Background
At present, when products such as an elliptical blowing nozzle are produced, because the sliding blocks are arranged on the dies on the two side faces of the product, and the sprue of the product is arranged between the two sliding blocks, the sprue is connected with the product after the die sliding blocks are opened after the product is processed by a traditional method, the sprue is manually removed after the product falls off, and the manpower resource is wasted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can break the runner automatically with the help of slider die sinking automatic break runner injection mold's scheme when the mould is opened.
The technical scheme of the utility model as follows:
an injection mold capable of automatically breaking a sprue by means of a slide block mold opening comprises a slide block assembly, a movable mold push plate and a movable mold core from top to bottom in sequence; the sliding block assembly comprises a first sliding block and a second sliding block which are oppositely arranged, a plurality of first accommodating grooves are uniformly distributed on the working surface of the first sliding block, a plurality of second accommodating grooves corresponding to the first accommodating grooves are uniformly distributed on the working surface of the second sliding block, and accommodating spaces corresponding to the shapes of products are formed between the first accommodating grooves and the corresponding second accommodating grooves; the movable mould push plate is provided with a pouring device, and the pouring device comprises a main runner and a sub-runner assembly; the main runner passes through a gap area between every two products, and a sub-runner assembly is arranged on the main runner close to a product pouring gate; the sub-runner assembly comprises a first sub-runner and second sub-runners extending outwards from two sides of the first sub-runner, and a pouring gate at the other end of each second sub-runner is connected with a corresponding product bulge.
A first false flow channel and a first false flow channel are respectively arranged on two second branch flow channels of the branch flow channel assembly, the first false flow channel is parallel to the second false flow channel, the first false flow channel is connected with the first slide block, and the second false flow channel is connected with the second slide block
The number of the first accommodating grooves and the number of the second accommodating grooves are four; the two branch runner assemblies are respectively arranged on the main runner of the leftmost gap area and the main runner of the rightmost gap area.
The main runner is S-shaped.
The utility model has the advantages that: 1. the utility model arranges a column-shaped false flow channel on the vertical part of the main flow channel to twist off the sprue when the slide block is opened; a false runner added on the second sub-runner has a certain included angle with the demoulding direction of the slide block, and the length is about seven-eight millimeters, which is equivalent to adding a back-off on the slide block of the mould;
2. because the false runner is embedded into the sliding blocks at the two sides, the false runner can be forcibly shifted when the two sliding blocks are opened, so that the first sub-runner, the second sub-runner and the pouring gate are forced to rotate, and the pouring gate is broken; and then the runner and the product are ejected out of the mold through the push plate and the ejector pin, the product automatically falls off, and the runner is clamped away by the manipulator.
