Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a PC alloy injection mold. Background Technology

[0002] Injection molds are specialized tools used in plastic injection molding processes. They are used to inject molten plastic into a mold cavity, which then cools and solidifies to obtain the finished product. They are widely used in the production of plastic parts and products, particularly suitable for mass production of products with complex geometries and high precision requirements, such as automotive parts, electronic casings, home appliances, and toys. Injection molds have a relatively complex structure, with the mold base serving as the foundation and supporting the entire mold structure. The mold base includes a fixed mold platen and a movable mold platen, which are fixed to the moving and fixed mold mounting plates of the injection molding machine, respectively. The fixed and movable mold plates are the core load-bearing components of the mold (especially injection molds and stamping molds). Their cooperation directly determines the formation of the mold cavity and the stability of mold opening and closing. The guide pins fixed to the fixed mold platen and the guide bushings fixed to the movable mold platen are the core components of the mold closing guiding mechanism. Their function is to ensure the coaxiality and parallelism of the fixed and movable mold plates when they close, preventing cavity misalignment.

[0003] Currently, traditional guide posts and guide sleeves are fixed in position, which has the following shortcomings:

[0004] 1. The guide post hole position is strongly tied to the "guiding requirements" of a specific cavity - different brands and models of injection molding machines / presses may have differences in the "mounting hole position of the fixed mold base plate" and the "distribution benchmark of clamping force". The fixed guide post may be unusable due to the mismatch of the positioning benchmark of the new cavity of different models of injection molding machines and presses, and the guide post hole of the fixed mold plate needs to be re-processed.

[0005] 2. After long-term use, the fixed template may deform due to the clamping force, causing the guide post axis to shift. This can lead to problems such as "stuck fit between guide post and guide sleeve" and "cavity misalignment". The moving template needs to be replaced or holes need to be re-drilled, resulting in high maintenance costs.

[0006] Therefore, how to design a PC alloy injection mold that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0007] To address the aforementioned problems, the present invention aims to provide a PC alloy injection mold that solves the issues of fixed positions of existing guide pillars and guide sleeves, which make it difficult to adjust according to the cavity shape installation reference, resulting in poor practical flexibility and high maintenance difficulty.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: including a fixed mold device and a moving mold device that cooperates with the fixed mold device;

[0009] The fixed mold device includes a fixed mold plate, four fixed mold connecting plates respectively movably disposed at the four corners of the fixed mold plate edge, and four sets of first control and movement components respectively fixed to the side wall of the fixed mold plate and disposed between adjacent fixed mold connecting plates; each set of first control and movement components includes two first electric push rods symmetrically fixed to the side wall of the fixed mold plate, a first connecting plate fixed to the protruding end of the first electric push rod for connecting with the fixed mold connecting plate, and several first fastening bolts for connecting the first connecting plate and the fixed mold connecting plate;

[0010] The moving mold device includes a moving mold plate whose inner side mates with the upper surface of the fixed mold plate, four moving mold connecting plates respectively movably disposed at the four corners of the edge of the moving mold plate, and four sets of second control and movement components respectively fixed to the side wall of the moving mold plate and disposed between adjacent moving mold connecting plates; each set of second control and movement components includes two second electric push rods symmetrically fixed to the side wall of the moving mold plate, a second connecting plate fixed to the protruding end of the second electric push rod for connecting with the moving mold connecting plate, and several second fastening bolts for connecting the second connecting plate and the moving mold connecting plate.

[0011] Furthermore, the four corners of the fixed template edge are provided with first connecting grooves that cooperate with the fixed template connecting plate.

[0012] Furthermore, the four corners of the moving template edge are provided with second connecting grooves that cooperate with the moving template connecting plate.

[0013] Furthermore, the upper surface of the fixed mold connecting plate is vertically fixed with guide pillars, and the lower surface of the moving mold connecting plate is provided with guide sleeves for connecting with the guide pillars at the corresponding positions of the guide pillars.

[0014] Furthermore, both the first and second electric push rods have length scale lines on their extension rods for easy observation of the extension length.

[0015] Furthermore, at least two first fastening bolts are provided between each first connecting plate and the fixed mold connecting plate; and at least two second fastening bolts are provided between each second connecting plate and the moving mold connecting plate.

[0016] This utility model has the following beneficial effects:

[0017] 1-This utility model is provided with a fixed mold connecting plate and four sets of first control moving components respectively fixed between adjacent fixed mold connecting plates, a moving mold connecting plate and four sets of second control moving components respectively fixed between adjacent moving mold connecting plates. On the one hand, it is convenient to move the first and second control moving components according to the positioning and installation reference of the cavity shape so that the guide post of the fixed mold connecting plate and the guide sleeve of the moving mold connecting plate can be matched, avoiding conflicts with structures such as inclined guide post core pulling, hot runner and side gate. On the other hand, if the fixed mold plate deforms due to the clamping force after long-term use on any side, causing the axis of the guide post on the fixed mold connecting plate to shift, the controller controls the electric push rod on the corresponding side to move the moving mold connecting plate, and the guide post and guide sleeve are realigned, reducing maintenance costs and improving practicality. By changing the position of the fixed mold connecting plate and the moving mold connecting plate through the first and second control moving components, the practicality and flexibility of use are improved.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0026] See Figure 1-3 As shown, the scheme includes a fixed mold device 1 and a moving mold device 2 that cooperates with the fixed mold device 1;

[0027] The fixed mold device 1 includes a fixed mold plate 11, four fixed mold connecting plates 12 respectively movably disposed at the four corners of the fixed mold plate 11, and four sets of first control and movement components 13 respectively fixed to the side wall of the fixed mold plate 11 and disposed between adjacent fixed mold connecting plates 12; each set of first control and movement components 13 includes two first electric push rods 131 symmetrically fixed to the side wall of the fixed mold plate 11, a first connecting plate 132 fixed to the protruding end of the first electric push rod 131 for connecting with the fixed mold connecting plate 12, and a plurality of first fastening bolts 133 for connecting the first connecting plate 132 and the fixed mold connecting plate 12.

[0028] The moving mold device 2 includes a moving mold 21 whose inner side mates with the upper surface of the fixed mold 11, four moving mold connecting plates 22 respectively movably disposed at the four corners of the edge of the moving mold 21, and four sets of second control moving components 23 respectively fixed to the side wall of the moving mold 21 and disposed between adjacent moving mold connecting plates 22; each set of second control moving components 23 includes two second electric push rods 231 symmetrically fixed to the side wall of the moving mold 21, a second connecting plate 232 fixed to the protruding end of the second electric push rod 231 for connecting with the moving mold connecting plate 22, and several second fastening bolts 233 for connecting the second connecting plate 232 and the moving mold connecting plate 22.

[0029] The upper surface of the fixed template 11 and the lower surface of the moving template 21 are provided with corresponding mold holes according to the actual situation.

[0030] Furthermore, the four corners of the fixed template 11 are provided with first connecting grooves 111 that cooperate with the fixed template connecting plate 12.

[0031] Furthermore, the four corners of the moving template 21 are provided with second connecting grooves 211 that cooperate with the moving template connecting plate 22.

[0032] Furthermore, the upper surface of the fixed mold connecting plate 12 is vertically fixed with guide posts 121, and the lower surface of the moving mold connecting plate 22 is provided with guide sleeve 221 holes for connecting with the guide posts 121 at the corresponding positions of the guide posts 121.

[0033] Furthermore, both the first electric push rod 131 and the second electric push rod 231 have length scale lines 3 on their extension rods for easy observation of the extension length. Ideally, the first electric push rods 131 and 231 of the left and right sides of the first control movement assembly 13 and the second control movement assembly 23 are synchronously driven by the same controller, while the first electric push rods 131 and 231 of the front and rear sides of the first control movement assembly 13 and the second control movement assembly 23 are synchronously driven by another controller.

[0034] Furthermore, at least two first fastening bolts 133 are provided between each first connecting plate 132 and the fixed mold connecting plate 12; at least two second fastening bolts 233 are provided between each second connecting plate 232 and the moving mold connecting plate 22. The two first fastening bolts 133 are symmetrically distributed around the center of the fixed mold connecting plate 12, and the two second fastening bolts 233 are symmetrically distributed around the center of the moving mold connecting plate 22. The number and distribution of the first fastening bolts 133 and the second fastening bolts 233 in this embodiment is one example. In other embodiments, different numbers and distributions of the first fastening bolts 133 and the second fastening bolts 233 can be used, which are not limited here.

[0035] The working principle is roughly as follows:

[0036] The fixed mold plate 11 is installed and fixed on the fixed mold base plate of the injection molding machine or press. The mold holes (positioning holes) of the fixed mold plate 11 and the moving mold plate 21 are aligned and placed parallel to each other. The moving mold plate 21 is then fixed on the moving mold base plate of the equipment. According to the installation reference and positioning reference of the injection molding machine / press, the first electric push rod 131 and the second electric push rod 231 on both sides are driven synchronously to ensure that the guide post 121 on the fixed mold connecting plate 12 and the guide sleeve 221 on the moving mold connecting plate 22 are always aligned. When the mold is closed, the moving mold plate 21 moves closer to the fixed mold plate 11. The two are precisely aligned through the guide post 121 and the guide sleeve 221 to form a closed mold cavity. When the mold is opened, the moving mold plate 21 moves away from the fixed mold plate 11 to achieve product demolding.

[0037] If the fixed mold plate 11 deforms due to the clamping force after long-term use on any side, causing the axis of the guide post 121 on the fixed mold connecting plate 12 to shift, the controller controls the electric push rod on the corresponding side to move, causing the moving mold connecting plate 22 to move, and the guide post 121 and guide sleeve 221 to realign.

[0038] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
