Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a molding mold for an air conditioner wind deflector cover. Background Technology

[0002] Injection molding is a molding method in which thermoplastic or thermosetting plastic is melted by heating and injected into a mold cavity under high pressure, and then cooled and solidified to obtain a plastic product. The mold is one of the most critical components in injection molding, and the quality and precision of the mold directly affect the quality and performance of the final product.

[0003] The air conditioner deflector cover is an injection-molded plastic part with a very complex inner surface structure. It has irregularly shaped wire clips and multiple scattered clips on the bottom surface. Because the wire clips have horizontal wire holes and the clips face forward, when the mold is opened, if it is opened horizontally with the wire clips as the reference, the structure at the clips will be damaged. If it is opened back and forth with the clips as the reference, the structure at the wire clips will also be damaged. Therefore, these wire clips and clips cannot be demolded directly at the same time. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model discloses a molding die for an air conditioner deflector cover, including a lower die 1 and an upper die 2. The lower die 1 is inlaid with guide pillars 3 around its perimeter, and the upper die 2 is inlaid with guide sleeves 4 around its perimeter. The upper die 2 is closed with the lower die 1 through the guide sleeves 4 and guide pillars 3. When the die is opened, under the elastic tension of the return spring 113, the inclined push rod 112 can be forced to move laterally, causing the slider seat 111 to move backward, thereby causing the lateral molding insert 115 to exit, achieving the purpose of opening the die with the lateral snap fastener. Then, the ejection mechanism drives the wire snap fastener 18, the mold cavity ejector 19 and the T-shaped ejector 110 to work together to achieve the purpose of vertical opening of the product and the wire snap fastener on the product. The steps are clear and reasonable, making the die design more reasonable and avoiding the problem of mutual interference during demolding.

[0025] The lower mold 1 includes a lower fixed plate 11, mold feet 12, male mold plate 13, and male mold insert 14. The mold feet 12 are installed at both ends of the lower fixed plate 11, the male mold plate 13 is installed on the mold feet 12, and the male mold insert 14 is embedded in the male mold plate 13. A lower top plate 15 is installed on the lower fixed plate 11, and an upper top plate 16 is installed on the lower top plate 15. An urethane column 17, a wire clip ejector pin 18, and a mold cavity ejector pin are respectively installed on the upper top plate 16. 19 and T-shaped ejector pin 110, and the wire-clamping ejector pin 18, the mold cavity ejector pin 19 and the T-shaped ejector pin 110 all extend into the male mold insert 14. The two ends of the male mold insert 14 are slidably connected to the slider seat 111, and the slider seat 111 is movably fitted with the inclined push rod 112. The bottom end of the inclined push rod 112 is equipped with a return spring 113. The two ends of the slider seat 111 are clamped with the wedge block 114, and the wedge block 114 is inlaid with the forming insert pin 115.

[0026] The upper mold 2 includes an upper fixing plate 21, a mother mold 22 and a mother mold insert 23. The mother mold 22 is installed on the upper fixing plate 21, the mother mold insert 23 is embedded in the mother mold 22, and pads 24 are embedded at both ends of the mother mold 22.

[0027] Specifically, both the male mold plate 13 and the male mold insert 14 are provided with a lower cooling channel 116, and the lower cooling channels 116 between the two are interconnected.

[0028] In this embodiment, during the injection molding process, the mold is affected by high temperature. The lower cooling channel 116 can quickly absorb the heat in the lower mold 1 through the circulating cooling water or coolant, thereby reducing the mold temperature, keeping the mold within a suitable working temperature range, avoiding problems such as mold deformation, thermal stress and thermal fatigue, and enabling the product to cool and solidify rapidly, thereby shortening the production cycle.

[0029] Specifically, the male template 13 has waist-shaped holes 117 at both ends, and the waist-shaped holes 117 correspond to the position of the inclined push rod 112. The reset spring 113 is located in the waist-shaped holes 117.

[0030] In this embodiment, the waist-shaped hole 117 is a clearance structure to facilitate the movement of the inclined push rod 112, and also to provide installation space for the return spring 113.

[0031] Specifically, the male template 13 is provided with a positioning protrusion 118 at its edge, and the female template 22 is provided with a positioning recess 25 at its edge, and the positioning recess 25 and the positioning protrusion 118 are movably engaged together.

[0032] In this embodiment, by using the precise dimensions and shapes of the positioning concave block 25 and the positioning protrusion 118, it is possible to ensure that all parts of the mold are accurately aligned during mold closing, thereby guaranteeing the dimensional accuracy of the product.

[0033] Specifically, the pad 24 and the wedge block 114 are positioned correspondingly and are engaged together.

[0034] In this embodiment, the pad block 24 and the wedge block 114 have two main functions: first, to cooperate with the ejection mechanism for demolding; and second, to have the same function as the positioning recess block 25 and the positioning protrusion block 118.

[0035] Specifically, both the mother mold 22 and the mother mold insert 23 are provided with upper cooling channels 26, and the upper cooling channels 26 between the two are interconnected.

[0036] In this embodiment, the upper cooling channel 26 can quickly absorb the heat in the upper mold 2 through the circulating cooling water or coolant, thereby reducing the mold temperature, keeping the mold within a suitable working temperature range, avoiding problems such as mold deformation, thermal stress and thermal fatigue, and enabling the product to cool and solidify rapidly, thereby shortening the production cycle.

[0037] Specifically, a gate seat 27 is embedded in the middle of the upper fixing plate 21, and a molten material flow channel 28 is provided in the middle of both the mother mold plate 22 and the mother mold insert 23, and the molten material flow channel 28 is connected to the gate seat 27.

[0038] In this embodiment, during the injection molding process, the gate seat 27 can control the flow rate of the material, ensuring that the plastic is evenly filled in the mold cavity, reducing the resistance during plastic cutting and extrusion, and improving molding efficiency.

[0039] In use, the lower mold 1 and the upper mold 2 are closed with the lower mold 1 through the guide sleeve 4 and the guide post 3. When the mold is closed, as the upper mold 2 is pressed down, the inclined push rod 112 will be forced to move inward and drive the slider seat 111 forward, so that the lateral forming insert 115 reaches the designated position point. When the mold is opened, under the elastic tension of the return spring 113, the inclined push rod 112 can be forced to move inward and drive the slider seat 111 to move backward, so that the lateral forming insert 115 is removed, realizing the purpose of opening the mold with the lateral snap. Afterward, the ejection mechanism drives the wire snap ejector pin 18, the mold cavity ejector pin 19 and the T-shaped ejector pin 110 to work together to realize the purpose of vertical mold opening of the product and the wire snap on the product. The steps are clear and reasonable, making the mold design more reasonable and avoiding the problem of mutual interference during demolding.

[0040] In summary, when the air conditioner deflector cover molding mold is opened, the elastic tension of the return spring 113 forces the inclined push rod 112 to move laterally, causing the slider seat 111 to retract, thereby causing the lateral molding insert 115 to exit, achieving the purpose of opening the mold for the lateral snap-fit. Then, the ejector mechanism drives the wire snap-fit ​​ejector pin 18, the mold cavity ejector pin 19, and the T-shaped ejector pin 110 to work together to achieve the purpose of vertical mold opening of the product and the wire snap-fit ​​on the product. The steps are clear and reasonable, making the mold design more reasonable and avoiding the problem of mutual interference during demolding.
