Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a guiding mechanism. Background Art

[0002] Injection molding is a processing method used in mass production of certain parts with complex shapes. The specific principle is: the heated and melted plastic raw material is pushed by the injection molding machine screw under high pressure into the mold cavity of the plastic mold. After cooling and solidification, a plastic molded product is obtained. The plastic mold consists of a movable mold and a fixed mold. The movable mold is installed on the movable template of the injection molding machine, and the fixed mold is installed on the fixed template of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic product.

[0003] The main function of the guide mechanism of the injection mold is to guide, ensure the normal closing and separation of the movable and fixed molds, and avoid collision between the movable and fixed molds. The connection position of the injection mold will produce a strong collision during the mold closing process, which will cause greater wear on the contact surfaces of the upper mold and the lower mold. With the long-term use of the injection mold, the upper and lower molds of the injection mold are prone to abrasive damage, which affects the use of the injection mold. For this reason, we propose an injection mold with a guide mechanism. Utility Model Content

[0004] The main purpose of the utility model is to provide an injection mold with a guide mechanism. The guide mechanism is set by improving the injection upper mold and the injection lower mold of the injection mold. The guide mechanism forms a sliding structure that can guide outside the injection upper mold and the injection lower mold, and the guide rod of the guide mechanism and the corresponding spring, rubber insert and recessed rubber pad and other structures can perform elastic resistance and buffering when the injection upper mold and the injection lower mold are closed, greatly reducing the descending force of the injection upper mold, thereby alleviating the friction force when the injection lower mold and the injection upper mold are closed, effectively avoiding greater friction damage when the injection lower mold and the injection upper mold are closed, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Furthermore, the width between the two sets of limit plates is the same as the width of the guide plate;

[0008] By adopting the above technical solution, the limit plate is clamped on the outside of the guide plate with its own double set of plates to perform vertical guidance before the injection lower mold and the injection upper mold are closed, ensuring that the injection lower mold and the injection upper mold can be guided and closed smoothly.

[0009] Furthermore, the height of the guide plate is higher than the height of the mold body of the lower injection mold;

[0010] By adopting the above technical solution, after the plate body of the guide plate exceeds the lower injection mold, it can cooperate with the limit plate to guide the limit plate over a long distance above the lower injection mold.

[0011] Furthermore, the diameter of the raised disc block of the rubber disc is the same as the diameter of the inner coil of the spring;

[0012] By adopting the above technical solution, the rubber convex disc can be inserted into the spring, so that the spring can provide elastic support at the rubber convex disc above the rubber panel. When the guide rod is pressed on the spring, the bottom of the spring is not easy to swing outside the rubber panel.

[0013] Furthermore, the diameter of the notched rubber pad is the same as the diameter of the disc-shaped plate of the rubber insert;

[0014] By adopting the above technical solution, the rubber panel can be adapted to be inserted into the recessed rubber pad, thereby providing stable support for the rubber panel.

[0015] Furthermore, the rod body diameter of the guide rod is the same as the inner ring hole diameter of the rubber inner resistance ring, and the ring opening diameter of the rubber inner resistance ring is smaller than the ring body diameter of the rubber outer resistance ring;

[0016] By adopting the above technical solution, the guide rod can pass through the rubber resistance ring into the guide hole to compress the spring, and the rubber outer resistance ring is deformed under the action of force to form a multi-stage buffer damping structure through the rubber inner resistance ring, thereby alleviating the friction force when the injection lower mold and the injection upper mold are closed.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

A spring 8, a rubber inlay 7 and a recessed rubber pad 6, and a rubber inlay 7 has a protruding rubber disc 9 on the surface thereof which is inserted into the spring 8, and the rubber inlay 7 is inserted into the pad opening of the recessed rubber pad 6, and guide rods 4 are fixed at four points on the lower mold surface of the injection upper mold 2, and the guide rods 4 are inserted into the rubber inner resistance ring 5, and a rubber outer resistance ring 10 is bonded to the rod body of the guide rod 4, and guide plates 11 are symmetrically fixed to the outside of the mold bases on both sides of the injection lower mold 1, and limiting plates 12 for cooperating with the guide plates 11 for vertical clamping are symmetrically fixed to the outside of the mold bases on both sides of the injection upper mold 2.

[0025] The width between the two sets of limit plates 12 is the same as the width of the guide plate 11.

[0026] By adopting the above technical solution, the limiting plate 12 is clamped on the outside of the guide plate 11 with its own double set of plates to vertically guide the injection lower mold 1 and the injection upper mold 2 before they are closed, ensuring that the injection lower mold 1 and the injection upper mold 2 can be guided and closed smoothly.

[0027] The height of the guide plate 11 is higher than the height of the lower injection mold 1.

[0028] By adopting the above technical solution, after the plate body of the guide plate 11 exceeds the lower injection mold 1 , it can cooperate with the limit plate 12 to guide a longer distance above the lower injection mold 1 .

[0029] The diameter of the raised disc of the rubber convex disc 9 is the same as the diameter of the inner spring coil of the spring 8;

[0030] By adopting the above technical solution, the rubber convex disc 9 can be inserted into the spring 8, so that the spring 8 can provide elastic support at the rubber convex disc 9 above the rubber panel 7. When the guide rod 4 is pressed on the spring 8, the bottom of the spring 8 is not easy to swing outside the rubber panel 7.

[0031] The diameter of the notched rubber pad 6 is the same as the diameter of the disc-shaped plate of the rubber insert 7;

[0032] By adopting the above technical solution, the rubber panel 7 can be adapted to be inserted into the recessed rubber pad 6 , thereby providing stable support for the rubber panel 7 .

[0033] The rod body diameter of the guide rod 4 is the same as the inner ring hole diameter of the rubber inner resistance ring 5, and the ring opening diameter of the rubber inner resistance ring 5 is smaller than the ring body diameter of the rubber outer resistance ring 10;

[0034] By adopting the above technical solution, the guide rod 4 can pass through the rubber resistance ring 5 into the guide hole 3 to compress the spring 8, and the rubber outer resistance ring 10 is deformed under the action of the force to form a multi-stage buffer damping structure through the rubber inner resistance ring 5, thereby alleviating the friction force when the injection lower mold 1 and the injection upper mold 2 are closed.

[0035] It should be noted that the utility model is an injection mold with a guide mechanism. The guide mechanism 13 is set by improving the injection upper mold 2 and the injection lower mold 1 of the injection mold. When the injection upper mold 2 and the injection lower mold 1 are installed at the injection molding equipment for injection molding, the injection upper mold 2 is clamped with a limit plate 12 at the guide plate 11 of the injection lower mold 1, so that the limit plate 12 and the guide plate 11 form a guiding sliding structure, and then the injection upper mold 2 is pressed toward the surface of the injection lower mold 1. At this time, the guide rod 4 of the injection upper mold 2 can pass through the rubber resistance ring 5 of the injection lower mold 1 to enter the guide hole 3 and compress the spring 8, and the rubber outer resistance ring 10 is deformed by the force through the rubber inner resistance ring 11. The resistance ring 5 forms a multi-stage buffer damping structure, and after the guide rod 4 presses down the spring 8, the elastic resistance of the spring 8 and the deformation buffering effect of the rubber insert 7 and the recessed rubber pad 6 can effectively reduce the descending force of the injection upper mold 2, thereby effectively alleviating the friction force when the injection lower mold 1 and the injection upper mold 2 are closed, and avoiding greater friction damage when the injection lower mold 1 and the injection upper mold 2 are closed. After the injection upper mold 2 and the injection lower mold 1 are closed, injection molding can be carried out from the injection port of the injection upper mold 2. When the injection upper mold 2 is pulled away from the top of the injection lower mold 1, the guide rod 4 can detach from the rubber inner resistance ring 5 with the rubber outer resistance ring 10, thereby exposing the injection lower mold 1 for easy removal of the injection plastic.

[0036] It should be noted that the utility model is an injection mold with a guide mechanism. The components in the utility model are all components known to technical personnel in the field, and their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods.
