Problems solved by technology

[0003] In order to produce inspection wells made of plastic materials, the existing injection molds are basically used for processing, but if processing is required, such as figure 1 In the inspection well shown, since there are branch pipes on the side of the inspection well and a bottom plate in the middle, there are many structures that need to be drawn from the side when opening the mold. Referring to the existing mold structure, it is difficult to design stable injection molding and easy demoulding mold structure

Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as figure 2 As shown, an inspection well mold includes an upper module 1 and a lower module 2 that can be relatively closed or separated, and the upper module 1 can move away or approach relative to the lower module 2 . The lower module 2 is provided with four side drawer blocks 3 that respectively move forward, backward, left, and right. When the side drawer blocks 3 are closed, the upper module 1 can be closed to the top of the side drawer block 3 recently.

[0039] Such as image 3 and Figure 5 As shown, the upper module 1 is provided with an upper core 11, and the lower module 2 is provided with a lower core 21 opposite to the upper core 11. When closing the mold, when the side drawing block 3 is closed to the innermost, It wraps the lower core 21, and at the same time, the upper core 11 can also be inserted into the inside of the side dr...

Abstract

The invention discloses an inspection well mold. According to the technical scheme, the inspection well mold is characterized by comprising an upper mold block and a lower mold block which can be oppositely folded or separated, wherein four lateral pulling blocks which can perform front, rear, left and right displacement correspondingly are arranged on the lower mold block; an upper mold core is arranged on the upper mold block; a lower mold core positioned opposite to the upper mold core is arranged on the lower mold block; the lower mold core and the upper mold core are positioned inside thelateral pulling blocks; when the lateral pulling blocks, the upper mold block and the lower mold block are assembled, an inspection well space is formed among the lower mold core, the upper mold coreand the lateral pulling blocks; locking blocks which can be inserted into the lower mold block through the mold assembling process are arranged on the the upper mold block; and when the upper mold block, the lower mold block and the lateral pulling blocks are folded, the locking blocks are propped against the outer walls of the lateral pulling blocks.

Description

technical field [0001] The invention relates to a mould, in particular to an inspection well mould. Background technique [0002] The inspection well is an auxiliary structure on the pipeline system. Its main function is to conduct regular inspection and clearing of the pipeline system, and also to dredge water flow. Inspection wells are usually set at pipeline crossings, turns, pipeline size or slope changes, water drops, etc., and on straight pipelines separated by a certain distance. At present, in order to improve production efficiency and reduce production costs, most inspection wells are made of plastic. [0003] In order to produce inspection wells made of plastic materials, the existing injection molds are basically used for processing, but if processing is required, such as figure 1 In the inspection well shown, since there are branch pipes on the side of the inspection well and a bottom plate in the middle, there are many structures that need to be drawn from the...
