Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, and in particular to a mold for fixing a UV lamp for a water softener. Background Technology

[0002] The improved UV lamp mounting bracket for water softeners has barbs on the side. If the existing mold is used, firstly, the structure of the UV lamp mounting bracket for water softeners is not compatible with the mold; secondly, it is impossible to design ejector pins based on the existing mold; and thirdly, because the mold clamping force of the UV lamp mounting bracket for water softeners is relatively large, during injection molding, phenomena such as sticking to mold parts, such as a certain slider, often occur, resulting in a low product qualification rate and extended production cycle for the UV lamp mounting bracket for water softeners.

[0003] Therefore, there is an urgent need to design a new mold for fixing a UV lamp in an injection-molded water softener with a hook-shaped side. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a mold for fixing a UV lamp in a water softener.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The technical solution of this invention is to provide a mold for fixing a UV lamp for a water softener, used to prepare an injection-molded UV lamp fixing bracket product with a barbed structure on the side, such as a screw post or a groove shape. The mold for fixing a UV lamp for a water softener includes:

[0007] The front mold is equipped with angled guide pillars;

[0008] The rear mold includes a slider B that slides horizontally, a slider A that slides horizontally and limits the position of a barb on the UV lamp mounting bracket for the water softener, and a first slider insert that is fixedly connected to the slider B and used to insert into the UV lamp mounting bracket for the water softener. The inclined guide post passes through the slider B and slides with it. The slider A is also provided with a second connector, and the slider B is also provided with a groove into which the second connector slides. The shape of the groove and the second connector satisfies the condition that the second connector will not detach from the groove.

[0009] The front mold and the rear mold also form a cavity for injection molding the UV lamp fixing bracket product of the water softener. When the inclined guide post is pulled out from the slider B, it first drives the first slider insert to leave the UV lamp fixing bracket product of the water softener, and then drives the slider A to leave the UV lamp fixing bracket product of the water softener, thus completing the demolding of the UV lamp fixing bracket product of the water softener.

[0010] In some specific embodiments, the rear mold core of the rear mold is provided with a first connecting member for holding the slider A.

[0011] In some specific embodiments, the first connector is a nylon opener / closer.

[0012] In some specific embodiments, the first connector and the rear mold core are detachable structures.

[0013] In some specific embodiments, the first connector is fixed to the rear mold core by screws.

[0014] In some specific embodiments, the slider B has a hole through which the inclined guide post passes.

[0015] In some specific embodiments, the slider A is further provided with a second slider insert that extends into a barb of the UV lamp fixing bracket of the water softener.

[0016] In some specific embodiments, the second connector is a height-equalizing screw.

[0017] In some specific embodiments, the tilt angle of the inclined guide post is greater than 0 and less than 90°.

[0018] In some specific embodiments, the rear mold is further provided with a limiting block for limiting the slider B.

[0019] Compared with existing technologies, this invention is applicable to the manufacture of injection-molded UV lamp mounting brackets for water softeners with side barbed structures such as screw posts or grooves. These products, due to their high clamping force, are prone to sticking to the slider during demolding, thus reducing production efficiency. This invention, however, achieves a secondary demolding effect by first removing the first insert embedded in the product and then removing the slider that contacts the barb, effectively solving the problem of high clamping force and slider sticking.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] In the following embodiments, unless otherwise specified, the functional components or structures are conventional components or structures used in the art to achieve the corresponding functions.

[0029] Example 1:

[0030] like Figure 1-3 The image shows a mold for fixing a UV lamp in a water softener, comprising:

[0031] The front mold 1 is equipped with inclined guide pillars 3;

[0032] The rear mold 2 is provided with a slider B4 that slides horizontally, a slider A5 that slides horizontally and limits the barb of the water softener UV lamp fixing bracket product, and a first slider insert 6 that is fixedly connected to the slider B4 and used to insert into the water softener UV lamp fixing bracket.

[0033] The slider B4 has a hole through which the inclined guide post 3 passes, and the inclined guide post 3 passes through the hole in the slider B4 and slides with it. The slider A5 is also provided with a second connecting member 8, which is, for example, a height-equalizing screw. The slider B4 is also provided with a groove into which the second connecting member 8 slides, and the shape of the groove and the second connecting member 8 satisfies the condition that the second connecting member 8 will not disengage from the groove.

[0034] The front mold 1 and the rear mold 2 also form a cavity for injection molding the UV lamp fixing bracket product of the water softener. When the inclined guide post 3 is pulled out from the slider B, it first drives the first slider insert 6 to leave the UV lamp fixing bracket product of the water softener, and then drives the slider A5 to leave the UV lamp fixing bracket product of the water softener, thus completing the demolding of the UV lamp fixing bracket product of the water softener.

[0035] To prevent displacement of slider A5 during demolding, the rear mold core of the rear mold 2 is provided with a first connecting member 7 for holding slider A5. For example, the first connecting member 7 is a nylon opener / closer, which is fixed to the rear mold core by screws.

[0036] The slider A5 is also provided with a second slider insert 10 that extends into a barb of the UV lamp fixing bracket of the water softener, which is used to limit the UV lamp fixing bracket product of the water softener during injection molding.

[0037] The tilt angle of the inclined guide post 3 is greater than 0 and less than 90°. For example, the tilt angle of the inclined guide post 3 is 45°.

[0038] The rear mold 2 is also provided with a limiting block 9 for limiting the slider B4. When the slider B4 slides to the limiting block 9, the inclined guide post 3 separates from the slider B4, and the slider B4 stops moving.

[0039] During injection molding, the inclined guide post 3 on the front mold 1 is inserted into the hole of the slider B4 on the rear mold 2. As the inclined guide post 3 goes deeper, the slider B4 drives the first slider insert 6 to move inward together. When the equalizing screw slides to the point where the slider B4 contacts the slider A5, the slider B4 pushes the slider A5 to continue sliding inward together, so that the first slider insert 6 is inserted into the fixing bracket of the water softener UV lamp. When the slider A5 slides to the rear mold core of the rear mold 2, the second slider insert 10 on the slider A5 is also inserted into the barb of the fixing bracket of the water softener UV lamp. Because the nylon opener sticks to the slider A5, the slider A5 stops sliding, and the mold closing is completed.

[0040] During injection molding, as the inclined guide post 3 on the front mold 1 moves away from the hole of the slider B4 on the rear mold 2, slider B4 is also driven to slide outward. This causes slider B4 to drive the first slider insert 6 to slide outward for demolding. Since slider A5 is held onto the rear mold 2 by the nylon opener / closer, slider A5 cannot move, thus preventing the product from sticking to slider A5 during demolding. Furthermore, because the equalizing screw slides within the groove of slider B4, when one end of the equalizing screw contacts the end of the groove of slider B4, the first slider insert 6 is sufficient to complete demolding. As the inclined guide post 3 continues to pull out, it continues to drive slider B4 outward. The equalizing screw, under the tension of slider B4, also drives slider A5 outward, separating slider A5 from the nylon opener / closer, thus completing the complete demolding of the water softener UV lamp mounting bracket. When slider B4 slides to the limit block 9, the inclined guide post 3 and slider B4 completely separate, slider B4 stops sliding, and one operation is completed.

[0041] The above description of the embodiments is provided to enable those skilled in the art to understand and use the invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
