Problems solved by technology

[0004] Among the above three methods, the influence of adjusting the molding parameters on the torque value is very limited, but to adjust the thread size or surface properties of the lens base or lens barrel mold, it is necessary to design a variety of lens base molds or lens barrel molds according to needs, and In the traditional lens base mold or lens barrel mold, in order to process the lens base or lens barrel with different threads, it is necessary to process thread molds with different threads, and then according to the products to be processed, during the processing Replace the threaded mold to process products that meet the requirements, which increases the cost of mold processing, thereby increasing the processing cost of the lens holder and lens barrel

Embodiment Construction

[0011] Referring to the accompanying drawings, the present invention will be further described by taking the threaded mold for processing the lens barrel as an example.

[0012] Such as figure 1 As shown, the lens barrel 10 is cylindrical, and its outer surface is provided with threads so that the lens barrel 10 can be screwed into a corresponding lens holder (not shown).

[0013] The threaded mold is used in conjunction with a male mold 30 , a female mold 40 and an insert 50 to process the above-mentioned lens barrel 10 . In this embodiment, the thread mold is a sleeve 20 with internal threads.

[0014] The sleeve 20 is disposed in the male mold 30 , and the insert 50 is disposed in the sleeve 20 and can slide relative to the sleeve 20 . A first cavity 43 is defined in the master mold 40 .

[0015] The sleeve 20 includes a main body 21 and a threaded portion 23 detachably mounted on the top of the main body 21 .

[0016] Both the main body portion 21 and the threaded port...

Abstract

A threaded mold comprises a main body part and a thread part arranged on the main body part, wherein at least one sliding chute is arranged on one of the main body part and the thread part; the sliding chute is provided with a first supporting surface; at least one raised strip is arranged on the other of the main body part and the thread part; and the raised strip is provided with a second supporting surface corresponding to the first supporting surface of the sliding chute, the raised strip is accommodated in the sliding chute, and the first supporting surface and the second supporting surface are pressed against each other.

Description

technical field [0001] The invention relates to a mold structure, in particular to a threaded mold. Background technique [0002] During the research and development or mass production of optical lens modules, the torque value of the mutual cooperation between the lens mount and the lens barrel needs to reach the design value, so as to facilitate the adjustment of the focal length. [0003] The method of adjusting the torque usually has the following three directions: 1. Adjust the molding parameters such as the temperature during molding or cooling. During mass production, if the torque value is different due to changes in the temperature and humidity of the workshop, this method is usually used to adjust; 2. To adjust the surface properties such as the thread size of the lens base or the surface roughness of the screw teeth, in the product development stage, the screw teeth of the lens base will be used to adjust the torque, that is to say, for the same lens barrel, It is...
