Description

Technical Field

[0001] This utility model relates to the field of mold opening technology, specifically a mold structure with a slider-delayed mold opening mechanism. Background Technology

[0002] For deep-cavity products, the mold clamping force of the fixed mold is too large. When the mold is opened, the product is easily carried away by the fixed mold, which can cause the product to be torn or even cracked. This poses a great risk to product quality and seriously affects production efficiency and quality.

[0003] In a typical slider structure, the mold opens laterally when the fixed mold and the moving mold open together. During mold opening, the sprue can only be pulled out of the slider first before the slider can open. Otherwise, the sprue head will break off in the slider, causing damage to the mold and the product. Utility Model Content

[0004] The purpose of this invention is to provide a mold structure for delayed opening of a slider, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mold structure for a slider with delayed mold opening includes a slider base and a slider. The end of the slider is fixedly inserted into the inside of one end of the slider base. A through hole is opened on the surface of the slider base, and a sliding block is slidably inserted into the through hole. A delay gap is provided between the sliding block and the inner wall of the slider base. This delay gap allows the sliding block to move at least 10mm in vertical height before contacting the slider base.

[0006] In the initial stage, the sliding block is located on the inner wall of the through hole of the slider seat. The sliding block consists of two parts: the upper part is a vertically arranged rectangular column structure, and the lower part is an inclined rectangular column. Its inclination direction is close to the inner wall of the through hole of the slider seat. The upper and lower parts are rigidly connected to form a regular rectangular column with an inclined angle. A recessed transition groove is opened at the corner of the sliding block. A protrusion is provided on the inner wall of the through hole of the slider seat. When the sliding block moves in the vertical direction, the inclined column of its lower part will slowly approach the inner wall of the slider seat on the other side. At this time, the transition groove of the sliding block fits with the protrusion, so that the block drives the slider seat to move, thereby pulling the slider to one side to achieve the demolding of the slider.

[0007] As a further embodiment of this utility model, a glue inlet is provided on one side of the surface of the slider, into which a flow channel can be inserted. The other end of the slider is connected to a mold, and the bottom end of the mold is provided with a moving mold side forming part.

[0008] As a further improvement of this utility model, a buffer part is provided at the transition groove of the sliding block. The buffer part is mainly designed as a transition structure with buffering function at the transition groove, such as opening a rounded corner transition structure.

[0009] As a further embodiment of this utility model, one end of the slider seat is fixedly connected to the slider seat pressure block.

[0010] As a further embodiment of this utility model, the tip of the protrusion of the slider seat is provided with a mating part, and the end of the protrusion of the slider seat is a sliding surface, the height of which determines the height of the protrusion of the slider seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When using this utility model, by setting a delay gap, when the outlet of the flow channel is inserted into the inlet and extends into the interior of the slider, the inlet needs to be pulled out of the slider when the mold is opened. At this time, the setting of the delay gap allows the sliding block to have a period of free rotation before pulling the slider seat to contact, leaving time for the inlet to be pulled out, ensuring that the inlet material head will not break in the slider and preventing damage to the inlet material head.

[0012] 2. When this utility model is used, the buffer part gradually fits into the mating part, preventing direct hard collision between the sliding block and the slider seat during the demolding process. In long-term use, it can protect the mating stability between the slider seat and the sliding block and increase the service life of the demolding parts. Attached Figure Description

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In this invention, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this invention is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use this invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this invention with unnecessary detail. Therefore, this invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.

[0020] Example Please see Figures 1-4 In this embodiment of the utility model, a mold structure for a slider with delayed mold opening includes a slider seat 6 and a slider 5. The end of the slider 5 is fixedly inserted into the inside of one end of the slider seat 6. A through hole is opened on the surface of the slider seat 6, and a sliding block 7 is slidably inserted into the through hole. A delay gap 9 is provided between the sliding block 7 and the inner wall of the slider seat 6. This delay gap 9 allows the sliding block 7 to move at least 10mm in vertical height before contacting the slider seat 6. In the initial stage, the sliding block 7 is close to the inner wall of the through hole of the slider seat 6. The sliding block 7 consists of two parts: the upper part is a vertically set rectangular column structure, and the lower part is an inclined rectangular column with its inclination direction close to the inner wall of the through hole of the slider seat 6. The upper and lower parts are rigidly connected to form a regular rectangular column with an inclination angle.

[0021] A recessed transition groove is provided at the corner of the sliding block 7, and a protrusion is provided on the inner wall of the through hole of the slider seat 6. When the sliding block 7 moves in the vertical direction, the inclined column of its lower half will slowly approach the inner wall of the other side of the slider seat 6. At this time, the transition groove of the sliding block 7 fits with the protrusion, so that the block drives the slider seat 6 to move, thereby causing the slider seat 6 to pull the slider 6 to one side to achieve the demolding of the slider 6.

[0022] A glue inlet 2 is opened on one side of the surface of the slider 5, and a flow channel 1 can be inserted into the glue inlet 2. The other end of the slider 5 is connected to the mold 3, and the bottom end of the mold 3 is provided with a moving mold side forming part 4.

[0023] During the mold making process, the slurry is injected into the runner 1 and transported to the inlet 2 through the runner. The slurry enters the interior of the slider 5 through the inlet 2 and flows to the mold 3 on one side. At this time, the mold 3 is fixed on the moving mold side forming part 4 by the clamp on the moving mold side forming part 4.

[0024] The transition groove of the sliding block 7 is provided with a buffer part 71. The buffer part 71 is mainly designed as a transition structure with buffer function at the transition groove, such as opening a rounded corner transition structure.

[0025] One end of the slider seat 6 is fixedly connected to the slider seat pressure block 8.

[0026] The tip of the protrusion of the slider seat 6 is provided with a docking part 82, and the end of the protrusion of the slider seat 6 is a sliding surface 81. The height of the sliding surface 81 determines the height of the protrusion of the slider seat 6. When the height of the sliding surface is too high, the distance between the protrusion of the slider seat 6 and the sliding block 7 is too close, making the width of the delay gap 9 too small to ensure that the material head of the inlet can be moved out smoothly. In this embodiment, the optimal height of the sliding surface 81 is 10mm. As the sliding block 7 gets closer to the inner wall of the slider seat 6, its buffer part 71 gradually fits with the docking part 82, preventing direct hard collision between the sliding block 7 and the slider seat 6 during demolding. In long-term use, it can protect the docking stability between the slider seat 6 and the sliding block 7 and increase the service life of the demolding parts.

[0027] When this utility model is used, during the demolding process, the sliding block 7 moves in the vertical direction. At this time, the lower half of the sliding block 7 moves in the delay seam 9 to provide time for the injection port to be pulled out of the slider. When the sliding block 7 is close to the inner wall of the slider seat 6, its buffer part 71 gradually fits with the docking part 82, preventing direct hard collision between the sliding block 7 and the slider seat 6 during the demolding process, thus completing the demolding of the slider 5.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
