AI Technical Summary
During the release process of existing injection molds, due to the depth of the line forming adhesive cavity, there is a risk of sticking to the product. In order to avoid the stroke of the core pulling line, a large cavity needs to be opened in the line insert structure, resulting in a decrease in strength.
A new type of line position top block mold is designed, and the fixed block structure is used to replace the traditional thimble plate. The line position insert slides along the inclined direction and is fixedly arranged at the lower template. The thimble member is fixedly arranged, and the lower template and thimble are fixedly arranged by fixing the block. The parts are connected, and the row insert has a row cavity at the fixed block. The fixed block is located at the lower end of the cavity before demolding, and is located at the upper end after demolding, so as to avoid excessive hollowing of the inside of the row insert.
The structural strength of the line insert is improved, the risk of product sticking during demolding is avoided, and there is no need to set a cavity containing the thimble plate in the insert, maintaining the internal strength of the insert.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to a novel sliding top block mold. Background Art
[0002] The injection mold needs to be demolded after the injection molding is completed. For molds with a large inclination angle between the core pulling direction of the glue position and the horizontal plane, there is a risk of sticking to the slide due to the deep slide molding glue position cavity. At this time, demolding usually requires the use of an ejector structure to eject the product. In a conventional mold structure, the ejector is fixed at the ejector plate, and the ejector plate is fixed in the slide insert. A space that can accommodate the ejector plate needs to be opened in the slide insert. In addition, in order to avoid the stroke of the core pulling slide, the structure of the slide insert needs to open a larger cavity, resulting in a reduction in the structural strength of the slide insert. To this end, we proposed a new slide ejector block mold. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and provide a novel slide top block mould.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of slide block mold, including a lower template, a slide insert, and an ejector pin. The slide insert is slidably arranged at the lower template along an inclined direction, the ejector pin is fixedly arranged, the slide insert is slidably arranged relative to the ejector pin, a fixed block is connected between the ejector pin and the lower template, one end of the fixed block is fixedly connected to the lower template, and the other end of the fixed block is fixedly connected to the ejector pin, the slide insert is provided with a slide cavity at the fixed block; before the product is demolded, the fixed block is located at the lower end of the slide cavity; after the product is demolded, the fixed block is located at the upper end of the slide cavity.
[0005] It is further explained that the lower end of the ejector member is fixedly connected to the fixed block member, and the upper end of the ejector member is fixedly provided with an ejector block for ejecting the product from the slide insert.
[0006] It is further explained that the fixing block is L-shaped, and the lower end of the fixing block is inserted into the lower template and is screwed to the lower template.
[0007] It is further explained that a screw installation groove is opened at the lower end of the slide cavity, and the inclination angle of the screw installation groove is the same as the inclination angle of the slide insert at the lower template.
[0008] It is further explained that the ejector pin is connected to the fixing block via a locking pin screw, and the length of the screw mounting groove is longer than the length of the locking pin screw.
[0009] The beneficial effect of the utility model is that the utility model adopts a structural design of a fixed block to replace the traditional ejector plate structure. The slide insert only needs to be provided with a corresponding fixed block at the corresponding position of each ejector part, and there is no need to open a cavity for accommodating the ejector plate in the slide insert, thereby avoiding the interior of the slide insert being too hollowed out and resulting in reduced strength.

[0015] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.
[0016] Combined with Figure 1 To Attachment Figure 4 As shown, a new type of slide block mold includes a lower template 10, a slide insert 20, and an ejector part 30. The slide insert 20 is slidably set at the lower template 10 along the inclined direction. The slide insert 20 is slidably set relative to the ejector part 30. When the slide insert 20 moves downward along the inclined direction, the ejector part 30 remains fixed relative to the slide insert 20, thereby ejecting the product 70 that has been injected at the slide insert 20, thereby achieving demolding.
[0017] Combined with Figure 1 To Attachment Figure 3 As shown, a fixed block 40 is connected between the ejector member 30 and the lower template 10, one end of the fixed block 40 is fixedly connected to the lower template 10, and the other end of the fixed block 40 is fixedly connected to the ejector member 30, as shown in the attached Figure 2As shown, the slide insert 20 is provided with a slide cavity 21 at the fixed block 40; before the product is demoulded, the fixed block 40 is located at the lower end of the slide cavity 21; after the product is demoulded, the fixed block 40 is located at the upper end of the slide cavity 21. The setting of the fixed block 40 replaces the structural design of the traditional ejector plate. The slide insert 20 only needs to set a corresponding fixed block 40 at the corresponding position of each ejector 30, and there is no need to open a cavity in the slide insert 20 to accommodate the ejector plate, so as to avoid the slide insert 20 being too hollowed out and causing the strength to be reduced.
[0018] Combined with Figure 3 and attached Figure 4 As shown in FIG. 1 , the lower end of the ejector 30 is fixedly connected to the fixed block 40, and the upper end of the ejector 30 is fixedly provided with an ejector block 50 for ejecting the product from the slide insert 20. The fixed block 40 is L-shaped, and the lower end of the fixed block 40 is inserted into the lower template 10 and is screwed to the lower template 10. Figure 3 As shown, after the injection molding is completed, the product 70 needs to be ejected. At this time, the slide insert 20 does not tilt downward relative to the lower mold plate 10. In the process of ejecting the product 70, as shown in the attached Figure 4 As shown, the slide insert 20 is tilted downward relative to the lower template 10, and the ejector member 30 is in a fixed state relative to the slide insert 20. At this time, the product 70 is in an ejected state relative to the slide insert 20, and the ejector block 50 at the ejector member 30 supports the product 70, and the slide insert 20 and the product 70 are separated from each other, thereby achieving demolding.
[0019] Combined with Figure 2 and attached Figure 3 As shown, a screw installation slot 22 is provided at the lower end of the slide cavity 21, and the inclination angle of the screw installation slot 22 is the same as the inclination angle of the slide insert 20 at the lower template 10. The ejector 30 is connected to the fixed block 40 by a locking screw 60, and the length of the screw installation slot 22 is longer than the length of the locking screw 60. When debugging the mold, the screw installation slot 22 can be used to adjust the connection tightness between the locking screw 60 and the ejector 30.
