Description

Technical Field

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

[0002] Injection mold is a device used for mass production of plastic products. The heated and melted plastic is injected into the mold cavity by the injection molding machine under high pressure. After cooling and solidification, the molded product can be obtained. Using injection molds to produce terminal blocks is a mature existing technology. Figure 8 As shown, the third guide insert of the front mold is used to automatically guide the terminal body during mold closing. The advantage of this structure is that the terminal body is automatically blanked and placed smoothly. However, the disadvantages are poor guiding effect, easy mold pressure, and the third guide insert can easily flip the product during mold opening, giving the illusion that the product is sticking to the front mold, causing product deformation and affecting product quality. Therefore, a mold with a guide device is proposed. Utility Model Content

[0025] Working principle: When using the utility model, the first guide insert 15 and the second guide insert 16 on the rear mold 1 are used to position the terminal body 6. Compared with using the third guide insert 5 on the front mold 4 to position the terminal body 6, it can avoid the product sticking to the front mold 4 when opening the mold, and can also avoid the product from being deformed, thereby affecting the position accuracy; at the same time, one of the solenoid valves 23 is opened after the mold is opened, so that compressed air is delivered to the airway 21, pushing the slider 31 to slide up along the limit hole 14 and compressing the spring 36. This process is buffered by the spring 36, and the slider 31 drives the push plate 37 through the connecting rod 35. The push plate 37 lifts the product to realize automatic demoulding. After the demoulding is completed and the material is taken out, the solenoid valve is closed. The magnetic valve 23 starts another electromagnetic valve 23, and the air pressure in the airway 21 returns to normal. Under the elastic action of the spring 36, the slider 31 slides down and resets, and is buffered and vibration-reduced by the rubber pad 33; wherein, the terminal groove 11 is used to accommodate the terminal body 6, the first mounting groove 12 and the first through groove 38 are used to install the first guide insert 15, the second mounting groove 13 and the second through groove 39 are used to install the second guide insert 16, and the first sealing ring 24 is used to improve the sealing between the base 2 and the rear mold 1.
