Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, in particular to an injection mold for an automobile connector which is easy to demould. Background Art

[0002] An injection mold is a tool for producing plastic products. It consists of a front mold and a back mold that can open and close. When the back mold is closed with the front mold, a product cavity consistent with the product structure is formed between the back mold and the front mold. During injection molding, the heated and molten plastic is injected into the product cavity under high pressure by the injection molding machine. After cooling and solidification, a molded plastic product is obtained.

[0003] The shortcomings of the existing technology: After the injection molding is completed, the existing injection mold cannot cool down quickly due to the high temperature of the molten plastic, and thus cannot solidify and form quickly. The staff needs to wait for it to cool down before taking it out. When taking it out, the cooled plastic easily sticks to the inside of the mold, making it difficult to take it out. Violent removal can cause damage to the molded part, making the work of the staff more difficult. Therefore, an automotive connector injection mold that is easy to demold is proposed. Summary of the Invention

[0004] The purpose of the utility model is to provide an automobile connector injection mold which is easy to demould, so as to solve the existing problems.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an injection mold for an automobile connector which is easy to demold, comprising a workbench, a lower mold being provided on the upper surface of the workbench, an adjusting box being provided on the bottom surface of the workbench, a hollow column being provided on the bottom surface of the inner part of the adjusting box, a first servo motor being provided on the bottom surface of the inner part of the adjusting box, an adjusting screw being rotatably connected in the hollow column, a first bevel gear being sleeved on the bottom end of the peripheral side surface of the adjusting screw, a lifting column being sleeved on the peripheral side surface of the adjusting screw, an output end of the first servo motor passing through one side surface of the hollow column and extending into the hollow column; a second bevel gear being provided at the output end of the first servo motor, the lifting column passing through the bottom surface of the lower mold, a top plate being provided on the upper surface of the lifting column, a cavity being opened on the inner side around the lower mold, and an "S"-shaped threaded tube being sleeved in the cavity.

[0007] Furthermore, a lifting device is provided on the upper surface of the workbench, an adjustment slot is provided on one side of the lifting device, a lifting screw is rotatably connected in the adjusting slot, a slider is provided on the side surface of the lifting screw, a second servo motor is provided on the upper surface of the lifting device, an adjustment plate is provided on one side of the slider, a connecting column is provided on the bottom surface of the adjustment plate, and an upper mold is provided on the bottom surface of the connecting column.

[0008] Furthermore, the upper surface of the workbench is provided with multiple groups of guide rods, and the side surfaces of the multiple groups of guide rods are sleeved with multiple groups of sliding sleeves, and one side of the multiple groups of sliding sleeves is fixedly connected to the two opposite surfaces of the adjustment plate, and the multiple groups of sliding sleeves slide in cooperation with the multiple groups of guide rods. The bottom surface of the workbench is provided with a cooling box, and one side of the workbench is provided with a water pump. A cooling chamber and a return chamber are respectively opened in the cooling box, and a cooling plate is provided on the bottom surface of the cooling chamber and the return chamber. One end of the "S"-shaped threaded pipe is connected to a return pipe, and the other end of the return pipe is fixedly connected to a side of the return chamber. The other end of the "S"-shaped threaded pipe is connected to a drain pipe, and the other end of the drain pipe is fixedly connected to one end of the water pump. The other end of the water pump is fixedly connected to the cooling chamber through a water pipe, and the bottom surface of the cooling box is provided with multiple groups of heat dissipation fins.

[0009] Furthermore, the shape and size of the lifting column are adapted to the hollow column, the lifting column and the hollow column are slidingly matched, the second bevel gear is meshed with the first bevel gear, the reflux pipe is connected to the reflux chamber, the other end of the water pump is connected to the cooling chamber, the cooling chamber is connected to the reflux chamber, a cold enzyme is provided in the cavity, the output end of the second servo motor passes through the upper surface of the lifting device and is fixedly connected to one end of the lifting screw, and the adjusting screw is threaded with the lifting column.

[0010] The utility model has the following beneficial effects:

[0011] The utility model starts the first servo motor to drive the second bevel gear to rotate, and the second bevel gear drives the adjusting screw to rotate by meshing with the first bevel gear. Since the thread groove on the side surface of the adjusting screw cooperates with the thread in the lifting column, the lifting column is driven to rise upward when the adjusting screw rotates, so that the ejector plate can eject the finished mold from the lower mold, making the work simple and quick.

[0012] By setting up a cooling box and cooperating with the cavity, the injection mold can be quickly formed. The water pump is started to extract the coolant from the cooling chamber through the water pipe and send it into the "S"-shaped threaded tube. The coolant in the "S"-shaped threaded tube then takes away the heat and returns the coolant into the return chamber through the return pipe. The coolant returning into the return chamber is hot. The cooling plate then cooperates with the heat dissipation fins to cool the coolant in the return chamber and the cooling chamber. It should be noted that the heat dissipation fins are made of aluminum material, among which aluminum has the advantages of better thermal conductivity and relatively low price.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
