Description

Technical Field

[0001] This utility model relates to an injection mold, and more particularly to a mold for slanted guide post clearance. Background Technology

[0002] Plastic injection molds are tools used to produce plastic products and have a wide range of applications. For example... Figure 1 As shown, since the plastic product 100 has an insert 101, the insert 101 is suspended in the cavity. Before injection molding, the insert 101 needs to be positioned to prevent it from shifting or deforming during injection molding. If a traditional inclined guide post and slider structure is used, the inclined guide post and slider will interfere with each other and cannot be used. Utility Model Content

[0003] The purpose of this invention is to provide a slanted guide post relief mold with the functions of manually pushing the slider seat inward and driving the slider seat outward with a lever.

[0004] To achieve the above objectives, the technical solution of this utility model is:

[0005] This utility model is a slanted guide post relief mold, including a fixed template, a moving template, a toggle rod, a slider seat, a slider, a slider insert, a movable pin, a pin spring, and a plug;

[0006] The fixed template and the moving template are joined together. The upper end of the actuating rod is fixed on the fixed template, and the lower part of the actuating rod is inserted into the guide groove on the outside of the slider seat. The slider seat slides on the moving template, and the outer end of the slider is fixed on the slider seat. The outer end of the slider insert is connected to the inner end of the slider. The inner end of the slider insert extends into the cavity and is sleeved with the insert of the plastic product. The movable pin is movably inserted into the transverse hole on the outside of the slider seat, and the moving direction of the movable pin is perpendicular to the moving direction of the slider seat. The needle spring is sleeved in the transverse hole on the outside of the slider seat, and the two ends of the needle spring abut against the inner end of the movable pin and the plug fixed on the transverse hole of the slider seat, respectively. The outer end of the movable pin passes through the slider seat and can abut against the actuating rod.

[0007] The lower side wall of the lever has symmetrically arranged inclined surfaces that can abut against the end of the movable needle.

[0008] The outer end of the movable needle has a chamfer so that it abuts against the inclined surface at the bottom of the lever.

[0009] After adopting the above solution, since this utility model includes a fixed template, a moving template, a deflecting rod, a slider seat, a slider, a slider insert, a movable pin, a pin spring, and a plug, after the insert is placed into the cavity, the slider seat, slider, and slider insert, which are fixed together, need to be manually pushed in so that the positioning hole on the slider insert can be sleeved on the outer end of the insert. At the initial mold closing, the lower part of the deflecting rod is inserted into the guide groove of the slider seat, and the lower inclined surface of the deflecting rod will push the movable pin and press the movable pin into the horizontal hole on the outside of the slider seat. Further mold closing, the lower part of the deflecting rod moves inward and is offset from the movable pin. The movable pin is pushed out under the action of the pin spring and abuts against the lower outer side of the deflecting rod. When the mold is opened, the deflecting rod can drive the slider seat to move outward through the movable pin to realize the demolding of the slider insert. It has the functions of manually pushing the slider seat inward and driving the slider seat outward with the deflecting rod.

[0018] like Figures 1-4 As shown, this utility model is a slanted guide post relief mold, including a fixed template 1, a movable template 2, a toggle rod 3, a slider seat 4, a slider 5, a slider insert 6, a movable pin 7, a pin spring 8, and a plug 9.

[0019] The fixed template 1 and the movable template 2 are joined together. The upper end of the actuating rod 3 is fixed on the fixed template 1, and the lower part of the actuating rod 3 is inserted into the guide groove 41 on the outside of the slider seat 4. The slider seat 4 is slidably connected to the movable template 2. The outer end of the slider 5 is fixed on the slider seat 4. The outer end of the slider insert 6 is connected to the inner end of the slider 5. The inner end of the slider insert 6 extends into the cavity and is sleeved with the insert 101 of the plastic product 100. The movable pin 7 is movably inserted into the transverse hole 42 on the outside of the slider seat 4, and the moving direction of the movable pin 4 is perpendicular to the moving direction of the slider seat 4. The pin spring 8 is sleeved in the transverse hole 42 on the outside of the slider seat 4, and the two ends of the pin spring 8 abut against the inner end of the movable pin 7 and the plug 9 fixed on the transverse hole 42 of the slider seat 4, respectively. The outer end of the movable pin 7 passes through the slider seat 4 and can abut against the actuating rod 3.

[0020] The lower side wall of the actuating lever 3 has symmetrically arranged inclined surfaces 31, which can abut against the end of the movable needle 7.

[0021] The outer end of the movable needle 7 has a chamfer so that it abuts against the inclined surface 31 at the bottom of the lever 3.

[0022] The working principle of this utility model:

[0023] like Figures 5-7 As shown, insert 101 is placed into the cavity. Before injection molding, the slider seat 4, slider 5, and slider insert 6, which are fixed together, are manually pushed in together so that the positioning hole on the slider insert 6 can be fitted onto the outer end of insert 101 to position insert 101. At the initial mold closing, the lower part of the actuating rod 3 is inserted into the guide groove 41 of slider seat 4, and the lower inclined surface 31 of the actuating rod 3 pushes the movable pin 7, pressing the movable pin 7 into the horizontal hole 42 on the outside of slider seat 4. Further mold closing, the lower part of the actuating rod 3 moves inward and is offset from the movable pin 7. The movable pin 7 is ejected under the action of the pin spring 8 and abuts against the lower outer side of the actuating rod 3. When the mold opens, the actuating rod 3 can drive the slider seat 4 to move outward through the movable pin 7, realizing the demolding of slider insert 6. This utility model can realize the functions of manually pushing slider seat 4 inward and driving slider seat 4 outward with actuating rod 3.

[0024] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
