Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive injection molds, specifically relating to a slider T-shaped fixing mechanism. Background Technology
[0002] For electroplated products made from plastic molds, if there are multiple undercuts on the outside, there is basically no space to design a standard slider core-pulling structure. For example... Figure 1 As shown, due to the limitations of product characteristics and the requirements for size and clamping lines, a common slider structure is generally used. However, due to the influence of product structure, the design space is limited. A common slider will interfere with the ejector block and gate on the mold, making normal injection molding and demolding impossible. If the mold is designed with an angled ejector, the clamping lines cannot be controlled, and electroplating will amplify product defects. Utility Model Content
[0003] To address the aforementioned problems in the existing technology, this utility model provides a slider T-shaped fixing mechanism, which has a simplified and stable structure, occupies little space, and will not interfere with other parts of the mold.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a T-shaped slider fixing mechanism, comprising an inclined guide post, a T-shaped slider, a limiting block, a T-shaped fixing block, and a spring. The bottom of the T-shaped slider is a T-shaped block, which is slidably disposed within the T-shaped fixing block. The upper part of one end of the T-shaped slider is connected to the product. The inclined guide post is obliquely inserted into the T-shaped slider and the T-shaped fixing block, and the inclined guide post is inclined towards the side where the T-shaped slider is connected to the product. The limiting block contacts and limits one side of the upper part of the T-shaped slider. The spring is fixed on the end of the T-shaped slider connected to the product, and the spring is located between the T-shaped block and the connection point between the T-shaped slider and the product. When the mold is opened, the inclined guide post is driven to move vertically upward, and the T-shaped slider is driven by the inclined guide post to move horizontally on the T-shaped fixing block in a direction away from the product until the T-shaped slider is limited by the side limiting block.
[0005] Furthermore, the T-shaped slider has an oblique hollow groove, the bottom of the T-shaped fixing block has an oval hole, the oblique guide post passes through the hollow groove and the oval hole, and the upper middle part of the T-shaped fixing block has a T-shaped groove with a T-shaped side that is adapted to the T-shaped block.
[0006] Furthermore, an indentation is provided on the upper part of one side of the T-shaped slider along the sliding direction, and the indentation is located on the side away from the connection between the T-shaped slider and the product.
[0007] Furthermore, the maximum length of the T-shaped slider perpendicular to the sliding direction is the same as the maximum length of the T-shaped fixed block perpendicular to the sliding direction.
[0008] Compared with the prior art, the advantages of this utility model are: this utility model uses a T-shaped fixing block to fix the T-shaped slider, and the T-shaped slider is driven by the inclined guide post to slide horizontally along the T-shaped groove on the T-shaped fixing block. It occupies little space and has a simplified structure, thereby reducing the space occupied by the slider in the mold and preventing interference with other parts of the mold; moreover, it is easy to disassemble and assemble, and the stable structure is more conducive to the control of the clamping line, improving the stability of production and making maintenance more convenient.

[0015] 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.
[0016] Please participate Figure 1 In the existing technology, when there are multiple undercuts on the outside of the plastic mold electroplating product 6, and there are high requirements for size and clamping lines, a common slider 7 core-pulling structure is generally designed. However, when the common slider 7 is applied to the product 6, it will interfere with the top block 8 and gate 9 in the mold. Therefore, the common slider 7 cannot be arranged on the mold.
[0017] Please see Figure 2-6This utility model provides the following technical solution: a T-shaped slider fixing mechanism, including an inclined guide post 1, a T-shaped slider 2, a limiting block 3, a T-shaped fixing block 4, and a spring 5. The bottom of the T-shaped slider 2 is a T-shaped block 23, which is slidably disposed within the T-shaped fixing block 4. The upper part of one end of the T-shaped slider 2 is connected to the product 6 via an inverted connection. The inclined guide post 1 is obliquely inserted into the T-shaped slider 2 and the T-shaped fixing block 4, and the inclined guide post 1 is inclined towards the side where the T-shaped slider 2 is connected to the product 6. The limiting block 3 contacts and limits one side of the upper part of the T-shaped slider 2. When the T-shaped slider 2 moves backward on the T-shaped fixing block 4, the limiting block 3 abuts against the T-shaped slider 2 after moving a certain distance, and the T-shaped slider 2 stops moving. The spring 5 is fixed on the end of the T-shaped slider 2 connected to the product 6, and the spring 5 is located between the T-shaped block 23 and the connection point between the T-shaped slider 2 and the product 6. When the T-shaped slider... After being installed on the T-shaped fixing block 4, the spring 5 is compressed by the mold and has elastic force. When the mold opens, the inclined guide post 1 is driven to move vertically upward. Since the inclined guide post 1 is inclined towards the product 6 inserted into the T-shaped slider 2 and the T-shaped fixing block 4, the vertical upward movement of the inclined guide post 1 drives the T-shaped slider 2 to move away from the product 6. At the same time, since the spring 5 is compressed, the spring 5 also drives the T-shaped slider 2 to move away from the product 6. The T-shaped slider 2 is driven by the inclined guide post 1 and the spring 5 to move horizontally on the T-shaped fixing block 4 away from the product 6 until the T-shaped slider 2 is limited by the side limiting block 3 and stops sliding. At this time, the T-shaped slider 2 is disengaged from the undercut of the product 6. Compared with the ordinary slider 7, this slider T-shaped fixing mechanism has a simplified structure, occupies less space in the mold, does not interfere with other parts of the mold, has a stable structure, and is conducive to the control of the clamping line.
[0018] Specifically, the T-shaped slider 2 has an inclined hollow groove 21, the bottom of the T-shaped fixing block 4 has an oval hole 42, and the inclined guide post 1 passes through the hollow groove 21 and the oval hole 42. The inclined guide post 1 is initially set on one side of the oval hole 42. When the inclined guide post 1 moves vertically upward, the T-shaped fixing block 4 will not move, and the inclined guide post 1 will gradually move to the other side of the oval hole 42. At this time, the T-shaped slider 2 will move away from the product 6 on the T-shaped fixing block 4. The upper middle part of the T-shaped fixing block 4 has a T-shaped groove 41 with a T-shaped side that matches the T-shaped block 23. The T-shaped block 23 slides along the T-shaped groove 41 and is pushed into the T-shaped fixing block 4.
[0019] Specifically, a recess 22 is provided on the upper side of one side of the T-shaped slider 2 along the sliding direction. The recess 22 is located on the side away from the connection between the T-shaped slider 2 and the product 6. The limiting block 3 is set on the recess 22 and contacts the surface of the recess 22. When the T-shaped slider 2 slides a certain distance away from the product 6, the front of the recess 22 on the T-shaped slider 2 is limited by the limiting block 3.
[0020] Specifically, the maximum length of the T-shaped slider 2 perpendicular to the sliding direction is the same as the maximum length of the T-shaped fixed block 4 perpendicular to the sliding direction. After the T-shaped slider 2 and the T-shaped fixed block 4 are connected, the cross-sectional size is smaller than that of the existing ordinary slider 7, which reduces the space occupied in the mold and will not interfere with the top block 8 and gate 9 on the mold.
[0021] The installation and movement process of this utility model is as follows: First, the inclined guide post 1 is installed into the front mold and locked by the fixing block. Then, the T-shaped fixing block 4 is installed into the rear mold and fixed with screws. The spring 5 is installed into the T-shaped slider 2. Then, the T-shaped slider 2 is pushed into the T-shaped fixing block 4 of the rear mold through the T-shaped groove 41 of the T-shaped fixing block 4. At this time, the inclined guide post 1 is gradually inserted into the hollow groove 21 of the T-shaped slider 2 until it finally penetrates the oval hole 42 on the T-shaped fixing block 4. Finally, the limiting block 3 is fixed to the rear mold with screws. At this time, the limiting block 3 is in contact with the surface of the concave opening 22 on the T-shaped slider 2. When the mold opens, the front mold drives the inclined guide post 1 to move vertically upward. The T-shaped slider 2 is driven by the inclined guide post 1 and the spring 5 to move horizontally on the T-shaped fixing block 4 in a direction away from the product 6 until the T-shaped slider 2 is limited by the side limiting block 3 and stops sliding. At this time, the T-shaped slider 2 is disengaged from the undercut of the product 6. During this movement, the T-shaped fixing block 4 and the limiting block 3 remain fixed.
[0022] When electroplated products 6 have large-angle undercuts on the outside, this utility model can solve the problems of mold complexity, space size, and disassembly / assembly, increase mold strength, and avoid wasting mold production and manufacturing costs.
[0023] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
