Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as Figure 1-8 Shown is a preferred embodiment of the present invention.

[0026] A rotary core-pulling mold structure, comprising a formwork 1, an upper formwork 2, a lower formwork 3 and a release plate 4, the lower formwork 3 is fixed on the formwork 1, the upper formwork 2 is constrained on the formwork 1 and located on the lower formwork 3 The upper part can move up and down, and the release plate 4 is constrained on the formwork 1 and can move up and down under the lower template 3. The lower template 3 is fixed with the lower mold 5, and the middle part of the lower mold 5 has a concrete punch part 51. An upper mold 6 is provided, and the injection port is arranged on the upper mold 6. The middle part of the upper mold 6 has a concave mold part 61 that cooperates with the male mold part 51. The inner hole wall of the concav...

Abstract

The invention relates to a rotary core-pulling mold structure. The structure comprises a mold frame, an upper mold plate, a lower mold plate, a lower mold and an upper mold, and is characterized in that the upper mold is arranged in an upper concave cavity of the upper mold plate and can rotate around the axis of the upper mold, a plurality of guide grooves which are arranged along the circumference are formed in the outer circumferential wall of the upper mold, the guide grooves are obliquely arranged from bottom to top, and the inclination directions and angles of the guide grooves are consistent; a plurality of guide blocks corresponding to the guide grooves in a one-to-one mode are fixedly arranged on the lower mold, the guide blocks are obliquely arranged from bottom to top, and the inclination directions and angles of the guide blocks are consistent; and in the mold closing state of the upper mold and the lower mold, the guide blocks are inserted into the guide grooves, and whenthe upper mold moves up and down relative to the lower mold, the upper mold is driven to rotate around the axis of the upper mold through the cooperation effect of the inclined surfaces of the guide blocks and the guide grooves. The rotary core-pulling mold structure is simple and reasonable in structure and low in cost, and is suitable for forming products with inclined grooves on the periphery of the products.

Description

technical field [0001] The invention relates to an injection mold, in particular to a rotary core-pulling mold structure. Background technique [0002] As one of the important molding methods in plastic processing, injection molding is widely used in various fields of industrial production. Injection molds generally include two parts: a movable mold and a fixed mold. The two can be separated or combined. When separated, the blank is loaded or the workpiece is taken out. When the blank is closed, the workpiece is separated or formed. The expansion force has high requirements for structural strength, stiffness, surface hardness, surface roughness and machining accuracy. Therefore, the development level of mold production is one of the important symbols of mechanical manufacturing level. With the rapid development of the national economy, the market The demand for molds continues to grow. In recent years, the mold industry has been developing rapidly at a growth rate of about ...
