AI Technical Summary
The injection molds used for the production of existing sensor cover shells cannot be automatically operated during mold release, resulting in inaccurate separation of the mold, which can easily cause the mold to scratch the inner wall of the mold or the operator to contact the high-temperature part with a risk of scalding.
An injection mold including a mold housing, an upper mold seat and a lower mold seat, a secondary cylinder, a main cylinder, a side frame plate, a driving motor, a bidirectional screw and a sliding block are designed. By driving the motor to rotate the bidirectional lead screw, the sliding block drives the upper mold seat and the lower mold seat along the connecting rod, main cylinder and secondary cylinder to move the upper mold seat in the opposite direction, achieving automatic separation, and ensuring the accuracy of separation through the vertical lifting and lowering of the sliding block.
The automatic separation between the upper mold seat and the lower mold seat is achieved, avoiding the risk of scratching the model in the inner wall of the mold, reducing the possibility of operators touching the high-temperature part, and improving the safety and accuracy of operations.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production and processing of sensor cover plate shells, in particular to an injection mold for producing sensor cover plate shells. Background Art
[0002] A sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules. It can meet the requirements of information transmission, processing, storage, display, recording and control. The sensor is an extension of the five senses of human beings, giving objects senses such as touch, taste and smell, making them more "alive". Sensors have the characteristics of miniaturization, digitization, intelligence, multi-function and systematization. The sensor cover shell is one of the important components of the sensor. When the sensor cover shell is produced and processed, an injection mold is required.
[0003] Common injection molds for the production of sensor cover shells are usually composed of molding parts, pouring systems, guide components, and temperature control systems. The heated liquid raw material is injected into the mold through the pouring system and fills the molding cavity. The temperature is then lowered by the temperature control system so that the liquid raw material is cooled and formed in the molding cavity of the injection mold. The molded blank is then taken out. This is the common structure and use of injection molds for the production of sensor cover shells. When demolding, the traditional injection mold for the production of sensor cover shells requires manual pulling of the upper and lower molds, which will cause improper control of the pulling force and easily cause the inner wall of the mold to scratch the model, causing damage to the model. Some injection molds for the production of sensor cover shells add guide structures on both sides of the mold, such as guide columns, to connect the two sides of the mold with the guide structures. When pulling the mold apart, the mold is translated to avoid skewing and the inner wall of the mold scratching the model. However, this method cannot be operated automatically. When the mold is separated, the temperature of the mold is high and the operator may come into contact with the high-temperature part, which may cause a risk of burns. Therefore, an injection mold for producing a sensor cover housing is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an injection mold for producing a sensor cover shell to solve the above-mentioned technical problem that the mold cannot be automatically operated for separation.
[0006] (II) Technical solution
[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: an injection mold for producing a sensor cover housing, comprising:

When the auxiliary connecting tube is connected to the main connecting tube, the auxiliary connecting tube is rotated so that the limit head is connected through the limit grooves.
[0014] Preferably, the inner cavities of the secondary connecting tube and the main connecting tube are both hollow, and a compression spring is transversely arranged in the inner cavity of the main connecting tube. When the secondary connecting tube is connected to the main connecting tube, the end of the compression spring compresses the secondary connecting tube and ensures the connectivity between the secondary connecting tube and the main connecting tube and between the limit head and the limit groove. On the one hand, the connectivity between the secondary connecting tube and the main connecting tube is strong and easy to disassemble and assemble; on the other hand, the upper die base and the lower die base can select different separation structures for use and operation according to different situations.
[0015] Preferably, positioning rods are installed around the bottom of the upper mold base, and positioning holes are opened around the top of the lower mold base, corresponding to the positioning rods, and a molding cavity is opened downward at the top center of the lower mold base.
