Embodiment Construction

[0041] Attached to the following Figure 1-9 This application will be described in further detail.

[0042] The embodiment of the present application discloses an injection mold for a lead screw 1 . refer to figure 2 , the injection mold includes a face plate 2, a stripping plate 3, a plate 4, a plate B 5, a supporting plate 6, a mounting plate 7 and a bottom plate 9, which are arranged in sequence. One side of the plate 7 is provided with a pusher 10 for driving the part of the screw rod body 101 of the lead screw 1 to spiral out of the threaded section. After the product is injection-molded, the A plate 4 and the bottom plate 9 are first opened, and then the pusher 10 will drive the screw rod body 101 of the lead screw 1 to withdraw, so as to achieve damage-free demolding of the thread segment. The specific process is described in detail below.

[0043] like figure 2 , image 3 and Figure 4 As shown, the panel 2 includes the first and second boards that are fixedly...

Abstract

The guide screw injection mold comprises a panel, a stripper plate, a plate A, a plate B, a bearing plate, a mounting plate, an ejector plate and a bottom plate which are sequentially arranged, an injection molding opening communicated with an injection molding channel is formed in the panel, the injection molding channel penetrates through the panel, the stripper plate and the plate A, and a mold sleeve is arranged in the plate B; the top of the die sleeve is provided with inner teeth and a first forming cavity used for forming a gear part of the guide screw, a second forming body provided with inner spiral teeth and used for forming a screw body of the guide screw is arranged in the die sleeve, and the mounting plate is provided with an abutting rod vertically and upwards penetrating through the ejector plate and the bearing plate and fixed to the bottom of the second forming body. An anti-disengaging rod abutting against the bottom of the abutting rod is arranged in the bottom plate, a pushing piece is fixedly arranged on one side of the mounting plate, and a driven piece which is in linkage with the pushing piece and drives the second forming body to rotate is arranged in the mounting plate. The demolding device has the effect of rapidly and stably demolding on the premise that the spiral teeth of the screw body are not damaged.

Description

technical field [0001] The present application relates to the field of injection molds, and in particular, to a lead screw injection mold. Background technique [0002] Lead screws in car door locks, such as figure 1 As shown, it includes a screw rod body 101 with helical teeth and a gear part 102 fixedly connected with one end of the screw rod body 101. The screw rod body 101 coincides with the central axis of the gear part 102, and the screw rod body 101 is away from the gear part 102. There is a non-threaded section, And the screw rod body 101 and the gear part 102 are integrally injection-molded. [0003] In the related art, it is necessary to design and manufacture an injection mold in the process of manufacturing the lead screw. However, due to the existence of the helical teeth of the screw rod body, the traditional direct demolding structure cannot be directly demolded during the demoulding process, otherwise the helical teeth will be damaged. situation occurs. ...
