Description
Technical Field
[0001] The utility model belongs to the technical field of pet supplies and relates to a dog house structure of a spray-free injection molded part. Background Technique
[0002] With the improvement of living standards, pets are becoming more and more popular among people. Among them, the number of dogs raised is the largest. Raising a dog requires a specific dog house. There are many types of dog houses on the market at present, but most dog houses are obtained by injection molding and require the use of injection molds. However, in the process of product molding of traditional injection molds, due to the small demolding angle of the dog house product itself, it is easy to cause the risk of the mold ejecting the mold firmly, preventing top white, top convex, and root fracture, and it is difficult to ensure the stability of the dog house because the stiffness and strength of the dog house ensure the strengthening components during the injection molding process.
[0003] Based on the above, we designed a dog house structure of a spray-free injection molded part. Summary of the Invention
[0004] The purpose of the utility model is to provide a dog house structure of a spray-free injection molded part to solve the problems raised in the above background technique.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A dog house structure of a spray-free injection molded part, including an injection molded dog house body, two first reinforcing ribs, two second reinforcing ribs, and two third reinforcing ribs. A dog house opening communicating with the injection molded dog house body is opened on the front surface of the injection molded dog house body. The two first reinforcing ribs are integrally injection molded at the edge of the injection molded dog house body. The two third reinforcing ribs are integrally injection molded on the back surface of the injection molded dog house body. The two second reinforcing ribs are arranged on both sides of the injection molded dog house body;
[0006] The injection molded dog house body includes a left outer side of the dog house, a right outer side of the dog house, a back side of the dog house, a front side of the dog house, and a top surface of the dog house skylight. The included angle formed between the left outer side of the dog house and the right outer side of the dog house is not less than 15°;
[0007] The tops of the two first reinforcing ribs, the tops of the two second reinforcing ribs, and the tops of the two third reinforcing ribs all extend to the top surface of the dog house skylight. The included angle between the horizontal edge line and the hypotenuse edge line of the first reinforcing rib is 55°.
[0008] In the above dog house structure of a spray-free injection molded part, the distance W between the left outer side of the dog house and the right outer side of the dog house is between 28 mm ≤ W ≤ 65 mm, and the depth D between the back side of the dog house and the front side of the dog house is between 20 mm ≤ D ≤ 25 mm. The purpose of such a setting is to adopt reasonable dimensions to ensure a sufficient travel of the inclined ejector of the mold under appropriate conditions, ensure sufficient installation space for the spring nut for the dog, and ensure the overall stability of the dog house.
[0009] In the above doghouse structure of the spray-free injection molded part, the injection molded doghouse body is composed of a lower housing plate and an upper housing plate. The lower housing plate and the upper housing plate are integrally injection molded. The lower housing plate is composed of an inner housing surface and two housing side surfaces. The two housing side surfaces are respectively connected to both ends of the inner housing surface. The angle between the upper edge line and the lower edge line of the housing side surface is not less than 3°. The maximum height of the housing side surface is not greater than 5 mm, and the minimum height of the housing side surface is 2.5 mm. The purpose of such a setting is to adopt an appropriate demolding angle, avoid the risk of the mold ejector sticking to the mold, prevent the phenomena of top white, top convex, and root fracture, and ensure that the injection molded doghouse body has high gloss after mold opening without subsequent spraying.
[0010] Furthermore, the wall thickness of the lower housing plate is one-third of the wall thickness of the upper housing plate, and the wall thickness T of the upper housing plate is between 2.8 mm ≤ T ≤ 3.2 mm. The purpose of such a setting is to ensure the stiffness and strength of the doghouse with the smallest possible thin wall height under the condition of meeting the mold size, and at the same time, it can reduce the use of raw materials.
[0011] In the above doghouse structure of the spray-free injection molded part, a skylight ventilation hole is provided in the middle of the top surface of the doghouse skylight. The skylight ventilation hole is communicated with the doghouse opening. The height H of the doghouse opening is between 15 mm ≤ H ≤ 75 mm. The purpose of such a setting is that the skylight ventilation hole facilitates the ventilation of the pet dog and ensures that a good air flow can be formed at the doghouse opening, reducing the breeding of bacteria inside the doghouse.
[0012] Compared with the prior art, the advantages of the doghouse structure of the spray-free injection molded part of the present utility model are as follows: The first reinforcing rib is integrally injection molded at the edge of the injection molded doghouse body, the third reinforcing rib is integrally injection molded on the back of the injection molded doghouse body, and the second reinforcing rib is provided on both sides of the injection molded doghouse body, which can enhance the stiffness, increase the fastening stress release area, and prevent appearance marks; at the same time, it improves the overall stiffness, prevents the doghouse from deforming due to excessive torque during screw fastening, the root turning white or breaking, and the height of the reinforcing rib extends to the top, and the angle c is about 55°, ensuring the width of the reinforcing rib. The above dimensions ensure that the reinforcing rib provides sufficient stiffness and strength to ensure the stability of the doghouse.
[0013] The included angle formed between the left outer side surface of the doghouse and the right outer side surface of the doghouse is not less than 15°. A larger demolding angle is adopted to avoid the risk of the mold ejector sticking to the mold, prevent top white, top convex, and root fracture; the angle between the upper edge line and the lower edge line of the housing side surface is not less than 3°. An appropriate demolding angle is adopted to avoid the risk of the mold ejector sticking to the mold, prevent top white, top convex, and root fracture.
[0014] Set the wall thickness of the lower nest plate to one-third of the wall thickness of the upper nest plate, and the wall thickness T of the upper nest plate is between 2.8 mm ≤ T ≤ 3.2 mm. Under the condition of meeting the mold size, a thin wall height as small as possible ensures the stiffness and strength of the dog house, and at the same time can reduce the use of raw materials.

[0021] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the dog house structure of the spray-free injection molded part of the present invention;
[0023] The dog house includes an injection-molded dog house body 1, two first reinforcing ribs 3, two second reinforcing ribs 4, and two third reinforcing ribs 5. A dog house opening 8 communicating with the injection-molded dog house body 1 is provided on the front of the injection-molded dog house body 1. A skylight ventilation hole 2 is provided in the middle of the top surface 105 of the dog house skylight, and the skylight ventilation hole 2 communicates with the dog house opening 8. The design of the skylight ventilation hole 2 facilitates the ventilation and lighting of the pet dog and ensures good air flow between the dog house opening 8 and the injection-molded dog house body 1, reducing the growth of bacteria inside the dog house.
[0024] Embodiment 1: As Figure 1 described, the two first reinforcing ribs 3 are integrally injection-molded at the edge of the injection-molded dog house body 1, the two third reinforcing ribs 5 are integrally injection-molded on the back of the injection-molded dog house body 1, and the two second reinforcing ribs 4 are provided on both sides of the injection-molded dog house body 1. The tops of the two first reinforcing ribs 3, the tops of the two second reinforcing ribs 4, and the tops of the two third reinforcing ribs 5 all extend to the top surface 105 of the dog house skylight. The included angle between the horizontal edge line and the inclined edge line of the first reinforcing rib 3 is 55°.
[0025] The design of this solution can enhance the stiffness of the injection-molded dog house body 1, increase the fastening stress release area, and prevent appearance marks. At the same time, it improves the overall stiffness, prevents the dog house from deforming under excessive torque during screw fastening, whitening or breaking at the root, and the height of the reinforcing rib extends to the top, and the angle c is about 55°, ensuring the width of the reinforcing rib. The limitation of the angle ensures that the first reinforcing rib 3, the second reinforcing rib 4, and the third reinforcing rib 5 provide sufficient stiffness and strength to ensure the stability of the dog house.
[0026] Embodiment 2: As Figure 2 shown, the injection-molded dog house body 1 includes a left outer side surface 101 of the dog house, a right outer side surface 102 of the dog house, a back side surface 103 of the dog house, a front side surface 104 of the dog house, and a top surface 105 of the dog house skylight. The included angle formed between the left outer side surface 101 and the right outer side surface 102 of the dog house is not less than 15°.
[0027] Furthermore, in terms of dimension settings, the distance W between the left outer side surface 101 and the right outer side surface 102 of the dog house is between 28 mm ≤ W ≤ 65 mm, and the depth D between the back side surface 103 and the front side surface 104 of the dog house is between 20 mm ≤ D ≤ 25 mm; the height H of the dog house opening 8 is between 15 mm ≤ H ≤ 75 mm.
[0028] In Embodiment 2, reasonable dimensions are adopted to ensure sufficient installation space for the reed nut for the dog under a suitable ejector stroke of the mold, and the overall stability of the dog house.
[0029] On the basis of Embodiment 2, in order to accommodate dogs of different body sizes, for every 10 mm increase in the height dimension H, one additional horizontal reinforcing rib must be added; and for every 20 mm increase in the width dimension W, one additional vertical reinforcing rib must be added.
[0030] Embodiment 3: As Figure 3 and Figure 4 shown, the injection-molded dog house body 1 is composed of a lower housing plate 6 and an upper housing plate 7. The lower housing plate 6 and the upper housing plate 7 are integrally injection-molded. The lower housing plate 6 is composed of a housing inner surface 601 and two housing side surfaces 602. The two housing side surfaces 602 are respectively connected to both ends of the housing inner surface 601; the angle between the upper edge line and the lower edge line of the housing side surface 602 is not less than 3°. The angle between the upper edge line and the lower edge line of the housing side surface 602 is defined as the demolding B angle, and this angle is not less than 3°. A suitable demolding angle can avoid the risk of the mold ejector getting stuck in the mold and prevent whitening, bulging, and root fracture.
[0031] Further, referring to Figure 3 , the maximum height of the housing side surface 602 is not greater than 5 mm, and the minimum height of the housing side surface 602 is 2.5 mm, that is, the height of the housing inner surface 601 is set; the wall thickness of the lower housing plate 6 is set to be one-third of the wall thickness of the upper housing plate 7, and the wall thickness T of the upper housing plate 7 is between 2.8 mm ≤ T ≤ 3.2 mm; the design of the wall thickness dimension can ensure the stiffness and strength of the dog house with a relatively small thin-wall height while meeting the mold size requirements.
