Description

Technical Field

[0001] This utility model relates to the field of machining mold technology, specifically to a machining mold with a hydraulic cylinder slider and an inclined top. Background Technology

[0002] A mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the material being molded. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.

[0003] Molds have specific contours or internal cavity shapes. Applying the contour shape with cutting edges allows the blank to be separated according to the contour line shape, while applying the internal cavity shape allows the blank to obtain a corresponding three-dimensional shape. A search revealed Chinese patent CN208497541U, which discloses a plastic part mold. Both sides of the mold are equipped with mold grooves. Two different types of mold grooves can be designed, or two identical mold grooves can be designed. This not only increases processing capacity but also processing efficiency. Furthermore, a first mold cover and a second mold cover that can slide left and right and be disassembled are installed on the outside of the mold. The first mold cover and the second mold cover can seal the mold. This design makes the mold very easy to disassemble and use, and this combination method greatly facilitates carrying.

[0004] In existing technologies, plastic parts can be removed by separating two molds distributed on the left and right sides. However, when some plastic parts need to be machined with bosses or holes on the outside, it is difficult to directly form these features using only two molds on the left and right sides, resulting in demolding difficulties or even the inability to achieve the desired structure. Based on this, a machining mold with a hydraulic cylinder slider and an inclined top is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a machining mold for a hydraulic cylinder slider with an inclined top, which solves the problem that in the prior art, plastic parts can be removed by separating two molds distributed on the left and right sides. However, when some plastic parts need to be machined with boss pillars or holes on the outside, it is difficult to directly form these features with only two molds on the left and right sides, resulting in demolding difficulties or even the inability to achieve the structure.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A machining mold for a hydraulic cylinder slider with an inclined top, comprising a fixed mold and a moving mold placed left and right. Guide pillars are fixed at the four corners of the fixed mold facing the moving mold. An opening mechanism is provided on the side of the fixed mold facing the moving mold, and a forming mechanism is provided on the opening mechanism, which is synchronously driven by the opening mechanism. The mold opening mechanism includes connecting blocks fixed on the four sides of the fixed mold, four stepped slides opened on the side of the fixed mold facing the moving mold, a sliding component, a limiting strip bolted to the slides, a pad plate fixed in the inner cavity of the connecting blocks on the front and rear sides, a buckle block embedded in the pad plate, and two power drive components. Both the limiting strip and the pad are made of wear-resistant materials.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the moving mold has guide grooves on the side facing the fixed mold that correspond one-to-one with the four guide pillars. The moving mold moves horizontally in a straight line outside the four guide pillars and does not separate from them.

[0009] Through the above technical solution, an upper and lower mold structure is added on the basis of left and right mold splitting. With the cooperation between the upper and lower mold structure and the mold opening mechanism, the processing mold can be separated in multiple directions. This can be used to process plastic parts with holes on the outside and boss pillars, which can effectively solve the molding problem of the outer features of plastic parts and ensure that the plastic parts can be demolded smoothly.

[0010] Furthermore, a core is provided at the center of the fixed mold facing the moving mold, and a cross groove is provided on the side of the moving mold facing the fixed mold.

[0011] The core provided by the above technical solution is a molding die used for processing plastic parts.

[0012] Furthermore, the sliding member includes stepped grooves formed on both sides of the inner cavity of the connecting block, and a first slider slidably connected to the stepped grooves; the stepped grooves and the sliding grooves form a continuous slide to facilitate the movement of the first slider, the limiting strip is located on the upper side of the first slider, and the cross-sectional shape of the first slider is L-shaped.

[0013] The above technical solution ensures that the first slider moves in a straight line, thereby driving the movement of the forming block.

[0014] Furthermore, the two No. 1 sliders have oblique holes on the side near the moving mold, and the other end of the oblique holes passes through the connecting block and extends to the front and rear sides of the fixed mold. The front and rear ends of the moving mold facing the fixed mold are each fixed with an oblique guide rod that slides in the oblique hole.

[0015] The above technical solution allows the two inclined guide rods on the moving mold to slide within the two inclined holes. The movement of the inclined guide rods causes the first sliders on the front and rear sides to move in opposite directions, thereby separating the two molds in the horizontal direction.

[0016] Furthermore, the power drive component includes two hydraulic cylinders fixed on opposite sides of the upper and lower connecting blocks, a second slider slidably connected to the upper and lower sliding grooves and stepped grooves, and a linkage component.

[0017] The above technical solution allows for the separation of two molds in the vertical direction by driving two hydraulic cylinders, thus enabling rapid mold opening.

[0018] Furthermore, the linkage includes three positioning blocks fixed on the upper and lower sliding grooves, the same moving block slidably connected to the opposite sides of the three positioning blocks, and a T-shaped groove formed on the opposite sides of the two second sliders.

[0019] The T-shaped groove provided by the above technical solution facilitates the entry of the piston end of the hydraulic cylinder, thereby making it easier for the operator to fix the piston end.

[0020] Furthermore, the output shaft of the hydraulic cylinder extends through the connecting block into the inner cavity of the T-shaped groove, and the moving block is engaged with the second slider.

[0021] By fixing the piston end of the hydraulic cylinder to the inner cavity of the T-shaped groove using the above technical solution, the movement of the second slider can be pushed by the extension of the piston end of the hydraulic cylinder.

[0022] Furthermore, the forming mechanism includes four forming blocks that are respectively fixed to the opposite side of the two No. 1 sliders and the two No. 2 sliders by bolts. The four forming blocks can form a closed loop assembly and a protrusion is fixed in the middle of the opposite side.

[0023] The above technical solution allows the four molding blocks to separate the processing mold in multiple directions, thereby enabling the molding of special features on some plastic parts.

[0024] Furthermore, the four molding blocks each have an arc surface on one side, and the dimensions of the cross groove cavity are adapted to the dimensions of the molding mechanism when forming a closed-loop structure.

[0025] The above technical solution allows the cross groove to facilitate the moving mold covering the molding mechanism, ensuring a tight fit between the moving mold and the fixed mold.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. By setting the molding mechanism, an upper and lower mold structure is added on the basis of left and right mold splitting. With the cooperation between the mold opening mechanism, the processing mold can be separated in multiple directions. It can be used to process plastic parts with holes on the outside and boss pillars. It can effectively solve the molding problem of the outer features of plastic parts and ensure that the plastic parts can be demolded smoothly. 2. Move the moving mold to the side away from the fixed mold. The two inclined guide rods on the moving mold slide in the two inclined holes. The movement of the inclined guide rods can make the first slider on the front and rear sides move in opposite directions, thereby separating the two molds in the horizontal direction. Then, driven by the two hydraulic cylinders, the two molds in the vertical direction can be separated, so that the mold can be opened quickly and the plastic parts can be automatically unloaded, ensuring the processing efficiency of the plastic parts.

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0031] Example: Reference Figure 1 and Figure 2A machining mold for a hydraulic cylinder slider with an inclined top includes a fixed mold 1 and a moving mold 2 placed left and right. Guide pillars 3 are fixed at the four corners of the fixed mold 1 facing the moving mold 2. An opening mechanism 4 is provided on the side of the fixed mold 1 facing the moving mold 2. A forming mechanism 5 is provided on the opening mechanism 4 and is synchronously driven by the opening mechanism 4.

[0032] Among them, the moving mold 2 has guide grooves on the side facing the fixed mold 1 that correspond one-to-one with the four guide pillars 3. The moving mold 2 moves horizontally in a straight line on the outside of the four guide pillars 3 and does not separate from each other. The fixed mold 1 has a core at the center of the side facing the moving mold 2, and the moving mold 2 has a cross groove on the side facing the fixed mold 1.

[0033] In addition, when the moving mold 2 is in use, the fixed mold 1 is in contact with the moving mold 2, and the plastic raw material can be added into the molding cavity through the feed hole on the right side of the moving mold 2, so that the plastic processed part is formed in the mold cavity.

[0034] refer to Figure 3 , Figure 4 and Figure 5 The mold opening mechanism 4 includes connecting blocks 41 fixed on the four sides of the fixed mold 1, four stepped slide grooves 42 opened on the side of the fixed mold 1 facing the moving mold 2, sliding parts, limiting strips 43 bolted to the slide grooves 42, pads 44 fixed in the inner cavity of the connecting blocks 41 on the front and rear sides, snap-fit ​​blocks 45 embedded in the pads 44, and two power drive parts; the limiting strips 43 and the pads 44 are both made of wear-resistant materials. Using wear-resistant materials can protect their service life and prevent the surface of the limiting strips 43 and the pads 44 from cracking or breaking due to long-term friction; the snap-fit ​​blocks 45 are existing structures and will not be described in detail here.

[0035] The sliding component includes stepped grooves 46 formed on both sides of the inner cavity of the connecting block 41, and a first slider 47 slidably connected to the stepped grooves 46. The stepped grooves 46 and the sliding grooves 42 form a continuous slide to facilitate the movement of the first slider 47. The limiting strip 43 is located on the upper side of the first slider 47. The cross-sectional shape of the first slider 47 is L-shaped. The buckle block 45 can position the first slider 47 when it slides to the buckle block 45.

[0036] In addition, the two sliders 47 have oblique holes on the side near the moving mold 2. The other end of the oblique hole passes through the connecting block 41 and extends to the front and rear sides of the fixed mold 1. The front and rear ends of the moving mold 2 facing the fixed mold 1 are each fixed with an oblique guide rod 6 that slides in the oblique hole.

[0037] In use, after molding, the moving mold 2 can be moved to the right. The movement of the moving mold 2 will drive the two inclined guide rods 6 fixed on it to move. At this time, the inclined guide rods 6 will move in the inclined hole, which will drive the two first sliders 47 to move in opposite directions. The movement of the two first sliders 47 will drive the two molding blocks 51 to move in opposite directions respectively.

[0038] In this embodiment, the power drive component includes two hydraulic cylinders 48 fixed on opposite sides of the upper and lower connecting blocks 41, a second slider 49 slidably connected to the upper and lower sliding grooves 42 and the stepped groove 46, and a linkage component.

[0039] The linkage includes three positioning blocks 410 fixed on the upper and lower sliding grooves 42, the same moving block 411 slidably connected to the opposite sides of the three positioning blocks 410, and a T-shaped groove 412 opened on the opposite side of the two second sliders 49. The piston end of the hydraulic cylinder 48 is inserted into the inner cavity of the T-shaped groove 412 and fixed, so that the piston end of the hydraulic cylinder 48 is fixed to the second slider 49. Then, the second slider 49 can be driven to move up and down by the extension or shortening of the piston end of the hydraulic cylinder 48.

[0040] It should be noted that the piston end of the hydraulic cylinder 48 extends through the connecting block 41 into the inner cavity of the T-shaped groove 412, and the moving block 411 is engaged with the second slider 49.

[0041] In addition, based on the left and right mold splitting, an upper and lower mold structure is added. With the cooperation of two inclined guide rods 6 and power drive components, the processing mold can be separated in multiple directions. At this time, the plastic processing part can be automatically unloaded, which can be used to process and mold plastic processing parts with holes on the outside and boss pillars, ensuring smooth demolding.

[0042] refer to Figure 6 The molding mechanism 5 includes four molding blocks 51 that are fixed to the opposite side of two first sliders 47 and two second sliders 49 by bolts. The four molding blocks 51 can form a closed loop assembly and a protrusion 52 is fixed in the middle of the opposite side. The protrusion 52 can be used to form grooves on plastic parts.

[0043] Among them, the opposite side of each of the four forming blocks 51 is an arc surface, and the size of the cross groove cavity is adapted to the size of the forming mechanism 5 when forming a closed-loop structure.

[0044] In use, the two hydraulic cylinders 48 are activated, and the piston ends of the two hydraulic cylinders 48 shorten, which can drive the two second sliders 49 to move in opposite directions. At this time, the movement of the second sliders 49 drives the upper and lower forming blocks 51 to move in opposite directions. The movement of the second sliders 49 synchronously drives the moving block 411 that is engaged with it to move, so that the moving block 411 slides on the three positioning blocks 410 until it slides to the end. At this time, the four forming blocks 51 are completely separated, and the formed plastic part can fall automatically, which is convenient for the plastic part to be taken out.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
