Description

Technical Field

[0001] The utility model relates to the technical field of mold manufacturing equipment, in particular to a casting wooden mold with strong moisture resistance. Background Art

[0002] A mold is a tool for producing various industrial products. It is mainly used for processing, molding, and assembling materials. There are many types of molds, including plastic molds, metal molds, wood-plastic molds, etc. The structure and design of the mold need to be determined according to factors such as product shape, size, and material. In the injection molding process, the mold is an important component. It usually consists of a movable mold and a fixed mold. The plastic is melted by an injection molding machine and injected into the mold, and then cooled and solidified. The design and manufacture of the mold need to take into account many factors, such as the shape, size, material, and production efficiency of the product.

[0003] Existing wooden molds are generally integrated, consisting of a model and a core box. Their working principle is mainly to pour the raw materials into the wood to make a mold of the desired shape. Because the mold is made of wood, it will crack due to temperature changes after long-term use. In addition, because raw materials such as molten iron are injected for a long time, if it is soaked in water for a long time, it will be deformed due to the influence of high temperature. At the same time, it is difficult to position the mold plate during replacement, so that the position of the mold plate in the mold cavity is prone to slight changes, resulting in a lower qualified rate of castings. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that cracks may occur due to temperature changes after long-term use, and that deformation may occur due to long-term injection of raw materials such as molten iron and long-term immersion in water, and that the mold plate is difficult to position during replacement, so that the position of the mold plate in the mold cavity is prone to slight changes, resulting in a reduced qualified rate of castings. The utility model proposes a casting wooden mold with strong moisture resistance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A casting wooden mold with strong moisture resistance includes a base, baffles are fixedly installed at both ends of the base, a first mold cavity is fixedly installed on the top of the base, a slide groove is opened on the top of the base, a second mold cavity is slidably connected in the slide groove, mold plates are arranged in the first mold cavity and the second mold cavity, and fixing bolts are installed through threads on the outer surfaces of the first mold cavity and the second mold cavity.

[0007] Preferably, a feed port is provided at the top of the first mold cavity and the second mold cavity, and an injection pipe is fixedly installed in the feed port. The two injection pipes are of the same size and match each other.

[0008] Preferably, positioning holes are provided at the four corners of the outer surface of the first mold cavity, and positioning columns are fixedly installed at the four corners of the outer surface of the second mold cavity, and the positioning holes match the positioning columns.

[0009] Preferably, the number of fixing bolts is set to eight, and they are respectively arranged on the outer surfaces of the first mold cavity and the second mold cavity, the top ends of the eight fixing bolts are located outside the first mold cavity and the second mold cavity, and the bottom ends of the eight fixing bolts are located inside the first mold cavity and the second mold cavity, and fit with the mold plate.

[0010] Preferably, a push-pull rod is provided on the outer surface of the baffle, and one end of the push-pull rod passes through the baffle and fits against the outer surface of the second mold cavity.

[0011] Preferably, a lock buckle is fixedly mounted on the outer surface of the bottom of the first mold cavity, and a lock rod is fixedly mounted on the outer surface of the bottom of the second mold cavity, and the lock buckle and the lock rod are adapted to each other.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model replaces the traditional integrated mold plate by separately setting up the first mold cavity, the second mold cavity and the mold plate, so that the mold plate is separated from the mold cavity. When the mold plate is deformed due to long-term work or water immersion, it only needs to be replaced with a new mold plate instead of the entire integrated mold plate, thereby reducing the use cost.

[0014] 2. By setting fixing bolts, locking rods and locking buckles, the mold plate is placed in the first mold cavity and the second mold cavity, and the positioning rod on the second mold cavity is inserted into the positioning hole of the first mold cavity through the push-pull rod, and then they are fit together, and fixed by the locking rod and the locking buckle, and then the fixing bolts are tightened to fix the mold plate in the first mold cavity and the second mold cavity, so that misalignment will not occur, thereby improving the qualified rate of castings.
