Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to a demolding mechanism of an anti-adhesion injection mold. Background Technique

[0002] An injection mold is a mold used for plastic injection molding. It can form plastic products with complex shapes, high dimensional accuracy or with inserts in one time. The injection mold is composed of many steel plates and various parts, including a forming device, a positioning device, a cooling system, a constant temperature system, a runner system, etc. The demolding mechanism of the injection mold is an institution that is responsible for pushing out the cooled and solidified plastic parts and the condensate of the gating system from the cavity or core and the runner in the mold during the injection molding process. The main actions of the demolding mechanism include ejection and removal, that is, first loosening and separating the product and the condensate of the gating system from the mold, which is called ejection, and then taking out the ejected object from the mold to ensure that the product is not deformed.

[0003] In the "demolding mechanism of an injection mold" with the publication number of CN219748781U, it includes a main body. Four groups of support columns are arranged at the four corners of the bottom end of the main body. A support frame is arranged at the top end of the main body. A lifting mechanism is arranged at the middle position of the bottom end of the main body. A mold base is arranged at the middle position of the top end of the main body. Condensing mechanisms are arranged on both side walls of the mold base. The lifting mechanism includes a fixed frame. A first electric telescopic rod is arranged at the middle position of the top end of the fixed frame. A limit plate is arranged at the top end of the first electric telescopic rod. Four groups of second electric telescopic rods are arranged at the edge position of the top end of the limit plate. The advantages of the utility model are as follows: it can effectively push out the forming mold, thereby improving the demolding efficiency and convenience. It can quickly cool and form the mold inside the mold base, thereby accelerating the mold forming efficiency.

[0004] When the above-mentioned injection mold demolding mechanism assists the mold injection molding process, basically, the injection mold is quickly demolded through the demolding mechanism. However, the injection mold is prone to mold adhesion due to overheating during the injection molding process, and mold adhesion will occur during the later demolding, which is not convenient for the stable demolding use of the injection mold demolding mechanism in the later stage.

[0005] Therefore, we proposed a demolding mechanism of an anti-adhesion injection mold, which can well solve the above problems. Summary of the Invention

[0006] The purpose of the present utility model is to provide a demoulding mechanism for an injection mould to prevent adhesion, so as to solve the problem proposed in the above background technology that basically in the current market, the injection mould is quickly demoulded through the demoulding mechanism, but the injection mould is prone to adhesion during the injection moulding process due to overheating, and adhesion will occur during the later demoulding, which is not convenient for the stable demoulding use of the injection mould demoulding mechanism in the later stage.

[0007] To achieve the above purpose, the present utility model provides the following technical solution: A demoulding mechanism for an injection mould to prevent adhesion, including a base, with damping rods arranged at both ends of its bottom, and the bottoms of both damping rods are connected with support legs through screws, and the two damping rods are symmetrically arranged about the vertical center line of the base;

[0008] It also includes: a base, with a fuselage installed above it through screws, and a top plate is arranged in a groove at the top of the fuselage, and support rods are installed at both ends of the bottom of the top plate through screws. At the same time, the bottoms of both support rods penetrate and extend to both ends inside the fuselage. The bottoms of the two support rods are connected with a moving plate through screws, and extrusion blocks are arranged at both ends of the top of the moving plate, and the outer sides of the tops of the two extrusion blocks are connected to the inner side walls of the top of the fuselage.

[0009] Preferably, the moving plate is slidably installed through the fuselage, and both ends of the moving plate are connected to the inner wall of the fuselage through extrusion springs. The elastic reset of the moving plate that has been extruded and descended can be achieved through the elastic force of the two extrusion springs themselves. At this time, the position of the top plate that has been extruded and descended can be elastically reset.

[0010] Preferably, limit rods are installed at both ends of the bottom of the moving plate through screws, and the bottoms of both limit rods penetrate and extend to both ends inside the base. Empty grooves are opened on the inner sides of the bottoms of the two limit rods. At the same time, limit blocks are connected inside the two empty grooves. In the base, a pull rod is slidably installed through a reset spring in a groove inside it, and both ends of the pull rod penetrate and are installed with limit blocks, and the structures of the two limit blocks are the same. The elastic reset of the pulled pull rod can be achieved through the reset spring, so that the two limit blocks can be automatically ejected into the empty grooves opened at the bottoms of the two limit rods.

[0011] Preferably, transmission rods are arranged at the bottoms of the two damping rods, and moving seats are slidably installed through grooves at both ends of the transmission rods. The diameter of the moving seats is larger than that of the transmission rods. Swing rods are connected to both sides of the bottom of the base through movable shafts, and both swing rods are inclined. At the same time, the bottoms of the two swing rods are connected with a moving seat through movable shafts. When the base is extruded and descends, the two swing rods can be driven to extrude the two moving seats to slide through the two ends of the transmission rod.

[0012] Preferably, a tension spring is wound around the outside of the transmission rod, and both ends of the tension spring are connected to a moving seat, so that the two moving seats that are squeezed and moved can be elastically reset by the tension spring.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] Support rods are screwed on both ends of the bottom of the top plate, and then a moving plate is screwed on the bottom of the two support rods. When the top plate is squeezed down, the moving plate can be driven to squeeze down, and then the elastic force of the two squeezing springs can be used to elastically reset the squeezing and descending moving plate, so that the squeezing blocks set at the two ends of the top of the moving plate can squeeze and collide with the two ends of the top of the fuselage, and then the mold body above the fuselage can be vibrated and demoulded to avoid the mold sticking to the outer wall of the top plate due to overheating and affecting the subsequent injection molding process;

[0015] Furthermore, limit rods are installed by screws at both ends of the bottom of the moving plate, and then the two limit rods can be driven to extend through the inner ends of the base while the moving plate is extruded and lowered. At this time, the two limit blocks will extend through the bottom ends of the two limit rods to avoid the phenomenon of misalignment and offset of the moving plate after extrusion and lowering, which will affect the subsequent mold injection processing;

[0016] Furthermore, a pull rod is installed by sliding through a reset spring in the internal groove of the base, and then limit blocks are installed at both ends of the pull rod. When the top plate needs to be reset and moved in the later stage, the pull rod can be manually pulled to move the position, and then the limit blocks set at both ends of the pull rod can be driven to move the position, and then the two limit blocks will be separated from the two limit rods, so that the top plate can be automatically reset elastically, which is more time-saving and labor-saving.

[0017] By connecting the supporting legs at both ends of the bottom of the base through damping rods, the two damping rods can be used to increase the overall anti-vibration buffering performance of the fuselage, avoid the fuselage from being damaged by deformation during injection molding, and increase the overall service life of the fuselage;

[0018] Furthermore, swing rods are connected to the two ends of the bottom of the base through movable shafts, and then movable seats are connected to the bottoms of the two swing rods through movable shafts. During the extrusion and injection molding of the fuselage, the two swing rods can be driven to extrude the two movable seats through the movable shafts to move their positions at the two ends of the transmission rod. At this time, the tension spring can elastically reset the two extruded movable seats through its own elastic force, thereby elastically resetting the extruded and lowered base, which is more practical.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides the following technical solutions:

[0029] In the first embodiment, to solve the problem that the existing injection mold is prone to mold sticking due to overheating during injection molding and the problem of mold sticking during demolding in the later stage, it is disclosed that:

[0030] A base 1, with damping rods 2 provided at both ends of its bottom, and the bottoms of the two damping rods 2 are both connected to support legs 3 by screws, and the two damping rods 2 are symmetrically arranged about the vertical center line of the base 1;

[0031] It further includes: a base 1, on which a fuselage 4 is installed by screws, and a top plate 5 is provided with a slot at the top of the fuselage 4, and support rods 6 are installed by screws at both ends of the bottom of the top plate 5. At the same time, the bottoms of the two support rods 6 penetrate and extend to both ends inside the fuselage 4. The bottoms of the two support rods 6 are connected by screws to a moving plate 7, and extrusion blocks 17 are provided at both ends of the top of the moving plate 7, and the outer sides of the tops of the two extrusion blocks 17 are connected to the inner side wall of the top of the fuselage 4.

[0032] The moving plate 7 is slidably installed through the inside of the fuselage 4, and both ends of the moving plate 7 are connected to the inner wall of the fuselage 4 through compression springs 9.

[0033] As Figures 1-6 shown, when the injection mold demolding mechanism performs injection molding on a workpiece, it will drive the top plate 5 to descend in position through the extrusion mechanism. At this time, the support rods 6 provided at both ends of the bottom of the top plate 5 will drive the moving plate 7 to descend in position. When the injection molding is completed, the two compression springs 9 will drive the moving plate 7 to perform elastic reset in position through their own elastic force. Then, the extrusion blocks 17 provided at both ends of the top of the moving plate 7 will squeeze and collide with the inner side of the top of the fuselage 4, and then the mold body above the fuselage 4 can be vibrated and demolded, avoiding the mold from sticking to the outer side wall of the top plate 5 due to overheating and affecting the later injection molding, with better practicability.

[0034] Embodiment 2, different from Embodiment 1, can position and clamp the top plate 5 that is extruded and lowered to avoid loosening and falling off, and discloses:

[0035] Limit rods 8 are installed by screws at both ends of the bottom of the moving plate 7, and the bottoms of the two limit rods 8 penetrate and extend to both ends inside the base 1. At the same time, empty slots are opened on the inner sides of the bottoms of the two limit rods 8, and limit blocks 15 are connected inside the two empty slots. The base 1 is internally provided with a slot and a pull rod 14 is slidably installed through the slot by a return spring 16. Both ends of the pull rod 14 penetrate and are installed with limit blocks 15, and the structures of the two limit blocks 15 are the same.

[0036] As Figures 1-4 shown, while the moving plate 7 is extruded and lowered, the limit rods 8 installed at both ends of its bottom will directly penetrate and extend to both ends inside the base 1. Then, the limit blocks 15 provided at both ends of the pull rod 14 will directly penetrate and extend into the empty slots opened at the bottoms of the two limit rods 8. At this time, the extruded and lowered moving plate 7 can be limited and fixed to avoid misalignment and offset in the later stage, improving the use stability of the injection mold demolding mechanism. Finally, pull the pull rod 14 to drive the two limit blocks 15 to move in position. At this time, the two limit blocks 15 can be separated from the empty slots opened at the bottoms of the two limit rods 8, and then the moving plate 7 can be conveniently elastically reset, so as to facilitate later repeated use.

[0037] Embodiment 3, different from Embodiment 2, the fuselage 4 can be cushioned and shock-absorbed, improving the service life of the fuselage 4, and discloses:

[0038] At the bottom of the two damping rods 2, a transmission rod 13 is provided, and both ends of the transmission rod 13 are slotted and slidably installed with moving seats 11, and the diameter of the moving seats 11 is larger than that of the transmission rod 13. Both sides of the bottom of the base 1 are connected with swing rods 10 through movable shafts, and the two swing rods 10 are both inclined, and the bottoms of the two swing rods 10 are connected with the moving seats 11 through movable shafts. A tension spring 12 is wound and connected to the outside of the transmission rod 13, and both ends of the tension spring 12 are connected with the moving seats 11.

[0039] As Figures 1-7 shown, when the fuselage 4 assists the injection mold in injection molding, the two damping rods 2 can improve the overall seismic cushioning performance of the fuselage 4 through their own elastic forces, avoiding the phenomenon that the fuselage 4 is deformed and damaged due to extrusion and descent. At this time, the swing rods 10 connected to the movable shafts at both ends of the bottom of the base 1 squeeze the two moving seats 11 to move at both ends of the transmission rod 13, and then the elastic force of the tension spring 12 itself can be used to elastically reset the moving seats 11 that are squeezed and moved, improving the overall service life of the fuselage 4.
