Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a two-way inward sliding block structure. Background Technology

[0002] When the outer cover plate is injection molded, the molding hole and the front edge need to be pulled out separately. However, the distance between these two core pulling positions is relatively close, and they will interfere with each other during the core pulling operation. The current solution is to use a separate drive mechanism to complete the core pulling operation, which leads to a complex mold structure and increases mold and maintenance costs. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of the prior art and provide a two-way inward sliding block structure that is simple in structure and convenient for removing the sliding block.

[0004] This utility model also provides a mold with a simple structure and convenient removal of the slider.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] The first aspect of this utility model provides a two-way inward sliding block structure, comprising:

[0007] A first slider is connected to a first driving member. The first slider is provided with multiple positioning groups. The first driving member can drive the first slider to move from a first stroke position to a second stroke position along a first direction. The first slider is provided with a stop portion.

[0008] The second slider is connected to the second driving member. The second slider is provided with a positioning part. The second driving member can drive the second slider to move from the third stroke position to the fourth stroke position along the second direction.

[0009] The second direction intersects with the first direction. When the first slider is at the first stroke position and the second slider is at the third stroke position, the stop portion of the first slider abuts against the second slider to prevent the first slider from moving from the first stroke position to the second stroke position along the first direction.

[0010] The first slider includes a first sliding body, which has a first slot for the output shaft of the first drive member to be engaged, and a stop portion is provided at one end of the first sliding body away from the first slot, and the stop portion is provided with the positioning group.

[0011] The positioning group includes a first positioning post and a plurality of second positioning blocks disposed on the stop portion. The first positioning post and the plurality of second positioning blocks protrude from the stop portion, and the plurality of second positioning blocks are spaced vertically from the first positioning post, with a gap formed between adjacent two second positioning blocks.

[0012] The stop portion consists of multiple stop blocks disposed on the first sliding body and extending upward relative to the first sliding body.

[0013] The second slider includes a connecting block, on which a support block extending along a second direction is provided. The support block is provided with a stop surface that can abut against the stop part. The positioning part is a positioning groove provided on the second slider. The connecting block is provided with a second slot that allows the second driving component to be engaged.

[0014] The support block is provided with a support surface, and the second slider is also provided with a bent first arc surface. One end of the first arc surface is connected to the support surface, and a second arc surface is provided between the side wall surface corresponding to the first arc surface and the stop surface of the second slider. The positioning groove is provided between the first arc surface and the second arc surface.

[0015] The aforementioned two-way inward sliding block structure also includes a base and a connecting plate inclined relative to the base. The first driving member is disposed on the base, and the first slider slides on the connecting plate and can slide relative to the connecting plate.

[0016] The first slider is connected to a sliding rod that can slide with it, and the base is also provided with a backing component that can abut against the sliding rod to prevent the sliding rod from moving further.

[0017] The top support assembly includes a first top block and a second top block connected to the base. The first top block and the second top block are spaced apart to form a sliding space in which the sliding rod can slide. The first top block and the second top block are also provided with protrusions protruding into the sliding space. The base is also provided with a first movable groove in which the output shaft of the first drive member can move. The base is also provided with a second movable groove in which the sliding rod can slide.

[0018] The second aspect of this utility model provides a mold, comprising: a two-way inward sliding block structure as described above.

[0019] Compared with existing technologies, this invention has the following advantages: When in use, the first slider is located at the first stroke position, and the second slider is located at the second stroke position. During injection molding, the product is positioned by multiple positioning groups of the first slider and the positioning part of the second slider. When the product needs to be removed, the second drive is activated, driving the second slider to move along the second direction. The second slider moves from the third stroke position to the fourth stroke position. During this process, the second slider gradually separates from the stop of the first slider to make way for the movement of the first slider. The first drive is then activated, carrying the first slider along the first direction. The first slider gradually moves from the first stroke position to the second stroke position. During this process, multiple positioning groups gradually separate from the product, allowing the product to be removed. This is very convenient. Furthermore, during production, the cooperation between the second and first sliders facilitates product positioning and molding. When demolding is required, the second and first drive components sequentially separate the second and first sliders from the product, avoiding interference. The structure is simple, occupies little space, and is more compact overall. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] like Figures 1 to 8 As shown, a two-way inward sliding block structure includes: a first slider 1 connected to a first driving member 2, wherein the first slider 1 is provided with a plurality of positioning groups 11, and the first driving member 2 can drive the first slider 1 to move from a first stroke position to a second stroke position along a first direction X, and the first slider 1 is provided with a stop part 12; a second slider 3 connected to a second driving member 4, wherein the second slider 3 is provided with a positioning part 31, and the second driving member 4 can drive the second slider 3 to move from a third stroke position to a fourth stroke position along a second direction Y; wherein the second direction intersects with the first direction, and when the first slider 1 is located at the first stroke position and the second slider 3 is located at the third stroke position, the stop part 12 of the first slider 1 abuts against the second slider 3 to prevent the first slider 1 from moving from the first stroke position to the second stroke position along the first direction.

[0031] When this utility model is in use, the first slider 1 is located at the first stroke position, and the second slider 3 is located at the second stroke position. At this time, the product is injection molded and positioned by the multiple positioning groups 11 of the first slider 1 and the positioning part 31 of the second slider 3. When the product needs to be removed, the second driving member 4 is activated. After the second driving member 4 is activated, it drives the second slider 3 to move along the second direction. The second slider 3 moves from the third stroke position to the fourth stroke position. During this process, the second slider 3 gradually separates from the stop part 12 of the first slider 1 and makes way for the movement of the first slider 1. The first driving member 2 is activated. After the first driving member 2 is activated, it carries the first slider 1 to move along the first direction. The first slider 1 gradually moves from the first stroke position to the second stroke position. During this process, the multiple positioning groups 11 gradually separate from the product, and the product can be removed. It is very convenient to use. Moreover, during production, the cooperation between the second slider 3 and the first slider 1 facilitates product positioning and molding. When demolding is required, the second driving component 4 and the first driving component 2 drive the second slider 3 and the first slider 1 to separate from the product sequentially, which can avoid interference. The structure is simple, occupies little space, and makes the overall structure more compact.

[0032] The first slider 1 includes a first sliding body 13. The first sliding body 13 is provided with a first slot 131 for the output shaft of the first driving member 2 to be engaged. A stop portion 12 is provided at one end of the first sliding body 13 away from the first slot 131, and a positioning group 11 is provided on the stop portion 12. The first slot 131 facilitates the installation and positioning of the output shaft of the first driving member 2, and the stop portion 12 is located at the end of the first sliding body 13 for easy processing.

[0033] The positioning group 11 includes a first positioning post 111 and a plurality of second positioning blocks 112 disposed on the stop portion 12. The first positioning post 111 and the plurality of second positioning blocks 112 protrude from the stop portion 12, and the plurality of second positioning blocks 112 are arranged vertically and vertically spaced from the first positioning post 111, and a gap is formed between two adjacent second positioning blocks 112.

[0034] The first positioning post 111 is not only used to position the product, but also facilitates the processing of the product's holes. The multiple second positioning blocks 112 are not only used to position the product, but also facilitate the processing of the product's structure. Since there is a gap between two adjacent second positioning blocks 112, the two adjacent second positioning blocks 112 also have a clamping and positioning function, making the connection more stable.

[0035] The stop portion 12 consists of multiple stop blocks disposed on the first sliding body 13 and extending upward relative to the first sliding body 13, so as to facilitate abutting against the second slider 3.

[0036] The second slider 3 includes a connecting block 32, on which a support block 33 extending along a second direction is provided. The support block 33 is provided with a stop surface 331 that can abut against the stop part 12. The positioning part 31 is a positioning groove provided on the second slider 3. The connecting block 32 is provided with a second slot 321 that allows the second driving member 4 to be engaged. The second slot 321 facilitates the engagement of the output shaft of the second driving member 4. The stop surface 331 facilitates abutment against the stop part 12, preventing the second slider 3 from sliding relative to the first slider 1.

[0037] The supporting block 33 is provided with a supporting surface 332, and the second slider 3 is also provided with a bent first arc-shaped surface 333. One end of the first arc-shaped surface 333 is connected to the supporting surface 332, and a second arc-shaped surface 334 is provided between the first arc-shaped surface 333 and the side wall surface corresponding to the stop surface 331 of the second slider 3. The positioning groove is provided between the first arc-shaped surface 333 and the second arc-shaped surface 334. The supporting surface 332 facilitates product support. The positioning groove is not only used for shaping and producing products, but also supports the front end of the product.

[0038] The bidirectional inward sliding block structure further includes a base 5 and a connecting plate 6 inclined relative to the base 5. The first driving member 2 is disposed on the base 5, and the first slider 1 slides on and relative to the connecting plate 6. The base 5 facilitates the installation of this bidirectional inward sliding block structure, and the connecting plate 6 facilitates the sliding of the first slider 1.

[0039] The first slider 1 is connected to a sliding rod 7 that can slide with it, and the base 5 is also provided with a backing component 8 that can abut against the sliding rod 7 to prevent the sliding rod 7 from moving further. The cooperation between the sliding rod 7 and the backing component 8 can limit the forward and backward position of the first slider 1.

[0040] The abutment assembly 8 includes a first abutment block 81 and a second abutment block 82 connected to the base 5. The first abutment block 81 and the second abutment block 82 are spaced apart to form a sliding space 83 within which the sliding rod 7 can slide. The first abutment block 81 and the second abutment block 82 are also provided with protrusions 84 extending into the sliding space 83. The protrusions 84 can abut against the sliding rod 7, causing the sliding rod 7 to abut against the first abutment block 81 or the second abutment block 82. The sliding space 83 limits the distance the sliding rod 7 can move. It is conceivable that the first abutment block 81 and the second abutment block 82 are electromagnets, and the protrusions 84 are magnetic abutments, which can more stably position the sliding rod 7.

[0041] The base 5 is also provided with a first movable groove 41 that allows the output shaft of the first driving member 2 to move within it, and a second movable groove 42 that allows the sliding rod 7 to slide.

[0042] The first movable groove 41 and the second movable groove 42 are designed to facilitate the fixing of the first driving member 2 and the sliding rod 7, so that they do not interfere with each other when they move.

[0043] A mold includes a two-way inward sliding block structure 9 as described above. When this invention is in use, the first slider 1 is located at the first stroke position, and the second slider 3 is located at the second stroke position. At this time, the product is injection molded, and the product is positioned by the multiple positioning groups 11 of the first slider 1 and the positioning part 31 of the second slider 3. When the product needs to be removed, the second driving member 4 is activated. After the second driving member 4 is activated, it drives the second slider 3 to move along the second direction. The second slider 3 moves from the third stroke position to the fourth stroke position. During this process, the second slider 3 gradually separates from the stop part 12 of the first slider 1 and makes way for the movement of the first slider 1. The first driving member 2 is activated. After the first driving member 2 is activated, it carries the first slider 1 to move along the first direction. The first slider 1 gradually moves from the first stroke position to the second stroke position. During this process, the multiple positioning groups 11 gradually separate from the product, allowing the product to be removed. This method is very convenient to use. Moreover, during production, the cooperation between the second slider 3 and the first slider 1 facilitates product positioning and molding. When demolding is required, the second driving component 4 and the first driving component 2 drive the second slider 3 and the first slider 1 to separate from the product sequentially, which can avoid interference. The structure is simple, occupies little space, and makes the overall structure more compact.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
