Problems solved by technology

This type of mold has a simple structure and is easy to manufacture, but it is labor-intensive and low in production efficiency; the motorized thread removal is driven by a hydraulic system, and the thread is removed by using the relative rotation and relative movement of the plastic part and the threaded ring. The main disadvantage of this core-pulling mechanism It is necessary to increase the hydraulic system and other related equipment to increase the cost of the mold, and the structure is complex and the manufacturing cost is high

Embodiment Construction

[0014] refer to Figure 1 to Figure 2 , a demoulding structure of the present invention, comprising a mold base and a mold core arranged inside the mold base, the mold core includes an upper mold core 2-1, which cooperates with the upper mold core 2-1 to form a mold The lower mold core 2-2 of the cavity, and the core 3 arranged between the upper mold core 2-1 and the lower mold core 2-2, the surface of the core 3 is provided with a screw thread 3-1, the The mold core is also embedded with a pin 2-21 for inserting into the thread 3-1 and rotating and guiding the movement track of the core 3. The block seat 4 and the inclined guide post 5 inserted into the slider seat 4 and driving the slider seat 4 to move away from the mold core, the inclined guide post 5 is fixed in the mold frame.

[0015] As an improvement of the above technical solution, the mold base includes an upper mold base 1-1 with an upper mold core 2-1 installed, and a lower mold base 1-2 with a lower mold core 2-...

Abstract

The invention discloses a demolding structure. The structure comprises a mold frame, and a mold core arranged in the mold frame; the mold core comprises an upper mold core body, a lower mold core matched with the upper mold core to form a mold cavity and a core arranged between the upper mold core and the lower mold core, a thread is arranged on the surface of the core, a plug pin used for being inserted into the thread and rotating and guiding the motion track of the core is embedded in the core, the core is rotatably connected with a sliding block base arranged outside the mold core and an inclined guide column inserted in the sliding block base and driving the sliding block base to move in the direction away from the mold core, and the inclined guide column is fixed into the mold frame.The inclined guide column is used for driving the sliding block base to slide, the core is driven to be rotated out of the mold core, demolding is achieved, in the whole process, extra hydraulic equipment is avoided, and cost is reduced.

Description

technical field [0001] The invention relates to the field of molds, in particular to a demoulding structure. Background technique [0002] At present, the methods for demolding the external threads of plastic molds mainly include: manual thread removal, which is after the plastic part is formed and the mold is opened, the ring is unscrewed from the plastic part by hand or with a simple tool. This type of mold has a simple structure and is easy to manufacture, but it is labor-intensive and low in production efficiency; the motorized thread removal is driven by a hydraulic system, and the thread is removed by using the relative rotation and relative movement of the plastic part and the threaded ring. The main disadvantage of this core-pulling mechanism It is necessary to increase the hydraulic system and other related equipment to increase the cost of the mold, and the structure is complicated and the manufacturing cost is high. Contents of the invention [0003] The presen...
