables the dog house part 2 not to be overlapped with the back surface of the product body part 1, a rib body part 7 is arranged on the side edge of the dog house part 2 and the back surface of the product body part 1, the rib 7 connects the side edge of the dog house part 2 and the back surface of the product body, product wall thickness's sudden change arouses product noumenon 1 surface to shrink very easily, so this patent structure is when the design, empty lower extreme root 8 with dog nest portion 2, reduce the influence to the material stream, improve the appearance defect problem, exempt from the coating material for reaching the metallic effect, most has added metal powder, because metal powder is miniature sheet structure, different sheet structure can cause the difference of outward appearance, lower extreme root 8 of dog nest portion 2 is because the back of overlap joint product noumenon 1, can produce the material stream disorder at these structures, thereby cause appearance defect, so this patent structure is when the design, empty lower extreme root 8 of dog nest portion 2 completely, reduce the influence to the material stream, improve the appearance defect problem.
