Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a guide rail mold. Background Technology

[0002] Molds refer to various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, and die casting. Molds are tools used to make shaped items. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the item by changing the physical state of the material being molded. When producing guide rails, molds are required. Molten raw materials are passed into the mold, cooled and shaped, and the guide rails are produced.

[0003] In the prior art, such as the guide rail production mold proposed in patent application number "CN202320763109.5", the upper mold and the lower mold are connected by a transverse sliding structure. The upper mold and the lower mold can be easily connected and positioned through the lower baffle. The mold is easy to disassemble and assemble. After the guide rail is formed in the mold, the upper mold can be slid off and the forming guide rail at the upper end of the lower mold can be easily removed. Material removal is convenient and very practical.

[0004] In existing technology, molds for producing guide rails generally contain an upper mold and a lower mold. After the upper mold and the lower mold are closed, raw materials are injected and cooled to produce finished products. In order to prevent the upper mold and the lower mold from shifting their positions, multiple positioning pins are often set to guide the upper mold to accurately close onto the lower mold. However, after long-term use, the positioning pins inevitably wear down, resulting in inaccurate positioning and making it impossible to guarantee the positional accuracy when the upper mold and the lower mold are closed, thus reducing the yield of guide rails. Utility Model Content

[0005] The purpose of this utility model is to provide a guide rail mold to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A guide rail mold includes an upper mold and a lower mold. A top plate is fixedly installed on the upper surface of the upper mold, a base is fixedly connected to the bottom surface of the lower mold, and a bottom plate is fixedly connected to the bottom surface of the base. Two limiting rods are fixedly connected to the upper surface of the bottom plate near both sides. Each of the two limiting rods is fitted with a limiting sleeve, and one end of each limiting sleeve is fixedly connected to the upper mold. A plurality of straightening mechanisms are provided on the upper surface of the bottom plate, and a nozzle is fixedly installed on the upper surface of the top plate.

[0008] The correction mechanism includes a fixed frame, which is fixedly installed on the upper surface of the base plate. Slide rods are fixedly installed on both inner side walls of the fixed frame. A slide plate is sleeved between the two slide rods and inside the fixed frame. A correction plate is fixedly connected to the outer side wall of the slide plate.

[0009] Preferably, connecting rods are fixedly connected to both outer side walls of the limiting sleeve, and triangular blocks are fixedly connected to one end of each of the two connecting rods. A slider is fixedly connected to the outer side wall of the correction plate, and the slider and the triangular blocks cooperate with each other.

[0010] Preferably, both slide rods are fitted with support springs, one end of which is fixedly connected to the slide plate, and the other end of which is fixedly connected to the inner wall of the fixed frame.

[0011] Preferably, a connecting block is fixedly installed on the upper surface of the skateboard, and both ends of the connecting block are rotatably connected to a clamping plate via a shaft.

[0012] Preferably, a fixing block is inserted inside the card plate, and the bottom end of the fixing block is fixedly connected to the fixing frame.

[0013] Preferably, the two outer side walls of the fixing block are provided with insertion holes, and a limiting short rod is inserted into each of the two insertion holes. A reset spring is installed between one end of the limiting short rod and the inner wall of the insertion hole.

[0014] Preferably, the inner wall of the limiting sleeve is equipped with a number of ball bearings, and the upper surface of the lower mold and near the four corners are provided with positioning posts, and the bottom end of the positioning posts is fixedly connected to the base.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, during the process of preparing for production by having the upper mold cover the lower mold, each positioning pin can guide and position the upper mold when it is covered by the lower mold to avoid displacement. The limiting sleeve slides along the outside of the limiting rod and guides and positions it at the same time. The triangular block cooperates with the slider to drive the slider to move laterally, so that the straightening plate presses against the outer wall of the upper mold and the lower mold. Similarly, the other straightening plates press against the outer walls of the upper mold and the lower mold at the same time, which can further clamp and straighten the position between the upper mold and the lower mold. This avoids the positioning pins and the limiting rod from being worn and affecting the positioning accuracy, thereby fully ensuring the positional accuracy when the upper mold and the lower mold are covered and improving the yield of the production guide rail.

[0017] 2. In this utility model, by sleeved the card plate outside the fixed block, and with the two limiting short rods and the return spring blocking and limiting the position of the card plate, the position of the connecting block can be further fixed, thereby fixing the position of the straightening plate and preventing the straightening plate from moving under external environmental factors. This improves the stability of the extrusion operation of the upper and lower dies, and thus improves the stability of the position of the upper and lower dies after straightening.

Detailed Implementation

[0028] 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.

[0029] A guide rail mold, such as Figures 1-7 As shown, the system includes an upper mold 3 and a lower mold 4. A top plate 1 is fixedly installed on the upper surface of the upper mold 3. A base 5 is fixedly connected to the bottom surface of the lower mold 4. A base plate 7 is fixedly connected to the bottom surface of the base 5. Two limiting rods 6 are fixedly connected to the upper surface of the base plate 7 near both sides. Limiting sleeves 9 are fitted on the outside of the two limiting rods 6, and one end of each limiting sleeve is fixedly connected to the upper mold 3. Several straightening mechanisms are provided on the upper surface of the base plate 7. A nozzle 2 is fixedly installed on the upper surface of the top plate 1. The straightening mechanism includes a fixed frame 11, which is fixedly installed on the upper surface of the base plate 7. Slide rods 13 are fixedly installed on the two inner side walls of the fixed frame 11. A sliding plate 17 is fitted between the two slide rods 13 and inside the fixed frame 11. A straightening plate 8 is fixedly connected to the outer side wall of the sliding plate 17.

[0030] Connecting rods 20 are fixedly connected to both outer walls of the limiting sleeve plate 9. Triangular blocks 10 are fixedly connected to one end of each connecting rod 20. A slider 18 is fixedly connected to the outer wall of the straightening plate 8, and the slider 18 and the triangular blocks 10 cooperate with each other. Supporting springs are sleeved on the outside of the two sliding rods 13. One end of the supporting spring is fixedly connected to the sliding plate 17, and the other end of the supporting spring is fixedly connected to the inner wall of the fixed frame 11. The triangular block 10 moves vertically downward along one end of the slider 18, which can drive the straightening plate 8 to slide. The sliding plate 17 follows the straightening plate 8 and slides along the outside of the two sliding rods 13, which plays a role in limiting the movement position of the straightening plate 8. When the supporting spring is stretched, the push on the straightening plate 8 is released. Under the action of the rebound force of the supporting spring, the straightening plate 8 can be moved to the initial position, so that the straightening mechanism can be reused.

[0031] The inner wall of the limiting sleeve 9 is equipped with several ball bearings 19. The upper surface of the lower mold 4 and near the four corners are all provided with positioning pins 21, and the bottom of the positioning pins 21 are fixedly connected to the base 5. When the limiting sleeve 9 slides along the outside of the limiting rod 6, each ball bearing 19 moves with the limiting sleeve 9 and rolls along the outer wall of the limiting rod 6. This can reduce the friction between the limiting sleeve 9 and the outer wall of the limiting rod 6, reduce frictional damage to the limiting rod 6, and improve the service life of the limiting rod 6.

[0032] In use, the molten raw material for producing the guide rail is injected into the cavity between the upper mold 3 and the lower mold 4 through the nozzle 2, and left to cool and solidify. During the process of the upper mold 3 closing onto the lower mold 4 and preparing for production, each positioning post 21 can guide and position the upper mold 3 when it closes onto the lower mold 4 to prevent displacement. At the same time, the limiting sleeve 9 slides along the outside of the limiting rod 6, guiding and positioning it. The triangular block 10 connected by the connecting rod 20 moves with the limiting sleeve 9. The inclined surface of the triangular block 10 first contacts one end of the slider 18. The contact plate 18 moves laterally along with the limit plate 9, which in turn moves the straightening plate 8 through the slide plate 17 in conjunction with the fixed frame 11, pressing the outer walls of the upper mold 3 and the lower mold 4. Similarly, the other straightening plates 8 simultaneously press the outer walls of the upper mold 3 and the lower mold 4, which can further clamp and straighten the position between the upper mold 3 and the lower mold 4, preventing the positioning pin 21 and the limit rod 6 from being worn and affecting the positioning accuracy. This ensures the positional accuracy of the upper mold 3 and the lower mold 4 when they are closed, and improves the yield of the production guide rail.

[0033] A connecting block 12 is fixedly installed on the upper surface of the slide plate 17. Both ends of the connecting block 12 are rotatably connected to the clamping plate 14 via shafts. A fixing block 15 is inserted inside the clamping plate 14, and the bottom end of the fixing block 15 is fixedly connected to the fixing frame 11. Insertion holes are opened on both outer side walls of the fixing block 15. A limiting short rod 16 is inserted into each of the two insertion holes. A return spring is installed between one end of the limiting short rod 16 and the inner wall of the insertion hole.

[0034] Specifically, after each straightening plate 8 is pressed tightly against the outer wall of the upper mold 3 and the lower mold 4, the clamping plate 14 is rotated to fit outside the fixing block 15. During the process of fitting the clamping plate 14 outside the fixing block 15, it comes into contact with the smooth surfaces of the two limiting rods 16, which can squeeze the limiting rods 16 and move them into the slot. The return spring is squeezed and contracted. After the paper clamping plate 14 is completely fitted outside the fixing block 15, under the action of the return spring, it can drive one end of the two limiting rods 16 to move out of the slot, blocking and limiting the position of the clamping plate 14, thereby further fixing the position of the connecting block 12 and fixing the position of the straightening plate 8. This prevents the straightening plate 8 from moving under external environmental factors, improves the stability of the pressing operation of the upper mold 3 and the lower mold 4, and thus improves the stability of the position of the upper mold 3 and the lower mold 4 after straightening.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
