Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a linear guide rail for a mold clamping mechanism and an injection molding equipment. Background Technology

[0002] In injection molding equipment, the linear guide rail of the mold clamping mechanism needs to withstand the reciprocating motion of the moving mold. Traditional linear guide rails typically use an integrated sliding block. However, this structure has the following problems: High precision dependence: The machining accuracy requirements for the mold and guide rail are extremely high; otherwise, misalignment during mold closing can easily lead to jamming or wear. Lack of self-adjustment: After long-term use, the integrated sliding block requires manual intervention to adjust for deviations caused by wear or deformation, affecting production efficiency. High maintenance costs: When the sliding block is partially damaged, the entire block needs to be replaced, increasing maintenance costs. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a linear guide rail for a mold clamping mechanism and an injection molding equipment, in which the movable mold on the sliding part can float relative to each other during mold closing to automatically correct alignment deviations.

[0004] To address the aforementioned technical problems, this utility model provides a linear guide rail for a mold-locking mechanism in a first aspect. The linear guide rail is used to transport the movable mold of the mold-locking mechanism and includes: a fixed track; a sliding member comprising a first sliding portion and a second sliding portion separately disposed therefrom, the first sliding portion being fixedly connected to the movable mold, and the second sliding portion being slidably connected to the fixed track; and a connecting assembly comprising a first connecting member and a second connecting member, the first connecting member being used to connect the first sliding portion and the second sliding portion in a horizontal direction, and providing a horizontal gap between the first sliding portion and the second sliding portion in a horizontal direction; the second connecting member being used to connect the first sliding portion and the second sliding portion in a vertical direction, and providing a vertical gap between the first sliding portion and the second sliding portion in a vertical direction.

[0010] As an improvement to the above solution, the width of the vertical gap is 0.1mm~0.8mm.

[0011] As an improvement to the above solution, a slider is provided at the bottom of the second sliding part, and a sliding groove is provided on the slider. The second sliding part is slidably connected to the fixed track through the sliding groove; a self-lubricating material layer is embedded in the sliding groove. As an improvement to the above solution, the connecting surface of the first sliding part and the second sliding part is provided with anti-slip texture.

[0012] In a second aspect, this utility model provides an injection molding device, including a movable mold and the linear guide rail, wherein the movable mold is connected to the linear guide rail.

[0013] The beneficial effects of implementing this utility model are as follows: The linear guide rail of the mold-locking mechanism in this utility model features a split sliding component, allowing the first sliding part to float horizontally and vertically relative to the second sliding part. During mold closing, the movable mold on the first sliding part can float relative to it to automatically correct alignment deviations and improve mold closing accuracy.

At the same time, it eliminates the need for strict matching of the machining accuracy of the mold and the guide rail, reducing production costs and improving machining tolerance. Furthermore, the split structure of the sliding component supports partial replacement, making maintenance convenient and avoiding overall scrapping. Attached Figure Description

The linear guide rail includes: a fixed track 100; a sliding member 200, including a first sliding part 210 and a second sliding part 220 separately disposed, the first sliding part 210 being fixedly connected to the movable mold, and the second sliding part 220 being slidably connected to the fixed track 100; a connecting assembly, including a first connecting member 310 and a second connecting member, the first connecting member 310 being used to connect the first sliding part 210 and the second sliding part 220 in the horizontal direction, and providing a horizontal gap between the first sliding part 210 and the second sliding part 220 in the horizontal direction; the second connecting member being used to connect the first sliding part 210 and the second sliding part 220 in the vertical direction, and providing a vertical gap between the first sliding part 210 and the second sliding part 220 in the vertical direction. By setting a split sliding component 200, the first sliding part 210 can float in the lateral and longitudinal directions relative to the second sliding part 220. When the mold is closed, the movable mold on the first sliding part 210 can float relative to it to automatically correct the alignment deviation and improve the mold closing accuracy. The gap design between the first sliding part 210 and the second sliding part 220 buffers the impact force and reduces the hard friction between the sliding component 200 and the track. At the same time, it is not necessary to strictly match the machining accuracy of the mold and the guide rail, which reduces the production cost and improves the machining tolerance. In addition, the split structure of the sliding component 200 supports partial replacement, which is convenient for maintenance and avoids the scrapping of the whole component.

[0018] See Figure 1 Furthermore, in this embodiment, the connection between the first sliding part 210 and the second sliding part 220 forms at least one horizontal first connecting hole, and the first connecting member 310 is disposed in the first connecting hole and is in clearance fit with the first connecting hole.

[0019] See Figure 2 Furthermore, in this embodiment, the first connector 310 is a cylindrical limiting pin that passes through the first connecting hole. Specifically, the end radii of the cylindrical pin are larger than the middle radius, and the first connecting hole has grooves on both sides that mate with the cylindrical pin; the floating range of the horizontal gap is adjusted by the length and diameter of the middle part of the limiting pin.

[0020] Preferably, there are 3 to 5 first connectors 310 to ensure the stability of the connection between the first sliding part 210 and the second sliding part 220.

[0021] Furthermore, in this embodiment, the connection between the first sliding part 210 and the second sliding part 220 forms at least one vertical second connecting hole, and the second connecting member is disposed in the second connecting hole and is in clearance fit with the second connecting hole.

[0022] Furthermore, in this embodiment, the second connector is a pin, which is inserted into the second connecting hole.

[0023] Preferably, the pin is a tapered pin, and the diameter of the second connecting hole is greater than the maximum outer diameter of the pin to form the vertical gap; the floating range of the vertical gap is adjusted by the taper of the pin.

[0024] Preferably, the width of the horizontal gap is 0.1mm to 1mm. The width of the vertical gap is 0.1mm to 0.8mm.

[0025] See Figure 1 Furthermore, in this embodiment, the bottom of the second sliding part 220 is provided with a slider 221, and the slider 221 is provided with a sliding groove. The second sliding part 220 is slidably connected to the fixed track 100 through the sliding groove; the sliding groove is embedded with a self-lubricating material layer.

[0026] Preferably, the sliding groove 221 is provided with 3 to 5 grooves.

[0027] Furthermore, in this embodiment, the connecting surfaces of the first sliding part 210 and the second sliding part 220 are provided with anti-slip textures, which ensures the stability of the connection while the first sliding part 210 and the second sliding part 220 can float relative to each other.

[0028] In a second aspect, this invention provides an injection molding machine. The mold-locking mechanism of the injection molding machine includes a movable mold and a locking mold. The movable plate 400 of the movable mold is connected to the first sliding part 210 of the linear guide rail. The movable mold slides on the linear guide rail until it closes with the locking mold. By setting a split sliding member 200, the movable mold on the sliding member 200 can float relative to the locking mold during mold closing to automatically correct alignment deviations and improve mold closing accuracy.

[0029] As can be seen from the above, the linear guide rail of the mold-locking mechanism in this utility model, by setting a split sliding part, allows the first sliding part to float in the lateral and longitudinal directions relative to the second sliding part. When the mold is closed, the movable mold on the first sliding part can float relative to it to automatically correct the alignment deviation and improve the mold closing accuracy. The gap design between the first sliding part and the second sliding part buffers the impact force and reduces the hard friction between the sliding part and the rail. At the same time, it does not require strict matching of the machining accuracy of the mold and the guide rail, which reduces the production cost and improves the machining tolerance. In addition, the split structure of the sliding part supports partial replacement, which is convenient for maintenance and avoids the scrapping of the whole.

[0030] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
