Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to a rubber vulcanization mold. Background Art

[0002] Rubber vulcanization refers to the process of chemically reacting the raw rubber in the rubber particles with the vulcanizing agent to crosslink the linear macromolecules into three-dimensional macromolecules. It can make the rubber have the characteristics of high strength, high elasticity, high wear resistance and corrosion resistance, and is widely used in various fields. The vulcanization of rubber is usually carried out on a vulcanizer.

[0003] A Chinese patent with announcement number CN219486349U discloses a vulcanized rubber oil seal mold, including a vulcanizer, a first hydraulic rod, a second hydraulic rod and a mold. When used, the first hydraulic rod drives the mold as a whole to move horizontally, so that the mold moves back and forth inside and outside the vulcanizer, and the second hydraulic rod drives the upper mold and the lower mold of the mold to open and close. The specific steps are: the first hydraulic rod takes the mold out of the vulcanizer → the second hydraulic rod moves the upper mold up to complete the mold opening → the operator loads and unloads → the second hydraulic rod moves the upper mold down to complete the mold closing → the first hydraulic rod moves the mold into the vulcanizer.

[0004] In the technical solution of the above patent, operators are prone to fatigue when loading and unloading the mold for a long time, which may lead to negligence at work, improper operation or non-standard operation. When the upper and lower molds of the mold are pressed together, the operators are likely to suffer injuries to their palms. Utility Model Content

[0005] In order to solve the technical problem in the prior art that operators may suffer from palm injuries due to improper operation, the utility model provides a rubber vulcanization mold.

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

[0007] A rubber vulcanization mold comprises symmetrically arranged fixing seats; the fixing seats are all provided with slide grooves; fixing plates are slidably arranged in the slide grooves; a mold body is fixedly arranged on the fixing plates, and the mold body consists of a forming upper mold and a forming lower mold that fit each other; hinge blocks are fixedly arranged on the parts of the mold body corresponding to the forming upper mold and the forming lower mold, and hinge rods are rotatably arranged in the hinge blocks, and the forming upper mold and the forming lower mold are rotatably connected to each other through the cooperation of the hinge blocks and the hinge rods.

[0008] Furthermore, a guide block is fixedly arranged on the fixed seat; a guide groove is opened inside the guide block; a connecting rod is slidably arranged inside the guide groove; a symmetrically arranged connecting head is fixedly connected to one end of the forming upper mold of the mold body away from the hinge block, and the connecting rod is rotatably arranged inside the connecting head.

[0009] Furthermore, a circular limiting plate is provided at one end of the connecting rod; a first nut is threadedly connected to the other end of the connecting rod, and the first nut is composed of a washer and a nut.

[0010] Furthermore, a protrusion is fixedly connected to the lower molding die of the mold body, and the protrusions are symmetrically arranged on both sides of the mold body; a fixing groove is opened on the fixing plate corresponding to the position of the protrusion, and the fixing groove is presented as two straight grooves arranged on both sides of the mold body for fixing the mold body.

[0011] Furthermore, a screw is provided in each of the protrusions, and a second nut is threadedly connected to the screw corresponding to the lower surface of the fixing plate, and the second nut has the same shape as the first nut.

[0012] Furthermore, a plurality of mounting plates are fixedly provided on the lower surface of the fixing seat by screws, and a telescopic rod is fixedly provided on the mounting plates together. A connecting block is fixedly connected to one end of the fixing plate close to the connecting rod, and the connecting block is connected to the output section of the telescopic rod.

[0013] Beneficial effects of the utility model:

[0014] The utility model drives the fixing plate to move the mold body horizontally out of the vulcanizer through the telescopic rod, and the vulcanizer will not cause harm to the operator due to misoperation. Then, since the mold body is connected by the cooperation of the hinge rod and the hinge block, the operator needs to rotate it to realize the opening and closing of the mold body, and then load and unload materials. Compared with the prior art, the mechanized opening and closing mechanism of the vulcanization mold body is cancelled, and the operator will not be crushed when the mold body is closed due to improper operation.

[0015] The utility model can realize automatic opening and closing of the mold body without providing an additional power source through the cooperation of the guide groove, the connecting rod, the hinge block, the hinge rod and the telescopic lever, and since the opening and closing of the molding upper mold and the molding lower mold of the mold body are realized by the horizontal movement of the fixed plate, the mold body will move synchronously when closing. At this time, the palm is in a fixed position and therefore will not be clamped inside the mold body to cause damage to the palm. BRIEF DESCRIPTION OF THE DRAWINGS

Through the cooperation of the circular stopper and the first nut 84, it can be taken out of the guide groove 81 at any time, so that it is convenient for operators to replace different molds.

[0026] Please refer again Figure 1-Figure 2 As shown, a protrusion 9 is fixedly connected to the lower molding die of the mold body 3, and the protrusion 9 is symmetrically arranged on both sides of the mold body 3; a fixing groove 91 is opened on the fixing plate 2 at the position corresponding to the protrusion 9, and the fixing groove 91 is presented as two straight grooves arranged on both sides of the mold body 3, which is used to fix the mold body 3; a screw 92 is arranged in each of the protrusions 9, and the screw 92 is threadedly connected with a second nut 93 corresponding to the lower surface of the fixing plate 2, and the second nut 93 has the same shape as the first nut 84.
